[0030] Embodiment 1

[0031] As shown in Figures 1-4 The present embodiment provides a clothes drying equipment, comprising an evaporator 1, a condenser 2, an air inlet duct 3, a compressor 4, an auxiliary heating device 5 and a condenser support 6, the evaporator 1, the condenser 2 and the auxiliary heating device 5 are placed in the air inlet duct 3, the condenser 2 and the auxiliary heating device 5 are fixed on the condenser support 6, the condenser 2 comprises a first heat exchange assembly 201 and a second heat exchange assembly 202, the first finned tube 203 of the first heat exchange assembly 201 and the second finned tube 204 of the second heat exchange assembly 202 are different in pipe diameter, and the auxiliary heating device 5 is arranged between the first heat exchange assembly 201 and the second heat exchange assembly 202.

[0032] The evaporator 1 cools and dehumidifies the incoming air, reduces the air humidity, and transfers the heat of the refrigerant to the air through the first heat exchange assembly 201 and the second heat exchange assembly 202 to heat the air for drying the clothes. The auxiliary heating device 5 is located between the two heat exchange assemblies, which solves the problem of low efficiency of the first heat exchange assembly of the condenser in a clothes drying device when the ambient temperature is relatively low (such as less than 15℃), further improves the air temperature, and ensures that the ideal drying temperature is reached. The compressor 4 provides power to drive the refrigerant to circulate between the evaporator 1 and the condenser 2, realizing the transfer of heat from the evaporator to the condenser. By changing the pipe diameter of the finned tube on the first heat exchange assembly 201 or the second heat exchange assembly 202, the design of the finned tube with different pipe diameters can optimize the fluid flow characteristics according to the actual heat exchange requirements, improve the heat exchange efficiency, reduce the energy consumption, make the device more suitable for the working requirements of the ambient temperature, improve the working efficiency of the condenser, reach the working state faster, shorten the drying time of the clothes, and achieve better user experience.

[0033] This setting, combined with the functions of the condenser 2 and the auxiliary heating device 5, can heat the air to the required temperature faster, shorten the drying time, improve user satisfaction, reduce the finned tube diameter, significantly reduce the demand cost of heat exchange materials, significantly reduce the overall refrigerant charge, further reduce production costs, protect the environment, and be more energy-saving and environmentally friendly.

Smaller S1 helps to quickly increase the air temperature, especially during the start-up phase or when dealing with high humidity clothes, which can heat the air to the required drying temperature faster. Larger S2 allows the second heat exchange assembly 202 to work at a relatively stable temperature, avoiding efficiency decline or component aging caused by premature contact with high-temperature air.
