Abstract
The invention discloses a kind of heat-insulated hoods of solar vacuum heat-collecting pipe high temperature resistant high reflection for belonging to solar energy heat utilization technical field.The present invention is fixed on by metal fastenings on thermal-collecting tube, including：Ceramic matrix, heat-insulated internal layer and high reflection outer layer, heat-insulated internal layer are attached on the inside of ceramic bases, and high reflection outer layer is attached on the outside of ceramic bases.Oxidation reflected sunlight simultaneously can not occur in the case where height is focused on and irradiated than sunlight for this hood, while can completely cut off again since the heat that high focusing sunlight long-term irradiation accumulates has the function that protect heat-collecting tube sealing position and bellows.It increases in the high reliability and service life focused on than thermal-collecting tube under use condition.
Description
Technical field
The invention belongs to solar energy heat utilization technical fields, and in particular to a kind of solar vacuum heat-collecting pipe high temperature resistant
The heat-insulated hood of high reflection.
Background technology
With the rapid development of science and technology, demand of the people to the energy increasingly increases.Solar groove type heat power generation into
Hot spot of concern.High temperature solar evacuated collector tube is the core component in groove type solar power station, has obtained the wide of people
General research.To obtain higher system effectiveness, condenser system focuses on ratio and is increasing, and under the conditions of height focuses on ratio, tradition
Aluminum or stainless steel hood will occur to aoxidize in use and then lose interception, while hot caused by optically focused
Amount will be conducted to heat-collecting tube sealing position and bellows, so as to cause the breakage of bellows.
Invention content
The present invention provides a kind of solar vacuum heat-collecting pipe high temperature resistant to overcome shortcoming in the prior art
