Abstract

A cooling device and a cooling garment using the cooling device. The cooling device comprises a housing, a TEC cooling module, and a fan. The housing is provided with a connected air intake chamber and an air outlet chamber, with the fan arranged in the air intake chamber. The TEC cooling module is installed in the air outlet chamber, forming a cold air channel and a hot air channel within the air intake chamber. The two sides of the lower end surface of the housing are respectively provided with a natural air intake port and a heat exhaust port. The natural air intake port communicates with the air intake chamber and corresponds to the fan, while the heat exhaust port communicates with the hot air channel. One side of the upper end surface of the housing is provided with a cold air outlet that communicates with the cold air channel, and the other side of the upper end surface of the housing is provided with a cold air inlet that communicates with the air intake chamber. The cold air inlet corresponds to the fan, making the air intake chamber a mixed chamber for hot and cold air.
