Description
Technical field
The utility model relates to the electric defroster that a kind of automatic constant-temperature controls.
Background technology
Need to defrost during passenger vehicle runs in the winter time, generally use the electric defroster of safer employing PTC calandria, but existing electric defroster only has Push And Release two grades, temperature adjustment cannot be carried out, need PTC calandria to be connected with heat radiator to carry out thermostatic control, and the use of heat radiator can expend larger electricity, this is a larger loss for using pure electrodynamic city bus, therefore needs to improve the control circuit of PTC calandria.
Utility model content
Technical problem to be solved in the utility model is to provide the electric defroster that the few automatic constant-temperature of a kind of power consumption controls.
The utility model solves the problems of the technologies described above adopted technical scheme: the electric defroster that a kind of automatic constant-temperature controls, and comprises PTC calandria, IGBT drive circuit, blower fan and high-voltage power supply; Also comprise power module, single-chip microcomputer, PWM drive circuit, for responding to the temperature sensor of PTC calandria temperature and the contactor for controlling high-voltage power supply and IGBT drive circuit break-make, single-chip microcomputer, PWM drive circuit and contactor are electrically connected with power module respectively, PWM drive circuit and temperature sensor are electrically connected with single-chip microcomputer respectively, and IGBT drive circuit, contactor and blower fan are electrically connected with PWM drive circuit respectively.
Compared with prior art, the utility model has the advantage of the feedback of single-chip microcomputer according to temperature sensor, the wind speed of blower fan is regulated by PWM drive circuit, and the adhesive of control contactor switches the break-make of IGBT drive circuit and high-voltage power supply simultaneously, regulate the thermal value of PTC calandria, make output temperature form closed-loop control, thus save heat radiator, reduce the consumption of electric energy.
As improvement, also comprise gear rotary switch, gear rotary switch is electrically connected with single-chip microcomputer.Use suitable output temperature, avoid the waste of electric energy.
