Abstract
A heat exchanger core tube having a body with at least one internal fluid passage and having at least one end adapted such that an effective height results that is less than or equal to the inside diameter of a manifold and can allow the body of the core tube to have a height greater than the inside diameter of the manifold. The at least one adapted end may comprise an adapter and may be twisted such that the longitudinal axis of a core tube remains substantially normal to the longitudinal axis of the manifold and wherein the end of the core tube is angled less than 90 degrees with respect to the tube body.
Claims14
A core tube for a heat exchanger, comprising:
- a body having a maximum outside dimension;
- at least one fluid passage through the body;
- a first end portion;
- and
- a transition between the body and the end such that the end has a reduced dimension in the plane of the maximum outside dimension of the body.
A heat exchanger, comprising:
- at least one manifold;
- and
- at least one core tube having a body with at least one internal fluid passage and at least one twisted end, wherein the at least one twisted end is coupled to a manifold such that the longitudinal axis of the core tube remains substantially normal to the longitudinal axis of the manifold and wherein the end of the core tube is angled less than 90 degrees with respect to the tube body.
A method of increasing the heat transfer capability of a heat exchanger, comprising:
- providing at least one manifold;
- providing at least one core tube having a first end, a second end, and a body with at least one internal fluid passage;
- twisting at least one end of at least one core tube;
- and
- coupling the at least one twisted end to a manifold such that the longitudinal axis of the core tube remains substantially normal to the longitudinal axis of the manifold and wherein the end of the core tube is angled less than 90 degrees with respect to the tube body.
A method of increasing the heat transfer capability of a heat exchanger, comprising:
- providing at least one manifold;
- providing at least one core tube having a first end, a second end, and a body with at least one internal fluid passage;
- reducing the effective height of at least one end of at least one core tube;
- and
- coupling the reduced end to a manifold.
