Description

Technical Field

[0001] The invention relates to a thick copper power circuit board, in particular to a thick copper power circuit board with a heat dissipation structure. Background Art

[0002] At present, circuit boards are the basic electronic components required by almost all electronic products. With the development of science and technology, the integration of electronic products is getting higher and higher, and the size is getting smaller and smaller, which makes the components on the circuit boards generate more and more heat, and the requirements for heat dissipation are extremely stringent. The quality of heat dissipation will directly affect the quality and service life of the product. Since most of the circuit boards on the market are traditional circuit boards, the circuit boards are an integrated sealed structure. When this type of circuit board is in use, the heat energy generated will accumulate in the circuit board, causing the temperature in the circuit board to continue to rise, which can easily cause the electronic components on the circuit board to be damaged at high temperatures. Therefore, it is necessary to improve and transform the heat dissipation performance of the circuit board.

When the refrigeration pipe 2 is turned on, the air in the shell 1 can be cooled. Two first interfaces 21 are provided at the front right side of the shell 1, and six second interfaces 22 are provided at the front right side of the shell 1. The second interface 22 is located on the rear side of the first interface 21. A first movable plate 3 is slidingly provided at the middle left side of the shell 1.

When the fan 4 is turned on, the refrigerated air can be blown away. A supporting mechanism 5 is provided inside the shell 1, and a fixing mechanism 6 is provided at the top of the shell 1.

[0041] The supporting mechanism 5 includes a supporting column 51, a first rotating shaft 52, a first movable rod 53, a first torsion spring 54, a first movable block 55 and a second movable plate 56.

A first rotating shaft 52 is rotatably provided between the upper parts of each group of support columns 51, and a first movable rod 53 is provided on the first rotating shaft 52. The left side of the first movable rod 53 is slidably connected with the first movable plate 3. A first torsion spring 54 is provided between the middle part of the front and rear sides of the first movable rod 53 and the support column 51 on the same side, and the first torsion spring 54 is wound around the first rotating shaft 52. A second movable plate 56 is slidably provided on the upper middle part of the inner side of the shell 1, and a slot is provided on the second movable plate 56. People can place the circuit board on the second movable plate 56 and insert the circuit board into the slot. First movable blocks 55 are welded on both the front and rear sides of the left side of the bottom of the second movable plate 56, and the lower part of the first movable block 55 is slidably connected with the first movable rod 53 on the same side.

[0042] The fixing mechanism 6 includes a fixing rod 61, a second movable block 62, a second torsion spring 63, a second movable rod 64 and a first magnet 65, see Figure 7 and Figure 8 As shown, fixed rods 61 are welded symmetrically on both the front and rear sides of the top of the shell 1, and a second movable block 62 is rotatably provided on the fixed rod 61. When the second movable block 62 contacts the circuit board, the circuit board can be clamped. A second torsion spring 63 is provided between the upper part of the fixed rod 61 and the second movable block 62 on the same side. The second torsion spring 63 is wound around the fixed rod 61 on the same side. A second movable rod 64 is slidably provided between the outer sides of the second movable blocks 62 on the same side longitudinally. First magnets 65 are provided on both the left and right sides of the front side of the top of the shell 1. When the second movable rod 64 moves forward, it will contact the first magnet 65 on the same side.

[0043] When people need to use the thick copper power circuit board with heat dissipation structure, first pull the second movable rod 64 forward to make the second movable rod 64 squeeze the second movable block 62 to rotate, and the second torsion spring 63 is deformed. When the second movable rod 64 contacts the first magnet 65, the first magnet 65 will attract the second movable rod 64, and then release the second movable rod 64, and then put the circuit board on the second movable plate 56, and then press the circuit board downward to squeeze the second movable plate 56 and the first movable block 55 to move downward, so that the first movable block 55 squeezes the first movable rod 53 to rotate, and the first torsion spring 54 is deformed, so that the first movable rod 53 squeezes the first movable plate 3 to move upward, and then pushes the second movable rod 64 to move backward, so that the second movable rod 64 is separated from the first magnet 65, so that the first magnet 65 does not attract the second movable rod 64, and then the second movable rod 64 is released, and the second torsion spring 63 is restored to its original state, and the second torsion spring 63 drives the second movable block 62 to reverse and reset, so that the second movable block 62 contacts the circuit board, so that the second movable block 62 clamps the circuit board, and at the same time, the second movable block 62 squeezes the second movable rod 64 to move backward and reset. When people need to use the circuit board, they connect the connecting wires to the first interface 21 and the second interface 22 respectively, and then the circuit board can be used. When the circuit board is working, when the circuit board is heated during operation, people can turn on the cooling tube 2 and the fan 4, so that the cooling tube 2 cools the air in the housing 1, and then the cold air is blown away by the fan 4, so that the cold air cools the circuit board, thereby dissipating the heat of the circuit board. When people no longer need to use the circuit board, they disconnect the connecting wires from the first interface 21 and the second interface 22 respectively, so that the circuit board stops working, and then turn off the cooling tube 2 and the fan 4. When people no longer need to use the thick copper power circuit board with a heat dissipation structure, they pull the second movable rod 64 forward again to squeeze the second movable block 62 When the second movable rod 64 is rotated, the second torsion spring 63 is deformed. When the second movable rod 64 contacts the first magnet 65, the first magnet 65 will attract the second movable rod 64 and then release the second movable rod 64. When the second movable block 62 is separated from the circuit board, the second movable block 62 releases the circuit board. At this time, the first torsion spring 54 returns to its original state, and the first torsion spring 54 drives the first movable rod 53 to reverse and reset, so that the first movable rod 53 squeezes the first movable plate 3 to move downward and reset. At the same time, the first movable rod 53 squeezes the first movable block 55 and the second movable plate 56 to move upward and reset, thereby driving the circuit board to move upward, and then the circuit board can be removed from the second movable plate 56.

