Description

Liquid cooling distribution device used in server cabinet

The invention relates to a liquid cooling distribution device used in a server cabinet, in particular to a liquid heat dissipation device arranged in the server cabinet.

Advances in technology can enhance the convenience of human life. In particular, all kinds of data processing and Internet applications currently rely on the operation of electronic devices. Therefore, electronic devices with high-speed processing performance and large energy storage are widely used. Used in various enterprises. Take the traditional servo chassis (cabinet) structure that can accommodate various heating elements for IT, communications, industry, transportation, transportation, etc., as an illustration. The interior of the servo chassis (cabinet) is a closed accommodating space. The placement space is capable of accommodating 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.). It is generally known that enclosed heat dissipation is used The method (ie heat dissipation in the servo cabinet) is that the heating elements are directly provided with water cooling heads and attached to each heating element, and a working fluid inside is brought into the servo cabinet through a pipe body group and a pump The water drain is used to dissipate heat, and the air in the housing space of the chassis (cabinet) is driven by the fan installed on the water drain, so that the working fluid in the water drain absorbs heat and the air in the cabinet (cabinet) exchanges heat. , In order to achieve the heat dissipation effect and reduce the temperature of each heating element. However, the enclosed (in the servo cabinet) heat dissipation method will cause the servo cabinet to increase in temperature with the increase of working time and form heat accumulation, which will cause the heat to fail to dissipate, resulting in poor heat exchange effect. Therefore, some companies also adopt open heat dissipation, that is, heat exchange through the water drain or cold water outside the servo cabinet. However, the conventional method is to install a cooling distribution unit (Cooling Distribution Unit; CDU) inside 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 through the cold water distribution device and an external water source, and through the cold water distribution device and a heat source in the servo cabinet The fluid circuit on the second side helps the servo cabinet to dissipate heat. However, the above-mentioned other conventional technology needs to be repaired when the internal parts of the cold water distribution device (such as pipe body or joints or pumps or other components, etc.) fail to be repaired, and the operation of the servo cabinet and the cold water distribution device must be stopped, and the operation of the cold water distribution device must be stopped. Start both, so time wasting. In addition, the whole cold water distribution device must be pulled out (drag) from the servo cabinet during maintenance, but for the servo cabinet placed in a small space, there is no way to pull out the whole cold water distribution device and open the shell for maintenance. , Resulting in difficult maintenance. Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the inventor of this case and the related manufacturers engaged in this industry urgently want to study and improve.

As shown in the figure, the movable housing portion 1121 is opened relative to the base 111 to form an opening 1123 communicating with the internal space 113. The movable housing portion 1121 is connected to the internal space 113 via a movable connection means (such as a screw lock or a hinge or a sliding groove or a linear slide rail). Etc.) is connected to the base 111. In some implementations, the movable shell portion 1121 is, for example, an upwardly-opening top cover (as shown in Figure 2A), or a side-opening cover (as shown in Figures 2B and 2D), or a sliding opening Slide cover (as shown in Figure 2C), or double flip cover (as shown in Figure 2E). It should be noted that if it is a sliding cover type, in one implementation, one of the movable housing 1121 and the base 111 is provided with a male chute and the other is provided with a female chute to match the male chute, in another implementation A linear slide rail is provided between the movable housing 1121 and the base 111. In the case of a single-side clamshell type or a double clamshell type, the movable housing 1121 is connected to the base 111 by a hinge.

As shown in the figure, the body 11 of the aforementioned liquid cooling distribution device is arranged in the server cabinet 30, leaving only the front end plate 1111 of the base 111 exposed. When the first pump 12 or the second pump 13 fails, the The main body 11 is partially drawn out from the server cabinet 30 along the drawing direction L, that is, it is drawn until the movable housing 1121 is exposed. Therefore, the main body 11 does not need to be completely drawn out from the server cabinet 30 to maintain the The fixed shell 1122 is in the server cabinet 30, and then the movable shell 1121 is opened to expose the internal parts such as the first pump 12 and the second pump 13, but not limited to this, such as a part of the transmission tube set 17 or the first and second connecting head groups 14 and 15 will also be exposed. In this embodiment, the first pump 12 is replaced. By loosening the first connecting head group 14 to disassemble the first pump 12, this At this time, the second pump 13 (as shown in FIG. 1B) can still keep running without interrupting the operation of the server cabinet 30. This creation has been described in detail above, but what is described above is only a preferred embodiment of this creation, and should not limit the scope of implementation of this creation. That is to say, all equal changes and modifications made in accordance with the scope of this creation application shall still fall within the scope of the patent coverage of this creation.
