Leakage of fluid from a heat exchanger and fluid mixing in the case of a two fluid compact high intensity cooling heat exchanger are prevented by diffusion bonded areas of the heat exchanger formed using small locally raised borders which extend about the fluid passage or passages of the heat exchanger to form raised contact portions that experience locally high stresses during diffusion bonding thereby insuring material flow and complete bonding. The thickness of the locally raised borders is the same as or slightly greater than the tolerance of the rolled sheet material used to form the laminates of the heat exchanger whereby local deviations in thickness of the thin laminates will not result in non-bonded areas.
