Temperature-regulating fan

A temperature-regulating device, comprising:

• a fan;
• a housing in which a chamber is formed, wherein the housing is provided with an air inlet and an air outlet communicated with the chamber, and an air flow passage is formed between the air inlet and the air outlet;
• a wet curtain assembly comprising an evaporation unit provided in the air flow passage;
• and
• an air flow driving assembly configured to drive the air flow entering through the air inlet to the air outlet to be blown out through the air flow passage,
• wherein the temperature-regulating fan further comprises a vortex refrigeration assembly which includes a vortex refrigeration pipe, and the vortex refrigeration pipe at least controllably feeds the air flow blown by a cold end or a hot end into the air flow passage;
• and
• the temperature-regulating fan further comprising an exhaust passage provided in cooperation with the vortex refrigeration pipe, wherein the exhaust passage is provided to feed the air flow blown by one of the cold end or a hot end of the vortex refrigeration pipe into the housing when another of the cold end or a hot end of the vortex refrigeration pipe feeds the blown air flow into the air flow passage.
