Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation, and more particularly to a liquid cooling heat dissipation system. Background Technology

[0002] With the advent of the era of big data and the Internet, the processing power of various electronic computer devices is increasing day by day, and the heat they generate is also increasing. Therefore, how to effectively dissipate heat from the cabinets that house these electronic computer devices is a key factor that directly affects the performance and lifespan of these electronic computer devices. On the other hand, under the demand for energy saving, how to achieve better heat dissipation with lower power consumption is also a topic of concern.

[0003] Existing rack-mounted liquid cooling systems include cold plates, manifolds, coolant distribution units (CDUs), and chillers. The manifolds include a first fluid manifold and a second fluid manifold. The cold plates are used in conjunction with computer equipment stored in the rack, with each cold plate in thermal contact with the heat source of the corresponding computer equipment. Each cold plate has a cold plate inlet and a cold plate outlet. The first fluid manifold has a first manifold inlet and a first manifold outlet corresponding to each cold plate, and the second fluid manifold has a second manifold inlet and a second manifold outlet corresponding to each cold plate. The coolant distribution unit has a first coolant distribution inlet, a first coolant distribution outlet, a second coolant distribution inlet, and a second coolant distribution outlet. The chiller has a chiller inlet and a chiller outlet. Through the interconnection of these components, a circulating heat exchange is achieved.

[0004] However, while existing liquid cooling systems have heat dissipation performance, they have the following problems to be solved in actual use. Because they cool down by using ice water, the overall size becomes quite large, which is obviously not suitable for miniaturized intelligent data processing systems (such as DeepSeek) that do not have particularly high heat dissipation requirements.
