Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, specifically to an auxiliary air-cooled VPX reinforced heat-conducting chassis. Background Technology

[0002] The VPX bus is a new generation of high-speed serial bus standard proposed based on the VME bus. Its basic specifications, mechanical structure and bus signals are defined in the ANSI / VITA46 series of technical specifications. This bus uses high-speed serial bus technology to replace the parallel bus technology of the VME bus, introduces the latest serial bus technology, and strongly supports higher backplane bandwidth.

[0003] With the widespread application of VPX technology, the power consumption of VPX plugins has increased significantly, and the heat generated per unit time has risen sharply.

[0004] Current VPX chassis structures are generally similar to those described in patent application CN202423140791.6, comprising a chassis body with open front and rear ends, a front panel fixedly mounted at the front end, and a rear panel fixedly mounted at the rear end. Inside the chassis body, a motherboard is arranged along the left-right direction, with a first connection area and a second connection area. The first connection area is used to securely connect front expansion cards, and the second connection area is used to securely connect rear expansion cards. Different types of VPX connectors are provided in each connection area, used to connect front or rear expansion cards of different depths. An air inlet is located on the left side of the chassis body, and an air outlet is located on the right side. The VPX chassis in this application allows for support of expansion cards of different depths, avoiding the need to replace the chassis when using expansion cards of different depths, reducing costs and maintenance difficulty, and improving heat dissipation. This structure improves the heat dissipation of VPX expansion cards to a certain extent. However, it cannot solve the problem of low structural strength in complex environments and inability to adapt to working in environments with vibration or electromagnetic interference.

[0005] Current signal processors generally have a structure similar to that described in patent application number "CN202420841846.7". This structure includes a housing with a mounting cavity inside. One end of the mounting cavity has an opening communicating with it, and an aviation connector cover is installed at the opening. A base PCB board for inserting multiple VPX cards is located within the mounting cavity. An aviation connector PCB board is positioned between the aviation connector cover and the base PCB board, and the aviation connector PCB board and the base PCB board are connected via a rigid connection component. This invention, by adding an aviation connector PCB board between the base PCB board and the aviation connector cover, achieves electrical connection through insertion between the cover and the PCB board. Furthermore, the rigid connection component connects the base PCB board and the aviation connector PCB board, achieving signal connection. This design makes the rigid connection less prone to damage or detachment when the processor encounters impacts, improving processor stability and making it more durable and with a longer service life. This structure improves the environmental adaptability of VPX boards to some extent, but it cannot solve the heat dissipation problem of VPX high-speed boards.

[0006] In summary, ordinary small air-cooled VPX modules have drawbacks such as poor heat dissipation performance, poor reliability, and poor environmental adaptability when facing complex environmental conditions.

[0007] Therefore, this utility model proposes an auxiliary air-cooled VPX reinforced cooling chassis to solve the above-mentioned problems. Utility Model Content

[0008] The purpose of this invention is to provide an auxiliary air-cooled VPX reinforced heat dissipation chassis to solve the problems of poor heat dissipation performance, poor reliability and poor environmental adaptability in the prior art.

[0009] The technical solution adopted by this utility model to solve its technical problem is:

[0010] A ruggedized VPX chassis with auxiliary air cooling includes a chassis body. The chassis body includes a chassis shell and a front panel, a rear panel, and a bottom heat sink connected to the chassis shell. Multiple parallel VPX insertion slots are provided inside the chassis shell. An air inlet is provided on one side of the bottom heat sink near the rear panel, and an air outlet is provided on the other side. Multiple axial fans are connected to the bottom of the chassis shell and are positioned between the air inlet and the air outlet. Multiple axial fans are also connected to the rear panel. Multiple air deflectors are provided between the rear panel and the VPX insertion slots, and the air deflectors are inclined.

[0011] Furthermore, the axial fan is connected to the chassis housing via a shock-absorbing bracket, which includes an elastic rubber pad and a metal bracket, with the elastic rubber pad disposed between the metal bracket and the chassis housing.

[0012] Furthermore, the front panel, rear panel, and bottom heat sink are all detachably connected to the chassis housing by bolts, and the front panel is equipped with a working status indicator light and a power connector.

[0013] Furthermore, a dust filter is connected to the air inlet, and the dust filter is detachably connected to the bottom heat sink.

[0014] Furthermore, the bottom heat sink and the chassis body are connected by mounting ears, which are L-shaped and have mounting holes. A handle is also connected to the mounting ear.

[0015] Furthermore, the bottom of the bottom heat sink is provided with an air outlet channel, which is connected to the air outlet.

[0016] Furthermore, multiple heat sinks are evenly arranged on the chassis shell; multiple heat sinks are also evenly arranged on the bottom heat sink box.

[0017] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The bottom heat sink of this utility model has an air inlet on one side near the rear panel and an air outlet on the other side, forming an airflow channel and providing basic conditions for heat dissipation inside the chassis. Multiple heat sinks are evenly arranged on the chassis shell and the bottom heat sink, increasing the heat dissipation area and more effectively dissipating heat from inside the chassis to the external environment. The axial fan accelerates the airflow speed, quickly removing heat generated by VPX modules and other devices inside the chassis, improving heat dissipation efficiency and effectively solving the problem of poor heat dissipation performance of ordinary small air-cooled VPX modules. The inclined air guide plate guides the air to be evenly distributed, avoiding heat dissipation dead zones and further improving the heat dissipation effect on the modules.

