After the semiconductor refrigerator energizes and operates, the temperature of the cold end is reduced rapidly, a flat-plate warping sheet of the quenching device is arranged in the inner liner and has large and effective heat exchange area, water which is contacted with the flat-plate warping sheet increases the density when the temperature is reduced, and the flat-plate warping sheet is sunk rapidly. Uncooled water at the lower layer in the inner liner raises, the water in the inner liner forms the high-speed convection, and the purposes of high refrigerating speed, high efficiency, large refrigerating capacity and energy saving performance are reached finally.

Description

High efficiency semiconductor refrigeration water dispenser

The utility model is about a kind of conductor refrigeration water dispenser.

Since semiconductor cooler comes out, it is applied in the build that can substitute mechanical commprssor on the refrigeration water dispenser and reduce water dispenser and has reduced manufacturing cost, yet there is following problem in the conventional semiconductor refrigerating drinker: 1, adopt circular rod type and circle cup type cold heat exchanger (also claiming cold collector) usually, this heat exchange structure is unreasonable, and effective heat exchange area is little; 2, the assembling of cold heat exchanger and inner bag is unreasonable, and all is the interior middle or middle top position of inner bag of packing into from the side; 3, cooling fan is directly from back plate air port air intake or draw wind.Above defective causes the drinking water in the inner bag effectively to cool off volume reducing, and cold heat exchanger and water heat transfer rate are slow, and refrigerating efficiency is low, and poor refrigerating capability, speed are slow, so that can not be effectively the temperature of drinking water be reduced rapidly.During cooling fan work, noise is higher.

The purpose of this utility model provides that a kind of heat exchange structure is rational, effective heat exchange area is big, cold heat exchanger is reasonable with the inner bag assembling, the high efficiency semiconductor refrigeration water dispenser that the cooling fan operating noise is low.

This high efficiency semiconductor refrigeration water dispenser still has water feed apparatus, discharging device, holds water inner bag and heat-insulation layer thereof, the cold junction of its semiconductor cooler is close to cold collector, hot junction held against heat sink and cooling fan thereof, cold collector places inner bag, the utility model is characterised in that cold collector is fixed on inner bag level top, and cold collector places the part of inner bag to be the plate fin shape.

The utility model with said structure characteristics places plate fin formula cold collector the position of inner bag level top, cold junction is lowered the temperature rapidly after semiconductor cooler energising work, the plate fin effective heat exchange area of cold collector in inner bag is big, in case Jie Chu water temperature reduces its density increase and sinks fast with it, the uncooled liter waterborne of lower floor in the inner bag, make the water in the inner bag form quick convection current, reach finally that refrigerating speed is fast, efficient is high, refrigerating capacity is big and purpose of energy saving.

Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously.

Fig. 1 is the utility model embodiment partial structurtes cutaway views.

Wherein: 1, air channel, 2, blower fan, 3, radiator, 4, semiconductor cooler, 5, the frame pad, 6, plate behind the fuselage, 7, cold collector, 8, the courage shell, 9, heat-insulation layer, 10, inner bag.

As shown in the figure, these conventional equipments of Inlet and outlet water in the cooling-water machine have been omitted among the figure, in semiconductor cooler 4 both ends of the surface radiator 3 and cold collector 7 are set respectively, when leading to direct current for semiconductor cooler 4, can produce pal and paste effect, cold collector 7 these ends produce the heat absorption phenomenon, cold collector 7 generally is made up of the very big metal material of thermal conductivity factor, heat-absorbing action makes the water in cold collector 7 plate fin ends and the inner bag 10 carry out heat exchange and makes water temperature decline, the plate fin formula cold collector 7 of large tracts of land contact can effectively improve heat exchanger effectiveness, in addition, this cold collector 7 places inner bag 10 horizontal upper, make the rapid decline of water of cooling and carry out heat exchange completely without the water that cools off, reach fully effectively cooling comprehensively, wherein, cold collector 7 best its wide lower ends, plate fin upper end are narrow, and, can give full play to its heat exchange advantage completely rapidly perpendicular to horizontal plane.Radiator 3 these ends produce exothermic phenomenon, and quick heat radiating is diffusing in the fuselage outer air with the rapid row of heat by force through cooling fan 2, on the structure arrangement with the horizontally-arranged radiator 3 that in fuselage, faces of blower fan 2 levels, be provided with 1 shape chamber, air channel between the air intake barrier behind cooling fan 2 and the fuselage on the plate 6, so structure arrangement has solved the consistency problem on arrange blower fan 2 installation sites simultaneously with blower fan 2 and the wind seismic noise that plate inlet scoop, back spaces out and can reduce blower fan close neighbour air inlet in the routine and produce.
