Abstract
The invention relates to a heat exchanger tube (1) which is a component of a heat exchanger of an oxygenator. The heat exchanger tube (1) comprises a tube body (2) consisting of thermoplastic polyurethane (PTU). The tube body (2) has a Shore hardness of greater than 60 D. This results in a heat exchanger tube optimised for use in a heat exchanger of an oxygenator.
Claims6
A heat exchanger tube for a heat exchanger of an oxygenator, comprising
- a tube body made of a thermoplastic polyurethane (TPU) that is free of gel particles,
- wherein the tube body (2) has a Shore hardness greater than 60 D, and
- wherein a wall thickness of the tube body deviates less than 0.02 mm along a length of the tube, and
- wherein the wall thickness of the tube body is less than 0.07 mm, and
- wherein the heat exchanger tube has a dielectric strength of at least 10 kV.
