It is characterized in that the installation to increase the cooling efficiency.

At this time, the cold and warm element 5 is a thermoelectric semiconductor having a Peltier effect in which heat is generated or absorbed at a junction point when two types of semiconductors are bonded to each other and current flows. It works the opposite function.

Referring to the operation and effect of the present invention configured as described above are as follows.

First, the main configuration of the present invention system is a cylindrical inside that is installed in the rear portion in the state wrapped around the outside of the printed circuit board (2) inside the industrial heat probe camera that is installed for monitoring in a high temperature industrial site difficult for workers to access The housing 4 is installed, and the heat dissipation plate 6 and the heat dissipation fan 8 are sequentially installed in the rear opening of the inside housing 4 and the outside housing 3 covering the entire camera. In addition, in the inside of the heat dissipation heat sink 6 (that is, the inner side of the inside housing 4), the cold or hot element (5) that generates an endothermic or exothermic reaction in accordance with the supply direction of the power supply voltage is installed in close contact, 5) The cold air heat dissipation plate 7 and the cold air circulation fan 9 are sequentially installed in close contact with each other on the inner side surface.

At this time, the current flowing in the cold and warm element 5 is supplied with a predetermined voltage so that the endothermic reaction occurs on the cold air dissipation plate 7 side and the exothermic reaction on the heat dissipation heat sink 6 side, thereby generating cold air inside the camera. The heat generated by the rebound is generated outside the camera.

Therefore, the cold air generated inside the cold / heat element 5 is conducted to a large area through the cold air heat sink 7 having several heat dissipation fins, and the heat generated from the outside is a heat dissipation heat sink having a few heat dissipation fins ( Through 6) it is conducted over a large area.

At this time, the cold air heat sink (7) and the heat dissipation plate (6) inside and outside the cooling air circulation fan (9) and the heat discharge blow fan (8), respectively, the cold air heat sink including the cold and hot element (5) (7) and the cold air circulation fan 9 and the printed circuit board (2) are installed inside the cylindrical inner housing (4) having a predetermined space area, so that the cold and warm elements are conducted through the cold air heat sink (7) The cold air of (5) is dispersed into the grooves in the inner space of the inside housing (4) by the blowing action of the cooling air circulation fan (9) can prevent the printed circuit board (2) from rising above a certain temperature.

By preventing high temperatures, the camera itself can be made smaller and lighter, and the inside of the miniaturized camera can be cooled more effectively, anyone can easily install it, and it is very easy to maintain and manage. It is a very useful design because there is no fear of causing environmental pollution when discarded by using a cold and warm element with urea.
