Patent number: 11910579Abstract: A conversion device converts an input power into an output power, and gives rise to a power loss. The conversion device is cooled by a coolant circuit in which a coolant flows. A monitoring device determines, using operating data of the conversion device and/or of the coolant circuit, a flow velocity of the coolant and compares the flow velocity with a limit velocity. If the flow velocity reaches or exceeds the limit velocity, the monitoring device resorts to a special reaction. As long as the flow velocity does not reach the limit velocity, the monitoring device resorts either to no reaction or to a normal reaction that is not the same as the special reaction. The monitoring device determines the flow velocity by using a quantity of heat that is to be removed by the coolant per unit time, a local temperature of the conversion device, and an inflow temperature.Type: GrantFiled: November 25, 2019Date of Patent: February 20, 2024Assignee: Siemens AktiengesellschaftInventors: Ingolf Hoffmann, Horst Geyer, Abderrahim Chahid
