Title:
NOZZLE FOR HEATING DEVICE, HEATING DEVICE, AND NOZZLE FOR COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/036948
Kind Code:
A1
Abstract:
A nozzle for a heating device provides an improved heat exchange rate (heat transfer coefficient) without an increase in the output of a fan motor.
Gas which is heated by a heater section or gas which is cooled by a cooling section is delivered to a discharge nozzle (2) by a fan, and the discharge nozzle (2) discharges the gas, which is delivered by the fan, from the discharge opening. The shape of the discharge opening in a plan view is non-circular and has inwardly protruding protrusions. As a result, when the flow of the gas discharged from the discharge opening of the discharge nozzle (2) is cross-sectioned by a plane perpendicular to the discharge direction of the gas, the cross-section has a shape which varies with time due to the protrusions (switching phenomenon). The switching phenomenon can increase the heat exchange rate (heat transfer coefficient) relative to a printed circuit board without an increase in the output of the fan motor for rotating the fan.
