Description

Technical Field

[0001] This invention belongs to the field of computer technology for harsh environments, and in particular relates to an ATR-type air-cooled LRM ruggedized chassis. Background Technology

[0002] With the rapid development of science and technology, military electronic equipment is becoming increasingly integrated, environmental adaptability requirements are becoming more stringent, and the requirements for the structure and shape of the equipment are becoming more compact. Therefore, a more integrated structural form is needed to meet the usage requirements.

[0003] LRM (Large Scale-Resistant) architecture technology arose under the technical requirements of ultra-high-speed, ultra-large-scale integrated circuits. LRM modules are relatively independent in structure and function, with standard dimensions and interfaces, and a hermetically sealed protective casing. In addition, LRM modules offer the following advantages: First, excellent maintainability. The BIT (Bit-In-Time) function of LRM modules allows the system to isolate faults to each module. If a system failure occurs, simply replacing the faulty module in the field will restore normal operation. Second, independent resistance to harsh environments, including resistance to salt spray, mold, humidity, and electromagnetic shielding. Third, resource sharing. Utilizing fiber optic bus technology, signal processing, power supply, and other resources can be shared, reducing system complexity and equipment size and weight.

[0004] An LRM chassis is a chassis that houses LRM modules. Regarding heat dissipation, if the LRM module has low heat dissipation, it typically cools naturally through conduction and radiation; if the LRM module has high power consumption, it cools through conduction combined with air cooling or conduction combined with liquid cooling. In terms of chassis structure, depending on space constraints, single-layer or multi-layer module mounting can be used, with the LRM module mounted independently on the rack. However, regardless of the cooling method or mounting structure, conventional LRM chassis are open-type, meaning the LRM module is exposed. Furthermore, assuming the angle between the line containing the LRM module's insertion / removal direction and the chassis's external interface (or connector) mounting surface is θ, then in a conventional LRM chassis, 0° < θ ≤ 90°.

[0005] Since the ATR chassis is a fully sealed chassis, and the module insertion / removal direction within the ATR chassis is parallel to the mounting surface of the chassis's external interfaces (or connectors), i.e., θ = 0°, the existing LRM chassis structure described above is clearly unsuitable for the ATR chassis operating environment. Therefore, it is necessary to develop an ATR-type air-cooled LRM rugged chassis. The heat dissipation and insertion / removal of the LRM modules within the enclosed space, as well as the sealing of other components besides the LRM modules and the electrical installation of the chassis, are the primary issues that need to be considered when designing an ATR-type air-cooled LRM rugged chassis. Summary of the Invention

[0006] The purpose of this invention is to solve the problems mentioned in the background art and provide an ATR-type air-cooled LRM ruggedized chassis that is suitable for the use environment of ATR chassis, while having the advantage of field-replaceable LRM modules. It adopts air cooling to improve the heat dissipation efficiency of the sealed chassis, and has a compact structure and small size.

[0007] To achieve the objective of this invention, an ATR-type air-cooled LRM ruggedized chassis is disclosed, comprising a frame, an upper cover plate on the top of the frame, a lower cover plate on the bottom of the frame, and a bottom plate mounting plate on the upper surface of the lower cover plate. The frame is a cubic frame structure, with side panels, a front slot plate, a rear slot plate, and a panel frame on the sides. The side panels and panel frames are arranged opposite each other, as are the front and rear slot plates. A partition is provided between the side panels and the panel frames. A socket plate is provided on the outer side of the panel frame. The areas between the upper cover plate, socket plate, bottom plate mounting plate, and frame partition, and between the lower cover plate and bottom plate mounting plate, are sealed areas. The areas between the upper cover plate, side panels, front slot plate, rear slot plate, partition, and bottom plate mounting plate are unsealed areas. An LRM module is provided on the bottom plate mounting plate. Heat dissipation holes are provided on the front and rear slot plates corresponding to the unsealed areas, and the LRM module dissipates heat through air convection between the front and rear slot plates.

[0008] Furthermore, a fan is installed on the outside of the heat dissipation holes of the front or rear slot plate to draw hot air out of the chassis; a fan cover is installed on the outside of the fan to form an air cavity and protect the fan; when the chassis is working, the heat of the LRM module is conducted to the heat dissipation fins of the LRM module itself. The heat dissipation fins face the air inlet, and the air inlet and outlet form a smooth airflow channel. The heat is carried away in time by the exhaust action of the fan.

