One end of the card plate 6 is engaged with the card slot 103 to fix the mounting plate 101 in the housing 2, and it is easy to assemble and disassemble, which is convenient for maintenance and repair of the communication concentrator body 1, and improves the use effect; a plurality of groups of heat sinks 102 are fixedly arranged on the communication concentrator body 1, and the heat sink 102 is arranged in two to twenty groups, preferably ten groups, and a first window 201 and a second window 202 are opened on the housing 2, and a heat dissipation fan 3 is fixedly arranged in the housing 2. When in use, by fixing the heat sink 102 on the communication concentrator body 1, the heat in the communication concentrator body 1 can be dissipated to the outside, and then through the heat dissipation fan 3, the air flow in the housing 2 can be accelerated, further improving the heat dissipation effect and reducing the impact on the performance and life of the equipment.

[0025] When in use, a U-shaped heat sink 102 is fixedly provided on the communication concentrator body 1 to help diffuse heat, and a heat dissipation fan 3 is fixedly provided in the outer shell 2 to accelerate the air flow in the outer shell 2, further improve the heat dissipation effect, and reduce the impact on the performance and life of the equipment; by removing and installing the dustproof net 4 at the first window 201 and the second window 202, it is convenient to clean the dustproof net 4, reduce the dust accumulated on the dustproof net 4, and improve the ventilation effect of the dustproof net 4.

[0026] Reference Figure 1 and Figure 4A limiting groove 205 is provided in the housing 2, the card plate 6 is slidably arranged in the limiting groove 205, a second spring 601 is provided in the limiting groove 205, the two ends of the second spring 601 are respectively against the card plate 6 and the limiting groove 205, and a through groove 104 connected to the card groove 103 is provided on the mounting plate 101, and an adjustment groove 206 connected to the limiting groove 205 is provided on the outer wall of the housing 2, so as to facilitate the sliding of the card plate 6. When in use, the mounting plate 101 needs to be removed from the housing 2. When removing from the shell 2, first push the card plate 6 to make it slide into the through groove 104. At this time, the card plate 6 is disengaged from the engagement connection with the card groove 103, and the mounting plate 101 can be removed from the shell 2; conversely, when installing, when the card plate 6 is also in the through groove 104, after the mounting plate 101 is installed in place, release the push on the card plate 6. Under the elastic force of the second spring 601, the card plate 6 slides into the card groove 103 and engages with the card groove 103, thereby fixing the mounting plate 101 in the shell 2.

[0027] Reference Figure 2 A first chamber and a second chamber are provided in the shell 2, and the first chamber and the second chamber are connected to each other at the inner top of the shell 2. A partition plate 7 is fixedly arranged between the first chamber and the second chamber, and the partition plate 7 is fixedly arranged at the inner bottom of the shell 2. The top of the partition plate 7 is against the bottom of the communication concentrator body 1. Here, a rubber pad 701 is fixedly arranged on the top of the partition plate 7, and the top of the rubber pad 701 is against the bottom of the communication concentrator body 1. The heat dissipation fan 3 is fixedly arranged in the first chamber, the first window 201 is connected to the first chamber, and the second window 202 is connected to the second chamber. When in use, by starting the heat dissipation fan 3, gas can be extracted from the outside through the first window 201, and then the gas flows through the heat sink 102, and finally flows out through the second window 202, thereby accelerating the air circulation in the shell 2 and improving the heat dissipation effect.

[0028] Reference Figure 2 , multiple groups of heat sinks 102 are all U-shaped structures, and their sizes increase outward in a divergent manner, with the two ends of the U-shape respectively located in the first chamber and the second chamber, that is, a heat dissipation channel approximately in a U-shape is naturally formed between two adjacent groups of heat sinks 102, and the two ends of the heat dissipation channel are respectively connected to the first chamber and the second chamber. When in use, by designing the heat sink 102 into a U-shaped structure, the gas enters from one end of the U-shape and then flows out from the other end, which can increase the contact area between the heat sink 102 and the air, and further improve the heat dissipation effect.

[0029] Reference Figure 2 and Figure 3A LORA communication concentrator also includes a dustproof net 4 arranged in a first window 201 and a second window 202, and a mounting frame 401 is slidably arranged in the first window 201 and the second window 202 respectively, and the dustproof net 4 is fixedly arranged in the mounting frame 401, and a limiting component for limiting the sliding of the mounting frame 401 is arranged on the shell 2. When in use, the mounting frame 401 can be fixed in the first window 201 and the second window 202 respectively by the limiting component to prevent the mounting frame 401 and the dustproof net 4 from falling during use, affecting normal use, and a sealing gasket is arranged in the first window 201 and the second window 202, and the top of the mounting frame 401 is against the bottom of the sealing gasket, so as to improve the sealing effect and reduce the dust from entering the shell 2.

[0030] Reference Figure 3 The limit assembly can use screws to fix the mounting frame 401 on the housing 2. Here, we design the limit assembly as a card block 5. There are four groups of card blocks 5, two groups are set at both ends of the first window 201, and two groups are also set at both ends of the second window 202. Among them, a guide groove 204 is opened in the housing 2, and the card block 5 is slidably set in the guide groove 204. A groove 402 is opened on the outer wall of the mounting frame 401, and one end of the card block 5 is engaged with the groove 402. A push plate 501 is slidably set on the housing 2, and one end of the push plate 501 extending to the guide groove 204 is fixed to the card block 5. The guide groove 204 is connected, and a first spring 502 is arranged in the guide groove 204, and the two ends of the first spring 502 are respectively pressed against the block 5 and the guide groove 204. When in use, the push plate 501 is pushed to make the block 5 slide into the guide groove 204, and then the installation frame 401 is installed in the first window 201 and the second window 202 respectively. After the installation is in place, the push on the push plate 501 is released. Under the elastic force of the first spring 502, the block 5 slides into the groove 402 to fix the installation frame 401. The operation is convenient and the fixation is reliable, which makes it easy to remove the dustproof net 4 for cleaning and improves the use effect.
