Novel solar heat exchange pipe assembly structure

Abstract

The invention discloses a novel solar heat exchange pipe assembly structure. The novel solar heat exchange pipe assembly structure comprises a heat exchange pipe body, semi-circular concave plates, first fixed rods, a bearing, a rotary rod, a strip-shaped through groove, a first sealing ring, a U-shaped rod, a heat exchange water tank, a vacuum pipe insertion opening, second fixed rods, a fastening screw nut, a sealing cover, a second sealing ring, an assembly hole, a joint block and brushing blocks. The novel solar heat exchange pipe assembly structure is reasonable in design; assembly connection firmness is improved; the phenomenon that most part of the heat exchange pipe body is suspended in the heat exchange water tank is avoided; the bearing capacity of the heat exchange pipe for water in the pipe is improved; water scale cleaning on annular surfaces of the heat exchange pipe is facilitated; heat transferring efficiency is ensured; and the hole diameter of each spiral structure ofthe heat exchange pipe body is smaller than the distance between larges concave surfaces of two corresponding semi-circular concave plates at staggered positions, so that the annular surfaces of theheat exchange pipe body favorably cling to the semi-circular concave plates, and water scales on the outer surfaces of the heat exchange pipe body are favorably brushed by the brushing blocks.

Description

technical field [0001] The invention relates to a heat exchange tube installation structure, in particular to a novel solar heat exchange tube installation structure, which belongs to the technical field of solar energy applications. Background technique [0002] The heat exchange tube is one of the elements of the heat exchanger. It is placed in the cylinder and used for heat exchange between two media. It has high thermal conductivity and good isothermal performance. One point to another device, and there is almost no heat loss, so it is called a heat transfer superconductor, its thermal conductivity is thousands of times that of copper, and it is most common in the application of hot and cold water delivery in solar water heaters. [0003] The heat exchange tubes of the widely used solar water heaters are placed in the water tank, and the heat exchange tubes are installed in the water tank with less support and fixed parts, so that the heat exchange tubes are empty in the...

AI Technical Summary

Problems solved by technology

[0003] The heat exchange tubes of the widely used solar water heaters are placed in the water tank, and the heat exchange tubes are installed in the water tank with less support and fixed parts, so that the heat exchange tubes are empty in the water tank, resulting in weakened water bearing capacity of the heat exchange tubes. Long-term immersion in the liquid of the water tank will cause scale on the surface of the heat exchange tube, which is inconvenient to clean. As the thickness of the scale increases, the heat transfer efficiency will decrease
