(54)	Plate heat exchanger with tension ties

(57) A plate heat exchanger (100) includes a stack of main plates (110) having ridges and troughs to direct first and second flows of fluids through cavities between the main plates (110) to exchange heat between the fluids while maintaining the first and second flows of fluids separate from each other. The plate heat exchanger (100) includes a first end plate (120) stacked at one end of the stack of main plates (110) and a second end plate (130) stacked at an opposite end of the main plates (110). Tension ties (140) mechanically connect to each of the first and second end plates (120, 130) through the stack of main plates (110).
