DETAILED DESCRIPTION

[0023] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. Terms such as "horizontal", "vertical", and "overhanging" do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1-4 As shown, a split evaporator includes a heat exchange module and a header 1; the heat exchange module includes a front heat exchange module 2 and a rear heat exchange module 3; protective plates 4 are provided on the left and right sides of the heat exchange module; the header 1 is placed on the upper and lower sides of the front heat exchange module 2 and the rear heat exchange module 3;

[0027] The front heat exchange module 2 and the rear heat exchange module 3 are both provided with heat dissipation fins 5 on the front and rear sides, and a liquid inlet 6 and an air outlet 7 are provided on the left side of the collecting pipe 1 located at the top of the heat exchange module; a connecting pipe 8 is provided on the left side of the collecting pipe 1 located at the bottom of the heat exchange module, and the connecting pipes 8 of the front heat exchange module 2 and the rear heat exchange module 3 are rotated and fixed by a joint sleeve 9 after docking; a docking column 10 is provided on the right side of the collecting pipe 1, and the docking column 10 is rotated and fixed by a nut 11 after docking; a connecting plate 12 is provided on the left side protective plate 4 of the rear heat exchange module 3, and a clamping mechanism 13 is provided on the left side protective plate of the front heat exchange module 2, and the connecting plate 12 is docked and fixed with the clamping mechanism 13.

[0028] like Figure 1 , 3 As shown in , 4, the connecting pipe 8 and the docking column 11 are both arranged in a semicircular shape, and the arc surface of the connecting pipe 8 and the docking column 11 is provided with a continuous external thread; each set of relative connecting pipes 8 and docking column 11 planes can be docked on one side to form a cylinder, that is, to ensure that they can form a rotational fit with the connecting sleeve.

[0029] like Figure 1 As shown, the width of the manifold 1 is greater than the width of the front heat exchange module 2 and the rear heat exchange module 3, so that a gap is left between the two groups of heat exchange modules to improve the heat dissipation efficiency.

[0030] like Figure 1-2 As shown, the clamping mechanism 13 is composed of a U-shaped frame 1301 and a limiting column 1302; a limiting column 1302 is provided in the middle of the U-shaped frame 1301, a fixing plate 1303 is provided on the limiting column 1302 located inside the U-shaped frame 1301, a spring 1304 is provided between the fixing plate 1303 and the U-shaped frame 1301, and a pressing block 1305 is provided after the limiting column 1302 passes through the U-shaped frame 1301, and the limiting rod can be easily pulled to cooperate with the connecting plate through the pressing block.

[0031] like Figure 2 As shown, a blind hole is provided on the protective plate 4 to match one end of the limiting column 1302, so that the limiting column can be embedded in the blind hole when subjected to the elastic force of the spring, thereby preventing the limiting column from shaking greatly.

[0032] like Figure 2 As shown, a fixing hole is provided on the connecting plate 12, and the diameter of the fixing hole is larger than the diameter of the limiting column 1302. The limiting column can be inserted into the fixing hole to finally fix the fixing plate, which can effectively prevent displacement between the heat exchange modules. At the same time, since there are more connecting pipes in this area, a snap-on structure is more convenient for operation.

[0033] like Figure 3 As shown, a protrusion 801 is provided on the outer wall of the connecting pipe 8, and the joint sleeve 10 is rotatably connected to the connected connecting pipe through a thread. After the bottom of the joint sleeve 10 contacts the protrusion 801, the top of the joint sleeve 10 does not contact the top of the connecting pipe 8 and a gap is left. The gap area is used to connect the two groups of connecting pipes, that is, to complete the connection of the two groups of collecting pipes.

[0034] like Figure 3 As shown, a rubber pad is provided between the two groups of connecting pipes 8. When the connecting pipes are butt-jointed, the rubber pad is placed between the two. When the joint sleeve and the connecting pipes rotate, the two groups of connecting pipes can squeeze the rubber pad to further ensure the sealing between the connecting pipes and prevent water leakage.

[0035] The working principle of the utility model is explained as follows: when in use, two groups of heat exchange modules are docked, first the connecting plate is clamped into the clamping mechanism to complete the preliminary docking of the two groups of modules, then the docking column is rotated and fixed by bolts, and the connecting pipe is docked by the joint sleeve, thus completing the fixation of the four corners of the two groups of heat exchange modules, and then the two groups of heat exchange modules are connected to complete a combined heat exchange module.

[0036] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
