Description

Technical Field

[0001] The utility model belongs to the technical field of chassis, and in particular relates to a high-density blade reinforced chassis used in a high-humidity and high-heat environment. Background Art

[0002] With the development of military computers, the performance requirements for computers are gradually increasing, and their environmental adaptability requirements are also getting higher and higher. For example, ship-borne reinforced computers are required to meet harsh military environmental indicators such as fifteen cycles of alternating humidity and heat, acid salt spray, mold level 1, and rain.

[0003] At present, both the airborne ATR chassis structure and the reinforced computer with the upper cabinet chassis structure have proposed a closed chassis structure with module (such as blades, etc.) cooling and external air duct circulation, which can meet the requirements of the harsh military environment. However, this type of structure has a large performance restriction on the equipment and cannot meet the heat dissipation of multi-blade equipment. Specifically, the heat dissipation structure commonly used in traditional military closed computers is to design external air duct plates for heat dissipation up and down, left and right. This method only has a good heat dissipation effect on the modules attached to the air duct plates, while other modules that are not attached to the wall can only be cooled by cooling, and the heat dissipation effect is poor. For the existing multi-blade chassis, only the module frame is used for sealing. Although it can meet the heat dissipation needs of the equipment, it cannot meet the requirements of harsh environmental indicators such as high mold, salt spray, and humidity. In addition, there are the following disadvantages: 1) Devices such as filters are connected to the outside air, which requires these components to have good enough resistance to moisture, heat, mildew and salt spray, and the requirements for components are relatively high; 2) The closed design and sealing operation of the module rack are difficult. For example, when using a crimped VPX socket, the VPX socket mounting hole on the passive backplane penetrates the backplane. If it is not sealed, external moisture can easily enter the sealed module rack and cause damage to the components. Currently, it can only be sealed by dispensing glue, and the operation process is relatively cumbersome.

[0004] Therefore, in view of the relatively harsh operating environment of military computers, higher requirements are put forward for mold, salt spray, humidity and heat, etc. At the same time, in order to ensure the overall beauty of the chassis, a high-density blade reinforced chassis structure resistant to high humidity and heat environment is proposed, which can not only meet the heat dissipation of the equipment, but also meet the higher mold, salt spray, humidity and heat environment requirements.

The module frame bottom plate 11 and the bottom wall of the box body form a first chamber and are provided with a plurality of first air duct openings arranged side by side, the air inlet is communicated with the first chamber, the module frame cover plate 13 and the top wall of the box body form a second chamber and are provided with a plurality of second air duct openings arranged side by side, the air outlet is communicated with the second chamber, at least one cold conduction plate 12 is arranged side by side, the cold conduction plate 12 is provided with a third air duct opening vertically penetrating therethrough, the module frame bottom plate 11 and the module frame cover plate 13 are respectively connected to the bottom wall and the top wall of the cold conduction plate 12, and the third air duct opening of each cold conduction plate 12 is communicated with the first air duct opening and the second air duct opening in a one-to-one correspondence, the heat dissipation surface of the blade 2 is attached to the cold conduction plate 12, and the passive back plate 14 is electrically connected to the blade 2;

[0035] The heat dissipation component 9 includes a plurality of fans 91, which are connected to the box body and correspond to the air outlet.

[0036] Among them, the heat dissipation surface of the blade 2 is attached to the cold plate 12, specifically, the blade 2 can be attached to one side of the cold plate 12 or to both sides.

[0038] In one embodiment, the high-density blade reinforced chassis for high-humidity and high-heat environment also includes a windshield assembly 8 built into the chassis, the windshield assembly 8 includes a windshield cover 81 and a plurality of fan interfaces 82 connected to each other, the fan interface 82 is electrically connected to the fan 91 in a one-to-one correspondence, the windshield cover 81 is respectively connected to the chassis and the module frame cover 13 to form a third chamber, the fan 91 is built into the third chamber, and the module frame cover 13 is also provided with a fourth air duct opening, the fourth air duct opening is connected to the third chamber.

