[0032] In existing technologies, in-vehicle navigation devices are equipped with functional components such as motherboards, processors, graphics cards, and communication modules, all housed within a main unit casing. These electronic devices generate a significant amount of heat during operation, and the interior of a vehicle heats up rapidly after being exposed to sunlight, making the devices prone to overheating and potentially causing them to shut down. Currently, the heat dissipation structures of multimedia devices are ineffective and inefficient, affecting the normal operation of the equipment.

[0033] This utility model proposes a heat dissipation assembly.

[0034] Please see Figures 1 to 4 In one embodiment of this utility model, the heat dissipation assembly includes a radiator 100, a bracket 200, a first cooling fan 300, and a second cooling fan 400. The radiator 100 is provided with a receiving groove 110 and is also used to contact a heat source. The bracket 200 is disposed in the receiving groove 110 and is fixedly connected to the radiator 100. The first cooling fan 300 and the second cooling fan 400 are both disposed in the receiving groove 110 and are fixedly connected to the bracket 200 respectively. The first cooling fan 300 and the second cooling fan 400 are respectively disposed at both ends of the bracket 200. The first cooling fan 300 and the second cooling fan 400 blow air into the receiving groove 110 and form a heat dissipation airflow. The heat dissipation airflow exchanges heat with the radiator 100 and carries away the heat on the surface of the radiator 100.

[0035] In this embodiment, the radiator 100 is in contact with the heat source and exchanges heat with it. Heat is transferred from the heat source to the radiator 100, and a portion of the radiator 100 is recessed to form a receiving groove 110. A first cooling fan 300 and a second cooling fan 400 are located within the receiving groove 110 and blow air onto it. Since both fans blow air onto the radiator 100, the heat dissipation efficiency of the radiator 100 is improved, thereby enhancing the heat dissipation effect of the heat source. In specific implementation, both the first cooling fan 300 and the second cooling fan 400 are mounted on a bracket 200 located within the receiving groove 110 and installed on the radiator 100 using screws or other connectors. Compared to installing the cooling fans separately on the radiator 100, this simplifies the installation process and improves production efficiency. The first cooling fan 300 and the second cooling fan 400 are arranged side-by-side at opposite ends of the bracket 200, without interfering with each other. The cooling airflow flows from the receiving groove 110 along the radiator 100 and dissipates, carrying away the heat from the surface of the radiator 100, thereby achieving heat dissipation.

[0036] This utility model's technical solution involves a radiator 100 contacting a heat source, transferring heat from the heat source to the radiator 100. Two cooling fans, a first cooling fan 300 and a second cooling fan 400, blow air onto the radiator 100, carrying away heat from its surface and increasing the airflow, thereby improving the radiator 100's heat dissipation effect. Specifically, a receiving groove 110 is provided in the radiator 100, and the first cooling fan 300 and the second cooling fan 400 are installed in the receiving groove 110 using a bracket 200. The bracket 200 is fixedly connected to the radiator 100, simplifying the installation process of the two cooling fans and improving production efficiency. Both cooling fans blow air into the receiving groove 110, forming a cooling airflow. This airflow exchanges heat with the radiator 100, carrying away heat from its surface and improving the radiator 100's heat dissipation efficiency, thus enhancing the heat dissipation effect.

[0037] refer to Figure 2 and Figure 3 As shown, in one embodiment, the receiving slot 110 includes a first heat dissipation slot 111, a second heat dissipation slot 112 and a connecting slot 113. The connecting slot 113 connects the first heat dissipation slot 111 and the second heat dissipation slot 112. A first cooling fan 300 is disposed in the first heat dissipation slot 111, a second cooling fan 400 is disposed in the second heat dissipation slot 112, and a bracket 200 is disposed in the connecting slot 113.

