Embodiment Construction

[0011] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0012] Such as figure 1 , figure 2 The blade-type solar collector tube shown includes a circular glass heat collector tube. The tube wall of the heat collector tube is a vacuum-tight tube wall of double-layer glass with a spectrally selective coating 2 inside, and the outer tube wall 1 and the inner tube wall 3. Seal to form a vacuum tube wall. Both ends of the heat collecting tube are open, and the two ends can be directly connected to the water pipe; there are multiple rotating parts in the axial direction of the heat collecting tube, and each rotating part is made of a transparent resin that is arranged axially with the heat collecting tube. The round rod 4 is uniformly provided with six transparent resin blades 5 in the radial direction, and the blades 5 shrink from the connection with the round rod 4 to the tail of the arc; when the water in...

Abstract

The invention discloses a blade type solar heat collection tube. The blade type solar heat collection tube comprises a round glass heat collection tube, and the tube wall of the heat collection tube is a vacuum sealing tube wall of double-layer glass internally provided with a spectral selective coating; the two ends of the heat collection tube are open, a plurality of rotating pieces are axiallyand sequentially arranged in the heat collection tube, each rotating piece comprises a round rod arranged in the axial direction of the heat collection tube and made of transparent resin, a pluralityof transparent resin blades are radially and uniformly arranged on each round rod in the radial direction, and each blade is shrunk from the connecting position between the blade and the correspondinground rod to the tail part of the blade in an arc shape; the diameter of each round rod is smaller than two percent of the inner diameter of the heat collection tube, and the maximum thickness of each blade is smaller than one fifth of the diameter of the corresponding round rod; and when water in the heat collection tube is heated to flow, the pressure generated by flowing of the water drives the rotating pieces to slightly rotate. According to the blade type solar heat collection tube, the problems that an existing solar heat collection tube is uneven in heating and not high in heating efficiency can be solved.

Description

technical field [0001] The invention relates to the technical field of solar heat collection, in particular to a vacuum heat collection tube for collecting solar energy. Background technique [0002] Existing vacuum heat collecting tubes for collecting solar energy generally include a circular glass heat collecting tube, the tube wall of the heat collecting tube is a vacuum glass double-layer tube wall with a spectrally selective coating inside, and one end of the heat collecting tube is open, and the coating can be Selectively absorbs the solar spectrum to maximize the absorption of solar radiation energy. After being irradiated by sunlight, photons hit the coating, and the solar energy is converted into heat energy. The water absorbs heat from the outside of the coating, the temperature of the water rises, the density decreases, and the hot water moves upward, while the cold water with a large specificity drops, so the water temperature in the upper part of the heat collec...
