Claim 5:
6. A computer program product for a monitoring device of a conversion device, the conversion device giving rise to a power loss and cooled with a coolant flowing in a coolant circuit, the computer program product embodied on a tangible, non-transitory computer readable medium, the computer program product comprising a computer program with machine code, wherein when the machine code is executed by the monitoring device, the monitoring device carries out the steps of:
receiving as a measurement value an inflow temperature at which the coolant is supplied to the conversion device,
determining a flow velocity at which the coolant flows in the coolant circuit based on operating data of the conversion device and/or the coolant circuit, a quantity of heat to be removed per unit of time by the coolant known to the monitoring device, a local temperature of the conversion device known to the monitoring device, and the inflow temperature,
comparing the determined flow velocity with a limit velocity,
resorting to a special reaction when the determined flow velocity reaches or exceeds the limit velocity, and
resorting to either no reaction at all or to a normal reaction that is not the same as the special reaction as long as the determined flow velocity does not reach the limit velocity.
