Method and device for generating power by using temperature difference

Abstract

The invention provides a method and a device for generating power by using a temperature difference. The method for generating the power comprises the following steps of: utilizing a heat conductor, wherein the heat conductor is wrapped by a heat-insulation pipe and only two ends of the heat conductor can be contacted with an external environment; connecting an environment with a relatively low temperature with a part needing temperature reduction or a low temperature in a generator set, and connecting an environment with a relatively high temperature with a part needing heating or a high temperature in the generator set, so as to generate the power by the generator set. The device for generating the power is provided with a heat collector, a heat radiator, the generator set, the heat conductor and the heat-insulation pipe. The method and the device for generating the power by using the temperature difference, provided by the invention, have the advantage of providing sufficient, sustainable and clean electric energy.

Description

technical field [0001] The invention relates to a power generating device, in particular to a method and a device for generating electricity by using temperature difference. Background technique [0002] We need electricity that is plentiful, sustainable, clean and as convenient as possible. [0003] At present, most of the power generation devices are thermal power generation, hydropower generation and nuclear power generation devices, and there are also new power generation devices such as wind power generation, solar power generation, geothermal power generation and tidal power generation. But there are the following disadvantages respectively: [0004] 1. Thermal power generation requires a large amount of chemical fuels, and the chemical fuels on the earth have been increasingly depleted after hundreds of years of disorderly exploitation by human beings. Gases such as carbon dioxide that cause the greenhouse effect, and under current technical conditions, the efficien...

Problems solved by technology

[0004] 1. Thermal power generation requires a large amount of chemical fuels, and the chemical fuels on the earth have been increasingly depleted after hundreds of years of disorderly exploitation by human beings. Gases such as carbon dioxide that cause the greenhouse effect, and under current technical conditions, the efficiency of this power generation method is low, resulting in a large amount of energy waste

[0005] 2. Hydropower generation requires sufficient water sources, which are severely restricted by geographical and environmental factors. At the same time, the project is huge, with huge investment, long construction period, involving immigration and other government affairs and even national defense security issues, and the damming of rivers has a negative impact on the ecological environment. destroy

[0006] 3. Nuclear power generation has problems such as high technical threshold, high political threshold, high operating risk and high cost of waste disposal, and the efficiency of this power generation method is low, resulting in a large amount of energy waste

[0007] 4. Wind power generation, solar power generation, geothermal power generation and tidal power generation are seriously restricted by geographical and environmental factors, and at the same time are very unstable, and the current high cost is difficult to popularize
