But installation site shown in Fig. 1,4,5 is not limited to, and with being separated with insulating heat-conductive pad 4 in the middle of gate recess 1.Conveniently in insulation
Simultaneously on heat conduction to gate slot 1.
Further, above-mentioned U-shaped heater element 3 is the sheet metal with PTC effects that thermal insulation layer is wrapped up.Nickel chromium triangle
Alloy is high-resistance electrothermic alloy, and in length, the timing of cross-sectional area one, temperature is lower, and its resistance is smaller, constant in voltage
When, this characteristic is extremely advantageous to the quick heating of low temperature.
Further, two U-shaped open ends of U-shaped PTC heater elements 3 towards gate slot 1 outer end set (Fig. 1 is court
Upward), facilitate both positive and negative polarity to be drawn by two wires 6 from the two ends of the same area, then be respectively connected to the power supply of control system 7
Both positive and negative polarity output port.
There is voltage transformation module in above-mentioned control system 7, high voltage power supply can be converted to 36V safety power supplies and exported,
Have temperature sensor, for detecting temperature between gate and gate slot, can according to temperature change come the start and stop of automatic control circuit,
Also there is MANUAL CONTROL mode simultaneously.
Further, the joule thermal source gate recess of the present invention that identical quantity is installed according to gate recess particular number is prevented
Refrigeration system.As shown in figure 1, fan brake door 2 is at least equipped with two symmetrical gate recess 1, it can be filled along the every side of gate slot 1
Multiple U-shaped continued accesses of PTC heater elements 3, but in order to install with it is easy to control, still fill a continuous U-shaped heater element 3 for most
It is excellent.
Such as Fig. 6, the length after the U-shaped bending of heater element 3 (at the top of from U-shaped closure bottom to two U-shaped open ends)
