[0026] A specific embodiment of the present invention provides a condenser, including a heat exchanger 1, a water tank 2, a water pump 3 and a nozzle 4, a nozzle 6 is provided on the nozzle 4, the water pump 3 can be placed outside the water tank 2 or inside the water tank 2 according to different types, after the water pump 3 is started, it absorbs water in the water tank 2, the output port of the water pump 3 is connected to the nozzle 4, and the water is transported to the nozzle 4 after being pressurized, and finally sprayed out through the nozzle 6 in the form of water mist. The nozzle 6 faces the side of the heat exchanger 1. Furthermore, a wet film 5 is provided 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 wet film 5 through the nozzle 6.

[0027] Different operation modes are adopted according to the outdoor temperature. When the outdoor temperature is low, the fluorine pump mode is operated in winter, and the compressor stops running; when the outdoor temperature is high, the evaporative cooling mode is operated in summer, and the water in the water tank 2 is pressurized by the water pump 3 and enters the nozzle 4, and forms high-pressure micro-mist through the nozzle 6, which is sprayed onto the wet film 5. The air passes through the wet film 5 for evaporative cooling. After the air temperature is reduced, it exchanges heat with the heat exchanger 1, and the condensation heat is discharged through the fan. The surface area of ​​the wet film 5 is large, so that the water and the air are fully in contact, the cooling effect is improved, the evaporation efficiency is high, and the energy saving effect is better. In addition, the wet film 5 protects the heat exchanger 1, avoids direct contact between water and the heat exchanger 1, avoids corrosion of the fins, improves the reliability and safety of the equipment, avoids damage to the heat exchanger 1, and ensures the normal use of the heat exchanger 1. There is no need to frequently repair and replace the heat exchanger 1 to avoid greater losses.

[0028] Specifically, the heat exchanger 1 includes two plates arranged opposite to each other, the plates are arranged obliquely and the bottoms are close to each other, that is, the heat exchanger 1 is a V-shaped structure with the opening upward, and the fan is arranged above the V-shaped structure to allow air to simultaneously pass through the two plates of the heat exchanger 1. The sides of the two plates facing each other are the inner sides, and the sides of the two plates facing away from each other are the outer sides. The nozzles 6 face the outer sides of the plates, so the wet films 5 are arranged on the outer sides of the two plates.

[0029] Furthermore, since wet films 5 are provided on both sides of the heat exchanger 1, it is necessary to provide nozzles 4 on both sides, facing the wet films 5 on both sides respectively, and connect the outlet of the water pump 3 to the outlet pipe 7, and connect the two groups of nozzles 4 at the end of the outlet pipe 7. The outlet pipe 7 is divided into two ways to supply water to the left and right heat exchanger 1 plates according to the layout of the heat exchanger 1. The water tank 2 is connected to the water inlet pipe 8, and filters 9 are provided on the water inlet pipe 8 and the outlet pipe 7. The water tank 2 can be replenished with water through the water inlet pipe 8. The filter 9 on the water inlet pipe 8 ensures that the water quality entering the water tank 2 meets the requirements.

During operation, when spraying is required, the water pump 3 is controlled to start, and the switch valve on the water outlet pipe 7 is opened, and the water level detector detects the water level in the water tank 2 in real time. When the water level is too low, the switch valve on the water inlet pipe 8 is controlled to open to replenish water for the water tank 2. The pressure detector detects the outlet water pressure in real time. When the pressure is too high, the switch valve on the pressure relief pipe is opened to release the pressure. When the water tank 2 needs to be cleaned, the switch valve on the drain pipe is controlled to open to discharge the water in the water tank 2. The layout of each pipe fitting can also be adjusted according to the situation, which is within the protection scope of the present invention.

