An air intake separator system includes a plurality of vanes adapted to remove fluid or precipitation from an air stream, wherein the vanes are operably coupled to tubular rods with an interference fit. Applying an elevated temperature heat transfer fluid to the plurality of vanes removes fluid or precipitation from an air stream in order to prevent ice formation. Likewise, applying a lower temperature heat transfer fluid can cool the vanes.

An evaporator includes a refrigerant conduit; and front and rear plates sandwiching the refrigerant conduit, each of the front and rear plates including: a plurality of ice forming columns; a set of first protrusions and a set of second protrusions defined therein, each first protrusion on the front plate and a corresponding first protrusion on the rear plate defining a respective active cavity and each second protrusion on the front plate and a corresponding second protrusion on the rear plate defining a respective passive cavity, the refrigerant conduit extending through each of the active cavities but not any of the passive cavities; and inner flat portions of the front plate and the rear plate facing each other to define respective spaced portions, wherein the active cavities and passive cavities are interspersed and separated by respective inner flat portions so as to define a plurality of ice forming sites.

A method of manufacturing an evaporator includes: forming a length of tubing into a serpentine path, the length of tubing forming a tubing coil; forming a first evaporator plate; forming a second evaporator plate; positioning the tubing coil between the first evaporator plate and the second evaporator plate; bringing the first evaporator plate, the second evaporator plate, and the tubing coil into contact with each other; and forming a plurality of dimples in each of the first evaporator plate and the second evaporator plate, thereby at least partially crushing the tubing coil at a position of each of the plurality of dimples, a surface of each of the dimples contacting the tubing coil.

An air intake separator system includes a plurality of vanes adapted to remove fluid or precipitation from an air stream, wherein the vanes are operably coupled to tubular rods with an interference fit. Applying an elevated temperature heat transfer fluid to the plurality of vanes removes fluid or precipitation from an air stream in order to prevent ice formation. Likewise, applying a lower temperature heat transfer fluid can cool the vanes.

The present application provides an evaporator. The evaporator may include a housing, a coil assembly mounted within the housing, and a replaceable fan module positioned within the housing. The replaceable fan module may include a fan mounted therein.

An evaporator includes a refrigerant conduit sandwiched between front and rear plates. The front plate has inner flat portions, each of which is spaced from a respective inner flat portion of the rear plate to define a respective spaced portion. The front and rear plates further include a set of first protrusions and a set of second protrusions. Each first protrusion on the front plate faces a respective first protrusion on the rear plate to define a respective active cavity. Each second protrusion on the front plate faces a respective second protrusion on the rear plate to define a respective passive cavity. The refrigerant conduit extends through each of the active cavities but does not extend through any of the passive cavities. The location of the active and passive cavities are interspersed and separated by respective inner flat portions so as to define a plurality of ice forming sites.

An evaporator plate made of a metal plate having a plurality of shaped dimples thereon, the dimples each being defined by a pair of opposing pyramid shaped end faces and a pair of trapezoidal shaped left and right side faces adjoining the pair of pyramid shaped end faces. An evaporator assembly comprising first and second evaporator plates and tubing arranged in a serpentine path sandwiched therebetween, each plate including a plurality of parallel fins extending from a first surface, a pair of end flanges parallel to the fins, and a plurality of the shaped dimples. A tool for making the plate and a method of making the assembly are disclosed.

The present application provides an evaporator. The evaporator may include a housing, a coil assembly mounted within the housing, and a replaceable fan module positioned within the housing. The replaceable fan module may include a fan mounted therein.

A device that helps to properly align and install large pistons in cylinders is disclosed. Large pistons and cylinders are heavy and difficult to handle, and if the piston is not inserted in the cylinder perfectly in line with the length of the cylinder, damage results. The device holds both the piston and cylinder being assembled, and has a number of alignment mechanisms. A laser is also used to set up the device and to ensure that the piston is straight with the center line of the cylinder for proper alignment and insertion.

An air humidifier for generating humidified breathing air for a patient includes a boiling pot for receiving a defined water volume. The air humidifier has a partition, the partition having at least one perforation. The partition with perforation is designed to be arranged above a water surface of the defined water volume in the boiling pot.
