Embodiment Construction
[0022] figure 1 A first embodiment of the present invention is given.
[0023] figure 1 Among them, the cover glass tube 1 and the inner glass tube 2 are concentrically nested and sealed to form a vacuum solar heat collecting element with a low-set short tube liquid-absorbing core 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. The length of the hot end of the heat pipe 3 is 1.8 meters. The outer surface of the inner glass tube 2, that is, the heat pipe 3, is made with an absorbing film. The integrated glass heat pipe solar heat collecting element is installed vertically or obliquely. Heat pipe 3 relies on gravity to work. The inside of the hot end of the heat pipe 3 is provided with a short tube liquid-absorbing core 4, the length of the short tube liquid-absorbing core 4 is 60 mm; The short tube liquid-absorbing core 4 is arrange...

Abstract
A glass heat-tube vacuum solar heat accumulation component integrated with a low-arranged short-barrel liquid absorbing core is manufactured by a cover glass tube and an inner glass tube which are concentrically nested and disposed in a seal manner. The inner glass tube extends forwards from the sealed joint and is sealed to form a branch heat tube after being vacuumized internally and filled with working medium. The glass heat-tube vacuum solar heat accumulation component is characterized in that the short-barrel liquid-absorbing core is arranged at the inner bottom end of a hot end of a glass heat tube. A glass heat-tube vacuum solar heat accumulation component with a low-arranged short-barrel liquid-absorbing core inserted is manufactured by a full-glass vacuum heat accumulation tube and an inserted glass heat tube inserted into an inner cavity of the inner glass tube in a matched or low-thermal-resistance connection manner. The glass heat-tube vacuum solar heat accumulation component with the low-arranged short-barrel liquid-absorbing core is characterized in that the short-barrel liquid-absorbing core is contained in a hot end of the heat tube. Generally, the short-barrel liquid-absorbing core is 60milimeters in length. Starting time of the heat tube in winter is shortened to about 20 minutes from 140 minutes of original light tubes and heat tubes, and working medium filling quality is kept fundamentally constant so as to guarantee safety of the heat tube during air drying.
Description
technical field [0001] The invention relates to a vacuum solar heat collecting element of a glass heat pipe with a low-set short tube and a liquid-absorbing core. Background technique [0002] The solar water heater made of heat pipe vacuum heat collecting tube has the advantages of high energy efficiency ratio without water in the tube, conforms to the sanitary drinking water standard, 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 ...
