Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation strip application technology, and in particular to an aluminum alloy heat dissipation strip and its spraying fixture. Background Technology
[0002] Aluminum alloy heat sinks are widely used in electronics and electrical appliances due to their excellent heat dissipation performance. During the production of aluminum alloy heat sinks, a spray coating process is usually required to improve their corrosion resistance and aesthetics.
[0003] Currently, heat sinks are typically installed in a protruding position, which encroaches on the heat dissipation space of electronic devices during installation, increasing manufacturing costs. Furthermore, the independent placement of multiple heat sinks results in low strength during use, leading to bending and damage. In addition, existing mounting structures are fixed during heat sink processing and painting, with no adjustable spacing between suspension parts. They can only accommodate one type of aluminum alloy heat sink, resulting in poor versatility. Moreover, the heat sinks are prone to shaking during painting, leading to uneven coating and affecting quality. Furthermore, existing mounting systems are ineffective at positioning the heat sinks, causing them to easily detach and pose a safety hazard.
[0004] Therefore, this utility model proposes an aluminum alloy heat sink strip and its spraying fixture. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an aluminum alloy heat sink strip and its spraying fixture, so as to solve the problems of low strength of heat sink strip, large installation space occupation, poor versatility of its fixture, poor spraying effect due to easy shaking of heat sink strip, and easy detachment of heat sink strip in the prior art.
[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing an aluminum alloy heat sink and its spraying fixture, including a heat sink body, wherein a groove is provided on the top of the heat sink body, and multiple heat sinks are uniformly fixedly connected inside the groove for heat dissipation treatment of the entire heat sink.
[0007] The bottom of the heat sink body has side grooves on both sides, which facilitates the inward retraction of the mounting holes and reduces the space occupied by outward extension during installation and fixing. The two side grooves also have mounting holes near the end face for hanging and installing the heat sink body.
[0008] The present invention is further configured such that the tops of the plurality of heat sinks are flush and reinforced with crossbars between them, and the plurality of crossbars are distributed alternately.
[0009] The above technical solution facilitates the use of multiple reinforcing crossbars to strengthen the heat sink, preventing it from bending and being damaged during use.
[0010] A spraying fixture for aluminum alloy heat sinks includes a hanging rod. Multiple adjusting brackets are uniformly sleeved on the outer wall of the hanging rod. Positioning components are bolted to the circumferential end faces of the multiple adjusting brackets. The heat sink body is engaged with the positioning components through mounting holes on both sides, and is used to hang the heat sink body for spraying operations.
[0011] The present invention is further configured such that: a hanger is fixedly connected to the top of the hanging rod, and the cross-section of the hanger is C-shaped; an installation groove is provided on the outer wall of the hanging rod, and a rubber pad is installed inside the installation groove.
[0012] The above technical solution facilitates the hanging rod to be hung and fixed in position via the hanger, and the rubber pad inside the mounting groove facilitates the locking and fixing of the adjustment frame in position.
[0013] The present invention is further configured such that: the adjusting frame includes a fixing sleeve sleeved on the outer wall of the hanging rod, a locking screw is threaded through the middle of the outer wall of the fixing sleeve, the locking screw passes through the fixing sleeve and its end thread is embedded in the inside of the rubber pad, a plurality of extension rods are uniformly fixedly connected to the outer wall of the fixing sleeve in the circumferential direction, a reinforcing rod is fixedly connected to each adjacent extension rod, and a positioning component is bolted to the end face of each extension rod.
[0014] The above technical solution facilitates sliding on the hanging rod by fixing the sleeve, and the locking screw is inserted into the rubber pad through the thread of the fixing sleeve, thereby fixing the entire adjustment frame. Furthermore, the extension rod can remain firm under the action of multiple reinforcing rods.
[0015] The present invention is further configured such that: the positioning component includes a U-shaped frame, a positioning block is fixedly connected to one inner wall of the U-shaped frame, and a locking rod is slidably connected through the other inner wall corresponding to the positioning block, and the locking rod is inserted into the mounting hole in cooperation with the positioning block; an adjusting nut and a spring are sequentially threaded to the outer wall of the locking rod, and a limit block is fixedly connected to the end face of the locking rod.
[0016] The above technical solution involves pressing the locking rod to cause the limiting block to pull the spring. Then, one of the mounting holes on the heat sink body is aligned with the positioning block, and the other mounting hole is aligned with the locking rod. The locking rod is released, and the spring's restoring force is used to drive the locking rod to insert into the mounting hole through the limiting block, thereby achieving the positioning and hanging of the heat sink body.
[0017] The present invention is further configured such that: the adjusting nut is away from the inner wall of the U-shaped frame, and the two ends of the spring are respectively engaged with the outer wall of the U-shaped frame and the limiting block.
