Description

Technical Field

[0001] This invention relates to the field of cooling devices, and more particularly to a constant pressure water circulation cooling system for lead-acid batteries. Background Technology

[0002] During the activation process of internalized lead-acid batteries, a neutralization reaction occurs inside the battery, releasing a large amount of heat. Therefore, during the activation process of internalized lead-acid batteries, they are immersed in a water bath for cooling. The water temperature in the water bath rises relatively quickly, requiring water circulation. Moreover, the original water supply system consists of a main pipe that branches to each water bath, and the water bath has three layers (upper, middle, and lower). The water supply to each water bath varies greatly, with a larger water flow near the front end of the water supply. This temperature difference during the activation process leads to inconsistencies in battery performance. Summary of the Invention

[0003] The purpose of this invention is to provide a constant pressure water circulation cooling system for lead-acid batteries, which solves the technical problem that traditional cooling systems using a single main pipe to distribute water to each water tank are prone to uneven water distribution, resulting in large temperature differences in each water bath.

[0022] An air collecting ring is arranged around the outside of the tower body. The air collecting ring includes an annular horizontal base plate and an annular inclined air collecting plate. One end of the annular horizontal base plate is fixed to the outside of the tower body. The bottom of the annular inclined air collecting plate is connected to the other end of the annular horizontal base plate. The top of the annular inclined air collecting plate is inclined towards the tower body, and there is a gap between the top of the annular inclined air collecting plate and the surface of the tower body.

[0023] In one embodiment, the cooling tower further includes a baffle portion made of a high thermal conductivity metal material, the baffle portion comprising:

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] Please see Figure 1 This application provides a constant-pressure water circulation cooling system for the internal formation of lead-acid batteries, including multiple cooling water pumps 5, a hot water tank 2, a cooling tower 3, a cold water tank 4, and multiple water baths 1. Cooling water flows through the water baths 1, and the lead-acid batteries to be internally formed are located within the water baths 1. The input end of the hot water tank 2 is connected to the output end of the water bath 1 via an underground trench. The input end of the cooling tower 3 is connected to the output end of the hot water tank 2, and the cooling tower 3 is used to lower the temperature of the cooling water. The input end of the cold water tank 4 is connected to the output end of the cooling tower 3. The input end of the cooling water pumps 5 is connected to the cold water tank 4, and the output end of the cooling water pumps 5 is connected to the water baths 1, with each water bath 1 independently connected to a cooling water pump 5.

[0043] The lead-acid battery internal constant pressure water circulation cooling system provided in this embodiment first collects the cooling water that needs to be cooled in a hot water tank 2, and then the high-temperature cooling water in the hot water tank 2 is introduced into a cooling tower 3. The cooling tower 3 cools the cooling water, reducing the temperature of the high-temperature cooling water. The cooled water is then concentrated in a cold water tank 4 and pumped to each water bath 1 by a cooling water pump 5. Since each water bath 1 is connected to a separate cooling water pump 5, it is only necessary to control the power of each cooling water pump 5 to be consistent, thereby controlling the cooling water flow in each water bath 1 to be consistent, thus maintaining a basically consistent temperature in each water bath 1 and ensuring the consistency of the lead-acid battery activation process.

[0044] To remove impurities from the circulating cooling water, one embodiment includes a sedimentation tank 6, located between the hot water tank 2 and the cooling tower 3. Cooling water from the hot water tank 2 first flows into the sedimentation tank 6 for sedimentation before flowing into the cooling tower 3. By placing the sedimentation tank 6 next to the hot water tank 2, most impurities in the circulating cooling water are removed through the static sedimentation process, maintaining the water quality and preventing impurities from clogging the cooling system. Furthermore, because the cooling water temperature in the sedimentation tank 6 is higher, the solubility of calcium and magnesium ions in the cooling water decreases, causing them to form compounds (scale). This scale remains in the sedimentation tank 6, further reducing the calcium and magnesium ion content in the cooling water and optimizing the water quality.

