The new metal-to-metal bonded heat sink strength averages 657 pounds per inch with a much tighter, more controllable, deviation in the process. We developed several bonding techniques via our own technical innovations and these include highly conductive thermal epoxy bonding, brazing, and soldering so as to greatly enhance the reliability and stability of cooling and avoid any potential risk. California Machine Specialties has provided machined parts, assemblies, heat-sinks, and manufacturing solutions to the Bolted Assemblies, Heat Sinks, welded and brazed Assemblies, Heat Sinks, thermally bonded fins, Bolted Assemblies, CNC Milling, Precision Machining California, Heat-Sinks, Machining of extruded heat-sinks. They also make it possible to use other metals, such as copper, which have greater thermal conductivity but are not as readily extruded as aluminum. In the current electronics industry, heat sinks are used extensively to provide cooling for electronics components. com including Heat Technology Inc. 12 Aluminum High Power Bonded Fin Heat Sink Assembly for Natural or Forced Air Convection Product Description : Fan ready for forced convection cooling Will accept any standard 105mm muffin fan Terminal block ready for fan wiring Fins are high grade 1100-H14 series aluminum over 99 pure aluminum. The pins can be cylindrical, elliptical or square. The increased fin count of bonded fin heat sinks is the result of a tightly controlled assembly technique, allowing fin manufacture as a process independent from base extrusion. 023( 4 A) 0 1(Pr) 4. Heat Sink Sizing Calculations In order to calculate the heat transfer characteristics of the heat sink the convection coefficient (h) must be calculated. Specific structure and size that appropriate for the applied equipment and required heat load to carry is a must. As the amount of power dissipation in the device increases, the size of the heat sink must increase to allow more surface area to be exposed to the ambient. Suzhou Remgar Metal Manufacturer Co. The process of making a heat sink is often by extrusion, cold forging, pressed fin, or bonded fins. The fins are then bonded to a base with thermally conductive epoxy, brazing, welding, or similar metallurgical bonds, to create a heat sink. Fin height, fin thickness and fin density can be used in countless combinations to get the performance you the customer deserves.