[0018] The above technical solution facilitates the locking rod to slide on the U-shaped frame by pulling the spring through the limiting block when the locking rod is squeezed by the heat sink body, and at the same time, a certain stroke limit is achieved under the action of the adjusting nut.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0030] like Figure 1 and Figure 2 As shown, an aluminum alloy heat sink includes a heat sink body 1. The top of the heat sink body 1 has a groove, and multiple heat sinks 11 are uniformly fixedly connected inside the groove for heat dissipation of the entire heat sink. The tops of the multiple heat sinks 11 are flush, and reinforcing crossbars are provided between them. The multiple reinforcing crossbars are staggered to facilitate the reinforcement of the heat sinks 11 with multiple reinforcing crossbars and prevent them from bending and being damaged during use.
[0031] Side grooves 12 are provided on both sides of the bottom of the heat sink body 1, which facilitates the inward retraction of the mounting holes 13 and reduces the space occupied by outward extension during installation and fixing. Mounting holes 13 are provided on both side grooves 12 near the end face for hanging and installing the heat sink body 1.
[0032] like Figure 3 and Figure 5 As shown, a spraying fixture for aluminum alloy heat sink strips includes a hanging rod 2. A hanger 21 is fixedly connected to the top of the hanging rod 2, and the cross-section of the hanger 21 is C-shaped. An installation groove 22 is provided on the outer wall of the hanging rod 2, and a rubber pad 23 is installed inside the installation groove 22 to facilitate the hanging rod 2 to be hung and fixed in position by the hanger 21. The rubber pad 23 inside the installation groove 22 facilitates the locking and fixing of the adjustment frame 3 in position.
[0033] like Figure 3 and Figure 5As shown, multiple adjusting frames 3 are evenly fitted onto the outer wall of the hanging rod 2. Each adjusting frame 3 includes a fixing sleeve 31 fitted onto the outer wall of the hanging rod 2. A locking screw 32 is threaded through the middle of the outer wall of the fixing sleeve 31. The locking screw 32 passes through the fixing sleeve 31 and its end thread is embedded in the interior of the rubber pad 23. Multiple extension rods 33 are evenly fixedly connected to the outer wall of the fixing sleeve 31 in the circumferential direction. Each of the multiple extension rods 33 is fixedly connected to a reinforcing rod 34. The end faces of the multiple extension rods 33 are bolted to positioning components 4, which facilitates sliding on the hanging rod 2 through the fixing sleeve 31. The locking screw 32 passes through the fixing sleeve 31 and is threaded into the interior of the rubber pad 23, thereby fixing the entire adjusting frame 3. Under the action of the multiple reinforcing rods 34, the extension rods 33 can remain firm.
[0034] like Figure 3 and Figure 4 As shown, positioning components 4 are bolted to the circumferential end faces of multiple adjusting brackets 3. The heat sink body 1 is engaged with the positioning components 4 through the mounting holes 13 on both sides for hanging the heat sink body 1 for spraying operations. The positioning components 4 include a U-shaped bracket 41. A positioning block 42 is fixedly connected to one inner wall of the U-shaped bracket 41, and a locking rod 43 is slidably connected to the other inner wall corresponding to the positioning block 42. The locking rod 43 is inserted into the mounting hole 13 in cooperation with the positioning block 42. An adjusting nut 44 and a spring 45 are sequentially threaded onto the outer wall of the locking rod 43. The adjusting nut 44 is away from the inner wall of the U-shaped bracket 41, while the two ends of the spring 45 are engaged with the outer wall of the U-shaped bracket 41 and the limiting block 46, respectively. This allows the locking rod 43 to slide on the U-shaped frame 41 when it is pressed by the heat sink body 1. The locking rod 43 slides on the U-shaped frame 41 by pulling the spring 45 through the limiting block 46. At the same time, the adjusting nut 44 limits the travel of a certain distance. The end face of the locking rod 43 is fixedly connected to the limiting block 46. Pressing the locking rod 43 causes it to pull the spring 45 through the limiting block 46. Then, one of the mounting holes 13 of the heat sink body 1 is aligned with the positioning block 42, and the other mounting hole 13 is aligned with the locking rod 43. The locking rod 43 is released, and the spring 45's return force drives the locking rod 43 to be inserted into the mounting hole 13 through the limiting block 46, thereby achieving the positioning and hanging of the heat sink body 1.
[0035] In use, the processed heat sink body 1 is aligned with the positioning block 42 through one of the mounting holes 13, and the other mounting hole 13 corresponds to the locking rod 43. The locking rod 43 is released, and the spring 45's return force drives the locking rod 43 to be inserted into the mounting hole 13 through the limiting block 46, thereby positioning and hanging the heat sink body 1. The heat sink body 1 is then installed and fixed through the mounting holes 13 at both ends. The entire hanging rod 2 is then stably hung in the spraying area by the hanger 21 to perform the spraying operation. Finally, during installation, multiple heat sinks 11 are used to quickly dissipate the heat transferred by the heat sink body 1. At the same time, the reinforcing crossbars set between the heat sinks 11 can increase the stability between the heat sinks 11 to ensure the service life of the entire system.
