Concentrating solar water heater

Abstract

The invention relates to a concentrating solar water heater. The concentrating solar water heater comprises a concentrating assembly and a heating assembly. The concentrating assembly comprises a concentrating panel. The concentrating panel comprises a spherical reflection plate. A light reflection layer is arranged on the surface of the reflection plate. A retrorefelctor is connected with the reflection plate through supports and located in the spherical center of the spherical reflection plate. A light collecting barrel is arranged in the spherical center of the concentrating panel. A light collecting lens is arranged at one end of the light collecting barrel and located on the face, provided with the reflection layer, of the concentrating panel. A concentrating assembly body is arranged on the other end of the light collecting barrel. The concentrating assembly further comprises a light guide barrel installed in the light collecting barrel. A concentrating lens is installed in the light guide barrel. A refractor is further arranged in the light guide barrel. The heating assembly comprises a connecting barrel fixedly connected with the light guide barrel. A heat collecting barrel with the annular section is arranged in the connecting barrel. An annular heat collecting cavity is formed in the heat collecting barrel. Light holes are formed in the annular middle portion of the heat collecting barrel.

Description

technical field [0001] The invention relates to the field of solar energy equipment, and belongs to a concentrating solar water heater. Background technique [0002] The heat collecting tube solar water heater is connected to a water tank through several heat collecting tubes. The heat collecting tubes are used to receive the infrared rays in the sunlight to circulate and heat the hot water in the heat collecting tubes, so as to achieve the purpose of hot water. In order to ensure good light transmission The heat collector tube is generally made of glass, so it is relatively fragile. The heat collector tube is generally directly exposed to the environment. Once it encounters hail or severe weather with a large temperature difference, it is easy to break and cause danger. . Contents of the invention [0003] The technical problem to be solved in the present invention is: [0004] The invention overcomes the technical problem of exposed heat collecting tubes in the prior a...
