Abstract

The invention relates to a portable power supply device based on micro-combustion. The device comprises preheating channels 1 and 2, a mixed chamber 3, a micro-combustor 4 and a thermal photovoltaic power generation module 5 and further comprises a temperature difference power generation module 6, wherein combustion exhaust gas discharged from the micro-combustor 4 impacts the lower end face of the temperature difference power generation module. Compared with the prior art, the device provided by the invention has the advantages that the device combines the advantages of heat energy utilization modes of thermal photovoltaic power generation and temperature difference power generation, and the utilization efficiency of energy resources is greatly improved.

Description

Technical field: [0001] The invention discloses a high-efficiency portable power supply device based on micro-scale combustion. The device uses a micro-combustor as a heat source for thermal photovoltaic power generation and thermoelectric power generation, and performs cascaded utilization of heat energy, thereby realizing the maximization of thermal-electric conversion power . Background technique: [0002] Almost 90% of the energy in human social life comes from fossil fuel combustion. In recent decades, micro-devices and their systems such as sensors, micro-scale aircraft, regulators, micro-medical devices, micro-pumps, micro-motors, etc. have been used in national defense, scientific research, It is widely used in medical and industrial fields. The above-mentioned devices, systems and products all require the energy supply system to have the characteristics of small size, light weight, high energy density and long duration. Basic primary alkaline batteries, rechargeab...