[0019] 2. The air inlet of this utility model is connected to a dust filter, which is detachably connected to the bottom heat sink, making it convenient to clean or replace the dust filter and prevent dust from entering the chassis and affecting the normal operation of the equipment. The bottom heat sink and the chassis body are connected by mounting ears, which are L-shaped and have mounting holes to facilitate fixing the chassis to other equipment or racks. The mounting ears are also connected to handles to facilitate the handling and movement of the chassis. Attached Figure Description

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0033] like Figure 1-10 As shown, an auxiliary air-cooled VPX reinforced heat dissipation chassis includes a chassis body, which includes a chassis shell 2 and a front panel 3, a rear panel 4 and a bottom heat dissipation box 5 connected to the chassis shell 2. The chassis shell 2 is provided with a plurality of parallel VPX plug-in slots 6.

[0034] Furthermore, the bottom heat sink 5 has an air inlet 7 on one side near the rear panel 4 and an air outlet 8 on the other side; a dust filter 9 is connected to the air inlet 7, and the dust filter 9 is detachably connected to the bottom heat sink 5. The bottom heat sink 5 and the chassis body are connected by mounting ears 10, which are L-shaped and have mounting holes 11. A handle 12 is also connected to the mounting ears 10. An air outlet duct 13 is provided at the bottom of the bottom heat sink 5, and the air outlet duct 13 communicates with the air outlet 8. Multiple heat sinks 14 are evenly distributed on the chassis shell 2; multiple heat sinks 14 are also evenly distributed on the bottom heat sink 5.

[0035] Furthermore, multiple axial fans 15 are connected to the bottom of the chassis housing 2, and the axial fans 15 are positioned between the air inlet 7 and the air outlet 8; multiple axial fans 15 are also connected to the rear panel 4, and the axial fans 15 are connected to the chassis housing 2 via shock-absorbing brackets, which include elastic rubber pads 17 and metal brackets 18, with the elastic rubber pads 17 positioned between the metal brackets 18 and the chassis housing 2. Multiple air deflectors 19 are provided between the rear panel 4 and the VPX plug-in slot 6, and the air deflectors 19 are inclined.

[0036] Furthermore, the front panel 3, rear panel 4, and bottom heat sink 5 are all detachably connected to the chassis housing 2 by bolts. The front panel 3 is equipped with a working status indicator light 21 and a power connector 22.

[0037] The working process of this utility model is as follows:

[0038] When the chassis starts working, multiple axial fans 15 connected to the bottom of the chassis shell 2 start working, generating powerful airflow. Outside air enters through the air intake 7 on the side of the bottom heat sink 5 near the rear panel 4. The dust filter 9 connected to the air intake 7 filters the air, blocking dust, particles and other impurities in the air, preventing them from entering the chassis and affecting the normal operation of the VPX plug-in, thereby improving the chassis's dust resistance in complex environments. The dust filter 9 is detachably connected to the bottom heat sink 5, making it convenient to clean or replace the filter later, further enhancing the chassis's environmental adaptability.

[0039] Then, outside air enters the chassis housing 2. The chassis housing 2 is provided with multiple parallel VPX plug-in slots 6. The VPX plug-in is installed in the slots and generates heat when it is working. Multiple heat sinks 14 are evenly arranged on the chassis housing 2 and multiple heat sinks 14 are evenly arranged on the bottom heat sink 5, which can increase the heat dissipation area and accelerate the heat dissipation.

[0040] Multiple inclined air guides 19 are arranged between the rear panel 4 and the VPX plug-in slot 6. These guides 19 direct airflow, allowing it to flow more evenly and efficiently over the VPX plug-in and heatsink 14, carrying away heat generated during VPX plug-in operation and improving heat dissipation. Simultaneously, multiple axial fans 15 are connected to the rear panel 4. These fans are connected to the chassis housing 2 via vibration damping brackets, which include elastic rubber pads 17 and metal brackets 18. The elastic rubber pads 17 are positioned between the metal brackets 18 and the chassis housing 2, reducing vibration and noise generated by the axial fans 15 during operation, thus improving chassis reliability and environmental adaptability. When the axial fans 15 on the rear panel 4 operate, they push the heated air inside the chassis housing 2, creating an airflow circulation. The air absorbs heat within the chassis housing 2, becoming hot air, which is then exhausted outside the chassis through the exhaust vent 8.

[0041] Throughout the entire operation, the forced airflow is created by the axial fan 15 on the bottom heat sink 5 and the rear panel 4. Combined with the airflow guidance of the baffle 19 and the heat dissipation of the heat sink 14, the VPX plug-in can quickly dissipate heat under complex environmental conditions.

[0042] The front panel 3, rear panel 4, and bottom heat sink 5 are all detachably connected to the chassis housing 2 by bolts, which facilitates the assembly, disassembly, and maintenance of the chassis. The working status indicator light 21 installed on the front panel 3 can display the working status of the chassis in real time, and the power connection port 22 is used to connect to an external power source to provide power to the equipment inside the chassis.
