Description

Technical Field

[0001] The utility model relates to an ATR case, in particular to an ATR closed case based on air cooling and heat dissipation. Background Art

[0002] In the field of electronic industrial products, the heat dissipation of ATR chassis and its electromagnetic shielding effect and IP protection level are often in conflict with each other. The heat dissipation of ATR chassis usually adopts through-type air cooling or natural heat dissipation of the chassis. If natural heat dissipation is adopted, there is no need to open air ducts and ventilation holes on the chassis, and the 3U modules installed inside the chassis are isolated from the outside world. In this way, the electromagnetic protection effect and IP protection level are better, but the heat dissipation effect of a fully enclosed chassis is limited, so the natural heat dissipation method is only used on low-power chassis. If it is a high-power chassis, it will generate a lot of heat in a short time when it is working. This heat cannot be quickly dissipated by natural heat dissipation alone, which is easy to cause 3U module failure. Therefore, high-power chassis generally adopt through-type air cooling. This heat dissipation method requires opening ventilation holes on the chassis and installing fans. The fans blow cold air from the outside into the chassis. After the cold air enters, it will flow between the 3U modules and finally take the heat out through the air outlet. This heat dissipation method is simple and efficient, but the electromagnetic shielding effect of the chassis will be reduced after the holes are opened, and the fan will also bring external dust into the chassis during the process of blowing cold air into the chassis. After long-term operation, a large amount of dust will accumulate on the surface of each 3U module due to the adsorption of static electricity, which will further affect the electromagnetic shielding effect and IP protection level, and reduce the reliability of the product.

DETAILED DESCRIPTION

[0030] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Reference Figure 1-Figure 4 The utility model is an ATR closed chassis based on air cooling, including a box body with a rectangular structure surrounded by an upper cover plate 1, a bottom plate 2, a front panel 3, a rear frame 4, a right outer sealing plate 5 and a left outer sealing plate 6, and there are gaps between the rear frame 4 and the right outer sealing plate 5 and the left outer sealing plate 6.

[0032] A right heat sink 7 and a left heat sink 8 are arranged in the box body, wherein the right heat sink 7 is arranged close to the right outer sealing plate 5, and the left heat sink 8 is arranged close to the left outer sealing plate 6, the upper and lower ends of the right heat sink 7 and the left heat sink 8 are respectively connected to the upper cover plate 1 and the bottom plate 2, and the rear end surfaces of the right heat sink 7 and the left heat sink 8 are respectively connected to the rear frame 4, the gap between the right outer sealing plate 5 and the right heat sink 7 constitutes a first heat dissipation channel 15, and the gap between the left outer sealing plate 6 and the left heat sink 8 constitutes a second heat dissipation channel 16.

[0033] In order to improve the heat dissipation effect, a fan 11 is arranged on the front panel 3, and an air guide 10 is arranged inside and relative to the fan 11. The air guide 10 includes a front frame 1001 and an air guide structure arranged in the front frame 1001. Ventilation holes are opened on the left and right side walls of the front frame 1001, and the two vents are respectively connected to the first heat dissipation channel 15 and the second heat dissipation channel 16. The rear side surface of the front frame 1001 is respectively connected to the front end surface of the right heat dissipation plate 7 and the left heat dissipation plate 8, and the upper and lower ends of the front frame 1001 are respectively connected to the upper cover plate 1 and the bottom plate 2. A plurality of slot plates 12 for fixing the 3U module 13 are arranged between the right heat dissipation plate 7 and the left heat dissipation plate 8, and the left and right sides of each slot plate 12 are respectively connected to the left heat dissipation plate 8 and the right heat dissipation plate 7, so that when the 3U module 13 generates heat, its heat can be directly transferred to the two heat dissipation plates by the slot plate 12, thereby improving the heat dissipation efficiency. A motherboard 9 is connected to the inner side of the base plate 2. The motherboard 9 is used for electrical connection between each 3U module 13. The motherboard 9 is located between the upper cover plate 1 and the base plate 2. The upper end of the slot board 12 is connected to the upper cover plate 1, and the lower end is connected to the motherboard 9. In this way, the connection stability of the slot board 12 is improved, and its heat can also be transferred to the motherboard 9 and the upper cover plate 1. In order to enhance the heat dissipation effect of the upper cover plate 1, a plurality of heat dissipation teeth 101 for increasing the heat dissipation area are arranged on the outer wall of the upper cover plate 1.

