Description

  The present invention relates to a cool air circulation system for a cabinet in which electronic and electrical devices are mounted on a mount angle and the inside can be cooled by a cooling device.

  Since warm air is exhausted from electronic and electrical equipment, air passages are created in the cabinet to exhaust the warm air to the outside, and cooling devices such as ventilation fans and air conditioners are installed to provide forced ventilation. The temperature rise in the cabinet was suppressed. Conventionally, when forced ventilation is performed using an air conditioner, cold air is sent from the air conditioner 31, and the electronic / electrical device 32 draws the cold air and discharges the air heated in the device. Air was circulating.

However, in the above method, the cool air exhausted from the air conditioner 31 and the warm air exhausted from the electronic / electric device 32 are mixed and the heat exhaust efficiency is poor. A device has been used in which an intake pipe is provided in the vicinity of the fan 33 and the other end of the intake pipe is connected to a suction port of a cooling device or is opened outside the cabinet.
JP 2001-358484 A

  However, in the cold air circulation system shown in Patent Document 1, a space for installing the intake pipe is required inside the cabinet, and the space A that conventionally stores the electric wires for wiring between the electronic and electrical devices is reduced. was there.

  Therefore, the present invention has an object to provide a cool air circulation system for a cabinet that has a simple structure and increases exhaust heat efficiency without reducing the amount of radiation, and the structure is such that the cool air outlet from the cooling device is an electronic / electrical device. In addition to being arranged on the suction port side of the device, the cabinet is provided with a partition wall that separates the suction port and the discharge port of the electronic / electrical device.

  In the cool air circulation system for a cabinet according to the present invention, the cool air outlet from the cooling device is disposed on the inlet side of the electronic / electric device, and the inlet / outlet of the electronic / electric device is isolated from the cabinet. Since the partition wall is provided, it is possible to prevent the rewinding of the heat accumulation and warm air again by the electronic / electrical device, and the exhaust heat efficiency can be increased. In addition, it is considered that the load on the cooling device can be reduced by cutting off the cool air discharged from the cool air device and the warm air discharged from the electronic / electrical equipment, and the life can be extended.

  An embodiment of a cool air circulation system for a cabinet according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The cabinet 1 is provided with a mount angle 2, and an electronic / electrical device 3 is fixed to the mount angle 2 and stored in the cabinet 1. The electronic / electrical device 3 is generally a device called a front mount type. A fixing hole (not shown) is provided on the front side of the device, and the front side of the device is fixed to the mount angle 2 by screwing or the like. There are many.

  In many cases, the intake port of the device is provided on the front side and the exhaust port is provided on the back side, and the air on the front side of the cabinet 1 is sucked and the warmed air is discharged on the back side. In order to collect cool air on the front side, it is necessary to prevent warm air discharged to the back side from flowing around to the front side. Therefore, for example, a partition wall 4 is attached to the mount angle 2 so that the air intake surface of the device is isolated.

  A discharge hole 6 for discharging the cool air of the cooling device 5 such as an air conditioner is installed on the intake port side of the device 3 housed in the cabinet 1, and the intake hole 7 of the cooling device is a warm air heated through the device. Place on the exhaust side. Since the front side of the cabinet 1 (the intake side of the equipment) and the back side (the exhaust side of the equipment) are separated by the partition wall 4, the cold air discharged from the cooling device 5 such as an air conditioner is To the side and the device draws in cold air only. The warm air discharged from the device is sucked into the intake hole 7 of the cooling device 5 such as an air conditioner, so that the warm air is not sucked into the device again, and the heat can be efficiently exhausted.

  Since it is sufficient that the warm air does not enter the intake side of the device 3, the structure is such that the warm air discharged from the device is discharged to the outside of the cabinet 1, and the shape of the partition wall 4 is not particularly limited.

  Air is isolated inside the cabinet by providing a partition, but the partition 11 can be mounted on the side and back as shown in FIG. Is possible.

It is explanatory drawing which shows the cold air circulation system which concerns on this invention. It is sectional drawing in FIG. It is explanatory drawing which shows the cold air circulation system which concerns on this invention. It is explanatory drawing which shows the cold air circulation in the conventional cabinet. It is explanatory drawing which shows the flow of the air in the conventional cabinet.
