DETAILED DESCRIPTION

[0030] The specific implementation of the embodiment of the present application is further explained below in conjunction with the accompanying drawings of the embodiment of the present application.

[0031] Embodiment 1

[0032] See also Figure 1 and Figure 2 , an embodiment of the present application provides a heat dissipation device, comprising:

[0033] Bracket 10, heat dissipation module 20;

[0034] The bracket 10 is provided with a heat dissipation hole 101, and the heat dissipation hole 101 is used to dock with the side of the controller 30 provided with the hardware circuit 301, so that the side of the controller 30 provided with the hardware circuit 301 is located in the cavity 102 inside the bracket 10;

[0035] The heat dissipation module 20 is installed in the cavity 102 inside the bracket 10 . The heat dissipation module 20 is used to increase the flow speed of air in the cavity 102 inside the bracket 10 to dissipate heat for the controller 30 .

[0036] Specifically, the bracket 10 may be T-shaped, the heat dissipation hole 101 is arranged on the crossbeam at the upper end of the T-shaped bracket 10, and the interior of the crossbeam at the upper end of the T-shaped bracket 10 is a cavity 102, so that after the side of the controller 30 provided with the hardware circuit 301 is docked with the heat dissipation hole 101, the side of the controller 30 provided with the hardware circuit 301 is located in the cavity 102 inside the bracket 10, and the heat dissipation module 20 is installed in the cavity 102 inside the bracket 10. In this way, the heat dissipation module 20 directly dissipates the heat on the side of the controller 30 provided with the hardware circuit 301, thereby improving the heat dissipation efficiency of the heat dissipation device.

[0037] It should be noted that the heat dissipation hole 101 can pass through the cross beam at the upper end of the bracket 10, so that the controller 30 can be installed on both sides of the bracket 10, and the sides of the controllers 30 installed on both sides with the hardware circuit 301 can be located in the cavity 102 inside the bracket 10, so that more controllers 30 can be installed on the bracket 10 and the heat dissipation efficiency of the heat dissipation device is guaranteed.

[0038] The heat dissipation module 20 can be a fan, a hair dryer or other device that can increase the air flow rate. The heat dissipation module 20 works to increase the flow rate of air in the cavity 102 inside the bracket 10. The high-speed flowing air can take away the heat from the side of the controller 30 where the hardware circuit 301 is provided, thereby better dissipating the heat of the controller 30 and improving the heat dissipation efficiency of the heat dissipation device.

[0039] See also Figure 3 Optionally, in a specific implementation, the bracket 10 is further provided with an insertion slot 103 , and the insertion slot 103 is used to cooperate with the latch 302 of the controller 30 to install the controller 30 on the bracket 10 .

[0040] Specifically, the position of the insertion slot 103 can correspond to the position of the latch 302 of the controller 30. For example, if the latch 302 of the controller 30 is located on both sides of the side of the controller 30 where the hardware circuit 301 is provided, the insertion slot 103 can be correspondingly provided on both sides of the side of the heat dissipation hole 101 that docks the controller 30, and the position corresponds to the latch 302. In this way, the controller 30 can be more stably installed on the bracket 10, which helps to improve the stability of the heat dissipation device.

[0041] Optionally, in a specific implementation, the heat dissipation device further includes a sealing ring, which is used to seal the joint between the side of the controller 30 where the hardware circuit 301 is disposed and the heat dissipation hole 101 .

[0042] Specifically, the sealing ring can be a rubber sealing ring, so that the sealing performance of the sealing ring can be better. Of course, the sealing ring can also be made of other materials. This is just an exemplary description and does not mean that the present application is limited to this. The shape of the sealing ring matches the shape of the joint between the side of the controller 30 provided with the hardware circuit 301 and the heat dissipation hole 101. After the side of the controller 30 provided with the hardware circuit 301 is connected to the heat dissipation hole 101, the joint is sealed so that external dust and water cannot enter the cavity 102 inside the controller 30 and the bracket 10, thereby improving the reliability of the operation of the controller 30 and the heat dissipation module 20.

