[0002] The existing solar heat collection strip is a vacuum flat heat collection strip. This kind of heat collection strip usually uses a vacuum heat pipe to be placed in a double-layer vacuum glass interlayer, and the vacuum heat pipe is placed on the condensation end outside the glass plate. Release heat to heat the cold water, and then heat the water in the solar water tank through the thermal cycle between the upper circulation pipe and the lower circulation pipe. This kind of solar vacuum flat heat collection strip is difficult in the manufacturing process due to the vacuum production process. The production cost is high, and the sealing is difficult to guarantee for a long time; in terms of sealing, sealing strips are used around the heat collecting strips, and the process is more complicated
[0003] The disadvantage of this structure is that both the front panel and the back panel are made of tempered glass, and the middle is a vacuum, which makes the vacuum process and sealing structure more difficult and the cost is too high

Technical field: [0001] The invention belongs to the technical field of solar heat collection strip structure. Background technique: [0002] The existing solar heat collection strip is a vacuum flat heat collection strip. This kind of heat collection strip usually uses a vacuum heat pipe to be placed in a double-layer vacuum glass interlayer, and the vacuum heat pipe is placed on the condensation end outside the glass plate. Release heat to heat the cold water, and then heat the water in the solar water tank through the thermal cycle between the upper circulation pipe and the lower circulation pipe. This kind of solar vacuum flat heat collection strip is difficult in the manufacturing process due to the vacuum production process. The production cost is high, and the sealing is difficult to guarantee for a long time; in terms of sealing, sealing strips are used to surround and seal around the heat collecting strip, and the process is relatively complicated. [0003] The dis...
