[0001] The utility model relates to the technical field of heat storage and heat exchange, and in particular to a heat storage and heat exchange device. Background Art
[0002] A heat storage and heat exchange device is a device used to store and transfer thermal energy. It is usually composed of a heat medium, a heat storage material, and a heat exchanger. The working principle of a heat storage and heat exchange device is to store excess thermal energy during off-peak hours or low loads, and release thermal energy during peak hours or high loads to achieve energy balance and improve utilization efficiency.
[0003] The heat exchange tubes inside the existing heat storage and heat exchange devices usually adopt a spiral design. However, with long-term use, some hot fluids carrying fine particles tend to slowly deposit inside the pipes and adhere to the pipe walls when passing through the heat exchange tubes, making them difficult to clean, thus gradually leading to blockage. Therefore, in response to the above problems, we have proposed a new type of heat storage and heat exchange device. Utility Model Content

[0006] Furthermore, a groove is provided on an inner wall of one side of the end cover, and a sealing ring is embedded in the groove.
[0007] Furthermore, a second mounting hole is formed through the outer surfaces of the two connecting plates near the middle, and a stainless steel inner tube is fixedly installed between the inner walls of the two second mounting holes.
[0008] Furthermore, heat exchange tubes are fixedly connected between the outer surfaces of the two connecting plates, and the gap between the heat exchange tubes and the heat exchange pipeline is filled with phase-changing lava material.
[0009] Furthermore, a fluid inlet pipe is symmetrically fixedly connected to a position near the left end of the outer surface of the stainless steel shell.
