Problems solved by technology

Its disadvantages are: when in use, the upper circulation header, the lower circulation header and the heat collection pipe are filled with water, and it is easy to freeze and crack the upper circulation header, the lower circulation header or the heat collection pipe in cold weather. In some direct circulation systems, due to the influence of scale, the heat collecting tube is easy to block the structure, and scale is a poor conductor of heat, and the existence of scale affects the thermal efficiency of the collector

Abstract

A thermal tubular panel style solar energy collector consists of upper circulating pipes, lower circulating pipes, and heat collecting pipes, which are equipped with heat-exchanging ribs, connected with them. One at least exchanging pipe is installed in the upper circulating pipes and with both ends extending out. The chamber sealed by the said pipes is filled with liquid media, which is converted between gas and liquid phases to transfer heat energy. It works efficiently and weatherproof in cold winter and with no scales inside.

Description

Technical field [0001] The invention relates to a heat collection device that converts the light energy of the sun into heat energy, and belongs to the technical field of solar heat utilization devices. Background technique [0002] In the prior art, there is a widely used flat-plate solar collector, which is mainly composed of an upper circulation header, a lower circulation header, a heat collection tube, and a heat collection fin. It is connected by a number of heat collection tubes. The heat collection fins are arranged on both sides of the heat collection tube. The upper circulation header is provided with a water outlet, and the lower circulation header is provided with a water inlet. When in use, the upper circulation header and the lower The circulating header and the heat collecting tube are filled with water. The water enters the lower circulating header from the water inlet. The solar-irradiated heat collecting tube and heat collecting fins absorb heat and transfer hea...
