Abstract
The invention relates to a low-temperature efficient stirling power generation device, which belongs to a temperature difference power generation device. The low-temperature efficient stirling power generation device comprises a gas distribution piston cylinder (1), a gas-guide tube (2), a power piston cylinder (3), a cylinder trough (4), a gas distribution piston cavity cover (5), a rubber ring (6), a large gas distribution piston (8), a power generator (15) and an energy storage capacitor (16). The gas in a cavity is heated, so that a gas distribution piston does a reciprocating motion up and down; due to the pressure variation, a power piston does a horizontal reciprocating motion in the power piston cylinder so that a flywheel is driven to rotate through a rocking bar; meanwhile, a driving wheel fixedly connected with the flywheel through a rotating shaft does a synchronous motion and drives a driven wheel to rotate through a transmission belt, so the generator generates power, stores the electric energy into the capacitor and outputs the electric energy. The stirling power generation device can generate power at low temperature efficiently and accord with the idea of saving energy and reducing emission; moreover, the energy storage capacitor is arranged in the device, so a very small current can be collected, the utilization rate of the energy by the conventional device is increased, and the integration degree is high.
