ELECTRIC HEATER FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an electric heater for a vehicle capable of efficiently radiating heat in a circuit without providing a new heat radiating mechanism. SOLUTION: This electric heater S for the vehicle is constituted of a heating body 1 and an energizing control part 2 for controlling energizing of the heating body 1 according to a control signal from a central control part 7. The energizing control part 2 is provided on a circuit board 4 of a brushless DC motor device 101 for a vehicle together with an energizing circuit part 3 of the brushless DC motor device 101. The heater is made to efficiently radiate heat, being different from a conventional heater provided with the energizing control part 2 closely to the heating body 1.
