[0024] Example 1

[0025] like Figures 1 to 7 As shown;

[0026] A plate-shell evaporative condensing device comprises a box body 1 and a cover plate 3 installed on the top of the box body 1, a water tank 4 is fixed at the bottom of the box body 1, a circulating water pump 5 is embedded in the side of the water tank 4, the input end of the circulating water pump 5 extends to the bottom side of the water tank 4, the output end of the circulating water pump 5 is connected to a hose 6, the other end of the hose 6 is connected to the cover plate 3, a plurality of uniformly arranged condensing plates 2 are inserted into the inner side of the box body 1, a disc-shaped coil 21 is embedded in the surface of the condensing plate 2, both ends of the coil 21 pass through the top of the condensing plate 2 and extend to the outside of the cover plate 3, and the exposed ends of two adjacent coils 21 are inserted with connecting pipes 7, and a spray head 8 is installed at the position of the inner side of the cover plate 3 corresponding to the condensing plate 2, and the spray head 8 is connected to the hose 6;

[0027] In the present embodiment: When the user uses the present invention, an appropriate number of condensing plates 2 can be selected according to the refrigerant condition of the refrigeration equipment, and the condensing plates 2 can be connected in series through the connecting pipe 7 to change the stroke of the refrigerant heat exchange operation. The refrigerant pipeline is connected to the exposed end of the coil 21, and then the circulating water pump 5 is started. When the refrigerant enters the box body 1, the circulating water pump 5 transports the spray water to the spray head 8 through the hose 6. The spray head 8 sprays on both sides of the condensing plate 2. The spray water forms a water film on the surface of the condensing plate 2 and exchanges heat with the refrigerant in the coil 21. The spray water is in a flowing state, which can avoid the formation of scale on the surface of the condensing plate 2.

[0028] More specifically:

[0029] In an optional embodiment, a through hole is opened on the surface of the cover plate 3 at a position corresponding to the coil 21, and a water retaining ring 31 is provided around the through hole.

[0030] In this embodiment: through this design, the water retaining ring 31 can prevent the spray water of the spray head 8 from splashing out from the box body 1 when spraying.

[0031] Going further:

[0032] In an optional embodiment, a plurality of heat exchange fins 22 are formed on both side surfaces of the condensation plate 2 .

[0033] In this embodiment: through this design, the heat exchange fins 22 and the spray water can maintain a larger contact area, thereby improving the heat exchange efficiency and facilitating the cooling by refrigerant spraying.

[0034] Going further:

[0035] In an optional embodiment, ventilation holes 41 are provided on both sides of the water tank 4 , a plurality of fans 42 are installed at one of the ventilation holes 41 , and an evaporation plate 9 is provided inside the water tank 4 near the bottom of the ventilation hole 41 .

[0036] It should be noted that the evaporation plate 9 is a honeycomb structure, and the spray water can pass through the surface of the evaporation plate 9 .

[0037] In this embodiment: through this design, the spray water falls on the surface of the evaporation plate 9 after heat exchange, and the fan 42 blows air to the ventilation hole 41, so that the spray water evaporates on the surface of the evaporation plate 9, reducing the temperature of the spray water, which is convenient for the recycling of the spray water. The evaporation occurs on the surface of the evaporation plate 9, so that the scale is mostly formed on the evaporation plate 9, which is convenient for centralized cleaning of the scale.

[0038] Going further:

[0039] In an optional embodiment, a slot matching the condensation plate 2 is provided on the inner side of the housing 1 .

[0040] In this embodiment: through this design, the connection between the condensing plate 2 and the box body 1 is stable, and the exposed end of the coil 21 is prevented from colliding with the surface of the cover plate 3 when the cover plate 3 is installed.

[0041] Working principle and use process of the utility model: When using the utility model, the user can select a suitable number of condensing plates 2 according to the refrigerant condition of the refrigeration equipment, connect the condensing plates 2 in series through the connecting pipe 7, change the stroke of the refrigerant heat exchange operation, connect the refrigerant pipeline to the exposed end of the coil 21, and then start the circulating water pump 5. When the refrigerant enters the box body 1, the circulating water pump 5 transports the spray water to the spray head 8 through the hose 6. The spray head 8 sprays on both sides of the condensing plate 2, and the spray water forms water on the surface of the condensing plate 2. The membrane exchanges heat with the refrigerant in the coil 21, and the spray water is in a flowing state, which can avoid the formation of scale on the surface of the condensation plate 2. The spray water falls after heat exchange, and part of it stays on the surface of the evaporation plate 9. The fan 42 blows air to the ventilation hole 41, so that the spray water evaporates on the surface of the evaporation plate 9, thereby reducing the temperature of the spray water and facilitating the recycling of the spray water. The evaporation occurs on the surface of the evaporation plate 9, so that the scale is mostly formed on the evaporation plate 9, which is convenient for centralized cleaning of the scale; part of the spray water passes through the evaporation plate 9 and falls into the water tank 4, which can be recycled.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
