Description

Technical Field

[0001] This utility model relates to the field of power battery cooling technology, specifically a high-strength battery liquid cooling plate assembly. Background Technology

[0002] In new energy vehicles, the battery, as the core power source, is of paramount importance in terms of performance and safety. To ensure the stability and safety of the battery under different operating environments, an efficient thermal management system is essential. Liquid cooling technology, due to its high efficiency, space-saving design, and consistent cooling effect, is gradually becoming the mainstream battery cooling method. Through contact between the liquid cooling plate and the battery surface, heat is transferred to the coolant in the internal channels and carried away, thereby maintaining the battery's operating temperature within a reasonable range.

[0003] Although liquid cooling technology has been widely used in new energy vehicles, existing battery liquid cooling plate assemblies show significant shortcomings when faced with uneven road conditions during vehicle operation. When a vehicle is driving on bumpy roads or encounters large road obstacles, the chassis will be subjected to impacts and vibrations from the ground. In particular, traditional battery liquid cooling plate assemblies installed at the bottom of the vehicle are easily damaged by external impacts or compression due to their low overall structural strength. Such damage may not only lead to coolant leakage, affecting the normal operation of the cooling system, but more seriously, it may cause direct damage to the battery pack and even lead to safety accidents. Therefore, it is necessary to develop a battery liquid cooling plate assembly that can ensure efficient cooling while possessing higher strength and pressure resistance to cope with complex and changing driving environments and ensure the safety of the vehicle and its passengers.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7This utility model provides a technical solution: a high-strength battery liquid cooling plate assembly, including a housing assembly 100, a protective assembly 200 assembled inside the housing assembly 100, a liquid cooling pipe 300 communicating with the housing assembly 100 inside the protective assembly 200, a limiting assembly 400 installed on the outer wall of the liquid cooling pipe 300 on one side of the protective assembly 200, the limiting assembly 400 being used to limit the lateral position of the liquid cooling pipe 300, the limiting assembly 400 including a support base 410 that fits against the outer wall of the liquid cooling pipe 300, a reinforcing rib 420 provided at the bottom end of the support base 410, the reinforcing rib 420 being arranged along the length direction of the liquid cooling pipe 300. With this structure, when the vehicle is driving on bumpy roads or encountering large road obstacles, the chassis will be subjected to... When impacted or vibrated by the ground, the support base 410, by tightly fitting against the outer wall of the liquid cooling pipe 300, can quickly sense and absorb external pressure. The reinforcing ribs 420 at the bottom of the support base 410, arranged along the length of the liquid cooling pipe 300, further enhance the overall rigidity of the structure. These reinforcing ribs 420 not only disperse the pressure transmitted from the support base 410 but also, through their extended design, evenly distribute the force across the entire housing assembly 100, effectively preventing structural damage caused by localized stress concentration. Furthermore, the synergistic effect between the protective assembly 200 and the support base 410 ensures that the liquid cooling pipe 300 maintains a stable position even under external forces, preventing coolant leakage or damage to connections due to displacement. This high-strength design solves the problems of existing... In some technologies, battery liquid cooling plate assemblies suffer from insufficient structural strength when facing uneven road surfaces. This design significantly enhances the pressure resistance, ensures the normal operation of the cooling system, and improves the safety and reliability of the vehicle in complex driving environments. The housing assembly 100 includes a protective frame 110 connected to the protective assembly 200. One end of the protective frame 110 is equipped with a water inlet pipe 120, and the other end is equipped with a water outlet pipe 130. Mounting frames 140 extending through the protective frame 110 are provided on both sides. This structure ensures smooth flow of coolant through the water inlet and outlet pipes 120 and 130. The mounting frames 140 not only provide a stable connection point for the protective assembly 200 but also reinforce the entire housing assembly 100. With a structural strength of 0, the protective frame 110 can effectively resist external pressure and vibration when the vehicle encounters bumps or external impacts during driving, preventing structural deformation or damage caused by external impacts. Simultaneously, the mounting frame 140 ensures a tight fit between the protective component 200 and the housing component 100, allowing the protective component 200 to operate stably even in complex driving environments, preventing loosening or displacement caused by vibration. The protective component 200 includes two sets of mounting plates 210 adapted to the mounting frame 140, each set connected by an arc-shaped limiting strip 220. This structure of the mounting plates 210 ensures that the protective component 200 can be securely installed inside the housing component 100.The arc-shaped limiting strip 220 enhances the structural stability of the entire protection assembly 200 and makes the fit between the components tighter. Specifically, when the vehicle encounters bumps or external impacts during driving, the arc-shaped limiting strip 220 effectively absorbs and disperses external pressure, preventing direct pressure transmission to the liquid cooling pipe 300. The inlet pipe 120 and outlet pipe 130 are located on the same longitudinal horizontal plane, but not on the same transverse horizontal plane. Furthermore, the transverse horizontal plane of the inlet pipe 120 is higher than that of the outlet pipe 130. This structure ensures that the coolant flows smoothly into the housing assembly 100 from the inlet pipe 120 and flows naturally to the lower outlet pipe 130 under gravity. The inlet pipe 120 and outlet pipe... The 130° height difference helps create a natural flow path, avoiding liquid stagnation or bubble accumulation, thus improving the efficiency and reliability of the cooling system. This layout also reduces resistance to the coolant during inflow and outflow, ensuring smoother coolant flow, optimizing the entire cooling cycle, and enhancing the performance of the battery liquid cooling plate assembly. There are eight sets of liquid cooling pipes 300, equidistantly arranged along the length of the housing assembly 100. Each set of liquid cooling pipes 300 is semi-elliptical in shape. One end of each pipe is connected to the inlet pipe 120 via a sealing rubber ring, and the other end is connected to the outlet pipe 130 via a sealing rubber ring. This layout of eight sets of liquid cooling pipes 300 ensures that the coolant flows evenly through each... Each liquid cooling pipe 300 achieves efficient heat exchange. When coolant enters through the inlet pipe 120 and passes through each liquid cooling pipe 300, it finally flows out through the outlet pipe 130. Throughout this process, the semi-elliptical shape of the liquid cooling pipes 300 reduces flow resistance and improves cooling efficiency. Simultaneously, the equidistantly distributed liquid cooling pipes 300 ensure more uniform heat distribution, preventing localized overheating and improving battery cooling performance and system stability. The arc-shaped limiting strip 220 is composed of multiple interconnected semi-elliptical shapes and is hydraulically formed from spring steel strips. This structure provides excellent elasticity and pressure resistance, effectively absorbing and dispersing external pressure when encountering bumps or impacts during vehicle operation. The wavy structure of the arc-shaped limiting strip 220 not only increases its contact area but also ensures that pressure is evenly distributed along the semi-ellipse, avoiding local stress concentration. The material properties of the spring steel strip enable it to quickly return to its original shape after being compressed, ensuring long-term stability and reliability. The semi-circular arc of the arc-shaped limiting strip 220 is proportionally enlarged to the semi-circular arc of the liquid cooling pipe 300. When external pressure or vibration is transmitted to the arc-shaped limiting strip 220, its enlarged semi-circular arc can effectively distribute the force across the entire contact surface, preventing excessive local stress that could deform or damage the liquid cooling pipe 300. At the same time, this proportionally enlarged design ensures that there is no gap between the arc-shaped limiting strip 220 and the liquid cooling pipe 300, enhancing the system's sealing and stability.To prevent loosening or displacement caused by vibration or impact, nine sets of arc-shaped limiting strips 220 are used, with adjacent sets staggered. These nine sets are equidistantly distributed along the length of the liquid cooling pipe 300. This structure ensures that each set of arc-shaped limiting strips 220 is evenly distributed around the liquid cooling pipe 300, providing comprehensive support and protection. Thus, when the vehicle encounters bumps or external impacts during driving, the staggered arc-shaped limiting strips 220 can effectively disperse and absorb impacts from different directions. To prevent excessive localized stress and damage to the liquid cooling pipe 300, nine sets of equidistantly distributed arc-shaped limiting strips 220 ensure more balanced force transmission along the entire length. Two adjacent sets of liquid cooling pipes 300 are limited by eight sets of support seats 410. Each support seat 410 includes a top plate that abuts against the top of the inner wall of the protective frame 110. Two sets of first rubber strips are connected to the bottom of the top plate of the support seat 410. Each first rubber strip has a limiting arc-shaped plate at its bottom. A second rubber strip is also fitted to the bottom of the limiting arc-shaped plate, and a rubber base plate is fitted to the bottom of the second rubber strip. The rubber base plate is fixedly connected to the top of the reinforcing rib 420, and the bottom end of the reinforcing rib 420 abuts against the bottom end of the inner wall of the protective frame 110. The eight sets of support seats 410 in this structure ensure the stability and precise positioning of the liquid cooling pipe 300. Furthermore, the support seats 410 effectively absorb and disperse vibrations and impacts from the outside. The first and second rubber strips provide double buffering, preventing external pressure from being directly transmitted to the liquid cooling pipe 300 and protecting it from damage. The reinforcing rib 420 firmly connects the support seats 410 to the protective frame 110, ensuring the stability of the entire structure and preventing damage caused by external forces. Loosening or displacement caused by vibration or impact not only improves the system's pressure resistance and durability but also ensures the efficient operation of the cooling system. The limiting arc-shaped plate of the support base 410 fits against the side wall of the liquid cooling pipe 300, and the arc-shaped limiting strip 220 fits against the top and bottom of the liquid cooling pipe 300. This structure ensures that the liquid cooling pipe 300 is uniformly supported and limited in all directions, effectively preventing displacement or deformation of the liquid cooling pipe 300 due to external impact or vibration. The entire system can better absorb and disperse external pressure, avoiding damage caused by excessive local stress.

