Abstract

The invention relates to a solar heat collector, which sequentially consists of a heat insulation layer, working medium, a metal substrate, an absorption membrane and a low-radiation module from the bottom layer to the top layer; the heat insulation layer is arranged on the bottom layer of the heat collector; the upper part of the heat insulation layer is wrapped by a copper medium pipe or a copper medium cavity for holding the working medium, and the medium pipe or the medium cavity is distributed and welded on the lower part of the metal substrate; and the absorption membrane is precipitated on the upper part of the metal substrate, and the low-radiation module covers the upper part of the absorption membrane. The low-radiation module sequentially consists of coated glass, a low-emissivity membrane which is precipitated on the coated glass, a hollow layer which is arranged above the low-emissivity membrane, a sealing strip supporting the hollow layer and an upper layer of glass which is connected with the sealing strip and arranged above the hollow layer. Due to the adoption of the flat-panel solar heat collector, the performance and the efficiency of the flat-panel solar heat collector can be remarkably improved, and the application range of the flat-panel solar heat collector is greatly enlarged.

Description

technical field [0001] The invention relates to a solar heat collector, in particular to a flat plate heat collector suitable for various high, medium and low temperature solar heat utilization, and belongs to the technical field of solar energy. technical background [0002] The energy problem is one of the most prominent problems faced by the whole world, and solar energy is an inexhaustible and inexhaustible clean energy source for human beings. Solar heat conversion is the most popular and main form of solar energy utilization in the world, and the most representative one is solar water heater. my country has become the country that produces the most solar water heaters in the world, and also has the world's largest solar water heater market.
