Abstract
The invention is directed to a nozzle for a hot air device used in the electronic assembly industry to melt solder or heat shrink-wrap insulators. The nozzle provides a uniform temperature environment and suppresses the occurrence of local excess heating.
Claims11
A hot air nozzle for use with a hot air blowing device or system, the hot air nozzle comprising:
- a convection box secured to a connection cylinder extending from a baffle plate and an insertion cylinder removeably secured to said hot air blowing device;
- wherein said convection box includes an end wall and side walls defining a convection space, said end wall having at least one air inlet orifice and spaced apart exhaust ports whereby hot air exhausting from said convection space impinges upon said baffle plate positioned opposing said end wall and spaced apart by a length of said connection cylinder.
A hot air nozzle for use with a hot air blowing device or system, the hot air nozzle comprising:
- a convection box secured to a connection cylinder extending from a baffle plate and an insertion cylinder removeably secured to said hot air blowing device;
- wherein said convection box includes an end wall and side walls defining a convection space, said end wall having at least one air inlet orifice and spaced apart exhaust ports whereby hot air exhausting from said convection space impinges upon said baffle plate positioned opposing said end wall and spaced apart by a length of said connection cylinder;
- wherein said connection cylinder further comprises an outer cylinder made from the same piece as said end wall of the convection box and an inner cylinder is made from the same piece as the baffle plate.
A hot air nozzle for use with a hot air blowing device or system, the hot air nozzle comprising:
- a convection box having an end wall having a hot air inlet and side walls extending from said end wall;
- a connection cylinder;
- a baffle plate;
- and
- an insertion cylinder, said insertion cylinder attached at its distal end to said baffle plate, said insertion cylinder configured to be attached securely to said hot air blowing device;
- wherein said connection cylinder extends between said baffle plate and said convection box whereby exhaust ports formed in said end wall of said convection box are oppositely disposed to said baffle plate whereby hot air exhausting from said convection box impinges upon said baffle plate.
