Title:
INVERTER-INTEGRATED ELECTRIC COMPRESSOR AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2024/057922
Kind Code:
A1
Abstract:
[Problem] To provide an inverter-integrated electric compressor with which, while reducing the weight of a cover that closes an inverter accommodating portion, and reducing production costs, it is also possible to suppress vibration and noise resulting from resonance. [Solution] This inverter-integrated electric compressor is provided with a cover 15 for closing an inverter accommodating portion 13. The cover 15 is made from sheet metal comprising: a shell-shaped upper wall portion 41; a longitudinal wall portion 42 formed continuously with an outer periphery of the upper wall portion; and a seal flange portion 46 which projects outward continuously from an outer periphery of the longitudinal wall portion, and which is attached to a housing 11. By adjusting a radius of curvature of an arch forming the shell shape of the upper wall portion and adjusting an angle at which the longitudinal wall portion rises from the seal flange portion, a natural frequency of the cover can be shifted from a resonance point with an excitation force of a compressing mechanism 4 and an electric motor 2.
