Abstract

The invention discloses a mold for hot bending and forming trough type solar concentrating collector parabolic mirrors and a manufacturing method thereof. The mold comprises a plurality of support plates and a support plate fixing device, wherein the plurality of support plates form a trough-shaped space fixing structure through the support plate fixing device; the support plates are sunk part structures obtained by cutting a whole steel plate according to a parabolic mirror molded line; a plurality of open slots are formed in cutting end faces of molded line sides of the support plates; corresponding formed steel pipes are arranged in the open slots corresponding to the adjacent support plates; the formed steel pipes are fixedly arranged tangent to end openings of the open slots through a steel pipe fixing device. The mold is simple in structure, reasonable in design and simple to manufacture, and is capable of effectively reducing production energy consumption and efficiently hot bending and forming glass of trough type parabolic mirrors.

Description

technical field [0001] The invention relates to a device for a trough-type solar concentrator, in particular to a molding die for a parabolic mirror of a trough-type solar concentrator, and belongs to the technical field of energy utilization. Background technique [0002] As a clean, non-polluting renewable energy source, solar energy is considered an important part of the world's energy strategy for its development and utilization. Solar thermal utilization is the most important way in solar energy utilization. The trough-type solar thermal utilization system mainly uses the trough-type parabolic concentrator to concentrate the sunlight emission on the heat-collecting tube, and uses the medium in the tube to export the heat energy for utilization. It has a relatively high efficiency. High, large scale, easy to standardize and so on. [0003] Solar thermal power generation is a method to replace conventional energy sources, and it is one of the focuses of scientists and go...
