Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a radiator for a charging pile. Background Technology

[0002] With the rapid development of new energy vehicles, charging piles, as an important supporting facility, are widely used in various outdoor and public places. During long-term operation, the electronic components inside the charging pile generate a large amount of heat. If this heat cannot be dissipated effectively and in a timely manner, it will affect the normal operation of the equipment and even cause safety hazards. Therefore, the heat sink, as an important component of the charging pile, directly affects the stability and service life of the equipment. Currently, traditional charging pile heat sinks mostly adopt a dense heat dissipation fin structure, relying on natural convection or forced cooling by fans to achieve heat exchange, which to a certain extent meets the basic heat dissipation requirements.

[0003] However, traditional radiators still have many shortcomings in practical applications. First, the gaps between the heat dissipation fins are too small, making it easy for dust to accumulate. After long-term use, this not only affects the aesthetics but also reduces heat dissipation efficiency and makes cleaning difficult. Second, most radiators have unreasonable structural designs, restricting airflow paths and resulting in poor natural convection, leading to low heat dissipation efficiency. Third, some radiators, in pursuit of lightweight design and cost control, use materials with insufficient strength, making the overall structure prone to deformation and affecting its long-term stability and safety.

[0004] The purpose of this invention is to solve the problems of traditional radiators, such as easy dust accumulation, difficulty in cleaning, low strength, and poor natural convection effect. Utility Model Content

[0005] The purpose of this invention is to solve the problems of traditional radiators, such as easy dust accumulation, difficulty in cleaning, low strength, and poor natural convection. This invention adopts the following technical solution:

[0006] A charging pile heat sink includes a heat sink body, wherein the heat sink body has rectangular grooves, trapezoidal grooves and triangular grooves, and the trapezoidal grooves and the triangular grooves are symmetrically distributed along both sides of the rectangular groove.

[0007] As described above, in a charging pile heat sink, the cross-sectional shape of the trapezoidal groove is a right trapezoid, and two trapezoidal grooves are respectively arranged on adjacent sides of the rectangular groove.

[0008] As described above, in a charging pile heat sink, the cross-sectional shape of the triangular groove is an isosceles triangle, and the triangular groove is disposed on one side of the trapezoidal groove.

[0009] In the charging pile heat sink described above, the inclined surface of the trapezoidal groove is parallel to the inclined surface of the triangular groove.

[0010] As described above, in a charging pile heat sink, the rectangular groove, the trapezoidal groove, and the triangular groove are arranged sequentially and spaced apart along the surface of the heat sink body, and the spacing between the rectangular groove, the trapezoidal groove, and the triangular groove is equal.

[0011] In the charging pile heat sink described above, the height of the cross-section of the rectangular groove, the height of the cross-section of the trapezoidal groove, and the height of the cross-section of the triangular groove are equal.

[0012] As described above, the corners of the rectangular groove, the trapezoidal groove, and the triangular groove of the charging pile heat sink are all rounded.

[0013] As described above, the radiator body of the charging pile has at least one mounting hole.

[0014] The heat sink for a charging pile described above is made of aluminum alloy.

[0015] Implementing the embodiments of this utility model has the following beneficial effects:

[0016] 1. In this utility model, by setting a composite structure of rectangular slots, trapezoidal slots and triangular slots on the heat sink body, not only is the heat dissipation area significantly increased, but the multi-channel design also effectively promotes natural air convection, achieving efficient passive heat dissipation and avoiding the energy consumption and reliability problems caused by traditional fan-forced cooling. At the same time, the open slot structure is less prone to dust accumulation than traditional heat sink fins and is easier to clean and maintain, improving ease of use. In addition, the trapezoidal slots and triangular slots are symmetrically distributed along the rectangular slots, forming a structural layout similar to reinforcing ribs, which enhances the overall mechanical strength and deformation resistance of the heat sink, and improves its stability and service life in complex environments.

[0018] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application.

[0023] 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.

[0024] like Figures 1 to 2 As shown, this utility model proposes a charging pile heat sink, including a heat sink body 1. The heat sink body 1 has rectangular slots 2, trapezoidal slots 3, and triangular slots 4, which are symmetrically distributed along both sides of the rectangular slot 2. The simultaneous arrangement of rectangular slots 2, trapezoidal slots 3, and triangular slots 4 not only increases the heat dissipation area but also promotes natural air convection by forming channels, avoiding the limitations of traditional forced cooling methods relying on fans. When hot air rises, cool air can enter from below, forming a continuous air circulation. The open slot structure is less prone to dust accumulation compared to traditional heat dissipation fins and is easier to clean and maintain. By setting rectangular slots 2, trapezoidal slots 3, and triangular slots 4, the structural strength of the charging pile heat sink can be strengthened. Specifically, the trapezoidal slots 3 and triangular slots 4 are symmetrically distributed along the rectangular slot 2, forming a structural layout similar to reinforcing ribs, further improving the mechanical strength and deformation resistance of the heat sink body 1.

