technical field

The utility model relates to the technical field of solar energy application, in particular to an interconnection mechanism for realizing modular connection of flat plate solar collectors.

Background technique

Flat-plate solar collectors are the core components of solar water heaters. In order to ensure sufficient thermal energy during installation and use, it is often necessary to interconnect multiple flat-plate solar collectors. A conventional flat-panel solar collector includes an upper header and a lower header. In the prior art, the inlet and outlet of the upper header and the inlet and outlet of the lower header are usually arranged on both sides of the collector, each protruding out. The length of the collector frame is about 50mm. When flat-panel solar collectors need to be interconnected, the connection methods between collectors are generally connected by special loose nuts, metal corrugated hoses, or high-pressure hoses and metal hose clamps. The above-mentioned connection process is relatively complicated, and there is a large gap between the interconnected heat collectors. The existence of connection parts and gaps makes it neither beautiful nor conducive to the realization of building integration when the collector is installed on the roof.

The connecting piece connects the upper circulation pipe inlet and the lower circulation pipe outlet of the front collector with the upper circulation pipe outlet and the lower circulation pipe inlet of the rear collector, and so on, until the connection is the most The last collector. The upper circulation pipe and the lower circulation pipe are only distinguished in use. The two are the same metal flow pipe, which is fixed on the heat absorption plate. When in use, the upper circulation pipe is the one that transports the heat medium to the water tank.

The lower circulation outlet and the upper circulation inlet of the last heat collector communicate with each other.

The upper circulation pipe outlet and the lower circulation pipe inlet of the front-most heat collector are used to connect with the hot water storage tank to form a solar circulation heating system

A preferred way is: the outlet of the upper circulation pipe of the heat collector and the inlet of the lower circulation pipe are protruded from the position close to one side of the upper frame of the heat collector; the inlet of the upper circulation pipe and the lower circulation pipe The outlet of the collector protrudes from the position of the lower frame of the collector close to the other side. Another preferred way is: the inlet of the upper circulation pipe and the outlet of the lower circulation pipe of the heat collector and the outlet of the upper circulation pipe and the inlet of the lower circulation pipe are all protruded from the upper frame or the lower frame of the heat collector, and are divided into two parts. located close to the sides.

The interconnection mechanism of the flat-plate solar collectors of the utility model provides a simple solution for the modular connection of the collectors, and the interconnected collectors can be abutted side-to-side to achieve seamless splicing, which is beneficial to avoid leakage Rain and other problems can replace roof building materials and realize building components.
