Grouping type liquid cooling module and liquid cooling server Technical Field The invention relates to the technical field of server liquid cooling and heat dissipation, in particular to a grouping type liquid cooling module. In addition, the invention also relates to a liquid cooling server comprising the grouping type liquid cooling module. Background With the rapid development of technologies such as artificial intelligence, high-performance computing and big data analysis, the power consumption and the heat productivity of hardware such as an internal Graphics Processor (GPU) are increasingly increased as a server of a core computing power bearing platform. The traditional air cooling heat dissipation scheme is more and more difficult to meet the heat dissipation of the high-performance hardware, and has the disadvantages of high energy consumption, high noise and the like. The liquid cooling scheme can efficiently realize heat dissipation of hardware and chips deployed in high density by means of liquid medium circulation. However, the liquid cooling servers in the market at present, particularly cold plate type liquid cooling servers, still have some defects in structural design, mainly adopt the following two integrated packaging forms: 1. And in the integral integrated packaging mode, all the cold plate units of the hardware of the same type in the server are connected in parallel through a liquid cooling pipeline and integrated into an indivisible liquid cooling module. However, the whole machine is only provided with 1 module of the same type, no redundancy design exists, and when any hardware or a corresponding cold plate unit fails, the whole liquid cooling module is required to be disassembled, so that the whole server is forced to stop working, and the operation continuity of the server is affected. In addition, such a structure generally leads to non-visual leakage inspection, is difficult to accurately locate leakage points, and has potential safety hazards. 2. And in the grouping and integration packaging mode, cold plate units of the same type of hardware are packaged in groups and connected in parallel, and the number of the liquid cooling modules of the same type of whole machine is more than 1. The packaged cold plate unit still cannot be disassembled independently in the module, and the whole module still needs to be replaced during maintenance. In addition, such structures often lead to messy exterior liquid cooling plumbing layouts, poor aesthetics, and high assembly costs. Therefore, how to solve the defects of poor maintainability, lack of effective redundant design, unreliable liquid leakage detection and unattractive overall layout of the cold plate packaging scheme of the existing liquid cooling server is a problem to be solved by those skilled in the art. Disclosure of Invention The embodiment of the invention aims to provide a group type liquid cooling module and a liquid cooling server, wherein the group type liquid cooling module realizes hardware redundancy design, and can be used for rapidly disassembling and maintaining a failed liquid cooling module independently, so that the operation continuity and reliability of the liquid cooling server are improved, and the maintenance efficiency of the liquid cooling server is improved.
