The voltage can change the fan voltage drastically after the voltage is amplified through a simple amplifying circuit. Moreover, the temperature-coefficient thermo-resistors are sued to control the rotary speed of the fan in order to appropriately adjust the rotary speed of the fan along with the ambient temperature. The utility model has the effects of effectuating an optimal heat exchange and prohibiting the noise.
Description
Technical field
The utility model relates to the quiet of a kind of computer-internal system and heat radiation integrated structure, and then can reach and significantly promote radiating efficiency, and can suppress benefit such as noise.
Background technology
With regard to the development trend of present computing machine miniaturization and, it has also made a noise to main frame in advanced countries such as America and Europes and has done standard control authentication.The noise source major part that mainly takes place with present main frame is from the fan of its inside, as the power supply unit fan, the CPU radiator fan and the radiator fan of generally bleeding, said fans is done the single high-revolving heat radiation and the action of bleeding when main frame is carried out running, therefore high rotating speed running just can produce a noise source down, can not change with peripheral temperature and adjust the required rotating speed of realistic temperature heat interchange, and the suitable power consumption of the lasting running of long-term energising also causes easily burns, shorten serviceable life, though event present stage main frame fan that computer-internal is assembled can reach the purpose of heat radiation, but fail to make its level of noise to reduce, do not met the development trend of present stage computing machine.
Summary of the invention
It is the defective of single rotating speed control that the purpose of this utility model is based on the inner institute of known main frame assembling fan, and present stage makes a noise to main frame and makes the demand of control, propose the quiet of a kind of computer-internal system and heat radiation integrated structure, be provided with utilizing on the industry.
The purpose of this utility model realizes by adopting following technological means, quiet and the heat radiation integrated structure of computer-internal provided by the utility model system is the power supply unit fan that main frame is mainly taken place noise source, set up temperature coefficient thermistor on the CPU radiator fan and the radiator fan of generally bleeding, to control its rotating-speed control circuit, its rotating speed can be changed with peripheral temperature do suitable adjustment, when carrying out running, main frame can keep high-revolving radiating efficiency, when not carrying out the running standby, main frame can not keep slow-revving general thermolysis, not only can reduce it noise problem takes place, also can increase its serviceable life simultaneously and reduce power consumption energy equivalence benefit; In addition, power supply unit of the present utility model is also adopted with right angle convection current air suction mode, makes the fan of its inner assembling allow the inner thermal source that produces of main frame do the heat exchange action of full blast directly corresponding to CPU radiator fan position.This novel the quiet of computer-internal system that can reach of event is done with integration with heat radiation, reaches the purpose that significantly promotes radiating efficiency and suppress noise.
The embodiment given below in conjunction with accompanying drawing will make further detailed explanation to structure of the present utility model, and the effect that makes it that its feature of the present utility model is reached has more clearly to be understood.

Embodiment
See also Fig. 1 to shown in Figure 5, the quiet and heat radiation integrated structure of the utility model computer-internal system mainly is to set up one group of temperature coefficient thermistor 4 formation of organizing at least on fan 11, the CPU radiator fan 2 of power supply unit 1 and the radiator fan 3 of bleeding.
Be to be equiped with two groups of temperature coefficient thermistor 4 on the fan 11 of this power supply unit 1 as shown in Figure 3 wherein, be to be equiped with one group of temperature coefficient thermistor 4 as shown in Figure 5 on this CPU radiator fan 2, bleeding on the radiator fan 3 as four shown in Figure 4 these is to be equiped with one group of temperature coefficient thermistor 4, and this temperature coefficient thermistor 4 is to strengthen the branch pressure voltage of circuit for controlling speed of fan, this branch pressure voltage can done to change significantly through simple amplifying return circuit to fan voltage, and then utilize temperature coefficient thermistor 4 to control the rotating speed of fan, do suitable adjustment to make rotation speed of the fan change with peripheral temperature.
As shown in Figure 1, this power supply unit 1 is to be installed on computer housing 5 tops to do heat interchange, be to be installed on the CPU of computer housing 5 internal host plates 6 to do heat interchange on this CPU radiator fan 2, and this this radiator fan 3 of bleeding is to be installed in to do heat interchange on computer housing 5 backboards, the fan 11 that install this power supply unit 1 inside and for example shown in Figure 2 is the big distinguished and admirable fan body of a 12CM, it is installed in power supply unit 1 inner below, and directly corresponding to CPU radiator fan 2 positions, and power supply unit 1 is exposed to the slotted eye 12 that the side system of computer housing 5 is penetrated with plural groups honeycomb kenel, make it form a right angle convection current air suction mode, simultaneously be to be equiped with one to arrange in pairs or groups mutually for a posistor 4 and a negative tempperature coefficient thermistor 4 on the fan 11, can provide fan 11 rotating speeds to temperature control, allow the inner thermal source that produces of main frame do the heat exchange action of full blast.
Therefore the utility model is on concrete enforcement, when main frame activates, the fan 11 of this power supply unit 1, CPU radiator fan 2 and the radiator fan 3 of bleeding are subjected to temperature coefficient thermistor 4 its rotating speeds of control to form a slow-speed of revolution, can reach the benefit of heat radiation and low noise.
When computer CPU was carried out full carrying and done, the fan 11 of this power supply unit 1, CPU radiator fan 2 and the radiator fan 3 of bleeding were formed by temperature coefficient thermistor 4 its rotating speeds of control all can keep high-revolving radiating efficiency.
