Please refer to FIG. 12-1 and FIG. 12-2, which are respectively a schematic structural diagram of the thermal bimetallic sheet in a normal temperature state and a structural schematic diagram in a heated state in one embodiment. As shown in FIG. 12-1 , in this embodiment, each thermal bimetal 213 is connected to three second heat sinks 222 correspondingly. For example, the middle of the thermal bimetal 213 is fixed on the heat dissipation plate 201 at the bottom of the air channel 102 .

The end of the thermal bimetal 213 is connected with the connecting rod. As shown in Fig. 12-2, for example, when the thermal bimetal 213 is deformed by heat, both ends of the thermal bimetal 213 are curved upwards. In this way, when the thermal bimetal 213 is heated and deformed, the three second heat sinks 222 located at the end of the thermal bimetal 213 are all lifted up by force. At this time, the second heat sink 222 leaves the through slot 250 and the heat conduction hole 350 , partially exposing the heat conduction plate 300 , thereby rapidly transferring the heat in the heat conduction plate 300 to the casing 100 under the flow of air, thereby improving the thermal conductivity of the heat conduction plate 300 cooling efficiency.
