Description

Technical Field

[0001] This utility model relates to the field of electronic heat sink technology, and in particular to an aluminum electronic heat sink with high heat dissipation efficiency. Background Technology

[0002] Aluminum electronic heat sinks are heat dissipation devices specifically designed for cooling electronic devices. Their main material is aluminum or aluminum alloy. Due to the advantages of aluminum, such as good thermal conductivity, light weight, ease of processing, and low cost, aluminum heat sinks have been widely used in the field of electronic devices to dissipate the heat generated by chips such as CPUs and GPUs.

[0003] In existing aluminum electronic heat sinks, after the heat sink and electronic components are fixedly connected, heat is transferred from the electronic components to the heat sink. The fins enhance natural convection, allowing more heat to be dissipated into the air through natural convection, thereby achieving the purpose of heat dissipation. Because aluminum electronic heat sinks need to be in close and full contact with electronic components during operation, the size of aluminum electronic heat sinks is relatively fixed, which makes it impossible to flexibly adapt to the heat dissipation needs of different electronic devices. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation aluminum electronic heat sink, comprising a connecting frame, a first spring fixedly connected to the inner top wall of the front side of the connecting frame, a limit rod fixedly connected to the bottom of the first spring, the limit rod being located slightly above the inner front side of the connecting frame, a second spring fixedly connected to the inner right side of the connecting frame, a control strip fixedly connected to the left side of the second spring, a control groove being provided inside the control strip, the control strip being slidably connected to the connecting frame, a positioning groove being provided in the center of the inner front side of the connecting frame, a control block being slidably connected to the inner left side of the connecting frame, the control block being slidably connected to the control strip, and a clamping assembly being provided at the rear side of the connecting frame, the clamping assembly being used for quickly connecting the assembled heat sink and electronic components of different sizes.

[0009] Preferably, a base is fixedly connected to the center of the connecting frame, and the connecting frame and the base are riveted together.

[0010] Preferably, the two clamping blocks are slidably connected to the control frame, and machine oil is applied between the clamping blocks and the control frame.

[0011] Preferably, the limiting rod passes through the control groove, the positioning groove, and the connecting groove in sequence, and the control groove, the positioning groove, and the connecting groove are all engaged with the limiting rod.

[0012] Preferably, a plurality of fins are fixedly connected to the top of the base, and the plurality of fins are wavy fins.

[0013] This utility model has the following beneficial effects:

A first spring 3 is fixedly connected to the inner top wall of the front side of the connecting frame 1. A limit rod 2 is fixedly connected to the bottom of the first spring 3. The limit rod 2 is located inside the upper part of the front side of the connecting frame 1. A second spring 5 is fixedly connected to the inner wall of the right side of the connecting frame 1. A control strip 4 is fixedly connected to the left side of the second spring 5. A control groove 8 is opened inside the control strip 4. The control strip 4 is slidably connected to the connecting frame 1. A positioning groove 9 is opened in the center of the front side of the connecting frame 1. A control block 6 is slidably connected to the inner wall of the left side of the connecting frame 1. The control block 6 is slidably connected to the control strip 4. A clamping assembly is provided on the rear side of the connecting frame 1. The clamping assembly is used to quickly connect the assembled heat sink and electronic components of different sizes.

[0024] Specifically, the connecting frame 1 is used to fix the position of the first spring 3 and the second spring 5 and provide reaction force to the first spring 3 and the second spring 5. The first spring 3 is used to provide reaction force to the limit rod 2 to help the limit rod 2 reset. The second spring 5 is used to provide reaction force to the control bar 4 to help the control bar 4 reset. The connecting frame 1 is used to control the movement trajectory of the control bar 4 and the control block 6. The limit rod 2 moves inside the connecting frame 1. The control block 6 is used to drive the control bar 4 to move left and right.

