The liquid heat exchanger includes a liquid circulation path through which liquid coolant flows to exchange heat with the liquid heat exchanger. Air flows over each of the air heat exchangers to exchange heat with the respective air heat exchanger. A first thermoelectric module is thermally coupled on a first side with a first side of the liquid heat exchanger and on a second side with a first air heat exchanger to transfer heat between the air heat exchanger and the liquid heat exchanger. A second thermoelectric module is thermally coupled on a first side with a second side of the liquid heat exchanger and on a second side with the second air heat exchanger to transfer heat between the air heat exchanger and the liquid heat exchanger.
