Stainless steel insulating pipe for solar heat collector

Abstract

The invention discloses a stainless steel insulating pipe for a solar heat collector. The stainless steel insulating pipe comprises an L-shaped stainless steel inner pipe, wherein one end of the L-shaped stainless steel inner pipe is provided with a flange plate connected with an oil way, the other end of the L-shaped stainless steel inner pipe is a vacuum pipe connecting end, two layers of corrugated pipes are sleeved outside the stainless steel inner pipe, close to the flange disc; and an air gel layer is arranged between the two layers of corrugated pipes, a stainless steel outer pipe is sleeved outside the other part of the stainless steel inner pipe, and the air gel layer is filled between the stainless steel outer pipe and the stainless steel inner pipe. The stainless steel insulating pipe provided by the invention has the beneficial effects that the heat preservation effect is good, the construction is convenient and rapid, the energy consumption is low, the mutual displacement of a pipeline or a machine and an equipment connecting end are compensated, the vibration energy is absorbed, and the stainless steel insulating pipe can play roles of vibration damping and noise reduction and the like; and the stainless steel insulating pipe has multiple properties such as good flexibility, small mass, corrosion resistance, fatigue resistance, and high temperature and low temperature resistance.

Description

technical field [0001] The invention relates to a stainless steel insulation pipe for a solar heat collector, which is connected between an oil passage and a vacuum pipe. Background technique [0002] At present, the vacuum tube on the solar collector and the oil circuit need to be connected by pipelines, and the general pipeline insulation performance is relatively poor. If no insulation measures are taken, the heat dissipation of the pipeline will be large, resulting in the heat collected by the collector. Wasted in vain, reducing the effectiveness of the equipment. In addition, since the solar heat collector needs to be deflected by chasing the sun, the general pipeline will vibrate greatly, and the connection strength will be reduced. Contents of the invention [0003] In order to solve the above technical deficiencies, the present invention provides a stainless steel heat preservation pipe for solar collectors with good thermal insulation performance and the function...
