Novel solar heat collector

Abstract

A novel solar heat collector comprises a plurality of vacuum glass heat collecting tubes, a support, a water feeding main tube and a water draining main tube, wherein lower ends of the vacuum glass heat collecting tubes are closed; the vacuum glass heat collecting tubes are fixed by the support; the water feeding main tube is connected with low-temperature water; the water draining main tube is connected with a heat-insulation water tank; the vacuum glass heat collecting tubes are connected to one another in parallel; and each vacuum glass heat collecting tube is connected with the water feeding main tube through a flow guiding tube, and is connected with the water draining main tube through a connecting tube. By using the novel solar heat collector, liquid is guided to deep portions of the total-glass vacuum solar heat collecting tubes, residual dirt in the vacuum tubes is drained by the flowing liquid, an end opening of each flow guiding tube has a corrugated structure, corrugated sections can be bent, the total-glass vacuum solar heat collecting tubes are convenient to mount and maintain, the corrugated flow guiding tubes are optimally matched with the inner walls of the total-glass vacuum solar heat collecting tubes, and the total-glass vacuum solar heat collecting tubes are not damaged during using and mounting.

Description

(1) Technical field [0001] The invention relates to solar water heaters, in particular to the field of heat collectors of solar water heaters. (2) Background technology [0002] At present, solar water heaters with the structure of all-glass vacuum glass collector tubes are composed of series collector tubes and parallel collector tubes. There is a diversion tube connected between the collector tube and the water inlet tube. The existing collector tube and diversion tube are inconvenient to install and troublesome to maintain. , it is easy to cause the rupture of the heat collection tube during installation, which greatly increases the cost; due to the arc shape of the nozzle of the all-glass vacuum solar heat collection tube, the existing technology uses a silicone sealing ring to directly seal, and the heat collection tube due to a small amount of displacement when the cavity is pressurized , will cause leakage; the pressure bearing capacity is poor and cannot meet the requi...

Problems solved by technology

[0002] At present, solar water heaters with the structure of all-glass vacuum glass collector tubes are composed of series collector tubes and parallel collector tubes. There is a diversion tube connected between the collector tube and the water inlet tube. The existing collector tube and diversion tube are inconvenient to install and troublesome to maintain. , it is easy to cause the rupture of the heat collection tube during installation, which greatly increases the cost; due to the arc shape of the nozzle of the all-glass vacuum solar heat collection tube, the existing technology uses a silicone sealing ring to directly seal, and the heat collection tube due to a small amount of displacement when the cavity is pressurized , will cause leakage; the pressure bearing capacity is poor and cannot meet the requirements of my country's civil tap water pipe network

Once the all-glass vacuum glass heat collecting tube is damaged, it will be unusable because the all-glass vacuum glass heat collecting tube cannot be replaced in time
