Refrigeration-type notebook computer heat dissipation base
The utility model relates to a kind of computer radiator, refers in particular to a kind of air-cooled device that notebook computer is dispelled the heat with semiconductor chilling plate that utilizes.
In recent years, the microprocessor CPU chip is towards highly integrated, high microminiaturization and the fast development of high frequency direction.Constantly increase but when cpu performance improves constantly, also be accompanied by thermal value, had a strong impact on stability, reliability and the serviceable life of computing machine.And for notebook computer, because space constraint, the cooling mechanism of itself can not satisfy its some large softwares of operation and recreation at all, and the quality of heat radiation has directly influenced speed and stability that computer moves.So general notebook can dispose heating radiator with the Ministry of Revenue.
Present notebook PC radiator on the market generally adopts air cooling method to dispel the heat, and fan rotation forced air convective zone is walked heat.This heating radiator has simple in structure, cheap advantage, but heat-sinking capability is limited, and it is bigger influenced by ambient temperature, and certain effect is promptly arranged in winter, and summer radiating effect bad.Aspect the semiconductor refrigeration type notebook PC radiator,, make its two ends temperature difference in allowed band, so also have certain defective because the heating efficiency of semiconductor chilling plate necessarily requires large-scale heat radiator to be installed on the cooling piece hot junction much larger than its refrigerating efficiency.In view of the foregoing, develop and a kind ofly can utilize the air-cooled semiconductor refrigerating that can utilize again to be computer heat radiation, rotation speed of the fan is adjustable simultaneously, and the heat radiator for notebook computer that makes heating radiator be in optimum condition is necessary.
The utility model content
The technical matters that the utility model will solve provides a kind of refrigeration-type notebook computer heat dissipation base, and this heat dissipation base has solved and utilized air-cooled problem of dispelling the heat for notebook computer with semiconductor refrigerating simultaneously.
The technical matters that the utility model will solve is realized by following structure: refrigeration-type notebook computer heat dissipation base; It is flat box-like to be square; Be placed on the notebook computer below; Comprise panel, semiconductor chilling plate, radiator fan, cold house and circuit part, it is characterized in that: large and small two the panel fans that are used for to the computer inner blower are housed below the said panel, above the wherein big panel fan over against computer CPU; Be the cold house of processing below with the heat insulation foam plate; Inside and outside conduction cooling module and the heat conducting module of being equipped with respectively in cold house; Between conduction cooling module and the heat conducting module semiconductor chilling plate is installed; The cool and heat ends of said semiconductor chilling plate is connected with heat conducting module with the conduction cooling module respectively, fan is housed below the said conduction cooling module, and a side of said heat conducting module is equipped with radiator fan.
The utility model also comprises following structure: post the heat insulation foam bar around above the said panel.The cool and heat ends of said semiconductor chilling plate is connected with heat conducting module with the conduction cooling module and scribbles heat-conducting silicone grease between surface of contact.Described semiconductor chilling plate, fan all are connected with extraneous power supply with outlet through described circuit part.The front of said heat dissipation base is K switch 1, K2 and the rotation speed of the fan potentiometer of the work of installation and control semiconductor chilling plate respectively.The back dress outlet of said heat dissipation base also has hot-blast outlet.
The principle of work of the utility model: refrigeration-type notebook computer heat dissipation base is connected on the direct supply of 12V, and whether the work through K switch 1 control semiconductor chilling plate; The start and stop of K switch 2 control fans.Semiconductor chilling plate makes gas refrigeration in the cold house after the conduction cooling module is freezed, and has fan that cold wind is sent into computer again, and the fan on the conduction cooling module is used for cold wind is seen off, prevents conduction cooling module dewfall simultaneously.Radiator fan is used for hot-side heat dissipation on the heat conducting module, guarantees that the semiconductor chilling plate two ends temperature difference is in allowed band.Potentiometer is controlled rotation speed of the fan, guarantees to have in the cold house cold air of surplus.
The advantage of the utility model: refrigeration-type notebook computer heat dissipation base more can adapt to the computer work state, if when computer operation large software or recreation thermal value are very big, and available semiconductor chilling plate refrigeration, and cold wind sent into computer; When small-sized software or recreation thermal value are little, available air-cooled.Both save electric energy, and can reach good refrigeration again.

Like Fig. 1-shown in Figure 3, refrigeration-type notebook computer heat dissipation base is square flat box-like, is placed on the notebook computer below during use.Post heat insulation foam bar 2 around above the panel 1.5V and two panel fans of 12V 3,4 of being used for to the computer inner blower are housed below the panel 1, and wherein 12V panel fan 4 is top over against computer CPU; Be the cold house 6 of processing below with heat insulation foam plate 5.Cold house's 6 inside and outside conduction cooling module 7 and heat conducting modules 8 of being equipped with are respectively installed semiconductor chilling plate 9 between conduction cooling module 7 and the heat conducting module 8.The cool and heat ends of semiconductor chilling plate 9 is connected with heat conducting module 8 with conduction cooling module 7 respectively, scribbles heat-conducting silicone grease between its surface of contact.5V fan 10 is housed below the conduction cooling module 7, and a side of heat conducting module 8 is equipped with 12V radiator fan 11.Semiconductor chilling plate 9 all is connected with extraneous power supply with outlet 12 through circuit part with fan.The back dress outlet 12 of this heat dissipation base also has hot-blast outlet 13.
As shown in Figure 4, the front of this heat dissipation base is K switch 1, K2 and the rotation speed of the fan potentiometer 14 of 9 work of installation and control semiconductor chilling plate respectively.When K switch 1 closure; Semiconductor chilling plate 9 work; Gas is freezed in the cold house 6; Simultaneously 12V panel fan 4 begins the cold wind of cold house 6 is sent into the position of computer CPU on the panel 1, and 5V panel fan 3 is sent the low temperature wind of room temperature environment into other position of computer, and this state is used for the computer thermal value when big.When K switch 2 closures, K switch 1 closure, situation is identical.When K switch 2 closures, K switch 1 are broken off, have only 12V panel fan 4 and cold house's 6 fan work on the panel 1, the wind of ambient temperature is admitted to computer, and this state is used for the computer thermal value hour.K switch 1, K switch 2 are broken off simultaneously, and this heat dissipation base quits work.The rotating speed of the fan through regulating rotation speed of the fan potentiometer 14 control panels 1 and cold house 1, the control air output is to reach good result.
