Title:
HEATING APPARATUS
Document Type and Number:
Japanese Patent JP3832020
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To achieve silencing in a heating apparatus by accomplishing the cooling of electronic components by forced convection employing a heat drive type without using a fan.
SOLUTION: In this heating apparatus, a communication air path 14 which is made to communicate with outside air and provided with a suction hole 15 downward in the direction of gravity and an exhaust hole 16 upward in the direction of gravity is provided with a cooling part 17 such as heat sink and a heat generation part 18 such as electric heater above the cooling part 17. Air near the heat generation part 18 in the communication air path 14 is heated by the heat generation part 18 to generate an ascending current and outside air is introduced from the suction hole 15 to cool the cooling part 17 and electronic components 19 such as transistor by forced convection without a fan.
