Abstract
A fluid temperature stabilization system may employ an exterior casing defining an internal cavity, one or more phase change material may be located within the internal cavity. A fluid inlet may be located at a first end of the casing providing access into the internal cavity, and an outlet may be located at a second end of the casing providing fluid access from the internal cavity.
Claims19
A fluid temperature stabilization system comprising:
- an exterior casing having a first end wall, a second end wall, a first side wall, and a second side wall that define an internal cavity that extends along a longitudinal axis of the exterior casing from the first end wall to the second end wall;
- a plurality of internal casings disposed within the internal cavity, each internal casing having an upstream wall, a downstream wall, a third end wall, and a fourth end wall, the third end wall being proximate to the first side wall, the fourth end wall being proximate to the second side wall, the upstream and downstream walls extending between the third and fourth end walls transverse to the longitudinal axis of the exterior casing;
- a first phase change material located within a first one of the internal casings;
- a second phase change material located within a second one of the internal casings;
- an inlet located at the first end wall of the exterior casing providing entry of a fluid into the internal cavity;
- and
- an outlet located at the second end wall of the exterior casing providing exit of the fluid from the internal cavity;
- wherein:
- the first and second internal casings are staggered along the longitudinal axis such that the fluid flows in a flow path that proceeds from between the third end wall of the first internal casing and the first side wall, to between the downstream wall of the first internal casing and the upstream wall of the second internal casing, and then between the fourth end wall of the second internal casing and the second side wall;
- and
- the plurality of internal casings are arranged to promote contact of the fluid on all sides of the plurality of internal casings when the fluid flows between the inlet and the outlet.

- a vehicle exhaust pipe;
- a vehicle fresh air intake pipe;
- and
- a cross pipe permitting fluid communication between the vehicle exhaust pipe and the vehicle fresh air intake pipe, the cross pipe further comprising:
- an exterior casing having a first end wall, a second end wall, a first side wall, and a second side wall that define an internal cavity that extends along a longitudinal axis of the exterior casing from the first end wall to the second end wall;
- a first internal casing and a second internal casing, the first and second internal casings being disposed within the internal cavity, the first internal casing having a first upstream wall, a first downstream wall, a third end wall, and a fourth end wall, the third end wall being proximate to the first side wall, the fourth end wall being proximate to the second side wall, the first upstream wall and the first downstream wall extending between the third and fourth end walls transverse to the longitudinal axis of the exterior casing, the second internal casing having a second upstream wall, a second downstream wall, a fifth end wall, and a sixth end wall, the fifth end wall being proximate to the first side wall, the sixth end wall being proximate to the second side wall, the second upstream wall and the second downstream wall extending between the fifth and sixth end walls transverse to the longitudinal axis of the exterior casing;
- at least one piece of a first phase change material located within the first internal casing;
- at least one piece of a second phase change material located within the second internal casing;
- an inlet located at the first end wall of the exterior casing providing entry of a fluid into the internal cavity;
- and
- an outlet located at the second end wall of the exterior casing providing exit of the fluid from the internal cavity;
- wherein:
- the first internal casing is disposed between the second internal casing and the first end wall;
- first and second internal casings are staggered such that the third end wall is spaced apart from the first side wall a greater distance than the fifth end wall, and the sixth end wall is spaced apart from the second side wall a greater distance than the fourth end wall;
- the third end wall is a greater distance from the first side wall than the fourth end wall is from the second side wall, and the sixth end wall is a greater distance from the second side wall than the fifth end wall is from the first side wall;
- the first and second internal casings are arranged within the internal cavity such that the fluid has a flow path that flows between the third end wall and the first side wall, between the first downstream wall and the second upstream wall, and then between the sixth end wall and the second side wall;
- and
- the first and second internal casings are arranged to promote contact of the fluid on all sides of the first and second internal casings when the fluid flows between the inlet and the outlet.
