Description

Semiconductor water cooled direct radiating regrigerator

The utility model relates to a kind of conductor refrigeration and the water-cooled refrigerator that directly dispels the heat.

Conventional refrigerator adopts the mechanical compress system with cooling fluid (fluorine Lyons) compression back decompression cooling by heat absorption, this refrigerator is the energy consumption height not only, and complex structure costs an arm and a leg, has noise, and cooling fluid is poisonous, volatile, leakage, and its direct prestige is being assisted human habitat.Therefore all replaced traditional mechanical compression type refrigerating plant with solid-state low-temperature receiver-semiconductor cooler both at home and abroad in recent years in research, its hot-side heat dissipation adopts the mode of the cold or forced air cooling of running water, but these types of cooling all exist the energy consumption waste excessive, deficiencies such as complex structure, radiating effect difference are unfavorable for applying.The radiating end that at present hot pipe technique is used in semiconductor cooler is the open description of the invention of CN85103275A, it is combined into the refrigerator cooling system with low temperature cassette gravity heat pipe and semiconductor cooler in the method handle of bonding, the formation bottom is a refrigerator, top is the modular appliance of water tank, and heat pipe is immersed in the hydrostatic and dispels the heat, it has certain superiority than running water cold-peace forced air cooling, but still there are deficiencies such as complex structure, and to fill in the heat pipe with liquid refrigerant, the heat in semiconductor hot junction will be passed to liquid refrigerant through the heat pipe lower bottom cover, by the gravity reflux of liquid refrigerant heat is passed to heat pipe radiating fin again, reached in the water by fin at last, this has just limited the effect of the reduction and the heat radiation of cost.

The purpose of the utility model is to overcome the deficiency of prior art existence, and a kind of semiconductor water cooling formula refrigerator of simple in structure, cheap, good heat dissipation effect is provided.

The utility model is achieved like this: it is combined by refrigerator, water heater, water tank, and refrigerator comprises shell, heat-barrier material, inner bag, refrigerating chamber; The refrigerator refrigeration makes the refrigerating chamber cooling by the heat of conductor refrigeration end through cool storage container absorption inner container of icebox; The cooling of refrigerator then is made of semiconductor cooler, water heater, water tank, put a heat-conducting plate that links to each other with water heater in the semiconductor cooler hot junction, water inlet and delivery port are respectively established in the water heater upper and lower, be provided with water inlet and hot water valve at water tank upper, the water tank bottom sets out the mouth of a river and cold valves, and power supply is located at water tank bottom for semiconductor cooler work.

The utility model compared with prior art has following advantage:

Because the principle that it adopts water-cooled directly to dispel the heat makes the heat in semiconductor hot junction directly pass in the water through heat-conducting plate, not only reduce cost, simplified structure, and utilize big these characteristics of specific heat of water, and make thermograde less, further improved radiating effect.The conductor refrigeration end directly to inner container of icebox (metal partly) heat absorption, had both made structure simpler through cool storage container, had increased the icehouse useful space again.Power supply adopt 12 volts (semiconductor cooler WCA-08-127 type, refrigerating capacity, 82 kilocalories/hour, volume 5.0 * 50 * 16mm ³, just can be swaged into volume with two is 60～80 liters refrigerator), be fit to the DC current of common car and boat, opened up the refrigerator new markets, be the desirable regeneration product of refrigerator.

Concrete structure of the present utility model is provided by the following example.

Fig. 1 is the side view of the utility model.

Fig. 2 is the longitudinal sectional drawing of the utility model;

Fig. 3 is the transverse cross-sectional view of the utility model;

As shown in the figure, water tank 1, filling heat-barrier material 16 edge setting-in panels 19 between water heater 2 and the outcase of refrigerator 17, filling with insulation material 16 between outcase of refrigerator 17 and the inner container of icebox 15, inner bag 15 is by two partly forming up and down, and top is heat-conducting metal, the bottom is a non-toxic plastic, have square hole at outcase of refrigerator below water tank, so that cool storage container 13 is installed, cool storage container 13 is fixed on the inner bag metallic walls by screw; Water heater 2 places water tank 1 middle part or position, water heater delivery port 6 can be connected with flexible pipe respectively with water outlet of water tank 4 with water tank inlet 7, water heater water inlet 5 on the lower side, water heater 2 can directly be fixed on the square hole place of outcase of refrigerator 17 with screw, semiconductor cooler 11 places therebetween, semiconductor cooler hot junction 10 directly contacts with water heater heat-conducting plate 9, semiconductor freezer cold end 12 contacts with cool storage container 13, and its contact-making surface scribbles heat-conducting silicone grease; Water tank 1 can be connected as a single entity by end seat and top cover with outcase of refrigerator.Power supply 18 is made up of transformer, rectifier, wave filter, and power supply can adopt 12 volts, and semiconductor cooler adopts the WCA-08-127 type, its refrigerating capacity be 82 kilocalories/hour, volume 50 * 50 * 16mm ³, just can make volume with two is 60～80 liters refrigerator, is suitable for the dc source of common car and boat, can open up the new markets of refrigerator greatly.

The course of work of the present utility model is: the refrigeration end 12 of semiconductor cooler 11 causes the refrigerating chamber cooling through the heat of cool storage container 13 absorption inner container of icebox 15.It heats end 10 by the heating of the water in 9 pairs of water heaters of heat-conducting plate, the raise heated liter waterborne in back and flow in the water tanks of water temperature through water heater top delivery port 6, water in water tank is from bottom delivery port 4, flow into through water tank inlet 5, water is heated rising again thereupon, so circulation can obtain 35 ℃～40 ℃ hot water, and reaches the purpose of cooling refrigerator.
