Devices for gas cooling plasma arc torches and related systems and methods
First Claim
1. A nozzle for a gas-cooled plasma arc torch, the nozzle comprising:
- a nozzle body having a proximal end and a distal end that define a nozzle body length and a longitudinal axis, the body including;
an exit orifice defined by the distal end of the nozzle body;
a plenum within the nozzle body, the plenum extending from the proximal end of the nozzle body to a plenum floor, a distance from the plenum floor to the distal end defining a plenum floor thickness, and a distance from the plenum floor to the proximal end of the nozzle body defining a proximal end height; and
a bore extending from the plenum floor to the exit orifice, the bore having a bore length and a bore width,wherein the nozzle body has a nozzle width in a direction transverse to the longitudinal axis, wherein the nozzle body length is greater than the nozzle width, and wherein a ratio of the proximal end height to the plenum floor thickness is less than 2.0.

Abstract
In some aspects, nozzles for plasma torches can include a nozzle body having a proximal end and a distal end that define a nozzle body length and a longitudinal axis. The body can include an exit orifice defined by the distal end; a plenum extending from the proximal end to a plenum floor, a distance from the plenum floor to the distal end defining a plenum floor thickness, and a distance from the plenum floor to the proximal end defining a proximal end height; and a bore extending from the plenum floor to the exit orifice that has a bore length and a bore width. The nozzle body has a nozzle width in a direction transverse to the longitudinal axis. The nozzle body length is greater than the width and a ratio of the proximal end height to the plenum floor thickness is less than 2.0.

16. A nozzle for an air-cooled plasma arc torch configured to operate above 100 amps, the nozzle comprising:
-
a nozzle body having a distal portion defining a conduit substantially aligned with a longitudinal axis of the nozzle body, the conduit having a conduit length and shaped to direct a plasma gas flow; and a proximal portion coupled to the distal portion and having a proximal portion length, the proximal portion defining a plenum fluidly connected to the conduit, wherein a ratio of a length of the proximal portion to the conduit length is less than about 2.0, and wherein the nozzle is configured to permit operation at a current to nozzle body length ratio of greater than about 170 amps/inch. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
