Description

The integrated miniature computer of low-power consumption low noise

Affiliated technical field

The utility model relates to a kind of integrated miniature computer, the little integrated miniature computer of fan noise when referring to have the low and work of computer Overall Power Consumption especially.

Background technology

The dynamo-electric brain of conventional desktop is divided into main frame and display, and main frame is connected with data line by VGA in the main frame or DIV interface with showing, makes display can cooperate host work.Along with the development of Computer Science and Technology and people improve day by day to the requirement of computer performance, the dynamo-electric brain performance of conventional desktop constantly promotes, its configuration constantly updates, frequency of operation as CPU and internal memory is more and more higher, the frequency of operation of the Front Side Bus between CPU and the internal memory is more and more higher, data rate is also more and more faster, and the integrated level and the function of south, north bridge chips are more and more higher, and the capacity of hard disk is increasing or the like.These progressive demands that satisfied people to a certain extent undoubtedly, yet some problems anxious to be solved have appearred in the thing followed, and are more and more higher as the computer power consumption, the thermal value of computer inside chip is increasing, and the fan noise during computer work is also increasing.

Power when working owing to CPU is along with the raising of performance increases, and the processing speed of CPU is more and more faster, therefore, when the general user uses computer, many times CPU need not work, if CPU moves by the power of normal operating conditions always, then the power of CPU consumption is quite big.Wasted a large amount of energy under the CPU idle condition, the current society more and more in short supply at the energy is difficult to tolerate.Simultaneously, because the raising of computer performance, the thermal value of computer inside chip is increasing, in order to make computer energy operate as normal steady in a long-term, brings into play its due effect and performance, and is more and more higher to the quality of materials and the performance requirement of heating radiator.Require the performance of fan of CPU also more and more higher, not only require it to have lower power consumption, and require its noise also should be lower, computer product only in this way could be accepted by consumers in general.

Yet traditional desktop computer computer is done to such an extent that be not fine in this respect, and the computer work performance has improved, and the power consumption of CPU and fan thereof is not effectively controlled.The CPU power consumption has also raise when improving performance, and in order to make CPU energy operate as normal steady in a long-term, its fan also must be followed CPU together with higher rotation speed operation, and thing followed cpu fan noise has also increased.These are that consumer institute is flagrant, fan noise problem especially, and nobody wishes to allow quiet work and living environment be subjected to noise jamming from computer.Yet, though notebook computer possesses the advantage of aspects such as energy-conservation and low noise, its price comparison costliness, under present economic condition, ordinary consumer still is difficult to bear.

Summary of the invention

Design the utility model purpose is exactly in order to address the above problem, a kind of integrated miniature computer of novel concept is proposed, this integrated miniature computer integrates main frame and display, in integrated computing machine, adopt the working method of notebook computer, the power consumption of reduction system, reduce system noise, reach energy-conservation and quiet purpose.Concrete technical scheme is as follows:

Adopt the notebook processor, VID0～VID6 pin by power supply chip (as ISL6262), obtain CPU corresponding work status information, processing by power supply chip inside, the voltage of relevant work state is provided to CPU after adjustment output pin UGATE1, UGATE2, PHASE1, the road filtering, accomplish that frequency and operating voltage adjust automatically, when load is light, move with lower operating voltage and frequency of operation, when load is heavier, recover its rated operational voltage and frequency of operation, do not influence the performance of system itself.Simultaneously, by the high-low level of PSI# pin, the number of phases of control power supply chip output circuit, because there is switching loss in chip in the process of voltage transformation, so the circuit output number of phases is after a little while, switching loss is little, to reach the effect of saving electric energy.

The utility model adopts novel fan control circuitry, Based Intelligent Control cpu fan rotating speed.When cpu power is low, also be that its thermal value is little, cpu temperature is low, and fan is with than slow-speed of revolution running or stall.When CPU recovered operate as normal, its fan was again by its rated power running, to satisfy the requirement of CPU heat radiation.Like this, because when computer CPU is in underload work or does not work, cpu fan and be in the slow-speed of revolution or stall is so the fan work noise is little.

