Description

Technical Field

[0001] The utility model relates to the field of heat dissipation of energy storage batteries, and more specifically, to an air supply structure for heat dissipation of energy storage batteries. Background Art

[0002] Large energy storage systems are composed of container energy storage systems. Due to the system design of lithium-ion batteries themselves, the organic electrolyte used is flammable, and the system is prone to danger during operation. In the document with publication number CN217306624U, a wind supply structure for heat dissipation of container energy storage batteries is proposed. Cold air enters the wind supply structure from the air supply port of the wall-mounted air conditioner, and then blows toward the battery rack through the air guide interface. The heat emitted by several battery packs is pushed to the lower air environment by the flow wind to form hot return air, and is absorbed by the return air port to complete a heat dissipation cycle. The heat dissipation and air supply structure is designed according to the principle of high cold air density. When the above-mentioned air supply structure is in use, the cold air from the wall-mounted air conditioner is used to dissipate the heat of the energy storage battery. However, in actual use, the temperature difference between the inside of the container and the battery rack is large, resulting in water droplets on the battery rack, which will affect the normal use of the battery.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] (1) The utility model provides an air supply structure for heat dissipation of energy storage batteries. By means of the provided bent bars, metal tubes, three-hole inlet pipes and transport pipes, when the battery pack inside the refrigeration structure is cooled, the refrigerator is operated. After the wind passes through the refrigerator for cooling, the cold air is discharged into the inside of the side bars and the middle bar through the three-hole inlet pipes and the transport pipe. The cold air moves downward along the inside of the side bars and the middle bar. As the cold air moves downward, it is discharged into the inside of the connecting hole. When the cold air flows through the metal tubes, the cold energy is dissipated through the metal tubes, absorbing the heat inside the refrigeration structure. Water droplets are attached to the outer surface of the metal tubes. As the volume of the water droplets increases, the water droplets flow down along the outer surface of the metal tubes, and the water flows to the inside of the bent bars, where the water droplets are collected.

The air inside the refrigeration structure is ejected from the one-way valve through the installation pipe and the air pipe to cool the refrigerator. The thermal insulation plate will block the temperature on both sides of the interior of the placement box to avoid affecting the use of the refrigerator and the vacuum pump.
