power switch of the collector is a strong source of interference, the switch of the Thermal unit received should switch emitter, to ensure that the collector and heat distribution between the capacitance and because of the current inflow of the main circuit. To reduce heat and the distributed capacitance chassis, cooling unit should try to stay away from cases, if circumstances allow, there can be shielding the switch board.
