[0029] Current research on automotive radiators mainly focuses on optimizing radiator structural design and improving material properties. However, existing research is relatively insufficient on the dynamic changes in radiator performance under extreme environments such as high temperature, high humidity, and high altitude, as well as the fatigue failure mechanism of radiators during long-term operation.

[0030] In view of this, the present invention provides a radiator 100, and Figures 1 to 3 are embodiments of the radiator 100 provided by the present invention.

[0031] Please refer to Figures 1 and 2. The radiator 100 includes a supporting body and a heat dissipation assembly. The supporting body includes at least one supporting column 1, which extends along a first direction and has its first end for connection with an external heat source. The heat dissipation assembly includes a plurality of heat dissipation fins 2, which are sleeved on the supporting body and spaced apart along the first direction. Each heat dissipation fin 2 has at least one heat dissipation hole. The supporting body and the heat dissipation fins 2 are diamond-aluminum alloy composite parts.

[0032] In this utility model, the supporting body and the heat sink 2 are both diamond-aluminum alloy composite parts, which have high thermal conductivity, with a thermal conductivity of over 400 W / (m·K), and high temperature resistance up to 600℃, without oxidation and peeling, thereby improving the reliability and durability of the heat sink 100 under complex working conditions and facilitating the lightweight design of the heat sink 100; the heat sink 2 has at least one heat dissipation hole to increase the heat dissipation area and further reduce weight; at the same time, the multiple heat sinks 2 are spaced apart to improve heat exchange efficiency, thereby improving heat dissipation efficiency.

[0033] It should be noted that the supporting body and the heat sink 2 are diamond-aluminum alloy composite parts, that is, the supporting body and the heat sink 2 are both made of diamond (10% content) and aluminum alloy materials. More specifically, the diamond and aluminum alloy materials are bonded at the micro interface through powder metallurgy process, which can solve the problem of the difference in thermal expansion coefficient of heterogeneous materials.

[0034] It should also be noted that, in one embodiment of this utility model, the supporting body and the heat sink 2 are welded together to ensure a high-strength connection between the two and improve reliability and durability.

[0035] It should also be noted that the external heat source is a car, a light-emitting diode, a printed circuit board, etc.

[0036] More specifically, in one embodiment of this utility model, the surface of the heat sink 2 is circular, with a diameter of 36mm and a thickness of 22.9mm.

[0037] Furthermore, referring to Figures 1 and 2, the surface of each heat sink 2 is arc-shaped, and its periphery is inclined towards the first end of the external heat source. Thus, by making the heat sink 2 arc-shaped, the heat dissipation area can be increased, and by making the heat sink 2 inclined towards the first end, airflow can be accelerated, thereby improving heat dissipation efficiency.

[0038] Furthermore, the inclination angle of the periphery of the heat sink 2 is greater than or equal to 50° and less than or equal to 52°. More specifically, in one embodiment of the present invention, the inclination angle of the periphery of the heat sink 2 is 50.14°.

[0039] Specifically, in this invention, the distance between any two adjacent heat sinks 2 is greater than or equal to 1 mm and less than or equal to 3 mm. More specifically, in one embodiment of this invention, the distance between any two adjacent heat sinks 2 is 3 mm.

[0040] Specifically, in this utility model, the number of support columns 1 is not limited; it can be one, two, three, or more.

[0041] More specifically, please refer to Figure 1. In one embodiment of this utility model, the support column 1 is provided and is located in the middle of the heat sink 2, and is hollow. In this way, not only can the weight be reduced, but the support column 1 is connected to the through hole, i.e. the heat sink 2, which is conducive to improving air flow and thus improving heat dissipation efficiency.

[0042] Further, referring to Figure 3, each of the heat sinks 2 has a first heat dissipation hole 21 and two second heat dissipation holes 22 passing through it. The first heat dissipation hole 21 is disposed corresponding to the support column 1, and the two second heat dissipation holes 22 are disposed at both ends of the first heat dissipation hole 21 in its radial direction. The portion of each second heat dissipation hole 22 near the support column 1 coincides with a portion of the periphery of the first heat dissipation hole 21. The portion of each heat sink 2 corresponding to the other portion of the periphery of the first heat dissipation hole 21 is fixedly connected to the support body. In this way, the heat dissipation area can be further increased, the airflow can be accelerated, the heat dissipation efficiency can be improved, and the weight can be reduced at the same time.

[0043] Further, referring to Figure 3, the diameter of the second heat dissipation hole 22 is smaller than the diameter of the first heat dissipation hole 21. More specifically, in one embodiment of this utility model, the diameter of the first heat dissipation hole 21 is 13mm, the diameter of each of the second heat dissipation holes 22 is 8mm, and the distance between the center of the first heat dissipation hole 21 and the center of the second heat dissipation hole 22 is 7.5mm.

[0044] Specifically, as shown in Figure 3, each heat sink 2 has multiple third heat dissipation holes 23 extending through it, and these holes 23 are spaced apart circumferentially along the heat sink 2. This further increases the heat dissipation area, improves heat dissipation efficiency, and reduces weight.

