Provided is a vehicle heat exchange apparatus having a structure that allows a gap between a radiator and another heat exchanger disposed side by side therein to be closed in a simple and stable manner even it the radiator and the heat exchanger are largely spaced from each other. A vehicle heat exchange apparatus according to an embodiment of the present invention includes a radiator, a heat exchanger, air barrier walls, and closure members. The radiator has a core and tanks provided on left and right sides of the core. The heat exchanger is disposed side by side with the radiator in a front-back direction of a vehicle. The air barrier walls are provided on the respective tanks and extend toward the heat exchanger while leaving a gap between the air barrier walls and the heat exchanger. The closure members each close at least a portion of the gap.

A radiator assembly in which numerous fins of a cooling element extending between two coolant channels of the cooling element are divided into at least two different cooling zone, a ventilator of the radiator assembly at least partially covers a first cooling zone of the at least two different cooling zones with respect to a direction extending from the ventilator module toward the cooling element, and a gap width of a gap between two adjacent fins in the first cooling zone is greater than that in a second cooling zone of the at least two different cooling zones.

Apparatuses and methods are disclosed including heat exchanger for an internal combustion engine. The heat exchanger can include a main body, a manifold and one or more outlet ports. The main body can have an inlet and an outlet to receive/pass a coolant on a first side thereof. The main body can have a fluid inlet and fluid outlet configured to receive a fluid. The main body can pass the fluid in a heat exchange relationship with the coolant. The manifold can be coupled to the main body on a second side. The manifold can be in fluid communication with a main coolant outlet passage to receive a portion of the coolant from the main body. The one or more outlet ports can be fluidly connected to the manifold and passing the portion of the coolant to one or more engine auxiliary systems.

A second temperature adjustment medium branches and flows into the first branch flow path and the second branch flow path at the branching portion, the second temperature adjustment medium and the second temperature adjustment medium are merged at the merging portion and flow through the pressure feed flow path to be supplied to the first pump, and the second temperature adjustment medium circulates through the second temperature adjustment circuit. A valve device configured to adjust a flow rate of the second temperature adjustment medium flowing through the second branch flow path is provided in the second branch flow path between the branching portion and the heat exchanger. The control device is configured to control the valve device to block the second temperature adjustment medium from flowing through the second branch flow path when a failure of the heat exchanger is detected.
