It can monitor the temperature, smoke, and flame conditions inside the power battery pack in real time and issue an alarm promptly in case of any abnormality, allowing relevant personnel to take timely countermeasures. However, when faced with a battery pack fire, this device can only issue an alarm.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0019] like Figures 3-8 As shown, an energy-saving automotive thermal management device includes a vehicle body 1, a battery pack 2, and battery blocks 3; the battery pack 2 is installed on the vehicle body 1; and a plurality of battery blocks 3 are installed inside the battery pack 2. It also includes a heat exchange assembly, fins 4, a first liquid inlet pipe 5, a first nozzle 6, a second liquid inlet pipe 7, a second nozzle 8, and a liquid distribution system; the heat exchange assembly is installed on the vehicle body 1; several fins 4 are provided on the outer side of each battery block 3; each fin 4 is made of a high thermal conductivity material; based on the view from the middle of each battery block 3 outwards, each fin 4 is gradually inclined downwards; several fins 4 between each two adjacent battery blocks 3 are staggered; several first liquid inlet pipes 5 are provided in the middle of the heat exchange assembly; each first liquid inlet pipe 5 is located between four adjacent battery blocks 3; each first liquid inlet pipe 5 is connected to a first nozzle 6; each first liquid inlet pipe 7, second nozzle 8, and liquid distribution system; Each nozzle 6 has several first spray holes 6002 arranged in a ring; each first nozzle 6 has several first hot melt adhesive 6001; a second liquid inlet pipe 7 is provided at the front and rear of the heat exchange assembly; each second liquid inlet pipe 7 is located between two adjacent battery blocks 3; each second liquid inlet pipe 7 is connected to a second nozzle 8; each second nozzle 8 has several second spray holes 8002 arranged symmetrically on both sides; each second nozzle 8 has several second hot melt adhesive 8001; when the vehicle is driving normally, the coolant flowing inside the heat exchange assembly passes under the battery block 3. Heat exchange and cooling are performed on battery block 3 to prevent it from overheating and overloading during vehicle operation. During cooling, fins 4 made of high thermal conductivity guide the temperature of battery block 3, directing the heat from the center to the outside, enhancing heat dissipation and extending its lifespan. When the vehicle chassis is damaged, causing coolant leakage from the heat exchange assembly, the fins 4, which are gradually tilted downwards and staggered, block the leaking coolant, preventing it from spraying onto battery block 3, as the terminals of battery block 3 are located on its upper side. The upper wiring terminal prevents the battery block 3 from short-circuiting and becoming unusable, saving vehicle maintenance costs. When the battery block 3 catches fire, because the battery pack 2 is in a closed state, heat conduction is fast. The heat conducted through the heat source melts the first hot melt adhesive 6001 on the first nozzle 6 and the second hot melt adhesive 8001 on the second nozzle 8, thereby causing the coolant in the heat exchange assembly to be sprayed out towards the upper side of the battery block 3 through the first spray hole 6002 and the second spray hole 8002 to extinguish the fire and prevent the fire from growing and causing the battery block 3 to explode, thus avoiding serious damage to the vehicle and further saving vehicle maintenance costs.

[0020] The heat exchange assembly includes a liquid storage tank 101, a pump 102, a heat exchange frame 103, and transfer pipes 104. The liquid storage tank 101 is located at the front of the vehicle body 1. A pump 102 is fixedly connected to both the left and right sides of the liquid storage tank 101. A heat exchange frame 103 is fixedly connected to the lower inner side of the battery pack 2. The heat exchange frame 103 has a hollow structure. Several transfer pipes 104 are connected to the heat exchange frame 103. These transfer pipes 104 are located below several battery blocks 3. The transfer pipe 104 located between four adjacent battery blocks 3 is connected to the first liquid inlet pipe 5. Transfer pipes located at the front and rear of the heat exchange frame 103... 104 is connected to the second inlet pipe 7; the coolant in the reservoir 101 is pumped into the heat exchange rack 103 by the pump 102 on the right side of the reservoir 101, and then the coolant in the heat exchange rack 103 is transferred from right to left through the transfer pipe 104. When the coolant in the transfer pipe 104 passes under the battery block 3, it performs heat exchange and cooling on the battery block 3 to prevent the battery block 3 from overheating and overloading during vehicle operation, thus extending the service life of the battery block 3. The coolant that has passed under the battery block 3 is sent back to the reservoir 101 for cooling by the pump 102 on the left side of the reservoir 101.

[0021] Each fin 4 is gradually lowered from the center to both sides in the horizontal direction. When the coolant leaks in the heat exchange assembly, the coolant is quickly guided to the lower side of the battery block 3 by the gradual downward movement of the fins 4 from the center to both sides in the horizontal direction. This prevents the coolant from adhering to the lower surface of the fins 4 for a long time and avoids the adhering coolant reducing the heat dissipation effect of the fins 4.

