Abstract

The utility model relates to a random temperature control radiator for computer hosts. A host is provided with a CPU fan and two system fans to make the fans connected with a rotational speed sensing and controlling circuit, and then connected with a microprocessor; the microprocessor is caused to be connected with a temperature sensing element. An operating panel is arranged on the surface of the host, and different temperature values and fan speed with different numbers of stages are set through the operating panel, which drives the fan to enhance rotary speed when the CPU heats up due to work and exceeds the temperature set value by temperature sense of the temperature sensing element and the comparison of the microprocessor when the internal temperature of the host changes; then the effect of radiating following temperature control is obtained.

Description

Host computer with the temperature control heat abstractor

Technical field

The utility model relates to a kind of heat abstractor, especially a kind of can be with environment temperature with suitable adjusting rotation speed of the fan, improve radiating effect host computer with the temperature control heat abstractor.

Background technology

General host computer can produce intensification to a certain degree when working owing to CPU, therefore, the dealer establishes with a heat radiator and radiator fan in CPU usually, to constitute thermolysis, because the processing speed of CPU promotes day by day, cause existing radiator structure not apply and use, and owing to be an accommodation space in the casing of whole main frame, high temperature is mutual circulation in this space, though another system fan is arranged outwards distributes, but it is a fixed rotating speed, and because of forming convection action, so radiating effect is limited.

Summary of the invention

Fundamental purpose of the present utility model, provide a kind of host computer with the temperature control heat abstractor, make the radiator structure of main frame inside be able to change the rotating speed of fan, to improve its radiating effect with environment temperature.

Aforesaid heat abstractor in the forward and backward side of host computer, is respectively equipped with system fan with the formation convection current, and makes this two system fan and cpu fan be connected to a microprocessor, by the rotating speed of this microprocessor control fan.

Aforesaid heat abstractor is to make this microprocessor be connected in a temperature sensing element, for the temperature rise of sensing main frame inside, with the foundation as the control rotation speed of the fan.

Aforesaid religion thermic devices is to make this microprocessor be connected in a control panel of being located at the main frame surface, and the button on this panel can be set different temperature values and different rotating speeds.

Aforesaid heat abstractor is provided with the tachometer value of a LCD for displays temperature value and setting at described control panel.

Aforesaid heat abstractor comprises a rotating speed and detects a loop and a speed control loop, is connected to microprocessor and fan, for the rotating speed that detects and control fan.

Embodiment

Please consult Fig. 1, Fig. 2 simultaneously, the utility model mainly is to be provided with a fan 2 that places CPU1 in host computer 100, and the

system fan

3,4 that places the forward and backward side of main frame respectively, make these

fans

2,3,4 be connected to a rotating speed and detect a loop 5 and a speed control loop 6, and make these

loops

5,6 be connected in a microprocessor 7;

7 of this microprocessors are connected in a control panel 8 of being located at main frame 100 surfaces, in this control panel 8 button 81 are set, and via the LCD 83 that drives loop 82 controls;

One temperature sensing element 9 is located on CPU1 and the main frame 100, makes this induction element 9 be connected in microprocessor 7 via an analog/digital converter 91;

Combination by aforementioned components, the user can set different temperature values according to environment temperature by the button 81 on this control panel 8, and set each

fan

2,3,4 different rotating speeds is (according to present embodiment, system is respectively equipped with low section, the rotating speed of stage casing and high section), when main frame 100 actions, this temperature sensing element 9 is detecting CPU1 and main frame temperature inside constantly, be converted to input microprocessor 7 after the digital signal via analog/digital converter 91, do comparison mutually via this microprocessor 7 and the previous temperature value of setting, when the temperature of CPU1 is higher than set temperature value, the output control signal, change each fan 2 via

speed control loop

6,3,4 rotating speed makes rotating speed comply with the low of setting, in, high section improves one by one, to reach radiating effect, and make each

fan

2,3,4 according to different temperatures raising rotating speed, to reach purpose of power saving.

See also Fig. 3, it is the utility model preferred embodiments circuit diagram, as shown in the figure, one microprocessor 7 is connected in a comparer of being made up of U1C and peripheral element thereof, be connected in temperature sensing element 9 again, and its output terminal is except that being connected in a LCD 83, and the amplifier of forming via U1A, U1B, U1D and peripheral element is connected in

different fan

2,3,4, this microprocessor 7 is able to according to temperature and the rotary speed data set, when temperature rises or descend, the high and low rotating speed of each

fan

2,3,4 of appropriate change is to reach certain radiating effect.

In sum, the utility model is controlled the rotating speed of different fans with the temperature perceptive mode, makes the radiator fan following temperature rising of host computer change rotating speed, to improve radiating effect.
