Abstract
A heat exchanger having a housing for retaining a coil bundle, wherein the housing includes a first and second movable end for contacting one housing end with one end of the coil bundle and the remaining housing end with the second end of the coil bundle. The housing includes a sliding seal between the movable ends to permit relative motion between the ends while maintaining a sealed relation therebetween. Each movable end includes an aperture and a corresponding fastener for engaging the adjacent portion of the coil bundle to draw the coiled bundle against the respective end, thereby permitting removal of one end of the housing upon removal of a single fastener.

A heat exchanger housing for retaining a coil assembly, the coil assembly having a coil bundle partially defined by a top coil and a bottom coil, and a first manifold and a second manifold fluidly connected to the coil bundle, the housing comprising:
- (a) an end wall having an end aperture therein, the end aperture sized to receive a portion of the first manifold therethrough;
- (b) a side wall connected to the end wall, the side wall including a sealing surface;
- (c) a base plate having a base aperture therein, the base aperture sized to receive a portion of the second manifold therethrough, the end wall, side wall and base plate sized so that a portion of the first manifold extends through the end aperture and a portion of the second manifold extends through the base aperture, the base plate further including a seal surface for cooperating with the sealing surface to form a sliding seal therebetween, the sliding seal configured to permit movement of the base plate in a direction towards and a direction away from the end wall in a sealed relation;
- (d) a first fastener for cooperatively engaging the first manifold to secure the coil bundle relative to the end wall and substantially preclude fluid flow between the bottom coil and the end wall;
- and
- (e) a second fastener for cooperatively engaging the second manifold to secure the coil bundle relative to the base plate;
- the side wall, base plate and end wall sized to allow movement of the base plate towards and away from the end wall to contact the bottom coil with the base plate and the top coil with the end wall, the contact of the bottom coil with the base plate and the top coil with the end wall terminates movement of the base plate towards the end wall substantially independent of contact between the base plate and side wall.
A heat exchanger assembly for retaining a coil assembly, the coil assembly having a coil bundle partially defined by an upper surface and a spaced apart lower surface, the heat exchanger assembly, comprising:
- (a) a housing for enclosing the coil bundle, the housing having first and second relatively movable ends, one of the first and the second ends including a first aperture therethrough, and a sliding seal between the first and second ends, the sliding seal sized to accommodate movement of the relatively movable ends in a direction towards each other in a sealed relation independent of motion limiting contact between the first and the second relatively movable ends, a sufficient distance to contact the first relatively movable end with the lower surface and the second relatively movable end with the upper surface and substantially preclude fluid flow between the first relatively movable end and the lower surface, and the second relatively movable end and the upper surface;
- and
- (b) a first arm attached to the coil bundle and projecting from one of the upper and the lower surface, the first arm sized to pass through the first aperture.
A heat exchanger, comprising:
- (a) a coil bundle having upper and lower surfaces;
- and
- (b) a housing enclosing the coil bundle, the housing having first and second relatively movable ends;
- and
- (c) a sliding seal between the first and second ends to permit the ends to be moved together in a sealed relation to engage the upper and lower surfaces of the coil bundle;
- the housing, the sliding seal and the coil bundle sized to contact the first movable end with the lower surface and the second movable end with the upper surface to terminate motion of the first and the second end in a direction towards each other, substantially independent of contact between the first and the second relatively movable ends along the direction.
A heat exchanger housing for retaining a coil bundle, comprising:
- (a) an adjustable housing sized to enclose the coil bundle, the adjustable housing having first and second ends moveable in a direction towards and away from each other;
- and
- (b) a sliding seal forming a sealed interface between the first and the second ends;
- the sliding seal, the first end and the second end sized to selectively vary the distance between the first end and the second end to contact the first end with a lower surface of the coil bundle to substantially preclude fluid flow therebetween and contact the second end with an upper surface of the coil bundle to substantially preclude fluid flow therebetween, the contact of the first and the second ends with the coil bundle terminating movement of the first and second ends towards each other, substantially independent of contact between the first and the second end.
