Description

Technical Field

[0001] The utility model belongs to the technical field of storage batteries, and in particular relates to a formation tank with enhanced heat dissipation effect. Background Art

[0002] Lead-acid batteries are widely used in industries such as industry and transportation. Lead-acid batteries for low-speed electric vehicles (EVF batteries) are a type of lead-acid batteries. Lead-acid batteries need to be formed during the production process. The battery formation process is an important process in the production process of lead-acid batteries. Because the battery formation process generates heat, in order to ensure battery performance, the electrolyte temperature during the formation process needs to be controlled and the formation is carried out in a dedicated formation tank array.

[0003] The patent document with the announcement number CN 218602520 U discloses a formation tank in a storage battery, including a box structure with an open top, the box structure including a panel and a bottom plate connected to the bottom of the panel, the panel on at least one side is connected to the bottom plate in a detachable manner, and the battery inlet and outlet are formed after the panel is removed, an overflow trough is provided inside the box structure, a drainage hole is provided in the overflow trough, the height from the overflow port of the overflow trough to the bottom plate is less than the height of the panel, a water inlet hole is provided on the bottom plate of the box structure, and the water inlet hole and the overflow trough are respectively arranged at two opposite ends of the box structure. Cooling water enters the tank array through the water inlet at the bottom of the formation tank array, and then flows out through the overflow hole above the tank array. During the flow of the cooling water, heat is transferred between the battery shell and the electrolyte inside the battery, and the heat generated by the formation process is taken away.

[0004] However, the casing of lead-acid batteries (EVF batteries) for low-speed electric vehicles is ABS plastic, which has an extremely low thermal conductivity of about 0.02W / (m·K)-0.046W / (m·K), resulting in a limited amount of heat that can be taken away by the cooling water during the circulation process. In addition, the intensity of the reactions in different parts of the battery varies. The temperature of the upper part of the battery is higher than that of the lower part, resulting in a lower circulating water temperature closer to the bottom of the tank and a higher circulating water temperature closer to the water surface. The temperature of the upper part of the battery is high, and the water temperature is also high, which makes it impossible to take away the heat in time. During the battery formation process, the electrolyte temperature often exceeds the process standard, affecting the battery performance. Summary of the invention

[0005] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art, thereby providing a formation tank with enhanced heat dissipation effect, increasing the upper and lower circulation inside the tank array, reducing the temperature difference of the upper and lower circulation water, and adding air cooling on the basis of water cooling, thereby improving the heat dissipation effect, controlling the electrolyte temperature, and ensuring the battery formation performance.

[0006] The technical solution of the utility model is: a forming tank with enhanced heat dissipation effect, comprising a forming tank body;

[0007] The chemical formation tank body is an open groove with an upper end opened and surrounded by two long side walls, two short side walls and a bottom wall. The middle of the chemical formation tank body is divided into two symmetrical groove rows by a middle partition.

[0008] A horizontal drainage pipe extending along the length direction of the trough array is installed inside the trough array, one end of the drainage pipe is closed and the other end is connected to a drainage pump arranged at the bottom of the trough array, and a plurality of drainage holes are evenly distributed on the drainage pipe;

[0009] There are several cover plates above the trough array, and the cover plates are evenly arranged along the length direction of the formation trough body. There are sealing plates between the outer sides of the cover plates at both ends and the trough array. There are openings on both ends, one of which is connected to an air inlet duct, and the other opening is connected to an exhaust duct.

[0010] The middle partition is higher than the side wall height of the formation tank body, and the cover plate covers the middle partition and the top of the long side wall of the tank row.

[0011] One end of the cover plate is hinged to the middle partition plate through a hinge.

[0012] The drainage pipe is installed on the middle partition plate, and the drainage hole faces the middle of the groove row.

[0013] Multiple overflow hole groups are hollowed out on the two long side walls. The multiple overflow hole groups are located at the same height and are evenly distributed side by side along the length direction of the long side walls. Each overflow hole group is composed of multiple overflow holes arranged side by side, and an overflow groove is provided outside each overflow hole group.

[0014] The height of the drain hole on the drain pipe is consistent with the height of the overflow hole.

[0015] The two long side walls, the two short side walls, the middle partition and the bottom wall are made of black flame-retardant PP material with a thickness of 20 mm.

[0016] The cover plate is made of transparent flame-retardant PP material, has a thickness of 20 mm, and is wrapped with sealing strips on the four sides.

[0017] The drainage pipe is a PP pipe with a diameter of Ø50mm.

[0018] A circulation pump is added to the tank array. The circulation pump draws the circulating water with a lower temperature from the bottom of the tank array and then sprays it from the top of the tank array, reducing the temperature difference of the circulating water in the upper and lower parts of the tank array and improving the cooling effect. In addition, the top of the formation tank array is closed, and cold air is introduced from one side of the short side of the tank array, and the other side is ventilated. Through air circulation, the heat of the upper circulating water in the tank array and the heat of the upper part of the battery are taken away in time. That is, air cooling is added on the basis of water cooling to improve the heat dissipation effect, control the electrolyte temperature, and ensure battery performance.
