Heat exchanger for a power connector

A charging inlet assembly for an electric vehicle comprising:

• a housing extending between a front and a rear, the housing having a chamber at the rear, the housing having a power connector at the front for receiving a charging connector, the power connector including a first terminal channel and a second terminal channel between the front and the rear;
• a first terminal coupled to the housing, the first terminal including a first mating pin at a front of the first terminal and a first cable connector at a rear of the first terminal, the first mating pin positioned in the first terminal channel for mating with the charging connector, the first cable connector positioned in the chamber at the rear of the housing, the first cable connector including a first pad configured to be terminated to a power cable;
• a second terminal coupled to the housing, the second terminal including a second mating pin at a front of the second terminal and a second cable connector at a rear of the second terminal, the second mating pin positioned in the second terminal channel for mating with the charging connector, the second cable connector positioned in the chamber at the rear of the housing, the second cable connector including a second pad configured to be terminated to a power cable;
• and
• a heat exchanger positioned in the chamber, the heat exchanger including a heat exchanger body having a first terminal interface being thermally coupled to the first pad of the first terminal and a second terminal interface being thermally coupled to the second pad of the second terminal, the heat exchanger including a coolant channel for coolant flow through the heat exchanger for actively cooling the first terminal and the second terminal, the heat exchanger including a thermally conductive separator electrically isolating the heat exchanger from at least one of the first pad of the first terminal and the second pad of the second terminal.

A power connector comprising:

• a housing extending between a front and a rear, the housing having a terminal channel between the front and the rear;
• a terminal coupled to the housing, the terminal including a mating pin at a front of the terminal and a cable connector at a rear of the terminal, the mating pin positioned in the terminal channel for mating with a charging connector, the cable connector positioned generally at the rear of the housing, the cable connector configured to be terminated to a power cable;
• and
• a heat exchanger positioned generally at the rear of the housing, the heat exchanger including a coolant channel for coolant flow through the heat exchanger for actively cooling the terminal, the heat exchanger including a heat exchanger body forming a cavity, the heat exchanger body having a terminal interface being thermally coupled to the cable connector of the terminal, the heat exchanger including a diverter wall received in the cavity adjacent the terminal interface to reduce a size of the coolant channel at the terminal interface.
