AI Technical Summary

Technical Problem

When existing biaxial trough solar collectors are operating at an angle, the internal liquid working fluid is easily affected by gravity and tends to accumulate at lower levels, resulting in uneven liquid distribution on the heated surface, reducing heat exchange efficiency. Furthermore, the steam experiences high flow resistance and slow discharge speed during transport, affecting the stability of the system's heat transfer.

Method used

Inside the solar collector, a distribution component and a steam guiding mechanism are installed. The distribution component uses equally spaced partition mesh to block the flow of evaporating liquid in sections. The honeycomb sleeve absorbs the evaporating liquid and maintains its distribution. The steam guiding mechanism accelerates steam delivery through small pipe openings and high flow rates, and optimizes steam discharge using fluid dynamics principles.

Benefits of technology

It effectively solves the problem of uneven liquid distribution, improves heat exchange efficiency, and ensures the high efficiency and stability of energy transmission by accelerating steam transport and preventing condensation.

Abstract

This invention discloses a biaxial trough solar collector and its usage method, relating to the field of solar energy technology. The invention includes a solar collector, a biaxial support, an energy distribution mechanism, a heat collection mechanism, and a steam guiding mechanism. The invention incorporates a distribution component within the heat collection mechanism. Equally spaced partition meshes divide the inner cavity of the inner heat collection tube into multiple independent areas, segmentally blocking the free flow of the evaporating liquid. Combined with a water outlet trough on the bottom water pipe for continuous leakage, the evaporating liquid is absorbed by the honeycomb sleeve and held in a specific position, exhibiting a "quasi-solid" distribution. This design effectively overcomes the problem of uneven distribution caused by gravity-induced liquid accumulation at lower elevations when the collector tilts due to angle adjustments of the biaxial support, ensuring uniform heat exchange efficiency of the heat collection tube at different angles.
