Fig. 2 is the circuit diagram of the utility model server host heat abstractor.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1 and Figure 2, server host heat abstractor, comprise temperature sensing unit, operation amplifier unit, switch element, go out fan, air intake fan and indicating member.
Described temperature sensing unit comprises thermistor Rt0, slide rheostat Rp, resistance R1 and resistance R2, thermistor Rt0 mono-termination DC power supply, ground connection after other end resistance in series R1; The movable end of slide rheostat Rp and a stiff end termination DC power supply, ground connection after another stiff end resistance in series R2; The node a of thermistor Rt0 and resistance R1 connects the positive input of operation amplifier unit, and the node b of slide rheostat Rp and resistance R2 connects the reverse input end of operation amplifier unit.
