Description

Technical Field

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

[0002] A wind-liquid mixing cooler refers to a coolant that, under the pressure of a high-pressure pump, forms a saturated mixed gas inside the cooler. The gas is drawn into the communication equipment by its own fan, carrying away heat, and then exchanges heat with the heat exchange plate to form a liquid that flows back to the coolant area.

[0003] In related technologies, fluorinated liquids have become the main choice for coolants in air-liquid mixed cooling cabinets due to their electrical insulation, non-flammability, chemical stability, and high phase change heat dissipation efficiency. However, although fluorinated liquids have great technical advantages, once a fluorinated liquid leaks, it may disrupt the cooling cycle and increase maintenance costs. On the other hand, it will also affect the air quality of the computer room.

[0004] Therefore, how to control the leakage of coolant in the fan mixing cabinet has become an urgent technical problem to be solved. Utility Model Content

[0005] In view of at least one of the above technical problems, the present invention provides a wind-liquid hybrid cooling base station, which adopts structural improvements to control coolant leakage.

[0006] According to a first aspect of the present invention, a wind-liquid hybrid cooling base station is provided, comprising: A shipping container having a sealed space inside; A wind-liquid mixing cooling cabinet is installed in the sealed space. The wind-liquid mixing cooling cabinet includes a cabinet body, a wind-liquid mixing chamber installed in the cabinet body, a heat source chamber for placing electronic equipment, and a heat exchange chamber connected to the rear end of the heat source chamber. The primary side equipment includes a coolant distributor connected to the heat exchange chamber and a heat dissipation tower connected to the coolant distributor; The container is equipped with an exhaust fan, which is used to maintain a negative pressure within the enclosed space.

[0007] Furthermore, the exhaust fan maintains a negative pressure of 100 to 300 Pa within the enclosed space.

[0008] Furthermore, the exhaust fan is connected to a gas collector for the condensation and recovery of the gas.

[0009] Furthermore, the cabinet also has a front door, which is hinged to the cabinet and is positioned directly opposite the opening of the heat source cavity when closed.

[0010] Furthermore, the air-liquid mixing chamber is arranged parallel to the side of the heat source chamber, and the front end of the air-liquid mixing chamber is provided with an air supply fan for supplying air toward the front end of the heat source chamber.

[0011] Furthermore, a spray controller is also fixed on the cabinet. One end of the spray controller is connected to the coolant distributor, and the other end is connected to the air-liquid mixing chamber inside the cabinet. The spray controller is configured to stop spraying when the front door is opened and to start spraying when the front door is closed.

[0012] Furthermore, a backup air conditioner is installed on the inner wall of the container, which is configured to turn on when the front door is opened and turn off when the front door is closed.

[0013] Furthermore, a rear door is provided on the side of the cabinet opposite to the front door, and the heat exchange chamber is hinged to the side of the heat source chamber opposite to the front door.

[0014] The beneficial effects of this utility model are as follows: This utility model places the air-liquid mixing cooling cabinet inside a container with a sealed space, and connects the air-liquid mixing cooling cabinet to the primary side equipment to achieve heat dissipation for the electronic equipment in the heat source cavity. By installing an exhaust fan on the container, the container is kept under negative pressure. The negative pressure setting ensures that the coolant is confined in the sealed space and will not overflow. Furthermore, the exhaust fan can achieve directional collection, monitoring, and condensation recovery of leaked gas. Attached Figure Description

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] like Figures 1 to 5 The air-liquid hybrid cooling base station shown includes a container 1, an air-liquid hybrid cooling cabinet 2, and primary side equipment 3, as detailed below. Figure 1 and Figure 2 As shown in the embodiment of this utility model, the container 1 has a sealed space 11, that is, after the door of the container 1 is closed, its interior is in a sealed state; the air-liquid mixing cooling cabinet 2 is disposed in the sealed space 11, and the air-liquid mixing cooling cabinet 2 includes a cabinet body 21, an air-liquid mixing chamber 22 disposed in the cabinet body 21, a heat source chamber 23 for placing electronic equipment, and a heat exchange chamber 24 connected to the rear end of the heat source chamber 23; in specific operation, atomized coolant is injected from the air-liquid mixing chamber 22, the coolant mixes with air to form a gas, the gas enters the heat source chamber 23 from the air-liquid mixing chamber 22 to cool the electronic equipment therein, and the heat is carried away and then heat exchange occurs on the heat exchange chamber 24, the gas liquefies again to form liquid and accumulates in the heat exchange chamber, and then forms a cycle through the primary side device 3; in the embodiment of this utility model, as Figure 2 As shown, the primary side device 3 includes a coolant distributor 31 connected to the heat exchange chamber 24 and a heat dissipation tower 32 connected to the coolant distributor 31. The coolant distributor injects the coolant cooled by the heat dissipation tower 32 into the air-liquid mixing chamber 22 through a nozzle. Then, it discharges the coolant accumulated in the heat exchange chamber 24 and transports it to the heat dissipation tower 32 for heat dissipation and cooling before injecting it back into the air-liquid mixing chamber 22 for circulating cooling.

