A plate heat exchanger includes a plurality of heat transfer plates stacked together and each having openings at four corners thereof. The heat transfer plates are partially brazed together such that a first flow passage through which first fluid flows and a second flow passage through which second fluid flows are alternately arranged with one of the heat transfer plates disposed therebetween, openings at the four corners being connected forming first headers through which the first fluid enters and is discharged and second headers through which the second fluid enters and is discharged. At least one of two heat transfer plates between which the first flow passage or the second flow passage is disposed is formed by a pair of metal plates stacked together. The metal plate adjacent to the second flow passage is thinner than the metal plate adjacent to the first flow passage.

A heat transfer apparatus includes a first chamber horizontally offset from a second chamber to form an upper housing and a lower housing. Preferably, the two chambers do not overlap. The heat transfer apparatus may include a heat exchange interface including a cooler plate fixed to a bottom surface of the lower housing. The heat exchange interface may absorb heat from a proximate heat source and transfer the absorbed heat to an inner surface of the lower housing. The apparatus includes a pump including an impeller and a stator disposed therein. The lower housing may separate the impeller from the stator so that the stator is isolated from the impeller by a surrounding casing. A liquid coolant may be circulated from an inlet, over the heat exchange interface and out to an outlet to remove heat from a processer proximate to the heat exchange interface.
