New high performance cooling aggregates LA HPK …


Company Fischer Elektronik GmbH & Co. KG extends their wide programme of cooling aggregates by further high performance cooling aggregates of series LA HPK. High performance cooling aggregates are used for heat dissipation of greater power losses and the need for bigger semiconductors mounting surfaces. Double-sided opposing thick base plates ensure a good heat splay and simultaneously serve as a mounting surface for the electronic components to be cooled. The overall concept consists of single cooling fins which are pressed together to each fin end by a special pressfit geometry and are therefore thermotechnically optimal assembled. The inner fin tunnel is built by closely linked grooved cooling fins. Compared to straight fins the waived fin structure additionally realizes an efficiency improvement in terms of heat dissipation. With help of this surface structure a more turbulent flow is realized in the air channel to reach a better heat transfer from the fins to the air. The manufacturing process as well as the different fin heights allow a flexible design of the aluminium basic body. As a standard the dimensions 306 x 70 mm are offered for five axial fans, 330 x 90 mm for four axial fans, 282 x 110 mm for three axial fans and 240 x 129 mm for two axial fans. Each profile length of the high performance cooling aggregates is appropriately customised for the customer or specially produced according to the customer specific requirements. Furthermore the mentioned basic profiles are optionally orderable with or without airflow chamber for flow optimization. The underlying modular concept assures a mechanical and thermally perfect solution depending on the application. Additionally mechanical treatments, special designs or surface treatments are realized according to the customer’s specifications.
