[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown;

[0025] A spray cooling mechanism of an evaporative cooling device comprises a housing 1, a fan 2 is mounted on the top of the housing 1, and air inlet plates 3 are fixed on both sides of the housing 1;

[0026] In this embodiment: the existing CN218209883U {publication (announcement) number}: discloses an evaporative cooling device and an evaporative cooling air-cooled central air-conditioning. In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the existing evaporative cooling device sprays water directly on the top of the coil during spraying, and the spray water flows into the water tank under gravity. This spraying method makes a large amount of spray water only contact the upper surface of the coil, and the coil located below is difficult to fully contact with the spray water, affecting the heat exchange efficiency of the coil and the heat dissipation efficiency of the refrigerant in the coil". In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, the following improvement plan is proposed.

[0027] More specifically:

[0028] like Figures 1 to 5 As shown;

[0029] Combining the above:

[0030] A plurality of ventilation holes are provided on the surface of the air inlet plate 3 of the spray cooling mechanism of the evaporative cooling refrigeration equipment, a spray mechanism is installed in the shell 1, and the spray mechanism includes a water collecting tank 5 installed in the shell 1, the bottom of the water collecting tank 5 is connected to a spray water pump 6 through a pipeline, the output end of the spray water pump 6 is connected to a connecting pipe A7, the end of the connecting pipe A7 away from the spray water pump 6 extends to the top side of the shell 1, a three-way valve 8 is installed at one end of the connecting pipe A7 located in the top of the shell 1, connecting pipes B9 are installed at both ends of the three-way valve 8, a plurality of spray pipes 10 are symmetrically arranged on the outer side walls of the two connecting pipes B9, a solenoid valve 11 is installed at the connection between the spray pipe 10 and the connecting pipe B9, a plurality of spray heads 12 are evenly arranged on the outer side wall of the spray pipe 10, and a coil 20 is installed in the middle of the shell 1.

[0031] In this embodiment: When the utility model performs a spraying operation, the spray water pump 6 is started, and the water collecting tank 5 is provided with normal temperature spray water. The spray water pump 6 transports the spray water to the spray pipe 10 after passing through the connecting pipe A7, the three-way valve 8, and the connecting pipe B9. The opening and closing of the solenoid valve 11 is controlled by the external control module, so that the spray water can be sprayed to the coil 20 through the spray head 12. Since the spray head 12 is arranged horizontally, when the spray water is sprayed along the coil 20, it can spray the bottom side of the upper coil 20. Every two groups of spray heads 12 can spray the upper and lower surfaces of the coil 20 in place, thereby increasing the contact area between the spray water and the coil 20, thereby improving the heat exchange efficiency between the coil 20 and the spray water, which is helpful for cooling and liquefying the refrigerant.

[0032] It should be noted that the coil 20 is a single curved pipe coil, and its outlet is close to its inlet.

[0033] Going further:

[0034] In an optional embodiment, a water baffle 13 is installed inside the top side of the housing 1 .

[0035] In this embodiment: through this design, the water baffle plate 13 can prevent the spraying water from splashing out from the top of the shell 1 during the spraying operation, and the water baffle plate 13 can block the spraying water.

[0036] Going further:

[0037] In an optional embodiment, a water retaining curtain 4 is fixed inside the housing 1 at a position corresponding to the air inlet plate 3 .

[0038] In this embodiment: through this design, when the fan 2 is started, the outside air enters the shell 1 through the air inlet plate 3, and then is discharged from the fan 2, which is convenient for the evaporation of the spray water on the surface of the coil 20. The water retaining curtain 4 can prevent the spray water from spraying out from the air inlet on the surface of the air inlet plate 3, and the water retaining curtain 4 will not affect the entry of outside air.

[0039] Going further:

[0040] In an optional embodiment, a fixing seat 21 is fixed to the outer wall of one end of the coil 20 . The fixing seat 21 penetrates the shell 1 and extends to the outside of the shell 1 . Two connectors 22 are connected to the surface of the fixing seat 21 .

[0041] In this embodiment: through this design, the gaseous refrigerant enters the coil 20 from the connector 22, flows out from the other connector 22 through the coil 20 after being sprayed and cooled, and the liquid refrigerant can continue to participate in the refrigeration of the compressor.

[0042] Going further:

[0043] In an optional embodiment, the bottom of the water collecting tank 5 is a conical structure.

[0044] In this embodiment: through this design, it is convenient for the spray water pump 6 at the bottom to pump out the spray water in the water collecting tank 5. When the spray water in the water collecting tank 5 is reduced, it will not affect the operation of the spray water pump 6. The spray water in the water collecting tank 5 is regularly supplemented by the outside.

[0045] Going further:

[0046] In an optional embodiment, the sprinkler head 12 is disposed transversely at a gap corresponding to the coil 20 .

[0047] In this embodiment: through this design, every two spray heads 12 can spray the upper and lower surfaces of the coil 20 at the same time, thereby increasing the contact area between the spray water and the surface of the coil 20, thereby improving the heat exchange efficiency.

[0048] Working principle and use process of the utility model: When the utility model is in operation, the gaseous refrigerant of the compressor enters the coil 20 through the connecting head 22. When passing through the coil 20, the spray water pump 6 transports the spray water in the water collecting tank 5 to the spray pipe 10, and the spray water is sprayed out laterally from the spray head 12. Every two spray heads 12 can spray the upper and lower surfaces of the coil 20 at the same time, thereby increasing the contact area between the spray water and the surface of the coil 20, thereby improving the heat exchange efficiency and realizing spray cooling of the coil 20. The fan 2 inhales and discharges the outside air to promote the evaporation of the spray water and further improve the cooling efficiency. The spray water after spraying flows back to the water collecting tank 5 and can be recycled. The cooled liquid refrigerant returns to the compressor through the connecting head 22 to perform refrigeration operations.

[0049] 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. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
