The invention belongs to the technical field of heat exchange
energy storage, and particularly relates to a
solid-state multi-path heat exchange
energy storage device which comprises a shell, a second heat conduction
pipe body arranged in a spiral shape is arranged in the shell, a first heat conduction
pipe body is arranged on the inner side of the second heat conduction
pipe body, and a heat conduction sleeve is arranged on the inner wall of the first heat conduction pipe body in a sleeving mode. The
solid metal is better and faster in heat conduction effect, simple in structure and capable of producing, storing and releasing energy like liquid, the volume ratio caused by exchange is reduced, the exchange temperature can far exceed the boiling temperature of the liquid, the
lower limit value of the low temperature of heat exchange is lower, no liquid exists, and destructive power caused by freezing does not need to be considered. The heat exchange
energy storage device is simple in structure and not prone to volatilization and secondary
pollution, the problem of liquid leakage does not need to be considered in the carrying and transporting process, tedious protection devices and accessory equipment caused by
evaporation and lack do not need to be considered, cost caused by accessories is saved to the maximum extent, and the problem that an existing heat exchange energy storage device is prone to interference of the heat exchange effect due to temperature change is solved.
