[0028] In this embodiment, the heat exchange device is an existing fin heat exchanger, and a conventional fluid channel is provided in the fin heat exchanger. The fluid channel is connected to a tap water pipe and water is continuously introduced into the fluid channel.

[0029] In this embodiment, the coolant fluid formed by the wind-mist mixed gas contacting the fin heat exchanger is returned to the coolant storage chamber through the porous plate 8. Generally, the porous plate means that the plate below the fin heat exchanger is a porous structure, not an additional arrangement.

[0030] The atomization mechanism includes a coolant pipe 601, 36 atomization nozzles 602, and a high-pressure pump 603; the atomization nozzle is arranged on the coolant pipe; the mist outlet direction of the atomization nozzle faces the electronic equipment placement rack; the high-pressure pump is connected to the coolant pipe and the coolant storage chamber.

In the utility model, the water flowing out of the fluid channel of the fin heat exchanger can also be circulated through a water pipe or a conventional heat dissipation tower under a conventional environment to reach the required temperature. There is no need to set up a cooling system and no cooling energy consumption. The specific water circulation method is selected according to actual needs. Embodiment 2

[0033] On the basis of the first embodiment, the difference of this embodiment is that an air extraction cavity 11 is provided at the rear of the cabinet body, which is connected to the inside of the cabinet body, and the air extraction cavity is surrounded by a mounting plate; a second fan group 12 is provided in the air extraction cavity, and the third fan group includes 9 fans; a pipe interface 13 is provided in the air extraction cavity, and the rest is the same, such as Figures 5 to 8 When it is necessary to inspect or replace the electronic equipment, the cabinet is opened, the cooling of the electronic equipment is stopped, and the second fan group starts to run to recover the coolant in the wind-mist mixed gas and reduce the leakage of the coolant. Embodiment 3

[0034] Based on the first embodiment, the difference of this embodiment is that a third fan group 14 is provided on the side of the heat exchange device away from the electronic equipment placement rack, and the rest is the same, such as Fig. 9 The third fan group includes 9 fans, which are used to accelerate the flow of the wind-mist mixed gas and remove the heat generated by the operation of the electronic equipment more quickly.

[0035] The main working process of the utility model wind-mist mixed liquid refrigerator is:

[0036] (1) The BBU equipment is placed vertically on an electronic equipment rack. The water first introduced into the fluid channel of the heat exchange device is connected from the tap water pipe. The water introduced later is the water that is discharged and then circulated through the water pipe under normal conditions;

[0037] (2) The high-pressure pump runs, the coolant enters the coolant pipe, and is broken up by the atomizing nozzle to form atomized coolant;

[0038] (3) In the air-fog mixing chamber, the atomized coolant mixes with the air to form an air-fog mixed gas. The fan module of the BBU equipment faces the air-fog mixing chamber, driving the air-fog mixed gas to flow through the electronic equipment. The third fan group accelerates the flow of the air-fog mixed gas.

[0039] (4) The wind-mist mixed gas flowing out of the electronic equipment contacts the heat exchange device, atomizing the coolant mist to form a coolant fluid, which is separated from the air and enters the coolant storage chamber through the porous plate;

[0040] (5) The first fan group generates airflow, driving the air separated from the coolant through the air circulation chamber into the wind-fog mixing chamber, and then forms a wind-fog mixed gas with the atomized coolant.

[0041] Furthermore, when the cabinet door is opened, the cooling of the BBU equipment stops, the second fan group extracts air, and the coolant in the wind-mist mixed gas is discharged from the cabinet through an external pipe.

[0042] Application Examples

[0043] PUE (Power Usage Effectiveness) is an indicator for evaluating the power usage efficiency of a data center. The PUE value refers to the ratio of all energy consumed by a data center to the energy consumed by communication loads. The total energy consumption of a data center includes the energy consumption of communication equipment and the energy consumption of systems such as cooling and power distribution. The closer the PUE value is to 1, the less energy is consumed by non-communication equipment, that is, the better the energy efficiency level and the higher the degree of greenness.

[0044] BBU devices vary in size and power consumption, making them difficult to standardize. The commonly used method in current production and considered to be more effective is to use air conditioning to cool the entire communication room, with a PUE value of over 2.0.

[0045] The wind-mist mixed liquid refrigerator of the first embodiment is used to replace the existing air-conditioning room cooling method to cool the BBU equipment, achieving a cooling effect similar to that of the air-conditioning room cooling, and the PUE value is below 1.35.

[0046] The above-described embodiments are only preferred embodiments of the present invention. It should be noted that a person skilled in the art may make several modifications and improvements without departing from the principles of the present invention, and these modifications and improvements should also be considered to fall within the scope of protection of the present invention.
