Abstract
A device which is used to cool the power electronics of a vehicle, by circulating a liquid through a cooling circuit which is mounted under a plate bearing the power electronics. According to the invention, the cooling circuit can include deflectors and/or turbulators in order to increase the exchange coefficient between the cooling circuit and the cooling liquid. The invention also relates to a method of producing the device.
Claims21
