[0035] The present invention proposes a heat dissipation structure, a satellite communication device and a vehicle, which can at least solve the technical problems of the existing heat dissipation structure being complex in structure and large in size. The present invention is specifically implemented by the following technical solution.

[0036] Combine Figures 1 to 7 As shown, a heat dissipation structure provided in an embodiment of this specification includes:

[0037] Substrate 1, the first side surface of the substrate 1 is used for mounting the antenna array surface;

[0038] a heat conducting member 2 connected to the first side surface of the substrate 1;

[0039] The base plate 1 and the heat conducting member 2 are both used for connecting to the vehicle body.

[0040] The vehicle-mounted antenna can be a device that receives high-frequency radio waves emitted by a transmitter and transmits them to a receiver of a car radio, car phone or radio navigation equipment to demodulate the carrier; the antenna array of the vehicle-mounted antenna includes a transmitting array 9 and a receiving array 8.

[0041] In the embodiments of this specification, the antenna array of the vehicle-mounted antenna generates heat during operation. The heat from the antenna array can be transferred to the substrate 1 and then to the heat conductor 2. The heat conductor 2 can further dissipate the heat, thereby increasing the heat dissipation area of ​​the heat dissipation structure and improving the heat dissipation effect. The heat conductor 2 and the antenna array are arranged on the same side of the substrate, which facilitates the heat dissipation from the antenna array to the heat conductor 2 through the substrate 1. The substrate 1 and the heat conductor 2 can both be connected to the vehicle body, thereby placing the heat dissipation structure as a whole on the vehicle body roof 7. This not only facilitates the antenna array to transmit and receive signals, but also facilitates the heat dissipation structure to dissipate heat to the inside and outside of the vehicle in a timely and rapid manner. For example, the substrate 1 and the heat conductor 2 can both be connected to the vehicle body roof 7. The installation location of the substrate 1 and the heat conductor 2 on the vehicle body is not limited to the vehicle body roof 7; any location on the vehicle body will suffice.

[0042] The heat dissipation structure provided in the embodiments of this specification has a simple structure, does not require a heat dissipation fan, has no complicated connection structure and connection relationship, occupies a small volume, has a low manufacturing cost, and has a good heat dissipation effect.

[0043] In a possible implementation, the heat conductor 2 includes a plate body 21 and a connecting block 22 , wherein a first end of the connecting block 22 is connected to the first side surface of the substrate 1 , and a second end of the connecting block 22 is connected to the plate body 21 .

[0044] In the embodiment of this specification, the first side surface of the substrate 1 can be the outer side surface, and the first side surface of the substrate 1 can face the outside of the vehicle; the connecting block 22 is arranged between the plate body 21 and the substrate 1, and the connecting block 22 can conduct the heat of the substrate 1 to the plate body 21, and the plate body 21 can dissipate the heat to other spaces, thereby achieving the technical effect of quickly dissipating the heat of the antenna array surface and avoiding overheating of the antenna array surface.

[0045] Because the connecting block 22 is connected to the first side of the base plate 1, the plate body 21 can face the exterior of the vehicle. This allows the plate body 21 to dissipate most of the heat to the exterior, minimizing the impact on the interior of the vehicle. In this embodiment, the first end of the connecting block 22 is positioned opposite the second end of the connecting block 22, and the first side of the base plate 1 is positioned opposite the second side of the base plate 1. In this embodiment, the heat conductor 2 is integrally formed.

[0046] In one possible implementation, the plate body 21 may be a curved plate, and the connecting block 22 may be a strip-shaped connecting block. The first end of the connecting block 22 may be adapted to fit within the curved plate body 21, and the second end of the connecting block 22 may be adapted to fit within the first side surface of the substrate 1. The length of the connecting block 22 may be equal to or greater than the length of the substrate 1. This can increase the contact area between the connecting block 22 and the substrate 1 without hindering the placement of the antenna array, thereby improving the heat transfer efficiency from the substrate 1 to the heat conducting element 2 and increasing the heat dissipation rate.

