Problems solved by technology

The traditional vacuum tube solar water heater has the following disadvantages: 1. The water tank is large and suitable for installation on the roof, which does not meet the needs of high-rise buildings; 2. The glass vacuum tube is fragile and not pressure-resistant; 3. It cannot be used as a building material and The perfect combination of building integration
With the popularity of high-rise buildings, traditional vacuum tube solar water heaters can no longer meet the needs of high-rise buildings, while flat-panel water heaters can just meet the needs of high-rise buildings
In recent years, flat-panel water heaters have been widely used in high-rise buildings, but ordinary flat-panel water heaters have a slow heat collection rate and low heat transfer efficiency.

Abstract

The invention relates to a dual-vacuum tube flat-plate solar collecting module, comprising a frame, a heat exchanger, a glass cover-plate, an insulation layer, heat collecting tubes and a rear plate. The frame comprises two sides and a bottom, and the tops of the sides are connected with the heat exchanger to form a rectangular frame. The rear plate is disposed below the frame, and the frame and the rear plate enclose to form a rectangular box. The inner surface of the rectangular box is provided with the 10 to 20mm integrated high-density polyurethane foaming insulation layer, the rectangular box is further provided with the multiple heat collecting tubes connected with the heat exchanger, and the glass cover-plate is disposed above the heat collecting tubes. The heat collecting tubes which are fully enclosed heat-pipe vacuum tubes are formed by transparent glass outer tubes and coated glass inner tubes, or by the transparent glass outer tubes and coated metal inner tubes, and the top of each heat collecting tube is provided with a 15 to 20cm condensation section.

Description

Technical field: [0001] The invention relates to a double-vacuum-tube flat solar heat collecting module, which belongs to the technical field of solar water heaters. Background technique: [0002] A solar water heater is a device that converts sunlight energy into heat energy, and heats water from a low temperature to a high temperature to meet the needs of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. The traditional vacuum tube solar water heater has the following disadvantages: 1. The water tank is large and suitable for installation on the roof, which does not meet the needs of high-rise buildings; 2. The glass vacuum tube is fragile and not pressure-resistant; 3. It cannot be used as a building material and The perfect combination of architectural integration. With the popularity of high-rise buildings, traditional vacuum tube solar wate...
