Definitions
- the cooling tube assumes a predetermined, defined position in the receiving area of the groove, in which the surface contact mentioned is present. On the one hand, this reduces the heat transfer resistance between the magnetically conductive material to be cooled and the tube wall of the cooling tube.
- the air gap between the outer wall of the cooling tube and the inner wall of the receiving area is significantly reduced or completely avoided.
- there is surface contact If - as in the prior art - the cooling tube is relatively loose in the receiving area, its circumference is practically all around surrounded by an air gap which forms a strong barrier to heat conduction.
- the surface contact according to the invention provides a significantly better coupling with regard to heat conduction. This means that the cooling capacity or the cooling efficiency is already significantly increased. Due to the seat of the cooling pipe, which is precisely defined by the groove geometry, e.g. a higher copper fill factor can be achieved by using cables with a larger cable cross-section.
- the cooling flow or the cooling tubes can also be dimensioned smaller, although a uniform and, above all, sufficient cooling can be ensured.
- the resulting cooling can also be calculated / predicted much more precisely and easily with the invention. According to the above, there is always an uncertainty in the design in the prior art.
- the invention also relates to a method for producing a primary part or secondary part according to one of claims 1 to 12.
- This method also achieves the object set above and offers a simple and effective production method for such a device. It can be provided that the cooling tube laterally, i.e. is inserted into the receiving area in the longitudinal direction of the slot. This has the advantages of lateral insertion.
- FIG. 2 shows an enlarged detail from FIG. 1,
- Figure 6 is a schematic cross-sectional drawing through a single form stamp. '
- FIG. 2 shows the configuration of slot 4, winding 5 and cooling tube 6 in detail:
- the total height h tot is composed essentially of the height of the receiving area 12 plus the remaining portion of the slot depth for the windings
- the cooling tubes 6 can pass through the holding constriction 10, 11 in the groove depth direction 16 and, as it were, engage in their receiving area 12 when a sufficient press-in force / press-in force is exerted with the die 27.
- FIG. 6 shows a single stamp 28 which is able to press individual cooling tubes 6 or sections of cooling tubes 6 individually into a groove 4 provided for this purpose.
- a single immersion rib 37 is provided, which can be immersed in succession in a respective groove 4 in order to press in the cooling tube 6.
- a plurality of individual punches 28 can also be provided, which simultaneously equip different grooves 4 with the cooling tube 6.
