Abstract:
A plate heat exchanger has openings in the plates defining supply and return ducts extending through a plate stack. The supply and return ducts are hydraulically connected to flow ducts located between the plates and to a tube arranged coaxially in each of the supply and return duct. The tubes have holes in the tube wall in order to provide the hydraulic connection to the flow ducts. A simple and cost-effective plate heat exchanger which can withstand high pressures is achieved by the tubes extending through the entire stack to form a tie rod between a top side and an underside of the plate stack. The tube has a diameter corresponding to the diameter of the openings in the plates such that the tube wall is firmly metallurgically connected to at least some edges of the openings.

Claim (Index 10):
The plate heat exchanger of  claim 9 , wherein the flow ducts are hydraulically isolated from cooling fluid flow ducts arranged between the flow ducts by metallurgical joints between plates having a first flange and plates having a first opening of a diameter that is larger than the diameter of the first tube, and by metallurgical joints between plates having a second flange and plates having a second opening of a diameter that is larger than the diameter of the second tube.
