Abstract

The invention provides a multi-dimensional solar vacuum heat collecting tube which belongs to a heat exchange part, in particular to a part which utilizes the solar energy for heating. The multi-dimensional solar vacuum heat collecting tube comprises an outer tube and inner tubes, wherein, the inner tubes are suspended in the outer tube, a vacuum cavity is arranged between the outer tube and the inner tubes; the multi-dimensional solar vacuum heat collecting tube is characterized in that: the vacuum heat collecting tube comprises one outer tube and a plurality of inner tubes. As a plurality of inner tubes are arranged in the outer tube, the heat collection area is larger, the heat collection time efficiency is longer and the heating speed is faster; the production cost of the outer tube is simultaneously saved, so the multi-dimensional solar vacuum heat collecting tube has the advantages of high thermal efficiency and low production cost.

Description

technical field [0001] The invention belongs to a heat exchange component, especially a component heated by solar energy. Background technique [0002] The existing solar true tube heat collecting tube is usually composed of an inner tube and an outer tube, the inner tube is suspended in the outer tube, and a vacuum cavity is formed between the inner tube and the outer tube. In order to increase the heat collection effect, some also set a concentrating reflective surface between the inner and outer tubes, some set a solar heat absorbing film on the surface of the inner tube, and some add rods or blind tubes in the inner tube to reduce water storage and enhance convection effects and more. However, with the continuous improvement of science and technology, we believe that the thermal efficiency of existing solar vacuum heat collectors still has room for improvement, and the production cost also needs to be further reduced. Contents of the invention [0003] The purpose of...
