Compact box-fin-type low-temperature heat-storage heat exchanger

The invention relates to a low-temperature heat-storage heat exchanger, in particular to a compact box-fin-type low-temperature heat-storage heat exchanger, and aims to solve the problems that an energy accumulator is large in size and difficult in improving heat exchange efficiency and is constrained by energy-storage material property, solar heat utilization has contradiction, cold/heat two-way utilization is unbalanced and operating strategy needs to be optimized in the aspects of system, equipment and method of an existing sleeve-type energy-storage multi-source heat pump integrated system. A sealing head is mounted on each of upper-portion two sides and lower-portion two sides of a heat exchange body, a flow equalizer is arranged in each sealing head, a refrigerant outlet pipe is connected with the sealing head on one side of the upper portion of the heat exchange body, a refrigerant inlet pipe is connected with the sealing head on the other side of the lower portion of the heat exchange body, a solar hot water outlet pipe is connected with the sealing head on the other side of the upper portion of the heat exchange body, a solar hot water inlet pipe is connected with the sealing head on one side of the lower portion of the heat exchange body, and the heat exchange body comprises multiple sets of heat exchange components which are mounted sequentially. The compact box-fin-type low-temperature heat-storage heat exchanger is used for low-temperature heat-storage heat exchange.
