Compact IC coolers combine bracket fans & heat sinks

Jaro Thermal has released a range of powerful ‘fan-to-sink’ IC coolers, for use in low-profile applications including PCMIA, PCI Express cards, blade servers and HOT CHIP sets. The design of these IC coolers combines natural and forced-air convection by embedding a bracket fan into a heat sink design, ranging in sizes from 35x35mm to 52x52mm, with heights from 8 to 12mm.

To further enhance cooling capacity, these IC coolers use universal mounts and a thermal adhesive pad, ensuring complete surface contact with the heat source. These coolers minimise installation time because they use push-pins for mounting on the board. The push-pins are also designed to fit universal LGA socket types.

The thermal adhesive pad adds mechanical strength to the bond between the heat sink and the heat source, and also eliminates air (caused by incomplete surface contact) from the interface area. This is extremely important because the air acts as an insulator, impeding the heat transfer from the heat source to the heat sink.

The IC coolers are more commonly available with an aluminium heat sink frame, but they can be customised with a copper heat sink frame, depending upon the cooling capacity needed for an application.
