Novel Heat sink Design for telecom Power supply products

Ascom Energy Systems has minimised the size of its new FR 48V 600W high-frequency switched-mode telecom power supply range and optimised the cooling within each unit using an innovative space-saving circular aluminium heat sink. The novel heat sink design was developed using Flotherm – the industry-leading thermal analysis software. Designed and simulated prior to the prototyping stage, the new heat sink guides air from a closely sited fan through curved channels rather than over conventional fins or pins. Flotherm was used to analyse the airflow and match the shape of the fins with the swirl from the fan, increasing the overall efficiency of the cooling device.
