Abstract
An eco-friendly linear solar heat generating system may employ a linear engine with a simple structure using solar heat is employed in place of a conventional Stirling engine with a complicated structure. Magnets and a coil are arranged in a piston and a cylinder, respectively, to thereby generate power in a highly efficient matter, improve installation stability, and enable easy maintenance and repair.
Claims12
A linear solar heat generating system, comprising:
- a frame;
- a solar concentrator installed in the frame and configured to concentrate the sunlight;
- a heat engine constituted with a cylinder and high-pressure gas, the cylinder divided into a front space and a rear space by a piston, the high-pressure gas housed in the front space and the rear space of the cylinder, the piston being linearly reciprocated by thermally expanding or contracting the high-pressure gas housed in the front space and the rear space of the cylinder by alternately transferring the concentrated sunlight from the solar concentrator to the high-pressure gas;
- and
- a power-generating unit constituted with a plurality of magnets and a coil, the plurality of magnets installed lengthwise along an outer circumference of the piston, the coil wound lengthwise along an outer circumference of the cylinder, the magnets oscillating according to a linear reciprocating motion of the piston to generate electricity from the coil.
