Definitions
- the invention relates to an electrical machine, preferably a three-phase generator for motor vehicles, with a rectifier unit according to the preamble of claim 1.
- a rectifier unit is usually arranged on the rear end face of the three-phase generator driven by the motor vehicle engine, which rectifies the three-phase AC voltage generated in the stator winding of the three-phase generator for charging an accumulator battery in the vehicle electrical system.
- the rectifier bridge circuit of the unit consists of several diode bridges, each with a plus diode and minus diode connected in series.
- the minus diodes are attached and contacted on the anode side on a common minus connection plate and the plus diodes are connected on the cathode side on a common plus connection plate, which are designed as minus or plus heat sinks.
- the free connection ends of the diodes are connected to the individual diode bridges connected together and each connected to a phase connection of the stator winding on the input side.
- the rectifier assembly has relatively large dimensions, so that only a small degree of freedom remains for the attachment of the rectifier assembly on the front side of the rear bearing plate.
- the end shield of the machine must be made of a good heat-conducting material, since a large part of the heat loss from the rectifier assembly is first dissipated by heat conduction to the end shield, in order to be dissipated there by radiation and convection from the cooling air flow of the rear air of the machine.
- due to the relatively large masses of the heat sinks there is the risk that small vibrations or shocks will occur between the rectifier parts and between them and the end shield. which can lead to interruptions in the rectifier bridge circuit.
- the aim of the present solution is to transfer the heat loss from the rectifier assembly to the cooling air of the machine in the most efficient manner in order to keep the dimensions of the rectifier assembly as small as possible.
- the electrical machine according to the invention with the characterizing features of claim 1 has the advantage over the prior art that the heat loss of the rectifier unit is essentially absorbed by the cooling air drawn in by the fan of the machine before it is absorbed by the heat loss of the machine, in particular is additionally heated by the stator winding of the machine. Due to the efficient cooling of the rectifier assembly, its dimensions can be reduced, so that this results in greater degrees of freedom when attaching the rectifier assembly to the end shield. The heat loss from the front connection plate of the
- Rectifier unit is discharged via a heat sink to the cooling air flowing in in the area of the bearing plate near the axis.
- Another advantage is that due to the small dimensions of the rectifier assembly, it is used in a window of the end shield, so that it reaches with its rear connection plate close to the fan blades of the rear fan of the machine in order to dissipate the heat loss there to emit cooling air flowing radially outward in strong flow.
- the rectifier assembly is combined in a bridge circuit to form a compact diode module, in which the minus and plus diodes of each diode bridge consist of semiconductor substrates, each with a connecting part inserted between them, between the plus and minus connection plates Form a stack.
- the stacks are arranged side by side between the two connection plates and their connection parts are led out side by side on a long side of the diode module.
- the winding ends of the stator winding can be connected directly, so that the additional switching connections previously required can be dispensed with, especially since these switching connections were previously mostly embedded in plastic, which represents a potential fire hazard in the event of short-circuits.
- the connecting parts on the long side of the diode module are angled so that their end sections are in a recess in the heat sink for connecting the stator winding to the outside protrude.
- the heat sink is semicircular and is screwed onto the end face of the end shield from the outside.
- it is advantageously provided on its outside facing away from the diode module with radially extending cooling fins arranged next to one another.
- the protective cap which is known per se and covers the end face of the end shield, in the area away from the axis from air outlet openings preferably distributed over the entire circumference of the protective cap, but are at least arranged above the heat sink.
- the star connections are arranged on the rear winding head of the machine with a star connection.
- This has the advantage that the star connection of the stator winding can also be moved away from the winding head into the connection connector, especially since the star point can then be connected in a simple manner via a further diode bridge of the diode module in order to utilize harmonics of the voltage generated in the stator winding.
- the heat sink is either attached to the plus connection plate or to the minus connection plate, ie screwed, welded or riveted.
- the rectifier assembly is fastened flat to the heat sink with the outside of its positive connection plate, the heat sink then being provided with a positive connection terminal for connecting the vehicle electrical system battery.
- the heat sink is with an electrically insulating intermediate layer on which the ground potential of the vehicle electrical system leading bearing plate attached.
- a heat-conducting material for example an aluminum oxide ceramic, is used for the electrically insulating intermediate layer, so that the lost heat can also be dissipated from the heat sink to the end shield as an additional heat sink.
- fastening holes are expediently provided in the heat sink, into which insulating sleeves are inserted, which receive the fastening screws of the heat sink.
- the outside of the minus connection plate is expediently connected flatly to a busbar, which extends as a ground connection on the inside of the bearing plate and over the opening and with it Is attached to the end shield.
- the rectifier assembly is attached flat to the heat sink with the outside of its Mmus connection plate, which in turn is attached to the bearing plate forming the ground potential in a current and heat conducting manner.
- Increased dissipation of the heat loss from the heat sink to the end shield as an additional heat sink can advantageously be achieved in that the heat sink rests flat on the end shield, preferably via a flow and heat-conducting intermediate layer.
- a heat-conducting intermediate layer i.a. a paste, glue or wax can be used.
- the heat sink can also be an integral part of the plus or minus connection plate.
- Intensive cooling of the exposed connection plate facing away from the heat sink can be achieved by
