Detailed Description

The utility model provides a radiator section, which is described in further detail below by referring to the accompanying drawings and embodiments in order to make the purpose, technical scheme and effect of the utility model clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In the description of the present invention, it is to be understood that the terms "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation and a specific orientation configuration and operation, and thus, should not be construed as limiting the present invention. Furthermore, "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, unless otherwise specified, "a plurality of blocks" means two or more blocks.

Referring to fig. 1, the present invention provides a heat sink profile, which includes a cylindrical base 1, wherein a plurality of heat dissipation fins 2 and a plurality of connecting fins 3 are circumferentially disposed on the cylindrical base 1; the radiating fins 2 and the connecting fins 3 are both arc-shaped; the distance between the outer end of the connecting fin 3 and the cylindrical base 1 is greater than the distance between the outer end of the radiating fin 2 and the cylindrical base 1; the outer end of the connecting fin 3 is provided with a fixing groove 31. The cylindrical base 1 is in contact with a heat-generating electronic component for absorbing heat generated from the electronic component, and then the heat is radiated from the cylindrical base 1 to the arc-shaped heat radiation fins 2 and the connection fins 3. Compared with straight rod-shaped fins, the arc-shaped radiating fins 2 or the connecting fins 3 are longer in length in the space with the same size, the surface area is larger, the contact area of the fins and air is larger, and the radiating effect is better. The connecting fins 3 are used for fixing the radiator section, the fixing grooves 31 are arranged at the outer side ends of the connecting fins 3, and the space occupied by the fixing area in the middle heat conducting area and the heat radiating area is reduced.

Referring to fig. 2, the heat dissipation fins 2 include a first heat dissipation portion located at an outer side and a second heat dissipation portion 21 located at an inner side, the first heat dissipation portion includes a plurality of first fins 22, and inner ends of the plurality of first fins 22 are respectively connected to the second heat dissipation portion 21; the inner end of the second heat sink 21 is connected to the cylindrical base 1. The heat dissipation fins 2 extend from the center to the outer periphery, the outer periphery has a larger space than the inner periphery, and the plurality of first fins 22 arranged on the first heat dissipation part positioned at the outer side can fully utilize the space of the outer periphery and enlarge the surface area. Preferably, the first heat sink part includes two first fins 22, and the number of the first fins 22 is not too large, which may result in the thickness of the first fins 22 being too small, which is not favorable for production and may be easily broken by impact during transportation and installation. In addition, the excessive number of the first fins 22 may cause the distance between the first fins 22 to be too small, which may affect convection.

In one embodiment, the width of the second heat sink member 21 is greater than the width of the first fins 22, and the length of the second heat sink member 21 is greater than or equal to the length of the first fins 22. The width of the second heat sink 21 is not too small, which is not favorable for transferring heat from the cylindrical base 1 to the first fins 22 on the outer periphery. In addition, in order to ensure the fracture strength, the second heat sink part 21 with larger width is used for connecting the first fins 22 and the cylindrical base 1, which is beneficial to reducing the fracture of the heat sink fins 2. In the processing process of the radiator section, the processing difficulty of the overlong part with the too small thickness is higher, the finished product is easy to deform, the width of the second radiating part 21 is properly increased, the length of the first fins 22 is properly controlled, and the production difficulty is also favorably reduced.

In one embodiment, the distance between the plurality of heat dissipation fins 2 and the connecting fins 3 is not less than the width of the second heat dissipation part 21, and the distance between the plurality of first fins 22 is not less than the width of the first fins 22. In order to ensure the heat dissipation effect, the distances between the heat dissipation fins 2 and the connecting fins 3 and between the two first fins 22 cannot be too small, otherwise, the amount of air passing through in unit time is too small, which results in poor heat dissipation effect.

Referring to fig. 3, in one embodiment, the connecting fins 3 include a third heat dissipating portion located at an outer side and a fourth heat dissipating portion 33 located at an inner side, the third heat dissipating portion includes a plurality of second fins 32, and inner ends of the plurality of second fins 32 are respectively connected to the fourth heat dissipating portion 33; the inner end of the fourth heat dissipation part 33 is connected with the cylindrical base 1; the fixing groove 31 is disposed at an outer end of the second fin 32. The connecting fin 3 is used for heat dissipation, and has a fixing function, and due to the limitation of space, the width of the second fin 32 is small, and the corresponding breaking strength is low, so that a plurality of second fins 32 are required to achieve sufficient connecting strength.

Further, the width of the fourth heat dissipation portion 33 is greater than the width of the second fin 32, and the length of the fourth heat dissipation portion 33 is not greater than one-half of the length of the heat dissipation fin 2. In order to ensure sufficient connection strength of the connection fin 3, the width of the fourth heat dissipation portion 33 is larger than the width of the second fins 32, and it is necessary to sufficiently connect the plurality of second fins 32. Since the width of the fourth heat dissipation portion 33 is larger and the specific surface area is correspondingly smallest, the length thereof is not suitable to be too long, otherwise, too much space is occupied, and the overall surface area is reduced.

Referring to fig. 3, in one embodiment, the width of the fourth heat dissipation portion 33 is three times or more than the width of the second fins 32, and at least one third fin 34 is further connected to the outer end of the fourth heat dissipation portion. The larger the width of the fourth heat dissipation portion 33 is, the higher the connection strength with the cylindrical base 1 is, and when the number of the second fins 32 connected to the outer end of the fourth heat dissipation portion is sufficient, the third fins 34 can be disposed in the extra space, so as to enhance the heat dissipation effect.
