Description

Technical Field

[0001] This utility model relates to the field of heat sink technology, specifically a bendable heat sink. Background Technology

[0002] A heat sink is a device used for heat dissipation, typically made of a metal with good thermal conductivity, such as aluminum or copper. They effectively reduce the heat generated by electrical or electronic equipment by increasing the surface area in contact with air, preventing overheating. In electrical appliances, heat sinks play a crucial role in improving equipment operating efficiency and extending its lifespan.

[0003] Existing heat sinks are typically designed as straight plates, usually consisting of multiple fins welded onto a copper plate. However, when installing heat sinks, some electrical appliances have polygonal shapes, and the installation location of the heat sink also needs to be polygonal. Therefore, straight heat sinks are not convenient to fit the heat dissipation location of the appliance, resulting in poor applicability and making them unsuitable for installation in various situations. To address this, we propose a bendable heat sink. Utility Model Content

[0004] The purpose of this invention is to provide a bendable heat sink to solve the problem mentioned in the background art that the straight heat sink is not convenient to fit the heat dissipation position of polygonal electrical appliances.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bendable heat sink, comprising a mounting plate, a plurality of fins 1 and fin 2 are provided on the top of the mounting plate, a connector is provided on the rear side wall of the mounting plate, a fixing block is provided on the right side wall of the mounting plate, a positioning pin is embedded in the side wall of the fixing block, a rubber strip is fixedly connected to the side wall of the fixing block, a fixing piece is provided on the top of the fin 2, a nylon strap is fixedly connected to the side wall of the fixing piece, and a locking knob is provided on the top of the nylon strap.

[0006] Preferably, an extension piece is slidably fitted on one side wall of the fin, and a groove is formed on one top of the fin.

[0007] Preferably, the top of the extension sheet is fixedly connected to a sliding block that matches the slide groove, and the top of the sliding block is provided with a locking knob.

[0008] Preferably, a limiting block is provided at the top of the fin, and the limiting block is engaged with the top of the extension sheet.

[0009] Preferably, a metal strip is embedded inside the rubber strip, and the rubber strip is fitted to the side wall of the connector.

[0010] Preferably, the top of the nylon strip is machined with an elongated hole that matches the locking knob, and the top of the second fin has a shallow groove that matches the nylon strip.

[0011] Preferably, the mounting plate has bolt holes on its top and is rectangular in shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features a multi-segment mounting plate with connecting parts for rotational connection. The mounting plate can be bent by loosening the locking knob to fit a polygonal heat-dissipating device and be bolted in place. During this bending, the metal strip inside the rubber strip deforms in conjunction with the plate's bending. The locking knob, in conjunction with the nylon strap, slides as the mounting plate bends. Tightening the locking knob after bending locks the bending angle of the mounting plate, thus enabling the heat sink to be bent and installed to fit the polygonal heat-dissipating device more effectively, improving its applicability.

[0014] 2. After the heat sink is installed, the locking knob can be loosened to remove the locking of the sliding block. Then, the extension piece can be slid to the left along the groove of fin one to extend the extension piece. The extended extension piece can then transfer the heat of fin one and dissipate the heat outward, thereby increasing the overall heat dissipation area of ​​the heat sink and improving its heat dissipation efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Please see Figures 1-3 The diagram shows a bendable heat sink, including a mounting plate 100. Multiple fins 110 and 120 are tightly welded to the top of the mounting plate 100. The mounting plate 100, fins 110, and 120 are made of copper. A connector 130 is provided on the rear side wall of the mounting plate 100. The front section of the mounting plate 100 is rotatably connected to the connector 130 of the rear section of the mounting plate 100. A rotating column is rotatably connected inside the connector 130 on the rear side of the front section of the mounting plate 100. The right side wall of the mounting plate 100... A fixing block 140 is tightly welded together. A positioning pin 141 is embedded in the side wall of the fixing block 140. A rubber strip 142 is fixed to the side wall of the fixing block 140 by resin glue. A fixing plate 150 is provided on the top of the fin 120. A nylon strip 151 is fixed to the side wall of the fixing plate 150 by resin glue. A stainless steel strip is embedded inside the nylon strip 151, which can maintain the shape of the nylon strip 151 when it is bent and the locking knob 152 is tightened. A locking knob 152 is provided on the top of the nylon strip 151.

[0022] Specifically, an extension piece 111 is slidably fitted on the side wall of fin 110. Common thermal grease is applied to the gap between the extension piece 111 and fin 110. A groove 112 is provided on the top of fin 110.

[0023] Furthermore, a sliding block 113 that fits into the top of the slide groove 112 is tightly welded to the top of the extension piece 111, and a locking knob 114 is provided on the top of the sliding block 113.

[0024] Furthermore, a limiting block 115 is tightly welded to the top of fin 110, and the limiting block 115 is fitted to the top of the extension piece 111.

[0025] It is worth noting that a metal strip 143 is embedded inside the rubber strip 142. The metal strip 143 is made of thin stainless steel strips, and the rubber strip 142 fits into the side wall of the connector 130.

[0026] It is worth noting that the top of the nylon strip 151 is machined with an elongated hole that matches the locking knob 152, and the top of the fin 120 is provided with a shallow groove that matches the nylon strip 151.

[0027] In addition, bolt holes are provided on the top of the mounting plate 100, and the mounting plate 100 is rectangular.

[0028] Working principle: By setting up a multi-segment mounting plate 100 and using connectors 130 to rotate between the segments, the locking knob 152 can be loosened to allow the mounting plate 100 to be bent and fitted to the polygonal heat dissipation device for installation with bolts. At this time, the metal strip 143 inside the rubber strip 142 deforms in conjunction with the bending of the mounting plate 100. When the mounting plate 100 is bent, the locking knob 152 slides in conjunction with the nylon strap 151. After bending, tightening the locking knob 152 locks the bending angle of the mounting plate 100, thereby achieving heat dissipation. The heat sink is bent and installed in conjunction with the polygonal heat dissipation device, allowing the heat sink to fit the device better and improving its applicability. After the heat sink is installed, the locking knob 114 can be loosened to release the locking of the sliding block 113. Then, the extension piece 111 can be slid to the left along the sliding groove 112 of the fin 110 to extend the extension piece 111. The extended extension piece 111 transfers the heat from the fin 110 and dissipates the heat outward, thereby increasing the overall heat dissipation area of ​​the heat sink and improving its heat dissipation efficiency.
