[0002] Airborne electronic equipment refers to various electronic equipment installed on aircraft, spacecraft, drones and other aircraft. With the continuous development of aerospace technology, airborne electronic equipment plays an increasingly important role in aircraft. Airborne electronic equipment can be divided into control equipment, navigation equipment, communication equipment, measurement equipment and detection equipment according to its function and purpose.

[0003] With the increase in the types and number of airborne recording devices, the working environment of airborne electronic equipment is becoming increasingly harsh, the power is getting higher and higher, and the heat dissipation problem is gradually becoming a bottleneck in its development.
[0004] Most of the current airborne electronic equipment chassis use ordinary straight fins as heat dissipation structures, but ordinary straight fins have low wind resistance, small heat dissipation area in limited space, small temperature difference between the air outlet temperature and the air inlet temperature, and can take away little heat, which is difficult to meet the heat dissipation requirements of high-heat modules in airborne electronic equipment. In addition, the current airborne electronic equipment chassis usually only has a single-layer air duct, and the heat dissipation capacity is limited. Summary of the invention
[0005] In view of this, the embodiment of the present application aims to provide a double-layer air duct heat dissipation chassis based on imitation honeycomb fins, which can greatly increase the heat dissipation area of the air duct, enhance the structural strength of the chassis, increase the utilization efficiency of the cooling air, and achieve efficient heat dissipation for multiple high-heat generating functional modules inside the airborne electronic equipment.
[0006] To achieve the above-mentioned purpose, the embodiment of the present application proposes a double-layer air duct heat dissipation chassis based on imitation honeycomb fins, comprising: imitation honeycomb fins (1), a front panel component (2), a box frame (3), a high-heat-generating functional module (4), a motherboard (5), a rear panel component (6), a fan (7), an air cavity (8), a first-layer imitation honeycomb air duct (9), a second-layer imitation honeycomb air duct (10) and an upper cover component (11), wherein an air outlet (12) is provided on the upper cover component (11); the motherboard (5) is mounted inside the box frame (3), the high-heat-generating functional module (4) is mounted on the motherboard (5) and is also placed inside the box frame (3), two imitation honeycomb fins (1) are respectively mounted on the left and right sides of the box frame (3), and the front panel component (2) is mounted on the box frame (3).

[0007] To achieve the above-mentioned purpose, an embodiment of the present application also proposes a chassis assembly method, which is suitable for assembling a double-layer duct heat dissipation chassis based on imitation honeycomb fins as described above, comprising the following steps: installing a flexible motherboard on the inside of the chassis frame by screws, inserting a high-heat-generating functional module on the motherboard and placing it on the inside of the chassis frame; brazing the first layer of imitation honeycomb duct, the second layer of imitation honeycomb duct and the upper cover component with an air outlet from bottom to top into one, and installing them on the top of the chassis frame by screws; installing two imitation honeycomb fins and the rear panel component on both sides and the rear side of the chassis frame respectively by screws, and then installing the fan on the rear panel component by screws; wherein, an air cavity is formed between the motherboard and the rear panel component, and the air outlet opened on the upper cover component faces the air cavity; installing the front panel component on the front side of the chassis frame by screws to complete the assembly of the chassis.
[0008] The embodiment of the present application proposes a double-layer air duct heat dissipation chassis based on imitation honeycomb fins. Two imitation honeycomb fins are installed on the left and right sides of the chassis frame, providing lateral heat dissipation conditions for high-heat function modules. Compared with ordinary straight-wing fins, the imitation honeycomb fins increase the heat dissipation area, increase the convective heat transfer coefficient, effectively improve the heat dissipation capacity of the chassis, and can also strengthen the strength of parts. The first layer of imitation honeycomb air duct and the second layer of imitation honeycomb air duct cooperate with the air cavity and the air outlet opened on the upper cover plate component to form a double-layer imitation honeycomb air duct. The fan is directly facing the high-heat function module, and blows high-pressure air into the chassis when the high-heat function module is working. The high-pressure air flows into the first layer of imitation honeycomb air duct through the air cavity, and then enters the second layer of imitation honeycomb air duct, and finally is discharged from the air outlet. Not only does it reduce the weight of the chassis to a certain extent, but it also improves the utilization efficiency of cold air as much as possible, and well realizes the efficient heat dissipation of high-heat function modules with high heat flux density, greatly improving the heat dissipation performance of airborne electronic equipment.

The front panel component, the motherboard and the rear panel component are all provided with openings for high-pressure air to pass through, which can quickly realize cold air circulation, further improve the utilization efficiency of cold air, and thus further improve the heat dissipation performance of the onboard electronic equipment.
[0012] In some optional embodiments, the front panel component (2) is a quick-release component, and two handles are also provided on the front panel component (2) for quickly moving the chassis. The high-heat function module is inserted on the motherboard in the front-to-back direction, and the front panel component is also equipped with a handle quick-release component. Such a design makes it only necessary to remove the front panel component when replacing or taking out the high-heat function module, which greatly reduces the complexity of the operation.
[0013] In some optional embodiments, the two imitation honeycomb fins (1), the front panel component (2), the box frame (3), the rear panel component (6), the first layer of imitation honeycomb air duct (9), the second layer of imitation honeycomb air duct (10) and the upper cover component (11) are all made of titanium alloy. The titanium alloy material is strong and reliable, and can effectively protect the high-heat generating functional modules and motherboard in the chassis.
[0014] In some optional embodiments, the motherboard (5) is made of polyimide and / or polyester film as a substrate. The motherboard made of polyimide and / or polyester film as a substrate is highly flexible and durable, has a high wiring density, is light in weight, is shock-resistant, and is easy to bend, and is very suitable for use in airborne electronic equipment.
[0015] In some optional embodiments, each high-heat-generating functional module (4) is provided with a thermal conductive paste on its surface for rapid heat transfer, and the thermal conductive paste is made of silicone. The thermal conductive paste can better cooperate with the simulated honeycomb fins, the double-layer simulated honeycomb air duct and the fan to help the onboard electronic equipment dissipate heat.

