A new method of manufacturing high ratio air-cooled extruded aluminum heat sinks has been announced by Sapa Extrusions North America. The extruded aluminum products manufacturer claims that heat sinks created using the new method are approximately eight percent more thermally efficient than the industry standard.
“The patent-pending method utilizes a modular concept that enables maximum flexibility with fin geometry, fin ratio and heat sink footprint. Not only does this method allow for the production of large-scale heat sinks up to 20 inches in width, it is also well-suited for serial production, making these types of heat sinks a competitive product in the marketplace,” the company said.
“This has been an exciting process, as we’re now able to achieve heat sink ratios in excess of 40:1, where we were previously restricted to ratios of 16:1 based on extrusion limitations,” Steve Jackson, business development manager of thermal management at Sapa Extrusions NA, said. “As a result, we’re able to offer customers an improved product that will provide cost savings, a decrease in lead time and a solution that meets a range of requirements.”
The company reportedly plans to use the new method to manufacture heat sinks for the power and LED street light markets.
