Abstract
An automatic heat dissipating device comprises a power supply module, a temperature sensing module, a switch control module and a heat dissipating module, wherein the output end of the power supply module is connected with the temperature sensing module and the power supply input end of the switch control module, the signal output end of the temperature sensing module is connected with the control signal input end of the switch control module, and the switch control end of the switch control module is connected with the power supply end of the heat dissipating module. When temperature changes, the temperature sensing module correspondingly moves till the switch control module is driven to move to control the heat dissipating module to begin working. The temperature sensing module can adopt a thermo-sensitive resistor as a temperature-sensing element, and therefore, the automatic heat dissipating device can control the heat dissipating module to work and dissipate heat in real time according to the current environmental temperature, which is suitable for applying in the occasions such as a box type transformer station and the like which have limitation to environmental temperature, and does not need manual intervention.

Embodiment
Embodiment:
A kind of automatic heat radiator, as shown in Figure 1, this device comprises transformer T, rectifier bridge VD1～VD4 (IN4007*4), pressurizer IC1 (78L05), thermistor RT, switching tube IC2 (8752), relay K, fan M, wherein, the elementary winding of transformer T is attempted by on the 220V mains supply, the secondary winding of transformer T connects the input 1 of rectifier bridge VD1 ~ VD4,3 pin, output 4 pin of rectifier bridge VD1 ~ VD4 connect input 1 pin of pressurizer IC1, output 3 pin of pressurizer IC1 are leaded up to 1 pin of thermistor RT serial connection switching tube IC2,1 pin of switching tube IC2 is also by an adjustable resistance RP ground connection, the 2 pin ground connection of switching tube IC2, its 3 pin power end connect output 3 pin of pressurizer IC1 by resistance R 1; Be connected the coil of relay K between output 4 pin of switching tube IC2 and output 3 pin of pressurizer IC1, the series circuit of the normal opened contact of relay K and fan M is attempted by on the 220V mains supply.
Signal after transformer T transformation is handled enters pressurizer IC1 voltage stabilizing afterwards and handles again through rectifier bridge VD1 ~ VD4 rectification; When if ambient temperature is low, thermistor RT is in high-impedance state, when ambient temperature raises, the corresponding reduction of the resistance of thermistor RT, the pressure drop of thermistor RT current output terminal raises, when the voltage of thermistor RT current output terminal is elevated to the action threshold value of switching tube IC2, switching tube IC2 action, (switching tube IC2 is connected to and exports high level at ordinary times the output low level signal, output low level signal during action), there is pressure drop on the relay K coil, begins action, its normal opened contact adhesive, fan has just been started working; When ambient temperature descended, the corresponding rising of the resistance of thermistor RT stopped action up to switching tube IC2.
As above as seen, whether automatic heat radiator of the present utility model can dispel the heat according to the automatic control of ambient temperature, does not need manual intervention.
