Description

Technical Field

[0001] This utility model relates to the field of conductive heat dissipation technology, specifically to a component for conductive heat dissipation between LRM chassis modules. Background Technology

[0002] With the increasing integration and complexity of modern airborne equipment, higher requirements are placed on the size and heat dissipation performance of the chassis. Field replaceable modules (LRMs) are currently the most commonly used solution in electronic systems. Their modular and standardized features enable high reliability and rapid maintenance.

[0003] Due to electromagnetic compatibility and reliability considerations, LRM chassis generally employ natural heat dissipation. However, the chassis is an enclosed environment with poor airflow, relying primarily on conduction for heat dissipation. To ensure rapid module insertion and removal, significant gaps exist between modules. Since the electronic components within these modules are the primary heat sources, much of the heat cannot be effectively conducted to the chassis surface, resulting in poor heat dissipation and impacting overall processing power and speed. Summary of the Invention

[0004] The purpose of this invention is to provide a component for heat conduction and dissipation between LRM chassis modules, in order to solve the problem of poor heat dissipation of LRM modules in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A component for heat conduction between LRM chassis modules includes heat dissipation plates installed in the LRM chassis. The heat dissipation plates are arranged in pairs and parallel, with a tension spring between each pair of heat dissipation plates. The two ends of each pair of heat dissipation plates are movably installed in a sleeve plate, and each sleeve plate is fixed to a side plate of the LRM chassis. A movable wedge plate is installed on each sleeve plate. The inner side of the movable wedge plate has a wedge-shaped structure and is clamped between the pair of heat dissipation plates. The movable wedge plate is driven to move horizontally by a drive mechanism. By utilizing the wedge-shaped structure, the heat dissipation plates, and the tension spring, the pair of heat dissipation plates can move towards or away from each other, thereby achieving the contact or separation between the heat dissipation plates and the LRM modules.

[0007] Furthermore, the sleeve plate is a rectangular plate with a through groove machined in it. The end of the heat dissipation liner is assembled at one end of the through groove, and the movement distance of the heat dissipation liner is limited by the through groove. The movable wedge plate is assembled at the other end of the through groove, and its outer side extends out of the through groove for cooperation with the drive mechanism.

[0008] Furthermore, the tension springs are evenly distributed between a pair of heat dissipation plates.

[0009] Furthermore, the heat dissipation liner has limiting surfaces on both ends. When the movable wedge moves to contact the limiting surface, it cannot continue to move, thereby limiting the range of motion of the heat dissipation liner and the movable wedge.

[0010] Furthermore, limiting holes are machined at both ends of the heat dissipation liner, and fixing pins are used to pass through the limiting holes and the sleeve plate to fix it to the inner wall of the LRM chassis.

[0011] Furthermore, the drive mechanism uses a pin, and inclined surfaces are machined at the upper and lower ends of the outer side of the movable wedge plate, with the pin engaging with the inclined surfaces; when the pin is pressed down, the movable wedge plate moves horizontally under the action of the pin engaging with the inclined surfaces.

[0012] Furthermore, a thrust pin is installed at the end of the pin, and the thrust pin is threadedly connected to the pin.

[0013] Furthermore, a compression spring is installed between the thrust pin and the boss on the side plate of the LRM chassis.

[0014] Furthermore, the inner wall of the LRM chassis side panel is formed with a mounting groove that mates with the movable wedge plate, allowing the movable wedge plate to move horizontally within the mounting groove.

[0015] Compared with the prior art, this utility model has the following technical features:

[0016] This utility model has a simple structure. While allowing for quick disassembly of the modules, when the front panel is installed into the housing, the thrust pin drives the movable wedge, which in turn drives the heat dissipation liner, reducing the gap between modules and forming a complete heat transfer path. This results in a faster heat transfer rate and effectively improves the heat dissipation problem. Attached Figure Description

[0027] See appendix Figures 1 to 9 This utility model provides a component for heat conduction and dissipation between LRM chassis modules, including heat dissipation plates 6 installed in the LRM chassis. The heat dissipation plates 6 are arranged in pairs and parallel, and a tension spring 7 is arranged between each pair of heat dissipation plates 6. The two ends of each pair of heat dissipation plates 6 are respectively movably installed in a sleeve plate 5, and each sleeve plate 5 is fixed to the side plate 9 of the LRM chassis by screws. A movable wedge plate 4 is installed on each sleeve plate 5. The inner side of the movable wedge plate 4 has a wedge-shaped structure and is clamped between the pair of heat dissipation plates 6. The movable wedge plate 4 is driven to move horizontally by a drive mechanism. By utilizing the wedge-shaped structure and the cooperation of the heat dissipation plates 6 and the tension spring 7, the pair of heat dissipation plates 6 can move towards or away from each other, so as to achieve the contact or separation between the heat dissipation plates 6 and the LRM module.