[0039] In one embodiment, the wind shield 81 also forms a closed fourth chamber with the box body, the passive backplane 14, the module frame bottom plate 11 and the module frame cover plate 13 respectively.

The wind shield 81, the box body, the passive backplane 14, the module frame bottom plate 11 and the module frame cover 13 form a closed fourth chamber, and the board is built in the fourth chamber, which helps to provide a good sealing environment for the board, and a sealing strip can be further provided on the contact surface between the wind shield 81 and the box body and the module frame cover 13 to improve the sealing performance.

[0040] In one embodiment, the box body includes a left side plate 3, a front panel 4, a lower cover plate 6, a right side plate 7, an upper cover plate 10 and a rear panel 16 which together form a square frame. The left side plate 3 and the right side plate 7 are arranged opposite to each other, the front panel 4 and the rear panel 16 are arranged opposite to each other, the lower cover plate 6 and the upper cover plate 10 are arranged opposite to each other, and the lower cover plate 6 serves as the bottom wall of the box body, and the upper cover plate 10 serves as the top wall of the box body. The contacting surfaces of the panels of the box body can be further provided with sealing strips to improve the sealing performance.

[0041] In one embodiment, the box body further includes a maintenance door 5, a window is provided on the front panel 4, and the maintenance door 5 is connected to the front panel 4 and covers the window. The maintenance door 5 can be detachably connected to the front panel 4, such as by screw connection or snap connection, so as to facilitate opening for maintenance inside the box body, and the maintenance door 5 can be further sealed to the front panel 4 to improve the sealing performance.

[0042] In one embodiment, the air inlet is opened on the left side panel 3, the front panel 4 and the right side panel 7 and is arranged close to the lower cover plate 6, and the fan 91 is installed on the rear panel 16. The fan 91 corresponds to the air outlet on the rear panel 16 and is used to quickly drain the air out of the chassis.

[0043] In one embodiment, the module frame 1 further includes a plurality of first sealing strips 15, and the bottom wall and the top wall of the cold conducting plate 12 are respectively sealed and connected to the module frame bottom plate 11 and the module frame cover plate 13 through the first sealing strips 15. The first sealing strips 15 can not only play an electromagnetic shielding role for the cavity where the board is located, but also form an independent closed cavity, thereby preventing external moisture from entering the closed cavity where the board is located.

[0044] In one embodiment, the bottom wall and the top wall of the cold conduction plate 12 are respectively provided with a first groove 121, and the first sealing strip 15 is installed in the first groove 121.

[0045] In one embodiment, the heat dissipation assembly 9 further includes a second sealing strip 92, and the fan 91 is sealed and connected to the box body through the second sealing strip 92. The second sealing strip 92 ensures the sealing performance of the air duct, thereby improving the heat dissipation performance, isolating the external environment and ensuring the service life of the device.

[0046] In one embodiment, a plurality of heat dissipation fins arranged side by side in the horizontal direction are provided in the third air duct opening of the cold conduction plate 12. The heat dissipation surface of the blade 2 with relatively large power consumption is attached to the cold conduction plate 12. After the power consumption of the chip on the blade 2 is transferred to the heat dissipation surface, the heat is quickly transferred to the heat dissipation fins in the cold conduction plate through the surface attached to the cold conduction plate 12. The heat dissipation fins help to increase the heat dissipation area and achieve rapid heat dissipation.

[0047] The whole machine air duct is as follows Figure 7 As shown, when the fan 91 is started, it drives the airflow so that air enters from the lower air inlets of the left side panel 3, the front panel 4 and the right side panel 7, flows in from the lower end of the module frame 1 (the first air duct opening of the module frame bottom plate 11), flows through the heat dissipation teeth in the third air duct opening of the cold conduction plate 12, takes away the heat, and then flows out from the upper end of the module frame 1 (the second air duct opening of the module frame cover 13), and the fan 91 installed on the rear panel 16 takes the heat out of the chassis. The specific flow direction is indicated by the arrow in the reference figure.