[0031] In the first embodiment, the nozzle 4 on each side includes a plurality of transverse tubes, which are arranged in sequence from top to bottom, and a plurality of nozzles 6 are installed in sequence on each transverse tube. The plane where the plurality of transverse tubes on the same side are located is inclined to match the outer inclined surface of the heat exchanger 1. A plurality of vertical tubes are provided at the same time, and the vertical tubes connect the plurality of transverse tubes, so that water can enter each transverse tube. The head end and the tail end of the transverse tube are defined according to the direction of the water flow in each transverse tube, and the water flow in the transverse tube flows from the head end to the tail end during spraying. Specifically, the plurality of transverse tubes are connected in series in sequence, that is, the head end and the tail end of the plurality of transverse tubes on the same side are arranged alternately, so that the lower end of the vertical tube is connected to the tail end of the transverse tube below, and the upper end of the vertical tube is connected to the head end of the transverse tube above. Since the head end and the tail end of the transverse tube are arranged alternately, the plurality of vertical tubes are arranged alternately at both ends of the transverse tube, so as to form a nozzle 4 with a serpentine coil structure. The water output by the water pump 3 needs to pass through the transverse tube below before it can flow to the transverse tube above. The structure is simple, and an integrated bending molding can be adopted to reduce the cost.

[0032] Preferably, the transverse tubes are arranged obliquely, and the head end of the transverse tubes is lower than the tail end. In this embodiment, among the multiple transverse tubes on the same side, the inclination directions of two adjacent transverse tubes are opposite, ensuring that the head end of each transverse tube is lower than the tail end. The transverse tubes are inclined downward toward the water inlet direction to ensure that the water in the nozzle 4 can flow back to the water tank 2 by gravity when the spray operation is stopped, preventing the tube from freezing and bursting when the temperature drops.

[0033] In the second embodiment, the nozzle 4 on each side includes a plurality of transverse tubes, which are arranged in sequence from top to bottom, and a plurality of nozzles 6 are installed in sequence on each transverse tube.

A plurality of vertical tubes are provided at the same time, and the vertical tubes connect the plurality of transverse tubes, so that water can enter each transverse tube. The head end and the tail end of the transverse tube are defined according to the direction of the water flow in each transverse tube, and the water flow in the transverse tube flows from the head end to the tail end during spraying. Specifically, the plurality of transverse tubes are connected in parallel in sequence, that is, the head end and the tail end of the plurality of transverse tubes on the same side are oriented in the same direction, so that the lower end of the vertical tube is connected to the head end of the transverse tube below, and the upper end of the vertical tube is connected to the head end of the transverse tube above. Since the head end and the tail end of the transverse tube are oriented in the same direction, the plurality of vertical tubes are arranged at the head end of the transverse tube, forming a nozzle 4 with a comb structure. The water output by the water pump 3 can enter each transverse tube at the same time after each vertical tube is filled. Improve reliability. When one transverse pipe is blocked, other transverse pipes can still work normally, avoiding a single failure affecting all nozzles 4.

[0034] Preferably, the transverse tubes are arranged obliquely, and the head end of the transverse tubes is lower than the tail end. In this embodiment, among the multiple transverse tubes on the same side, the two adjacent transverse tubes have the same inclination direction, ensuring that the head end of each transverse tube is lower than the tail end. The transverse tubes are inclined downward toward the water inlet direction, ensuring that the water in the nozzle 4 can flow back to the water tank 2 by gravity when the spray operation is stopped, preventing the tube from freezing and bursting when the temperature drops.

[0035] In the third embodiment, the nozzle 4 on each side includes a plurality of transverse tubes, which are arranged in sequence from top to bottom, and a plurality of nozzles 6 are installed in sequence on each transverse tube.

A plurality of vertical tubes are provided at the same time, and the vertical tubes connect each transverse tube, so that water can enter each transverse tube. Specifically, the plurality of transverse tubes are connected in parallel in sequence, so that the upper end and the lower end of the vertical tube are respectively connected to the middle part of the adjacent transverse tube, forming a tree-shaped nozzle 4. After each vertical tube is filled, the water output by the water pump 3 can enter the middle part of each transverse tube at the same time, and then flow to the two ends of the transverse tube. To improve reliability, when a certain transverse tube is blocked, other transverse tubes can also work normally, avoiding a single fault from affecting all the nozzles 4.

[0036] Preferably, the transverse tubes are arranged obliquely, and the head end of the transverse tube is lower than the tail end. In this embodiment, among the multiple transverse tubes on the same side, each transverse tube is V-shaped, low in the middle and high at both ends, and the two adjacent transverse tubes are inclined in the same direction to ensure that the head end of each transverse tube is lower than the tail end. The transverse tubes are inclined downward toward the water inlet direction to ensure that the water in the nozzle 4 can flow back to the water tank 2 by gravity when the spray operation is stopped, to prevent freezing and tube bursting when the temperature drops.
