DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] like Figure 1-Figure 6 As shown, this embodiment provides a heat pipe structure embodiment of a heat sink that is based on pre-riveting and is easy to position and weld.
[0026] A heat pipe structure of a radiator based on pre-riveting and convenient for positioning welding comprises a pre-riveting structure main body 1 and a heat pipe main body 2, a pressing structure 3 is arranged on the pre-riveting structure main body 1, the pressing structure 3 comprises a plurality of fixing frames 4 installed on the top of the heat pipe main body 2, a first slider 5 is slidably connected inside the fixing frame 4, a connecting plate 6 is fixedly installed on the top of the first slider 5, a pressing plate 7 is installed at one end of the connecting plate 6, a sliding groove 8 is provided on one side of the connecting plate 6, a second slider 9 connected to the pressing plate 7 is slidably connected inside the sliding groove 8, a fixing block 10 is fixedly installed on the top of the connecting plate 6, a bolt 11 connected to the second slider 9 is installed on the fixing block 10, and the fixing block 10 is pressed by the fixing block 11. The setting of the tightening structure 3 can compress the heat pipe body 2 when welding it, and further fix the heat pipe body 2. After the heat pipe body 2 is placed on the pre-riveted structure body 1, the bolt 11 is screwed down to make the second slider 9 drive the pressing plate 7 to move downward, and the first slider 5 is pushed to drive the connecting plate 6 to move left and right. At this time, the pressing plate 7 also moves with the connecting plate 6, and the pressing plate 7 can be moved to different positions to compress the heat pipe body 2. Therefore, when welding different positions of the heat pipe body 2, it can be compressed and fixed, so as to avoid the heat pipe from being deformed and warped due to the heat generated by welding during the welding process, and will not affect the quality of welding.
[0027] A plurality of fixing rods 12 are fixedly installed at one end of the bolt 11. The setting of the fixing rods 12 can increase the force-bearing area of one end of the fixing rods 12, thereby preventing the hand from loosening when the bolt 11 is tightened, thereby facilitating tightening or loosening the bolt 11.
[0028] The first slider 5 is provided with a plurality of mounting holes 13, inside of which a first spring 14 is fixedly installed, a locking ball 15 is fixedly installed at one end of the first spring 14, and the inner side of the fixing frame 4 is provided with a plurality of locking holes 16 used in conjunction with the locking balls 15. By setting the mounting holes 13, the first spring 14, the locking balls 15 and the locking holes 16, the locking balls 15 are squeezed and contracted to the inside of the mounting holes 13 when the first slider 5 is pushed. When the first slider 5 moves to the position where the pressure plate 7 needs to be tightened, the locking balls 15 are engaged with the locking holes 16 under the elastic action of the first spring 14, so as to fix the first slider 5, thereby preventing the displacement of the first slider 5 from causing the pressure plate 7 to be separated from the position where the heat pipe body 2 needs to be fixed, thereby affecting the welding quality of the heat pipe body 2.
[0029] The fixed frame 4 is provided with a plurality of balls 17 connected to the first slider 5. The setting of the balls 17 can reduce the friction between the first slider 5 and the fixed frame 4, so that the first slider 5 can move smoothly on the fixed frame 4 with minimum force, thereby reducing the jitter and shaking caused by sliding friction, and also reducing the wear of the fixed frame 4 and the first slider 5.
[0030] A plug rod 18 is movably installed on the connecting plate 6, and a second spring 19 connected to the connecting plate 6 is wound around the plug rod 18. A plurality of limiting holes 20 adapted to the plug rod 18 are provided on the fixed frame 4. Through the arrangement of the plug rod 18, the second spring 19 and the limiting holes 20, the plug rod 18 is lifted upward when the first slider 5 moves. When the first slider 5 moves to a suitable position, the plug rod 18 is released so that it is inserted into the inside of the limiting hole 20 under the elastic action of the second spring 19, which can further improve the stability of the first slider 5.
