[0018] Embodiment, see as Figs. 1 to 4As shown, a heat exchange module for a clothes dryer includes a condenser 10, an evaporator 20, a capillary tube 30, and a compressor assembly 40. The condenser 10 is located behind the evaporator 20, and the compressor assembly 40 is located to the right of the condenser 10 and the evaporator 20.

[0019] Connecting plates 1 are fixed on the connecting housing 11 at both ends of the condenser 10, and the front ends of the two connecting plates 1 are fixed on the two fixing plates on the left and right sides of the evaporator 20.

[0020] The outlet end of the compressor assembly 40 is connected to the inlet end of the condenser 10 via a connecting pipe. The outlet end of the condenser 10 is connected to one end of the capillary connecting pipe 2. The other end of the capillary connecting pipe 2 is connected to one end of the capillary 30. The other end of the capillary 30 is connected to the inlet end of the evaporator 20. The outlet end of the evaporator 20 is connected to one end of the return pipe 3. The other end of the return pipe 3 is connected to the connector of one end of the external heat exchange connecting pipe 50. The connector of the other end of the external heat exchange connecting pipe 50 is connected to one end of the first bent connecting pipe 4. The other end of the first bent connecting pipe 4 is connected to the inlet end of the compressor assembly 40.

[0021] In this embodiment, four connectors are connected to the external heat exchange connecting pipe 50, with two connectors located at the left end of the external heat exchange connecting pipe 50 and two connectors located at the right end of the external heat exchange connecting pipe 50.

[0022] One connector at the left end of the external heat exchange connecting pipe 50 is connected to one end of the first bent connecting pipe 4, and one connector at the right end of the external heat exchange connecting pipe 50 is connected to one end of the return pipe 3.

[0023] The middle part of the capillary connecting tube 2 extends into the external heat exchange connecting tube 50. Both ends of the capillary connecting tube 2 extend out of the middle through holes of the corresponding connectors at the left and right ends of the external heat exchange connecting tube 50. The outer side wall of the capillary connecting tube 2 at the corresponding location is welded and fixed to the inner side wall of the corresponding connector.

[0024] Furthermore, the external heat exchange connecting pipe 50 is located below the condenser 10 and the evaporator 20. The top surface of the connecting plate 1 on the right side is formed with an upper groove 111, and the bottom surface of the connecting plate 1 on the right side is formed with a lower groove 12. The return pipe 3 is inserted into the lower groove 12.

[0025] The right-side bent section of the capillary connector 2 is inserted into the upper groove 111.

[0026] Furthermore, the left side of the capillary connecting tube 2 is formed with a bend 21 extending forward and backward, which is close to the right side wall of the left connecting plate 1.

[0027] Furthermore, the capillary tube 30 is located on the outside of the connecting plate 1 on the right side.

[0028] Furthermore, the outlet end of the capillary connecting tube 2 is connected to the large-diameter connection port of the reducing tube 6, and the inlet end of the capillary 30 is connected to the lower-diameter connection port of the reducing tube 6.

[0029] In this embodiment, the high-temperature, high-pressure gaseous refrigerant from the compressor assembly 40 enters the condenser 10. After heat dissipation, it forms a medium-temperature, high-pressure liquid, which then enters the capillary connecting pipe 2, and then the capillary tube 30, forming a low-temperature, low-pressure liquid. This liquid then enters the evaporator 20, where it absorbs and exchanges heat, becoming a low-pressure gas. It then flows through the return pipe 3 into the external heat exchange connecting pipe 50. The capillary connecting pipe 2 is located within the external heat exchange connecting pipe 50. Because the refrigerant in the capillary connecting pipe 2 is a medium-temperature, high-pressure liquid, while the refrigerant entering the external heat exchange connecting pipe 50 through the return pipe 3 is a low-temperature, low-pressure gas, the heat exchange between the two in the external heat exchange connecting pipe 50 lowers the temperature of the refrigerant entering the capillary tube 30, while raising the temperature of the refrigerant exiting the evaporator 20 and entering the external heat exchange connecting pipe 50. This increases the temperature of the refrigerant entering the compressor assembly 40, thereby improving the compression and temperature-raising efficiency of the compressor assembly 40.