[0043] See also Figure 4 and Figure 5 , Optionally, in a specific implementation, the heat dissipation module 20 includes: a cover plate 201, at least one fan 202 and at least one isolation plate 203;

[0044] The fan 202 and the isolation plate 203 are installed below the cover plate 201 at intervals;

[0045] The fan 202 includes two blades, and the two blades form a right angle. The fan 202 is used to rotate in the cavity 102 inside the bracket 10 to increase the flow speed of the air in the cavity 102 inside the bracket 10.

[0046] Specifically, the fan 202 and the isolation plate 203 are installed at intervals below the cover plate 201. Both ends may be isolation plates 203, or both ends may be fans 202. Preferably, both ends are fans 202. For example, the heat dissipation module 20 includes four isolation plates 203 and five fans 202. The fans 202 and isolation plates 203 below the cover plate 201 can be installed smoothly as "fan, isolation plate 203, fan, isolation plate 203, fan, isolation plate 203, fan, isolation plate 203, fan". In this way, when different fans are suspended, the fans at both ends and other fans rotate, so that the cavity 102 inside the bracket 10 is divided into multiple air ducts, which meets the differentiated heat dissipation requirements of different controllers 30 and improves the heat dissipation efficiency of the heat dissipation device.

[0047] The two blades of the fan 202 are at a right angle, and when hovering parallel to the isolation plate 203, they can fill the gap between the isolation plates 203, and when hovering perpendicular to the isolation plates 203, they can divide the cavity 102 into two smaller cavities 102. When some of the fan 202 blades are hovering perpendicular to the isolation plate 203, some of the fan 202 blades are hovering parallel to the isolation plate 203, and other fans are rotating, the cavity 102 inside the bracket 10 is divided into multiple air ducts, which meets the differentiated heat dissipation requirements of different controllers 30 and improves the heat dissipation efficiency of the heat dissipation device.

[0048] The bracket 10 may be provided with fixing holes for fixing the heat dissipation module 20 . After the heat dissipation module 20 is inserted into the cavity 102 inside the bracket 10 , the heat dissipation module 20 may be fixed in the cavity 102 inside the bracket 10 through the fixing holes and bolts.

[0049] Optionally, in a specific implementation, the fan 202 further includes a motor and a mounting port, the motor is used to drive the fan 202 to rotate, and the mounting port is used to connect with the cover plate 201 to mount the fan 202 on the cover plate 201 .

[0050] Specifically, the motor can be installed at one end where the fan 202 is connected to the cover plate 201, and the mounting port is installed above the motor. In a preferred embodiment, the mounting port can be columnar and the side can be provided with threads. The corresponding cover plate 201 can be provided with matching threads so that the fan 202 can be fixed to the cover plate 201 by threads. This helps to improve the stability of the fan 202.

[0051] Optionally, in a specific implementation, a communication interface 211 is further provided on the cover plate 201 , and the communication interface 211 is electrically connected to the motor to control the fan 202 to turn on, turn off or hover at a preset angle.

[0052] Specifically, the communication interface 211 is electrically connected to at least three circuits of the motor, including power supply, ground supply and signal communication. The communication interface 211 can be a standard serial port (RS232), GPIB (General Purpose Interface Bus), Ethernet, USB (Universal Serial Bus), etc., and this application does not limit this.

[0055] A controller 30, a control module and a heat dissipation device as in the first embodiment;

[0057] The control module is used to control the fan 202 to turn on, turn off or hover at a preset angle.

[0058] Specifically, the control module can be connected to the communication interface 211 in the heat dissipation device to control the fan 202. The control module can be a programmable and executable device such as a microcomputer, a mobile phone, a single-chip microcomputer, etc., and this application does not limit this.

[0059] See also Figure 6 Optionally, in a specific embodiment, the control module divides the cavity 102 inside the bracket 10 into multiple air ducts by controlling some fans 202 to hover at an angle parallel to the isolation plate 203, controlling some fans 202 to hover at an angle perpendicular to the isolation plate 203, and controlling some fans 202 to turn on.

