Non-condensing hot water Direct heating type Natural circulation Solar water heaters Collectors and collectors, Connections between collectors and storage tanks

摘要

The present invention relates to a connection structure between a collector and a collector of a non-freezing hot water direct-heating type naturalization solar water heater, or a connection structure between a collector and a storage tank, more particularly, a pipe connecting a collector and a collector or a storage tank with a relatively good thermal conductivity Copper, etc. In order to prevent the freezing of the inside of the pipe, the silicone rubber tube is inserted and the tube is always positioned at the center of the pipe so that the water flows smoothly and the outer surface of the connecting pipe is covered with the heat insulating material, Which is prevented from being damaged due to a freezing wave.;That is, a pipe 22 connecting the collector 14 and the collector 14 or a silicon rubber tube 24 having both ends clogged inside the pipe 26 connecting the collector 14 and the thermal storage tank 16 Instead, a silicone rubber tube (24) is inserted inside the pipe (for example, a polyurethane or polyethylene tube can be used if it is softly made of a heat-resistant and resilient material within a solar application range of-20C to 90C) The fixing member 30 is attached to both ends of the pipe so as to be located at the center, and both ends of the silicone rubber tube are pulled and fixed or The rings of the shape are inserted at regular intervals Repeatedly place the rings of the shape at regular intervals so that the protruding parts of the ring face the 12 o'clock, 3 o'clock, 6 o'clock and 9 o'clock directions. A spring 28 having a small inner diameter is used to spring the silicon rubber tube 24 and a spring 28 having a large inner diameter is used to press the inner wall 24 of the pipes 22 and 26, As shown in FIG. On the other hand, the outer wall of the pipe is covered with the heat insulating material 33 to suppress the heat exchange with the outside air, and the water passing through the pipes 22, 26 by the insertion of the silicone rubber tube in the pipes 22, Even when the silicone rubber tube 24 is frozen, the silicone rubber tube 24 is temporarily shrunk to prevent the pipes 22 and 26 from being damaged. The pipe 22 made of a material having a good thermal conductivity is discharged from the heated header 12 or the heat storage tank Thereby allowing sufficient heat conduction to the pipes 22 and 26 to melt the iced water inside the pipe.
