Description

technical field [0001] The invention belongs to the field of power generation device research, and in particular relates to a novel solar liquid heat thermoelectric power generation device. Background technique [0002] At present, the research on thermoelectric power generation in China is mainly based on the research of semiconductor materials, and the research on application is less, and the popularity of semiconductor thermoelectric power generation in civilian applications is still insufficient. According to current technology, after a few hours in summer, the water temperature of domestic solar water heaters can reach 90 degrees, reaching a saturated state, and the excess solar energy is not fully utilized, and the unutilized solar energy is still very abundant. Therefore, based on the existing principle of thermoelectric power generation technology and the principle of solar water heaters, the technical solution of this patent is to design a new type of solar liquid h...

Problems solved by technology

[0003] At present, there have been patent achievements of using solar hot water temperature difference to generate electricity. For example, in a solar thermoelectric power generation water heater CN 20323346 U, it uses the temperature difference between the solar collector and the vacuum heating tube to generate electricity. Small, after reaching the saturation state, the device will stop generating electricity, and the effect of making full use of excess solar energy has not been achieved.

In patents such as the solar liquid thermal thermoelectric power generation device CN 204733097 U, it uses the temperature difference between solar hot water and cold liquid to generate electricity, but the cold liquid and hot liquid circulation of this set of equipment needs to be driven by pumps, which wastes energy

Such as solar thermal power generation system CN103259458 A, this system is more complicated, the cost is higher, it is suitable for rivers, lakes and other places, not suitable for household
