Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for electronic devices, and in particular to a wind-liquid hybrid cooling cabinet. Background Technology

[0002] Currently, heat dissipation in communication equipment rooms and data centers is mostly achieved through air conditioning within the rooms. However, room-level equipment rooms have large spaces and low temperature requirements, and the energy consumption of air conditioning running continuously even exceeds the power consumption of communication equipment, resulting in a PUE (Power Usage Effectiveness) value of over 2.0. Therefore, how to reduce heat dissipation energy consumption and improve energy efficiency has become an urgent problem to be solved.

[0003] In the prior art, such as the Chinese utility model patent with patent number CN217088497U disclosed on July 29, 2022, a supercomputer liquid cooling cabinet. This supercomputer liquid cooling uses liquid refrigerant as the cooling medium. The liquid refrigerant evaporates into a gaseous state when heated. The heat absorption of the refrigerant during evaporation is used to dissipate heat from the server surface. After evaporation, the refrigerant rises to the liquefaction device in the cover and is liquefied before flowing back into the cabinet. It can be reused and reduces the waste of resources.

[0004] However, when the liquid cooler is actually cooling, the coolant will carry heat to the upper part of the electronic equipment as it flows from the bottom to the top, resulting in uneven cooling of the electronic equipment, that is, the temperature at the top is higher than the temperature at the bottom, which is a problem of uneven heat dissipation. Utility Model Content

[0023] like Figures 1 to 8 The air-liquid mixing cooling cabinet shown includes cabinet 1, specifically as follows: Figure 2 As shown in the embodiment of this utility model, the cabinet 1 has a receiving cavity 11 inside, and the cabinet 1 also has a front door 12. When the front door 12 is opened, the receiving cavity 11 is connected to the outside. With this arrangement, electronic devices can be conveniently placed in the receiving cavity 11. Specifically, such as Figure 2 As shown in the embodiment of the utility model, the receiving cavity 11 includes a gas-liquid mixing cavity 13 for forming a saturated gas mixture, a heat source cavity 14 for placing electronic equipment, and a coolant recovery cavity 15 communicating with the heat source cavity 14; please continue to refer to Figure 2 In this embodiment of the invention, the receiving cavity 11 further includes an air supply mechanism 2 for delivering the saturated mixed gas in the air-liquid mixing cavity 13 into the heat source cavity 14, and the coolant recovery cavity 15 further includes a heat exchange mechanism 3, wherein the saturated mixed gas flows laterally within the heat source cavity 14. It should be noted that the air supply mechanism 2 and the heat exchange mechanism 3 can take various forms, and those skilled in the art can select according to their needs.

[0024] In this embodiment of the invention, when specifically cooling the electronic device, the saturated mixed gas in the air-liquid mixing chamber 13 is laterally fed into the heat source chamber 14 via the air supply mechanism 2. This saturated mixed gas can be a fluorinated liquid atomized with air. As the saturated mixed gas passes laterally through the electronic device, it carries away heat. Upon entering the heat source chamber 14, some of the atomized fluorinated liquid vaporizes, carrying away the heat from the electronic device. It then forms a liquid on the heat exchange mechanism 3 and flows back to the coolant recovery chamber 15. The liquid in the coolant recovery chamber 15 is cooled by external cooling before re-entering the air-liquid mixing chamber 13 to form a saturated mixed gas. It should be noted that in this embodiment of the invention, the fluorinated liquid is easily liquefied due to its high boiling point; the coolant is the fluorinated liquid. Of course, those skilled in the art can choose other coolants as needed. In this embodiment of the invention, a fluorinated liquid storage tank can be provided at the bottom of the coolant recovery chamber 15, which, after being cooled by external equipment, recirculates back into the air-liquid mixing chamber 13.

[0025] In the above embodiment, by placing the electronic device in the heat source cavity 14, the saturated mixed gas in the air-liquid mixing cavity 13 is blown into the heat source cavity 14 by the air supply mechanism 2. After the saturated mixed gas carries away the heat of the electronic device, it undergoes heat exchange. Compared with the prior art, the saturated mixed gas in this embodiment flows laterally in the heat source cavity 14, thereby improving the uniformity of heat dissipation and improving the cooling effect on the electronic device.

[0026] Based on the above embodiments, in the embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the receiving cavity 11 has a vertically arranged partition 16, which separates the air-liquid mixing cavity 13 from the heat source cavity 14 in the width direction of the receiving cavity 11.

With this arrangement, when the first fan 22 operates, the saturated mixed gas in the air-liquid mixing chamber 13 enters the pipe body 21 from the air-liquid mixing chamber 13 through the air inlet 21a, and then is sent into the heat source chamber 14 through the air outlet 21b. Since the pipe body 21 is located at the front end of the air-liquid mixing chamber 13, thus... Figure 2 As shown in the top view, the saturated mixed gas that is fed into the heat source cavity 14 also enters from the front end of the heat source cavity 14. This structural form can ensure that the temperature of the saturated mixed gas entering the heat source cavity 14 is the lowest, which is conducive to circulating heat dissipation.

[0031] Furthermore, in embodiments of this utility model, in order to further accelerate the heat exchange efficiency of the plate heat exchanger 33, such as... Figure 7As shown, a second fan 35, which communicates with the interior of the housing 31, is also provided on the side of the housing 31 opposite to the mesh plate 32. The second fan 35 can dissipate some of the heat from the plate heat exchanger 33 from the housing 31, thereby improving the heat dissipation efficiency.
