[0002] With the continuous development of automotive air conditioning boxes, the current demand for air conditioning boxes is also increasing, especially for energy-saving, safe and reliable air conditioning systems.

[0003] In the existing evaporator in the air conditioning box, the stamping process is adopted, which solves the problem that the D-shaped drawing tube structure formed by extrusion is unevenly deformed during the drawing process, resulting in relatively low overall structural strength of the evaporator; however, the assembly accuracy of the evaporator obtained by the stamping process still needs to be improved.

Further, the plurality of protrusion structures arranged at intervals included in the second limiting member 23 correspond to the part of the flanging 11 of the housing 10 where the toothed notch structure 12 is not provided.

[0054] In another embodiment, the first limiting member 21 and the second limiting member 23 are connected to form a fourth protrusion structure 24; the fourth protrusion structure 24 and the flat tube 60 do not contact each other.

[0056] At the same time, referring to Figure 5 , Figure 5 is a schematic diagram of another fourth convex structure 24 provided by this application. The direction of the first limiting member 21 can be vertical, horizontal, or inclined, and no specific limitation is made here either. At the same time, one end of the flat tube groove 22 close to the connection between the main board 20 and the housing 10 is extended to form the second limiting member 23; referring to Figure 4 and Figure 5 , the second limiting member 23 extends to the edge position of the side of the main board 20 that protrudes upward, and the length of the second limiting member 23 is less than the length of the above-mentioned fourth convex structure 24.

[0058] In one embodiment, a buckle 25 is provided on the side of the main board 20; the buckle 25 fits along the flanging 11 with the housing 10.

[0059] Among them, referring to Figure 3 , when the main board 20 and the housing 10 are assembled, the buckle 25 provided on the side of the main board 20 is attached to the outer surface of the housing 10 along the flanging 11 direction of the housing 10, which is beneficial to strengthening the assembly uniformity of the main board 20 and the housing 10, further improving the qualified rate of soldering, and reducing the leakage risk.

[0060] In one of the embodiments, grooves are respectively provided on the housing 10 and the main board 20, and the assembly connection with the spacer 40 is realized through the grooves. The depth of the grooves is set to be relatively small, generally 0.15 mm.

[0061] Furthermore, in the present application, the housing 10, the main board 20, the end cover 50, the spacer 40, and the partition board 30 of the evaporator 100 are formed by stamping a sheet material with a wall thickness of 0.8 mm - 1 mm; while the existing D-shaped drawn tube generally uses a material with a wall thickness of 1.2 mm. It can be seen that the evaporator 100 provided in the present application is lighter in weight, and has a higher production efficiency compared with the integrally stamped D-shaped drawn tube structure, which is beneficial to improving the competitiveness of the product.

[0062] For the evaporator 100 provided in the present application, by setting the structure of the M-shaped housing 10 and the spacer 40, the arc area of the housing 10 is enhanced, and the overall structural strength is further increased. At the same time, the accommodation cavity of the evaporator 100 is divided into multiple chambers by the spacer 40 and the partition board 30, so that the evaporation medium circulates between the multiple chambers and the flat tube 60, thereby improving the working efficiency of the evaporator 100.

[0063] The evaporator 100 is a heat exchanger, which is responsible for converting the liquid refrigerant into a gaseous state through the evaporation process, thereby absorbing the indoor heat to achieve the function of air-conditioning cooling. When the compressor operates, the liquid refrigerant is compressed into a high-temperature and high-pressure gas and is transported into the evaporator 100 through a pipeline. After entering the evaporator 100, the high-temperature and high-pressure gas exchanges heat with the relatively low room-temperature air in the evaporator 100. During this process, the refrigerant releases heat, causing the gas temperature to drop. Due to the large surface area of the pipeline inside the evaporator 100, the air contacts the refrigerant more, and the heat exchange is faster. At the same time, the moisture in the air will condense into water after contacting the refrigerant and is discharged through the evaporator 100, which helps to dehumidify. After passing through the evaporator 100, the refrigerant changes from a liquid state to a gaseous state, and the indoor air becomes cool. The cooled air is sent back into the room to achieve the effect of air-conditioning cooling. By setting the evaporator 100 with relatively high structural strength provided in the present application in the air-conditioning system, it is beneficial to further realize the stability and safety of the air-conditioning system.

[0064] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0065] The above-described embodiments merely represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
