Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery technology, specifically to a lead-acid battery with good heat dissipation. Background Technology

[0002] In existing technologies, multiple sets of lead-acid batteries are typically installed in a single battery casing. For example, in electric vehicles, multiple sets of lead-acid batteries are installed inside the battery casing and then connected in series.

[0003] However, lead-acid batteries installed inside a sealed casing have poor heat dissipation, and heat accumulates inside the battery casing and is difficult to dissipate. Some users drill holes in the casing to create cooling ducts when the electric vehicle is in motion. However, when it rains, rainwater can easily enter the battery casing through the drilled holes, which can easily cause short circuits.

[0004] Therefore, we propose a lead-acid battery with good heat dissipation. Utility Model Content

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This embodiment is a lead-acid battery with good heat dissipation.

A cover plate 2 is fixedly installed on the upper outer surface of the battery housing 1. Terminal blocks 3 are installed on the left and right ends of the upper outer surface of the cover plate 2. A cooling structure 4 is fixedly installed on one outer surface of the battery housing 1. The cooling structure 4 includes a protective cover 14, an exhaust fan 15, an air inlet 16, and a filter screen 17. The protective cover 14 is equipped with a heat-conducting plate 5, a water pump 6, an inlet pipe 7, and heat dissipation fins 8. A cavity 12 is opened inside the heat-conducting plate 5. One end of the water pump 6 is fixedly connected to a liquid extraction pipe 11. The water pump 6 is fixedly installed in the middle of the right outer surface of the heat-conducting plate 5. A return pipe 13 is fixedly installed in the middle of the left outer surface of the heat-conducting plate 5. A heat-conducting pipe 10 is installed on the outer wall of the lead-acid battery unit 9.

[0026] The liquid inlet pipe 7 is fixedly installed between the outer surface of the other end of the water pump 6 and one end of the heat-conducting pipe 10; one end of the liquid extraction pipe 11 extends into the right side of the cavity 12, and one end of the return pipe 13 extends into the left side of the cavity 12, and one end of the return pipe 13 is connected to the other end of the heat-conducting pipe 10; the heat-conducting plate 5 is fixedly installed on one side of the outer surface of the battery casing 1, and the heat dissipation fins 8 are fixedly installed on one side of the outer surface of the heat-conducting plate 5; the material of the heat-conducting pipe 10 is pure copper, and the materials of the heat dissipation fins 8 and the heat-conducting plate 5 are aluminum alloy; the air inlet 16 is opened on the outer surface of the left end of the protective cover 14, the filter screen 17 is fixedly installed in the air inlet 16, and the exhaust fan 15 is fixedly installed on the outer surface of the right end of the protective cover 14.

[0027] It should be noted that this utility model is a lead-acid battery with good heat dissipation. The battery casing 1, cover plate 2, terminal block 3, and lead-acid battery unit 9 described herein are all prior art. The lead-acid battery unit 9 is connected in series inside the battery casing 1, which is readily known to those skilled in the art and will not be elaborated further. The coolant is an aqueous solution of ethylene glycol, which has the advantages of good thermal conductivity and high chemical stability. The heat pipe 10 is made of pure copper, and the heat plate 5 and heat dissipation fins 8 are both made of aluminum alloy, which has good thermal conductivity. The coolant fills the space between the heat pipe 10 and the heat plate 5. Inside the battery, the operation of the water pump 6 drives the circulation of coolant. The coolant absorbs heat on the outer wall of the lead-acid battery unit 9 and then cools down at the heat conduction plate 5. The heat dissipation fins 8 increase the heat dissipation area. The cooling structure 4, through the operation of the exhaust fan 15, blows fresh air from outside through the air inlet 16 onto the heat dissipation fins 8, increasing the airflow speed and improving the cooling efficiency, thus cooling the coolant. The cooled coolant then re-enters the interior of the heat conduction pipe 10 to absorb heat and cool the lead-acid battery unit 9. The heat conduction pipe 10 is wrapped around the outer wall of the lead-acid battery unit 9.
