Embodiment 1
[0042] The heat storage body is a phase-change heat storage material filled in a glass inner tube, which absorbs and releases heat through physical state changes. Both the water inlet pipe and the water outlet pipe are arranged in the header one 11. The two ends of the heat exchange tube are straight parts, and there is a spiral bending part between the two straight parts, which increases the length of the heat exchange path and realizes sufficient heat exchange. The inlet end of the heat collection tube is provided with a sealing plug, and the sealing plug is provided with a matching straight part. There are two through holes in the shape part, the spiral bending part of the heat exchange tube is built into the glass inner tube, the straight part of the heat exchange tube is pierced with a sealing plug through hole, and one end of the straight part of the heat exchange tube is connected to the water inlet pipe. As the water inlet end, the straight part at the other end of the...
Embodiment 2
[0047] The heat storage body is arranged in the base 2, and the heat storage body is composed of several heat storage rods. The heat storage rod includes a rod body and a phase-change heat storage material. The heat exchange tube and the heat transfer tube. The heat collection tube has an inlet and an outlet for the heat transfer medium to enter and exit. The heat rod forms a circulation loop, and the heat transfer medium is steam or water. After the heat collection tube 6 converts solar energy into heat energy, the heat transfer medium is heated. After the heat transfer medium passes through the heat transfer tube and the heat storage rod, the phase change heat storage material absorbs the heat transfer medium. The temperature, that is, thermal energy is stored in the heat storage rod. When the user end uses water, the heat energy in the phase change heat storage material is used to heat the cold water through the heat exchange tube and the heat storage rod to realize heat ex...
