Abstract
An apparatus may include a heat exchanger and an equalizing vessel for equalizing changes in coolant volume. The heat exchanger may include an inflow for delivering coolant to the heat exchanger and an outflow for discharging coolant from the heat exchanger. The equalizing vessel may be closed off by a flexible membrane that follows changes in volume of the coolant. The equalizing vessel may include a first chamber that is in liquid communication with the inflow of the heat exchanger and a second chamber that is in liquid communication with the outflow of the heat exchanger. A filter may also be provided to filter the coolant.
