Temperature control apparatus with heat exchanging unit divided into evaporator and condenser sections

A temperature control apparatus disposed in a first environment and a second environment, comprising:

• a heat exchanging unit independently divided into a first heat exchanging portion disposed at the first environment and a second heat exchanging portion disposed at the second environment, wherein the heat exchanging unit comprises a plurality of heat-dissipating fins and a pipe running in the first heat exchanging portion and then running in the second heat exchanging portion, the pipe comprises an inlet and an outlet disposed in the first heat exchanging portion and the second heat exchanging portion respectively, the inlet and the outlet are connected with a circulation loop, the heat-dissipating fins are continuously disposed in the first heat exchanging portion and the second heat exchanging portion and configured to cool the pipe;
• and
• a working fluid flowing in the pipe;
• wherein the pipe has a larger pipe diameter around the inlet and the outlet, and has a smaller pipe diameter away from the inlet and the outlet;
• the smaller pipe diameter of the pipe has the capillary function for regulating the pressure of the working fluid in the first and second heat exchanging portions so as to enhance the heat exchange efficiency of the heat exchanging unit.
