Description
Technical Field
[0001] The utility model belongs to the technical field of intersection road traffic, and in particular relates to a heat dissipation structure of an electronic equipment. Background Art
[0002] Since outdoor electronic equipment is exposed to sunlight for a long time, and the heat generated by its own components continues to accumulate, the heat dissipation design of outdoor electronic equipment is particularly important. The heat dissipation efficiency of electronic equipment is closely related to the processing accuracy and mutual clearance of heat dissipation components. The accuracy of general processing methods and assembly accuracy are difficult to meet the needs of good heat dissipation. In addition, most of the existing electronic equipment has a rigid structure inside, and the heat dissipation structure is also a hard support, which leads to the problem of poor thermal conductivity. Therefore, a flexible bracket heat dissipation structure that can compensate for processing errors and assembly errors is urgently needed. Utility Model Content
[0003] The purpose of the utility model is to provide an electronic device heat dissipation structure to solve the problems of low assembly efficiency and low thermal conductivity due to the processing and assembly precision of the existing electronic device heat dissipation structure in the background technology and the fact that most of the internal structures of the equipment are rigid, thereby improving the durability of the device.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A heat dissipation structure for an electronic device comprises: a floating bracket and a fixed bracket; the fixed bracket is arranged on a device base, a floating bracket spring seat and a fixed bracket spring seat are respectively arranged at the bottom of the floating bracket and the top of the fixed bracket, a spring is sleeved between the floating bracket spring seat and the fixed bracket spring seat, the lower end of the spring is fixed in the fixed bracket spring seat, and the upper end of the spring is fixed in the floating bracket spring seat, so that the floating bracket is floated and installed on the fixed bracket frame.
[0006] Furthermore, a guide portion is provided on the peripheral side of the floating bracket, and a floating guide hole is provided on the guide portion, and the floating guide hole is connected to a guide bolt installation position provided on the fixed bracket through a guide bolt.
[0007] Furthermore, the floating guide hole is opened in the vertical direction, so that the floating bracket can move up and down relative to the fixed bracket.
[0008] Furthermore, a plurality of safety columns are fixedly installed on the top of the floating bracket, the heat dissipation element is passed through the safety columns, the top of the safety columns supports the heat sink, and a heat conductive block is arranged between the heat sink and the heat dissipation element for conducting heat away from the heat dissipation element.
[0009] Furthermore, a heat dissipation element installation position is provided at the connection between the safety column and the floating bracket, so that the heat sink and the floating bracket maintain a distance.
[0010] Furthermore, the safety columns are arranged at the four corners of the floating support.
[0011] Furthermore, the heat conductive block is closely attached to the heat source of the heat dissipation element.
[0012] Furthermore, the device base is a device housing or a fixing base.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] (1) The utility model arranges a floating bracket spring seat and a fixed bracket spring seat between the floating bracket and the fixed bracket respectively, and sets the upper and lower ends of the spring in the two spring seats, so that the floating bracket is floatingly installed on the fixed bracket. At this time, since the springs are independent of each other and the floating bracket has a certain amount of movable margin in the vertical direction, the size gap error and the shape and position errors of the top surface of the heat conduction block and the bottom surface of the heat sink arranged in the bracket caused by their own defects can be automatically compensated, and the two surfaces are pressed against each other, which solves the problem of poor heat conduction and heat dissipation of the traditional rigid structure and improves the efficiency of heat conduction and transfer.
[0015] (2) The utility model provides a guide portion on the peripheral side of the floating bracket, and a floating guide hole on the guide portion, and connects the floating bracket and the fixed bracket together through the action of a guide bolt. Since the floating guide hole is opened in the vertical direction, the floating bracket can move up and down relative to the fixed bracket, further limiting the range of movement of the floating bracket and ensuring the heat dissipation effect.

The floating guide hole 5 . 3 is connected to a guide bolt installation position 7 . 2 provided on the fixed bracket 7 through a guide bolt 6 .
[0025] In this embodiment, the floating guide hole 5 . 3 is opened in the vertical direction, so that the floating bracket 5 can move up and down relative to the fixed bracket 7 .
[0026] In this embodiment, a plurality of safety columns 4 are fixedly installed on the top of the floating bracket 5, and the heat dissipation element 3 is passed through the safety columns 4. The top of the safety columns 4 supports the heat sink 1, and a heat conductive block 2 is arranged between the heat sink 1 and the heat dissipation element 3 for conducting heat out of the heat dissipation element 3.
[0027] In this embodiment, a heat dissipation element installation position 5.2 is provided at the connection between the safety column 4 and the floating bracket 5, so that the heat sink 1 and the floating bracket 5 maintain a distance.

[0032] During installation, first fix the fixing bracket 7 on the equipment base 8.
[0033] Then, the safety column 4 is used to install the heat dissipation component 3 on the heat dissipation component installation position 5.2 of the floating bracket 5. Then, the heat conduction block 2 is installed on the heat dissipation component 3, close to the heat source 3.1.
