In this scheme, the assembly process of the heat exchanger 100, the insulation tank 200 and the insulation cover 300 is simple to operate and the assembly efficiency is relatively high.

[0028] Among them, there are two water passage holes 310, the inlet section of the water passage 120 and the outlet section of the water passage 120 are both located on the side of the heat exchanger 100 facing the heat preservation cover 300, and the inlet section of the water passage 120 and the outlet section of the water passage 120 are correspondingly penetrated in the two water passage holes 310.

Furthermore, the heat exchanger 100 is a water-fluorine plate exchanger.

[0030] Alternatively, the two water passage holes 310 may be located at the first end of the insulation cover 300 (not shown in this scheme diagram); or the two water passage holes 310 may be located at the second end of the insulation cover 300 (not shown in this scheme diagram); or the two refrigerant passage holes 320 may be located at the first end of the insulation cover 300 (not shown in this scheme diagram); or the two refrigerant passage holes 320 may be located at the second end of the insulation cover 300 (not shown in this scheme diagram), etc.; all of the above may achieve the purpose of the present application, and the purpose does not deviate from the design concept of the present utility model, and will not be repeated here, and all should fall within the protection scope of the present application.

[0031] In one embodiment, if Figures 4 to 7 As shown, the notch of the heat preservation tank 200 faces the right side, the first end of the heat preservation cover 300 is the upper end of the heat preservation cover 300 , and the second end of the heat preservation cover 300 is the lower end of the heat preservation cover 300 .

[0032] In some examples, such as Figure 5 and Figure 7As shown, the heat-insulating cover 300 is a flexible member, and the hole wall of the water passage through hole 310 is provided with a first cut slit 311.

Since the heat-insulating cover 300 is flexible, the second cut slit 321 can be opened and closed, and the refrigerant passage 110 can be placed in the refrigerant passage through hole 320 from the second cut slit 321.

[0033] Among them, Figure 5 and Figure 7 As shown, in the up and down directions, the water passage hole 310 and the refrigerant passage hole 320 are located between the first cutting seam 311 and the second cutting seam 321, which is more conducive to quickly placing the water passage 120 in the water passage hole 310 and the refrigerant passage 110 in the refrigerant passage hole 320, and can effectively improve the assembly speed of the insulation cover 300.

[0034] In some examples, such as Figure 4 , Figure 5 and Figure 7 As shown, the third end of the insulation cover 300 is opposite to the fourth end of the insulation cover 300, the third end of the insulation cover 300 is provided with a first connecting edge 330, and the fourth end of the insulation cover 300 is provided with a second connecting edge 340, the first connecting edge 330 and the second connecting edge 340 are connected to the outer side surface of the insulation tank 200, so that the insulation cover 300 and the insulation tank 200 are connected together to prevent the insulation cover 300 from falling off during transportation.

[0035] Among them, Figure 7 As shown, the position where the first connecting edge 330 and the heat preservation cover 300 are connected includes the first connecting portion 331 and the first slit portion 332 which are alternately arranged, so that the first slit portion 332 can reduce the bending force when the first connecting edge 330 is bent relative to the heat preservation cover 300, and is more conducive to the bending of the first connecting edge 330 relative to the heat preservation cover 300. Furthermore, the position where the second connecting edge 340 and the heat preservation cover 300 are connected includes the second connecting portion 341 and the second slit portion 342 which are alternately arranged, so that the second slit portion 342 can reduce the bending force when the second connecting edge 340 is bent relative to the heat preservation cover 300, and is more conducive to the bending of the second connecting edge 340 relative to the heat preservation cover 300.

It can be that the temperature detection component is configured as a temperature sensing package, and the mounting hole is provided on the bottom wall of the heat preservation tank 200.

[0037] Among them, Figure 5 and Figure 6 As shown, the guide portion 220 is a guide rib, and the gap between the guide rib and the heat exchanger 100 is set to be no less than 0.5 mm, which is more conducive to the smooth installation of the heat exchanger 100 in the insulation tank 200.

The fixing part 500 is fixed on the heat preservation groove 200 and covers the temperature detection part installation hole and the wire groove 240 to prevent the temperature detection part and its connecting wire from falling. It can be that the temperature detection part and the heat exchanger 100 are filled with thermal conductive glue, and the heat of the heat exchanger 100 is transferred to the temperature detection part through the thermal conductive glue, so that the temperature detection part can detect the temperature of the heat exchanger 100.

[0039] Among them, Figure 4 and Figure 5 As shown, the material of the insulation tank 200 is set to foam, so that the insulation tank 200 has a certain strength and is not easy to deform; furthermore, the insulation cover 300, the first connecting edge 330 and the second connecting edge 340 are an integrated structure, and the material is set to sponge, so that the insulation cover 300 is relatively soft and easier to cooperate with the water passage 120 and the refrigerant passage 110 when the cover is installed in the notch of the insulation tank 200.

The fixing part 500 can be fixed to the insulation tank 200 by pasting, and the operation is simpler.

[0040] Among them, Figure 3 and Figure 6As shown, the bottom wall of the heat preservation tank 200 (i.e., the tank wall opposite to the same notch of the heat preservation tank 200) is provided with a through hole 260, and the heat exchanger 100 is provided with a stud 130, and the stud 130 extends out of the heat preservation assembly through the through hole 260. It can be that there is one through hole 260; or it can be that there are multiple through holes 260, and the multiple can be two, three or four, etc.; all of the above can achieve the purpose of this application, and its purpose does not deviate from the design concept of the utility model, and will not be repeated here, and all should fall within the protection scope of this application.
