Description

Liquid cooling distribution device used in server cabinet

Technical Field

The utility model relates to a liquid cooling distributor for in server rack indicates a liquid heat abstractor who sets up in server rack especially.

Background

The advancement of technology can improve the convenience of human life, especially the operation of various data processing and internet networks at present, so that the electronic equipment with high-speed processing efficiency and large energy storage capacity is widely used in various enterprises.

The server case (cabinet) structure for IT, communication, industry, transportation, etc. is used to describe the traditional server case (cabinet) structure capable of accommodating various heating elements, the inside of the server case (cabinet) is a closed accommodating space for accommodating a plurality of heating elements (such as Central Processing Unit (CPU), microprocessor or chip or single chip or other units or devices generating heat source due to electric drive, etc.), the existing method generally adopts a closed heat dissipation manner (i.e. heat dissipation in the server cabinet), wherein the heating elements are directly provided with water cooling heads to be attached to the heating elements, a pipe group and a pump are used to carry out heat dissipation on water drainage in the server cabinet, and a fan arranged on the water drainage drives air in the accommodating space of the case (cabinet) to make the heat-absorbing working fluid in the water drainage and the air in the case (cabinet) perform heat exchange action, so as to achieve the purposes of heat dissipation and temperature reduction of each heating element. However, the enclosed heat dissipation method (inside the server cabinet) will cause the server cabinet to generate heat accumulation with the increase of the working time, which results in heat unable to dissipate, and thus poor heat exchange effect.

Therefore, there are also manufacturers who adopt open heat dissipation, that is, heat exchange is performed by water or cold water outside the server cabinet, but in this way, a cold water distribution Unit (CDU) is additionally disposed in the server cabinet, and a plate heat exchanger, a water storage Unit, a pump, etc. are disposed in the cold water distribution Unit, and a first side fluid loop is formed by the cold water distribution Unit and an external water source, and a second side fluid loop is formed by the cold water distribution Unit and a heat source in the server cabinet, so as to help the server cabinet dissipate heat.

However, the above-mentioned another prior art needs maintenance when internal parts (such as pipes or joints or pumps or other elements) of the cold water distribution device are failed, and it is necessary to stop the operation of the server cabinet and the cold water distribution device, wait for the maintenance to be completed and then restart the server cabinet and the cold water distribution device, and thus it takes time. Moreover, the whole cold water distribution device must be pulled out (dragged) from the server cabinet during maintenance, but for the server cabinet placed in a narrow space, the whole cold water distribution device cannot be pulled out to open the shell for maintenance, so that the maintenance is difficult. Therefore, how to solve the above-mentioned problems and disadvantages is a direction in which the inventors of the present invention and related manufacturers engaged in the industry need to research and improve.
