Abstract
Description
Technical Field
[0001] This utility model belongs to the field of heat dissipation fin technology, specifically relating to an assembled heat dissipation fin for a new energy vehicle radiator. Background Technology
[0002] In the field of new energy vehicles, the radiator, as a crucial component ensuring the normal operation of key parts such as batteries and motors, directly affects the vehicle's performance and reliability. With the continuous development of new energy vehicle technology, higher demands are being placed on radiators in terms of heat dissipation efficiency, lightweight design, and durability.
[0003] Traditional automotive radiator fins often employ a flat plate structure, resulting in limited contact area with air and low heat transfer efficiency. Even those using non-flat plate structures lack effective airflow turbulence. As air flows over the fin surface, a stable boundary layer easily forms, hindering heat exchange and further impairing cooling. Furthermore, the traditional fin design prevents even heat distribution across the entire fin, leading to localized overheating and affecting the overall performance and stability of the radiator. Installation is complex, lacking precise positioning. Significant time is spent adjusting and aligning the fins, increasing difficulty and labor costs, and making it difficult to ensure accurate relative positioning. Inaccurate installation further obstructs airflow, reducing cooling efficiency. Moreover, some traditional installations are non-removable, making repair and replacement difficult if fins are damaged, necessitating complete radiator replacement, wasting resources and increasing costs.
[0004] In view of this, we propose an assembled heat dissipation fin for a new energy vehicle radiator to solve the above problems. Utility Model Content
[0005] The present invention aims to solve the technical problem that in the prior art, heat dissipation fins mostly adopt a flat plate structure, which has a limited contact area with air, resulting in low heat transfer efficiency and poor heat dissipation effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A prefabricated heat dissipation fin for a new energy vehicle radiator includes a heat dissipation fin body and a mounting plate for mounting the heat dissipation fin body onto a radiator base.
[0008] The heat dissipation fin body includes several heat dissipation fins arranged at equal intervals, with a wave-shaped structure, consisting of multiple continuous peaks and troughs, as well as an upper heat dissipation plate and a lower heat dissipation plate connecting two adjacent heat dissipation fins; the upper heat dissipation plate and the lower heat dissipation plate are provided with several vertically arranged heat dissipation baffles;
[0009] The mounting plate has insertion slots for inserting heat sinks and positioning the lower heat sink plate. Several mounting holes are provided on both sides of the mounting base. The heat sink body is fixed to the mounting plate by screws that pass through the mounting holes and are threaded to the heat sink.
[0010] As a preferred option, the upper and lower heat sinks are staggered.
[0011] Preferably, the heat dissipation folding plate is bent vertically towards the heat sink along the grooves cut on the upper and lower heat dissipation plates.
[0012] Preferably, the heat dissipation folds are located between the crests and troughs of two adjacent heat sinks, with two symmetrically arranged heat dissipation folds between the crests and troughs.
[0013] Preferably, a downward-opening heat dissipation channel A is formed between two adjacent heat sinks and the upper heat dissipation plate, and an upward-opening heat dissipation channel B is formed between two adjacent heat sinks and the lower heat dissipation plate.
[0014] Preferably, several heat dissipation folds are located in their respective heat dissipation channels A and B.
[0015] Preferably, the heat sink fins and mounting plate are made of aluminum alloy or copper alloy.
[0016] Preferably, the mounting plate has four mounting positions at each of its four corners, and the mounting plate is fixed to the radiator base by bolts passing through the mounting positions.
[0017] Compared with the prior art, the technical effects and advantages of this utility model are:
[0018] 1. The assembled heat dissipation fins of this new energy vehicle radiator feature a wave-shaped structure composed of multiple continuous peaks and troughs. Compared to a flat structure, this significantly increases the contact area with the air, allowing more heat to be transferred to the surrounding air through a larger surface area, thus improving heat dissipation efficiency. The upper and lower heat dissipation plates are staggered, forming heat dissipation channels A and B with opposite opening directions. As air flows through these channels, a complex airflow path is created, generating strong turbulence that disrupts the boundary layer formed on the heat dissipation surface, allowing for more thorough heat exchange between the air and the surface, further enhancing the heat dissipation effect.
