The thermal conductivity of the aluminum plate 600 is higher than that of the glass panel 300, and the aluminum plate 600 can diffuse heat rapidly when being heated locally, so that the temperature between different regions on the glass panel 300 is homogenized, the temperature gradient is reduced, the thermal stress of the glass panel 300 is reduced, the probability of bursting of the glass panel 300 is reduced, and the safety of the glass panel 300 is improved.

While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
