Solar heat-collecting panel core and solar heat-collector using same

Abstract

The invention discloses a solar heat-collecting plate core and a solar collector using the same. The heat-collecting plate core is formed by at least one hollow cavity body structure both ends of which are opened, wherein, the hollow cavity body structure consists of a transmission layer which is arranged on the outside surface of a cavity body and a heat-absorbing layer which is arranged inside the cavity body or the outside surface of the cavity body; and the heat-absorbing layer and the transmission layer are arranged oppositely. The solar collector comprises a shell the back and the circumference of which are provided with heat-insulating material layers, wherein, the shell is provided with the heat-collecting plate core, a thermal medium outflow channel and a thermal medium inflow channel which are respectively arranged on the upper end and the lower end of the heat-collecting plate core. When the heat-collecting plate core is filled with water, the transmission layer and a water layer play a part in increasing transmission and reducing reflection, thereby the solar energy loss is reduced. Moreover, a heat dissipation channel of the heat-absorbing layer can be blocked by the heat-insulating material layers and the water layer and heat flows are quickly carried away by flowing water, thereby the solar heat-collecting plate core and the solar collector using the same have the advantages of effective heat collection, low heat dissipation loss and high heat-collecting efficiency.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a solar heat collecting plate core and a solar heat collector using the heat collecting plate core. Background technique [0002] As far as the prior art is concerned, the vacuum tube heat collector is suitable for medium and high temperature heat collection. Although it has high performance, it is expensive, heavy, and inconvenient to install and carry. The tube plate collector is suitable for medium and low temperature heat collection, the price is relatively moderate, and it is generally used more, but its disadvantage is that the heat collector core is generally made of copper-aluminum or copper-aluminum composite, the price is still high, although The surface temperature of the black surface is very high, but because the heat source black surface of the collector is directly exposed to the environment, its heat dissipation loss is relatively large and the th...

[0002] As far as the existing technology is concerned, the vacuum tube heat collector is suitable for medium and high temperature heat collection. Although it has high performance, it is expensive, heavy, and inconvenient to install and carry.

The tube plate collector is suitable for medium and low temperature heat collection, the price is relatively moderate, and it is generally used more, but its disadvantage is that the heat collector core is generally made of copper-aluminum or copper-aluminum composite, the price is still high, although The surface temperature of the black surface is very high, but because the heat source of the collector, the black surface is directly exposed to the environment, so its heat dissipation loss is relatively large and the thermal efficiency is low

Moreover, since the materials used in vacuum tube collectors and tube-sheet collectors are mostly metal materials, and the shapes are different, it is difficult to integrate with the building itself, which affects the aesthetics of the building
