Embodiment 1
[0035] Such as figure 2 , Figure 5 As shown, a medium-high temperature phase-change heat storage device includes a casing 1 , a liner 3 inside the casing 1 , a coil 5 and a base 7 below the casing 1 . The liner 3 is filled with a phase-change material 4, and there are multiple coils 5, all of which are arranged in a staggered manner. Each coil 5 includes a heat storage tube 51 and a main pipe 8 for welding water inlet or outlet. The connecting pipe 52 of the pipe 9 is integrally connected with the heat storage pipe 51 , and the heat storage pipe 51 is embedded in the phase change material 4 , and the heat storage pipes 51 have the same shape and are staggered with each other. In this embodiment, every two coils 5 form a group, and they are turned upside down to realize complementary spatial heat exchange, and enhance heat exchange density and heat exchange uniformity. The specific two arrangements are as follows image 3 , Figure 4 As shown, each group of coils 5 includes...
Embodiment 2
[0047] As shown in Figure 1(b), the connecting pipe 52 of the present embodiment includes an upward transition section 521, the position of the welding point 10 is higher than the first end, that is, the low point of the space, and the high point of the space is located in the inner tank, if the welding point 10 leaks , the heat transfer medium slides down the pipe to the lowest point in the space and drips.
[0048] All the other are identical with embodiment 1.
Embodiment 3
[0050] As shown in Figure 1(c), the connecting pipe 52 of this embodiment includes an upward transition section 521, the position of the welding point 10 is higher than the first end, that is, the low point of the space, and the high point of the space is located outside the inner tank, if the welding point 10 leaks , the heat transfer medium slides down the pipe to the lowest point in the space and drips.
[0051] All the other are identical with embodiment 1.
