Problems solved by technology
[0004] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a variable-area phase-change sleeve solar panel solar collector, which solves the problem of the flat panel collector under extreme conditions such as strong radiation, large temperature difference, and low pressure in plateau areas. There are frequent and large fluctuations in the temperature of the fluid in the collector, which makes flat-plate solar collectors prone to damage such as freezing cracks and overheating. Heat dissipation from solar collectors to the environment, improving heat utilization efficiency

Abstract
A variable-area phase-change sleeve solar panel solar collector, comprising a frame, a heat-absorbing plate is arranged inside the frame, and a transparent cover is sealed on the upper side of the heat-absorbing plate, and the transparent cover is located on the At the upper port of the frame, an insulation layer is provided on the lower side of the heat-absorbing plate. The heat-absorbing plate is provided with a fluid pipeline. The fluid pipeline and the phase-change pipeline adopt concentric sleeves, and the phase-change pipeline is located inside the fluid pipeline. The invention solves the problem of frequent and large temperature fluctuations of the fluid temperature in the collector under extreme conditions such as strong radiation, large temperature difference, and low air pressure in the plateau area, which makes the flat-plate solar collector prone to frost cracking, overheating and other damages. At the same time, it can reduce the contact thermal resistance of PCM in the collector tube and reduce the temperature of the heat absorbing plate, thereby reducing the heat dissipation of the solar collector to the environment and improving the heat utilization efficiency.
Description
technical field [0001] The invention relates to the technical field of solar light and heat utilization, in particular to a variable-area phase-change sleeve solar panel solar collector. Background technique [0002] Solar energy is an inexhaustible, non-polluting and clean energy. As a renewable energy source, it occupies an important position in the national energy structure. Especially in the western plateau solar energy-rich areas, the use of solar energy for heating and hot water has become the norm. . The use of solar collectors to collect, store, and utilize solar energy with low energy flow density and discontinuous fluctuations can effectively improve the stability of solar energy utilization. Existing solar collectors are mainly divided into vacuum tubes (all glass vacuum tubes, U-shaped tubes, heat pipes, etc.) In 2008, especially large-scale flat-panel solar collectors were widely used in solar heating projects on the Qinghai-Tibet Plateau. High-efficiency larg...
