Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of distribution box, especially relates to a condensate water automatic drainage device of liquid cooling energy storage cabinet. BACKGROUND

[0002] Liquid cooling energy storage technology uses liquid convection heat transfer to remove the heat generated by the battery, thereby reducing the battery temperature and improving the safety and efficiency of the energy storage system. However, the liquid cooling system generates condensate water during operation. If the condensate water is not discharged in time, it may cause a series of problems and may pose a threat to the safe and stable operation of the equipment. For example, the condensate water may accumulate on the partition plate between the battery Pack and the electrical compartment, causing damage to electrical components, a decrease in insulation performance, a decrease in equipment performance, and other safety hazards. At the same time, the condensate water may also corrode the metal components inside the equipment, shortening the service life of the equipment. Traditional condensate water treatment methods rely mainly on manual periodic cleaning or externally installed drainage devices. These methods not only increase maintenance costs but also may cause equipment damage or safety hazards due to improper operation.

[0003] The existing liquid cooling energy storage cabinet on the market mainly uses the following methods to prevent condensate water: adding a thermal insulation layer at the bottom of the battery PACK or using a PVC transparent hose for drainage. A small number of devices do not have a drainage and diversion structure and use holes at the bottom for drainage. However, these methods have the following problems: 1. Limited thermal insulation effect: Although adding a thermal insulation layer at the bottom of the battery PACK can reduce heat conduction to some extent, factors such as the thermal conductivity, thickness, and installation method of the thermal insulation material can affect its thermal insulation effect. In extreme working conditions, such as high humidity and low temperature environments, the thermal insulation layer may not be able to completely prevent the formation of condensate water. 2. Limited drainage efficiency: Although the PVC transparent hose can collect and drain condensate water, its drainage efficiency is affected by factors such as the diameter, length, and inclination angle of the hose. In cases where the amount of condensate water is large or the drainage path is long, the hose may not be able to drain the condensate water in time, causing water to accumulate inside the energy storage cabinet. 3. High maintenance cost: The PVC transparent hose needs to be regularly inspected and maintained to ensure that it is unobstructed. If the hose is blocked or damaged, it needs to be replaced or repaired in time, increasing the maintenance cost of the system. 4. Potential safety hazards: The PVC transparent hose may leak or break due to aging, wear and tear, etc. during long-term use, which may cause safety hazards. The hose connection parts may also leak due to loosening or poor sealing.

[0004] Therefore, the existing condensate water drainage device of the liquid cooling energy storage cabinet has many defects and shortcomings, and a more efficient, reliable, and automated drainage device needs to be developed to solve these problems. This new drainage device should have efficient drainage structure design, be simple and reliable, have low cost, and be maintenance-free, to ensure the safe and stable operation of the liquid cooling energy storage cabinet.
