Abstract

The utility model provides an automatic heating device of a personal computer, which mainly uses an instruction storage circuit to receive the start-up action signal of a computer power switch, and then outputs an action signal and a temperature sensing circuit to acquire the ambient temperature within the computer. A heating signal is output when the sensed ambient temperature is too low, in order to drive a heating circuit to heat the interior of the computer. When the temperature sensing circuit percepts the ambient temperature in the computer is normal, a start up signal is output to drive a start up circuit to connect the computer motherboard with power supply.

Description

The automatic heating apparatus of personal computer

Technical field

The utility model relates to a kind of automatic heating apparatus of personal computer, refers to a kind of start under extremely low temperature especially, and computing machine can be warmed to the heating apparatus that normal temperature is just started shooting voluntarily automatically.

Background technology

The normal operation circumstances temperature of general on the market computing machine, mostly all between 0 ℃～45 ℃, but some country's indoor environment temperatures in winter are arranged all between-20 ℃ to-30 ℃ degree, thus, hard disk in the main frame, electrochemical capacitor, fan, CDROM .... wait the part that oil, water composition are contained in inside all to have the situation that freezes, general computing machine start is many under environment like this can't operate as normal.

In the face of this kind situation, the more common practice is to increase indoor temperature, uses the environment temperature that increases computer-internal in the lump, to eliminate the aforementioned situation that freezes and can't work because of oil, water; Yet the whole indoor vast space of heating provides the demand of computer booting, value-for-money not after all, and required time is also more permanent, is difficult to satisfy everything requirement fast of modern.

The utility model content

Because existing personal computer is started shooting down in low temperature environment above-mentioned puzzlement is arranged, at those shortcomings, fundamental purpose of the present utility model is to provide a kind of automatic heating apparatus of personal computer, when it is started shooting under extremely low temperature in computing machine, can after being warmed to the temperature of the work of being suitable for automatically, computer-internal just start shooting voluntarily, with usefulness and the inner device operate as normal thereof of effectively guaranteeing computing machine.

The utility model is for reaching above-mentioned purpose and effect, its practiced technological means comprises: a save command circuit, can accept the boot action signal of a computer power switch, drive following temperature perception circuit again: a temperature perception circuit, but the environment temperature in this computing machine of perception is crossed when low in this environment temperature, exportable one signal of heating, and in environment temperature just often, then export a start signal; One heater circuit can be accepted the heating signal of this temperature perception circuit and switches on and heat; One boot-strap circuit can be accepted the start signal of this temperature perception circuit and the power supply of conducting computer main frame panel.

The beneficial effects of the utility model are, utilize the automatic heating apparatus of a kind of personal computer of the present utility model, can be under the lower situation of environment temperature, can make computer-internal be warmed to just start voluntarily after the temperature of the work of being suitable for automatically, can effectively guarantee the usefulness of computing machine and the operate as normal of inner device thereof rapidly.

Embodiment

Fig. 1 is a feasible square circuit diagram of the present utility model, can clearly find out by this figure, the utility model mainly comprises: save command circuit 1, temperature perception circuit 2, heater circuit 3 and boot-strap circuit 4 etc. are partly, wherein this save command circuit 1 can be accepted the boot action of a computer power switch 5, and drive following temperature perception circuit 2, but and this this computing machine of temperature perception circuit 2 perception in environment temperature, cross when low in this environment temperature, exportable one signal of heating, and in environment temperature just often, then export a start signal, heater circuit 3 can be accepted the heating signal of this temperature perception circuit 2 and switch on and heat, and 4 of boot-strap circuits can be accepted the start signal of this temperature perception circuit 2 and the power supply of conducting computer main frame panel;

In above-mentioned each circuit structure, this save command circuit 1 can be made up of a diode D1 and a capacitor C 1, temperature perception circuit 2 can be made up of a thermistor RT1, a resistance R 2 and two phase inverter u1, u2, heater circuit 3 can be made up of a heater H R1 (can be arranged on the motherboard or computer housing in) and a field effect transistor Q1, and boot-strap circuit 4 then can be made up of a resistance R 3 and a field effect transistor Q2; The action of its integral body is as follows: behind computer power switch 5 turn-on power VCCSB, the capacitor C 1 of this save command circuit 1 of directly-chargeable, its current potential is raise be HI, at this moment, the thermistor RT1 of temperature perception circuit 2 can respond to the environment temperature in this computing machine, when temperature is crossed when low, the dividing potential drop that thermistor RT1 and resistance R are 2 is lower, can't make the field effect transistor Q2 conducting of boot-strap circuit 4, at this moment, the field effect transistor Q1 of heater circuit 3 is subjected to the HI current potential of capacitor C 1 and conducting, make its heater H R1 energising heating, the environment temperature in computing machine rises, this field effect transistor of the enough conductings of dividing potential drop Q2 that this thermistor RT1 and resistance R are 2, but make the power supply VCCSB of switch J2 conducting motherboard, computing machine gets final product normal operation.

From the above mentioned as can be known, the automatic heating apparatus of the utility model personal computer has really in the start down of utmost point low temperature environment, and computing machine can be warmed to the effect that normal temperature is just switched on and operated voluntarily automatically, has really had the usability on the industry.

In sum, though the utility model discloses above content with preferred embodiment, but be not in order to limit the scope that the utility model is implemented, any those skilled in the art, in not breaking away from spirit and scope of the present utility model, when doing a little change and retouching, promptly all equalizations of doing according to the utility model change and modify, and should be the utility model claim and contain.
