Abstract

The invention relates to a low thermal resistance flat solar heat collector that is made up of heat collecting board, cycle frame, and thermal insulation box. The heat collection board is joint on the cycle frame and the cycle frame is installed in the thermal insulation box. The advantage is that the cycle frame effectively reducing the thermal resistance of the solar energy collector, increases the contra flow speed of cold water and hot water, and improves the heat efficiency of the solar water heater. The invention is simple structure, low cost and is suited for mass production.

Description

Technical field: [0001] The invention relates to a solar heat collector, in particular to a flat solar heat collector with low thermal resistance. technical background: [0002] In the existing flat solar heat collector, since the water collecting pipe is horizontally installed in the heat preservation box, when the flat solar heat collector is working, it takes a long time for the hot water in the water collecting pipe to move out of the water collecting pipe, and its large thermal resistance , which hinders the further improvement of the thermal efficiency of this type of collector. Invention content: [0003] The purpose of the present invention is to provide a low thermal resistance flat solar heat collector. It consists of a heat collecting plate, a circulation frame, and a heat preservation box. The heat collection plate is welded on the circulation frame, and the circulation frame is installed in the heat preservation box. [0004] The heat collecting plate of the...
