Solar thawing disk based on peltier effect

Abstract

The invention discloses a solar thawing disk based on peltier effect. Photovoltaic cell panels are utilized to generate electricity, also electric energy is stored in a storage battery, when thawing is needed, a switch is turned on and the storage battery is utilized to drive thermoelectric batteries, the peltier effect of the thermoelectric batteries can generate a lot of heat, and the heat is transferred to thawed food for thawing. The energy of the solar thawing disk provided by the invention comes from the electricity generated by the photovoltaic cells with solar energy, therefore the solar thawing disk provided by the invention has no need for additional energy input; and secondly, the heat absorbed by the frozen food in the invention partly comes from the electric energy supplied bythe storage battery to the thermoelectric batteries, and the other part comes from the environmental heat absorbed by the peltier effect of the thermoelectric batteries, and the part of energy is dozens of times that provided by the storage battery. Therefore, the device provided by the invention has the advantages of green and environmental protection, energy saving and high efficiency.

Description

technical field [0001] The invention relates to food thawing technology, in particular to a solar thawing plate based on the Peltier effect. Background technique [0002] With the popularization of refrigerated food in household refrigerators, the storage time of food is extended by freezing, but at the same time, how to thaw food quickly when it is used has become a major problem in life. At present, the traditional thawing methods mainly include air thawing, water thawing, and microwave thawing. These three traditional thawing methods respectively have the disadvantages of slow thawing speed, waste of water resources, and high energy consumption. If a thawing device capable of autonomous power supply and heating can be designed, there is no need to waste precious water resources, and no additional power input is required, and at the same time, a good thawing effect can be achieved. [0003] Solar energy is an inexhaustible and inexhaustible source of clean energy. Using ...
