Description

Technical Field

[0001] This invention pertains to small-scale temperature-controlled intelligent fire prevention equipment, specifically relating to a battery water-cooling and heating intelligent fire prevention device. Background Technology

[0002] New energy vehicles, electric bicycles, and energy storage stations all rely on batteries for charging, energy storage, and propulsion. Common battery types include lead-acid batteries and lithium batteries (including lithium-ion and lithium polymer batteries). Different types of batteries have different charging requirements, such as battery power, suitable temperature, heat dissipation conditions, and safety factors. Existing battery charging methods involve multiple batteries connected in parallel for uninterrupted charging, and these are all closed and fixed without air cooling or ordinary liquid cooling devices.

[0003] In winter, the electrolyte viscosity of batteries increases at low temperatures, the migration speed of the positive and negative electrodes slows down, resulting in increased internal resistance. During low-temperature charging, some energy is used to preheat the battery instead of driving. At 0 degrees Celsius in winter, the battery capacity decreases by 20%-30%, and at -10 degrees Celsius, the battery capacity decreases by 50%-60%, resulting in a reduction in the driving range of electric vehicles.

[0004] During summer charging, heat can accumulate rapidly between batteries, potentially rising to 30-50 degrees Celsius. This can cause localized high temperatures, triggering a chemical overheating reaction within the battery and releasing a large amount of heat and flammable gases, leading to a fire or explosion. Summary of the Invention

[0005] The parent patent application was filed on October 24, 2024, application number 2024114935535. The technical problem to be solved by this divisional invention is to address the technical defects of the parent patent. The water tank cover is provided with a digital display temperature control cable inlet leading to a water level monitoring heating rod installed inside the water tank. In winter, when the water temperature is below 15 degrees, the digital display temperature controller automatically starts the water level monitoring heating rod to heat the water to a constant temperature of 25 degrees. In summer, by sharing the digital display temperature control data and switching between hot and cold water, the water level monitoring heating rod goes into hibernation and stops heating when the water temperature exceeds 15 degrees. When the water temperature exceeds 25 degrees, it maintains a constant water temperature of 15-25 degrees through water cooling circulation.

[0006] The present invention provides a battery water cooling and heating intelligent fire prevention device, which includes a water tank, reinforcing ribs, a water level monitoring heating rod, a smoke alarm sensor, a water pump, a water tank cover, a water suction pipe, a water inlet, a water suction outlet, a reserved hole for a battery waterproof heat dissipation box, a digital display temperature control cable inlet, a battery waterproof heat dissipation box, and a battery waterproof heat dissipation slot.

[0007] Further improvements include

[0008] This invention relates to an intelligent fireproof battery water-cooling and heating device, comprising a water tank, a water level monitoring heating rod, a digital display temperature controller, a smoke alarm sensor, a water pump, and a waterproof battery cooling box. These are key components of the invention. The water tank, its inner bottom plate, the reinforcing ribs around the tank, and the water tank cover are made of polyethylene injection molding to prevent tank deformation and stabilize the waterproof battery cooling box. The waterproof battery cooling box and its internal battery cooling slots are formed by aluminum plate molding. The battery is placed inside the waterproof battery cooling box, and then 5 / 6 of it is placed into the water tank through a pre-drilled hole in the waterproof battery cooling box on the water tank cover. A 1cm-3cm gap is maintained between the waterproof battery cooling boxes according to user requirements. In winter, when the water temperature is below 15 degrees Celsius, the water level monitoring heating rod is automatically activated by the digital display temperature controller to heat the water to a constant temperature of 25 degrees Celsius. Fires caused by electric vehicles usually occur while charging or driving, when the battery is aging, overheating, and emitting smoke, and no one notices or fire extinguishing facilities are available, resulting in irreparable losses. This invention uses a smoke alarm sensor installed on the outer shell of the water tank to monitor in real time, detect fires immediately, and automatically activate the water pump to fill the waterproof heat dissipation box of the battery with water to cool the battery and shut off the engine. As long as the source of the fire is detected in time, a bowl of water can eliminate the fire hazard. The constant water temperature of 15-25 degrees Celsius can extend the battery's lifespan and reduce the risk of fire by more than 90%.

[0009] This invention relates to a novel and inventive intelligent fire prevention device for battery water cooling and heating. Utilizing water principles, water circulation, and hot / cold switching, the heating element is activated to heat the water when the water temperature is below 15 degrees Celsius in winter, and shuts down when the water temperature is above 15 degrees Celsius in summer. The water temperature is maintained at a constant 25 degrees Celsius through water cooling circulation. The device has a simple and reasonable design, is easy to install and maintain, and can be mass-produced to meet market demands.

[0022] See Figures 1 to 5 (Mother's Case) Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 (Sub-case) The present invention provides a battery water cooling and heating intelligent fireproof device, which includes a water tank 1, a water level detection heating rod 5 and an inner bottom plate and reinforcing ribs 2 around the water tank, a smoke alarm sensor 3 and a water pump 4 on the outer shell of the water tank 1, a water tank cover 6 on the upper part of the water tank 1, a water inlet 7 and a water outlet 8 and a digital display temperature control cable inlet 10 on the water tank cover 6, and a battery fireproof heat dissipation box 12 containing a battery 14 heat dissipation slot 13, a smoke alarm sensor 3, a water pump 4, and a water level detection heating rod 5, which are powered by the battery 14.

[0023] Working principle of the intelligent fire prevention device for battery water cooling and heating in this invention:

[0024] The battery water cooling and heating intelligent fireproof device includes a water tank 1 with a water level detection heating rod 5 inside, an inner bottom plate, and reinforcing ribs 2 around it to prevent deformation of the water tank 1 and to stabilize the battery waterproof heat dissipation box 12. The battery 14 is installed in the battery waterproof heat dissipation box 12, and then through the water tank cover plate 6, the battery waterproof heat dissipation box 5 / 6 is placed into the water tank 1 through the reserved hole 11. The battery waterproof heat dissipation box 12 is directly separated from the battery waterproof heat dissipation box 12 with a gap of 1cm-3cm according to the user's needs. If the water temperature is below 15 degrees in winter, the water level detection heating rod 5 in the water tank 1 will automatically start to heat the water to a constant water temperature of 25 degrees. If the water temperature is above 15 degrees in summer, the heating rod 5 will go into hibernation and stop heating. If the water temperature exceeds 25 degrees, the water cooling circulation will maintain a constant water temperature of 15-25 degrees through the digital temperature control data.

[0025] Fires involving electric bicycles typically occur when the battery (14) ages during charging or driving, overheating and emitting smoke without open flame. This often goes unnoticed or when fire extinguishing equipment is unavailable, leading to irreparable damage. This invention addresses this by using a smoke alarm sensor (3) installed on the outer shell of the water tank (1) to monitor the fire in real time. It automatically activates the water pump (4) to fill the waterproof cooling box (12) of the battery with water, cooling down the battery (14) and extinguishing the fire. This allows for immediate detection of the fire source; in fact, just a bowl of water can eliminate the fire hazard. The set constant water temperature of 15-25 degrees Celsius extends battery life and reduces the fire risk by over 90%. The invention's design is simple, reasonable, easy to install and maintain, and can be mass-produced to meet market demand.
