Integrally packaged type solar heat collector with combined curved surface for light collection and vacuum tube for heat collection

Abstract

The invention discloses an integrally packaged type solar heat collector with combined curved surface for light collection and vacuum tube for heat collection, belonging to the technical fields of solar light collection and medium and high temperature solar heat collection. The solar heat collector of the invention comprises a combined curved surface light collector, a vacuum tube heat collector, an adjustable tracker, a packaging shell and the like. After the sun light enters the combined curved surface light collector through a transparent glass cover plate, the sun light is reflected through an inner surface of the combined curved surface light collector and collected onto the vacuum tube heat collector, the vacuum tube heat collector absorbs the sun light to generate high-temperature heat energy, and the heat energy is conducted and transmitted to users by a heat conducting working medium in the vacuum tube heat collector. The invention can collect the sun light with low energy flow density after being reflected by a plurality of curved surfaces on the vacuum tube heat collector, thus the heat conducting working medium in the vacuum tube can be quickly heated to form high-temperature heat energy. The manually adjusted tracker can adjust the orientation of the combined curved surface light collector to track the sun, thereby enabling the heat collector to keep in the optimal sun light collecting state. The invention is especially suitable for use in high-latitude areas and in winter when the solar altitude is smaller.

Description

Technical field

[0001] The invention belongs to the technical field of solar energy concentration and solar high temperature heat utilization. Specifically, it is a new structure that uses a specially designed concentrator and a vacuum tube collector to form a new structure, and this new structure is packaged as a whole to make it a standard solar collector component, so as to realize the sunlight A solar energy utilization device that gathers high-density and generates high-temperature heat energy. Background technique

[0002] Among the medium and high temperature solar collectors currently popularized and used, there are mainly two types: rotating parabolic reflective point focus and two-dimensional parabolic trough reflective line focus (also known as trough concentrator). The advantage of the former is that the heat collecting temperature is high, and the disadvantage is that the scale of the device is limited and the process is complicated. The advantage of the latte...
