However, although the conventional temperature equalizing plate has thermal conductivity, it has the following problems in actual use. Because the sealing length between the upper shell and the lower shell almost covers the upper shell and the lower shell The length of each side makes the welding and sealing process very cumbersome and difficult to process. In addition, the upper and lower shells are often due to high temperature during the welding and sealing process, and the internal capillary structure is changed. When heated again, it is easy to peel off or fall off from the upper shell and the lower shell. In addition, the temperature and pressure of the chamber inside the uniform temperature plate are constantly undergoing interactive changes in temperature and pressure during use, which is likely to cause the aforementioned problems such as leakage at the sealing weld.