[0028] In this solution, after the heat dissipation liner 6 is attached to the LRM module, the heat dissipation liner 6 contacts the sleeve 5, and the sleeve 5 contacts the side panel 9 of the chassis, thus forming a complete heat transfer path between the LRM module and the side panel 9 of the chassis. The heat generated inside the LRM module is quickly transferred to the chassis through this path.

[0029] In this design, the heat dissipation liner 6 is a rectangular plate, arranged in pairs with a gap between them; a movable wedge plate 4 is provided at each end of the heat dissipation liner 6, and a portion of the inner side of the movable wedge plate 4 is inserted between the heat dissipation liners 6. This inserted portion is designed as a wedge-shaped structure. (See [reference]). Figure 8 When the movable wedge 4 moves horizontally towards the heat dissipation liner 6, the wedge structure will cause the pair of heat dissipation liners 6 to move back to back and spread apart, at which point the tension spring 7 is stretched. The spread heat dissipation liners 6 will then contact the adjacent LRM module to establish a heat dissipation path. When disassembling the module, the movable wedge 4 can be driven to move horizontally outward (away from the heat dissipation liner 6). Under the elastic force of the tension spring 7, the heat dissipation liners 6 will move towards each other, reducing the gap and disengaging from the LRM module. This increases the gap around the LRM module, facilitating the insertion and removal of the LRM module.

[0030] In this plan, see Figure 9 The sleeve plate 5 is a rectangular plate with a through groove machined in it. The end of the heat dissipation liner 6 is assembled at one end of the through groove, and the movement distance of the heat dissipation liner 6 is limited by the through groove. The movable wedge plate 4 is assembled at the other end of the through groove, and its outer side extends out of the through groove for cooperation with the drive mechanism.

[0031] In this embodiment, the tension springs 7 are evenly arranged between a pair of heat dissipation plates 6, for example, a pair is arranged at the top and a pair at the bottom.

[0032] See Figure 7 The heat dissipation liner 6 has limiting surfaces on both sides. When the movable wedge 4 moves to contact the limiting surface, it cannot move further, thereby limiting the range of motion of the heat dissipation liner 6 and the movable wedge 4, and maintaining the integrity of the components.

[0033] See appendix Figure 1 and Figure 7 Limiting holes are machined at both ends of the heat dissipation liner 6. The fixing pin 8 passes through the limiting holes and the sleeve plate 5 and is fixed to the inner wall of the LRM chassis. The function of the limiting holes and the fixing pin 8 is to limit the movement direction of the heat dissipation liner 6, so that it can only move towards each other or away from each other, and cannot move horizontally, thus ensuring its working stability.

[0034] See appendix Figure 1 In this embodiment, the driving mechanism uses a pin 3, and inclined surfaces are machined on the upper and lower ends of the outer side of the movable wedge plate 4. The pin 3 cooperates with the inclined surfaces. When the pin 3 is pressed down, the movable wedge plate 4 moves horizontally under the action of the pin 3 and the inclined surfaces, thereby achieving the purpose of driving the movable wedge block 4 and then driving the heat dissipation liner 6 to move through the pin 3.

[0035] Furthermore, a thrust pin 1 is installed at the end of the pin 3, and the thrust pin 1 is threadedly connected to the pin 3. The threaded connection allows for easy adjustment of the effective range of motion of the pin 3, thus more widely adapting to changes in the LRM module gap.

[0036] To achieve self-recovery of position, a compression spring 2 is installed between the thrust pin and the boss on the LRM chassis side plate 9. The compression spring 2 allows the top of the thrust pin 1 to be pushed outward in the natural, unforced state, and in the compressed state, the thrust pin 1 is pressed down to push the movable wedge plate 4 to move horizontally, thereby increasing the gap of the heat dissipation liner 6.

[0037] See Figure 3The top of the thrust pin 1 contacts the front cover 10 of the LRM chassis. When the LRM chassis is fully installed, the thrust pin 1 is pressed down by the front cover 10, and the compression spring 2 is compressed. At this time, the movable wedge plate 4 is pushed by the pin 3, so that the heat dissipation liner 6 contacts the LRM module. When the front cover 10 is removed, the thrust pin 1 is pushed outward by the compression spring 2. Under the action of the tension spring 7, the gap of the heat dissipation liner 6 will shrink, and it will be separated from the contact with the LRM module, which facilitates the insertion and removal of the LRM module. This ensures that opening the front cover 10 does not affect the quick insertion and removal of the LRM module. After the LRM chassis is fully installed, a complete heat conduction path is formed from the LRM module to the LRM chassis side plate 9.

[0038] Optionally, the inner wall of the LRM chassis side panel 9 is formed with a mounting groove that mates with the movable wedge plate 4, allowing the movable wedge plate 4 to move horizontally within the groove and ensuring the stability of the movable wedge plate's movement.