However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.
[0022] An embodiment of the present application proposes a double-layer duct heat dissipation chassis based on imitation honeycomb fins. The implementation details of the double-layer duct heat dissipation chassis based on imitation honeycomb fins proposed in this embodiment are specifically described below. The following content is only the implementation details provided for the convenience of understanding and is not necessary for the implementation of this solution.
[0023] The exploded diagram of the specific structure of a double-layer air duct heat dissipation chassis based on simulated honeycomb fins proposed in this embodiment can be shown as follows: Figure 1 As shown, it includes: an imitation honeycomb fin 1, a front panel component 2, a box frame 3, a high heat generating functional module 4, a motherboard 5, a rear panel component 6, a fan 7, an air cavity 8, a first layer of imitation honeycomb air duct 9, a second layer of imitation honeycomb air duct 10 and an upper cover component 11, and an air outlet 12 is provided on the upper cover component 11.
[0024] The motherboard 5 is installed inside the box frame 3, and multiple high-heat functional modules 4 are installed on the motherboard 5 and also placed inside the box frame 3. Two imitation honeycomb fins 1 are respectively installed on the left and right sides of the box frame 3, the front panel component 2 is installed on the front side of the box frame 3, and the rear panel component 6 is installed on the rear side of the box frame 3. An air cavity 8 is formed between the motherboard 5 and the rear panel component 6, and a fan 7 is installed on the rear panel component 6. The first layer of imitation honeycomb air duct 9, the second layer of imitation honeycomb air duct 10 and the upper cover component 11 are installed in sequence from bottom to top on the top of the box frame 3, and the air outlet 12 opened on the upper cover component 11 faces the air cavity 8.
[0025] The two imitation honeycomb fins 1 are used to provide lateral heat dissipation for the high-heat-generating functional module 4. The fan 7 is used to blow high-pressure air into the interior of the chassis when the high-heat-generating functional module 4 is working, and flows into the first-layer imitation honeycomb air duct 9 through the air cavity 8, and then enters the second-layer imitation honeycomb air duct 10, and is finally discharged from the air outlet 12, thereby taking the heat out of the chassis.
[0026] In one example, the structure of the simulated honeycomb fin is as follows Figure 2As shown, the hollow imitation honeycomb structure increases the heat dissipation area and the convection heat transfer coefficient compared to ordinary straight-wing fins, effectively improving the heat dissipation capacity of the chassis. At the same time, it can also enhance the strength of parts and provide protection for high-heat generating functional modules inside the chassis.
[0027] In one example, the first layer of imitation honeycomb air duct 9, the second layer of imitation honeycomb air duct 10 and the upper cover plate component 11 are brazed together and installed as a whole on the top of the box frame 3, and together with the two imitation honeycomb fins 1, the front panel component 2, the box frame 3 and the rear panel component 6 form the box body of the chassis.
[0028] It can be understood that the integrally brazed first-layer simulated honeycomb air duct, second-layer simulated honeycomb air duct and upper cover plate components are more convenient to disassemble and install, which effectively reduces the difficulty of assembling the chassis.

The design of the cold plate being attached to the guide rail effectively reduces the temperature of the guide rail and prolongs the service life of the double-layer simulated honeycomb air duct.

[0036] In one example, each high-heat functional module 4 is provided with a thermal conductive paste on its surface for rapid heat transfer, and the thermal conductive paste is made of silicone material. The thermal conductive paste can better cooperate with the simulated honeycomb fins, double-layer simulated honeycomb air ducts and fans to help the onboard electronic equipment dissipate heat.
[0037] In one example, each high-heat functional module 4 is also provided with a shock-absorbing filling block on its surface to buffer the vibration inside the chassis, and the shock-absorbing filling block is made of rubber. The shock-absorbing filling block can well fill the gaps between the high-heat functional modules, providing good vibration buffering protection for the high-heat functional modules.
[0038] In this embodiment, two imitation honeycomb fins are installed on the left and right sides of the box frame, providing the high-heat functional module with lateral heat dissipation conditions. Compared with ordinary straight-wing fins, the imitation honeycomb fins increase the heat dissipation area, increase the convective heat transfer coefficient, effectively improve the heat dissipation capacity of the chassis, and can also strengthen the strength of the parts. The first layer of imitation honeycomb air duct and the second layer of imitation honeycomb air duct cooperate with the air cavity and the air outlet opened on the upper cover plate component to form a double-layer imitation honeycomb air duct. The fan is directly facing the high-heat functional module and blows high-pressure air into the chassis when the high-heat functional module is working. The high-pressure air flows into the first layer of imitation honeycomb air duct through the air cavity, and then enters the second layer of imitation honeycomb air duct, and finally is discharged from the air outlet. It not only reduces the weight of the chassis to a certain extent, but also improves the utilization efficiency of cold air as much as possible, and well realizes the efficient heat dissipation of the high-heat functional module with high heat flux density, greatly improving the heat dissipation performance of airborne electronic equipment.
