Abstract

The utility model designs a computer casing capable of keeping constant internal temperature. A closed loop is formed between a power supply box and a casing body of the closed casing through an air return duct. A semiconductor cooling chip arranged in the utility model cools the passing air in the loop in the energized cooling work, and the cold air is sent the interior of the casing by an air extracting fan to achieve the purpose of cooling the interior of the casing. The utility model adopts a computer single-chip microcomputer to automatically control the temperature in the closed casing, and therefore, the closed casing can work in an appropriate temperature to prevent overheating hardware, such as a CPU, a hard disc, etc. and prevent dust from intruding simultaneously.

Description

The closed computer cabinet of constant temperature

The utility model designs a kind of improvement of PC cabinet, specifically a kind of computer housing that can keep constant built-in temperature.

Hardware such as the mainboard, hard disk, memory bar and the power supply that include CPU, CD-ROM drive, floppy drive are housed in the mainframe box of existing individual PC usually, wherein CPU, hard disk, power supply etc. all are heater members, and these hardware of computer all need at a certain temperature could operate as normal, the too high faults such as deadlock that cause easily of temperature, particularly hard disk temperature is too high or cold excessively, the read-write mistake is caused in the capital, causes file or loss of data.And existing computer generally all is that radiator fan is housed on CPU, makes CPU temperature in the process of work be unlikely too high, so just must have many fresh air inlets on the cabinet.And computer is in the long-term process of using like this, and dust will accumulate in the cabinet from these holes, can influence the operate as normal of each parts equally.So existing computer case radiation and dustproof problem can not solve simultaneously.

The purpose of this utility model is the closed computer cabinet of a kind of constant temperature of design, and it adopts the mode of semiconductor refrigerating, and airtight cabinet can be worked under a more suitable temperature, prevents that hardware such as CPU, hard disk are overheated, prevents the intrusion of dust simultaneously again.

The technical solution of the utility model is: the closed computer cabinet of a kind of constant temperature, it is characterized in that casing seals, be provided with a dividing plate in the bottom of cabinet, be provided with a return air conduit between the power pack of cabinet and the described dividing plate, power pack and cabinet inside also have return air inlet; The semiconductor refrigerating assembly is installed in the refrigeration cassette of a sealing under the dividing plate, the chill surface of semiconductor refrigeration chip is communicated with the top of cabinet, one of heat production faces down, an exhaust fan is housed between described refrigeration cassette and the top cabinet, the refrigeration cassette bottom be heat-dissipating space, respectively have air inlet and air outlet before and after on the cabinet herein, be used to discharge the heat that the work of semiconductor refrigerating assembly produces.

Like this, in cabinet, formed the loop of a sealing between power pack-return air conduit-refrigeration cassette-main box.Semiconductor refrigeration chip is in energising during refrigeration work, with flowing through its air cooling in the loop, by exhaust fan cold air sent into cabinet inside,, reach and make the cabinet inside cooling purpose.Simultaneously, the heat that the refrigerating chip radiating surface produces looses heat outside machine by inlet and outlet in the lower space of dividing plate.Whether in the operating circuit of refrigerating chip, temp probe is passed to single-chip microcomputer with the temperature signal of detected cabinet inside, worked by the Single-chip Controlling semiconductor refrigeration chip, and show relevant temperature information on display screen.

Computer housing of the present utility model adopts semiconductor refrigerating technology, adopts computer single-chip microcomputer A.T.C in the cabinet of sealing, has both solved the too high problem of temperature in chassis, can prevent dust again, and each hardware of computer can be worked in a stable environment.

Fig. 1 is the structural representation of the closed computer cabinet of this constant temperature.

Fig. 2 is the working circuit diagram of the semiconductor refrigeration chip that adopts of this cabinet.

Describe structure of the present utility model in detail below in conjunction with accompanying drawing.

As shown in Figure 1, the casing 1 of this computer housing seals.The bottom of cabinet 1 is provided with a dividing plate 3, is provided with a return air conduit 5 between the power pack 2 of cabinet and this dividing plate 3.The semiconductor refrigerating assembly is installed in the refrigeration cassette of a sealing under the dividing plate.This cooling assembly comprises semiconductor refrigeration chip, computer single-chip microcomputer, temp probe, relay and display screen.An exhaust fan 6 is housed between this refrigeration cassette and the top cabinet, and this exhaust fan constantly is evacuated to the air in the refrigeration cassette its top cabinet.

The heat production of semiconductor refrigeration chip faces down, and has air inlet 8 and air outlet 9 on the cabinet under the dividing plate, and it is in order to quicken heat radiation that pressure air draft electric fan 7 is housed on diffusing wind passage.

Fig. 2 is the circuit diagram of this cabinet semiconductor refrigeration system.The civil power of 220V becomes 12V by transformer, rectification circuit conversion back, is becoming the 12V DC voltage to use for complete machine after rectification, filtering.Single-chip microcomputer, temp probe, relay and display screen are formed the temperature control assembly.Temp probe is sent to single-chip microcomputer with the temperature signal of cabinet inside, and whether single-chip microcomputer works according to set temperature control semiconductor refrigeration chip, and demonstrates associated temperature on display screen.
