Description

Liquid cooling distribution unit for use in server cabinets

technical field

The utility model relates to a liquid cooling distribution device used in a server cabinet, in particular to a liquid cooling device arranged in the server cabinet.

Background technique

The advancement of science and technology can improve the convenience of human life. In particular, various data processing and the use of the Internet all rely on the operation of electronic equipment. Therefore, electronic equipment with high-speed processing performance and large energy storage is widely used. Widely used in various enterprises.

Taking the traditional existing server chassis (cabinet) structure that can accommodate various heating elements in IT, communication, industry, transportation, transportation, etc. as an illustration, the inside of the server chassis (cabinet) is a closed accommodating space. The accommodating space can accommodate a plurality of heating elements (which can be a central processing unit (CPU), a microprocessor or a chip or a single chip, or other units or devices that generate a heat source due to electric drive, etc.), and currently, closed heat dissipation is generally used. The method (that is, the heat dissipation in the server cabinet) is that the heating elements are directly provided with water-cooling heads attached to each heating element, and a working fluid inside the server cabinet is brought to the water inside the server cabinet by means of a pipe body group and a pump. The air in the accommodating space of the case (cabinet) is driven by the fan installed on the water line, so that the working fluid in the water line that absorbs heat and the air in the case (cabinet) exchange heat with the air inside the case (cabinet). To achieve the effect of heat dissipation, reduce the temperature of each heating element. However, the closed (inside the server cabinet) heat dissipation method will cause the server cabinet to increase in temperature with the increase of working time, resulting in the accumulation of heat, and the heat cannot be dissipated, resulting in poor heat exchange effect.

Therefore, some manufacturers also adopt open heat dissipation, that is, heat exchange is carried out through the water drain or cold water outside the server cabinet. However, this method is currently adopted in the server cabinet. The cold water distribution device is provided with a plate heat exchanger, a water storage unit, a pump, etc., and the first side fluid circuit is formed by the cold water distribution device and an external water source, and the second side is formed by the cold water distribution device and the heat source in the server cabinet. Fluid circuits, which help dissipate heat from the server cabinet.

However, in the other prior art mentioned above, when the internal parts of the cold water distribution device (such as pipes or joints or pumps or other components, etc.) fail to be repaired, the operation of the server cabinet and the cold water distribution device must be stopped and restarted after the repair is completed. Start both, so time consuming. Furthermore, during maintenance, the whole cold water distribution device must be pulled (pulled) out of the server cabinet, but for the server cabinet placed in a small space, there is no way to pull out the whole cold water distribution device to open the shell for maintenance. Makes maintenance difficult. Therefore, how to solve the above-mentioned existing problems and deficiencies is the direction that the inventor of this case and the relevant manufacturers engaged in this industry are eager to research and improve.
