Method for automatic calculation of axial cooling fan shroud circular opening size

A computer system comprising:

• one or more processors;
• memory operatively coupled to the one or more processors, and
• computer storage storing a computer program for determining shroud size of an axial fan that comprises instructions to cause the computer system to:
• receive digital data of a three-dimensional representation of a shroud and an axial fan;
• partition the received digital data into a first partition corresponding to a shroud segment and a second partition corresponding to an axial fan segment,
• determine a shroud boundary ring for the shroud segment;
• apply to an image of the first partition a series of beams to determine in pixels a shroud diameter of the shroud;
• determine pixels in the image that have values that produce a signal indicating that the pixels are coincident with portions of the shroud;
• and
• calculate the shroud diameter from information from the series of beams, including beam angles and length of travel of the series of beams when the signal is detected.

A computer program product stored on an non-transitory computer readable medium for determining shroud size of an axial fan, the computer program product including instructions for causing a system comprising one or more processors and memory to:

• receive digital data of a three-dimensional representation of a shroud and an axial fan;
• partition the received digital data into a first partition corresponding to a shroud segment and a second partition corresponding to an axial fan segment,
• determine a shroud boundary ring for the shroud segment;
• apply to an image of the first partition, a series of beams to determine in pixels a shroud diameter of the shroud;
• determine pixels in the image that have values that produce a signal indicating that the pixels are coincident with portions of the shroud;
• and
• calculate the shroud diameter from information from the series of beams, including beam angles and length of travel of the series of beams when the signal is detected.