[0034] In order to improve the heat dissipation efficiency, the right heat sink 7 and the left heat sink 8 are made of aluminum alloy material. Compared with general metal materials, aluminum alloy material has good thermal conductivity, light weight and high structural strength, which will not affect the overall weight of the ATR chassis too much. The heat generated by the operation of the 3U module 13 is transferred to the two heat sinks through the slot plate 12, and the heat is taken away by the cold air in the two heat dissipation channels. In order to increase the heat dissipation area of ​​the two heat sinks, heat dissipation fins 14 are provided on the outer sides of the right heat sink 7 and the left heat sink 8.

[0035] The wind-guiding structure includes a wind-blocking piece and a plurality of lateral wind-guiding plates 1003 arranged on both sides of the wind-blocking piece. The wind-blocking piece includes a central cylinder 1002 arranged in the front frame 1001 and an upper wind-blocking plate 1004 and a lower wind-blocking plate 1005 connected to the central cylinder 1002. One end of the upper wind-blocking plate 1004 is connected to the central cylinder 1002, and the other end is connected to the upper side plate of the front frame 1001. One end of the lower wind-blocking plate 1005 is connected to the central cylinder 1002, and the other end is connected to a horizontal plate 1006 arranged in the front frame 1001 and located between the lower side plate and the upper side plate. The groove-shaped space surrounded by the horizontal plate 1006, the lower side plate, and the left and right side walls is to leave installation space for the control switch, external interface, indicator light, etc. located below the fan 11 on the front panel 3 to prevent interference with the wind-guiding structure. Furthermore, the upper and lower parts are separated by the horizontal plate 1006, which can also prevent the cold wind blown in by the fan 11 from affecting the connection of the control switch, the external interface and the indicator light.

[0036] In order to equally divide the cold air blown in by the fan 11 and guide it to the first heat dissipation channel 15 and the second heat dissipation channel 16 respectively, the center dividing planes of the central cylinder 1002, the upper air baffle plate 1004 and the lower air baffle plate 1005 in the vertical direction coincide with the center dividing plane of the front frame 1001 in the vertical direction, and the center dividing plane of the fan 11 in the vertical direction and the center dividing plane of the front frame 1001 in the vertical direction are located in the same plane, so that the cold air blown in by the fan 11 can be roughly equally divided, ensuring that the air volume entering the two heat dissipation channels is basically the same. In order to guide all the cold air into the heat dissipation channel, four lateral air guide blades 1003 are further provided. The four lateral air guide blades 1003 are symmetrically arranged about the center dividing plane of the front frame 1001 in the vertical direction, and two are arranged on each side. One end of each lateral air guide blade 1003 is connected to the central cylinder 1002, and the other end is connected to the side wall of the front frame 1001. In this way, the cold air is guided to the vents on the side walls of the front frame 1001 through the lateral air guide blades 1003. At this time, although the cold air is guided by the lateral air guide blades 1003 and its general flow direction is consistent, turbulence still exists. Therefore, a rectifier plate 1007 is arranged at the vent. Multiple rectifier plates 1007 are arranged in the horizontal direction and evenly distributed in the vertical direction to further rectify the cold air, and the rectifier plates 1007 are arranged corresponding to the heat dissipation fins 14. In this way, the cold air guided by the air guide structure will be re-rectified when passing through the rectifier plate 1007. Because the rectifier plate 1007 is set corresponding to the heat dissipation fins 14, the rectified cold air will enter between the heat dissipation fins 14 to prevent turbulence from affecting the overall heat dissipation effect of the chassis.

[0037] When in use, the fan 11 is started, and the fan 11 blows cold air from the outside air into the chassis. The cold air first passes through the air guide 10 when entering the chassis, and is basically evenly divided into two parts by the upper and lower air baffles and the central cylinder 1002. The cold air is then guided to the vents on the side wall of the front frame 1001 by the lateral air guide 1003, and after being rectified by the rectifier 1007 at the vents, it enters the first heat dissipation channel 15 and the second heat dissipation channel 16 respectively. At the same time, the heat generated by the 3U module 13 will be transferred to the left and right heat dissipation plates through the slot board 12 and the air, and the cold air entering the heat dissipation channel will take away the heat, ensuring the normal operation of the chassis, and the 3U module 13 will not be in direct contact with the cold air during the heat dissipation process, ensuring the electromagnetic shielding effect and IP protection level of the ATR chassis.

[0038] The embodiments described above are merely descriptions of the specific implementation methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
