Abstract
The utility model relates to a remote control fan for a computer host, which is mainly provided with a microprocessor in the computer host, and the microprocessor is connected with a rotational speed and speed control circuit which is connected with different system fans and CPU fans. The microprocessor is connected with a CPU temperature sensing circuit, an LCD display, an external remote controller and a remote controller to cause the temperature of the CPU and the rotational speed of each fan to be displayed on the LCD display in the front of the housing of the computer host; moreover, the rotational speed of the fan can be regulated and controlled automatically according to different temperatures, or the action of each fan is controlled by the external remote controller.
Description
Technical field
The utility model relates to the fan of host computer, refer to especially a kind of can be by external remote control and can be according to the remote control fan of the host computer of the variation auto-control rotation speed of the fan of different temperatures.
Background technique
The main frame of general computer is that the heat that produces when making work is distributed, usually in casing, be provided with one or more fan, when computer work, the temperature in the casing can be reduced, to keep the normal operation of computer, because the fan of host computer all adopts fixed design, can't vary with temperature its different rotating speed of regulation and control, more can't be controlled by the outside.Therefore, the rotation that known fan can only not stop behind booting computer, not only power consumption and possibility reduce its working life because of continuing to run up, and be not ideal enough really.
Summary of the invention
Main purpose of the present utility model is to provide a kind of remote control fan of host computer, and it can be controlled by the outside, rationally regulates and control the rotating speed of fan according to the variation of its inside temperature, can make more power saving and can reduce the dry sound of fan, improve its working life of fan.
For reaching above-mentioned purpose, the remote control fan of a kind of host computer of the present utility model, mainly be provided with a microprocessor in host computer, this microprocessor is connected to rotating speed and picks up and know control loop and speed control loop, and these loops are connected in different system fan and cpu fan; This microprocessor also is connected with a LCD display; It is characterized in that:
This microprocessor connects an external remote and a remote control unit again, by an external remote transmit, by after the remote control unit received signal, the keying of each fan of auto-control and rotating speed.Wherein: described microprocessor is connected with an A/D converter and a cpu temperature perception circuit again, by the temperature variation of this perception circuit detecting CPU, complies with this temperature variation and the rotating speed of each fan of auto-control.
Described microprocessor also connects a button, a LCD drives a loop and a LCD display, and LCD display is located at casing the place ahead of host computer, and can be by external action of pressing the key assignments fan.
Because this microprocessor connects an external remote and a remote control unit, and by an external remote transmit, this remote control unit received signal, but so the keying and the rotating speed of auto-control each fan, make host computer have more practicability and have more hommization.
In addition, the remote control fan of this host computer also is connected with an A/D converter and a cpu temperature perception circuit, detects the temperature variation of CPU by this perception circuit, but complies with the rotating speed of this each fan of temperature variation auto-control, make more power saving of host computer, and the working life that can improve fan.
Again, the microprocessor of the remote control fan of this host computer connects a button, a LCD drives a loop and a LCD display, and LCD display is located at casing the place ahead of host computer, except the considerable rotating speed of looking its variation of temperature, each fan, also can make whole host computer have more practicability by external action of pressing the key assignments fan.

Embodiment
For to the purpose of this utility model, technical characteristics and effect thereof can have and further understand and be familiar with, and lift a preferred embodiment now, and conjunction with figs. are described in detail as follows:
Shown in Fig. 1,2, a kind of remote control fan of host computer, mainly in host computer 1, be provided with a microprocessor 11, this microprocessor 11 is connected to rotating speed and picks up and know control loop 12 and speed control loop 13, and makes these loops 12,13 be connected in different system fan 14,15 and cpu fan 16;
This microprocessor 11 also is connected with an A/D change-over circuit 17, and this circuit 17 is connected with a cpu temperature perception circuit 18, a LCD and drives loop 19 and LCD display 20, and a remote controller 21, a light-emitting diode display 22, button 23.
During combination, (high frequency, infrared rays etc.) can be transmitted by the remote controller 2 of these host computer 11 outsides, after making inner remote control unit 21 received signals, control the fan 14,15 of each system and the keying of cpu fan 16 respectively, and set its rotating speed separately, make host computer 1 have more hommization, more have practical value.
Wherein each rotating speed detects the rotating speed that 12 of control loops can be detected fan 14,15,16, and be shown in LCD display 20, so that knowing to see, the user looks, and can regulate the rotating speed of fan according to the actual conditions of rotating speed, temperature, moreover, be located at cpu temperature perception circuit 18, then can be after recording variation of temperature, processing through microprocessor 1, automatically control the rotating speed of fan 14,15,16 again by speed control loop 13, make each fan can comply with different its rotating speeds separately of temperature adjusting, reach purpose of power saving, and improve the working life of fan.
This microprocessor 11 also is connected with a fault-detecting circuit 31 and a buzzing alarming circuit 32, whether is in normal state so that detect the running of whole device automatically, and can give the alarm with buzzing alarming sound when appearance is unusual.
Referring to shown in Figure 3, LCD display 20 of the present utility model is located at casing the place ahead of host computer 1, except the considerable rotating speed of looking its variation of temperature, each fan, also can set the action of fans by external button 23, make whole host computer 1 have more practicality, have more hommization.
The above only is the utility model one preferred embodiment; be not to limit practical range of the present utility model with this; such as under spirit of the present utility model and principle; that has done various differently changes and modifies, and all should be covered by within the patent protection category that these claims define.
