[0003] During the operation of specific embodiments, the inventors discovered the following defects:
[0004] Existing CAN converters often lack effective heat dissipation structures or have poorly designed ones, resulting in heat not dissipating in a timely manner and causing the CAN converter to operate in high-temperature environments for extended periods. High temperatures affect the performance and lifespan of the internal electronic components of the CAN converter, and in severe cases, can even lead to equipment failure, reducing the reliability and stability of the CAN converter and failing to meet the requirements of long-term stable operation in practical applications. Therefore, designing an efficient heat dissipation structure is of great significance for improving the performance and reliability of CAN converters.
[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0030] See attached document Figure 1-5A CAN converter with a heat dissipation structure includes a CAN converter body 1, a heat dissipation shell 2 on the outside of the CAN converter body 1, forming a heat dissipation cavity between the heat dissipation shell 2 and the CAN converter body 1, and support legs 3 installed at the four corners of the bottom side of the heat dissipation shell 2; the heat dissipation shell 2 includes an inner heat-conducting layer 4 and an outer heat dissipation fin layer 5. The heat-conducting layer 4 is supported by a metal material with a high thermal conductivity for quickly conducting the heat generated by the CAN converter body 1. The heat dissipation fin layer 5 consists of multiple parallel heat dissipation fins extending in a direction perpendicular to the surface of the CAN converter body 1 to increase the heat dissipation area; the front side of the heat dissipation shell 2 has a detachable mounting bracket. The sealing cover 6 has cooling fans 7 installed at both ends of its inner wall. The cooling fans 7 are located inside the heat dissipation cavity. The sealing cover 6 has an air inlet 600 corresponding to the position of the cooling fans 7, and the rear wall of the heat dissipation shell 2 has an air outlet 200 corresponding to the position of the cooling fans 7. The air forms forced convection inside the heat dissipation cavity, which accelerates the heat dissipation speed. The top and bottom of the heat dissipation shell 2 have multiple strip-shaped heat dissipation vents 201, which can realize the heat dissipation of the top and bottom of the CNA converter body 1. The top and bottom of the CNA converter body 1 are provided with thermal conductive silicone pads 8, which are tightly attached to the CNA converter body 1 and the thermal conductive layer 4, respectively, so that heat can be smoothly conducted.
[0031] In this embodiment, dustproof nets 9 can be detachably installed at both the air inlet 600 and the air outlet 200.
[0032] It should be noted that during routine maintenance, the dust filters 9 at the air inlet 600 and air outlet 200 should be cleaned regularly. A clogged dust filter 9 will affect the heat dissipation effect. If the cooling fan 7 is found to be faulty or its heat dissipation effect is reduced, it should be repaired and replaced in time to ensure the normal operation of the entire heat dissipation system.
[0033] In this embodiment, magnetic slide rails 202 are provided on both the top and bottom sides of the heat dissipation shell 2. A magnetic slider 10 is slidably installed inside the magnetic slide rail 202. A baffle 11 is fixedly installed at the end of the magnetic slider 10. The upper and lower baffles 11 slide to cover the top and bottom of the heat dissipation shell 2. The rear ends of the two baffles 11 are fixedly connected by two connecting rods 12.
[0034] It should be noted that the magnetic slider 10 can slide along the inside of the magnetic slide rail 202 to move the baffle 11 backward, thereby exposing the covered strip heat dissipation vent 201, which can realize heat dissipation at the top and bottom of the CNA converter body 1 and improve the heat dissipation effect.
[0035] In this embodiment, a handle 13 is fixedly connected to the top surface of the top baffle 11 of the heat dissipation housing 2.
[0036] It should be noted that this allows for easy back-and-forth pushing of the baffle 11.
[0037] In this embodiment, the sealing cover 6 is U-shaped laterally. Threaded holes 601 are provided on both the upper and lower sides of the sealing cover 6. A screw 14 is threaded through the threaded hole 601. An adjusting block 15 is installed at the outer end of the screw 14. A clearance groove 602 is provided inside the threaded hole 601. A limiting block 16 is installed at the inner end of the screw 14. The limiting block 16 slides and fits inside the clearance groove 602. A limiting groove 203 is provided on the side wall of the heat dissipation shell 2 for the limiting block 16 to be inserted into the limiting groove.
[0038] It should be noted that when installing the sealing cover 6, the inner wall of the sealing cover 6 is attached to the outer wall of the heat sink housing 2. By rotating the adjusting block 15, the screw 14 is moved horizontally, causing the limiting block 16 to slide inside the relief groove 602, so that the limiting block 16 moves into the inside of the limiting groove 203, thereby fixing the sealing cover 6 in place. When removing the sealing cover 6, the adjusting block 15 is rotated in the opposite direction, causing the screw 14 to move horizontally outward, causing the limiting block 16 to move away from the inside of the limiting groove 203 and into the inside of the relief groove 602, thus completing the removal of the sealing cover 6. This facilitates the inspection and maintenance of the CNA converter body 1 and the cooling fan 7, ensuring normal operation.
[0039] The working principle of this utility model is as follows: In use, firstly, the CNA converter body 1 is installed inside the heat dissipation housing 2. Thermally conductive silicone pads 8 are attached to the top and bottom of the CNA converter body 1, ensuring close contact between the thermally conductive silicone pads 8 and the CNA converter body 1 and the thermally conductive layer 4, allowing for smooth heat conduction. Then, the cooling fan 7 is installed on the inner wall of the sealing cover 6. Next, the sealing cover 6 is fixed to the front side of the heat dissipation housing 2, with the inner wall of the sealing cover 6 adhering to the outer wall of the heat dissipation housing 2. By rotating the adjusting block 15, the screw 14 is moved horizontally. The limiting block 16 slides inside the relief groove 602, causing the limiting block 16 to move into the inside of the limiting groove 203, thereby fixing the sealing cover 6 and connecting the power cord of the cooling fan 7 to the power module of the CNA converter body 1 to power the cooling fan 7. During use, when the CNA converter body 1 generates heat, the heat is first transferred to the heat-conducting layer 4 through the thermally conductive silicone pad 8. The heat-conducting layer 4 quickly conducts the heat to the heat dissipation fin layer 5. At the same time, the cooling fan 7 starts, and air enters the heat dissipation cavity from the air inlet 600. Under the action of the cooling fan 7, air flows through the CNA converter body 1 and the heat dissipation shell 2, carrying away heat and then being discharged from the air outlet 200. The continuous flow of air forms forced convection, which accelerates the heat dissipation speed, allowing the CNA converter body 1 to operate at a lower temperature and ensuring the stability of the equipment operation. By pushing the upper and lower baffles 11 with the handle 13, the magnetic slider 10 slides backward along the inside of the magnetic slide rail 202, exposing the strip-shaped heat dissipation vents 201 at the top and bottom of the heat dissipation shell 2, which can further improve the heat dissipation effect of the CNA converter body 1. When top and bottom heat dissipation is not required, the baffles 11 can be used to cover the top and bottom of the heat dissipation shell 2, which is waterproof. In daily maintenance, the dustproof nets 9 at the air inlet 600 and the air outlet 200 should be cleaned regularly. If the dustproof nets 9 are blocked, the heat dissipation effect will be affected. If the cooling fan 7 is found to be faulty or the heat dissipation effect is reduced, it should be repaired and replaced in time to ensure the normal operation of the entire heat dissipation system.
[0040] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
