[0006] 2. The heat storage tank in this device uses oil as the heat storage material, and its heat storage effect is not good
[0007] 3. The cold storage tank in the device is filled with cooling liquid. When in use, the liquid in the cold storage tank needs to be pumped by a pump and other power devices to realize the flow of the liquid and then dissipate heat, resulting in limited use conditions

Abstract

The invention discloses a day-night temperature difference power generation device based on solar energy. The phase change of a liquid in a heat pipe is utilized so as to achieve temperature difference of the two ends of the heat pipe, and current can be generated by a loop by using a power generation principle of a temperature difference power generation sheet. By the day-night temperature difference power generation device, the situation of leakage and poor heat storage effect caused by oil used as a heat storage material in the prior art is prevented, a heat dissipating method adopting by the invention is to provide a heat collecting device with fins, through increasing the area of contact between the heat collecting device and the outside, heat dissipation function is further achieved, heat is not dissipated by using a liquid flowing mode in the prior art, and the limit on application environment is reduced.

Description

technical field [0001] The invention relates to the field of power generation, in particular to a solar energy-based diurnal temperature difference power generation device. Background technique [0002] With the increasingly urgent demand for self-powered technology for low-power devices such as wireless sensor network (WSN), the method of collecting natural energy and converting it into electrical energy supply has been continuously explored and realized. [0003] Among them, solar energy in natural energy is ubiquitous and has a relatively high energy density, and the technology for utilizing solar energy in high-power applications is already very mature. The newly developed temperature difference power generation technology has relatively low energy density and power generation efficiency, but its structure and control are simple, no vibration and noise, small size, safety and pollution-free, so it is more common in low-power applications. . [0004] At present, in the ...