[0045] Please see Figure 2 In one embodiment, the cooling tower 3 includes a tower body 31, a blower section 34, a cooling water outlet section 33, and a cooling water inlet section 32. The tower body 31 has a topless, cylindrical structure. Specifically, the tower body 31 can be made of a highly thermally conductive metal material, such as stainless steel or aluminum alloy. The cooling water inlet section 32 is located at the top of the tower body 31, with one end connected to a hot water tank 2, and is used to introduce cooling water to be cooled into the tower body 31. The cooling water outlet section 33 is located at the bottom of the tower body 31, with one end connected to the interior of the tower body 31 during cooling, and the other end connected to a cold water tank 4. The blower section 34 is located at the bottom of the tower body 31, with its outlet end connected to the interior of the tower body 31, and is used to introduce cold air into the tower body 31.

[0046] High-temperature cooling water is injected downward from the top of the tower body 31 through the cooling water inlet 32, and cold air is introduced upward from the bottom of the tower body 31 through the blower 34. This causes the cold air to collide with the high-temperature cooling water and exchange heat, thereby cooling the cooling water through the air. Then, the air carrying the heat in the cooling water is discharged from the top of the tower, and the cooled water is drawn out from the bottom of the tower body 31 through the cooling water outlet 33 and enters the cold water pool 4.

[0047] Please see Figure 2 In order to improve the uniformity of interaction between cooling water and cold air during the descent process.

[0048] In one embodiment, the cooling water inlet 32 ​​includes a rain distribution plate 322 and a first pump body 321. The first pump body 321 is fixed to the top of the tower body 31, and its inlet is connected to the hot water tank 2 via a pipe. The rain distribution plate 322 is disposed on the inner top of the tower body 31, and has a cavity inside. A plurality of water outlet holes are evenly distributed at the bottom of the cavity. The rain distribution plate 322 is connected to the outlet of the first pump body 321 via a pipe.

[0049] By setting up the rain distribution plate 322, the cooling water entering the rain distribution plate 322 is evenly discharged through the water outlet on the rain distribution plate 322, forming a uniform rain curtain to fully disperse the cooling water, so as to facilitate sufficient interaction between the cooling water and the cold air, and improve the uniformity of interaction between the cooling water and the cold air during the descent process.

[0050] Please see Figure 2 To improve the cooling effect of the cooling tower 3, in one embodiment, the blower section 34 includes an air collecting ring 343, a U-shaped duct 342, and a fan 341. The fan 341 is fixed to the outside of the tower body 31. One end of the U-shaped duct 342 is connected to the output end of the fan 341, and the other end of the U-shaped duct 342 extends through the bottom of the tower body 31 and into the tower body 31. The air collecting ring 343 is arranged around the outside of the tower body 31. The air collecting ring 343 includes an annular horizontal base plate 3431 and an annular inclined air collecting plate 3432. One end of the annular horizontal base plate 3431 is fixed to the outside of the tower body 31, and the bottom of the annular inclined air collecting plate 3432 is connected to the other end of the annular horizontal base plate 3431. The top end of the annular inclined air collecting plate 3432 is inclined towards the tower body 31, and there is a gap between the top end of the annular inclined air collecting plate 3432 and the surface of the tower body 31.

[0051] Because the tower body 31 is made of a metal material with high thermal conductivity, when the fan 341 operates and supplies air into the tower body 31, the input end of the fan 341 will continuously draw air into the air collecting ring 343, resulting in negative pressure inside the air collecting ring 343. This causes the air near the tower body 31 to be quickly drawn into the air collecting ring 343 through the gap between the annular inclined air collecting plate 3432 and the tower body 31, thereby accelerating the air circulation outside the tower body 31, improving the heat dissipation performance of the tower body 31 (which is made of a metal material with high thermal conductivity), reducing the temperature of the tower body 31, and allowing the heat inside the tower body 31 (heat from the high-temperature cooling water) to dissipate more quickly, thus improving the cooling effect of the cooling tower 3.

[0052] Please see Figure 2 Because the cooling water falls directly down quickly, the contact time between the cooling water and the cold air is short, resulting in a short cooling time.

