Patent No. EP3859260 (titled "A Plate Heat Exchanger") was filed by Alfa Laval Vicarb on Jan 29, 2020. The application was issued on Jun 21, 2023.
A plate heat exchanger with improved sealing arrangement, comprising a top head, bottom head, four side panels, and four corner girders forming a sealed enclosure around a stack of heat transfer plates. The enclosure is sealed by a continuous segmented gasket assembly, comprising multiple graphite segments, located in a groove between the side panels and corner girders, top head, and bottom head. The gasket assembly is designed to maintain its sealing performance even after decompression, providing a reliable and cost-effective sealing solution for high-pressure applications.
