Frameless cooling module

Abstract

A heat exchanger adapted to be coupled with a platform is disclosed. The heat exchanger comprises two or more core units having an upper surface and a lower surface, the lower surface of each core unit being fixed to the platform. The heat exchanger further includes a plate disposed along the upper surface of the core units, the plate having a plurality of bend enhancement regions and a plurality of holes, each bend enhancement region being placed at a predetermined distance from the nearest adjacent holes, and a plurality of spacers interposed between the plate and the upper surface to couple the plate to the upper surface, the plurality of spacers adapted to provide offset between the plate from the core units. During operation of the heat exchanger, each bend enhancement region is configured to facilitate flexibility of the plate to accommodate any uneven expansion of the core units.

What is claimed is: 
     
         1 . A heat exchanger adapted to be coupled with a platform, the heat exchanger comprising:
 two or more core units having an upper surface and a lower surface, the lower surface of each core unit being fixed to the platform;   a plate disposed along the upper surface of the core units, the plate having a plurality of bend enhancement regions and a plurality of holes, each bend enhancement region being placed at a predetermined distance from the nearest adjacent holes; and   a plurality of spacers interposed between the plate and the upper surface to couple the plate to the upper surface, the plurality of spacers adapted to provide offset between the plate from the core units;   wherein, during operation of the heat exchanger, each bend enhancement region is configured to facilitate flexibility of the plate to accommodate any uneven expansion of the two or more core units.