[0045] More specifically, please refer to Figure 3. Based on the embodiment described above, "each heat sink 2 has a first heat dissipation hole 21 and two second heat dissipation holes 22 passing through it. The first heat dissipation hole 21 is disposed corresponding to the support column 1, and the two second heat dissipation holes 22 are disposed at both ends of the first heat dissipation hole 21 in its radial direction. The portion of each second heat dissipation hole 22 near the support column 1 coincides with a portion of the periphery of the first heat dissipation hole 21; the portion of each heat sink 2 corresponding to another portion of the periphery of the first heat dissipation hole 21 is fixedly connected to the support body," four third heat dissipation holes 23 are provided. The four third heat dissipation holes 23 are symmetrically arranged around the first heat dissipation hole 21, and two of the four third heat dissipation holes 23 are disposed on both sides of one of the two second heat dissipation holes 22, while the other two of the four third heat dissipation holes 23 are disposed on both sides of the other of the two second heat dissipation holes 22. More specifically, the diameter of each third heat dissipation hole 23 is 6mm.

[0046] Specifically, as shown in Figure 3, each heat sink 2 has a plurality of fourth heat dissipation holes 24 on its periphery, and the plurality of fourth heat dissipation holes 24 are distributed at intervals along the circumference of the heat sink 2. In this way, the heat dissipation area can be further increased and the weight can be further reduced.

[0047] Further, referring to Figure 3, based on the embodiment described above, in which "each heat sink 2 is perforated by a first heat dissipation hole 21 and two second heat dissipation holes 22, the first heat dissipation hole 21 is disposed corresponding to the support column 1, the two second heat dissipation holes 22 are disposed at both ends of the first heat dissipation hole 21 in its radial direction, and the portion of each second heat dissipation hole 22 near the support column 1 coincides with a portion of the periphery of the first heat dissipation hole 21; the portion of each heat sink 2 corresponding to another portion of the periphery of the first heat dissipation hole 21 is fixedly connected to the support body; four third heat dissipation holes 23 are provided, the four third heat dissipation holes 23 are symmetrically arranged around the first heat dissipation hole 21, and two of the four third heat dissipation holes 23 are disposed on both sides of one of the two second heat dissipation holes 22, and the other two of the four third heat dissipation holes 23 are disposed on both sides of the other of the two second heat dissipation holes 22", four fourth heat dissipation holes 24 are provided, the four fourth heat dissipation holes 24 are distributed at intervals along the circumference of the heat sink 2, and are staggered from the four third heat dissipation holes 23; this is beneficial for uniform heat dissipation.

[0048] Specifically, referring to Figures 1 and 2, the heat sink 100 also includes a base 3, which is a diamond-aluminum alloy composite. One side of the base 3 is fixedly connected to the first end of the support body, and the other side is used for fixed connection to an external heat source. Thus, the external heat source is conducted through the base 3, and because it is made of diamond (10% content) and aluminum alloy, the density of the base 3 is 2.8 g / cm³.3 Compared to pure aluminum substrates, it reduces weight by 15%, further reducing the overall weight of the radiator 100 and achieving an overall lightweight design.

[0049] Furthermore, referring to Figure 1, the base 3 has at least one heat dissipation hole 31, which facilitates airflow, improves heat dissipation efficiency, and further reduces weight.

[0050] Furthermore, the base 3 is provided with a first heat dissipation through hole, two second heat dissipation through holes and a plurality of third heat dissipation through holes. The first heat dissipation through hole is provided corresponding to the first heat dissipation hole 21, the two second heat dissipation through holes are provided corresponding to the two second heat dissipation holes 22, and the plurality of third heat dissipation through holes are provided one-to-one with the plurality of third heat dissipation holes 23; this is conducive to further accelerating airflow and improving overall heat dissipation efficiency.

[0051] Specifically, referring to Figure 1, a portion of the periphery of the base 3 is recessed to form multiple heat dissipation recesses 32, which are spaced apart circumferentially along the base 3. This increases the heat dissipation area, improves heat dissipation efficiency, and reduces weight.

[0052] More specifically, the plurality of heat dissipation recesses 32 are provided in a one-to-one correspondence with the plurality of fourth heat dissipation holes 24.

[0053] Specifically, please refer to Figures 1 and 2. In the heat dissipation assembly, a heat sink 2 near the base 3 is provided with a heat dissipation gap between it and the base 3, which is beneficial to improve heat dissipation efficiency.

[0054] Furthermore, the heat dissipation gap is greater than or equal to 3 mm and less than or equal to 4 mm. More specifically, in one embodiment of this utility model, the heat dissipation gap is 3 mm.

[0055] The radiator 100 provided by this utility model has high heat dissipation efficiency, which can be improved by more than 50% compared with the traditional aluminum radiator 100. It is also resistant to high temperature, has high reliability and durability, and is lightweight, making it suitable for high-strength and lightweight applications such as aerospace.

[0056] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
