CAD and EMSD win awards at 50th International Exhibition of Inventions of Geneva (with photo)

******************************************************************************************

A two-phase immersion cooling system for a high-performance computer workstation, jointly developed by the Civil Aviation Department (CAD) and the Electrical and Mechanical Services Department (EMSD), won the Prize of the Republic and Canton of Geneva and Gold Medal at the 50th International Exhibition of Inventions of Geneva, which was held between April 9 and 13 (Geneva time) in Geneva, Switzerland. This is a special award presented by the Government of the Canton of Geneva, which represents the governmental level of honour and recognition, marking the first time for departments of the Hong Kong Special Administrative Region Government to receive this prestigious award.

The exhibition was an annual grand event in the global invention community. It showcased approximately 1 050 inventions from around 35 countries and regions. An international panel of expert judges conducted detailed evaluations of the inventions and selected the winning entries. The advanced technology innovation, jointly developed by the CAD and EMSD, provides a highly efficient heat dissipation capability for the CAD's high-performance air traffic control tower simulator by immersing heat-generating computer components into a sealed container filled with a non-conductive cooling liquid. Heat dissipation is achieved through the vaporisation of the cooling liquid. It provides a more efficient energy saving system with an extended equipment life time compared with traditional air cooling. The experience gained from developing this new technology could serve as a valuable reference for broader applications and promotions across various fields.

Meanwhile, a Tracking Solution for Outdoor Activity Safety, also jointly developed by the CAD and the EMSD, won the Gold Medal with Congratulations of Jury prize at the exhibition.

The Director-General of Civil Aviation, Mr Victor Liu, said, "The CAD is committed to enhancing operational efficiency through innovative technologies. The awards are a recognition of our colleagues' professionalism and the outcome of cross-departmental innovation and co-operation."