[0025] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the trapezoidal groove 3 has a right-angled trapezoidal cross-section, and two trapezoidal grooves 3 are respectively disposed on adjacent sides of the rectangular groove 2. The triangular groove 4 has an isosceles triangle cross-section, and the triangular groove 4 is disposed on one side of the trapezoidal groove 3. The inclined plane of the trapezoidal groove 3 is parallel to the inclined plane of the triangular groove 4. Under stress, the rectangular groove 2 provides basic load-bearing capacity as the central structure, while the surrounding trapezoidal grooves 3 and triangular grooves 4 are symmetrically distributed through their inclined planes, forming a structural layout similar to "reinforcing ribs," which can effectively disperse external loads and internal thermal stresses, reducing the risk of local deformation. In particular, the right-angled trapezoidal design of the trapezoidal groove 3 makes its bottom connection with the radiator body 1 more robust, improving its bending and shear resistance; at the same time, due to its own structural characteristics, the triangular groove 4 has good mechanical stability and rigidity, further enhancing the overall structural robustness.

[0026] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the rectangular groove 2, the trapezoidal groove 3, and the triangular groove 4 are arranged sequentially at intervals along the surface of the radiator body 1, and the spacing between the rectangular groove 2, the trapezoidal groove 3, and the triangular groove 4 is equal. The consistent spacing and staggered distribution of the groove types allow heat and stress to be evenly transferred along the radiator body 1 under external loads or internal thermal stress, avoiding localized concentrated deformation. Simultaneously, the grooves of different shapes support each other, forming a synergistic force-bearing system similar to a "skeleton reinforcing rib," improving the overall structural rigidity and bending resistance.

[0027] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the heights of the cross-sections of the rectangular groove 2, the trapezoidal groove 3, and the triangular groove 4 are equal. Grooves of the same height exhibit a more consistent mechanical response under stress, which helps to reduce stress abrupt changes caused by dimensional differences and improves structural stability.

[0028] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the rectangular groove 2, the trapezoidal groove 3, and the triangular groove 4 all have rounded corners 5 at their corners. The rounded corners 5 effectively alleviate stress concentration at the corners of the grooves, allowing for a more even distribution of stress within the structure when the radiator is subjected to thermal expansion or external loads, thereby improving overall fatigue life and crack resistance. Simultaneously, the rounded corner transition avoids sharp corners and reduces vortex areas in airflow, making it less prone to dust adhesion and deposition, while also improving surface cleaning efficiency and facilitating daily maintenance.

[0029] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the radiator body 1 is provided with at least one mounting hole 6 for fixing the radiator to the inside of the charging pile or the surface of the outer casing by screws, rivets or other connectors. The presence of the mounting hole 6 ensures the overall firmness of the radiator installation, avoids displacement or loosening caused by vibration or wind pressure, and thus maintains long-term stable heat dissipation performance.

[0030] Optionally, in some embodiments, the radiator body 1 is made of aluminum alloy. Aluminum alloy has good mechanical strength and corrosion resistance, which can ensure that the radiator maintains structural stability during long-term use and is not easily deformed or damaged by oxidation.

[0031] Example 1:

[0032] This utility model proposes a charging pile heat sink, including a heat sink body 1. The heat sink body 1 has rectangular grooves 2, trapezoidal grooves 3, and triangular grooves 4, which are symmetrically distributed along both sides of the rectangular groove 2. The simultaneous arrangement of rectangular grooves 2, trapezoidal grooves 3, and triangular grooves 4 not only increases the heat dissipation area but also promotes natural air convection by forming channels, avoiding the limitations of traditional forced cooling methods relying on fans. As hot air rises, cool air can enter from below, forming a continuous air circulation. The open groove structure is less prone to dust accumulation compared to traditional heat dissipation fins and is easier to clean and maintain. By setting rectangular grooves 2, trapezoidal grooves 3, and triangular grooves 4, the structural strength of the charging pile heat sink can be strengthened. Specifically, the trapezoidal grooves 3 and triangular grooves 4 are symmetrically distributed along the rectangular groove 2, forming a structural layout similar to reinforcing ribs, further improving the mechanical strength and deformation resistance of the heat sink body 1. The heat sink body 1 is made of aluminum alloy. Aluminum alloy has good mechanical strength and corrosion resistance, ensuring that the heat sink maintains structural stability during long-term use and is not easily deformed or damaged by oxidation.

