The present invention relates to a heating apparatus using an air wall, which comprises: a housing with multiple hot air discharge holes on one side of the external surface and an installation space inside; an air blowing unit installed in the housing to suck air from outside and to discharge the sucked air toward the hot air discharge holes; a burner unit installed in the housing to emit flame upward; an internal pipe installed on one inner side of the housing, and having a heating space through which the flame emitted from the burner unit is provided inside and multiple penetrating holes provided on the external surface; and an air wall forming unit installed on one side of the housing and having the burner unit on one side and a space unit, which is connected to the air blowing unit, inside. The air wall forming unit has multiple air discharge holes on one side in the top surface, which is corresponding to the space in between the external surface of the housing and the external surface of the internal pipe, in the direction of the outer circumference of the internal pipe. According to the present invention, the present invention forms an air wall upward in the space in between the internal pipe and the housing to prevent the heat of the flame from being conveyed to another internal part and to cool down the electronic units in the housing. The present invention also guides the direction of the flame generation to prevent damage to other parts, to greatly extend the life, and to improve the heating efficiency. |
