The evaporator (10) contains a top plate (20) and a bottom plate (30). The top plate (20) is mated to the bottom plate (30) to define a main chamber (130) for distribution of gas. An input port (80) is defined within the bottom plate (30) of the evaporator (10) is in fluid communication with a gas distribution channel (100). The gas distribution channel (100) has a series of gas distribution ports (110A-C) increasing in diameter, in proportion to a distance from the input port (80), that provide for an even distribution of gas into the main chamber (130). Gas exits the main chamber (130) through exit ports (120A-C) defined within the bottom plate (30). Screws (50) respectively control gas flow to exit ports (120A-C) for delivery to an array of nozzles (90) on the bottom plate (30). ## Claims ### Claim 1 An evaporator, comprising: a main body defining an input port for receipt of an inflow gas, a gas distribution channel in fluid communication with the input port; the main body further defining a main chamber in fluid communication with the gas distribution channel via a plurality of gas distribution ports, each gas distribution port having a defined aperture to direct the flow of inflow gas in a first direction towards a top portion of the main body, the plurality of gas distribution ports having increasing diameter, in proportion to a distance from the input port, to provide for an even distribution of gas into the main chamber; at least one exit port defined within the main body and in fluid communication with the main chamber to direct the flow of outflow gas in a second direction opposite of the inflow fluid and through a bottom portion of the main body to allow for equal flow rates in at least one nozzle, the least one nozzle connected adjacent to the main body in respective fluid communication with the at least one exit port, whereby the inflow gas is introduced into the evaporator through the input port and into the gas distribution channel, the inflow gas travels through the input port and into the main chamber to provide an even distribution of gas into the main chamber, thereafter the outflow gas exits the main chamber through the exit port. ### Claim 2 (depends on 1) The evaporator of claim 1, wherein the at least one nozzle is needle connected to the main body with a Leur lock. ### Claim 3 (depends on 1) The evaporator of claim 1, further comprising: means for controlling gas flow through the at least one exit port. ### Claim 4 (depends on 3) The evaporator of claim 3, wherein the means for controlling gas flow is at least one screw in adjustable threadable engagement with the main body having a tip that respectively resides proximal to the at least one exit port. ### Claim 5 (depends on 1) The evaporator of claim 1, wherein the at least one exit port is a 4×6 array of 24 exit ports. ### Claim 6 (depends on 1) The evaporator of claim 1, wherein the main body includes a first plate and a second plate matable together. ### Claim 7 (depends on 6) The evaporator of claim 6, further comprising: a gasket residing between the first plate and the second plate. ### Claim 8 (depends on 1) The evaporator of claim 1, wherein the at least one gas distribution port is three gas distribution ports. ### Claim 9 An evaporator, comprising: a top plate; and a bottom plate having an input port for receipt of an inflow gas in fluid communication with a gas distribution chamber that terminates in a plurality of gas distribution ports, each gas distribution port having a defined aperture to direct the flow of inflow gas in a first direction towards the top plate; the top plate and the bottom plate being matable together to provide a main chamber there between; the plurality of gas distribution ports being in fluid communication with the main chamber, a diameter of the plurality of gas distribution ports increasing in size the further away from the input port; the bottom plate further including an array of exit ports for distribution of outflow gas in a second direction opposite of the inflow fluid and through the bottom plate to allow for equal flow rates in a plurality of nozzles, the plurality of nozzles connected adjacent to an outer surface of the bottom plate and in respective fluid communication with the exit ports. ### Claim 10 (depends on 9) The evaporator of claim 9, wherein the plurality of nozzles is needles connected to the bottom plate by a Leur lock. ### Claim 11 (depends on 9) The evaporator of claim 9, further comprising: means for controlling gas flow through the plurality of exit ports. ### Claim 12 (depends on 11) The evaporator of claim 11, wherein the means for controlling gas flow through the plurality of exit ports includes an array of female threaded bores in the top plate with screws, each having a tip, adjustably threadably received therein and in registration with the plurality of exit ports for independent respective control of gas flow through each exit port. ### Claim 13 (depends on 12) The evaporator of claim 12, wherein each tip of the screws complementarily mate with their respective exit port. ### Claim 14 (depends on 9) The evaporator of claim 9, further comprising: a gasket disposed between the first plate and the second plate thereby preventing leakage of pressurized gas. ### Claim 15 An evaporator, comprising: a top plate having an inner and outer surface; a bottom plate having an inner and outer surface, the inner surface of the bottom plate mated to the inner surface of the top plate to define a main chamber therein used for distribution of gas, the inner surface of the bottom plate defining exit ports for the exit of gas from the main chamber, the exit ports defined within the bottom plate and in fluid communication with the main chamber to direct the flow of outflow gas in a second direction opposite of an inflow fluid to allow for equal flow rates in a plurality of nozzles, the plurality of nozzles connected adjacent to an outer surface of the bottom plate and in respective fluid communication with the exit ports; an input port for delivery of gas contained within bottom plate and in fluid communication with a gas distribution channel defined within the bottom plate, each gas distribution port having a defined aperture to direct the flow of inflow gas in a first direction towards the top plate, the gas distribution channel having at least one gas distribution port of increasing diameter, in proportion to a distance from the input port, to provide for an even distribution of gas into the main chamber; and whereby the inflow gas is introduced into the evaporator through the input port and into the gas distribution channel, the inflow gas travels through the input port and into the main chamber to provide an even distribution of gas into the main chamber, thereafter the outflow gas exits the main chamber through the port.