[0026] Working principle: When using this high-strength battery liquid cooling plate assembly, the coolant first enters the housing assembly 100 through the inlet pipe 120, and then flows through eight sets of liquid cooling pipes 300 evenly distributed along the length of the housing assembly 100. The coolant flows in from the inlet pipe 120, connects to one end of the liquid cooling pipe 300 through the sealing rubber ring, and after heat exchange through each liquid cooling pipe 300, it connects to the outlet pipe 130 through the sealing rubber ring, and finally flows naturally to the outlet pipe 130 by gravity. When the vehicle encounters bumps or external impacts during driving, the pressure is sensed and absorbed by the support base 410. The reinforcing ribs 420 at the bottom of the support base 410 disperse the pressure along its length and simultaneously strengthen the... The rib 420 abuts against the bottom of the inner wall of the protective frame 110, and the top plate of the support base 410 abuts against the top of the inner wall of the protective frame 110. The first and second rubber strips at the bottom of the top plate provide double buffering to prevent pressure from being directly transmitted to the liquid cooling pipe 300. The limiting arc plate at the bottom of the first rubber strip fits against the side wall of the liquid cooling pipe 300 to ensure the stability of the position of the liquid cooling pipe 300. At the same time, nine sets of arc limiting strips 220 are staggered along the length of the liquid cooling pipe 300 and evenly distributed around the liquid cooling pipe 300 to further enhance the pressure resistance of the system. Throughout the process, the coolant always maintains efficient flow. Through the coordinated work of the above components, the cooling cycle is completed, thereby completing a series of tasks.
