Hot water temperature differential power generation device

Abstract

The invention discloses a hot water temperature differential power generation device which comprises a heat collector, a first storage tank, a second storage tank, a plurality of silicon semiconductors, a plurality of germanium semiconductors, a plurality of metal conductors, two power supply leading wires, a cold water cooling panel and a low-power-consumption circulating water pump. The first storage tank is used for storing hot water for heating hot ends of semiconductor power generation elements. The second storage tank is used for storing cold water for cooling cold ends of the semiconductor power generation elements. The plurality of silicon semiconductors and the plurality of germanium semiconductors are arranged in parallel in a mutually alternately mode. The plurality of metal conductors are used for connecting the tail ends of the silicon semiconductors and the tail ends of the germanium semiconductors in series. The two power supply leading wires are respectively led out from the metal conductor fixed at the leftmost end among the cold ends and the metal conductor fixed at the rightmost end among the cold ends. The cold water cooling panel is used for rapidly scattering excessive heat conducted from the hot ends into the cold water so as to ensure that the temperature difference between the hot ends and the cold ends can be stabilized at a specified value. The low-power-consumption circulating water pump is used for pumping underground water through a sealed pipeline to be the cold water. The hot water temperature differential power generation device is simple in structure, low in invested cost, convenient to install, environment-friendly and energy-saving, and solves the problems that inhabitants in an area without electricity need to use electricity or the inhabitants are badly in need of electricity when power failure happens.

Description

technical field [0001] The invention relates to a power generation device, in particular to a hot water temperature difference power generation device. Background technique [0002] In nature, temperature difference is everywhere, from seasonal temperature difference, day and night temperature difference, temperature difference between the surface and under the ground, etc. These temperature differences contain huge energy and need to be developed and utilized. At present, there are still many places in China that lack or even have no electricity supply for a long time. The difficulty of using electricity in these areas without electricity has become a difficult problem that needs to be solved urgently. However, the cost of erecting generator sets is too high for low-density population areas to be realized. status quo. Moreover, traditional natural thermal power generation methods use heat engines, generators or steam turbines as prime movers. Such systems can only obtain g...
