Description

The new type solar energy refrigerator

Technical field

The utility model relates to refrigerator, relates in particular to a kind of new type solar energy refrigerator.

Background technology

Refrigerator is a kind of refrigerating plant, is used for the food fresh keeping storage, brings convenience to people's lives.Solar energy thermoelectric cooling technology is by the opto-electronic conversion effect sunshine to be transformed into electric energy, and output DC stream is for the work of thermoelectric cooling device.The solar energy refrigerator has the advantage of saving conventional energy resource protection atmospheric environment.Existing solar energy refrigerator, refrigeration is undesirable, and job stability remains to be improved, and poor mobility is difficult to carry.

Summary of the invention

The purpose of this utility model is to solve existing disadvantages of background technology, and the solar energy refrigerator of a kind of good refrigeration effect, stable working state is provided.

For achieving the above object, the utility model adopts following technical proposals: the utility model comprises the solar energy photovoltaic direct current power-supply system, thermoelectric cooling system, hot-side heat dissipation system.The solar energy photovoltaic direct current power-supply system is by solar panel (13), controller (12), and battery (14) is formed.The solar energy photovoltaic direct current power-supply system becomes electric energy to offer the thermoelectric cooling system with galvanic form transform light energy, simultaneously battery (14) is charged.Battery is the dc source of thermoelectric cooling system when sunlight is not enough, establish rectification module in the controller and connect alternating current, provide dc source to charge in batteries and for the thermoelectric cooling system, controller (12) is controlled solar energy refrigerator thermoelectric cooling system simultaneously, the running of water pump (11) and blower fan (8).

The thermoelectric cooling system is by semiconductor thermoelectric module (5), water-cooling type radiator (15), and cold junction radiator (4), air-cooler (1), battery (14) is formed.The cold junction of thermoelectric cooling system is arranged in the refrigerator, promptly produce Peltier effect behind semiconductor thermoelectric module (5) input dc power, cold junction heat absorption at semiconductor thermoelectric module (5) produces refrigeration, by cold junction radiator (4), the forced convertion of air-cooler (1) makes refrigerator inner chamber (3) refrigeration cool-down, the hot junction of semiconductor thermoelectric module (5) emits heat, become hot water after the water at low temperature heat absorption in the water-cooling type radiator (15), water circulating pump (11) is delivered to phase-change heat-exchanger (6) with hot water, the critical piece of phase-change heat-exchanger (6) is a thermal siphon, thermal siphon is by evaporator section (10), adiabatic section (9), condensation segment compositions such as (7).Liquid working substance at evaporator section (10) becomes gas because of the heat absorption carburation by evaporation, and (9) flow to condensation segment (7) to Working medium gas through the adiabatic section, sends heat the air of flows outside to, and blower fan (8) strengthens air and flows.In evaporator section (7), hot water flows outside the thermal siphon pipe, lower the temperature because of heat is absorbed by intraductal working medium, the low-temperature cooling water after the cooling is got back to and is absorbed the heat that the hot junction produces in the semiconductor thermoelectric module (5) in the water-cooling type radiator (15), thereby makes cold junction absorption refrigeration continuously, by cold junction radiator (4), air-cooler (1), refrigerator inner chamber (3) temperature reduces, under the situation of 32 ℃ of environment temperatures, can make its temperature maintenance about 5～10 ℃, reach the temperature effect that the springhouse needs.

The hot-side heat dissipation system is by water-cooling type radiator (15), water pump (11), and phase-change heat-exchanger (6), the chilled(cooling) water return (CWR) is formed.Semiconductor thermoelectric module in the thermoelectric cooling system (5) hot junction is arranged on refrigerator rear wall outside, when direct current passes through semiconductor thermoelectric module (5), the heat that cold junction absorbs will be delivered to the hot junction, heat up in the hot junction, shift heat by water-cooling type radiator (15), guarantee the not too high security of system that influences of Yin Wendu of hot junction, keep cold junction and constantly absorb heat.Semiconductor thermoelectric module (5) cold junction end face places in the refrigerator inner chamber (3), and the hot junction end face places the refrigerator outside, and water-cooling type radiator (15) places the refrigerator outside, and refrigerator inner chamber (3) is provided with thermal insulation layer (2) with the outer interlayer of refrigerator, in order to avoid loss of refrigeration capacity in the cabinet.

The beneficial effects of the utility model are, solar panel (13) can be placed in the sunlight face flexibly, links to each other with refrigerator battery (14) by the lead plug connector, and rectification module links to each other with external ac power source by plug connector, make the utility model adapt to changeable weather environment, mobility increases greatly.The hot-side heat dissipation system adopts phase-change heat-exchanger (6), and thermal siphon improves thermoelectric cooling system works stability, and refrigeration is better.The utility model volume is little in light weight, is easy to carry.
