Double-pass bamboo-shaped solar collector tube

Abstract

The invention discloses a double-pass bamboo-shaped solar collector tube. The tube comprises a plug, outer tubes and inner tubes, wherein the inner tubes respectively sleeve in the outer tubes; the plug is connected between the outer tubes; a double-pass bamboo joint is connected between the inner tubes; an angle measuring instrument is arranged on the surface of the plug; and heat conducting media are arranged in the inner tubes and connected with the bottoms of the inner tubes through rotating shafts. The solar collector tube disclosed by the invention has the beneficial effects that water in two solar collector pipes can be communicated through the double-pass bamboo joint to guarantee the heating uniformity of a solar water heater; angles of the heat conducting media in the solar collector tubes can be adjusted to ensure that heat of the sun can be absorbed to the maximum extent by the solar collector tubes; the firmness between the solar collector tubes can be increased to avoid the deformation of the solar collector tubes when used for a long time and guarantee the using effect of the solar collector tubes; and the heat absorption effect of the solar collector tubes can be increased.

Description

technical field [0001] The invention relates to a solar heat collecting tube, in particular to a double-pass bamboo solar heat collecting tube. Background technique [0002] A solar collector is a device that absorbs solar radiation and transfers the generated heat energy to a heat transfer medium. In the heat utilization of solar energy, the key is to convert the sun's radiant energy into thermal energy. Since the solar energy is scattered, it must be concentrated. Therefore, the heat collector is a key part of various solar energy devices. The solar heat collector is internally connected with a solar heat collecting tube. [0003] When the solar collector tube is in use, it is more or less single tube, which causes uneven heat of the heating water, which brings inconvenience to the use of the solar collector tube, lacks the adjustment of the heat absorbing device inside the solar collector tube, and cannot guarantee the maximum heat absorption, and The single-layer heat ...
