Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
What the utility model disclosed is a kind of constant temperature refrigerator based on dry ice sublimation principle, as shown in Figures 1 to 4, is preferred embodiment of the present utility model.Described refrigerator is provided with dry ice raw material cabin 6 and material storage room 15 in casing, and this dry ice raw material cabin 6 is positioned at the top of material storage room 15.This dry ice raw material cabin 6 is provided with raw material cabin lid 1, can arrange sealing gasket 2 between the two.This material storage room 15 is provided with material storage room's door 12, also can arrange sealing gasket 13 between the two.Baffle central position between described dry ice raw material cabin 6 and material storage room 15 has through hole 17, fan 10 is provided with in this through hole 17, the top of this through hole 17 is provided with airscoop shroud 9, this airscoop shroud 9 has some apertures 91, the effect arranging some apertures 91 can make gas pass through on the one hand, can prevent trash ice from falling in material storage room 15 on the one hand.Described refrigerator is also provided with the temperature controller 4, power supply 7 and the temperature sensor 16 that is arranged in material storage room 15 that are electrically connected to each other.
Further, described temperature sensor 16 can be arranged on the central authorities bottom material storage room 15.The object of such setting found through experiments, and temperature temperature in whole material storage room 15 of this position is minimum, therefore temperature sensor 16 is arranged on minimum temperature position, the temperature in the whole material storage room of control that can be more convenient.Identical, also temperature sensor 16 can be arranged on the maximum temperature position of material storage room, the same like this temperature can well controlling material storage room.By experiment and theory analysis, concerning the utility model, above the corner of material storage room 15, temperature is the highest.
The below of described through hole 17 can arrange an air leaving cover 11 further, and this air leaving cover 11 extends in material storage room 15, it is densely covered with a lot of aperture 111.Arrange the air leaving cover of this structure, the cryogenic carbon dioxide gas that fan can be made to blow out equably to bottom and surrounding diffusion, thus makes refrigeration more even.
Can arrange circulating line 8 in described dry ice raw material cabin 6, the lower end of this circulating line 8 communicates with material storage room 15, and what upper end open was positioned at dry ice raw material cabin 6 leans on tip position.After circulating line 8 is set, dry ice gas can be enable better to enter material storage room 15.And the upper opening of circulating line 8 is set to dry ice raw material cabin 6 close to tip position, then when dry ice sublimation produces carbon dioxide, heavier gas can not be sunk to the material storage room of lower floor by the opening of circulating line 8, better can control the flow of dry ice gas.In order to make the gas uniform of backflow, a circulating line 8 can be respectively set in four of dry ice raw material cabin 6 corner.
The utility model can also arrange touch-screen 5 further, in order to display and adjustment design temperature.Attractive in appearance in order to overall appearance, in dark lattice 3 that described temperature controller 4, power supply 7 and touch-screen 5 can be arranged on refrigerator casing.
Operation principle of the present utility model is: switch on power 7, puts into appropriate dry ice, touch-screen 5 is arranged temperature required in upper strata dry ice raw material cabin 6.When temperature sensor 16 senses temperature in refrigerator storage chamber 15 higher than design temperature, the temperature controller 4 controlled in dark lattice 3 exports, and fan 10 rotates.Dry ice and fan 10 separate by airscoop shroud 9, then the cryogenic gas that dry ice sublimation in dry ice raw material cabin 6 produces is sent in material storage room 15 by fan, when gas blows out via air leaving cover 11, cryogenic carbon dioxide gas will uniformly to four sides blowout, make the gas entering material storage room 15 more even, the gas of material storage room 15 is got back in dry ice raw material cabin 6 by circulating line 8 again, forms a circulation.And when temperature sensor 16 temperature sensed in material storage room 15 reaches design temperature, then signal being sent to temperature controller 4, then temperature controller 4 controls fan 10 and stops operating.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model to be imposed any restrictions, therefore the change in every case done according to claim of the present utility model and description or modification, all should belong within scope that the utility model patent contains.
