Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, and more specifically, to a battery liquid cooling plate structure. Background Technology

[0002] As a core heat dissipation component of battery modules, liquid cooling plates must efficiently dissipate heat while withstanding the weight of the battery module and loads such as vibration and impact during vehicle operation. Existing liquid cooling plates mostly adopt a single flat plate structure directly mounted to the battery casing, or are fixed using simple brackets. However, in heavy-duty battery module applications (such as commercial vehicles and energy storage battery systems), traditional fixing methods have significant drawbacks:

[0003] On the one hand, the contact area between the liquid cooling plate and the supporting structure is limited, and local load concentration can easily lead to deformation of the liquid cooling plate, or even cause leakage in the internal flow channel, affecting heat dissipation performance and safety. On the other hand, the industry generally adopts the method of reducing the thickness of the raw materials of the product and increasing the overall strength by adding rib structure. However, this improvement can only increase the overall strength by about 15%, which is far lower than the load-bearing requirements. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a battery liquid cooling plate structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A battery liquid cooling plate structure includes a liquid cooling plate body disposed on a load-bearing plate; the load-bearing plate includes a frame, which consists of two parallel frames, and a front support plate, a rear support plate, and a heavy-duty support plate are connected between the two frames. The heavy-duty support plate is spaced between the front support plate and the rear support plate, so that the front support plate, the rear support plate, and the heavy-duty support plate together form a tray for mounting the liquid cooling plate body, and the tray is in contact with the back of the liquid cooling plate body.

[0007] Furthermore, the above solution incorporates a hollowed-out structure in the keel frame, which effectively reduces weight while maintaining overall strength.

[0008] Furthermore, the above solution includes a slot on the keel frame to provide a positioning and installation reference for the front support plate, rear support plate, and heavy-duty support plate, while also allowing for some clearance.

[0009] Furthermore, the above solution adopts an inlay-and-lock structure on the mating surface between the front support plate and the liquid cooling plate, so that it matches the shape of the front and back sides of the liquid cooling plate.

[0010] Furthermore, the above solution adopts an inlay-locking structure for the mating surface between the rear support plate and the liquid cooling plate, so that it matches the shape of the rear back side of the liquid cooling plate.

[0011] Furthermore, the above solution includes three heavy-duty pallets that are equidistantly distributed between the front and rear pallets.

[0012] Furthermore, the above solution includes a groove structure on the mating surface between the heavy-duty support plate and the liquid-cooled plate, which matches the flow channel shape on the back side of the middle of the liquid-cooled plate.

[0013] Furthermore, the above solution includes an additional groove structure perpendicular to the groove structure to ensure the overall strength of the heavy-duty pallet.

[0014] Furthermore, in the above solution, the front support plate, rear support plate, and heavy-duty support plate are connected to the two keel frames by fastening screws.

[0015] Furthermore, in the above solution, the tray and the liquid cooling plate are fastened together by rivet nuts or bolts.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model uses two parallel keel frames as a rigid foundation. With the tray composed of the front support plate, rear support plate, and heavy-duty support plate, the load of the liquid cooling plate is distributed to multiple support points, avoiding local stress concentration, improving load-bearing capacity to adapt to heavy-duty scenarios, enhancing vibration and shock resistance, and facilitating installation and maintenance with strong compatibility. At the same time, it does not affect the heat dissipation function. The tray only contacts the back of the liquid cooling plate, avoiding obstruction of heat dissipation channels or heat dissipation fins, ensuring that the heat dissipation area of ​​the liquid cooling plate is not affected, and providing a strong guarantee for the reliable operation of the liquid cooling system of new energy batteries.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0024] A battery liquid cooling plate structure includes a liquid cooling plate body 1, which is disposed on a load-bearing plate 2. The load-bearing plate 2 includes a frame 21, which consists of two parallel frames. The two frames 21 are connected together by fastening screws to a front support plate 22, a rear support plate 23, and a heavy-duty support plate 24. The heavy-duty support plate 24 is spaced between the front support plate 22 and the rear support plate 23, so that the front support plate 22, the rear support plate 23, and the heavy-duty support plate 24 together form a tray for mounting the liquid cooling plate body 1. The tray contacts the back (non-heat dissipation surface) of the liquid cooling plate body 1 and is fastened by rivet nuts or bolts.

[0025] In this design, two parallel keel frames 21 serve as a rigid foundation. Front support plates 22 and rear support plates 23 are used to limit movement and prevent shifting. Combined with heavy-duty support plates 24 set at intervals to disperse the load in the middle, they together form a tray that supports the liquid cooling plate 1. The tray can not only improve the load-bearing capacity by dispersing the load to adapt to heavy-duty battery modules, but also enhance the stability against vibration and impact by using front and rear limits and overall rigidity. At the same time, it is easy to install and maintain, has strong compatibility, and does not affect the heat dissipation function of the liquid cooling plate 1.

[0026] In the above scheme, the specific structure of the keel frame 21 is as follows:

[0027] The keel frame 21 is formed by bending or extrusion to create a hollow structure 211, which effectively reduces weight while ensuring overall strength. It is provided with slots 212 to provide a positioning and installation benchmark for the front support plate 22, the rear support plate 23 and the heavy-duty support plate 24, while also allowing for some clearance. The whole is based on the keel frame 21 and combined with the pallet, which not only strengthens the load distribution and vibration resistance stability, but also improves the ease of installation and structural rationality through lightweight design and precise positioning. It also takes into account heat dissipation function and is suitable for heavy-duty scenarios with high reliability requirements.

[0028] In the above scheme, regarding the structure of the front support plate 22:

[0029] The mating surface between the front support plate 22 and the liquid cooling plate 1 adopts an inlay and snap-fit ​​structure, which makes it fit the shape of the front back of the liquid cooling plate 1. This design can effectively increase the direct contact area between the two, thereby avoiding squeezing damage between the liquid cooling plate 1 and the front support plate 22 when the liquid cooling plate 1 is subjected to force.

[0030] In the above scheme, regarding the structure of the rear support plate 23:

[0031] The mating surface between the rear support plate 23 and the liquid cooling plate 1 adopts an inlay and snap-fit ​​structure, which makes it fit the shape of the rear back of the liquid cooling plate 1. This design can effectively increase the direct contact area between the two, thereby avoiding squeezing damage between the liquid cooling plate 1 and the rear support plate 23 when the liquid cooling plate 1 is subjected to force.

[0032] In the above scheme, regarding the structure of the heavy-duty pallet 24:

[0033] There are three heavy-duty pallets 24, which are equidistantly distributed between the front pallet 22 and the rear pallet 23. The mating surface of the pallet 24 with the liquid cooling plate 1 is provided with a groove structure 241, which matches the flow channel shape on the back of the middle part of the liquid cooling plate 1. At the same time, a groove structure 242 perpendicular to the groove structure 241 is also added to ensure the overall strength of the heavy-duty pallet 24.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
