Embodiment Construction
[0005] Explain in conjunction with accompanying drawing Fig. 1, Fig. 2:
[0006] First make a metal tube with a diameter slightly larger than the inner diameter of the vacuum tube and with vertical wrinkles, as shown in Figure 1, the wrinkles or elastic grooves (2) can shrink the metal tube, making the metal tube elastic, and this elastic force makes the elastic metal tube After being shrunk, it can be smoothly inserted into the vacuum tube, and can be tightly combined with the inner wall of the vacuum tube after being relaxed. A cavity is formed in the metal tube, and division is carried out in this cavity at the same time, such as the division layer (3). Form a plurality of cavities like this, (4) among Fig. 2, in Fig. 2, dividing layer (1) has corrugation namely elastic groove (2), and elastic groove (3) makes dividing layer (1) have elasticity.
[0007] Metal tubes can be made of steel tubes, aluminum tubes, copper tubes and various metal alloys. The side in contact with ...

The invention relates to a multi-stage elastic heat tube in a solar vacuum tube, belonging to a high-efficiency heat transmission tube in a solar vacuum tube, which mainly solves the problem that a heat tube is used in a solar vacuum tube in a mating mode currently to realize low cost and high efficiency transmission. The manufacturing method of the elastic heat tube mainly comprises the following steps: firstly manufacturing a metal tube with vertical wrinkles, of which the diameter is a little larger than the inner diameter of the vacuum tube, and enabling the metal tube to have shrinkable and tensile elasticity so that the elastic metal tube can be smoothly inserted into the vacuum tube by the elasticity after shrinking and can be tightly combined with the inner wall of the vacuum tube after releasing, wherein a cavity is formed in the metal tube, the cavity is simultaneously divided into multiple cavities, and all the cavities are respectively filled with heat transmission liquids of different boiling points or have different pressure settings, namely different required vacuum degrees, to enable each cavity to be activated at different temperatures and to transmit in different temperature ranges of low temperature, moderate temperature, high temperature and the like so as to form the multi-stage elastic heat tube. The invention can be widely applied to water heaters and moderate-high temperature heat utilization systems.
Description
[0001] Technical field: heat transfer field of heat pipes for solar thermal utilization Background technique: [0002] Vacuum tube technology and heat pipe technology have been highly developed at present, but there are few heat pipe technologies matching the current vacuum tubes, especially heat pipes that have high heat transfer efficiency, low cost, and can be used for medium and high temperatures. Invention content: [0003] First of all, make a metal tube with a diameter slightly larger than the inner diameter of the vacuum tube and with vertical wrinkles, so that the metal tube has the elasticity of contraction and stretching. This elastic force makes the elastic metal tube shrink and insert into the vacuum tube smoothly, and after relaxation, it can be tightly connected to the inner wall of the vacuum tube. Combined, a cavity is formed in the metal tube, which is divided into multiple cavities at the same time. Each cavity is filled with heat transfer liquids with diff...
