Abstract
A double-walled plate heat exchanger and method of managing the same includes a first plate including a first skin, a second skin, at least two port holes, and a leakage escape path between the first and second skins for allowing leaked fluid to exit the double-walled plate heat exchanger, the leakage escape path being in contact with a leakage orifice in one of the skins, and an outer edge of the double-walled plate heat exchanger, the first plate further including a second plate in contact with the second skin.
Claims21
A double-walled plate heat exchanger comprising:
- a first plate comprising:
- a first skin;
- a second skin;
- at least two port holes;
- and
- a leakage escape path between the first and second skins for allowing leaked fluid to exit the double-walled plate heat exchanger, the leakage escape path being in contact with:
- a leakage orifice in one of the skins;
- and
- an outer edge of the double-walled plate heat exchanger;
- and
- a second plate in contact with the second skin.
A method of managing a leak in a double-walled plate heat exchanger, the method comprising allowing fluid leaked between first and second skins of a first plate in a double-walled plate heat exchanger to exit the double-walled plate heat exchanger via a leakage escape path, the leakage escape path comprising a leakage orifice, the first plate further comprising first and second port holes.
A double-walled plate heat exchanger, comprising:
- leakage escape means for allowing fluid leaked between first and second skins of a first plate in a double-walled plate heat exchanger to exit the double-walled plate heat exchanger, the leakage escape means comprising leakage orifice means for allowing the leaked fluid to exit from between the first and second skins, the first plate having at least two port holes.
