Embodiment Construction

[0064] The illustrations in the figures are in schematic form. It is to be noted that similar or identical elements are denoted by the same reference numerals in different figures.

[0065] figure 1 A cooling support element 100 is illustrated according to one embodiment. The cooling support element 100 can be used for a stator segment of a stator of an electrical machine, in particular a stator segment of a generator.

[0066] The cooling support element 100 comprises a first plate 101 . The first plate 101 has an upper surface and a lower surface, wherein the upper surface of the first plate includes anchoring means (not shown) for anchoring a stator lamination stack (not shown), which can be attached to a cooling Support element 100 . The cooling support element can serve as a support structure for the stator lamination stack and at the same time as a cooling device for the stator lamination stack, in particular a cooling device for the windings arranged in the stator l...

Abstract

It is described a cooling support element (100) for a stator segment for a stator of an electrical machine, in particular a generator. The cooling support element (100) comprises a first plate (101) having an upper surface and a lower surface, wherein the upper surface of the first plate comprises anchoring means for anchoring a stator lamination stack being attachable to the cooling support element (100), a second plate (102) having an upper surface and a lower surface, wherein the lower surface of the second plate comprises an inlet opening (103) and an outlet opening (104). The first plate is attached to the second plate in such a manner that the lower surface of the first plate (101) faces the upper surface of the second plate (102). Separator elements (105, 106) are disposed between the lower surface of the first plate (101) and the upper surface of the second surface (102) such that a cooling channel is provided between the first plate (101) and the second plate (102), and a cooling fluid is guidable from the inlet opening (103) through the cooling channel to the outlet opening (104) for dissipating heat from the stator lamination stack. Further, a stator segment, a stator, an electrical machine and a method for manufacturing a cooling support element are described.

Description

technical field [0001] The invention relates to a cooling support element for a stator segment of a stator of an electrical machine, in particular a generator. Further, the invention relates to a stator segment comprising such a cooling support element. Furthermore, the invention relates to a stator comprising said stator segments. Furthermore, the invention relates to an electric machine comprising said stator, for example to a generator for a wind turbine. Among other things, the invention relates to a method for producing such a cooling support element. Background technique [0002] An electric machine, such as a generator for a wind turbine, may include a rotor and a stator. The stator may consist of a set of laminations, wherein one or more coils or windings may be arranged in slots of the stator lamination set. [0003] In such electric machines, heat is generated when converting mechanical energy into electrical energy or converting electrical energy into mechanic...
