1. A heating and cooling device disposed in a pressure-volume-temperature equipment and used to heat and cool a testing plastic material, the heating and cooling device comprising:
a conductive structure comprising a main body and a test space formed in the main body for placing the testing plastic material;
an electric heating pipe attached on the main body for heating the testing plastic material in the test space through the main body; and
a housing disposed outside the conductive structure and separated from the main body to form a cooling flow channel, wherein the housing has an air inlet and an air outlet for cooling airflow to enter and exit the cooling flow channel to cool the testing plastic material.
