Abstract

The invention relates to the fields of environmental protection and energy conservation and discloses a light collecting device for a solar water heater. The light collecting device comprises an accommodating cavity with an opening, a light energy collecting metal tube, a transparent glass plate and a transparent heat concentrating layer, wherein the light energy collecting metal tube is arrangedin the accommodating cavity and is used for circularly heating water; the transparent glass plate is adhered to the opening; the transparent heat concentrating layer is arranged on the transparent glass plate and is used for improving the temperature of the transparent glass plate so as to prevent from forming water mist; a heat insulation space is formed between the accommodating cavity and the transparent glass plate; and by circularly heating water through the light energy collecting metal tube, scales cannot be formed and the service life of the product is prolonged. Particularly, the light energy collecting metal tube comprises a plurality of stainless steel tubes arranged in parallel, and a light heat absorption layer is arranged on the surface of each stainless steel tube. The stainless steel tubes of which the surfaces are provided with the light heat absorption layers absorb light energy to circularly heat the water, and have the function of expanding with heat and contracting with cold; and the scales cannot be formed in the tubes at all.

Description

technical field [0001] The invention relates to the field of environmental protection and energy saving, in particular to a light and heat collection device for a solar water heater. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the use of water heaters is becoming more and more popular; and solar water heaters are more widely used due to their energy-saving and environmental protection features. [0003] At present, common solar water heaters are roughly divided into two types: one is a water heater in which a solar collector vacuum glass tube is directly inserted into an insulated water tank; the other is a heat pipe pressure-bearing water heater. But the weak point of prior art solar water heater is: when running into fine weather, water temperature rises very high, can bathe normally; Descaling. [0004] Therefore, the prior art still needs to be improved and developed. Contents of the i...