[0025] Reference Figure 1 and Figure 4 The clamping assembly includes a control frame 15, which is located behind the connecting frame 1. Control arms 16 are rotatably connected to both the upper and lower sides of the control frame 15. Cylinders 17 are rotatably connected to the upper side of the lower control arm 16. The output end of the cylinder 17 is rotatably connected to the upper control arm 16. Clamping blocks 13 are rotatably connected to the right side of both control arms 16.

[0026] Specifically, the control frame 15 is used to fix the position of the control arm 16 and control the movement trajectory of the control arm 16. The cylinder 17 drives the left end of the control arm 16 to move in the opposite direction, and the right end of the control arm 16 drives the clamping block 13 to move in the opposite direction under the action of the outer frame.

[0027] Reference Figure 1 A slider 7 is fixedly connected to the right side of the connecting frame 1. The slider 7 is an I-shaped slider.

[0028] Specifically, the connecting bracket 1 is used to fix the position of the slider 7. The slider 7 is an I-shaped slider to facilitate sliding and fixation.

[0029] Reference Figure 1 The front side of the connecting frame 1 is provided with a slide groove 10, which is an I-shaped slide groove.

[0030] Specifically, when the slide groove 10 is an I-shaped slide groove, it is to facilitate the sliding of the slide bar 7 and to fix the slide bar 7.

[0031] Reference Figure 1 The connecting frame 1 has a base 11 fixedly connected to its center, and the connecting frame 1 and the base 11 are riveted together.

[0032] Specifically, the base 11 is used to fix the position of the connecting frame 1. The base 11 and the connecting frame 1 are riveted together because the surface after riveting is relatively flat, which is conducive to heat dissipation.

[0033] Reference Figure 4 The two clamping blocks 13 are slidably connected to the control frame 15, and oil is applied between the clamping blocks 13 and the control frame 15.

[0034] Specifically, the control frame 15 ensures that the clamping block 13 moves horizontally, and the oil is used for anti-wear lubrication.

[0035] Reference Figure 2 and Figure 3 The limiting rod 2 passes through the control groove 8, the positioning groove 9 and the connecting groove 14 in sequence, and the control groove 8, the positioning groove 9 and the connecting groove 14 are all engaged with the limiting rod 2.

[0036] Specifically, when the slider 7 is fully inserted into the slide groove 10, the control groove 8, the positioning groove 9 and the connecting groove 14 are fully aligned. The limit rod 2 will pass through the control groove 8, the positioning groove 9 and the connecting groove 14 in sequence through the reaction force of the first spring 3, thereby fixing the slider 7.

[0037] Reference Figure 1 The base 11 has multiple fins 12 fixedly connected to its top, and the multiple fins 12 are wavy fins.

[0038] Specifically, the base 11 is used to fix the position of the fins 12. The wavy fins can increase airflow, thereby improving heat dissipation efficiency.

[0039] Working principle: When different electronic components need to be accommodated, the corresponding number of heat sink modules are taken out, and the slider 7 of one heat sink module slides into the connecting bracket 1 of another heat sink module. During the movement of the slider 7 inside the slide groove 10, it will drive the control block 6 to move upward. The control block 6 will drive the control bar 4 to move to the right. When the slider 7 is completely slid into the slide groove 10, the control groove 8, the positioning groove 9 and the connecting groove 14 are completely aligned. At this time, the limit rod 2 is subjected to the reaction force of the first spring 3 and moves downward through the control groove 8 and the positioning groove 9, and finally gets into the connecting groove 14 to fix the slider. Article 7, in order to flexibly assemble heat sink modules of different numbers and shapes according to the heat dissipation requirements of different electronic devices, at this time it is necessary to quickly connect the assembled heat sink and electronic components. The cylinder 17 drives the left ends of the two control arms 16 to move in opposite directions through the connecting block 14, and the right ends of the control arms 16 move towards each other under the control of the control frame 15. At this time, the control arms 16 will drive the clamping block 13 to move towards each other. The clamping block 13 moves horizontally towards each other under the restriction of the control frame 15 to clamp the heat sink and electronic components, thereby achieving the rapid connection of the assembled heat sink and electronic components.
