Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of power equipment heat management, specifically relates to a box type energy storage equipment. BACKGROUND

[0002] The cascading container is an integrated power distribution and control solution, which usually includes transformers, switch cabinets, control cabinets, contactors and reactors and other key components, which are concentrated in a mobile container unit for rapid deployment, transportation and installation. Its main role is to quickly deploy the power system at the place where the power equipment is needed, such as the construction site, temporary facilities or activity site. In order to ensure the stable operation of the core components inside the container, the container product needs to be designed for heat dissipation. Forced air cooling is a common method for cooling high-power density electronic equipment, and its principle is: using cold and hot air interaction to control the temperature rise of electronic equipment to achieve heat dissipation effect. Since the container is operated in the external environment for a long time, in order to ensure the normal operation of the container in harsh environments (strong wind, heavy rain, humidity, etc.), the container needs to be sealed with high protection level design, so the container uses air conditioning for air circulation. Under this working condition, when the air flow passes through the corner of the cascading container, it will collide with the vertical wall, and vortex area (i.e. air flow dead zone) and significant kinetic energy loss will be generated in these corners. The vortex area will hinder the smooth flow of air flow, which will affect the temperature and humidity control inside the container, and will have adverse effects on the transformers, switch cabinets, control cabinets, contactors and reactors inside the container. Secondly, the flow of air in the vortex area becomes slow or even stagnant, which requires additional power to overcome this resistance. Therefore, when using fans, air conditioners and other equipment to ventilate or control the temperature of the container, the energy consumption will be significantly increased.

[0003] Therefore, a new method is needed to effectively solve the heat dissipation problem in the container, which has higher heat dissipation efficiency, cost effectiveness and easy implementation characteristics while maintaining the original working condition and structure. SUMMARY
