Description

Electronics cooling and dehumidifying device

Technical field

The utility model relates to a kind of semiconductor refrigerating dehumidifier.

Background technology

The principle of semiconductor refrigerating dehumidifying is to adopt semi-conductive paltie effect, that is, under certain conditions, the one side of semiconductor refrigerating element refrigeration, another side heat release.So, can utilize semi-conductive this performance to design the refrigerated dehumidification device that a kind of life-span is long, reliability is high, noise is low.

In the prior art, be: at the low temperature side of semiconductor refrigerating element cooling is installed and is used for cooling off humid air with radiator (below general designation " cooler ") and dehumidifies as the design of PANASONIC electrician Co., Ltd. (seeing Japan special permission communique H8-296920).Constantly discharge the heat that cooling module gives out and in the heat release side heat release is installed with radiator (below general designation " radiator "), the structure of this semi-conductor dehumidifying device as shown in Figure 1.In this design, the cooler that is installed on semiconductor refrigerating element low temperature side is reduced to below the dew point temperature that flows through its surperficial humid air, thereby airborne steam is condensed and reaches the dehumidifying purpose.The cold air of process dehumidifying is directed into the radiator of release end of heat again, and radiator is cooled off.Afterwards, dry air is discharged the dehumidifier casing through fan, thereby finishes dehumidification process.In electronics dehumidifier shown in Figure 1, the flow direction of semiconductor refrigerating element and air is perpendicular.The higher humid air of the temperature that sucks from air inlet enters from the top of cooler fin, reaches dew-point temperature and dehumidifying after the cooling through a segment distance.The condensate water that dehumidifying produces flows along the direction opposite with air, and promptly the fin root from cooler flows to the top, falls into the condensate water gatherer afterwards.The shortcoming of this method is: in the process that condensate water flows down, condensate water covers whole fin surface with the form of liquid film, especially the thickness of liquid film maximum on fin top.Like this, the heat conduction between fin and the air need be passed thickness of liquid film, thereby has greatly increased heat transfer resistance.This process as shown in Figure 2.

Summary of the invention

The purpose of this utility model is the architecture advances that proposes a kind of electronics cooling and dehumidifying device of based semiconductor refrigeration, and this dehumidifier can avoid condensate water to form liquid film on cooler fin surface, thereby improves its effect on moisture extraction.

The technical solution of the utility model is to propose on the basis to the existing existing Study on Problems analysis of semi-conductor dehumidifying device, this dehumidifier has the general structure of semi-conductor dehumidifying device, promptly has a semiconductor refrigerating element, at its low temperature side cooler is installed, in its heat release side radiator is installed, and comprise supply unit, fan, control device, condensate water receiving system, drainage arrangement and dehumidifier casing, it is characterized in that forming on the radiating fin of said cooler many structures that can play guide functions.This structure can be and is engraved in the lip-deep guiding gutter of radiating fin; Also can be the water conservancy diversion lug, nib that on the radiating fin surface, forms; Also can be for playing the structure of other structural forms of guide functions.

The operation principle of the utility model cooler is: pass through described flow-guiding structure (guiding gutter or water conservancy diversion lug, nib) at the condensation water that produces on the cooler fin under capillary effect, then at the synergy lower edge of gravity and capillary force flow-guiding structure to dirty, fall into fluid collection device then.

Advantage of the present invention is: the coagulating liq that produces on the cooler fin is directed to flow-guiding structure to dirty, and makes other surfaces of fin be in drying regime all the time, thus, is in good heat convection state between fin surface and the air all the time.Thereby improve effect on moisture extraction greatly.

The specific embodiment

Embodiment one

Fig. 1 is the structure of conventional semiconductor refrigerated dehumidification device, this dehumidifier has a semiconductor refrigerating element 1, at its low temperature side cooler 2 is installed, in its heat release side radiator 3 is installed, and comprise supply unit 4, fan 5, control device, condensate water receiving system 6, drainage arrangement and dehumidifier casing 7, humid air flows into from air inlet 8, and the dry air after dehumidifying is discharged from exhaust outlet 9.Fig. 2 is the structure chart of the cooler 2 among Fig. 1, and wherein 21 is the cooler base plate, and 22 is the cooler fin.To be humid air stream form the schematic diagram of liquid film 25 through the cooler fin of Fig. 2 to Fig. 2 on the fin surface, and the arrow indication is an air flow.

Present embodiment (Fig. 7) be on above-mentioned basic structure, to make improvements, the structure of its cooler 2 is carved with many guiding gutters 23 as shown in Figure 4 on the surface of cooling fin 22, Fig. 5 has shown the shape of described water conservancy diversion conduit.

The operation principle of whole dehumidifier is: the humid air that comes from air inlet enters two spaces between the adjacent radiating fin along the direction perpendicular to the cooler base plate, along the radiating fin heat exchange of journey and cooler and obtain cooling off.Reach dew-point temperature and begin dehumidifying during at this air near the root of radiating fin.At the root and the passage place of cooler radiating fin, the temperature of air is further reduced, thereby reaches good dehumidification effect.The condensation water that dehumidifying produces flows to water conservancy diversion conduit bottom along aforesaid water conservancy diversion conduit, and the dry air after the dehumidifying is then discharged by the passage on the cooler base plate.

Then, this cold air enters the radiator bottom by the passage on the radiator base plate.Because radiator base plate place temperature is higher, and the speed of cold air is higher than speed between the radiator fin herein, so radiator is well cooled off.Dry air then obtains good heating.Get rid of dehumidifier from the dry air that radiator comes out through passing through fan, thereby finish dehumidification process.
