Embodiment
Please refer to Fig. 1, be thermostat intraware configuration schematic diagram of the present invention.The ccontaining main frame equipment 2 of thermostat of the present invention, and when this main frame equipment 2 is made temperature test, in order to this main frame equipment 2 one isoperibols to be provided, including: a container 1 is used for ccontaining this main frame equipment 2; At least one circulating fan 12 is arranged at four corners in this container 1, and is electrically connected on this main frame equipment 2, forms a circulating current in this container 1; One heat-generating units is a bulb (not indicating), and it is arranged in this container 1, is electrically connected on this main frame equipment 2, provides a heating power in this container 1; At least one radiator fan 14 is arranged in this container 1, is electrically connected on this main frame equipment 2, as the heat radiation in this container 1; And a constant temperature control circuit 16, be electrically connected on this main frame equipment 2, control this heat-generating units and 14 actions of these radiator fans, in order to keep the temperature in this container 1.
With reference to figure 1, this container 1 of the present invention is the container of a sealing again.When the present invention makes temperature test at main frame equipment 2, utilize the rotation of these circulating fans 12 to allow the air of container 1 inside produce powerful air-flow, make container 1 inner every bit temperature equate, air-flow also becomes the gas wall one simultaneously, high temperature air is enclosed in container 1 inside does not make it to flow out.These circulating fans 12 begin to rotate after this main frame equipment 2 start-up temperature test, in order to carry out the convection current of container 1 inner air.This constant temperature control circuit 16 is a thermostatic control card, and can be plugged in this main frame equipment 2, by this main frame equipment 2 in order to control 14 actions of this heat-generating units and these radiator fans.In the above-mentioned explanation, this main frame equipment 2 is a motherboard.
The present invention also further includes at least one auxiliary circulation fan 18, is arranged in this container 1, and is electrically connected on this main frame equipment 2, this circulating current is imported this constant temperature control circuit 16, as the temperature control foundation of this constant temperature control circuit 16.In the above-mentioned explanation, this container 1 has one and penetrates hole (indicate) and be used for allowing the signal wire of main frame equipment 2 and power lead penetrate the hole by this being connected to an outside main frame testing of equipment machine (indicating), and carries out the test of main frame equipment 2 under certain hot environment by this main frame testing of equipment machine.
Again with reference to figure 1, after the test beginning, the heat energy that temperature in this container 1 can be produced along with the central processing unit on the main frame equipment 2 (CPU), internal memory (DDR), display card interface (AGP), power supply correlated parts, north bridge chips (NB) and South Bridge chip (SB) etc. and rising, the heat energy of adding the 20W that constant temperature control circuit 16 control heat-generating units (bulb) action provided also can be assisted and be heated, and promptly can reach design temperature (50 ℃ for example Celsius) in the about 5--10 of its rate of warming minute.When main frame equipment 2 temperature rise gradually, its inner hot-air can up run, but hot-air can run into the loam cake of container 1 and then have to run to the next door, and run into the circulating current that circulating fan 12 is produced this moment, and air-flow can be covered with whole container 1 to hot-air rapidly.When container 1 temperature inside surpasses the temperature set, then constant temperature control circuit 16 can rotate by these radiator fans 14 of control, in order to hot-air is discharged container 1, also controls this heat-generating units (bulb) simultaneously and stops heating.When container 1 temperature inside is lower than the temperature that sets, constant temperature control circuit 16 can stop operating by these radiator fans 14 of control, at this moment, the heat energy that central processing unit on the main frame equipment 2 (CPU), internal memory (DDR), display card interface (AGP), power supply correlated parts, north bridge chips (NB) and South Bridge chip (SB) etc. are produced can continue to provide thermal source to produce heating effect, when temperature was higher than design temperature, these radiator fans 14 began again to rotate.So constantly circulation is promptly in container 1 temperature inside can be constant at design temperature ± 1 ℃, to reach thermally equilibrated state.
Please refer to Fig. 2, be constant temperature control circuit synoptic diagram of the present invention.Constant temperature control circuit 16 utilizes the first input end of one first comparer U1 to be connected to one first temperature limitation circuit 162, and one second input end is connected to a temperature sensing circuit 166, and export these radiator fans 14 of a signal controlling in first output terminal, utilize one the 3rd input end of one second comparer U2 to be connected to this temperature sensing circuit 166 simultaneously, reach a four-input terminal and be connected to one second temperature limitation circuit 164, and export this heat-generating units of a signal controlling (indicating) in second output terminal.In the above-mentioned explanation, this first temperature limitation circuit 162 is connected in series to a reference potential VREF by two resistors (R1, R2).Simultaneously, this second temperature limitation circuit 164 is connected in series to this reference potential VREF by two resistors (R3, R4).Simultaneously, this temperature sensing circuit 166 is connected in series a resistor R 5 by a thermal resistor RT, and is connected to this reference potential VREF.
