Be conducive to heat conduction.Heat in the course of the work, is constantly transferred to cold end, the accumulation of heat will by temperature-difference power generation module from hot junction
Cause the temperature of cold end to raise, so as to reduce the temperature difference between cold and hot two plate, influence generating efficiency.Apparatus of the present invention are due to cold end
The cold water of flowing, therefore the low temperature environment of cold end can be maintained.
The generating efficiency of temperature-difference power generation module is directly related with the temperature difference between heating surface and radiating surface, in order to fully excavate
Thermo-electric generation potentiality in the confined space, apparatus of the present invention heat exchanging face carries out the roughening processing of surface graphics, i.e., in institute
The temperature-difference power generation module surface stated hot water outlet metallic conduit outer surface and be affixed with it is patterned etching, carves depth
For 0.2 to 1 millimeter of the groove that graphically interlocks, figure can be that labyrinth shape, circular concentric, winding shape etc. can significantly increase heat exchange
The shape in face.These grooves are mutually matched so that temperature-difference power generation module heating surface is closely affixed with hot water metallic conduit, and is radiated
The area in face is also greatly increased.
Occasion for providing supply of electric power without power network, illumination depends on battery equal energy source.Due to apparatus of the present invention
There are electricity generation module and battery, therefore be adapted to itself provide illumination without extra outside independent illumination.In the hand of shell
A light switch is set on handle, it is serially connected between lighting module and battery.The lighting module includes taking from battery again