[0033] The trapezoidal groove 3 has a right-angled trapezoidal cross-section, with two trapezoidal grooves 3 positioned on adjacent sides of the rectangular groove 2. The triangular groove 4 has an isosceles triangle cross-section and is positioned on one side of the trapezoidal groove 3. The inclined surfaces of the trapezoidal groove 3 and the triangular groove 4 are parallel to each other. Under load, the rectangular groove 2 acts as the central structure, providing basic load-bearing capacity. The surrounding trapezoidal grooves 3 and triangular grooves 4 are symmetrically distributed through their inclined surfaces, forming a structural layout similar to "reinforcing ribs." This effectively disperses external loads and internal thermal stresses, reducing the risk of local deformation. In particular, the right-angled trapezoidal design of the trapezoidal groove 3 makes its bottom connection with the radiator body 1 more robust, improving its bending and shear resistance. At the same time, due to its structural characteristics, the triangular groove 4 exhibits good stability and rigidity in mechanics, further enhancing the overall structural strength.

[0034] Rectangular slots 2, trapezoidal slots 3, and triangular slots 4 are arranged sequentially and at intervals along the surface of the radiator body 1, with equal spacing between them. The consistent spacing and staggered distribution of the slots ensures that heat and stress are evenly distributed along the radiator body 1 under external loads or internal thermal stress, preventing localized deformation. Simultaneously, the different shaped slots support each other, forming a synergistic force-bearing system similar to a "skeleton reinforcing rib," enhancing the overall structural rigidity and bending resistance. The cross-sectional heights of rectangular slot 2, trapezoidal slot 3, and triangular slot 4 are equal. Slots of the same height exhibit a more consistent mechanical response under stress, which helps reduce stress abrupt changes caused by dimensional differences and improves structural stability.

[0035] The corners of rectangular groove 2, trapezoidal groove 3, and triangular groove 4 are all rounded with fillets 5. These fillets 5 effectively alleviate stress concentration at the corners of the grooves, allowing for a more even distribution of stress within the structure when the radiator is subjected to thermal expansion or external loads, thereby improving overall fatigue life and crack resistance. Simultaneously, the rounded transitions avoid sharp corners and reduce vortex zones in airflow, making it less prone to dust adhesion and deposition, while also improving surface cleaning efficiency and facilitating daily maintenance.

[0036] The radiator body 1 has at least one mounting hole 6 for fixing the radiator to the inside of the charging pile or the surface of the outer casing by screws, rivets or other connectors. The presence of the mounting hole 6 ensures the overall firmness of the radiator installation, avoids displacement or loosening caused by vibration or wind pressure, and thus maintains long-term stable heat dissipation performance.

[0037] Specifically, the working principle of this invention is as follows:

[0038] When the charging station generates heat during operation, the heat is transferred to the radiator body 1 through thermal conduction. The heated air rises and is discharged from each slot, while cool external air enters from below, forming a continuous natural air circulation. This composite slot structure not only increases the effective heat exchange area but also optimizes airflow organization, improves the overall natural convection efficiency, and avoids the energy consumption and reliability problems caused by traditional fan-based forced cooling methods.

[0039] The trapezoidal slot 3 has a right-angled trapezoidal cross-section, and two trapezoidal slots 3 are arranged on adjacent sides of the rectangular slot 2. The triangular slot 4 is an isosceles triangle, located on one side of the trapezoidal slot 3, with its inclined plane parallel to the inclined plane of the trapezoidal slot 3. This arrangement forms a structural layout similar to a "reinforcing rib." Under stress, the rectangular slot 2 acts as the central load-bearing structure, while the trapezoidal slots 3 and triangular slots 4 are symmetrically distributed through their inclined planes, effectively distributing the load and reducing local stress concentration. Furthermore, the rectangular slots 2, trapezoidal slots 3, and triangular slots 4 are arranged equidistantly along the surface of the radiator body 1 at consistent heights, further enhancing structural consistency and bending resistance. Rounded corners 5 are provided at the slot openings, which not only alleviate stress concentration but also reduce dust accumulation and improve cleaning convenience.

[0040] To facilitate assembly and fixation, the radiator body 1 has at least one mounting hole 6, allowing it to be securely connected to the inside of the charging pile or the surface of the outer casing using screws, riveting, or other methods. This design ensures a good fit between the radiator and the heat-generating element, improving heat transfer efficiency and enhancing the installation stability of the radiator under complex operating conditions, preventing displacement or loosening due to vibration or wind pressure. The radiator body 1 is made of aluminum alloy, which has excellent thermal conductivity, mechanical strength, and corrosion resistance.

[0041] In summary, this utility model solves the problems of traditional radiators being prone to dust accumulation, difficult to clean, and having poor natural convection.
