A finned heatsink with adjustable spacing

Abstract

This utility model discloses an adjustable-pitch finned heat sink, including a support frame and heat dissipation pipes. An adjustment auxiliary mechanism is provided at the upper end of the support frame. The adjustment auxiliary mechanism includes a mounting bracket fixedly connected to the upper end of the support frame, and a control frame fixedly connected to one end of the mounting bracket. Finned bodies are slidably mounted on the outer side of the heat dissipation pipes. A sliding groove is provided inside the control frame. The adjustable-pitch finned heat sink of this utility model allows for adjustment of the spacing between finned bodies by pulling an adjustment rod, which slides within the sliding groove. The adjustment rod, via a limiting ring, drives the adjustment frame to move smoothly along the control frame, and the adjustment rod, via a connecting seat, moves the finned bodies. This facilitates changing the spacing between the finned bodies and adjacent groups of finned bodies, thus enabling adjustment of the spacing between the finned bodies to adapt to different heat dissipation requirements.

Description

Technical Field

[0001] This utility model relates to the field of fin heat dissipation technology, and in particular to a fin heat sink with adjustable spacing. Background Technology

[0002] Radiators are a common industrial component. Whether it is large equipment or small device, as long as there is energy conversion, heat will inevitably be generated. Therefore, radiators are needed to improve the heat dissipation effect and ensure that the device will not be affected by the heat concentration. Common radiators include multiple fins. The fins can transfer heat to the air to ensure the heat dissipation effect. When there are more and larger fins, the contact area between the fins and the air is larger, which can improve the heat dissipation effect of the radiator. Traditional finned heat sinks have some drawbacks. Because the distance between the heat dissipation fins cannot be adjusted, they cannot dissipate heat according to the actual heat situation, resulting in poor heat dissipation performance.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1-4As shown, an adjustable finned heat sink includes a support frame 1 and a heat pipe 2. An adjustment auxiliary mechanism 5 is provided at the upper end of the support frame 1. The adjustment auxiliary mechanism 5 includes a mounting bracket 51 fixedly connected to the upper end of the support frame 1. A control frame 53 is fixedly connected to one end of the mounting bracket 51. A finned body 52 is slidably mounted on the outer side of the heat pipe 2. A sliding groove 54 is provided inside the control frame 53. An adjustment rod 55 is slidably connected to the inner side of the sliding groove 54. A connecting seat 56 is fixedly connected to the lower end of the adjustment rod 55. A limit ring 57 is fixedly connected to the outer side of the adjustment rod 55 near the upper side of the sliding groove 54. An adjustment frame 58 is slidably connected to the outer side of the control frame 53. A limiting hole 59 is provided at the front end of the adjustment frame 58. A limiting hole 510 is provided at the front end of the control frame 53. A limit bolt 511 is threadedly connected to the inner side of the limiting hole 59.

[0015] In this embodiment, the upper end of the control rod 55 is fixedly connected to the control rod 512. The mounting bracket 51 is L-shaped. The lower end of the connecting seat 56 is fixedly connected to the upper end of the fin body 52. ​​The axis of the control rod 55, the connecting seat 56, the limiting ring 57, and the control rod 512 are on the same straight line. The lower end of the limiting ring 57 is in contact with the upper end of the control bracket 53. The control bracket 58 is U-shaped. The limiting hole 59 and the restricting hole 510 correspond to each other. The outer side of the limiting bolt 511 is threaded to the inner side of the restricting hole 510 near the rear side of the limiting hole 59. There are several sets of restricting holes 510.

[0016] Specifically, if it is necessary to adjust the spacing between the fin bodies 52, first unscrew the limiting bolt 511, causing the limiting bolt 511 to disengage from the limiting hole 510 and the limiting hole 59. Then, pull the control rod 512, causing the control rod 512 to drive the adjusting rod 55 to slide within the sliding groove 54. The adjusting rod 55 then drives the adjusting frame 58 to slide along the control frame 53 via the limiting ring 57. The adjusting rod 55 also drives the fin body 52 to move via the connecting seat 56, thus changing the spacing between the fin body 52 and the adjacent set of fin bodies 52. At this point, the limiting hole 59 corresponds to a new set of limiting holes 510. Then, screw the limiting bolt 511 from the limiting hole 59 into the new set of limiting holes 510. The control rod 55 is confined within the sliding groove 54, thereby confining the fin body 52 and adjusting the spacing between the fin bodies 52. This allows the spacing between the fin bodies 52 to adapt to different heat dissipation requirements. By pulling the control rod 55, the control rod 55 slides within the sliding groove 54, and the control rod 55 moves smoothly along the control frame 53 via the limit ring 57. The control rod 55 also moves the fin body 52 via the connecting seat 56, thus facilitating the change of the spacing between the fin body 52 and an adjacent set of fin bodies 52. This completes the adjustment of the spacing between the fin bodies 52, allowing the spacing between the fin bodies 52 to adapt to different heat dissipation requirements.

[0017] In this embodiment, the heat pipe 2 is installed inside the support frame 1. The lower end of the support frame 1 is fixedly connected to the fixing frame 3. One end of the fixing frame 3 is fixedly connected to the support base 4. The support base 4 is located below the fin body 52. ​​The fixing frame 3 is L-shaped. There are two sets of support frame 1, heat pipe 2 and fixing frame 3.

[0018] Specifically, the support base 4 is placed on the ground, and the heat pipe 2 is connected to the external device, so that the coolant in the heat pipe 2 can dissipate heat to the outside through the fin body 52.

[0019] Working principle: In use, first place the support base 4 on the ground, then connect the heat pipe 2 to the external device, so that the coolant in the heat pipe 2 can dissipate heat to the outside through the fin body 52. ​​If it is necessary to adjust the spacing between the fin bodies 52, first unscrew the limit bolt 511, so that the limit bolt 511 is disengaged from the limiting hole 510 and the limiting hole 59. Then pull the control rod 512, so that the control rod 512 drives the adjustment rod 55 to slide in the sliding groove 54, and the adjustment rod 55 drives the adjustment frame 58 to slide along the control frame 53 through the limit ring 57. The adjustment rod 55 drives the fin body 52 to move through the connecting seat 56, so that the spacing between the fin body 52 and the adjacent set of fin bodies 52 changes. At this time, the limiting hole 59 corresponds to the new set of limiting holes 510. Then, the limit bolt 511 is pulled back to its original position. By screwing bolt 511 from the limiting hole 59 into a new set of limiting holes 510, the adjusting rod 55 can be limited within the sliding groove 54, thereby limiting the fin body 52 and adjusting the spacing between the fin bodies 52. This allows the spacing between the fin bodies 52 to adapt to different heat dissipation requirements. By pulling the adjusting rod 55, the adjusting rod 55 slides within the sliding groove 54, and the adjusting rod 55 moves smoothly along the control frame 53 via the limiting ring 57. The adjusting rod 55 also moves the fin body 52 via the connecting seat 56, thus facilitating the change of the spacing between the fin body 52 and the adjacent set of fin bodies 52. This completes the adjustment of the spacing between the fin bodies 52, allowing the spacing between the fin bodies 52 to adapt to different heat dissipation requirements.
