Custom Heat Sinks


Product Details
There are various products that need heat dissipation in life, so the heat sinks needed are also various. Regis can design and produce all kinds of heat sinks according to customers' needs; custom heat sinks can be broadly divided into air-cooled heat sinks and liquid-cooled heat sinks. The air-cooled heat sink can be roughly divided into spade tooth type heat sink, squeeze type heat sink, insert tooth type heat sink, zipper type tooth heat sink, etc. Liquid-cooled heat sinks include friction-welded liquid-cooled plates, brazed liquid-cooled plates, buried copper tube liquid-cooled plates, etc. Here is a brief introduction to the various custom heat sinks
Ⅰ)Introduction of shovel tooth heat sink
Shovel tooth heat sinks are machined from a single sheet of metal, usually made of aluminum or copper. At present, the main processing of the shovel tooth heat sink is carried out by special CNC shovel tooth equipment, which can effectively ensure the number of teeth, the distance between the teeth and the thickness of the teeth.
Ⅱ)Advantages of shovel tooth heat sink
The thickness and spacing of the teeth of the shovel tooth heat sink are largely influenced by the accuracy of the processing machinery, and the thickness and spacing of the teeth of the heat sink can be as small as 0.2mm. The size range of the shovel tooth heat sink currently available on the market is particularly large, with the smallest shovel tooth heat sink being 2mm in length and width, but the largest shovel tooth heat sink being 1.5m in length and width. Another advantage is that it does not require a mold for processing, as long as the corresponding thickness of the plate can be purchased on the market, it is very suitable for the production of small quantities of heat sinks, and the energy efficiency of heat dissipation is about 10-30% higher than that of the inserted tooth heat sink.

Ⅲ)Aluminum extrusion heat sink
 The maximum width of aluminum extrusion heat sink can be opened 600mm, and the height multiplier of leaf teeth can reach 22 times. From the perspective of mold processing and manufacturing, the extrusion mold is divided into: flat die and manifold die, generally hollow die, more use of manifold die. Aluminum extrusion type heat sink is very widely used, the manufacturing process is very mature, processing is also very convenient, the production cost is relatively low, high production efficiency, very suitable for mass production. The extruded heat sink is made of AL6063-T5, an aluminum alloy with a high thermal conductivity of 209 W/m-K.

Ⅳ)Socket heat sink
The main features of insert heat sink are small density and tooth spacing, high height and flexible width of leaf teeth, which can be well suited for various placement spaces, while the size of the heat sink can be customized and processed flexibly, making it the preferred heat sink for high-power devices. The connection between the leaf teeth and the base plate of the insert radiator is either riveted or bonded with epoxy resin or tin welding. Epoxy resin adhesive thermal conductivity 0.2-3W/m-K or so, large heat dissipation area, low cost, but the thermal conductivity effect is sometimes not so ideal. The thermal conductivity of solder paste: 67W/m-K, suitable for small size heat sink, can be used with heat pipe, the use of solder paste solder insert heat sink there is a major drawback, that is, the cost is more expensive.

V)  Zipper Tooth Heatsink
The zippered tooth heat sink is the ideal air cooling solution for high power forced convection cooling. Each leaf tooth of the zipper heat sink is stamped out by a separate punch and then snap-linked in one piece in the mold. This heat sink allows the number of teeth to be set for different application scenarios of the product. The fins are connected to the base plate through the heat pipe, and then the base plate is soldered to the heat pipe by tin soldering. The zipper fin heat sink is formed in one piece by continuous stamping die, which has high production efficiency and low processing cost. However, the pre-development of this type of heat sink requires a large amount of tooling costs, resulting in high pre-development costs

VI) Friction stirring welding type liquid cooling plate
Friction stirring welding type liquid cooling plate belongs to a kind of water-cooled plate, which is mainly used in new energy vehicles, wind power energy storage, high-power devices and other products. For high-power and heat source distribution irregular liquid-cooled plate. It is generally recommended to use machining + stir friction welding runner process to complete. This process is a CNC milling process in the base plate to customize the runner, the runner can be processed into the shape of heat dissipation teeth to increase the heat dissipation effect, and then use the stir friction welding welding seal, for high pressure conditions, high power density of the use of the environment is particularly suitable. The weld strength of the Friction Stir Welding water-cooled plate is equivalent to more than 95% of the base material, and the pressure resistance can reach 10 bar~30 bar.

Ⅶ) brazed liquid cooling plate
Brazed liquid cooling plate is widely used in heat exchange system, engineering machinery heat exchange, photovoltaic inverter, IGBT, energy storage power supply, supercomputing server, etc. Water cooling plate is machine-added, internal runner size and path can be freely designed, suitable for thermal management products with high power density, irregular layout of heat source and restricted space.

Ⅷ)Copper tube liquid cooling plate
Copper tube liquid-cooled plates are widely used in medical devices, instruments and equipment, industrial automation, inverters, rail transportation, wind power energy storage, high-power devices and other products. By CNC milling in the substrate processing copper tube slot, through the special rolling machine will be special copper tube rolling into the substrate tube slot, in the slot gap buried with epoxy resin thermal conductive glue, and then after the glue completely dry CNC processing is completed, and finally do the pressure test of air tightness.

(Ⅸ) Above is Regis can customize various heat sinks for customers' doors.