Cooperate Fig. 1, again with reference to figure 2, wherein this thermal resistor RT has the characteristic of a negative temperature coefficient, and meaning is promptly when environment temperature rises, the resistance value of itself can descend, otherwise, if when environment temperature descends, the resistance value of itself then can rise, for example, and the RT=4120 Ω when temperature is 50 ℃; RT=4258 Ω when temperature is 49 ℃.As shown in Figure 2, suppose resistor R 4=4258 Ω, resistor R 2=4120 Ω, and its resistance value of resistor R 1, R3 and R5 identical (embodiment is 10K Ω).After the test beginning, temperature in the container 1 is very low, therefore the resistance value of this thermal resistor RT can be greater than resistor R 4 and resistor R 2, so, according to voltage divider principle, the second input terminal voltage VC that is produced in the first comparer U1 is greater than first input end voltage VA, and the first comparer U1 was output as electronegative potential and was used for closing these radiator fans 14 this moment.Simultaneously, the 3rd input terminal voltage VC that the second comparer U2 is produced is greater than four-input terminal voltage VB, and the second comparer U2 was output as noble potential and was used for opening this heat-generating units (bulb) and generates heat this moment.
As described above, when container 1 temperature inside during greater than 49 ℃, the resistance value of thermal resistor RT can be between resistor R 2 and resistor R 4 (4258 Ω ≧ RT〉4120 Ω), so, according to voltage divider principle, the first input end voltage VC that the first comparer U1 is produced is still greater than the second input terminal voltage VA, these radiator fans 14 still cut out, but, the four-input terminal voltage VB that this moment, the second comparer U2 was produced is more than or equal to the 3rd input terminal voltage VC, second comparer U2 output this moment is used for closing the heating of this heat-generating units (bulb) by for noble potential transfers electronegative potential to.
As described above, when container 1 temperature inside during greater than 50 ℃, the resistance value of thermal resistor RT can be less than or equal to resistor R 2 (RT ≦ 4120 Ω), so, according to voltage divider principle, the first input end voltage VA that the first comparer U1 is produced is greater than the second input terminal voltage VC, the first comparer U1 is output as noble potential and is used for starting these radiator fans 14 to dispel the heat at this moment, the four-input terminal voltage VB that this moment, the second comparer U2 was produced is still greater than the 3rd input terminal voltage VC, therefore second comparer U2 output is electronegative potential still, is used for closing the heating of this heat-generating units (bulb).
So, when container 1 temperature inside is higher than the temperature of setting, thermal resistor RT in the constant temperature control circuit 16 can change its resistance value with environment temperature, and then compare computing by the resistance value (R2, R4) that the first comparer U1 and the second comparer U2 set, in order to start heat-generating units (bulb) heating, allow container 1 temperature inside accelerate promote, and make and under design temperature, carry out the startup of radiator fan 14 or close, in order to the balance temperature inside.

In the above-mentioned explanation, if during this temperature limitation value of the no show still of the temperature in this isoperibol, then the thermal source by this heat-generating units continues to heat (S104).Moreover if the temperature in this isoperibol utilizes the thermal source of this main frame equipment work to continue to heat (S110) during T ℃ of this working temperature value of no show still.And this temperature limitation value and this working temperature value differ 1 ℃ celsius temperature scale.Between T ℃ ± 1 ℃ of the working temperature value that the rotation of radiator fan and stopping can to make the temperature value in the isoperibol maintain to set, allow isoperibol can reach thermally equilibrated effect, carry out the test of main frame equipment under certain hot environment so that main frame testing of equipment machine (not indicating) to be provided.
In sum, the present invention is a kind of thermostat, is used for a ccontaining main frame equipment by a container, and when this main frame equipment is made temperature test, provides this main frame equipment one isoperibol.Be provided with at least one circulating fan in this container, these circulating fans are electrically connected on this main frame equipment, form a circulating current in this container.Simultaneously, in this container, also be provided with a heat-generating units and be electrically connected on this main frame equipment, in order to provide a heating power in this container, and at least one radiator fan is electrically connected on this main frame equipment, as the heat radiation in this container, and, one constant temperature control circuit, be connected in this main frame equipment, control the action of this heat-generating units and these radiator fans, in order to keep the temperature in this container.
