Flat-plate solar heat collector production method

Abstract

Disclosed is a flat-plate solar heat collector production method. Firstly, production materials are well prepared according to the set sizes, specifically, a back plate is subjected to one-time punch forming, a thermal insulating layer is subjected to one-time high-pressure foam forming through polyurethane, a heat collecting layer is formed by laser welding through copper pipe flow and heat collecting film copper pipes, and edge covering is performed on joints of toughened glass and the back plate through rubber; and assembling is performed, specifically, the back plate, the thermal insulating layer, the heat collecting layer and the toughened glass are overlaid in sequence from bottom to top, and then the back plate and the toughened glass are locked through one-time punching by means of edge strip buckles. By means of the flat-plate solar heat collector production method, the product heat collecting effect and thermal insulating effect are greatly improved; the potential safety hazards due to multi-time connection in the product using process are reduced; the security coefficient is greatly improved; and the edge strip buckles are used for punching and locking, and therefore a flat-plate solar heat collector produced through the method is firm and easy to install.

Description

Technical field: [0001] The invention relates to the technical field of water heaters, in particular to a production method of a flat solar heat collector. Background technique: [0002] Solar water heaters are popular all over the world as clean energy and low-cost water heaters, and flat-panel solar energy is currently the most popular one, but the flat-panel solar collectors currently used are basically split, and their aluminum alloy frames It is connected by corner codes, and then assembled and pressed into frames. Due to design defects, it is difficult to fully seal due to the large number of joints during use, and after long-term wind and daily exposure, it is easy to produce gaps in the joints, which affects the set. The overall sealability of the heater and its heat collection effect, and secondly, due to the large number of connections, it is easy to cause local connections to be loose and there is a risk of disintegration and falling off, causing potential harm to...
