Abstract
Official abstract text for this publication.
In the power generator, an alternator driven by an engine to generate power, an inverter for the alternator, a fan to cool the engine, and a shroud via which air blown by the fan is guided to a periphery of the engine are stored inside of a casing. A fan cover that covers the alternator and the fan is provided in an end portion of the shroud, a ventilating opening is formed in an end portion of the fan cover, and an inverter supporter in which the inverter is installed is provided in a circumferential edge portion of the ventilating opening.
First claim
Opening claim text (preview).
What is claimed is: 1. A power generator in which an alternator driven by an engine to generate power, an inverter for the alternator, a fan to cool the engine, and a shroud via which air blown by the fan is guided to a periphery of the engine are stored inside of a casing, wherein a fan cover that covers the alternator and the fan is provided in an end portion of the shroud, a ventilating opening is formed in an end portion of the fan cover, and an inverter supporter in which the inverter is installed is provided in a circumferential edge portion of the ventilating opening, wherein the fan cover is made of a metal having thermal conductivity, the inverter includes a substrate and an element mounted on the substrate, the inverter supporter is made of a metal having thermal conductivity, and is provided in the circumferential edge portion of the ventilating opening, the inverter supporter includes a support plate that is provided outside the ventilating opening, and that extends in a direction orthogonal to an output shaft of the engine, and the inverter is installed such that the substrate abuts on the support plate. 2. The power generator according to claim 1 , wherein the inverter supporter is formed in an annular shape along the ventilating opening, and the inverter is installed along a circumferential direction of the inverter supporter. 3. The power generator according to claim 1 , wherein the inverter supporter is formed in a region of a part of the ventilating opening in a circumferential direction. 4. The power generator according to claim 1 , wherein a cooling fin is provided on an inner peripheral surface of the ventilating opening. 5. The power generator according to claim 1 , wherein a vibration reduction member made of an elastic material is provided between the fan cover and the shroud. 6. The power generator according to claim 5 , wherein a recoil to start the engine is attached to the fan cover. 7. The power generator according to claim 6 , wherein the recoil is disposed apart from the inverter supporter.
