Abstract
This invention claims a heat exchange system applied to the rotating electrical machine casing using the same, wherein said machines are equipped with a finned casing comprising a number of fins (2) equipped with a modified profile, each one interleaved with complementary fins (3), both profiles distributed over the external surface of the casing (1). Said fins (2) and (3) with predominantly continuous profile, supported in parallel along the casing height (1), respectively show projections (5a) and (5b) from the guideline (4), with the structures (5a) and (5b) with trapezoidal or rectangular section being interleaved to one another in the front region of the machine (1).
Claims9
A rotating electrical machine casing, comprising
- a) a number of fins equipped with a modified profile, each of them interleaved with complementary fins, both profiles distributed over side parts, upper and bottom part of an external surface of the casing;
- b) said fins having a predominantly continuous profile, supported in parallel along the casing height, respectively showing structures projecting from a guideline;
- c) the structures with trapezoidal or rectangular section interleaved to one another in a front region of the machine (1).
A heat exchange system, comprising:
- a) a rotating electrical machine equipped with a casing comprising a number of fins with a modified profile, each of them interleaved with complementary fins, both profiles distributed over an external surface of the casing;
- b) said fin and complementary fins with predominantly continuous profile, supported in parallel along a casing height, respectively showing projections (5a) and (5b) from the guideline (4);
- c) structures projecting from a guideline with trapezoidal or rectangular section interleaved to one another in a front region of the rotating electrical machine delimiting a front portion with heat dissipation.
