Abstract: A combo-cooler includes heat exchangers having parallel tubes corresponding to each heat exchanger aligned in a tube plane. A first end tank assembly includes a columnar end tank separated by a baffle into compartments each in fluid communication with a respective hydraulically independent fluid circuit. The second tank assembly includes manifolds aligned in a column. Serially adjacent manifolds are in slidable contact or separated by a respective gap to allow relative translation. Banks of the tubes are brazed in fluid communication with a compartment and a manifold to connect the compartment and the manifold to have a respective fluid flow therethrough. A bracket contacts at least two of the serially adjacent manifolds to prevent translation between the bracket and the serially adjacent manifolds perpendicular to the tube plane and to allow relative translation between the at least two of the serially adjacent manifolds parallel to the tubes.

Abstract: Heat exchanger tubes are disclosed herein. An embodiment of a heat exchanger tube includes a tube body having two opposed sides. A plurality of exterior flow passages is defined in the tube body adjacent one of the two opposed sides. A plurality of interior flow passages is defined in the tube body adjacent the plurality of exterior flow passages. The plurality of exterior flow passages has at least one of an average hydraulic diameter or an average width that is i) greater than at least one of an average hydraulic diameter or an average width of the interior flow passages and ii) less than twice the at least one of the average hydraulic diameter or the average width of the interior flow passages.

Abstract: A cooling module for a vehicle includes a combo cooler associated with a vehicle. A heat rejecter includes tubes arranged in a planar configuration. A low temperature radiator is associated with the heat rejecter and includes low temperature radiator tubes arranged in a planar configuration. Manifolds are independently configured to supply a refrigerant to the heat rejecter and a coolant to the low temperature radiator. A high temperature radiator is disposed adjacent and parallel to the combo cooler, and downstream of the combo cooler relative to an air stream flowing through the combo cooler and the high temperature radiator. The high temperature radiator is associated with a high temperature cooling loop of the vehicle, and cools an other coolant flowing therethrough. An operating temperature of refrigerant in the heat rejecter and an operating temperature of coolant in the low temperature radiator are lower than an operating temperature of the other coolant in the high temperature radiator.
