The nozzle 6 faces the side of the heat exchanger 1. Further, a wet film 5 is arranged on the side of the heat exchanger 1, the wet film 5 covers and shields the side of the heat exchanger 1, and the nozzle 6 faces the wet film 5, and sprays the mist to the wet film 5 through the nozzle 6.

[0027] According to different operating modes according to outdoor temperature, when the outdoor temperature is low, i.e. in winter, the fluorine pump mode is run, and the compressor stops running; when the outdoor temperature is high, i.e. in summer, the evaporative cooling mode is run, the water in the water tank 2 is pressurized by the water pump 3 and then enters the spray pipe 4, high-pressure mist is formed through the nozzle 6, and is sprayed onto the wet film 5, air passes through the wet film 5 to undergo evaporative cooling, the air temperature is reduced, and then the air exchanges heat with the heat exchanger 1, and the condensation heat is discharged by the fan.

[0028] Specifically, the heat exchanger 1 comprises two oppositely arranged plate members, which are arranged obliquely and have their bottoms close to each other, i.e. the heat exchanger 1 has a V-shaped structure with an opening upward, and the fan is arranged above the V-shaped structure to make the air pass through the two plate members of the heat exchanger 1 simultaneously. The opposite sides of the two plate members are inner sides, and the sides of the two plate members away from each other are outer sides, and the nozzles 6 are directed toward the outer sides of the plate members, so the wet film 5 is arranged on the outer sides of the two plate members.

[0029] Further, since the heat exchanger 1 is provided with the wet film 5 on both sides, it is necessary to arrange two groups of nozzles 4 directed toward the wet films 5 on the two sides, and the outlet pipe 7 is connected to the output port of the water pump 3 and connected to the two groups of nozzles 4 at the ends. The outlet pipe 7 is divided into two paths according to the layout of the heat exchanger 1 to supply water to the plate members of the heat exchanger 1 on the left and right sides. The water tank 2 is connected with the inlet pipe 8, and the filter 9 is arranged on the inlet pipe 8 and the outlet pipe 7, so that the water tank 2 can be replenished through the inlet pipe 8, and the filter 9 on the inlet pipe 8 ensures that the water entering the water tank 2 meets the requirements, and at the same time, the filter 9 on the outlet pipe 7 ensures that the water for spraying meets the requirements.

During operation, when spraying is needed, the water pump 3 is started, and the on-off valve on the outlet pipe 7 is opened, the water level detector detects the water level in the water tank 2 in real time, when the water level is too low, the on-off valve on the inlet pipe 8 is opened to replenish the water tank 2, the pressure detector detects the outlet pressure in real time, when the pressure is too high, the on-off valve on the pressure relief pipe is opened to release pressure, when the water tank 2 needs to be cleaned, the on-off valve on the drain pipe is opened to drain the water in the water tank 2. The layout of each pipe can also be adjusted according to the situation, which is within the protection scope of the present application.

[0031] In the first embodiment, each side of the spray pipe 4 includes a plurality of transverse pipes arranged in sequence from top to bottom, a plurality of nozzles 6 are installed in sequence on each transverse pipe, the plane where the plurality of transverse pipes on the same side is arranged obliquely, matched with the outer inclined surface of the heat exchanger 1, and a plurality of vertical pipes are arranged at the same time, the vertical pipes connect each transverse pipe, so that water can enter each transverse pipe. The first end and the last end of the transverse pipe are defined according to the direction of the water flow in the transverse pipe, and the water flow in the transverse pipe flows from the first end to the last end during spraying. Specifically, the plurality of transverse pipes are connected in sequence, that is, the first end and the last end of the plurality of transverse pipes on the same side are arranged alternately, so that the lower end of the vertical pipe is connected to the last end of the lower transverse pipe, and the upper end of the vertical pipe is connected to the first end of the upper transverse pipe. Due to the alternate arrangement of the first end and the last end of the transverse pipe, the plurality of vertical pipes are arranged alternately at the two ends of the transverse pipe, forming a spray pipe 4 with a serpentine coil structure. The water output by the water pump 3 needs to pass through the lower transverse pipe first before flowing to the upper transverse pipe. The structure is simple and can be formed by one-piece bending, reducing the cost.

[0032] Preferably, the transverse pipes are arranged obliquely, and the first end of the transverse pipe is lower than the last end. In this embodiment, the oblique directions of the two adjacent transverse pipes among the plurality of transverse pipes on the same side are opposite, so that the first end of each transverse pipe is lower than the last end. The transverse pipe is inclined downward in the water inlet direction, so that when the spraying operation is stopped, the water in the spray pipe 4 can flow back into the water tank 2 by gravity, preventing freezing caused by temperature reduction from causing pipe explosion.

[0033] In the second embodiment, each side of the spray pipe 4 includes a plurality of transverse pipes arranged in sequence from top to bottom, a plurality of nozzles 6 are installed in sequence on each transverse pipe, the plane where the plurality of transverse pipes on the same side is arranged obliquely, matched with the outer inclined surface of the heat exchanger 1, and a plurality of vertical pipes are arranged at the same time, the vertical pipes connect each transverse pipe, so that water can enter each transverse pipe. The first end and the last end of the transverse pipe are defined according to the direction of the water flow in the transverse pipe, and the water flow in the transverse pipe flows from the first end to the last end during spraying. Specifically, the plurality of transverse pipes are connected in parallel, that is, the first end and the last end of the plurality of transverse pipes on the same side are consistent in direction, so that the lower end of the vertical pipe is connected to the first end of the lower transverse pipe, and the upper end of the vertical pipe is connected to the first end of the upper transverse pipe. Due to the consistent direction of the first end and the last end of the transverse pipe, the plurality of vertical pipes are arranged at the first end of the transverse pipe, forming a spray pipe 4 with a comb structure. After the vertical pipes are filled with water, the water output by the water pump 3 can enter each transverse pipe at the same time. The reliability is improved, and other transverse pipes can also work normally when a certain transverse pipe is blocked, avoiding the influence of a single fault on all spray pipes 4.

The water output by the water pump 3 can enter the middle part of each lateral tube after filling each vertical tube, and then flow to both ends of the lateral tube. The reliability is improved, and when one lateral tube is blocked, the other lateral tubes can also work normally, avoiding the influence of a single fault on the entire spray tube 4.

In this embodiment, the adjacent two lateral tubes of the plurality of lateral tubes on the same side are arranged to be inclined in the same direction, so that the leading end of each lateral tube is lower than the trailing end. The lateral tubes are inclined downward toward the water inlet direction, so that when the spraying operation is stopped, the water in the spray tube 4 can flow back into the water tank 2 by gravity, preventing the pipe from being frozen and burst due to temperature reduction.
