Problems solved by technology

But in some occasions, due to the limitations of processing technology, fuel combustion cannot play its role, such as portable electronic devices such as mobile phones and laptop computers. At present, people mainly rely on batteries to provide energy for them.
Due to the characteristics of small size and easy portability, chemical batteries have a lot of room for use in these occasions, but their disadvantages are also obvious, because of their low energy density and short continuous working time, they need to be replaced or charged frequently

Abstract

The invention relates to a micro-combustion thermal-photovoltaic generating device with a regeneration function and aims to provide an electrical power generating system taking a micro-combustor as a heat resource and capable of converting thermal radiation into electric energy. The generating device comprises a shell, a fuel bin, a fuel flow regulator, a mix chamber, igniters, parallel N micro-combustors, thermal photovoltaic panels and a composite two-way airway, wherein the fuel bin is arranged in the shell and used for storing fuel, and the fuel flow regulator is used for controlling flow of the gasified fuel. Compared with the prior art, the micro-combustion thermal-photovoltaic generating device has the advantages that energy density is large by taking liquefied gas as the fuel, and sustainable working time of a system is long; part of waste heat is recycled by the adoption of the composite two-way airway, and thermal efficiency and stability of the system are improved.

Description

Technical field: [0001] The invention belongs to the technical field of micro-scale power generation, and more specifically relates to a micro-combustion thermal photovoltaic power generation device with a heat recovery function. Background technique: [0002] Burning fuel to generate energy is the most widely used energy utilization method in production and life. 90% of the world's energy is used directly or indirectly through combustion. But in some occasions, due to the limitation of processing technology, fuel combustion cannot play its role, such as portable electronic devices such as mobile phones and notebook computers. At present, people mainly rely on batteries to provide energy for them. Due to its small size and easy portability, chemical batteries have a lot of room for use in these occasions, but their disadvantages are also obvious, because of their low energy density and short continuous working time, they need to be replaced or charged frequently. Therefore...
