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 18):
The plate heat exchanger of  claim 17 , wherein the plurality of plates comprises:\n a plurality of first plates, each of which is provided with a flange along a continuous edge of at least one of the first and second opening, said flange being metallurgically joined to the corresponding one of the first and second tubes; and a plurality of second plates interleaved with the first plates, each of the second plates being metallurgically joined to an adjacent one of the plurality of first plates at a first location adjacent to and radially outward of the first tube and at a second location adjacent to and radially outward of the second tube in order to hydraulically separate the first plurality of closed flow ducts from the second plurality of open flow ducts.