[0009] Furthermore, on the side of the frame where the fan is located, the area outside the fan is enclosed by a duct cover.

[0010] Furthermore, conductive sealing material is installed between the overlapping surfaces of the upper cover plate, socket plate, bottom mounting plate and frame, and between the overlapping surfaces of the lower cover plate and bottom mounting plate to achieve sealing of the sealing area.

[0011] Furthermore, the chassis backplate is mounted on top of the base plate by screws passing through the mounting bracket, and the LRM module is mounted on the chassis backplate. The mounting bracket is used to increase the rigidity of the chassis backplate.

[0012] Furthermore, a connector is provided on the socket board, and the connection cable between the chassis back panel and the connector is located within the sealed area.

[0013] Furthermore, the LRM module is equipped with insertion and removal assist devices on both sides above it. The insertion and removal assist devices are U-shaped structural components with countersunk holes in the middle. The insertion and removal assist devices are connected to the frame by countersunk screws passing through the countersunk holes. One side of the U-shaped opening of the insertion and removal assist device is a pushing surface and the other side is a pulling surface. When installing the LRM module, the puller on the LRM module contacts the pushing surface in the insertion and removal assist device, and the LRM module is assembled into place by using the lever principle. When removing the LRM module, the puller on the LRM module contacts the pulling surface in the insertion and removal assist device, and the LRM module is pulled out of the chassis by using the lever principle.

[0014] Furthermore, the outer side of the socket panel is equipped with a bracket and a handle. The bracket is used to connect and fix the chassis to other equipment, and the handle is used to assist in moving the chassis.

[0015] Furthermore, the frame is constructed by brazing wall panels, front groove panels, rear groove panels, partitions, and panel frames together.

[0016] Furthermore, the upper cover plate is installed with non-loosening screws, while the lower cover plate is a movable structural component.

[0017] Compared with the prior art, the significant advancements of this invention are: 1) The chassis structure of this invention is designed according to the shape of an ATR chassis, making it suitable for the use environment of ATR chassis and breaking the limitations of conventional LRM chassis use environments; 2) The chassis of this invention installs an LRM module, integrating the advantages of the LRM module and enhancing the functional performance of the computer; 3) The chassis of this invention is divided into sealed and unsealed areas, which solves the problems of heat dissipation and plugging / unplugging of the LRM module in the enclosed space, as well as the sealing of other components besides the LRM module and the electrical installation problems of the chassis.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1 , Figure 6 , Figure 7 , Figure 9 As shown, an ATR-type air-cooled LRM ruggedized chassis includes a frame 1, an upper cover plate 2 on top of the frame 1, a lower cover plate 5 below the frame 1, and a bottom mounting plate 4 on the upper surface of the lower cover plate 5. The frame 1 is a cubic frame structure. The sides of the frame 1 are respectively a wall panel 1-1, a front slot plate 1-2, a rear slot plate 1-3, and a panel frame 1-5. The wall panel 1-1 and the panel frame 1-5 are opposite each other, and the front slot plate 1-2 and the rear slot plate 1-3 are opposite each other. A partition plate 1-4 is provided between the wall panel 1-1 and the panel frame 1-5. A socket plate 3 is provided on the outside of the panel frame 1-5. The areas between the upper cover plate 2, the socket plate 3, the bottom mounting plate 4 and the frame partition plate 1-4, and between the lower cover plate 5 and the bottom mounting plate 4 are sealed areas. Figure 9The area between the top cover plate 2, wall panel 1-1, front groove plate 1-2, rear groove plate 1-3, partition plate 1-4 and bottom mounting plate 4 is a non-sealed area. Figure 9 (Central B area); The base plate mounting plate 4 is equipped with an LRM module 11. The front slot plate 1-2 and the rear slot plate 1-3 are provided with heat dissipation holes in the areas corresponding to the non-sealed areas. The LRM module 11 dissipates heat through air convection between the front slot plate 1-2 and the rear slot plate 1-3.

[0033] like Figure 3 , Figure 4 , Figure 6 As shown, a fan 9 is provided on the outside of the heat dissipation holes of the rear slot plate 1-3 to draw hot air out of the chassis; a fan cover 8 is provided on the outside of the fan 9 to form an air cavity and protect the fan 9.

