Coolant refresh device for coolant distribution unit

A coolant distribution unit comprising:

• a housing;
• a coolant refresh device configured to direct coolant from a coolant source into the coolant distribution unit and to discharge coolant out of the coolant distribution unit so as to circulate coolant between the coolant distribution unit and an external component;
• a heat exchanger disposed in the housing and configured to change a temperature of coolant;
• and
• a port fluidly coupled to the heat exchanger,
• wherein the coolant refresh device comprises an interface configured to couple to the port to define a first chamber and a second chamber in the port such that the coolant refresh device is configured to direct coolant to the external component via the first chamber and to receive coolant from the heat exchanger via the second chamber, and wherein the coolant refresh device is configured to discharge coolant from the heat exchanger out of the coolant distribution unit.
