Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is specifically described, drawings and Examples only for illustration of, be not used in restriction protection range.
As shown in Figure 1, the circuit diagram of Intelligent temperature control heater part of the present utility model, this intelligent device comprises heat-conducting unit 1, heat-generating units 2 and temperature detecting unit 3.Wherein heat-generating units 2 is Electrothermic wire, the heat pipe that heat-conducting unit 1 makes for Heat Conduction Material, as thermal conductive ceramic pipe etc.; Temperature detecting unit 3 is arranged between heat-generating units 2 and heat-conducting unit 1.
This device uses in circuit and comprises two circuit loops, is heating circuit and control loop.
Vout is the power supply output voltage of heat-generating units 2, after heat-generating units 2, connect temperature-control circuit, then forms with power supply the loop that generates heat.Set temperature control circuit in heating loop, and then power supply output voltage can be made to output to the controlled current flow of heat-generating units 2, and then it is controlled to realize power, temperature-controllable.This heat-generating units 2 is heating wire.
Ro is temperature detection build-out resistor, and temperature detecting unit 3 is subzero temperature thermistor NTC, Vsense is temperature detection sampled voltage, the i.e. voltage at temperature detecting unit 3 two ends, the change of sensing temperature is shown with the change list of this voltage, forms corresponding relation, carry out sensing temperature.And form thermometric loop with reference voltage V ref, when reality uses, the voltage source of measuring temperature basis voltage Vref and heating circuit voltage source can use same power supply.
Sampled voltage signal Vsense is delivered to temperature-control circuit, and temperature-control circuit can use singlechip chip, is connected in thermometric loop, and the control end of simultaneous temperature control circuit is connected in heating loop, in order to control the heating current in heating loop.
Although do not indicate temperature-control circuit and structure thereof in Fig. 1, according to current known technology, relatively simple many, such as use PIC series monolithic or ARM microcontroller chip, all can realize above-mentioned functions.After the control receiving sampled voltage, control end access heating loop can be controlled heating current, those skilled in the art all can directly realize, and concrete structure is not described in detail in this.
The operation principle of this device circuitry is: when exporting permission, then to produce power stage simultaneously heating up for heat-generating units 2, temperature detecting unit 3 draws the temperature T1 of heat-generating units 2 immediately by present sample voltage Vsense, and same reliably working can draw different phase temperature Tn by that analogy.If continue or increasing power output; then heat-generating units 2 temperature raises; now temperature detecting unit 3 draws the temperature Tx of heat-generating units 2 immediately by present sample voltage Vsense; if Tx protects a little higher than system temperature; then temperature detecting unit 3 is transported to temperature-control circuit singlechip chip by sampled voltage, and then regulates the electric current flowing through heat-generating units 2 to reduce power output, reduces temperature; thus reach the heating temp of safe and reliable control heat-generating units 2, make its reliably working at safe condition.
