A double-concave honeycomb cavity hollow structure solar heat collector

Abstract

The invention relates to a solar heat collector of a biconcave honeycomb cave hollow structure. The solar heat collector comprises a heat collector plate core, a light-transmitting cover plate, a heat preservation layer and a frame. The bottom of the heat collector plate core is embedded into the heat preservation layer, the upper surface of the heat collector plate core is covered with the light-transmitting cover plate, a back plate is arranged at the bottom of the heat preservation layer, the heat collector plate core is composed of a sunny panel and a bearing panel, the sunny panel and the bearing panel are in smooth connection and are sealed on the peripheries, and therefore a hollow interlayer is formed between the sunny panel and the bearing panel, and the sunny panel is a honeycomb panel formed by a plurality of concave honeycombs. A water inlet and a water outlet are formed in the back of the bearing panel. The honeycomb cave design is adopted, so that the effective illumination area of the solar heat collector is improved by more than 1.8 times, and the capacity of absorbing sunlight radiation is improved. Sunlight irradiates the inner walls of the concave honeycombs, and is absorbed, reflected and absorbed by the inner walls many times, and almost all the sunlight radiation can be absorbed.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to a solar heat collector with a double concave honeycomb cavity hollow structure. Background technique [0002] The solar collector absorbs the light radiation energy of sunlight through the heat absorbing layer, and converts the solar energy into heat energy by using the principle of the greenhouse effect. Although the solar collector is not a terminal product directly facing consumers, the solar collector is a key component of various solar heat utilization systems. Whether it is solar water heaters, solar cookers, active solar houses, solar greenhouses or solar drying, solar industrial heating, solar thermal power generation, etc., solar collectors are inseparable, and solar collectors are used as the power or core components of the system. of. [0003] Existing solar heat collectors are mainly flat-plate solar heat collectors, which mainly include a housing, ...

AI Technical Summary

Problems solved by technology

This kind of heat collector, because its heat conduction plate is a flat structure, is easy to cause light reflection, and the absorption efficiency of the heat absorbing layer on the solar radiation energy is not high; Small, not conducive to the absorption of solar radiation energy
