Embodiment Construction
[0027] figure 1 A first embodiment of the present invention is given.
[0028] figure 1Among them, the cover glass tube 1 and the inner glass tube 2 are concentrically nested and sealed to form a heat collecting element with a sparse core network to accelerate the start-up of the integrated glass heat pipe. The inner glass tube 2 protrudes forward from the sealing joint, and the inside is evacuated and filled with working fluid, and then sealed to form a heat pipe 3 . An absorbing film is made on the outer surface of the inner glass tube 2 . The sparse core net accelerates the vertical or oblique installation of the heat collecting element activated by the integrated glass heat pipe. Heat pipe 3 relies on gravity to work. Ten ring-shaped narrow capillary cores 4 arranged in the circumferential direction are arranged inside the hot end of the heat pipe 3 to form a sparse core network. The annular narrow capillary core 4 is pressed against the inner wall of the hot end of t...

The invention relates to a heat collection element for accelerating start-up of an integrated glass heat pipe through a sparse core net. The heat collection element is formed by a glass shielding pipe and an inner glass pipe in a concentrically embedding and sleeving manner, wherein the inner glass pipe extends forwards from the sealing part and is manufactured into a heat pipe; and the heat collection element is characterized in that the sparse core net formed by a plurality of thin capillary liquid absorption cores with the width of 2-10 mm is arranged in the interior of the hot end of the heat pipe. The invention further provides a heat collection element for accelerating start-up of an inserted glass heat pipe through a sparse core net. The heat collection element is formed by an all-glass vacuum heat collecting pipe and the inserted glass heat pipe in a low-thermal resistance connecting way; and the heat collection element is characterized in that the sparse core net formed by a plurality of thin capillary liquid absorption cores with the width of 2-10 mm is arranged in the interior of the hot end of the inserted glass heat pipe. According to the invention, as the sparse core net is arranged on the inner wall of the heat pipe, the starting time of the heat pipe is shortened to more than 10 minutes from more than 140 minutes of the starting time of the original pipe without the sparse core net, the energy efficiency ratio of the heat collection element for the vacuum heat pipe is greatly improved, and the filling volume of the working medium of the heat pipe is not increased basically, and furthermore, the vapor pressure inside the heat pipe during air drying is also not increased basically.
Description
technical field [0001] The invention relates to a heat collecting element for accelerating the start-up of a glass heat pipe with a sparse core net. Background technique [0002] The solar water heater made of heat pipe vacuum heat collecting tube has the advantages of no water in the tube, conforms to the sanitary drinking water standard, high energy efficiency ratio, and can work as usual if a single tube is damaged. therefore. The solar vacuum water heater without water in the tube will likely occupy more and more market share. [0003] Existing a kind of workload fills seldom all-glass heat pipe vacuum heat collecting tube solar water heater, and heat pipe inner wall adopts light pipe structure, and heat pipe vacuum heat collecting tube is installed with an inclination of about 45 degrees. In the non-heat exchange state, it can be observed that there is accumulation of liquid working fluid at the bottom of the heat pipe. [0004] A comparative test was carried out on...