[0019] 2. Multiple equidistant heat sinks and staggered upper and lower heat sink plates ensure even heat distribution across the entire heat sink fin body, preventing localized overheating and guaranteeing the overall stability of the radiator's heat dissipation performance. Heat dissipation folds are vertically bent towards the heat sink fins along the grooves on the upper and lower heat sink plates, located between the crests and troughs of adjacent heat sink fins, increasing the additional heat dissipation area and further improving heat dissipation efficiency. Located within heat dissipation channels A and B, the heat dissipation folds obstruct and guide airflow, making it more turbulent and enhancing air disturbance, thus more effectively removing heat from the heat dissipation surface and improving heat exchange efficiency.
[0020] 3. The insertion slots on the mounting plate allow for the insertion and positioning of the heatsink fins and lower heatsink plate. This insertion method enables quick and accurate initial positioning of the heatsink fins relative to the mounting plate, reducing adjustment time and difficulty during installation. The heatsink fins are then secured to the mounting plate with screws that pass through the mounting holes and are threaded onto the heatsink. This detachable connection facilitates subsequent maintenance and replacement of the heatsink fins. The insertion slots and mounting holes on the mounting plate ensure accurate positioning of the heatsink fins, guaranteeing the relative positional precision between the heatsink fins and the radiator base, resulting in smoother airflow and improved heat dissipation efficiency.
[0021] 4. The mounting plate is fixed to the radiator base with bolts at the four corners of the mounting plate. This connection method is simple and reliable, and can ensure that the heat dissipation fins are tightly connected to the radiator base, so that heat can be smoothly transferred from the base to the heat dissipation fins. At the same time, it is convenient to install and remove the entire assembled heat dissipation fins on the radiator. Attached Figure Description

[0029] 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.
[0030] The following combination Figures 1 to 5 This application will be described in further detail.
[0031] This application discloses an assembled heat dissipation fin for a new energy vehicle radiator, including a heat dissipation fin body 100 and a mounting plate 200 for mounting the heat dissipation fin body 100 onto a radiator base; the heat dissipation fin body 100 and the mounting plate 200 are made of aluminum alloy or copper alloy.
[0032] Both aluminum and copper alloys possess excellent thermal conductivity. The thermal conductivity of aluminum alloys is typically between 180-230 W / (m·K), while copper alloys have even higher conductivity, usually reaching 200-400 W / (m·K). In radiators for new energy vehicles, this conductivity allows for rapid heat transfer from the heat source to the surface of the heat sink fins, improving heat dissipation efficiency and ensuring that the radiator can effectively dissipate the heat generated by components such as the battery and motor, guaranteeing that key components of the new energy vehicle operate within a suitable temperature environment.
[0033] Aluminum alloys have a relatively low density, approximately 2.7 g / cm³. 3 Compared to traditional steel materials (density approximately 7.8 g / cm³), 3 It is much lighter. In the context of new energy vehicles pursuing lightweight design to improve driving range, using aluminum alloy or copper alloy to make heat dissipation fins can reduce the weight of the entire radiator, thereby reducing the overall vehicle weight and energy consumption.
[0034] Aluminum and copper alloys can form a dense oxide film on their surfaces. This oxide film prevents oxygen, moisture, and other substances from reacting further with the metal substrate, providing excellent corrosion resistance. In the complex operating environment of automobiles, it effectively resists the erosion of rainwater, moisture, and chemicals, extending the service life of the heat sink fins and ensuring the long-term stable operation of the radiator.
[0035] The heat dissipation fin body 100 includes several heat dissipation fins 13 arranged at equal intervals, with a wave-shaped structure, and composed of multiple continuous peaks 11 and troughs 12, as well as an upper heat dissipation plate 14 and a lower heat dissipation plate 15 connecting two adjacent heat dissipation fins 13; the upper heat dissipation plate 14 and the lower heat dissipation plate 15 are staggered, and a downward-opening heat dissipation channel A18 is formed between two adjacent heat dissipation fins 13 and the upper heat dissipation plate 14, and an upward-opening heat dissipation channel B19 is formed between two adjacent heat dissipation fins 13 and the lower heat dissipation plate 15.
[0036] The wave-shaped heat sink 13 consists of multiple continuous peaks 11 and troughs 12, which greatly increases the contact area between the heat sink fins and the air compared to a flat structure. More heat can be transferred to the surrounding air through the larger surface area, thereby improving heat dissipation efficiency.
