AI Technical Summary

Technical Problem

In energy storage devices, the temperature of the energy storage battery is too high or the humidity of the energy storage cabinet is too high, which affects the normal operation of the equipment. The prior art requires the installation of two independent heat exchangers for heat dissipation and dehumidification, resulting in complex systems, large number of parts and difficult installation.

Method used

By providing a partition in the heat exchanger, it is divided into two heat exchange parts, forming a refrigeration module and a dehumidification module of the energy storage battery, double refrigeration of the temperature and ambient humidity of the energy storage battery are realized.

Benefits of technology

The dual cooling of energy storage battery temperature and ambient humidity is achieved through a single heat exchange component, simplifying the installation process, saving installation space and cost, and improving manufacturing efficiency.

Abstract

A heat exchange apparatus and an energy storage apparatus, relating to the technical field of cooling and dehumidification devices. The heat exchange apparatus is used for being arranged in an energy storage apparatus, and comprises a heat exchanger and a partition member. The heat exchanger is internally provided with a refrigerant channel; the partition member is located in the heat exchanger; the partition member divides the heat exchanger into a first heat exchange portion and a second heat exchange portion, and divides the refrigerant channel into a first refrigerant channel and a second refrigerant channel; the first heat exchange portion is used for dissipating heat from an energy storage battery; the second heat exchange portion is located outside the energy storage battery and used for reducing the air humidity in an energy storage cabinet; and the first refrigerant channel is separately communicated with a first refrigerant inlet pipe and a first refrigerant output pipe, and the second refrigerant channel is separately communicated with a second refrigerant inlet pipe and a second refrigerant outlet pipe. In the present application, the heat exchanger is divided into two heat exchange portions by means of the partition member so as to form a cooling module for the energy storage battery and a dehumidification module for the energy storage battery, respectively, such that dual cooling of the temperature of the energy storage battery and the humidity of the environment in which the energy storage battery is located can be realized by means of a single heat exchange component.
