Description

Lead-acid storage battery with single-lattice heat dissipation structure

Technical Field

Background

Compared with other storage batteries, the lead-acid storage battery has the advantages of low price, low manufacturing cost and high active safety, so that the lead-acid storage battery is widely applied to various fields. In the field of energy storage, the lead-carbon energy storage battery has the characteristics of long cycle life, strong charge acceptance and the like. The general 2V type energy storage battery is a hexahedral cuboid, and when the battery is charged, heat generated by charging is mainly dissipated through a battery shell in contact with a plate surface in a plate group.

However, in order to increase the energy density of the battery and reduce the production cost, the energy storage battery of 4V or more has an integral structure. When the battery adopting the structure is in a large charging current, the heat productivity of the pole group is increased due to large-current charging, the internal temperature of the pole group is increased, the heat accumulated in the pole group of the middle single lattice cannot be timely dissipated due to insufficient heat dissipation surfaces, the high temperature caused by heat accumulation causes irreversible damage to the positive pole plate and the resin shell, and the service life of the battery is shortened. In addition, the heating caused by continuous large-current charging may cause the performance difference between the battery cells to be aggravated, the middle cell causes the oxygen evolution potential of the middle cell to be reduced due to high temperature caused by charging under the same current condition, the water loss is increased compared with the adjacent cells, and finally the service life of the cell is reached in advance. In order to avoid high heat generation in the electrode group, the charging is generally performed with a current of about 0.12C. However, this method limits the performance of the charging performance of the battery, and is fatal to the energy storage battery with a fast charging requirement.

The invention solves the problem of poor heat dissipation effect of the existing lead-acid storage battery by simultaneously arranging the box body, the through hole, the heat dissipation copper plate, the hollow copper pipe, the water cooling pipe, the fan blade, the heat dissipation silica gel and other components.

This scheme has set up and has contained multiple heat dissipation measures such as copper pipe heat dissipation, water-cooling heat dissipation, fan blade forced air cooling heat dissipation, heat conduction silica gel heat dissipation, can play better radiating effect theoretically. However, the scheme does not solve the problem of how to better radiate the single-cell battery, and the adjacent batteries are tightly attached together, so that the radiation is difficult even if the radiation means is increased; the scheme has set up multiple conventional heat dissipation method, however it not only is inconvenient to use, and it also can be problematic to mutually support improperly, if when lacking flowing water and can't realize the water-cooling, the heat is gathered at the copper pipe in a large number, causes local overheat, can damage the battery and even causes the accident.
