Abstract: A heat exchanger assembly includes at least first and second coils adapted to contain a fluid therein and at least two support members securing the coils. Each of the first and second coils are individually formed of at least one tube including an inlet at an uppermost extent thereof and an outlet at a lowermost extent thereof and include a vertical column containing a plurality of horizontal rows and a plurality of bends at opposite ends of the horizontal rows and fluidically interconnecting the horizontal rows thereof in series to define a serpentine configuration. The first and second coils are adjacent each other and nested so that the horizontal rows of the first coil are parallel to the horizontal rows of the second coil and at least some of the horizontal rows of the first coil are disposed between adjacent pairs of the horizontal rows of the second coil.

Abstract: An atomizing spray head suitable for delivering an atomized spray of a fluid with reduced blockage within the spray head. The spray head includes an inlet having a passage therein, a female tapered seat fluidically coupled to the passage of the inlet, and a male tapered plunger seated against the female tapered seat. The male tapered plunger is adjustably biased against the female tapered seat to pressurize a fluid that flows into the passage and causes the male tapered plunger to be unseated from the female tapered seat. A window circumferentially surrounds the male tapered plunger, through which a pressurizing fluid that unseats the male tapered plunger from the female tapered seat is able to exit the spray head as an atomized spray in radial directions relative to the male tapered plunger.

Abstract: An heat exchanger assembly and a method of use thereof adapted for transferring heat to or from a fluid to a surrounding environment within an apparatus, such as motor vehicle engines, as it enters and leaves a fluid-handling device. The heat exchanger assembly includes first and second manifolds, multiple cooling tubes and a return tube. The first manifold has inlet holes therein and the second manifold has outlet holes therein. The multiple cooling tubes fluidically interconnect the first and second manifolds and the inlet and outlet holes thereof. The return tube passes through the first and second manifolds to fluidically interconnect opposite ends of the heat exchanger assembly. The return tube has a first end adapted to mount the heat exchanger assembly to the apparatus and an oppositely-disposed second end that protrudes from the second manifold and is adapted to secure the fluid-handling device thereto.
