Technical Field

[0001] This utility model relates to the field of vehicle chassis technology, specifically to a heat dissipation structure for a VPX board test chassis. Background Technology

[0002] Chinese utility model patent application number 202010972812.8—a VPX vehicle chassis—includes a chassis body, with front and rear plug-in card module slots designed inside the chassis body; front plug-in card modules are installed in the front plug-in card slots, and rear plug-in card modules are installed in the rear plug-in card module slots; both the front and rear plug-in card module slots are uniformly set according to the VPX standard; the front and rear plug-in card modules have a uniform plug-in structure according to the standard; a cooling fan is correspondingly provided on the chassis body, and ventilation waveguide plates are also provided on the air inlet and air outlet of the chassis; a shielding glass is also provided on the front panel of the chassis; and all electrical connection ports on the chassis are sealed with conductive rubber rings.

[0003] The above-mentioned patented vehicle chassis structure design is highly integrated, unified, and standardized, offering advantages such as rapid assembly and disassembly of circuit boards and modules, high integration, standardized structure, and interchangeability. However, when the middle circuit board module is used at full power in a test machine, the cool air entering the chassis is still drawn by the fans on both sides to cool the circuit boards on the sides. This results in the middle circuit board module drawing in slightly warmer air, leading to poorer heat dissipation compared to the circuit boards on the sides. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a heat dissipation structure for a VPX board testing chassis. The technical problem it solves is that existing structures have poor airflow, and the central section where the board modules are inserted draws in warmer air, resulting in insufficient heat dissipation. To solve the above-mentioned technical problems, the technical solution adopted by this utility model is:

[0005] A heat dissipation structure for a VPX board test chassis, characterized in that it includes:

[0006] The enclosure is composed of a front panel, a rear panel, a left panel, a right panel, a top panel, and a bottom panel. The front panel, left panel, and right panel all have air inlets, while the rear panel has a heat dissipation vent.

[0007] The air intake duct is located between the left and right panels, and both ends of the air intake duct are connected to the air inlet.

[0008] The exhaust vent is located in the middle of the air inlet duct.

[0009] The upper and lower insert plates are installed inside the box. Both the upper and lower insert plates are provided with side ribs. Ventilation openings A are opened on the side ribs. The ventilation openings A on the lower insert plate are partially covered by the exhaust port.

[0010] The sealing plate is set at a predetermined height above the upper insert plate, and the sealing plate is provided with several ventilation openings B at intervals;

[0011] The fan is connected to the sealing plate, and the fan inlet is connected to the ventilation outlet B.

[0012] The exhaust duct is installed on the sealing plate, and the air outlet of each fan is connected to the heat dissipation port through an exhaust duct.

[0016] Furthermore, several partitions are fixedly installed between the sealing plate and the upper plate, and the adjacent partitions, sealing plate, and upper plate form an exhaust duct.

[0017] Furthermore, the air inlet is covered with a dustproof net.

[0018] The beneficial effects of this utility model are as follows:

[0019] By setting up independent air intake ducts, the fans in the middle section directly introduce outside air from the air intake vents into the middle section, reducing the competition between the fans on both sides, ensuring the heat dissipation effect of the middle plug-in card module, and improving heat dissipation efficiency; and each fan is equipped with an exhaust duct, optimizing the heat dissipation path, reducing hot air cross-interference, and ensuring that heat in high-temperature areas is quickly discharged.

[0020] Air inlets are located on the front, left, and right panels to ensure efficient entry of external cold air; heat dissipation vents are located on the upper part of the rear panel, forming a smooth flow channel with the air inlets to accelerate the exhaust of hot air.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0029] A VPX board test chassis heat dissipation structure includes a chassis body, which is formed by a front panel 1, a rear panel 2, a left panel 3, a right panel 4, an upper panel 5, and a lower panel 6. The front panel 1, left panel 3, and right panel 4 each have air inlets 7, and the rear panel 2 has a heat dissipation vent 8 located at the upper part of the rear panel, forming a smooth flow channel with the air inlets to accelerate the exhaust of hot air. An air intake duct 9 is provided between the left panel 3 and the right panel 4 to ensure efficient intake of external cold air. Both ends of the air intake duct 9 are connected to the air inlets 7, and an exhaust vent 10 is provided in the middle of the air intake duct 9. An upper insert plate 11 and a lower insert plate 12 are provided inside the chassis. The upper and lower insert plates 11 and 12 are both provided with side ribs 13. Two adjacent side ribs 13 form a slot for placing the insert card module. The side ribs 13 are provided with ventilation openings A14. Part of the ventilation openings A14 of the lower insert plate 12 are covered by the exhaust vent 10, so that external air can enter the ventilation openings A14 covered by the exhaust vent 10 through the air inlet duct 9. By setting an independent air inlet duct 9, the fan 17 in the middle part directly introduces the outside air from the air inlet 7 into the middle part, reducing the competition between the fans 17 on both sides, ensuring the heat dissipation effect of the middle insert card module, and improving the heat dissipation efficiency.

[0030] A sealing plate 15 is installed inside the chassis at the top of the upper plate 11. The sealing plate 15 and the upper plate 11 are at a predetermined height. The sealing plate 15 is provided with several ventilation openings B16 at intervals. A fan 17 is installed at the sealing plate 15 at the ventilation openings B16. The air inlet 7 of the fan 17 is connected to the ventilation opening B16. An exhaust duct 18 is also provided on the sealing plate 15. The air outlet of each fan 17 is connected to the heat dissipation opening 8 through an exhaust duct 18. Several partitions 20 are fixedly installed between the sealing plate 15 and the upper plate 5. Adjacent partitions 20, the sealing plate 15, and the upper plate 5 form an exhaust duct 18. Each fan 17 is provided with an exhaust duct 18 to optimize the heat dissipation path, reduce the cross interference of hot air, and ensure that the heat in the high-temperature area is quickly discharged.

[0031] It should be noted that the distance between the air inlet duct 9 and the lower insert plate 12 is 0.5 cm. In other embodiments, it can also be 1 cm, 2 cm, or 3 cm to prevent the side wall of the air inlet duct 9 from blocking the ventilation opening A14.

[0032] It should be noted that a frame 19 is provided between the air inlet duct 9 and the lower insert plate 12. The frame 19 is fixedly connected to the air inlet duct 9 and is connected to the exhaust port 10, ensuring that the air in the air inlet duct 9 directly enters the middle insert plate module through the ventilation port A14 for heat dissipation.

[0033] Specifically, fan 17 is a blower cooling fan.

[0034] It should be noted that both the air inlet 7 and the heat dissipation vent 8 are covered with dust filters. The dust filters can effectively block dust in the air and reduce the impact of dust accumulation inside the chassis on the equipment.

[0035] The working principle and process of this utility model are as follows:

[0036] When the VPX board chassis is working, the fan 17 is started. Part of the air outside the chassis enters directly into the interior through the air inlet 7, and another part enters the middle of the chassis through the air inlet duct 9. Then, it passes through the ventilation port A14 of the lower plug-in board 12 and enters the space between two adjacent plug-in board modules. Then, it enters the space between the sealing plate 15 and the upper plug-in board 11 through the ventilation port A14 of the upper plug-in board 11. It enters the fan 17 through the ventilation port B16, enters the exhaust duct 18 through the fan 17, and is then discharged through the heat dissipation port 8.
