High-efficiency direct-fired thermoelectric semiconductor power generator

Abstract

A high-efficiency direct-fired thermoelectric semiconductor power generator comprises a heat collector, a radiator and a thermoelectric module. The heat collector with a collector cover (4) and fins (12) is used for collecting heat, the radiator (8) with fins and a fan (7) is used for radiating heat, the thermoelectric module (9) is mounted above the heat collector (10), graphite paper is stuck on both a cold face and a hot face of the thermoelectric module (9), the hot face of the thermoelectric module (9) is attached to the heat collector (10) through the graphite paper, the cold face of the thermoelectric module (9) is attached to the radiator (8) through the graphite paper, the fan (7) is mounted outside the radiator (8), and the thermoelectric module (9) is connected with a socket (6) through a lead to deliver electric energy to the outside. The high-efficiency direct-fired thermoelectric semiconductor power generator is stable in provided voltage, simple in structure, long in service life, small in size and convenient to carry and economically affordable, and applied to places without power supply and being badly in need of electric power, such as outdoors, remote areas and emergency situations where electricity can be directly generated only by requiring fire sources for supplying heat.

Description

[0001] technical field [0002] The invention relates to the technical field of semiconductor thermoelectric power generation, in particular to a high-efficiency direct-fired thermoelectric semiconductor power generation device. Background technique [0003] Semiconductor small thermoelectric generators are widely used in outdoor, remote areas and emergency situations where there is no power supply and power is urgently needed due to its small size, easy portability, simple operation, and direct power generation with only a fire source providing heat. welcome. However, in order to save cost and be easy to carry, the thermoelectric modules used in existing semiconductor small-scale thermoelectric power generation devices are usually relatively small in size compared to the fire source. It is very difficult to collect heat, which leads to low efficiency of actual use of heat. The reduction of the actual heat of the thermoelectric module directly leads to a decrease in the...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the fact that the size of the thermoelectric module used in the semiconductor small-scale thermoelectric power generation device is small compared to the fire source, and the thermoelectric power generation device is directly placed in the Above the fire source, the scattered heat from the fire source is not easy to concentrate, which leads to unstable temperature of the hot surface of the thermoelectric module, low efficiency of heat utilization, and insufficient temperature difference between the cold and hot surfaces to affect power generation efficiency. A high-efficiency direct-fired thermoelectric power generation device is provided , can use the fire source as the heat source, use a special heat collector with a heat collecting cover and fins to provide efficient and stable heat, and use a radiator with a fan to ensure the temperature difference between the cold and hot surfaces of the device to increase output power and energy conversion efficiency
