Abstract

The invention relates to a thermoelectric power generation device, in particular to a thermoelectric power generation system based on methanol in-situ catalytic combustion, and belongs to the technical field of energy. Methanol is adopted as fuel, so that the energy density of the system can be effectively improved; catalytic combustion is adopted as a heat source, a high-quality and stable heat source can be provided, and compared with traditional flame combustion, combustion is more mild, and the cruising ability of the system can be effectively improved; a thermoelectric device is adopted as an energy conversion device, the device can be suitable for various use environments, especially low-temperature environments, and the lower the temperature is, the better the cooling effect of the cold end is, and the better the output performance of the device is; and the catalytic heat source and the thermoelectric device are integrated, so that the thermal resistance between the heat source and the thermoelectric device can be reduced, and the heat conduction capability of the hot end is improved.

Description

technical field [0001] The invention relates to a thermoelectric power generation device, in particular to a thermoelectric power generation system based on in-situ catalytic combustion of methanol, belonging to the technical field of energy. Background technique [0002] With the development of the Internet of Things and the deployment of distributed sensors, the demand for portable power supplies is increasing. Battery technology is expected to meet part of the demand, but the energy and power characteristics of batteries are seriously attenuated in low-temperature environments. Therefore, it is necessary to propose a portable power supply that can operate in low-temperature environments and have long battery life. Another way is to use high-energy-density hydrocarbon fuel as an energy source, and use an energy conversion device to release electrical energy. For example, a fuel cell directly converts the chemical energy of the fuel into electrical energy through an electro...
