[0007] By adopting the above technical solution, air can flow between the upper cavity and the lower cavity through the upper cavity, the lower cavity and the second heat dissipation hole, and then pass through the second heat-conducting layer and the first heat-conducting layer. When the top of the upper PVC board is heated, it can have a good heat-conducting effect, and then the heat can be quickly dissipated through the circulating air. This board has good high-temperature resistance and can effectively reduce the problem of reduced reliability when encountering a high temperature of 60-80 degrees.

[0011] Specifically, first heat dissipation holes are formed through one side of the upper PVC plate and the lower PVC plate.

[0012] Specifically, the upper cavity and the lower cavity are both composed of multiple groups of grooves distributed transversely and longitudinally.

[0013] By adopting the above technical solution, the upper cavity and the lower cavity composed of multiple groups of transversely and longitudinally distributed grooves can enable the air to effectively contact the inner side of the upper PVC sheet and the lower PVC sheet, which is beneficial to take away the heat from the upper PVC sheet and the lower PVC sheet.

[0014] Beneficial effects of the utility model:

[0025] When in use, air can flow between the upper cavity 5 and the lower cavity 6 through the upper cavity 5, the lower cavity 6 and the second heat dissipation hole 9, and then pass through the second heat-conducting layer 7 and the first heat-conducting layer 3. When the top of the upper PVC board 1 is heated, it can have a good heat-conducting effect, and then the heat can be quickly dissipated through the circulating air. This board has good high-temperature resistance and can effectively reduce the problem of reduced reliability when encountering a high temperature of 60-80 degrees.

[0026] For example, Figure 1-3 As shown, the utility model also includes that the heat-resistant layer 4 is made of glass fiber material.

[0031] When in use, the first heat dissipation holes 8 can further improve the heat dissipation effect of the upper PVC board 1 and the lower PVC board 2 .

[0032] For example, Figure 3-4 As shown, the utility model also includes that the upper cavity 5 and the lower cavity 6 are both composed of multiple groups of grooves distributed transversely and longitudinally.

The top of the upper PVC sheet 1 is the heated end. The heat-resistant layer 4 made of glass fiber material has good heat resistance, which can effectively improve the heat resistance of the PVC sheet close to the high-temperature side. The air can flow between the upper cavity 5 and the lower cavity 6 through the upper cavity 5, the lower cavity 6 and the second heat dissipation hole 9, and then through the second heat-conducting layer 7 and the first heat-conducting layer 3, when the top of the upper PVC sheet 1 is heated, it can have a good heat-conducting effect. The upper cavity 5 and the lower cavity 6 composed of multiple groups of transversely and longitudinally distributed grooves can make the air effectively contact with the inner sides of the upper PVC sheet 1 and the lower PVC sheet 2, which is beneficial to take away the heat on the upper PVC sheet 1 and the lower PVC sheet 2.
