Embodiment Construction
[0009] figure 1 In this method, a natural circulation channel is formed by the ascending pipe 1, the descending pipe 2 and the tubular heat release end 3, and the ascending pipe 1 of the natural circulation passage is embedded in an all-glass vacuum heat collecting tube and is connected with the inner glass tube 4 of the heat collecting pipe by means of transmission. The heat transfer fins 5 form an embedded vacuum circulation heat collecting element.
[0010] figure 1 Embodiment Embedded vacuum cycle heat collecting elements are installed obliquely at the high position of the heat release end 3 in sunlight, so that the liquid surface of the heat medium shown by the oblique dotted line is in a horizontal state. The sunlight passes through the cover glass tube and is converted into heat energy on the absorption film of the inner glass tube 4 of the heat collecting tube. The tube 1 floats up, and at the tubular exothermic end 3 of the natural circulation flow channel, the heat...

The invention provides an embedded vacuum circulating heat-collecting component. The component is characterized by comprising a natural circulating channel formed by an ascending tube, a descending tube and a heat release end, wherein a heat transfer fin is arranged between the ascending tube of the natural circulating channel and an inner glass tube of an all-glass vacuum heat-collecting tube. The invention has the following beneficial effects: in the places where a collector can be obliquely or vertically mounted, the embedded vacuum circulating heat-collecting component dispenses with power for circulating heat transfer, is started quickly, resists frost, is free from tube explosion, can still collect heat even if a single tube is damaged, and can be used for manufacturing a solar heat collector which can produce water with quality in line with the hygienic standard, can gain more heat and has excellent heat insulation property; and a heat exchange interface is freely designed, and the heat-collecting component is insensitive to the vacuum degree, can semi-permanently and stably work at the temperature of 20-500 DEG C and can use low-carbon steel and aluminium to replace copper. An embodiment is given in the invention in combination with the drawing.
Description
technical field [0001] The invention relates to an embedded vacuum circulation heat collecting element. Background technique [0002] Vacuum intubated solar water heaters can provide domestic hot water in winter, but there is a large heat sink in the collector tube, less heat gain, poor frost resistance, tube explosion, water leakage if a single tube is damaged, and excessive water quality degradation bacteria. Heat pipe heat collecting elements can be used to manufacture water heaters without water in the pipes, but copper-water heat pipes are expensive, easy to freeze, and some have obvious performance degradation. Contents of the invention [0003] The object of the present invention is to provide an embedded vacuum circulation heat collecting element. [0004] The technical scheme adopted by the present invention to solve its technical problems: a natural circulation flow channel is formed by the upward pipe, the downward pipe and the heat release end, the natural cir...
