Abstract

The invention discloses a small free piston type solar generator system. The small free piston type solar generator system comprises a free piston type solar engine part and a permanent magnet linear generator part. The free piston type solar engine part comprises a heat exchanger and a power transmission device. The heat exchanger comprises a high-temperature-end heater, a regenerator and a cooler. The power transmission device comprises a distribution piston in an air cylinder and a power piston outputting mechanical energy. Heat energy of gas media is increased through the heater. The gas media flow circularly in the sealed air cylinder, the power device is driven to reciprocate, and heat energy can be converted into mechanical energy. The permanent magnet linear generator part comprises a permanent magnet motor rotor and a motor winding stator. The power piston in linear reciprocating motion is connected with the permanent magnet motor rotor. The stator in linear reciprocating motion enables inner magnetic flux in the winding stator to change, and mechanical energy can be converted into electric energy. The small free piston type solar generator system can be used for power generation devices with a solar heat source and other concentrated heat sources.

Description

Technical field: [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a small free-piston solar generator system, which is suitable for solar heat sources and other power generating devices with concentrated heat sources. Background technique: [0002] With the gradual depletion of energy sources such as oil and coal, human beings on the earth are facing a serious energy crisis.
