Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp radiators, in particular to an ultra-thin lamp radiator. Background Art

[0002] In the field of automotive lighting, the lamp radiator is an important component for internal heat dissipation of the lamp, and is mainly composed of a base, heat dissipation fins and fans. However, as far as the current lamp radiator is concerned, its fan is generally located on the top or outside of the heat sink, which makes it difficult to quickly blow away the heat and achieve rapid cooling. The heat dissipation efficiency and performance are not ideal; at the same time, the fan arrangement of the traditional combination of the radiator makes the lamp radiator thicker as a whole, requiring a larger installation space, which is not conducive to the installation of the lamp radiator and its use in the new flat lamp. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an ultra-thin lamp radiator, which combines the cooling fins with the fan in a compact arrangement, is thinner as a whole, occupies less space, and has higher heat dissipation efficiency and performance.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] An ultra-thin lamp radiator comprises a radiator base and a fan assembly. A plurality of circumferentially arranged first radiating fins are arranged on the upper side of the radiator base, and a sink is formed at one end where the plurality of first radiating fins gather together. The fan assembly is arranged on the upper side of the radiator base and is limitedly embedded in the sink.

[0006] Furthermore, a plurality of ventilation slots are provided on the radiator base.

[0007] Furthermore, a notch is formed at one end of the first heat dissipation fin close to the fan assembly, and a plurality of notches together form a sink.

[0008] Furthermore, at least one of the first heat dissipation fins is extended to form a card plate at one end close to the fan assembly, and a card slot corresponding to the card plate is opened on the outer side of the fan assembly, and the card plate is limitedly engaged in the card slot.

[0009] Furthermore, the first heat dissipating fins and the heat sink base are an integrated structure.

[0010] Furthermore, a plurality of second heat dissipating fins are arranged on the bottom side of the heat sink base.

[0011] Furthermore, an LED module and an optical component are also arranged on the bottom side of the heat sink substrate.

[0012] By adopting the above technical solution, the utility model has the following beneficial effects:

[0013] 1. The utility model designs all the first heat dissipation fins to be arranged in a circumferentially gathered manner, which can reduce the occupied space as much as possible, and arrange enough heat dissipation fins in a limited space to improve the heat dissipation performance. At the same time, a sink is designed in the center of the gathered first heat dissipation fins to limit the placement of the fan assembly. On the one hand, the embedded arrangement of the fan assembly does not exceed the height of the first heat dissipation fins, thereby reducing the thickness of the overall structure, reducing the occupied space, and facilitating the installation of the lamp radiator and the use in the new flat car lamp; on the other hand, the fan assembly can be used to directly blow to all the first heat dissipation fins, and the heat is blown outward from the center of the gathered first heat dissipation fins, which is conducive to rapid cooling and improving heat dissipation efficiency and performance.

[0014] 2. The utility model provides ventilation slots on the radiator base, which is beneficial to air circulation when the fan blows air, and further improves the heat dissipation efficiency and performance.

[0015] 3. The utility model provides a second heat dissipation fin on the bottom side of the radiator base, which is beneficial to increase the overall heat dissipation area, thereby improving the heat dissipation performance and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0021] like Figure 1-3As shown, in this embodiment, an ultra-thin lamp heat sink is provided, which is mainly composed of a heat sink base 1, a first heat dissipation fin 2, a fan assembly 4, an LED module 8 and an optical assembly 9. The LED module 8 and the optical assembly 9 are installed on the bottom side of the heat sink base 1. A plurality of first heat dissipation fins 2 are arranged on the upper side of the heat sink base 1, and all the first heat dissipation fins 2 are arranged circumferentially and distributed in a clustered shape. The ends of the plurality of first heat dissipation fins 2 that are gathered together form a sink 5, that is, a notch is provided at one end of the first heat dissipation fin 2 close to the center, and the plurality of notches together form a sink 5. The shape of the sink 5 is similar to that of the fan assembly 4. The fan assembly 4 is a box-shaped structure with a bracket, which is fixed and locked to the upper side of the heat sink base 1 by screws and is limitedly embedded in the sink 5, so that the upper surface of the fan assembly 4 can not exceed the height of the first heat dissipation fin 2.

[0022] In the above design, this embodiment designs all the first heat dissipation fins 2 to be arranged in a circumferentially gathered manner, which can reduce the occupied space as much as possible, and arrange enough heat dissipation fins in a limited space to improve the heat dissipation performance. At the same time, a sink 5 is designed to be formed in the center of the gathered first heat dissipation fins 2 to limit the placement of the fan assembly 4. On the one hand, the fan assembly 4 can be embedded and arranged so as not to exceed the height of the first heat dissipation fins 2, thereby reducing the thickness of the overall structure and the occupied space, which is conducive to the installation of the lamp radiator and the use in the new flat car lamp; on the other hand, the fan assembly 4 can be used to directly blow to all the first heat dissipation fins 2, and the heat is blown outward from the center of the gathered first heat dissipation fins 2, which is conducive to rapid cooling and improving heat dissipation efficiency and performance.

[0023] In order to further improve the heat dissipation efficiency and performance, the present embodiment has a plurality of ventilation slots 10 on the heat sink base 1, which can enhance the air circulation when the fan blows, thereby improving the heat dissipation efficiency and performance. Of course, the first heat dissipation fins 2 and the heat sink base 1 in the present embodiment are an integrated structure, which can also improve the heat dissipation performance. In addition, a plurality of second heat dissipation fins 3 are arranged on the bottom side of the heat sink base 1, which can increase the overall heat dissipation area, thereby improving the heat dissipation performance and efficiency.

[0024] In order to improve the assembly stability of the fan assembly 4, in this embodiment, the three first heat dissipation fins 2 are designed to extend at one end close to the fan assembly 4 to form a clamping plate 6, and three clamping grooves 7 corresponding to the clamping plate 6 are opened on the outside of the fan assembly 4. The clamping plate 6 parts of the three first heat dissipation fins 2 are respectively limited and clamped in the three clamping grooves 7 of the fan assembly 4, thereby forming a better stabilizing effect on the fan assembly 4 and reducing the large-scale vibration during its operation.
