Bearing chamber with mapped thermal heat exchange fins

A method of additively manufacturing a bearing chamber, the method comprising:

• generating a three-dimensional (3D) model of the bearing chamber;
• generating a heat map of the 3D model which is illustrative of first thermal effects the bearing chamber is expected to experience during additive manufacturing;
• generating a heat map of the 3D model which is illustrative of second thermal effects the bearing chamber is expected to experience during operational use;
• updating the 3D model to include 3D heat exchange fin models for reducing the first and second thermal effects;
• updating the 3D model with the 3D heat exchange fin models to include 3D weight reduction cavity models for weight-neutralizing the 3D heat exchange fin models;
• and
• additively manufacturing the bearing chamber according to the 3D model, the 3D heat exchange fin models and the 3D weight reduction cavity models such that the bearing chamber comprises:
• a bearing chamber body comprising a portion of the bearing chamber body defining weight reduction cavities;
• a surface extending off the bearing chamber body;
• and
• heat exchange fins integrally formed with the surface to be disposed at a distance from and to face inwardly toward the portion of the bearing chamber body.

A bearing chamber, comprising:

• a bearing chamber body comprising a portion of the bearing chamber body defining weight reduction cavities;
• a surface extending off the bearing chamber body;
• and
• heat exchange fins integrally formed with the surface to be disposed at a distance from and to face inwardly toward the portion of the bearing chamber body,
• the heat exchange fins being configured to reduce first thermal effects the bearing chamber is expected to experience during additive manufacturing thereof and to reduce second thermal effects the bearing chamber is expected to experience during operational use thereof, and
• the portion of the bearing chamber body toward which the heat exchange fins face defining the weight reduction cavities for weight-neutralizing the heat exchange fins.
