Inflatable solar water heater heat insulation antifreezing gasbag

Abstract

The invention provides an inflatable solar water heater thermal insulation and antifreeze airbag, which includes a solar module installed on a solar installation frame, an L-shaped installation frame is installed on the upper and lower sides of the solar energy installation frame, and the upper and lower two L-shaped installation frames are respectively installed. There is an air suction pump and an air intake pump, the air intake of the air extraction pump is connected to the air bag through the air extraction pipe, the air outlet of the air intake pump is connected to the air bag through the air intake pipe, a mounting part is installed on the solar module header via bolts, the An airbag is installed on the mounting part, and a guide plate inclined from right to left is installed on the solar energy mounting frame. The present invention uses an air intake pump to fill high-pressure gas into the telescopic air pipe to make the telescopic air pipe stretch and prevent heat loss in the vacuum pipe. Or when the temperature is low on cloudy days, the pipeline will be cracked or blocked by freezing. It has high safety. The use of pearl cotton insulation material has excellent thermal insulation effect, light weight and low cost, and can maintain the temperature of the vacuum tube for a long time.

Description

technical field [0001] The invention belongs to the technical field of solar water heaters, and in particular relates to an inflatable solar water heater thermal insulation and antifreeze air bag. Background technique [0002] A solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters. Vacuum tube solar water heaters occupy 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. Using the principle of hot water floating and cold water sinking, the water produces microcirculation to achieve the required hot water. [0003] In the cold winter nights in the north of our country, the temperature is low. The water in the solar water heater will freeze because the t...
