Definitions
- the invention relates to an arrangement with a power module having power semiconductor components and with a component, in particular with a heat sink.
- a power converter with such an arrangement and a vehicle with a power converter are also specified.
- the power module including substrate and base plate
- more efficient cooling can also take place here, which is directly related to the service life or performance of the semiconductor chips and thus of the entire power module.
- Power electronics variants are known that deal with a three-dimensional arrangement of the circuit or the modules employ. However, these all have in common that the power module is connected flat, ie not bent. In addition to these variants, there are other ways to achieve a three-dimensional arrangement.
- the circuit carrier usually consists of polyimide with a thickness between
- the circuit board can thus be used with curved surfaces, e.g. a curved radiator.
- a disadvantage is the limited copper conductor path thickness, which is only suitable to a limited extent for power electronic applications.
- a catalyst-filled polymer is melted at the later conductor track locations by means of a laser (e.g. CO2 laser) and the concentration of the catalyst, e.g. Palladium, increased.
- a subsequent electroless electroplating step can grow on the catalyst and thus strengthen the conductors.
- the polymer injection molding process results in a high degree of freedom in terms of geometries, e.g. curved surfaces.
- this method has the disadvantage that there is slow growth of the conductor tracks and only small layer thicknesses can therefore be produced.
- the object of the invention is to provide a solution that allows power semiconductor components to be reliably attached to curved surfaces, in particular of coolers.
- the invention results from the features of the independent claims.
- the dependent claims relate to advantageous developments and refinements. Further features, possible applications and advantages of the invention emerge from the following description.
- One aspect of the invention is to provide a novel solution for realizing curved power electronics which, on the one hand, can be constructed in a space-saving manner and, on the other hand, ensures high cooling.
- the invention claims an arrangement with at least one power module having power semiconductor components and with a component, in particular with a heat sink, where the component has a curved surface and the power module is arranged on the surface and is partially releasably connected to the construction.
- the power module can have a housing with internal punches, the punches being designed to be pressed onto the power semiconductors or onto a circuit carrier of the power module in the direction of the surface of the component.
- the power semiconductor components can be arranged on the circuit carrier.
- the housing can be non-positively fixed on the component by screws.
- the housing can be frictionally fixed on the component with a belt loop fixed by screws.
- the housing can be non-positively fixed on the component with clamps.
- several power modules with housings can be fixed in a force-locking manner on the component with a single strap loop or a shrink tube.
- the component can have a cylindrical shape and the belt loop can wrap around the component, the two ends of the belt loop being fixed in an anchorage on the component.
- an elastic first heat-conducting material can be arranged between the component and the power module.
- the housing can be filled with an elastic second heat-conducting material.
- the invention also claims a power converter, in particular a converter, with an arrangement according to the invention.
- a converter is referred to as a converter, which generates an alternating voltage with changed frequency and amplitude from an alternating voltage or direct voltage.
- Converters are often designed as AC / DC-DC / AC converters or DC / AC converters, an AC output voltage being generated from an AC input voltage or a DC input voltage via a DC voltage intermediate circuit and pulsed semiconductors.
- the invention also claims a vehicle, in particular an aircraft, with a converter according to the invention for an electric or hybrid-electric drive.
- a vehicle is understood to mean any type of locomotion or transport means, be it manned or unmanned.
- An aircraft is a flying vehicle.
- the aircraft has an electric motor supplied with electrical energy and a propeller which can be set in rotation by the electric motor.
- FIG. 1 shows a sectional view of an arrangement of a first exemplary embodiment
- FIG. 3 shows a sectional view of an arrangement of a third exemplary embodiment
- Fig. 5 is a block diagram of a converter with a
- a circuit carrier 4 On the underside of the power module 1 there is a circuit carrier 4 on which the power semiconductor components te 3 are arranged.
- the power module 1 is permanently pressed onto the curved surface of the component 2 by means of a suitable device or a suitable pressure ram.
- the topology or the curvature of the surface of the component 2 is also transferred to the circuit or the circuit carrier 4 of the power module 1 by the contact pressure.
- the circuit carrier 4 can be ceramic or organic in nature.
- the stamp 5.1 for pressing the power semiconductor components 3 can be designed in different variants and press directly or indirectly (e.g. with the help of a pressure compensation material) on the power semiconductor components 3 or on parts of the circuit carrier.
- the punch 5.1 can be integrated into a housing 5 or designed as an independent component.
- the stamp 5.1 can also be used for the electrical contacting of the circuit or as an additional option for heat dissipation on the top.
- the application of the necessary contact force can be ensured in the simplest case by screws 6 (Fig. 1), which the stamp 5.1 anpres sen.
- Fig. 5 shows a block diagram of a converter 12, in particular a converter, with a power module 1 according to the invention on egg NEN cooler 10 according to the Darstellun conditions of FIGS. 1 to 4.
- Fig. 6 shows an electric or hybrid-electric air Vehicle 14, in particular an aircraft, with a Stromrich ter 12 according to FIG. 5, which supplies an electric motor 15 with electrical energy.
- the electric motor 15 drives a propeller 16. Both are part of an electrical thrust generation unit.