[0038] Specifically, the first heat dissipation slot 111 and the second heat dissipation slot 112 are spaced apart and connected by a connecting slot 113. The first heat dissipation slot 111 accommodates the first cooling fan 300, and correspondingly, the second heat dissipation slot 112 accommodates the second cooling fan 400. The bracket 200 is located within the connecting slot 113 and extends to both the first and second heat dissipation slots 111 and 112 to facilitate the fixed installation of the first cooling fan 300 and the second cooling fan 400. Understandably, the cooling airflow can also flow through the connecting slot 113, improving the heat dissipation effect.

[0039] Furthermore, the radiator 100 is also provided with a connecting channel 114, the two ends of which are respectively connected to the first heat dissipation slot 111 and the second heat dissipation slot 112, and the heat dissipation airflow also flows into the connecting channel 114.

[0040] In this embodiment, the connecting channel 114 connects the first heat sink 111 and the second heat sink 112. The airflow generated by the first heat sink 300 and the second heat sink 400 also flows through the connecting channel 114, increasing the channels for heat dissipation airflow, enabling the heat dissipation airflow to be quickly dissipated and dispersed in multiple directions, avoiding the accumulation of heat dissipation airflow and improving the heat dissipation effect.

[0041] In a specific embodiment, two connecting channels 114 are provided, located on both sides of the connecting groove 113. Specifically, the connecting channels 114 extend in the same direction as the connecting groove 113. The first cooling fan 300 and the second cooling fan 400 rotate in the same direction. The two connecting channels 114 are located on both sides of the line connecting the two cooling fans. In this way, the two connecting channels 114 exchange airflow generated by the first cooling fan 300 and the second cooling fan 400. Of course, it can be understood that during the airflow exchange process, the airflow will also be dissipated through the radiator 100, so that the cooling airflow can flow over most of the surface of the radiator 100, thereby improving the heat dissipation effect of the radiator 100.

[0042] refer to Figure 4 As shown, in one embodiment, the bracket 200 includes a first mounting plate 210, a second mounting plate 220, and a connecting rod 230 connecting the first mounting plate 210 and the second mounting plate 220. The first mounting plate 210 is connected to the first cooling fan 300, and the second mounting plate 220 is connected to the second cooling fan 400. The first mounting plate 210 is provided with a cable management buckle 240, and the bottom surface of the receiving groove 110 is provided with an opening 115. The cable management buckle 240 is correspondingly provided with the opening 115. The electrical connection wires of the first cooling fan 300 and the second cooling fan 400 extend out of the heat sink 100 through the cable management buckle 240 and the opening 115.

[0043] In this embodiment, the first mounting plate 210 cooperates with the first cooling fan 300 to fix the first cooling fan 300 in place. Similarly, the second mounting plate 220 cooperates with the second cooling fan 400 to fix the second cooling fan 400 in place. Thus, the first cooling fan 300 and the second cooling fan 400 can be externally fixed to the bracket 200 first, and then installed in the receiving slot 110 via the bracket 200, facilitating the installation of the first cooling fan 300 and the second cooling fan 400. In specific implementation, the first mounting plate 210, the second mounting plate 220, and the connecting rod 230 are respectively fixed to the radiator 100 by screws. To improve the strength of the bracket 200, the first mounting plate 210, the second mounting plate 220, and the connecting rod 230 are integrally formed.

[0044] It should be noted that the first cooling fan 300 and the second cooling fan 400 are respectively connected to electrical connection wires. The electrical connection wire of the second cooling fan 400 extends along the connecting rod 230 to the cable management buckle 240 of the first mounting plate 210. After being limited and organized by the cable management buckle 240, it extends to the outside through the opening 115 of the receiving groove 110 to connect to the corresponding electrical components, so as to avoid the electrical connection wire interfering with the rotation of the cooling fan and causing danger.

[0045] In one embodiment, the bracket 200 is provided with a wire channel 250, through which the electrical connection wire of the second cooling fan 400 extends to the cable management clip 240. The electrical connection wire of the second cooling fan 400 extends along the wire channel 250 to avoid interference between the electrical connection wire and the cooling fan. It is understood that, in specific implementation, the wire channel 250 is also restricted from detaching from the wire channel 250 by installing clips.

