Water-cooled battery

Abstract

A water-cooled battery include a battery body, Centrifugal pumps, water tanks, and cooling water pipes, the cooling water pipe is circumferentially fixed on the periphery of the battery main body, thecooling water pipe is provided with a water inlet and a water outlet, the water inlet is connected with the outlet of the centrifugal pump, The inlet of the centrifugal pump is connected with the bottom of the water storage tank, and the water outlet is connected with the top of the water storage tank. The cooling water pipe arranged in the invention can effectively reduce the temperature of theaccumulator, especially the high temperature brought by the accumulator when charging, thereby effectively protecting the accumulator and prolonging the service life of the accumulator.

Description

technical field [0001] The invention relates to the field of storage batteries, in particular to a water-cooled storage battery. Background technique [0002] Lead-acid batteries are rechargeable chemical power sources under the action of sulfuric acid and lead oxide. Especially during the charging process, the conversion of the active material of the positive and negative plates of the battery and the electrochemical reaction of electron gain and loss will cause the internal temperature of the battery to rise sharply. If the temperature rises above 80°C, if the temperature is not lowered in time, the internal parts of the battery will be carbonized, which will have a fatal impact on the performance of the battery. [0003] At present, the power supply unit adopts bath cooling and wind cooling when charging. [0004] Immersion cooling: immerse the power supply unit in the pool, add water from one side of the pool and discharge water from the other side, resulting in a wate...

AI Technical Summary

Problems solved by technology

[0004] Immersion cooling: immerse the power supply unit in the pool, add water from one side of the pool and discharge water from the other side, resulting in a water level difference, so that the water in the pool flows around the outside of the power box to cool it. This method has the possibility of cooling water seeping into the battery internally, causing battery electrolyte pollution, thereby affecting battery life

[0005] Air-cooled cooling: the fan is used to exhaust the heating power box, and the air flow is used to cool down. This method has a poor cooling effect and cannot reduce the temperature of the battery in time, and cannot effectively protect the battery.
