The invention discloses a cold and heat
source separation type heat conduction fin based on
topological optimization, a design method and a
sensible heat storage unit, and belongs to the technical field of
heat energy storage. In order to solve the problems that an existing heat storage fin is low in
heat transfer efficiency and cannot achieve charging, discharging and decoupling, the fin structure is provided and provided with a heat source channel matching part and a
heat sink channel matching part which are spatially isolated, and a fin body is of a non-uniform multi-stage branched topological structure extending outwards from a channel area. The structure is generated based on a
topological optimization algorithm applying manufacturing constraints, and
physical separation of the heat charging process and the heat discharging process is achieved while the
casting process requirement is met. The effective heat
conductivity coefficient and the heat charging and discharging rate are remarkably improved, heat charging and discharging are carried out at the same time, and the operation flexibility of the heat storage
system is greatly improved.
