Charge air cooler with integrated adjustable drain mechanism

摘要

A charge air cooler comprises an outlet tank having a drain mechanism integrated in a wall thereof. The drain mechanism comprises a first valve head disposed to a first side of the wall, a first spring member disposed between the first valve head and the wall, a second valve head disposed to a second side of the wall, a second spring member disposed between the second valve head and the wall, and a valve stem coupled to each of the first valve head and the second valve head. The valve stem is reciprocatingly disposed within an aperture formed in the wall. The drain mechanism is configured to be in a closed position when an internal pressure within the outlet tank is at least one of greater than a first pressure value and lower than a second pressure value.

1. A drain mechanism disposed in a wall of an outlet tank of a charge air cooler, the drain mechanism comprising:
a first valve head disposed on a first side of the wall and within a hollow interior of the outlet tank; a second valve head disposed on a second side of the wall and an exterior of the outlet tank; and a valve stem having a first end coupled to the first valve head and a second end coupled to the second valve head, wherein the valve stem is reciprocatingly disposed within an aperture formed in the wall of the outlet tank, the aperture providing selective fluid communication between the hollow interior of the outlet tank and the exterior of the outlet tank, wherein the valve stem is surrounded by an electromagnet configured to urge the valve stem in a direction toward the hollow interior of the outlet tank when the electromagnet is electrically energized, wherein the valve stem has a hollow interior including an inlet formed in the first end thereof providing fluid communication between the hollow interior of the outlet tank and the hollow interior of the valve stem and a drain aperture formed in a sidewall of the valve stem, the drain aperture selectively providing fluid communication between the hollow interior of the valve stem and the exterior of the outlet tank.
