Abstract
The utility model relates to a CPU refrigerator with an automatic temperature controller and an alarm device, which comprises a fan and a radiator. The fan is fixed on the tooth tip of the radiator by screws. The utility model is structurally characterized in that one side of the radiator is fixed with a control circuit board; the outer side at the bottom of the radiator is fixed with a refrigerating chip; the inner side of a ceramic chip on the cold side is welded with a thermistor Rt between the cold side and the hot side of the refrigerating chip. The utility model has the advantages of reasonable and compact structure, good constant temperature effect and high automation level.
Description
The utility model relates to chiller, especially can be temperature automatically controlled and the CPU refrigerator of reporting to the police, be used in particular in the computing machine cooling to central processing unit (CPU).
Generally adopt blower fan to add heating radiator to the cooling of CPU in the computing machine at present, but to summer, temperature still is too high on time one lead aircraft, influence the job stability of computing machine, the modus vivendi that people take has the power of opening cabinet, enlarging heating radiator or increasing blower fan, and said method not only bothers, influences outward appearance but also accounted for limited usage space more.
The purpose of this utility model is to utilize the principle of conductor refrigeration that the CPU refrigerator that a kind of energy is temperature automatically controlled and report to the police is provided, and reaches compactness rational in infrastructure, good constant-temperature effect, automaticity height.
The purpose of this utility model is achieved through the following technical solutions: the temperature automatically controlled and CPU refrigerator of reporting to the police, contain blower fan, heating radiator, blower fan is by the crown end of screw retention at heating radiator, its design feature is that a side of heating radiator is fixed with control circuit board, the bottom outside of heating radiator is refrigerating sheet fixedly, between the cold and hot surface of refrigerating sheet, the inboard of huyashi-chuuka (cold chinese-style noodles) potsherd is welded with a thermistor Rt.
Control circuit board described in the utility model mainly comprises thermistor Rt, operational amplifier U
1, triode V
1, V
2, luminotron D, semiconductor cooler TE, alarm BZ, thermistor one termination power, another termination amplifier U
1In follower U
1-1Anode, its negative terminal meets comparer U
1-3Negative terminal, follower U
1-1Output termination comparer U
1-2Negative terminal, comparer U
1-2Output terminal sending and receiving light pipe D and by triode V
1And V
2The on-off circuit of forming, refrigerator TE one end and triode V
2Emitter join other end ground connection, comparer U
1-3Output device BZ taking alarm.
Post the insulation sheet around the back side of heating radiator described in the utility model, the refrigerating sheet.One side of described refrigerating sheet has three leading foots, and one of them is the leading foot of thermistor Rt.
Advantage and good effect that the utility model is compared with prior art had are: compactness rational in infrastructure does not increase the volume of blower fan and heating radiator; Good constant-temperature effect, automaticity height, when cpu temperature surpassed 40 ℃, refrigerator TE began refrigeration work, when cpu temperature was reduced to 30 ℃, refrigerator TE closed work, if refrigerator breaks down, when the temperature of CPU was increased to 70 ℃, alarm BZ piped, and reminded the user to take measures.
To and contrast accompanying drawing by embodiment below specifies the utility model:
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the rear view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Fig. 4 is the electrical schematic diagram of the utility model embodiment.
As shown in the figure, present embodiment is made up of blower fan 1, heating radiator 2, control circuit board 3, refrigerating sheet 4, insulation sheet 5, gib screw 6, joint pin 7.Blower fan 1 usefulness screw 6 is fixed on the crown end of heating radiator 2, pass through fixedly control circuit board 3 of joint pin 7 in a side of heating radiator, the refrigerating sheet 4 of the bonding rectangle in the back side of heating radiator, folder has buried a thermistor between the cold and hot surface of refrigerating sheet, the folder method of burying is the quick resistance R t of the inboard welding heat of huyashi-chuuka (cold chinese-style noodles) potsherd at refrigerating sheet, posts insulation sheet 5 around the refrigerating sheet, and refrigerating sheet 4 has three leading foots by a side of circuit board, and being welded with the connection lead, the pin in the middle of it is the leading foot of thermistor Rt.
The principle of work of refrigeration control is: when cpu temperature surpassed 40 ℃, thermistor Rt resistance diminished, and the d point voltage raises, follower U
1-1Output terminal b point voltage also raise i.e. comparer U
1-2Cathode voltage raise comparer U then
1-2Output level e point reduce luminotron D and triode V
1, V
2Conducting, refrigerator TE work, when CPU was cooled to below 30 ℃, the resistance of thermistor Rt increased, and the d point voltage reduces, follower U
1-1Output voltage also reduce comparer U
1-2Output level increase, when the e point voltage high during to setting value; Luminotron D and triode V
1, V
2End, refrigeration TE quits work, and so goes round and begins again; If refrigerator breaks down can not refrigeration the time, the b point voltage is comparer U
1-3Negative pole input voltage when being increased to certain value, U
1-3Output low level, alarm BZ conducting gives the alarm.