[0022] With a reference point of looking from the inside of the first nozzle 6 outwards, each first spray hole 6002 has a constricted structure; with a reference point of looking from the inside of the second nozzle 8 outwards, each second spray hole 8002 has a constricted structure. When coolant is sprayed from the constricted first spray hole 6002 and second spray hole 8002, it is beneficial to increase the pressure of the sprayed coolant, thereby increasing the coverage area of ​​the sprayed coolant and improving the fire extinguishing efficiency away from the ignition point of the first nozzle 6 and the second nozzle 8. At the same time, the increased pressure of the coolant when sprayed can improve the fire extinguishing effect on the fire source. Example 2

[0023] Based on Example 1, such as Figures 9-12As shown, the homogenizing system includes a heat-conducting plate 201, heat-conducting sheets 202, a fixing ring 203, and a heat insulation plate 204. Several heat-conducting plates 201 are fixedly attached to the upper surface of each fin 4, and these heat-conducting plates 201 are located outside adjacent first nozzles 6 and second nozzles 8. A fixing ring 203 is provided outside each first nozzle 6 and second nozzle 8. Several heat-conducting sheets 202 arranged in a ring array are fixedly attached to each fixing ring 203. Each heat-conducting sheet 202 overlaps with an adjacent heat-conducting plate 201. Several heat-conducting sheets 202 are fixedly attached to each fixing ring 203. Four heat insulation plates 204 arranged in a ring array are connected; each heat insulation plate 204 is located between two adjacent heat-conducting plates 202; the heat insulation plates 204 divide a plurality of first hot melt adhesives 6001 into four equal parts, and each part of the first hot melt adhesives 6001 faces the adjacent battery block 3; the heat-conducting plates 202 on both sides of each first hot melt adhesive 6001 and second hot melt adhesive 8001 are connected to the same fin 4 through the heat-conducting plates 201; the heat insulation plates 204 divide a plurality of second hot melt adhesives 8001 into two equal parts, and each part of the second hot melt adhesive 8001 faces the adjacent battery block 3. The hot melt adhesive 8001 faces the adjacent battery blocks 3 respectively; when a fire occurs in a battery block 3, the heat from the ignition point is conducted to the heat-conducting plate 201 near the fire source through the fins 4, and then the heat-conducting plate 201 conducts the heat to the heat-conducting sheets 202 on both sides of the first hot melt adhesive 6001 or the second hot melt adhesive 8001, causing the first hot melt adhesive 6001 or the second hot melt adhesive 8001 between the two heat-conducting sheets 202 to melt, and then the first nozzle 6 and the second nozzle 8 extinguish the fire at the ignition point. The heat is extinguished by the heat-conducting plate 201 and the heat-conducting sheets 202. The heat conduction is facilitated by the heat transfer, which accelerates the melting speed of the first hot melt adhesive 6001 and the second hot melt adhesive 8001, thereby improving the extinguishing efficiency of the first nozzle 6 and the second nozzle 8 at the ignition point. The heat insulation plate 204 blocks the two adjacent heat-conducting plates 202, preventing the first hot melt adhesive 6001 and the second hot melt adhesive 8001 from melting towards the side that is not on fire. This avoids the unburned battery block 3 being sprayed with coolant, thus preventing the unburned battery block 3 from short-circuiting and becoming unusable, and further saving vehicle maintenance costs.

[0024] The liquid distribution system also includes a propeller 207; each first nozzle 6 has a propeller 207 fixedly attached inside; each first inlet pipe 5 is rotatably connected to the adjacent first nozzle 6; when each battery block 3 catches fire, the first hot melt adhesive 6001 on the first nozzle 6 is melted, at which point the locking state of the first nozzle 6 is released, and coolant is sprayed out from the first nozzle 6. At the same time, through the flow of coolant, the propeller 207 drives the first nozzle 6 to rotate, further increasing the spray range of the first nozzle 6, so that the first nozzle 6 can fully spray coolant onto each battery block 3, avoiding fire extinguishing blind spots and enhancing the fire extinguishing effect of the first nozzle 6.