[0060] Specifically, for ease of explanation, Figure 4 The fans 202 and the isolation plates 203 are numbered from left to right in sequence: fan 1, isolation plate 2031, fan 2, isolation plate 2032, fan 3, isolation plate 2033, fan 4, isolation plate 2034, and fan 5. The control module can be set to at least four modes, which are described in detail below:

[0061] Mode 1

[0062] Control fans 2, 3, and 4 to suspend at an angle parallel to the isolation plate 203, control fans 1 and 5 to turn on and rotate in the same direction, and the cavity 102 inside the bracket 10 forms a circulating air duct, so that all controllers 30 can dissipate heat more evenly.

[0063] Mode 2

[0064] Control fan 2 and fan 4 to hover at an angle parallel to the isolation plate 203, and control fan 3 to hover at an angle perpendicular to the isolation plate 203. Control fan 1 and fan 5 to turn on and rotate in the same direction, so that the cavity 102 inside the bracket 10 forms two circulating air ducts, so that the heat dissipation of the controller 30 by fan 1 and the heat dissipation of the controller 30 by fan 5 do not interfere with each other. The control module can adjust fan 1 and fan 5 to different speeds as needed to meet the different heat dissipation requirements of the controller 30.

[0065] Mode 3

[0066] Control fan 2 and fan 4 to hover at an angle perpendicular to the isolation plate 203, control fan 1, fan 3 and fan 5 to turn on and rotate in the same direction, then the cavity 102 inside the bracket 10 forms three circulating air ducts, so that fans 1, fan 3 and fan 5 do not interfere with each other in the heat dissipation of the controller 30. The control module can adjust fans 1, fan 3 and fan 5 to different speeds as needed to meet the different heat dissipation requirements of the controller 30.

[0067] Mode 4

[0068] Control fan 3 and fan 4 to hover at an angle parallel to the isolation plate 203, and control fan 2 to hover at an angle perpendicular to the isolation plate 203. Control fan 1 and fan 5 to turn on and rotate in the same direction, so that the cavity 102 inside the bracket 10 forms two circulating air ducts, so that the heat dissipation of the controller 30 by fan 1 and the heat dissipation of the controller 30 by fan 5 do not interfere with each other. The control module can adjust fan 1 and fan 5 to different speeds as needed to meet the different heat dissipation requirements of the controller 30.

[0069] Of course, this is just an exemplary description, and different modes can be set according to needs to meet different heat dissipation requirements of controllers 30 in different positions. This application does not limit this.

[0070] Optionally, in a specific implementation, a latch 302 is provided on the controller 30 , and the latch 302 is used to cooperate with the insertion slot 103 to install the controller 30 on the bracket 10 .

[0071] Specifically, the position of the plug 302 of the controller 30 may correspond to the position of the insertion slot 103. For example, the insertion slot 103 may be arranged on both sides of the side of the heat dissipation hole 101 that docks the controller 30. Correspondingly, the plug 302 of the controller 30 may be arranged on both sides of the side of the controller 30 where the hardware circuit 301 is arranged, and the position corresponds to the plug 302. In this way, the controller 30 can be more stably mounted on the bracket 10, which helps to improve the stability of the heat dissipation device.

[0072] Optionally, in a specific implementation, the housing of the controller 30 is a plastic shell.

[0073] Specifically, after using a fan to dissipate heat from the controller 30 , the housing of the controller 30 can be downgraded to a lighter plastic housing, thereby reducing material costs.

[0074] The heat dissipation device and system provided in the embodiments of the present application cleverly utilize the internal cavity space of the bracket of the passenger compartment instrument tube beam, thereby achieving the installation of more controllers in the same instrument panel space and improving the heat dissipation performance of the bracket. It can also intelligently divide the cavity inside the bracket into multiple air ducts according to the heat dissipation requirements of controllers in different positions, thereby meeting the differentiated heat dissipation requirements of different controllers.
