Title: Walter Georg Angelis: Innovator in Cooling Technologies

Introduction: Walter Georg Angelis is a notable inventor hailing from St. Georgen, Germany. With an impressive portfolio of 7 patents, he has made significant contributions to the field of cooling technologies, particularly in the semiconductor industry.

Latest Patents: Among Walter's latest patents are innovative methods and arrangements for cooling substrates, especially semiconductors. One of his notable patents describes a method wherein a refrigerant is compressed in a refrigerating circuit, then condensed in a condenser, and subsequently expanded through a throttle valve. This expanded refrigerant, in the form of wet vapor, is directed to an evaporator that enjoys thermal contact with the substrate. This cooling process operates analogously to liquid cooling methods but delivers a higher mean logarithmic heat transfer temperature difference, enabling lower substrate temperatures and improving heat transition coefficients due to the wet vapor state of the refrigerant.

Another significant patent of his includes a novel apparatus that comprises a heat exchanger and an equalizing vessel for accommodating changes in coolant volume. This apparatus features an inflow to deliver coolant, an outflow for discharging coolant, and an equalizing vessel equipped with a flexible membrane to adapt to volume changes in the coolant. The vessel consists of two chambers, enhancing liquid communication with the heat exchanger's inflow and outflow, respectively, and is also equipped with a filter to maintain coolant purity.

Career Highlights: Walter has notably worked for companies like Ebm-papst St. Georgen GmbH & Co. KG and Papst Licensing GmbH & Co. KG. His roles at these organizations have allowed him to develop and refine his innovative cooling technologies, contributing to advancements in thermal management solutions.

Collaborations: Throughout his career, Walter has collaborated with several esteemed professionals, including Siegfried Seidler and Wolfgang Laufer. Their teamwork has undoubtedly fostered creativity and innovation in their respective projects.

Conclusion: Walter Georg Angelis stands out as a significant figure in the realm of innovations related to cooling technologies. With his wealth of knowledge and a dedicated career marked by collaboration and advancement, he continues to influence the field, particularly in semiconductor cooling solutions.
