With a total of two patents to his name, Krien has demonstrated expertise and ingenuity in creating solutions that enhance the efficiency of heat exchange processes.

Latest Patents

Krien's latest patent revolves around a sophisticated exhaust gas heat exchanger design. This invention features a bundle of pipes that include both exhaust gas pipes and a bypass channel, all contained within a single housing. The structural design incorporates a first chamber that is cross-flown by a liquid coolant, while the bypass channel is situated in a second, separate chamber. The innovative layout leads into a common exhaust gas inlet and outlet area, which houses an exhaust gas valve actuated by a servo-drive. This valve is crucial as it directs the exhaust gas flow either through the pipe bundle or the bypass channel. Notably, the exhaust gas valve is equipped with a bending-resistant movable closing organ, designed as a pivoting semi-flap fixed to a drive shaft that sits perpendicular to the exhaust gas flow, ensuring optimal functionality and durability.
