Abstract: A plate heat exchanger includes a plurality of plate pairs for providing a flow path for two fluids. The plate heat exchanger has an inlet and an outlet for each of the two fluids, wherein facing surfaces of two adjacent plate pairs of the plurality of plate pairs defines a flow path for a first fluid. The opposite surface of one of the two adjacent plate pairs and a facing surface of another adjacent plate pair from the plurality of plate pairs provides a flow path for a second fluid. The first fluid and the second fluid flowing along their respective flow paths are maintained in thermal communication with each other. A predetermined vent path is formed in at least one of the facing surfaces of each plate pair capable of venting each fluid exterior of the heat exchanger.