Host power supply adopts the Temperature Control Type power supply, and the rotating speed of power supply fan changes with variation of temperature.Complete machine of the present utility model inner space is rather spacious, air hole is offered in side at main frame, allow the automatic convection current of its inner air and outer air just can solve the heat dissipation problem of inner other accessories of main frame, need not to install in addition case fan, thereby reduced the loss of energy, the noise problem of this respect does not just exist yet yet.

Embodiment

With reference to accompanying drawing 1 and Fig. 2, circuit structure provided by the utility model is explained embodiment of the present utility model below.

For a computing machine, CPU is its core, and its performance has determined the performance of whole loom to a great extent, and other accessory all turns round around it, therefore, reduces power consumption of processing unit as far as possible and will directly have influence on the power that total system consumes.For common desk-top dynamo-electric brain, know that by Fig. 1 power supply chip has increased the PSI# pin newly, by detecting its current potential, can know the power consumption state that CPU is current.During in the heavy duty duty, PS1# consumption pin is a high level at CPU, and power supply chip adopts the two-phase way of output to power to CPU, and output current is big, and carrying load ability is strong, to satisfy the needs of CPU when the heavy duty.As CPU during in underload or idle condition, the PSI# pin is a low level, and by the phase pwm control circuit in its powered-down chip, power supply chip adopts the single-phase circuit way of output to power to CPU, can satisfy the demand of CPU like this.Because in the need of work consumed power of power supply chip inner control circuit, metal-oxide-semiconductor, coil and electric capacity outside in the voltage transformation process also will lose part energy.Close a phase pwm control circuit, the energy of the inside and outside line loss of power supply chip has been saved a part of electric energy when just having reduced this phase pwm control circuit work.

The value of power supply chip VID0～VID6 in the conventional desktop machine is changeless simultaneously, promptly the operating voltage of CPU is maintained fixed constant after the start, and the value on the VID0～VID6 of circuit is variable in the utility model, by its variation, the dutycycle of control power supply chip reproduced pulse, thereby the height of the voltage that provides to CPU is provided, and promptly the operating voltage size of start back CPU can change with load variations, to reach energy-conservation effect.Show after tested, adopt this scheme after, computer complete machine power reduces significantly, can reach the power consumption levels of notebook computer.

With reference to the accompanying drawings 2, cpu fan of the present utility model adopts pwm circuit control, when cpu temperature was low, CPU sent corresponding signal to the IO chip, handled drawing relevant parameters through the IO chip internal, parameter is passed to BIOS chip internal software, through after the software processes, make that the input end ANPWM1 that connects the IO chip is a low level, Q1, not conducting of Q2, the fan no-voltage, stall.Similarly, when cpu temperature progressively raise, input end ANPWM1 voltage duty cycle after treatment increased gradually, the time of Q1, Q2 conducting increases gradually, the voltage that provides to cpu fan raises gradually, and rotation speed of the fan also just increases gradually, to satisfy the heat radiation requirement of CPU.In this way, make CPU when underloading or free time, the energy that its fan consumed greatly reduces.

The host power supply fan adopts the working method of Temperature Control Type, and host power supply is under system's heavy duty condition of work, and power consumption is many, power supply temperature height, and its rotation speed of the fan is also high, otherwise, then opposite.Like this, reduced the energy consumption of host power supply fan.Owing to the low-speed running or the stall of fan, fan noise is also just little, is to kill two birds with one stone simultaneously.

Louvre is offered in side at complete machine, the heat that other accessories of computer inside produce when working carries out exchange heat by louvre and external environment condition, just can solve heat dissipation problem, and do not need the other case fan of also will installing as the desktop computer that has, naturally also just saved electric energy, do not have fan, noise problem has not just existed certainly yet.

In the utility model, except CPU adopted the notebook mobile CPU, other hardware configuration still adopt the mode of desktop computer, and were therefore cheap than notebook computer on the price, but drawn the strong point of notebook computer, and power consumption can compare favourably with notebook computer.Littler at aspects such as energy consumption, noise, volume, weight than desktop computer, make things convenient for the user to move, this is that desktop computer is not available, so the utility model can satisfy some consumer demand, on the computer market one seat will be arranged.