[0053] To improve the cooling time of the cooling water, in one embodiment, the cooling tower 3 further includes a baffle portion 35, which is made of a high thermal conductivity metal material. The baffle portion 35 includes an air guide pipe 353, a second inclined baffle 352, and a first inclined baffle 351. The first inclined baffle 351 is disposed inside the tower body 31, with gaps between its upper and lower ends and the inner wall of the tower body 31. The second inclined baffle 352 is disposed inside the tower body 31, located below the first inclined baffle 351. The inclination direction of the second inclined baffle 352 is opposite to that of the first inclined baffle 351. The top of the second inclined baffle 352 is connected to the inner wall of the tower body 31, and a gap exists between its bottom and the inner wall of the tower body 31. The bottom of the air guide pipe 353 extends through the top of the second inclined baffle 352, and the other end of the air guide pipe 353 extends into the lower side of the first inclined baffle 351.

[0054] When the cooling tower 3 is working, the cold air introduced by the blower 34 first enters the tower from the bottom of the tower body 31, then moves upward along the lower surface of the second inclined baffle 352, and then enters the lower surface of the first inclined baffle 351 through the air guide pipe 353 and moves upward. It then flows out from the gap between the top of the first inclined baffle 351 and the inner wall of the tower body 31, until it is discharged from the top of the tower (during this process, cooling water flows through the gap between the bottom of the first and second inclined baffles 351 and the tower body 31, making it difficult for the cold air to flow upward from that position). This allows the cold air to fully cool the first and second inclined baffles 351 and 352.

[0055] The high-temperature cooling water enters from the top of the tower through the cooling water inlet 32, first falling onto the upper surface of the first inclined baffle 351, and then moving downwards along the upper surface of the first inclined baffle 351 until it falls through the gap at the bottom onto the upper surface of the second inclined baffle 352. It then flows downwards along the upper surface of the second inclined baffle 352 until it reaches the bottom of the tower body 31. During this process, the cold air effectively cools the first inclined baffle 351 and the second inclined baffle 352. Since the first inclined baffle 351 and the second inclined baffle 352 are made of high thermal conductivity metal materials (such as stainless steel, aluminum alloy, etc., and can be made into thin plates), the heat from the cooling water on the upper surface of the baffles can be quickly transferred through the baffles to the cold air on the lower surface, and carried away by the cold air, thus achieving the cooling water cooling treatment. Furthermore, since the baffle can impede the speed at which the cooling water falls, the cooling time of the cooling water is greatly increased, thereby improving the cooling time of the cooling water and enhancing the cooling effect of the cooling tower 3.

[0056] In one embodiment, the top of the air duct 353 is configured as a flat structure. By configuring the air duct 353 as flat, the cold air flowing out through the air duct 353 can be spread evenly on the lower surface of the first inclined baffle 351, allowing the cold air to spread better along the lower surface of the first inclined baffle 351, thereby making the cold air absorb heat from the first inclined baffle 351 more effectively.

[0057] In one embodiment, the baffle portion 35 further includes a guide plate 354, which is disposed on the inner side of the tower body 31 at the top of the first inclined baffle 351. The inclination direction of the guide plate 354 is opposite to that of the first inclined baffle 351. First, the guide plate 354 allows cold air to flow upward towards the uniform distribution section within the cooling water inlet 32 ​​after being discharged from the top of the first inclined baffle 351, further counteracting the cooling water and enhancing the cooling effect of the cold air on the cooling water. Second, the guide plate 354 prevents cooling water from flowing down through the gap between the top of the first inclined baffle 351 and the inner wall of the tower body 31, thereby preventing the cooling water from obstructing the upward discharge of cold air from that position.

[0058] Please see Figure 3 In one embodiment, both the first inclined baffle 351 and the second inclined baffle 352 have continuously concave pit structures 3511 on their surfaces. The pit structures 3511 slow down the flow rate of cooling water on the upper surface of the baffles, increasing the time the cooling water stays on the first inclined baffle 351 and the second inclined baffle 352, thus improving the cooling time. Furthermore, the pit structures 3511 increase the contact area between the cooling water baffles and between the cold air and the baffles, thereby improving heat conduction efficiency and allowing heat in the cooling water to be transferred more quickly to the cold air on the other side. This, in turn, improves the cooling effect of the cooling tower 3.

[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
