Alternative Power

Vette, a global provider of thermal management solutions, has unveiled Aluma-Cop liquid cooling for insulated gate bipolar transistors (IGBT). The company’s liquid cooling flat tube design offers a smaller and lighter alternative to cool IGBT power semiconductors incorporated in demanding applications.

 

IGBTs are high-efficiency and fast-switching power semiconductor devices. They need to be cooled to ensure reliability in electric vehicles and hybrid cars. These devices are used to power the AC motors and generators linked to the car’s batteries. IGBT power semiconductor applications also feature power supplies and uninterruptible power supplies, variable speed refrigerators, air-conditioners, and digital amplifiers in high-end consumer audio systems.

 

Established in 2004, Vette Corp is a global thermal management solutions provider that specializes in resolving thermal challenges for leading OEM’s, operators and owners of computer, communications and industrial electronic equipment. The company has a growing IP portfolio, with design and applications engineering in Asia and North America.

Vette Corp’s vast solutions portfolio, design and manufacturing capabilities are complemented by world-class supply chain and customer service, thus ensuring lowest cost, highest quality, end-to-end solutions for complex thermal problems.

 

“What makes Aluma-Cop liquid cooling unique is how we designed the tube. The flat tube forms a larger, wider ‘cold’ surface area against the devices or modules that require cooling,” explained Vette’s North American Power Division President Chris Cutaia. “It has a cross-sectional aspect ratio of greater than four to one with internal integral forged fins creating a flow channel optimized for both fin pitch and fin height to width ratios. This achieves much greater cooling performance than typical designs that simply press a smooth bore round copper tube into an aluminum carrier block.”

 

Without using an aluminum carrier block, Aluma-Cop cooling solutions can offer cooling to an IGBT power semiconductor device. The IGBT semiconductor modules can be adjusted by just loosening clamps and moving the modules into a required position during the product assembly sequence. Vette’s Aluma-Cop tubes are connected through manifolds that are compatible with all sizes of IGBT power semiconductor applications.