[0022] In the above embodiment, the container 1 is equipped with an exhaust fan, which is used to maintain a negative pressure within the sealed space 11. By installing the exhaust fan, a negative pressure is created within the sealed container 1, thereby confining any potentially leaked coolant, such as fluorinated gas, inside the container 1 and preventing its diffusion into the external space. It should be noted that the exhaust fan is connected via piping to a dedicated device for collecting fluorinated liquid. The collection of fluorinated liquid is existing technology and will not be described in detail here.

[0023] In the above embodiment, by placing the air-liquid mixing cooling cabinet 2 inside the container 1 with a sealed space 11, and connecting the air-liquid mixing cooling cabinet 2 to the primary side device 3, heat dissipation is achieved for the electronic equipment in the heat source cavity 23. By installing an exhaust fan on the container 1, a negative pressure is maintained inside the container 1. By setting the negative pressure, the coolant is confined in the sealed space and will not overflow. Furthermore, the exhaust fan can be used to collect, monitor, and condense and recover leaked gas.

[0024] In some embodiments of this invention, the exhaust fan maintains a negative pressure of 100 to 300 Pa within the sealed space 11. It should be noted that in these embodiments, 100 to 300 Pa includes two endpoints; the setting of this parameter is crucial because excessively low negative pressure cannot effectively suppress gas leakage, while excessively high pressure may adversely affect equipment operation. By controlling the pressure between 100 and 300 Pa, a balance is achieved between preventing the diffusion of fluorinated liquid gas and maintaining normal equipment operation. In some embodiments of this invention, the exhaust fan is connected to a gas collector for gas condensation and recovery. This gas collector can be a condensation and recovery device, which can convert leaked fluorinated liquid into liquid for recovery, thus forming a complete closed-loop protection system. The condensation and recovery of fluorinated liquid is a conventional technique in this field, and its specific structure and principle will not be elaborated here.

[0025] Please continue to refer to Figure 4In an embodiment of this utility model, the cabinet 21 also has a front door 21a, which is hinged to the cabinet 21 and faces the opening of the heat source cavity 23 when closed. This structure allows electronic devices to be conveniently placed inside the heat source cavity 23; that is, when the front door 21a is open, the opening of the heat source cavity 23 faces the front door 21a, allowing the electronic device to be directly placed inside. In an embodiment of this utility model, as... Figure 3 and Figure 4 As shown, the air-liquid mixing chamber 22 is arranged parallel to the side of the heat source chamber 23, and an air supply fan 23a for supplying air towards the front of the heat source chamber 23 is provided at the front end of the air-liquid mixing chamber 22. Here, the side can be as follows: Figure 3 The two sides in the width direction shown can also be one side. With the air supply fan 23a, the saturated mixed gas in the air-liquid mixing chamber 22 can be transported to the heat source chamber 23. In the heat source chamber 23, the saturated mixed gas is drawn in and discharged to the heat exchange chamber 24 by the fan built into the electronic device. In the embodiment of this utility model, the heat exchange chamber 24 has a heat exchange structure such as a plate heat exchanger, so that the saturated mixed gas that has taken away heat will transfer heat on the heat exchanger and change from gaseous state to liquid state, and fall down along the outer wall of the heat exchanger into the coolant storage tank at the bottom of the heat exchange chamber 24.

[0026] Please continue to refer to Figure 4 In this embodiment of the invention, a spray controller 25 is also fixed on the cabinet 21. One end of the spray controller 25 is connected to the coolant distributor 31, and the other end is connected to the air-liquid mixing chamber 22 inside the cabinet 21. The spray controller 25 is configured to stop spraying when the front door 21a is opened and to start spraying when the front door 21a is closed. The spray controller 25 can be a solenoid valve, and the opening and closing of the valve controls the spraying. The detection of the opening and closing of the front door 21a can be achieved using a photoelectric sensor or other existing sensors such as stroke sensors. This structural design reduces the direct leakage of fluorinated liquid into the environment after atomization, preventing the spread of coolant.

[0027] Furthermore, in embodiments of this invention, considering that the spray is forced to stop when the front door 21a is opened, and if other cooling methods are lacking, the electronic equipment inside the heat source cavity 23 may be damaged due to overheating, such as... Figure 2 As shown in some embodiments of this invention, a backup air conditioner 26 is also installed on the inner wall of the container 1. The backup air conditioner 26 is configured to turn on when the front door 21a is opened and turn off when the front door 21a is closed. The backup air conditioner 26 ensures that cooling measures are still available during maintenance, thereby ensuring that the equipment can work stably under different operating conditions. This structural form achieves complementarity between the cooling system and the traditional air conditioner, improving the overall robustness of the system.

[0028] In addition, please continue to refer to Figure 5 In this embodiment of the invention, a rear door 21b is also provided on the side of the cabinet 21 opposite to the front door 21a, and the heat exchange chamber 24 is hinged to the side of the heat source chamber 23 opposite to the front door 21a. This structure improves the convenience of maintaining the heat exchanger inside the heat exchange chamber 24; only the rear door 21b needs to be opened, and then the heat exchange chamber 24 can also be opened, thus facilitating maintenance of the heat exchange chamber 24. This double-door design greatly enhances operational flexibility.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
