Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an emergency protector for a server rack,

More particularly, the present invention relates to an emergency protection device for a server rack, and more particularly, to an emergency protection device for a server rack, And opening the rear door so as to safely protect the server mounted inside the rack rack.

Further, the present invention relates to an emergency protection device for a server rack using an electromagnet lock (EM lock), which is improved and improved by the applicant's specification No. 10-1468874 (emergency protection device for server rack) .

In general, a rack refers to the international standard (IEC) for the installation of network equipment and computer equipment including servers, and is a rack-mount system that is stacked in layers for the configuration and installation of computer equipment such as servers and hubs. It is manufactured as a server rack / hub rack / communication rack / network system rack / CCTV rack / multi rack according to the computer equipment to be mounted, and it is called 19 inch rack / 21 inch rack depending on the external size of the computer equipment.

In addition, depending on the functions provided, it is possible to use a sealed rack (a rack that provides a dust inflow and shutoff function), a seismic rack (a rack with vibration prevention function against an earthquake), EMP shielding force (electromagnetic pulses, EMC shelter racks (EMC reduces the noise of electronic devices to prevent them from affecting the operation of other electronic devices, and prevents other electronic devices from being damaged. An EMI shielding rack (a rack with electromagnetic shielding), a non-vibration rack (a rack with the ability to prevent external physical shaking for ships and vehicles) And so on.

In the present invention, the above-mentioned various kinds of racks are collectively referred to as server racks. Servers and computer equipment installed in the above-described server racks can have catastrophic consequences such as system stoppage and failure if the heat load due to highly integrated high performance is not removed.

In general cooling method of such heat load, a separate computer room is formed and the cooled load is blown by blowing the cooled air through the air conditioning unit inside the rack box. When the computer room can not be operated separately due to cost and space problems, And a fan for ventilation is provided inside to correspond to the heat load.

However, when the computer room for server rack is operated separately, cooling air passing through the air conditioning unit must be supplied to the inside of the rack box. Therefore, there is no blocking method against dust inflow, and the temperature due to the connection cable connection of various information processing apparatuses and the heat island phenomenon in the computer room Due to the unbalance of control, the back side of the server rack is often opened to improve efficiency, and thus it can not be prepared against external dust inflow.

On the other hand, in a rack (a cabinet in which various information processing apparatuses such as servers are installed), a blowing fan that can be mounted on a rack box is miniaturized in order to save space when the information processing apparatuses are installed, The server or the information processing apparatus may be seriously damaged, resulting in economic loss and loss of data information.

One of the major reasons for the major failure of the servers and the information processing devices of the server rack is a problem caused by an overload caused by failure in temperature control. To solve this problem, as described above, ) Are generally operated.

However, in the computer room where the server rack is installed, centralized cooling is used to control the indoor temperature, and air for removing the heat load is supplied to the inside of the computer room. In order to smoothly supply and discharge the air inside the computer room, So that sufficient ventilation can be achieved.

Therefore, in order to remove the amount of heat generated in the server rack, the amount of heat generated in the entire internal space of the computer room must be removed as well, so that energy loss is very large.

In addition, it is impossible to supply enough air to the highly integrated server, and the heat of the rear side of the rack is recirculated to the inlet of the front side of the rack, which can not sufficiently remove the heat load in the rack, Costs of management personnel are incurred.

In addition to the server racks in the computer room, the server racks of the basic type use a perforated plate or the like to increase the ventilation area for heat exchange of the rack box itself for temperature control so that the forcedly cooled air is introduced into and discharged from the inside of the rack housing Structure is required.

Therefore, it is possible to manage the room temperature and humidity by separately controlling the computer room due to the air supply and exhaust system. However, there are problems such as generation of static electricity due to the fine dust introduced into the rack box, malfunction of leakage, spark, It is very disadvantageous to the operation and management of the computer room.

The following describes the prior art related to server racks.

In Reference 1, cool air blown from the air conditioning unit is supplied to the lower air supply mechanism of the rack, and the equipment in the rack is cooled by the cool air, and the air discharged from the air exhaust port is returned to the air conditioning unit A cooling structure of a rack is disclosed.

