Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] image 3 It is a structural schematic diagram of the heat absorbing pipe of the first embodiment of the present invention. Such as image 3 As shown, the heat absorbing tube includes a glass tube 301 and a flexible heat conducting tube 309 inside the glass tube 301 .

[0035] The glass tubes are linear and can be connected in series with one or more.

[0036] The flexible heat pipe 309 has a heat-absorbing coating and is arranged parallel to the axis of the glass pipe. The flexible heat pipe 309 can be bent or bent in sections when it is outside the glass tube 301. After being fed into the glass tube 301, it is placed in a straight line, with both ends connected, and has the overall internal compensation function, that is, it has length compensation for thermal expansion and contraction.

[0037] The flexible heat pipe 309 may be a whole flexible corrugate...

Abstract

The invention discloses a solar heat-absorbing tube and a manufacturing method. The solar heat-absorbing tube comprises an outer layer of a glass tube, a flexible thermal-conductive tube and a positioning device, wherein, the flexible thermal-conductive tube penetrates a shaft line of the glass tube in parallel from the interior of the glass tube and is fixed by the positioning device. Compared with the existing solar heat-absorbing tube technology, the structure and the method have the following advantages: the heat absorption efficiency is high; the impact of thermal expansion and contraction on the thermal-conductive tube is small, and the operation is stable and reliable; the structure and the manufacturing method are simple, the cost is low, the installation and the maintenance are very convenient, thereby being very applicable to large-scale popularization and application; the heat exchange effect of a thermal-conductive medium is strong, the heat transfer is faster, and the mixed flow phenomenon existed in a blind pipe can be avoided.

Description

technical field [0001] The invention relates to the technical field of solar heat utilization, in particular to a solar heat absorbing pipe structure and a manufacturing method thereof. Background technique [0002] As a clean and environment-friendly energy source, people have been devoting themselves to the development and utilization of solar energy for a long time. Especially in recent years, due to rising oil prices and the requirement to reduce carbon emissions, countries have worked harder to carry out research on solar energy utilization. In the promotion of light and heat utilization, the production efficiency and installation convenience of solar heat absorbing tubes , operational reliability and cost reduction put forward higher requirements. [0003] In recent years, the use of solar heat absorbing tube technology in some specific environments has been developed. figure 1 A heat absorber arrangement mainly used in atmospheric environment is illustrated. The ab...
