Abstract
A cooling device for an arrangement with at least one electric component, particularly power electronics (1), for a vehicle, wherein the arrangement can be cooled by a fluid (2) using the method of evaporative cooling, includes a heat engine (4), in particular a steam turbine or a displacement machine for expanding fluid that is evaporated during evaporative cooling.
Claims10
A cooling device for a vehicle comprising:
- a pressure-tight housing (3) having an upper shell;
- a condenser (8);
- an arrangement disposed within said housing including at least one electric component;
- a fluid (2) within said housing for cooling said electric component by evaporative cooling thereby generating evaporated fluid;
- and
- a turbine (4) disposed within the upper shell of said housing for expanding said evaporated fluid and for dividing a high pressure side of the fluid vapor from a low pressure side of the fluid vapor and for extracting energy from said vapor;
- said housing having a fluid discharge for conveying said expanded fluid to said condenser (8);
- wherein said arrangement comprises a plurality of electrical components;
- wherein the fluid has an electrical conductivity of no more than 10−6 (Ωm)−1 at 20° C. and substantially electrically insulates said electric components of said arrangement from one another;
- a feed pump (10) driven by said turbine feeds at least partially condensed fluid to said arrangement including said at least one electric component;
- and
- wherein said cooling device is independent of a cooling water cycle of the vehicle.
