Embodiment Construction

[0023] Such as figure 1 Shown is an axially moving temperature-controlled glass heat pipe provided by the present invention. The glass heat pipe includes a cover glass tube 1 and an inner tube 2. The lower end of the inner tube 2 is a heat collecting end, and the upper end is a condensing end 3. A heat-absorbing working fluid 4 is placed in the heat collecting end of the inner tube 2, the cover glass tube 1 is welded to the inner tube 2 through a ring seal 5, and the cover glass tube 1 is connected to the inner tube 2. A vacuum interlayer 6 is formed between the heat-collecting ends of the tubes 2, and a getter 8 is fixed inside the vacuum interlayer 6 with clips 7. When sunlight passes through the cover glass tube 1 and shines on the heat-collecting end of the inner tube 2 In the process, the working medium 4 will be vaporized by heat and then evaporated to the condensation end 3, and the gasified working medium 4 will condense into a liquid state again after releasing heat a...

Abstract

The invention provides an axial-movement temperature-controlled glass heat tube which comprises a glass tube and an inner tube. The lower end of the inner tube is a heat collection end, and the upper end of the inner tube is a condensation end; a temperature-controlled telescopic sealing element is arranged in the condensation end of the inner tube and comprises a support fixed in the inner tube, the lower portion of the support is connected with a heat deformation piece which can move in a telescopic mode in the axial direction of the inner tube, and the lower end of the heat deformation piece is further connected with a sealing element; the inner wall of the condensation end of the inner tube is further provided with an annular sealing step of a necking shape, and a gap is kept between the sealing element of the heat deformation piece and the upper side of the sealing step. By arranging the sealing step and the temperature-controlled telescopic sealing element in the inner tube of the glass heat tube, intercepting and releasing working media can be automatically achieved at set temperature, and then the purpose that the temperature of the glass heat tube can be controlled is achieved.

Description

technical field [0001] The invention relates to a solar heat collection tube structure, in particular to an all-glass heat pipe vacuum solar heat collection tube. Background technique [0002] The all-glass heat pipe vacuum solar collector tube (referred to as glass heat pipe) is the key heat-absorbing element of the solar water heating system and an important part of the solar water heating system. The all-glass heat pipe vacuum solar collector tube is mainly composed of a cover glass tube and an inner tube with a selective absorbing coating. This kind of heat collecting tube can easily absorb solar energy when there is sunlight, and convert it into heat energy and transmit it to the heat storage system. [0003] However, when the above-mentioned solar water heating system does not operate for several days due to some reasons, the solar collector tubes continuously absorb solar energy and convert it into thermal energy. This can easily cause the system to overheat, and ev...
