Semiconductor power stacks require external cooling to prevent component failures due to overheating. Littelfuse makes several coolers that use water to ensure IGBTs, MOSFETs, fuses and other devices in power stacks remain within their nominal operating temperatures. Each cooler is designed to clamp securely against a capsule-type or rectangular power stack without damaging the semiconductor assembly. Each cooler is also designed to keep water flowing continuously while a power stack operates.
- Available with cooler thicknesses of 16 mm to 34 mm
- Available with bus bar thicknesses of 6.4 mm to 10 mm
- Net weight per cooler ranges from 400 g to 5.95 kg
- Quarter-inch BSPP (British Standard Parallel Pipe) hydraulic fittings
- Made from aluminum or copper
- Very flat (20 µm) and very smooth (0.8 µm) contact areas
- Designed for use in tandem and performance-tested with two or three coolers cooling a single semiconductor assembly
- International standard packages