[0031] A magnetic plate 21 connected to the pre-riveted structure body 1 is fixedly installed at the bottom of the fixed frame 4, and limit blocks 22 are fixedly installed at both ends of the fixed frame 4. Through the arrangement of the magnetic plate 21 and the limit blocks 22, it is convenient to disassemble the clamping structure 3 after the welding of the heat pipe body 2 is completed, and the clamping structure 3 can be reused. At the same time, the limit blocks 22 can prevent the first slider 5 from falling out of the fixed frame 4 due to excessive force when sliding the first slider 5, thereby affecting the progress of welding.
[0032] The slots on both sides of the fixed frame 4 are arranged to be inclined. Through the inclined arrangement of the slots on both sides of the fixed frame 4, when the airflow passes through the inclined slot, due to the angle between the slot bottom and the pre-riveted structure main body 1, the speed and direction of the airflow will change. Therefore, this arrangement can guide the airflow, so that the heat dissipation effect of the heat pipe main body 2 is better.
[0033] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a heat pipe structure of a heat sink based on pre-riveting and convenient for positioning welding provided in this embodiment is as follows:
[0034] After the heat pipe body 2 is placed on the pre-riveted structure body 1, the bolt 11 is tightened to lower the second slider 9 to drive the pressure plate 7 to move downward, and the first slider 5 is pushed to drive the connecting plate 6 to move left and right. At this time, the pressure plate 7 also moves along with the connecting plate 6, and the pressure plate 7 can be moved to different positions to press the heat pipe body 2. Therefore, when welding different positions of the heat pipe body 2, it can be pressed and fixed, avoiding the heat pipe from deforming and warping due to the heat generated by welding during the welding process, and will not affect the quality of welding.
[0035] In summary, in the present embodiment, according to a heat pipe structure of a radiator which is convenient for positioning welding based on pre-riveting of the present embodiment, the force bearing area of one end of the fixing rod 12 can be increased by setting the fixing rod 12, so as to prevent the personnel from loosening their hands when tightening the bolt 11, thereby facilitating the tightening or loosening of the bolt 11. By setting the mounting hole 13, the first spring 14, the clamping ball 15 and the clamping hole 16, the clamping ball 15 is squeezed and contracted to the inside of the mounting hole 13 when the first slider 5 is pushed. When the first slider 5 moves to the position where the pressure plate 7 needs to be tightened, the clamping ball 15 is engaged with the clamping hole 16 under the elastic action of the first spring 14, so as to fix the first slider 5, so as to prevent the first slider 5 from shifting and causing the pressure plate 7 to be separated from the position where the heat pipe body 2 needs to be fixed, thereby affecting the welding quality of the heat pipe body 2. By setting the ball 17, the friction between the first slider 5 and the fixing frame 4 can be reduced, so that the first slider 5 can move smoothly on the fixing frame 4 with the minimum force, reducing the friction caused by sliding. The jitter and shaking caused by friction can also reduce the wear of the fixed frame 4 and the first slider 5. Through the arrangement of the insertion rod 18, the second spring 19 and the limiting hole 20, the first slider 5 lifts the insertion rod 18 upward when it moves. When the first slider 5 moves to a suitable position, the insertion rod 18 is released so that it is inserted into the limiting hole 20 under the elastic action of the second spring 19, which can further improve the stability of the first slider 5. Through the arrangement of the magnetic plate 21 and the limiting block 22, it is convenient to disassemble the clamping structure 3 after the welding of the heat pipe body 2 is completed, and the clamping structure 3 can be reused. At the same time, the limiting block 22 can prevent the first slider 5 from falling out of the fixed frame 4 due to excessive force when sliding the first slider 5, thereby affecting the progress of welding. Through the inclined arrangement of the notches on both sides of the fixed frame 4, when the wind flow passes through the inclined groove, due to the angle between the bottom of the groove and the pre-riveted structure body 1, the speed and direction of the wind flow will change, so this arrangement can guide the wind flow, so that the heat dissipation effect of the heat pipe body 2 is better.