[0044] Example 2

After the third movable plates 72 are rotated, the cold air in the shell 1 can be discharged outward. The third movable plates 72 block the right parts of the front and rear sides of the shell 1, and third movable rods 73 are welded on the right sides of the second rotating shafts 71. Fourth movable rods 74 are slidably provided between the right sides of the four third movable rods 73 in the same vertical direction. The upper side of the fourth movable rod 74 passes through the top of the shell 1, and second magnets 75 are provided on the lower right sides of the front and rear sides inside the shell 1. When the fourth movable rod 74 moves downward, it will contact the second magnet 75 on the same side.

[0046] When people need to discharge the cold air in the shell 1, they can press the fourth movable rod 74 to move downward, thereby squeezing the third movable rod 73 to rotate, causing the second rotating shaft 71 and the third movable plate 72 to rotate, so that the third movable plate 72 no longer blocks the right parts of the front and rear sides of the shell 1, and then the cold air is discharged outwardly through the right parts of the front and rear sides of the shell 1. When the fourth movable rod 74 contacts the second magnet 75, the second magnet 75 will attract the fourth movable rod 74, and then the fourth movable rod 74 is released. When the cold air in the shell 1 is completely discharged, the fourth movable rod 74 is pulled upward to move back to its original position, so that the fourth movable rod 74 is separated from the second magnet 75, so that the second magnet 75 does not attract the fourth movable rod 74. At the same time, the fourth movable rod 74 squeezes the third movable rod 73 to reverse and reset, so that the second rotating shaft 71 and the third movable plate 72 are reversed and reset, so that the third movable plate 72 blocks the right parts of the front and rear sides of the shell 1 again, and then the fourth movable rod 74 is released, so that it is convenient for people to discharge the cold air in the shell 1 outward.

[0048] When people need to turn on the refrigeration pipe 2 and the fan 4, they can rotate the counterweight 86, thereby driving the fourth rotating shaft 84 and the fifth movable plate 85 to rotate, so that the fifth movable plate 85 does not block the middle part of the support plate 81, and then release the counterweight 86. When the refrigeration pipe 2 and the fan 4 are turned on, the fan 4 will blow cold air onto the fourth movable plate 83, so that the cold air squeezes the fourth movable plate 83 to rotate, so that the fourth movable plate 83 does not block the inner right part of the shell 1, and then the cold air enters the inner right part of the shell 1, and then returns to the inner middle part of the shell 1 through the middle part of the support plate 81, so that the cold air circulates inside the shell 1. When people turn off the refrigeration pipe 2 and the fan 4, at this time, under the action of gravity, the fourth movable plate 83 is reversed and reset, so that the fourth movable plate 83 blocks the inner right part of the shell 1 again, and then the counterweight 86 is reversed and reset, thereby driving the fourth rotating shaft 84 and the fifth movable plate 85 to reverse and reset, so that the fifth movable plate 85 blocks the middle part of the support plate 81 again.

[0051] When the fan 4 is blowing the cold air, the dustproof net 92 will filter the cold air and leave the dust in the cold air on the dustproof net 92. When people take the circuit board away from the second movable plate 56, they can push the third movable block 101 to move to the right, and the second spring 103 is compressed to make the third movable block 101 release the support block 91, and then pull the support block 91 downward to move out. At this time, the support block 91 will squeeze the movable buckle 93 to move to the left, and the first spring 94 is compressed to make the movable buckle 93 release the support block 91.
