Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, specifically to a heat sink. Background Technology

[0002] In the fields of electronic and mechanical equipment, as the power density of equipment continues to increase, the heat generated during its operation also increases significantly. If this heat cannot be dissipated in a timely and effective manner, it will cause the internal temperature of the equipment to rise, thereby affecting the working stability and service life of the equipment, and even causing equipment failure. Therefore, radiators, as important heat dissipation components, are widely used in various types of equipment.

[0003] However, traditional heat sinks mostly employ a uniform fin design, which easily leads to laminar airflow between the fins, resulting in limited heat exchange efficiency. Furthermore, they struggle to balance large-area heat dissipation with compact layout within a limited space, especially in scenarios involving multi-power module integration. A single-structure heat sink often cannot be designed to address the differentiated heat dissipation needs of different areas, leading to localized heat accumulation and impacting overall device performance. Therefore, there is an urgent need to design a heat sink to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a radiator to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A radiator includes a plate body, and a heat dissipation assembly three is provided on the top of the plate body. The heat dissipation assembly three includes a plurality of heat dissipation fins three bolted to the top of the plate body. The top of the heat dissipation fins three is provided with a through groove two, and the through groove two is arranged in a staggered manner at the top position of the heat dissipation fins three.

[0007] Both sides of the heat dissipation component three are provided with heat dissipation component two. The heat dissipation component two includes several heat dissipation fins two bolted to the top of the plate. A through groove one is opened in the middle of the top of the heat dissipation fin two.

[0008] Both sides of the heat dissipation component 2 are provided with heat dissipation component 1. The heat dissipation component 1 includes several heat dissipation fins 1 bolted to the plate body. A groove is provided on one side of each heat dissipation fin 1.

[0009] Preferably, the plate body has a plurality of limiting holes on its periphery and mounting holes on its bottom. The heat dissipation components one, two, and three are bolted to the plate body through the mounting holes.

[0010] Preferably, a fixing hole is provided on one side of the top of the plate, and the fixing hole is used at least for fixing the heat sink.

[0011] Preferably, the cross-section of the groove is trapezoidal, the groove extends along one direction of the heat dissipation component, and penetrates the heat dissipation component.

[0012] Preferably, the groove on the first heat sink is connected to the through groove on the second heat sink to form a through heat dissipation channel.

[0013] Preferably, the through slots 2 on all the heat sinks 3 together form a continuous V-shaped airflow channel, and the two ends of the V-shaped airflow channel are respectively directed toward the heat dissipation components 2 on both sides.

[0014] In the above technical solution, the radiator provided by this utility model has the following beneficial effects:

[0015] (1) By setting up three different heat dissipation components, combined with the design of groove, through slot one and staggered through slot two, the heat dissipation area is significantly increased. The groove of heat sink one and the through slot one of heat sink two form a through heat dissipation channel. The staggered through slot two of heat sink three encloses and forms a V-shaped airflow channel, which effectively enhances airflow disturbance, breaks laminar flow restriction, accelerates heat exchange, and improves overall heat dissipation efficiency.

[0016] (2) The through-type heat dissipation channel and the V-shaped airflow channel work together to enable the airflow to form an orderly circulation inside the heat sink, avoiding local heat accumulation. The two ends of the V-shaped airflow channel face the heat dissipation component 2, further guiding the airflow to flow efficiently between the components and improving the heat dissipation speed.

[0024] like Figure 1-4 As shown, an embodiment of the present invention provides a radiator including a plate body 1. A heat dissipation assembly 3 7 is provided on the top of the plate body 1. The heat dissipation assembly 3 7 includes a plurality of heat dissipation fins 3 71 bolted to the top of the plate body 1. A through groove 2 72 is provided on the top of the heat dissipation fins 3 71. The through grooves 2 72 are staggered and arranged at the top positions of the heat dissipation fins 3 71. Heat dissipation assemblies 2 6 are provided on both sides of the heat dissipation assembly 3 7. The heat dissipation assembly 2 6 includes a plurality of heat dissipation fins 2 61 bolted to the top of the plate body 1. A through groove 1 62 is provided at the middle position of the top of the heat dissipation fins 2 61. Heat dissipation assemblies 1 5 are provided on both sides of the heat dissipation assembly 2 6. The heat dissipation assembly 1 5 includes a plurality of heat dissipation fins 1 51 bolted to the plate body 1. A groove 52 is provided on one side of the heat dissipation fins 1 51.

[0025] In this embodiment, a plate body 1 is included. A heat dissipation assembly 7 is provided on the top of the plate body 1 and installed at the center of the top of the plate body 1. It is connected to the plate body 1 by bolts. The heat dissipation assembly 7 includes several heat dissipation fins 71 bolted to the top of the plate body 1. The heat dissipation fins 71 are all made of metal material with high thermal conductivity and are arranged vertically in the center area of ​​the top of the plate body 1.

