Therefore, the application provides an air cooling and liquid cooling combined refrigeration system and a data center, and the air cooling and the liquid cooling refrigeration are integrated, so that the heat dissipation efficiency is improved.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. It should be apparent that the embodiments described in this application are only a part of the embodiments of the present application, and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

The first device group 21 and the second device group 22 may each include several air-cooling devices 211 and several heat-generating devices 212. The heat generating device 212 may be a server cabinet or other device that generates a large amount of heat during normal operation. The air cooling device 211 is configured to cool the hot air flowing out of the closed hot air channel 23, so as to maintain a cold environment in the closed area 1, and thus dissipate heat generated by the heat generating component in the heat generating device 212. The circulating liquid cooling system 3 is connected to the primary heat sources (for example, service-period cabinets, which may be CPUs, GPUs, etc.) of the plurality of heat-generating devices 212 to cool and dissipate the primary heat sources of the heat-generating devices 212, and the plurality of air-cooling devices 211 cool the hot air exhausted from the closed hot channel 23 to cool and dissipate the heat of the heat-generating devices 212.

In practical use, the air-cooling and liquid-cooling combined refrigeration system can be applied to the data center for heat dissipation of the service cabinet. Correspondingly, the air cooling device 211 may be a train-to-train air conditioner, and the heat generating device 212 may be a server cabinet. And the circulating liquid cooling system 3 is used for radiating the CPU and the GPU in the server cabinet.

The male contact 42 is connected to the heat exchange box 41, and one end of the male contact 42 is located in the internal cavity of the heat exchange box 41, so that the male contact 42 can exchange heat with the liquid in the internal cavity of the heat exchange box 41. One end of the female contact 43 is detachably connected to the other end of the male contact 42, and the other end of the female contact 43 is in contact with the primary heat source of the heat generating device 212. In this way, the primary heat source of the heat generating device 212 can transfer heat into the internal cavity of the heat exchanging box 41 through the female contact 43 and the male contact 42, so as to exchange heat with the liquid in the internal cavity of the heat exchanging box 41. Meanwhile, the liquid in the liquid cooling circulating system is not in direct contact with the heating source, and the damage to heating equipment caused by liquid leakage can be effectively avoided.

In practice, the male contact 42 may be welded to the heat exchange box 41 and ensure that there is a portion of one end of the common contact 42 located within the interior cavity of the heat exchange box 41. Of course, the male contact 42 may be formed integrally with the heat exchange box 41, and the present application is not limited thereto. The male contact 42 and the female contact 43 can be connected in a plug-in manner, so as to facilitate maintenance and replacement. The male contact 42 and the female contact 43 may be made of a thermally conductive material, such as copper, iron, or the like.

It should be noted that the specific structure of the heat transfer assembly 4 is only one embodiment of the present application, but not limited thereto. The heat transfer component 4 may also be a circulation conduit, which guides the liquid into the heat generating device so as to attach/cover the primary heat source (or directly soak the heat generating device), thereby dissipating heat from the primary heat source of the heat generating device 212.