[0034] like Figure 7 , Figure 8 As shown, the area outside the fan 9 is enclosed by the air duct cover plate 1-6 on the outside of the rear duct plate 1-3.

[0035] like Figure 5 , Figure 9 As shown, the chassis is divided into two zones: Zone A and Zone B. Zone A is a sealed area, specifically the area between the upper cover plate 2, socket plate 3, bottom mounting plate 4 and frame partitions 1-4, and the area between the lower cover plate 5 and bottom mounting plate 4. The chassis back panel 12 and the connecting cables between the chassis back panel 12 and connector 15 are located in Zone A. Conductive sealing material 14 (such as graphite nickel-plated conductive rubber strips) is installed between the overlapping surfaces of the upper cover plate 2, socket plate 3, bottom mounting plate 4 and frame 1, and between the overlapping surfaces of the lower cover plate and bottom mounting plate 4, to achieve sealing of Zone A. Zone B is a non-sealed area (within the dashed box), specifically the area between the upper cover plate 2, wall panel 1-1, front groove plate 1-2, rear groove plate 1-3, partition 1-4 and bottom mounting plate 4. The fan 9 and LRM module 11 are located in Zone B. An air inlet is provided in the front slot plate 1-2, and an air outlet is provided in the rear slot plate 1-3. When the chassis is working, the heat of the LRM module 11 is conducted to the heat dissipation fins. The heat dissipation fins are directly facing the air inlet, and the air inlet and air outlet form a relatively smooth airflow channel. The heat is carried away in time by the exhaust action of the fan 9.

[0036] like Figure 5 As shown, the chassis backplate 12 is mounted on the base plate 4 by screws passing through the mounting bracket 13. The LRM module 11 is mounted on the chassis backplate 12. The mounting bracket 13 is used to increase the rigidity of the chassis backplate 12.

[0037] like Figure 2 As shown, a connector 15 is provided on the socket plate 3, and the connection cable between the chassis back plate 12 and the connector 15 is located in the sealed area.

[0038] like Figure 4 , Figure 10 As shown, insertion and removal aids 10 are provided on both sides of the upper part of the LRM module 11. The insertion and removal aids 10 are U-shaped structural components with countersunk holes in the middle. The insertion and removal aids 10 are connected to the frame 1 by countersunk screws passing through the countersunk holes. One side of the U-shaped opening of the insertion and removal aids 10 is a pushing surface and the other side is a pulling surface. When installing the LRM module 11, the puller on the LRM module 11 contacts the pushing surface in the insertion and removal aids 10, and the LRM module 11 is assembled into place by using the lever principle. When removing the LRM module 11, the puller on the LRM module 11 contacts the pulling surface in the insertion and removal aids 10, and the LRM module 11 is pulled out of the chassis by using the lever principle.

[0039] like Figure 2 As shown, the outer side of the socket plate 3 is provided with a bracket 6 and a handle 7. The bracket 6 is used to connect and fix the chassis to other equipment, and the handle 7 is used to assist in the handling of the chassis.

[0040] Specifically, in this embodiment, the frame 1 is formed by brazing the wall panel 1-1, the front groove plate 1-2, the rear groove plate 1-3, the partition plate 1-4, and the panel frame 1-5.

[0041] Specifically, in this embodiment, the upper cover plate 2 is installed with non-loosening screws, while the lower cover plate 5 is a movable structural component. The upper cover plate 2 being a movable structural component, and the use of non-loosening screws for its installation with the frame 1, facilitates the assembly and debugging of the LRM module 11 and solves the problem of lost screws when the upper cover plate 2 is frequently disassembled and reassembled. The lower cover plate 5 being a movable structural component facilitates electrical installation of the chassis.

[0042] Specifically, the implementation process of this device is as follows: During electrical construction, the lower cover plate 5 can be opened to perform welding operations between the chassis backplate 12 and the connector 15, etc. When plugging and unplugging modules, the upper cover plate 2 can be opened to perform assembly operations on the LRM module 11.

[0043] The chassis of this invention is divided into sealed and unsealed areas, which solves the problems of heat dissipation and plugging / unplugging of LRM modules in enclosed spaces, as well as the sealing of other components besides LRM modules and the electrical installation of the chassis.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