In Reference 2, cool air is supplied from the cooler unit to a downflow unit detachably installed on the upper portion of the front surface of the server rack through the exchange panel, the cool air is forcedly blown by the downflow unit to cool the electronic equipment, And the waste heat of the unit is exhausted to the outside through the outdoor exhaust duct.

In Reference 3, a plurality of server modules, each having a main circulation pipe, a main circulation pump, and a cooling unit installed in a rack cabinet, cooling the main circulation pipe and installing a pump in the water collection unit, Cooling system in which a coolant is supplied and drained, and a cooler for cooling the heat-generating unit in each server module is connected to the rack-mount server system.

Reference 4 discloses a radiator unit having a fan unit in which a plurality of fans arranged to discharge heat generated from a heat source from a rack and pipes for guiding a coolant for releasing heat discharged from the rack by rotation of the fans And a heat exchanger for circulating the refrigerant connected to the pipe.

In Reference 5, a shield finger is disposed along the periphery of a front door opening of an upper body accommodating a server or a router in an inner space, and a lower body Discloses a server rack in which a shield finger is disposed along the periphery of an opening of a lower front door.

Reference 6 also discloses a server rack in which a cabinet completely surrounds the rack unit, a plenum is formed between the rack unit and the rack box, and filler material is filled therebetween to prevent noise by the sound absorbing material.

In order to shield the server rack, it is modularized into a power line inlet of a rack box, an optical cable inlet, a distributor, or the like so as to have a dust shielding structure so that there is no problem in operation and monitoring of servers and information processing apparatuses, The present invention solves the above-mentioned problem caused by fine dust by intrinsically blocking the inflow of fine dust into the inside of the server rack, and also provides a humidification effect together with supply of cooling air to the dust rack- A server rack capable of operating and managing more stably and efficiently by solving the above-mentioned problems that may be caused by a heat load by making it possible to supply high-quality air with a high efficiency,

Reference 8 also includes a server storage rack, an exhaust duct, and a control box duct to form a server rack / communication rack and a constant-temperature / humidity-free structure outside the room. And to control the temperature and humidity of a server and network equipment so that noise can be prevented.

As described above, the server rack requires a constant temperature and humidity function to maintain optimum temperature and humidity for the protection and safe operation of the computer equipment mounted in the rack box, thereby enabling optimum efficiency and stable operation. In addition, Since the inflow of dust and dirt will lead to equipment operation troubles, it is also very important to prevent the inflow of dust. Also, computer equipment and network equipment are very vulnerable to fire.

As a result, the server rack is equipped with a constant temperature and humidity module that can maintain constant temperature and humidity at all times in order to ensure stable operation with optimum efficiency.

However, when the temperature and humidity module does not operate due to power failure or other causes, the internal temperature of the rack is increased due to the heat of the computer, so the server rack can not perform its function.

That is, if the operation of the thermo-hygrostat module is interrupted due to power failure or malfunction, the internal temperature of the rack is increased by the heat load of the server, the computer equipment, etc., Causing a fatal problem such as shutdown or damage.

Accordingly, the present applicant has found that, in an emergency such as interruption of the constant temperature / humidity module or occurrence of abnormally high temperature, the inside air of the high temperature rack is forcibly discharged to the outside and at the same time the outside air is sucked to ventilate and cool the inside of the rack, (Fig. 9). In this paper, we have developed an emergency protection system for server racks that allows continuous operation of computer equipment in a rack without interruption.

Thus, the computer equipment in the rack can be maintained continuously without interruption.

In addition, by connecting to the UPS (Uninterruptible Power Supply) power supply, emergency protection device can be operated even in case of power failure. In case of emergency in case of abnormality of server rack, interruption of constant temperature and humidity due to power failure, And the exhaust fan is operated to operate the emergency protection device to prevent the internal temperature of the rack from rising.

However, this emergency protection device may be configured to operate only when power is always supplied from the UPS power supply in the event of a power failure, so that power can not be supplied from the UPS power supply. In this case, if the power supply is completely cut off, Since the device does not work, it has been required to develop a new emergency protection device in case of emergency.

In other words, if the power is cut off due to a power failure, etc., the emergency protection device operates automatically regardless of the UPS power supply (that is, even when power is not supplied from the UPDS power supply), so that the server rack can be safely protected even in case of power failure It was necessary to develop a device.