[0037] The upper heat sink 14 and the lower heat sink 15 are staggered to form heat dissipation channels A18 and B19 with opposite opening directions. When air flows through these heat dissipation channels, it forms a complex airflow path, generating strong turbulence. This turbulence can disrupt the boundary layer formed by the air on the heat dissipation surface, allowing for more efficient heat exchange between the air and the heat dissipation surface, thus further improving the heat dissipation effect.
[0038] Multiple equidistant heat sinks 13 and staggered upper and lower heat sink plates 14 and 15 ensure that heat is evenly distributed across the entire heat sink body 100. This prevents localized overheating and ensures stable overall heat dissipation performance of the radiator.
[0039] The upper heat sink 14 and the lower heat sink 15 are provided with a number of vertically arranged heat dissipation folding plates 16; the heat dissipation folding plates 16 are bent vertically towards the heat sink 13 along the position of the groove 17 on the upper heat sink 14 and the lower heat sink 15.
[0040] The heat dissipation folding plate 16 is located between the peaks 11 and peaks 11 and troughs 12 of two adjacent heat sinks 13. Two symmetrically arranged heat dissipation folding plates 16 are arranged between the peaks 11 and peaks 11, and two symmetrically arranged heat dissipation folding plates 16 are also arranged between the troughs 12 and troughs 12. Several heat dissipation folding plates 16 are respectively located in the corresponding heat dissipation channels A18 and B19.
[0041] The heat dissipation folds 16 are bent vertically towards the heat sink 13 along the grooves 17 on the upper heat sink 14 and the lower heat sink 15, increasing the additional heat dissipation area. These heat dissipation folds 16 are located between the crests 11 and troughs 12 of adjacent heat sinks 13, further expanding the contact area with air and improving heat dissipation efficiency.
[0042] The heat dissipation baffle 16 is located within the heat dissipation channels A18 and B19. When air flows through these channels, the heat dissipation baffle 16 obstructs and guides the airflow, making it more turbulent and increasing the degree of air disturbance. This enhanced air disturbance can more effectively remove heat from the heat dissipation surface and improve heat exchange efficiency.
[0043] The heat dissipation fin 16 also provides structural support, enhancing the strength and stability of the upper heat dissipation plate 14 and the lower heat dissipation plate 15. When subjected to airflow pressure or other external forces, it better maintains the structural integrity of the heat dissipation fin body 100. The groove 17 also facilitates improved heat dissipation efficiency.
[0044] The mounting plate 200 has insertion slots 21 for inserting the heat sink 13 and positioning the lower heat sink 15. Several mounting holes 22 are provided on both sides of the mounting base. Screws passing through the mounting holes 22 and threadedly connected to the heat sink 13 are used to fix the heat sink fin body 100 onto the mounting plate 200. Four mounting positions 23 are provided at each of the four corners of the mounting plate 200. Bolts passing through the mounting positions 23 are used to install and fix the mounting plate 200 onto the heat sink base.
[0045] The mounting plate 200 is equipped with insertion slots 21 for inserting the heat sink 13 and positioning the lower heat sink 15. This insertion method allows for quick and accurate initial positioning of the heat sink fin body 100 to the mounting plate 200, reducing adjustment time and difficulty during installation. Simultaneously, screws passing through the mounting holes 22 and threadedly connected to the heat sink 13 secure the heat sink fin body 100 to the mounting plate 200. This detachable connection facilitates subsequent maintenance and replacement. The design of the insertion slots 21 and mounting holes 22 on the mounting plate 200 ensures accurate positioning of the heat sink fin body 100 on the mounting plate 200, guaranteeing the relative positional accuracy between the heat sink fins and the radiator base. This is crucial for the overall heat dissipation performance of the radiator, as accurate installation allows for smoother airflow and improved heat dissipation efficiency.
[0046] The mounting plate 200 has four mounting positions 23 at each of its four corners. The mounting plate 200 is fixed to the radiator base by bolts passing through the mounting positions 23. This connection method is simple and reliable, ensuring a tight fit between the heat dissipation fins and the radiator base, allowing heat to be smoothly transferred from the radiator base to the heat dissipation fins. It also facilitates the installation and removal of the entire assembled heat dissipation fin assembly on the radiator.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