[0025] The liquid homogenization system also includes a base 205 and a first elastic element 206; a base 205 is fixedly connected to the outside of each first liquid inlet pipe 5; each base 205 has four sliding grooves 20501; the lower part of the fixing ring 203 is located in the sliding groove 20501, and a first elastic element 206 is fixedly connected in each sliding groove 20501. The first elastic element 206 is a spring; the first elastic elements 206 in the same base 205 are all fixedly connected to the lower part of the fixing ring 203; each first nozzle 6 has four oblique holes 6003 arranged in a ring array; each oblique hole 600... The heat-conducting plates 202 on the same side of each heat insulation plate 204 are all directed towards each other. When the propeller 207 drives the first nozzle 6 to rotate for fire extinguishing, the coolant sprayed through each inclined hole 6003 impacts the heat-conducting plates 202 on the same side of each heat insulation plate 204, causing the fixing ring 203 and the heat insulation plate 204 to rotate. This facilitates the spraying of coolant to the fire position between two adjacent battery blocks 3 that is blocked by the heat insulation plate 204 and the heat-conducting plates 202, further increasing the spray range of the first nozzle 6, avoiding fire extinguishing blind spots between two adjacent battery blocks 3, and further enhancing the fire extinguishing effect of the first nozzle 6. Example 3

[0026] Based on Examples 1 and 2, such as Figure 1 , Figure 2 , Figure 13 and Figure 14 As shown, it also includes a pressurization system, which includes a heat-conducting block 301, a hot melt wax 302, a sealing plate 303, and a second elastic element 304. Two heat-conducting blocks 301 are fixedly connected to the transmission pipe 104 between each pair of adjacent battery blocks 3. Each heat-conducting block 301 overlaps with the lower surface of the adjacent fin 4. A hot melt wax 302 is fixedly connected to the two heat-conducting blocks 301 on each transmission pipe 104 on opposite sides. A movable groove 10401 is opened on the transmission pipe 104 between each pair of adjacent battery blocks 3. Each movable groove 10401 is located to the right of the adjacent first liquid inlet pipe 5 and second liquid inlet pipe 7. A sealing plate 303 is provided in each movable groove 10401. The upper side of each sealing plate 303 overlaps with the adjacent hot melt wax 302. 2. Fixed connection; Several second elastic elements 304 are fixedly connected to the upper part of each sealing plate 303. The second elastic elements 304 are springs. When the battery blocks 3 catch fire, the heat from the ignition point is conducted to the heat-conducting block 301 through the fins 4. The heat from the heat-conducting block 301 melts the hot melt wax 302. At this time, the second elastic elements 304, which are in a stretched state, rebound downwards and reset, while driving the sealing plate 303 to move downwards. The sealing plate 303 blocks the transmission pipe 104, increases the pressure of the coolant entering the first liquid inlet pipe 5 and the second liquid inlet pipe 7, thereby increasing the coverage of the coolant sprayed from the first nozzle 6 and the second nozzle 8, improving the fire extinguishing efficiency of the first nozzle 6 and the second nozzle 8, and further improving the fire extinguishing effect on the fire source.

[0027] The connection point between the heat-conducting block 301 and the transmission pipe 104 is located on the right side of the movable groove 10401. When the vehicle chassis is damaged, causing the transmission pipe 104 to break, the movable groove 10401 on the transmission pipe 104 is relatively fragile compared to other parts of the transmission pipe 104, allowing the transmission pipe 104 to break at the location of the movable groove 10401. Simultaneously, the strong shock generated when the vehicle body 1 is damaged causes the hot melt wax 302 to detach from the heat-conducting block 301, thereby causing the second elastic element 304 to drive the sealing plate 303 to seal the transmission pipe 104. Since the coolant flows from right to left within the transmission pipe 104, and... The connection point between the heat-conducting block 301 and the transmission pipe 104 is located on the right side of the movable slot 10401. When the transmission pipe 104 breaks, the broken position of the transmission pipe 104 is sealed by the sealing plate 303 to prevent the coolant from spraying out over a large area and to avoid the battery pack 3 being short-circuited and scrapped due to coolant splashing. At the same time, since each movable slot 10401 is located to the right of the adjacent first liquid inlet pipe 5 and second liquid inlet pipe 7, when the transmission pipe 104 breaks and causes a fire inside the battery pack 2, the first nozzle 6 and the second nozzle 8 can perform fire extinguishing work normally, avoiding serious damage to the vehicle and further saving vehicle maintenance costs.

[0028] Several through holes 30201 are provided at each contact position between the hot melt wax 302 and the heat-conducting block 301. When the vehicle chassis is damaged, causing the transmission pipe 104 to break, the through holes 30201 facilitate the hot melt wax 302 to detach from the heat-conducting block 301, so that the sealing plate 303 can seal the broken position of the transmission pipe 104 in time. This prevents the hot melt wax 302 from failing to detach from the heat-conducting block 301 due to the strong shock generated when the vehicle body 1 is damaged, and avoids the sealing plate 303 failing to seal the broken position of the transmission pipe 104 in time, thus preventing further damage to the vehicle.
