Temperature control apparatus and heat exchanging unit thereof

Abstract

A temperature control apparatus is disposed in a first environment and a second environment. The temperature control apparatus includes a heat exchanging unit, a compressor, a circulation loop, and a working fluid. The heat exchanging unit is divided into a first heat exchanging portion and a second heat exchanging portion. The heat exchanging unit includes a pipe and multiple heat-dissipating fins for cooling the pipe. The pipe is disposed in the heat exchanging unit. The pipe runs in the first heat exchanging portion and then runs in the second heat exchanging portion. The first heat exchanging portion is correspondingly disposed at the first environment. The second heat exchanging portion is correspondingly disposed at the second environment. The circulation loop is communicated to the heat exchanging unit and the compressor. The compressor compresses the working fluid to flow in the circulation loop.
