Abstract

The invention relates to a pressure type solar water heater heat-collecting plate which is mode of aluminum and copper. The heat-collecting plate comprises an aluminum belt, an embedded pipe and a branch copper pipe penetrating through the embedded pipe. The production technological process comprises the following steps: processing the flexible embedded pipe by aligning, prepressing, removing entire oxide film and dedusting, inserting the obtained embedded pipe between two aluminum belts which are processed by removing oxide film and dedusting, then using a pressure bearing to press the aluminum belts and the prepressed embedded pipe together, utilizing a mould to press the pressed aluminum belt and obtain a stiffener, then rolling, performing electrolytic oxidation for coloring, blowing under high pressure, performing stage cutting and other procedures to obtain a semi-finished product, wherein the technological process is characterized in that the semi-hard or hard branch copper pipe penetrates through the embedded pipe of the semi-finished product prepared by the above procedures and the two exposed ends of the branch copper pipe are 20+ / -3mm; then using a roller to perform gap-closing to ensure that the flexible aluminum belts and embedded pipe stick to the surface of the hard branch copper pipe, finally welding and assembling, and performing pressure test.

Description

technical field [0001] The invention belongs to the field of heat generation and utilization, and in particular relates to the structure and production process of a pressure-bearing solar water heater heat collecting plate. Background technique [0002] Flat-panel solar water heaters widely use aluminum sheets and copper tubes as heat collectors. The traditional heat collectors sandwich a copper tube between two layers of aluminum sheets and flatten them to make the copper and aluminum tightly bonded. After surface coating Pre-flattened copper tubes are blown into shape using high-pressure water or compressed air. However, the traditional heat collector only has two layers of pressure-bearing materials, aluminum sheets and copper tubes, and the copper tubes are rolled and inflated, and the bending parts will be damaged to a certain extent. The pressure-bearing limit is low, and it is suitable for low water supply pressure. site, the scrap rate in the production process is h...
