Description

Liquid cooling distribution device in server cabinet

The present invention relates to a liquid cooling distribution device used in a server cabinet, and more particularly to a liquid cooling device provided in the server cabinet.

Advances in science and technology can improve the convenience of human life, especially the current use of various data processing and the Internet depends on the operation of electronic equipment. Therefore, electronic equipment with high-speed processing performance and large storage energy is widely used. Used in various enterprises.         
The traditional servo housing (cabinet) structure that can accommodate various heating components in IT, communication, industry, transportation, and transportation is described as an example. The interior of the servo housing (cabinet) is a closed accommodation space. The installation space can accommodate multiple 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 heat due to electric power, etc.). It is generally known that closed heat dissipation is used. The method (that is, the heat dissipation in the servo cabinet) is to directly set a water cooling head on each of these heating elements and attach them to each heating element, and bring a working fluid inside to the servo cabinet through a tube group and a pump. The water exhaust pipe dissipates heat and drives the gas in the housing space of the chassis (cabinet) through the fan installed on the water exhaust pipe, so that the working fluid that absorbs heat in the water exhaust pipe and the gas inside the chassis (cabinet) perform heat exchange. In order to achieve the purpose of heat dissipation and reduce the temperature of each heating element. However, the closed type (inside the servo cabinet) heat dissipation method will cause the servo cabinet to increase in temperature with the increase of working hours, which will cause heat accumulation to cause heat to be dissipated, resulting in poor heat exchange effect.          Therefore, some companies have adopted open cooling, that is, heat exchange through water drains or cold water outside the servo cabinet. However, it is known to adopt this method to install a cooling water distribution unit (CDU) in the servo cabinet. The cold water distribution device is provided with a plate heat exchanger, a water storage unit, a pump, etc., and forms a first-side fluid circuit with an external water source through the cold water distribution device, and is formed with the heat source in the servo cabinet through the cold water distribution device. The second side fluid circuit helps the servo cabinet dissipate heat.         
However, the above-mentioned another conventional technique requires repairs in the event of failure of internal parts of the cold water distribution device (such as pipes or joints or pumps or other components, etc.). The servo cabinet and the cold water distribution device must be stopped and operated again after the maintenance is completed Start both, so it takes time. Furthermore, the entire cold water distribution device must be pulled (pulled) out of the servo cabinet during maintenance, but for the servo cabinet placed in a small space, there is no way to pull the whole cold water distribution device out to open the casing for maintenance Make maintenance difficult. Therefore, how to solve the above-mentioned problems and shortcomings, that is, the new people in this case and the relevant manufacturers engaged in this industry are eager to study the improvement direction.
