Abstract:
1. A cogeneration apparatus comprising: a housing having an interior space partitioned into a power-generation compartment and an electrical-equipment compartment communicating with atmosphere through an outside-air-introducing part; a motor accommodated in the power-generation compartment; an electrical generator accommodated in the power-generation compartment and adapted to be driven by the motor; a ventilation fan, accommodated in the power-generation compartment, for leading a cooling air flow to the electrical generator; a heat exchanger, accommodated in the power-generation compartment, for generating hot water using waste heat of the motor as a heat source; a control part, accommodated in the electrical-equipment compartment, for controlling the motor; and a power converter part, accommodated in the electrical-equipment compartment, for converting alternating-current power produced by the electrical generator into electrical power of a desired format, wherein the cogeneration apparatus further comprises a ventilation-introducing channel placing the electrical-equipment compartment in communication with the ventilation fan, so that driving the ventilation fan causes air to be led from outside the housing through the electrical-equipment compartment to inside the ventilation-introducing channel, the air led to inside the ventilation-introducing channel is led to the electrical generator, and the air led to the electrical generator is exhausted through the power-generation compartment to outside the housing.
