[0028] The utility model proposes a kind of coil assembly 100 applied to air cooler 200.

[0029] Please refer to Figure 1 And Figure 2 In an embodiment of the utility model, the coil assembly 100 applied to air cooler 200 includes pipe body 1, liquid inlet section 11 and liquid outlet section 12;The pipe body 1 is helically arranged along the first direction extension;Liquid inlet section 11 and liquid outlet section 12 are communicated at the two ends of pipe body 1 respectively, liquid inlet section 11 has first port 111, liquid outlet section 12 has second port 121, first port 111 is equipped with first sealing element, second port 121 is equipped with second sealing element.

[0030] The technical solution of the present invention is to replace the existing ring-shaped or arc-shaped coil by setting the shape of the tube body 1 to a straight spiral shape, thereby simplifying the processing technology of the coil, avoiding the problem of large pitch at the bend of the coil, and increasing the outer diameter of the coil, thereby improving the efficiency of the coil in transporting refrigerant.

[0031] In this embodiment, the tube body 1 can be spirally extended along a first direction, thereby making the tube body 1 a coil extending spirally in a straight direction, thereby avoiding the problem of complex processing technology of existing ring-shaped or arc-shaped coils, and thus avoiding the problem of increased coil space occupied by the larger pitch at the bend of the coil. In addition, the outer diameter of the straight spiral coil is larger than the outer diameter of the existing ring-shaped or arc-shaped coils, thereby making the coil more efficient in transporting refrigerant. By setting the tube body 1 in a spiral shape, the heat exchange area between the tube body 1 and the cooling water is increased, so that the tube body 1 has a better heat exchange effect. In order to improve the airtightness of the pipeline connection between the coil and the compressor 3, the liquid inlet section 11 of the tube body 1 is provided with a first port 111 for assembling a first seal (not shown). The first seal is used to seal the connection between the first port 111 and the pipeline connected to the compressor 3. The first seal can be a rubber plug and a coating sealant. In order to improve the air tightness of the pipeline connection between the coil and the evaporator 31, the liquid outlet section 12 of the tube body 1 is provided with a second port 121 for assembling a second seal (not shown in the figure). The second seal is used to seal the connection between the second port 121 and the pipeline connecting to the evaporator 31. The second seal can be a rubber plug and a coating sealant, etc.

[0032] In this embodiment, the outer diameter of the tube body 1 is no less than 5 mm and no more than 10 mm. This makes the outer diameter of the linear spiral tube body 1 larger than the outer diameter of existing annular or arc-shaped coils, thereby improving the structural strength of the tube body 1 and the efficiency of the tube body 1 in transporting refrigerant. The outer diameter of the tube body 1 can be a common outer diameter of 5 mm, 6 mm, 7 mm, 8 mm, or 9.52 mm, thereby increasing the applicability of the tube body 1.

[0033] In this embodiment, the pitch of the tube body 1 is not less than 6 mm and not more than 20 mm, which avoids the problem that the pitch of the existing ring-shaped or arc-shaped coil is different in the straight part and the turning part, which is inconvenient to process. The tube body 1 can select an appropriate pitch for processing according to its own outer diameter, thereby making the straight spiral tube body 1 more convenient to process, thereby improving the production efficiency of the tube body 1.

[0034] In this embodiment, a tin plating layer is formed on the surface of the tube body 1. The surface treatment process of the tube body 1 can be electrolytic tin plating. The tin plating layer can be used to prevent the cooling water or refrigerant from corroding the tube body 1 over a long period of time, thereby preventing the tube body 1 from developing patina or rust during long-term use.

[0035] like Figure 2 As shown, in this embodiment, the liquid inlet section 11 is arranged tangentially to one side of the tube body 1, which makes it easier for the compressor 3 to connect to the liquid inlet section 11 through a pipeline. The liquid outlet section 12 is arranged tangentially to one side of the tube body 1, which makes it easier for the evaporator to connect to the liquid outlet section 12 through a pipeline, thereby allowing the tube body 1 to be suspended and immersed in cooling water, thereby increasing the heat exchange area between the tube body 1 and the cooling water.

[0036] In this embodiment, the tube body 1 spirally extends along the first direction and encloses a water passage cavity. The water passage cavity is circular, thereby increasing the heat exchange area between the tube body 1 and the cooling water. The outer diameter of the water passage cavity is not less than 50.5 mm and not more than 51.5 mm.

[0037] like Figure 1 and Figure 2 As shown, the liquid inlet section 11 is provided with a first connection portion 13 for communicating with the compressor 3, and the first connection portion 13 has a first port 111. The liquid outlet section 12 is provided with a second connection portion 14 for communicating with the evaporator 31, and the second connection portion 14 has a second port 121. The outer diameter of the first connection portion 13 is larger than the outer diameter of the tube body 1, and / or the outer diameter of the second connection portion 14 is larger than the outer diameter of the tube body 1.

[0038] In this embodiment, by providing the first connecting portion 13 and the second connecting portion 14 at the liquid inlet section 11 and the liquid outlet section 12, respectively, it is more convenient for the compressor 3 and the evaporator 31 to be connected to the liquid inlet section 11 and the liquid outlet section 12, respectively, through the pipeline. By providing the outer diameter of the first connecting portion 13 and / or the second connecting portion 14 to be larger than the outer diameter of the tube body 1, it is further facilitated to assemble the compressor 3 and the evaporator 31 with the first connecting portion 13 and / or the second connecting portion 14, respectively, through the pipeline.

[0039] The present invention also proposes an air cooler 200, which includes a coil assembly 100 applied to the air cooler 200. The specific structure of the coil assembly 100 applied to the air cooler 200 refers to the above embodiment. Since the air cooler 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0041] In this embodiment, a linear cooling groove 21 is provided in the water receiving tray 2 so that the outer shape of the cooling groove 21 matches the tube body 1 extending in a linear direction, thereby avoiding the need to process the turning point of the cooling groove 21 of the water receiving tray 2 (to match the turning point of the annular coil), thereby simplifying the processing technology of the water receiving tray 2.

[0042] In this embodiment, the air cooler 200 also includes a plurality of wet curtain assemblies (not shown), the water receiving tray 2 has a plurality of guide grooves connected to the cooling trough 21, and the plurality of wet curtain assemblies are arranged one-to-one in the plurality of guide grooves. The plurality of guide grooves are used to guide the water on the plurality of wet curtain assemblies into the cooling trough 21, thereby reducing the cooling cost of the coil.

[0043] In this embodiment, the air cooler 200 also includes a water supply component (not shown), which includes a water tank and a water pump connected to the cooling trough 21. The water pump is connected to multiple wet curtain assemblies through pipes, thereby facilitating the water pump to pump water in the water tank into multiple wet curtain assemblies.

[0044] like Figure 4 As shown, the air cooler 200 further includes a compressor 3 , an evaporator 31 and a connecting pipe 32 . The compressor 3 is connected to one end of the tube body 1 through the connecting pipe 32 , and the other end of the tube body 1 is connected to the evaporator 31 .

[0045] In this embodiment, the tube body 1 can be set to multiple and arranged at intervals in the cooling tank 21. The connecting pipe 32 can have connection ports corresponding to the number of coils. One end of the connecting pipe 32 is connected to the liquid inlet sections 11 of multiple tube bodies 1 through multiple connection ports, and the other end of the connecting pipe 32 is connected to the compressor 3.
