[0022] Figure 5 yes Figure 4 A schematic diagram of the local structure from a different angle. Detailed implementation method:

[0023] For example, see below. Figures 1 to 5 As shown, a heat exchanger with a water inlet structure includes a V-shaped body 10. The body 10 includes four heat exchange modules 20. Every two heat exchange modules 20 are aligned vertically to form a group of main heat exchange modules. The two main heat exchange modules are located on the left and right sides, with their rear sides close to each other and their front sides far apart, forming a V shape.

[0024] The top connecting plates of the two upper heat exchange modules 20 are fixed to the same top end plate, which improves the connection between the two upper heat exchange modules 20.

[0025] The heat exchange module 20 includes multiple S-shaped coiled heat exchange tubes 21, and all heat exchange tubes 21 are simultaneously fixed on multiple heat dissipation fins 22.

[0026] All heat exchange modules 20 are fixed at their rear ends on a vertically extending rear-bent connecting plate 40, and the inlet and outlet ends of the heat exchange tubes 21 of all heat exchange modules 20 extend out of the rear wall of the rear-bent connecting plate 40.

[0027] In this embodiment, four heat exchange modules 20 are used to form the heat exchange body, which greatly increases the heat exchange area. At the same time, each heat exchange main module consists of two heat exchange modules 20 aligned vertically. Compared with a single vertical heat exchange main module, this reduces the difficulty of processing and facilitates subsequent partial replacement and maintenance.

[0028] Furthermore, a central support rod 1 is fixed between the front parts of the two lower heat exchange modules 20. This structure improves the connection strength between the two lower heat exchange modules 20.

[0029] Furthermore, a water receiving tank 30 is provided between two adjacent heat exchange modules 20. The top plate of the water receiving tank 30 is fixed to the bottom connecting plate of the two upper heat exchange modules 20, and the bottom plate of the water receiving tank 30 is fixed to the top connecting plate of the two lower heat exchange modules 20. A drain connector 31 is connected to the bottom plate of the part of the water receiving tank 30 between the two main heat exchange modules. An upper through groove 32 is formed on the top plate of the part of the water receiving tank 30 between the two main heat exchange modules, and the upper through groove 32 communicates with the water receiving tank 30.

[0030] The middle part of the front wall plate of the water collecting groove body 30 extends rearward to form a front vertical groove 33.

[0031] The top end of the front wall plate of the water collecting groove body 30 near the corresponding heat exchange module 20 is formed or welded with a forward and upward inclined guide plate part 34, and the outer side of the guide plate part 34 is near the inner side wall of the corresponding heat exchange module 20.

[0032] In use, the external wind of the water collecting groove body 30 of the present embodiment blows into the heat exchange module 20 from the rear to exchange heat, and the heat-exchanged wind blows out from the front of the heat exchange module 20. During the heat exchange process, the water droplets of the heat exchange module 20 above fall downward along the heat exchange pipe 21 and the heat dissipation fin 22. In this process, the falling water droplets are blown forward by the wind blowing through the heat exchange module 20 from the rear to the front, and then fall into the upper through groove 32 of the water collecting groove body 30 below, and then accumulate in the water collecting groove body 30. The water collecting groove body 30 is provided with a drain connection pipe (not shown in the drawing) at the drain connection head 31, and the water in the water collecting groove body 30 is drained from the drain connection pipe, so that the water droplets of the heat exchange module 20 above basically do not fall into the heat exchange module 20 below, thereby ensuring the normal heat exchange of the heat exchange module 20 below, and the water droplets do not block the flow of wind to affect the heat exchange, which ensures the overall heat exchange effect and heat exchange efficiency of the present embodiment.

[0033] The above embodiments are only used to illustrate the present application, and are not limited to the present application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, all equivalent technical solutions also belong to the scope of the present application, and the patent protection scope of the present application should be defined by the claims.