[0026] The top of the heat sink 3 71 is provided with a through slot 2 72, which is opened along the width direction of the heat sink 3 71. The width is set according to the heat dissipation requirements. The through slots 2 72 are staggered and arranged at the top position of the heat sink 3 71.

[0027] The second through slot 72 is arranged in a staggered manner on the top of the third heat sink 71. That is, the second through slot 72 on two adjacent third heat sinks 71 is biased to the left side of the third heat sink 71, the next one is biased to the right side of the third heat sink 71, and so on.

[0028] This staggered arrangement allows the through slots 72 on all the heat sinks 71 to form a continuous V-shaped airflow channel. The two ends of the V-shaped airflow channel face the heat dissipation components 6 on both sides, providing a specific guiding path for the airflow.

[0029] Heat dissipation component 7 is provided on both sides of heat dissipation component 2 6. Heat dissipation component 2 6 is also connected to plate 1 by bolts. Heat dissipation component 2 6 includes several heat dissipation fins 2 61 bolted to the top of plate 1. The material of heat dissipation fins 2 61 is the same as that of heat dissipation fin 3 71 to ensure the consistency of overall thermal conductivity.

[0030] A through slot 62 is provided at the top center of the heat sink 2 61. The through slot 62 is opened along the width direction of the heat sink 2 61. The center line of the through slot 62 coincides with the center line of the heat sink 2 61. All the through slots 62 on the heat sink 2 61 are on the same horizontal straight line, forming a horizontal airflow channel. The inner end of the channel is connected to both ends of the V-shaped airflow channel of the heat dissipation component 3 7, and the outer end is connected to the groove 52 of the heat dissipation component 1 5, so as to realize the smooth flow of airflow between different heat dissipation components.

[0031] Heat dissipation component 1 5 is provided on both sides of heat dissipation component 2 6. A set of heat dissipation component 1 5 is provided on the far left and far right of the top of the plate 1. Heat dissipation component 1 5 includes several heat dissipation fins 1 51 bolted to the plate 1. The material of heat dissipation fins 1 51 is the same as that of heat dissipation fins 2 61 and heat dissipation fins 3 71 to ensure efficient heat transfer.

[0032] A groove 52 is provided on one side of the heat sink 51. The cross-section of the groove 52 is trapezoidal, with the upper base width being greater than the lower base width. This structural design can increase the contact area with airflow and improve heat dissipation efficiency.

[0033] Specifically, the plate 1 has several limiting holes 2 on its periphery. The plate 1 is a rectangular flat plate structure. Its size is set according to the requirements of the heat dissipation equipment. Several limiting holes 2 are evenly distributed on the periphery edge. The limiting holes 2 penetrate the upper and lower end faces of the plate 1. The spacing between adjacent limiting holes 2 is consistent.

[0034] The bottom of the plate 1 is provided with mounting holes 3. Heat dissipation components 1, 5, 6, and 7 are bolted to the plate 1 through the mounting holes 3. The number of mounting holes 3 matches the total installation requirements of heat dissipation components 1, 5, 6, and 7, and the inner wall of the mounting holes 3 is provided with an internal thread structure.

[0035] Specifically, a fixing hole 4 is provided on one side of the top of the plate 1. The fixing hole 4 is used to fix the heat sink. The fixing hole 4 also penetrates the upper and lower end faces of the plate 1 and has internal threads on the inner wall. Its main function is to connect with the fixing structure of the external equipment through bolts, and to firmly fix the entire heat sink to the equipment that needs heat dissipation, so as to prevent the heat sink from shifting due to vibration and other factors during operation and to ensure the stability of the heat dissipation effect.

[0036] Specifically, the cross-section of the groove 52 is trapezoidal, and the groove 52 extends along the direction of the heat dissipation component 5 and penetrates the heat dissipation component 5.

[0037] Specifically, the groove 52 on heat sink 51 is connected to the through slot 62 on heat sink 61 to form a through heat dissipation channel.

[0038] Specifically, the through slots 72 on all the heat sinks 71 together form a continuous V-shaped airflow channel, with the two ends of the V-shaped airflow channel facing the heat dissipation components 6 on both sides.

[0039] Work steps: 1. Use the limiting holes 2 on the side of the plate to align the assembled heat sink with the positioning structure of the external equipment;

[0040] 2. The radiator is initially positioned by the limiting hole 2 to prevent positional displacement during subsequent fixing;

[0041] 3. According to the installation requirements of the external equipment, the positioned heat sink is installed through the mounting hole 3 at the bottom of the board 1 or the fixing hole 4 on the top side.

[0042] 4. Use compatible bolts to connect to the mounting structure of external equipment to ensure that the radiator is firmly fixed and without any loosening.

[0043] 5. Check whether the bolts of all heat dissipation components 1 (5), 2 (6), and 3 (7) are tight, and whether heat sink 1 (51), 2 (61), and 3 (71) are tilted.

[0044] 6. Confirm that the through-type heat dissipation channel groove 52 and through groove one 62 and the V-shaped airflow channel through groove two 72 are unobstructed and unblocked by any components.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
