Abstract
A heating and cooling device includes a conductive structure, an electric heating pipe and a housing. The housing has a main body and a test space formed in the main body, the electric heating pipe is attached on the main body and used for heating a testing plastic material in the test space, and the housing is covered outside the conductive structure and separated from the main body to form a cooling flow channel. The housing and the main body are separated without contacting each other, so that the dissipation of the heat energy of the electric heating pipe through the housing can be reduced in the heating process, and the function of thermal preservation can be provided. Moreover, the cooling effect can be improved through the larger cooling flow channel during the cooling process. A PVT equipment using the heating and cooling device is further provided.