[0047] In a possible implementation, the heat dissipation structure further includes a heat conducting layer, which is disposed between the substrate 1 and the connecting block 22 .

[0048] In the embodiment of this specification, the heat conducting layer can assist in heat conduction, facilitate heat transfer from the substrate 1 to the connecting block 22, improve the heat transfer rate, and prevent the substrate 1 from overheating and causing adverse effects on the antenna array. The heat conducting layer can be a heat conducting silicone sheet.

[0049] In a possible implementation, the heat dissipation structure further includes screws, and the substrate 1 is connected to the connection block 22 via the screws.

[0050] In the embodiment of this specification, the substrate 1 and the connecting block 22 are connected by screws; the screws can be nailed in from the second side of the substrate 1, pass through the substrate 1 and be inserted into the connecting block 22, and the connection structure is firm and reliable.

[0051] In a possible implementation, the heat conducting member 2 further includes reinforcing ribs 23 , and the reinforcing ribs 23 are respectively connected to the connecting block 22 and the plate body 21 .

[0052] In the embodiment of this specification, there can be multiple reinforcing ribs 23, and the reinforcing ribs 23 can improve the structural strength of the heat conducting member 2. The first side of the reinforcing rib 23 can be connected to the plate body 21, and the second side of the reinforcing rib 23 can be connected to the connecting block 22. The first side of the reinforcing rib 23 and the second side of the reinforcing rib 23 can be arranged adjacent to each other.

[0053] In a possible implementation, the heat dissipation structure further includes a reinforcing plate 5 , which is connected to the second side surface of the substrate 1 .

[0054] In the embodiment of this specification, the second side surface of the base plate 1 may face the interior of the vehicle, and the reinforcing plate 5 may improve the structural strength of the base plate 1 .

[0055] In a possible implementation, the substrate 1 and the heat conducting element 2 are both made of aluminum.

[0056] In the embodiments of this specification, aluminum can be used as the material for substrate 1 and thermal conductor 2, providing them with excellent thermal conductivity and structural strength. They can be manufactured using an aluminum casting process. The materials for substrate 1 and thermal conductor 2 are not limited to these materials and can be any material with excellent thermal conductivity and heat dissipation.

[0057] In one possible implementation, the base plate 1 is provided with multiple connecting plates 10, each of which has a first connecting hole and a second connecting hole 12. The first connecting hole is provided with a first bolt 11, which can be connected to the vehicle body roof 7; the second connecting hole 12 is provided with a second bolt, which can be connected to the outer cover 6. The outer cover 6 can be installed outside the base plate 1 to protect the base plate 1. The base plate 1 is also provided with a control sub-unit 13, which has a connection port 14.

[0058] In a possible implementation, the heat conducting member 2 is provided with a plurality of positioning pins 24 . The positioning pins 24 may be provided on a side of the plate 21 close to the connecting block 22 . The positioning pins 24 may be connected to the vehicle body roof 7 .

[0059] The embodiments of this specification can be applied to the arrangement of automotive satellite radars, and the heat generated during the use of the satellite radar can be dissipated through the cast aluminum heat conducting plate (heat conducting member 2); by adopting the cast aluminum heat conducting plate, the number of cooling components such as cooling fans can be reduced, the space utilization rate can be improved, and costs can be saved. The heat emitted by the satellite antenna can be conducted to the cast aluminum heat conducting plate, which dissipates the heat inside and outside the vehicle. The heat emitted outside the vehicle directly enters the atmosphere, and the heat emitted inside the vehicle will enter the vehicle along the gaps in the ceiling and will not affect the passengers. The cast aluminum heat conducting plate has a large heat dissipation area, good heat dissipation effect, and high efficiency. Using a cast aluminum heat conducting plate for heat dissipation makes installation simpler and more efficient, and reduces the complex installation process of cooling components such as cooling fans.
