[0004] The purpose of the utility model is achieved in this way:

[0005] A cooling fan for refrigeration, comprising an air outlet body, a water tank, and a condensing assembly arranged between the air outlet body and the water tank. The air outlet body is provided with more than two water curtain assemblies arranged in different positions and directions and cooperating with an evaporator to cool hot air. By setting the working conditions of each water curtain assembly, the cooling fan has a first working mode and a second working mode.

[0006] The air cooler is in the first working mode, and each water curtain assembly cooperates with the evaporator to cool the hot air; the air cooler is in the second working mode, and one of the water curtain assemblies cooperates with the evaporator to cool the hot air;

[0007] In the first working mode and the second working mode, the liquid in the water tank passes through the water curtain assembly and enters the condensation assembly, and the liquid condenses the assembly and returns to the water tank after heat exchange; wherein the condensation assembly includes a first condensation tube and a second condensation tube arranged in an upper and lower arrangement, and the liquid passing through the water curtain assembly exchanges heat with the first condensation tube and the second condensation tube in turn.

[0008] By setting up a double-layer condenser (a first condenser and a second condenser), the condensing power is increased, which is suitable for higher-power refrigeration and improves the heat exchange efficiency and heat exchange area.

A drainage hole connected to the drainage cavity is provided on the support plate. Even if water enters the electrical cavity in the installation cavity, the liquid can enter the drainage cavity through the drainage hole to prevent water accumulation in the electrical cavity. In addition, the elastic support at the bottom of the compressor is suspended on the support plate, which plays a shock-absorbing role when the compressor is working. Even if water enters the electrical cavity, the bottom of the compressor will not be immediately submerged.

[0012] The air outlet body includes a frame and a panel. The frame is provided with a receiving cavity for receiving the water curtain assembly. The panel is buckled on the frame so that the water curtain assembly is limitedly installed on the receiving cavity.

The first water pump diverts the liquid into the three water curtain assemblies through the diversion pipe of the three-way mechanism, which is beneficial to improve the heat dissipation effect and thus improve the refrigeration power.

[0024] In addition, a first water pump and a second water pump are provided, and starting the corresponding first water pump and second water pump can control the operation of different water curtain components. When the heat dissipation requirement is small, only one water curtain component is started to work, thereby effectively reducing noise.

[0025] The condensation assembly also includes a first water receiving tray for receiving the first condensation tube, and a second water receiving tray for receiving the second condensation tube, the first water receiving tray is supported on the second water receiving tray, and the second water receiving tray is supported on the water tank; the air outlet body is supported on the first water receiving tray, and a condensation tube cover is provided on the top of the first water receiving tray, the first condensation tube is encapsulated on the first water receiving tray through the condensation tube cover, and the second condensation tube is encapsulated on the second water receiving tray through the first condensation tube;