[0046] In one embodiment, the cable clip 240 includes a fixing part and a limiting part 242. The fixing part is connected to the first mounting plate 210, and a slot 241 is provided between the limiting part 242 and the fixing part.

[0047] In the specific implementation process, the fixing part is fixedly connected to the first mounting plate 210, and the limiting part 242 is located on the side of the fixing part away from the first mounting plate 210, and a slot 241 is provided between the fixing part and the fixing part. The electrical connection wire extends from the first mounting plate 210 into the slot 241 to limit the displacement of the electrical connection wire. After the bracket 200 is installed on the heat sink 100, the slot 241 is opposite to the through opening 115, and the electrical connection wire extends from the slot 241 and the through opening 115 out of the heat sink 100. In addition, the cable management clip 240 is integrally formed with the first mounting plate 210 to improve the strength of the cable management clip 240.

[0048] In one embodiment, the radiator 100 includes a connecting portion 120 and a heat sink portion disposed on one side of the connecting portion 120. The side of the connecting portion 120 away from the heat sink portion is used to contact a heat source. The heat sink portion has a receiving groove 110. The bracket 200 is connected to the connecting portion 120.

[0049] Specifically, the radiator 100 is made of aluminum or aluminum alloy, which have good thermal conductivity; however, this embodiment is not limited to any particular material. The connecting portion 120 of the radiator 100 is used to contact the heat source and exchange heat with it, and further dissipates the heat to the outside air through the heat sink portion. The receiving groove 110 is provided on the heat sink portion. It is understood that the cooling airflow generated by the first cooling fan 300 and the second cooling fan 400 passes through the heat sink portion and carries away the heat from the surface of the heat sink portion.

[0050] Furthermore, the heat sink section includes multiple heat sinks 130 arranged side by side at intervals, with a heat dissipation channel 140 formed between two adjacent heat sinks 130, and the heat dissipation channel 140 communicating with the receiving groove 110.

[0051] In the specific implementation process, the first cooling fan 300 and the second cooling fan 400 are located inside the receiving groove 110 and blow air into the receiving groove 110 to form a cooling airflow. The cooling channel 140 is connected to the receiving groove 110. The cooling airflow enters the cooling channel 140 through the receiving groove 110 and flows along the cooling channel 140 to remove the heat from the surface of the heat sink 130. It can be understood that the cooling fans blow air towards the bottom and sides of the receiving groove 110, and the cooling airflow is directly dispersed and circulated through the cooling channel 140, avoiding stagnation in the receiving groove 110 and improving the heat dissipation effect. It should also be noted that the multiple heat sinks 130 are recessed to form the receiving groove 110. The bottom surface of the receiving groove 110 does not directly contact the connecting part 120 of the heat sink 100, and the bottom surface of the groove is also provided with a cooling channel 140, which can further improve the flow speed of the cooling airflow. In addition, the radiator 100 is also provided with a fixing seat, which is integrally formed with the connecting part 120 and extends into the receiving groove 110 to fix the bracket 200 and improve the stability of the bracket 200 installation.

[0052] In one embodiment, the extension direction of the heat dissipation channel 140 is perpendicular to the direction of the line connecting the first cooling fan 300 and the second cooling fan 400, so that the heat dissipation airflow can cover most of the heat sink 130 and flow through the heat dissipation channel 140. Furthermore, a connecting channel 114 and a connecting groove 113 are connected between the first heat dissipation slot 111 and the second heat dissipation slot 112, so that the heat dissipation airflow can also enter the corresponding heat dissipation channel 140 through the connecting channel 114 and the connecting groove 113, thereby allowing the heat dissipation airflow to cover most or even all of the heat sink 130, thereby improving the heat dissipation effect.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the inventive concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
