A heat exchange system and apparatus for a vehicle powertrain configured to exchange heat between a first fluid and a second fluid within a heat exchanger core formed by a plurality of stacked plates having separate channels for the first fluid and the second fluid. The heat exchanger system includes multiple heat exchangers, one of which is connected to a both the inlet and the outlet of a vehicle powertrain component, another of which is fluidly connected or at least partially disconnected from the vehicle component according to the mode of operation of the heat exchange system. The heat exchanger connected to the vehicle component includes a jumper tube to return the first fluid to the vehicle component through a core of the heat exchanger.

Heat exchanger and heat exchange system

A thermal management unit for a vehicle powertrain includes an integrated oil heater, a control valve, and a pressure relief valve. A remote oil cooler is connected to fluid ports of the thermal management unit. Transmission oil is received into the thermal management unit and is directed to one or both of the transmission oil heater and the transmission oil cooler. A portion of the flow of oil can be internally bypassed through the pressure relief valve to maintain the pressure of the oil below a threshold. The flow of oil is directed through the control valve after having been heated and/or cooled, and the proportions of oil being directed through the oil heater and the oil cooler are determined by the temperature of the oil in the control valve.

A charge air cooler includes a first, second, and third heat exchange sections. In the first heat exchange section, heat is transferred from a first flow of liquid coolant to a refrigerant in order to cool the first flow of liquid coolant from a first temperature to a second temperature. In the second heat exchange section, heat is transferred from a flow of charge air to a second flow of liquid coolant in order to cool the flow of charge air from a third temperature to a fourth temperature. In the third heat exchange section, heat is transferred from the flow of charge air to the first flow of liquid coolant in order to cool the flow of charge air from the fourth temperature to a fifth temperature, the fifth temperature being less than the first temperature.

Charge air cooler and method

A cooled gear housing includes a first casing section and a second casing section joined together to define an internal volume of the gear housing assembly. A heat conducting membrane is arranged within the gear housing assembly to hydraulically separate a first portion of the internal volume from a second portion of the internal volume. Two or more meshed gears are located within the first portion of the internal volume. Coolant inlet and outlet ports are arranged on one of the casing sections, and are in fluid communication with the second portion of the internal volume.

Cooled gear housing assembly

A gear casing heat exchanger has a mounting flange separating the heat exchanger into a first side and a second side. A manifold section is on the first side, and includes an inlet manifold and an outlet manifold. A heat exchange section is on the second side, and extends from the mounting flange in a lengthwise direction. A sealing perimeter is on the second side, and the heat exchange section is entirely contained within a projection of the sealing perimeter in the lengthwise direction. The heat exchange section of the heat exchanger can be inserted through an aperture of a gear casing to provide a cooled gear assembly.
