Embodiment Construction

[0054] Embodiments of the present invention will be described below with reference to the drawings.

[0055] figure 1 It is a perspective view showing the appearance of the power generating device of the present invention. figure 2 It is a sectional view of the power generating device.

[0056] Such as figure 1 As shown, the power generating device 1 is equipped with a substantially rectangular parallelepiped casing 10, as figure 2 As shown, an engine 11 is housed below the inside of the casing 10 .

[0057] The engine 11 includes a cylinder, a combustion chamber, and a crankcase (none of which are shown), a piston (not shown) is reciprocally housed in the cylinder, and a crankshaft 12 is rotatably housed in the crankcase. The piston and the crankshaft 12 are connected to each other by an unillustrated connecting rod. Furthermore, the crankshaft 12 is configured to be rotatable by driving the engine 11 , and one end of the crankshaft 12 protrudes from the side of the en...

Abstract

The present invention provides a power generation device, capable of efficiently performing heat radiation on a coil portion. The power generation device is provided with a rotor (40), a stator (30),a coil (33), a base member (34) and a radiator (36), wherein the rotor (40) is rotatably driven by a crankshaft (12) of an engine (11), and the rotor (40) is formed through arrangement of a permanentmagnet (43) on an inner circumferential surface of a rotor yoke (42); the stator (30) is formed through stacking of a plurality of electromagnetic steel sheets; the coil (33) is formed by winded wireson a plurality of stator cores (31) opposed to the permanent magnets (43) of the rotor (40); the base member (34) is disposed on the inner circumference of the stator (30); the radiator (36) is arranged at a substantially central portion in the thickness direction of the stator cores (31) in a manner of being clamped by the electromagnetic steel sheets; and the base member (34) and the radiator (36) are made of materials having a higher thermal conductivity than the electromagnetic steel sheets of the stator (30).

Description

technical field [0001] The present invention relates to a power generating device, and in particular, to a power generating device capable of heat dissipation of a stator. Background technique [0002] Conventionally, a power generator is known that generates power by utilizing the rotation of a crankshaft of an engine. [0003] For such a power generation device, for example, a technology has been disclosed in which a plurality of thin plate sheets overlapped and arranged in a planar shape and at least one heat conduction layer arranged on the thin plate sheets in a planar shape are provided, and the heat conduction layer is formed as a The thermal conductivity is higher than that of the thin plate (for example, refer to Patent Document 1). [0004] In addition, as other technologies, for example, the following technology has been disclosed in the past: the stator of the magnet has a plurality of metal plates superimposed in surface contact with each other, and coils wound...
