[0026] According to design requirements, four connecting plates can be fixed on the first collecting pipe 13 to divide it into three first liquid conducting chambers 131, and four connecting plates can be fixed on the second collecting pipe 14 to divide it into three second liquid conducting chambers 141. Correspondingly, four flattened solid strips 112 can be set on the flat tube 11 to form five circulation channels 113. All designs can be expanded in this way in turn.

[0027] Furthermore, the first liquid guide cavity 131 at the right end of the first collecting tube 13 of the condenser 10 is connected to the first connector 1, and the first connector 1 is welded and fixed to the outer wall of the first collecting tube 13 of the condenser 10; the second liquid guide cavity 141 at the left end of the second collecting tube 14 of the condenser 10 is connected to the second connector 2, and the second connector 2 is welded and fixed to the outer wall of the second collecting tube 14 of the condenser 10; the first liquid guide cavity 131 at the right end of the first collecting tube 13 of the evaporator 20 is connected to the third connector 3, and the third connector 3 is welded and fixed to the outer wall of the first collecting tube 13 of the evaporator 20; the second liquid guide cavity 141 at the left end of the second collecting tube 14 of the evaporator 20 is connected to the fourth connector 4, and the fourth connector 4 is welded and fixed to the outer wall of the second collecting tube 14 of the evaporator 20.

[0028] Furthermore, the first connector 1 is connected to a main feed pipe 40, the second connector 2 is connected to one end of the shut-off device via a connecting pipe, the other end of the shut-off device is connected to the third connector 3 via a connecting pipe, and the fourth connector 4 is connected to a discharge pipe 70.

[0029] The intercepting device is composed of a dryer 50 and a capillary 60. The second connector 2 is connected to one end of the dryer 50 through a connecting tube, the other end of the dryer 50 is connected to one end of the capillary 60, and the other end of the capillary 60 is connected to the third connector 3 through a connecting tube.

[0030] The dryer 50 and the capillary tube 60 are both commonly used components in refrigeration equipment, and both can adopt existing known structures, which will not be described in detail here.

[0031] Furthermore, the condenser 10 and the evaporator 20 are arranged side by side.

[0032] Furthermore, the outer wall surface of the main feed pipe 40 is covered with an elastic protective sleeve 41 .

[0033] Furthermore, the discharge pipe 70 is covered with a second elastic protective sleeve 71. The outer wall surface of the capillary tube 60 may also be covered with an elastic protective layer.

[0034] like Figures 1 to 4As shown, when the present embodiment is in use, the refrigerant (coolant) enters the first liquid guide cavity 131 at the right end of the first header 13 of the condenser 10 from the main feed pipe 40, then passes through the circulation channel 113 at the right side of the corresponding flat tube 11, and then enters the second liquid guide cavity 141 at the right end of the second header 14 of the condenser 10, and then enters the circulation channel 113 in the middle of the corresponding flat tube 11, and then enters the first liquid guide cavity 131 at the left end of the first header 13 of the condenser 10, and then enters the circulation channel 113 at the left side of the corresponding flat tube 11. 113, then enters the second liquid guide cavity 141 at the left end of the second liquid guide cavity 141 of the condenser 10, then enters the dryer 50 to be dried, then enters the capillary 60, and then enters the first liquid guide cavity 131 at the right end of the first collecting tube 13 of the evaporator 20, and then, as the flow of the condenser 10, finally flows out from the second liquid guide cavity 141 at the left end of the second collecting tube 14 of the evaporator 20, and flows out from the discharge pipe 70 to the subsequent components (in this embodiment, it flows to the compressor, which is a conventional structure and will not be described in detail here).

[0035] In this embodiment, the condenser 10 and the evaporator 20 only need a single flat tube 11, a first header 13, a second header 14 and a plurality of heat exchange fins 12. The assembly and welding are convenient, which greatly improves the processing efficiency and has a good use effect.

[0036] The shutoff device may also directly adopt a throttle valve, which may connect the second connector 2 with one end of the throttle valve through a connecting pipe, and the other end of the throttle valve with the third connector 3 through a connecting pipe.

[0037] This structure directly replaces the dryer 50 and the capillary tube 60 with a throttle valve, and its effect is basically the same as that of using the dryer 50 and the capillary tube 60, but its structure is simpler and easier to manufacture. The throttle valve can adopt various throttle valves used in existing known refrigeration systems, which will not be described in detail here and is not shown in the drawings.

[0038] Finally, the above implementation modes are only used to illustrate the present invention, but not to limit the present invention.
