Abstract

The utility model relates to a semi-conductor refrigerating drinking water apparatus. The cold end of the semi-conductor refrigerator is closed to a cold collector, the hot end is closed to a radiator, and the cold collector is arranged in an inner container. When the dc is switched on, the cold end of the semi-conductor refrigerator cools fast and transmits the cold amount to the inner container through the cold collector to low down the water temperature. The utility model has the advantages that the cold amount of the cold end of the semi-conductor refrigerator is intensively transmitted to the inner side of the drinking water through the cold collector, the cold amount is transferred quickly, the loss is small, and the refrigeration speed is quickened and the cooling effect is raised obviously. The arrangement of the thermal bridge blocking layer reduces the loss of the cold amount greatly. The utility model has the advantages of reasonable structure, small volume, light weight, no pollution, and low cost, and is in no need of refrigerant.

Description

A kind of conductor refrigeration water fountain

The utility model relates to a kind of water dispenser, but specifically is a kind of water fountain of refrigeration.

The existing water fountain majority that freezes is realized cooling with mechanical compression type, its water fountain volume is big and heavy, therefore there is the people to propose to realize the drinking-water refrigeration with cooling technique of semiconductor, water dispenser with the semiconductor cooler making, it is big to have solved volume, problems such as heaviness, but also there are certain problem in the transmission means of conventional semiconductor refrigeration end cold and the blocking-up method of heat bridge, so that can not be effectively the temperature of drinking water be reduced, and cost is higher.

The purpose of this utility model provides a kind of good refrigeration effect, and cost is low, and is in light weight, the conductor refrigeration water fountain that volume is little.

The purpose of this utility model is achieved in that the cold junction of semiconductor cooler is close to barred body formula cold collector, the hot junction held against heat sink, and cold collector places inner bag.After passing to direct current, the cold junction of semiconductor cooler is lowered the temperature rapidly and by cold collector cold is reached inner bag, realizes the cold exchange of cold collector and drinking water, and water temperature is descended, and the heat that is exchanged is emitted by blower fan by radiator.

The utility model has the advantages that the cold of semiconductor freezer cold end concentrated through cold collector to reach drinking water inside, cold shifts rapidly, and loss of refrigeration capacity is little, refrigeration rapidly and cooling-down effect obviously accelerate and raising; The setting of heat bridge barrier layer has reduced the loss of cold well; Rational in infrastructure, volume is little, and is in light weight, need not use refrigerant, and pollution-free, cost is low; It is the desirable water dispenser of family, office.

Below in conjunction with drawings and Examples structure of the present utility model is further described.

Fig. 1 is the utility model structure cutaway view.

By accompanying drawing as can be known, structure of the present utility model comprises cold collector (1), semiconductor cooler (2), barred body formula radiator (3), blower fan (5), insulation material (6), gasket material (7), wind-guiding road (8), shell (10), inner bag (9) etc., the refrigeration end of semiconductor cooler is close to barred body formula cold collector (1), radiator is provided with axial flow blower (5) and wind-guiding road (8), the galvanic couple that semiconductor cooler (2) is made up of P type and N-type semiconductor material is to being composed in series, when leading to direct current for semiconductor cooler (2), to produce the heat absorption phenomenon at the end face of being close to barred body formula cold collector (1), and can produce exothermic phenomenon at held against heat sink (3) end face, it is peltier effect, cold collector (1) is (as copper by the very big metal material of thermal conductivity factor, aluminium, stainless steel etc.) form, the cold of semiconductor cooler (2) cold junction carries out heat exchange by cold collector (1) and drinking water (4), water temperature is descended, the heat in semiconductor cooler (2) hot junction is discharged into heat in the air by radiator (3) and the axial flow blower (5) that is contained in semiconductor cooler (2) dead ahead, hot junction, for preventing to form turbulent flow because of air agitation, cause noise, be provided with wind-guiding road (8).Heat group circle is equipped with at the attachment screw two ends between cold collector (1) and radiator, does not promptly influence tight connection, reaches the purpose of blocking-up heat bridge again.For the loss that reduces semiconductor cooler (2) cold junction cold with accelerate transfer of heat between hot junction and the radiator (3); respectively have one deck thermal grease conduction and one deck elastomeric material at its contact-making surface; the effect of elastomeric material is that protection semiconductor cooler (2) is subjected to mechanical pressure and not impaired; and reduce the influence of extraneous thermal radiation and cross-ventilation to cooling effect; fill insulant material (6) and gasket material (7) between inner bag (9) and shell (10); for guaranteeing drinking water quality; at cold collector (1) surface-coated layer protective layer (four sulfone ethers; polytetrafluoroethylene (PTFE) etc.); inner bag (9) is made by food grade plastic; the refrigeration of this structure is compared with similar water dispenser; low 5-7 ℃ of drinking water temperature drop, cost is 70% of a similar type.
