Abstract: An energy storable air conditioning device includes a main body, at least one air blower module and at least one energy storage module. The main body has an air inlet, an air outlet and several receiving spaces connected to each other and disposed between the air inlet and the air outlet. The air blower module includes a first drawer inserted into one of the receiving spaces and a fan disposed in the first drawer. The energy storage module includes a second drawer inserted into another one of the receiving spaces and an energy storage unit disposed in the second drawer. The first drawer is connected to the second drawer.

Abstract: A flat evacuated-tube solar collector includes two parallel collecting tubes, a plurality of parallel evacuated tubes perpendicularly installed between two collecting tubes. Each evacuated tube includes two distal tube sections and a middle section situated between the two distal tube sections, and the middle section is in a flat shape, and has a cross-sectional area greater than that of the distal tube sections. The flat evacuated tubes substitute the conventional fins soldered onto a flat panel solar collector to receive sunlight, while the characteristic of two distal ends of the evacuated tube having a smaller cross-section than the middle section maintains an appropriate spacing between the collecting tube and a connecting point of the evacuated tube to assure the structural strength of the collecting tube.

Abstract: A non-welding solar collector tube connecting structure includes a collector tube having a tube wall, a containing space, a screw hole and a penetrating hole. The penetrating hole is interconnected to the containing space, and the connecting sleeve includes a tube pillar having a through hole, a plurality of screw threads formed on an external periphery of the tube pillar. A ring plate is installed at an end of the row tube, and the row tube is passed through the tube pillar, and a front end of the tube pillar is abutted against the ring plate, and the row tube is coupled to a side of the collector tube through tube pillar, and the ring plate is compressed by the tube pillar and abutted against the exterior of the penetrating hole.

Abstract: A multi-section heat-pipe solar collector includes a heat-exchanging pipe and at least one heat-collecting module. The heat-collecting module includes a heat pipe and a plurality of heat-collecting plates serially connected on one side of the heat pipe at intervals. One end of the heat pipe is inserted into the heat-exchanging pipe. The heat-collecting plates are arranged on the other end of the heat pipe in multiple sections and have different heat transfer characteristics respectively.

Abstract: A heat-pipe solar collector includes a heat-exchanging pipe, a sealing assembly and a heat pipe. The sealing assembly includes a connecting sleeve and a sealing ring. The connecting sleeve includes a pipe post through which the heat pipe is disposed. The sealing ring includes an annular sheath and an annular piece. The annular piece is pressed by the pipe post to abut the heat-exchanging pipe. One end of the heat pipe is disposed in the heat-exchanging pipe via the sealing assembly.

Abstract: The present invention is a solar heat collector having heat pipe. A heat exchanger has accommodating space and an opening recess. The opening recess has a screw thread and a though hole. The connecting barrel includes a pipe tube has a tunnel. The pipe tube is threadedly connected to the opening recess. An end of the heat pipe is inserted through the tunnel and the through hole and located in the accommodating space. Cool water following into the heat exchanger takes away the heat of the heat pipe. The heat exchange process of the heat pipe proceeds by the phase change of working fluid.
