A collector type solar water heater

Abstract

The invention relates to a heat collection type solar water heater. The heat collection type solar water heater comprises a heat collection assembly and a heating assembly, wherein the heat collection assembly comprises a light collection plate and a light guide base; the light guide base comprises a light guide drum; a convex lens is arranged on the light guide drum; the light guide plate is fixed at one end part of the light guide drum; the cross section of the light collection plate is in the shape of a circular arc; a plurality of light reflecting surfaces are linearly arranged on the light collection plate and face toward the light guide drum; a light outlet is formed in the other end of the light guide drum; sunlight is reflected to the convex lens from the light reflecting surfaces and is focused at the light outlet through the convex lens; the heating assembly comprises a connecting drum fixedly connected to the light guide drum; a heat collecting drum with the annular cross section is arranged in the connecting drum; an annular heat collecting cavity is formed in the heat collecting drum; a light transmitting hole corresponding to the light outlet is formed in the annular middle part of the heat collecting drum; the heat collecting drum is made from a light transmitting material; the sunlight focused at the light outlet irradiates the annular inner wall of the heat collecting drum through the light transmitting hole; and infrared rays in the sunlight heat water in the heat collecting cavity.

Description

technical field [0001] The invention relates to a heat-collecting solar water heater, which belongs to the field of solar energy equipment. 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 by the present invention is to overcome the technical problem of exposed heat collecting tubes in the prior art, and provide a h...
