Abstract

An automatic heating unit for personal computer includes an instruction save circuit that receives a turn-on signal from a power switch of the personal computer (PC) to thereby drive a temperature sensing circuit to sense an ambient temperature inside the PC. When it senses the ambient temperature is too low to allow normal computer booting, the temperature sensing circuit outputs a heating signal to drive a heating circuit to heat an interior of the PC. Otherwise, the temperature sensing circuit outputs a booting signal to enable a booting circuit to supply power to a mainboard of the PC.

Claims

1. An automatic heating unit for PC, comprising:

an instruction save circuit capable of receiving a turn-on signal from a power switch of a PC;

a temperature sensing circuit driven by the instruction save circuit having received the signal of turned-on PC power switch to sense an ambient temperature inside the PC; and

the temperature sensing circuit outputting a heating signal when the sensed ambient temperature is too low to allow normal computer booting, or a booting signal when the sensed ambient temperature is normal for computer booting;

a heating circuit capable of receiving the heating signal from the temperature sensing circuit to thereby become ON to start heating; and

a booting circuit capable of receiving the booting signal from the temperature sensing circuit to thereby allow power to be supplied to a mainboard of the PC.

2. The automatic heating unit for PC as claimed in claim 1, wherein the instruction save circuit consists of a diode and a capacitor.

3. The automatic heating unit for PC as claimed in claim 1, wherein the temperature sensing circuit consists of a temperature sensing resistor, a resistor, and two inverters.

4. The automatic heating unit for PC as claimed in claim 1, wherein the heating circuit consists of a heater and a field effect transistor.

5. The automatic heating unit for PC as claimed in claim 4, wherein the heater is arranged on the mainboard of the PC.

6. The automatic heating unit for PC as claimed in claim 4, wherein the heater is arranged in a case of the PC.

7. The automatic heating unit for PC as claimed in claim 1, wherein the booting circuit consists of a resistor and a field effect transistor.
