Providing of the hydrophobic material on at least a portion of the exterior surface of the wall of the heat exchanger improves the efficiency of the heat exchanger.

At least one of the heat exchanger and the gas exchanger may be configured to provide a circumferential blood flow through the heat exchanger and/or gas exchanger.

The secondary heat exchanger is positioned above the primary heat exchanger.

The exclusive design of the heat exchanger ensures very high efficiency (94-96%) and easy maintenance.

Electromagnetic radiation is guided from the outside of the heat exchanger (6) through the heat exchanger (6) and further out of the heat exchanger (6).

The exclusive design of the heat exchanger ensures very high efficiency (94-96%) and easy maintenance.

Heat exchanger featuring an exclusive design that guarantees high efficiency (94-96%) and easy maintenance.

The inner heat exchanger is, at least partly, surrounded by the outer heat exchanger.

The heat exchanger is arranged around the manifold body, and the oxygenator around the heat exchanger.

This provides greater heat transfer capabilities and reduced pressure losses, resulting in an increased overall heat exchanger efficiency.

The outdoor heat exchanger (4) is connected with the coolant heat exchanger (3).

When the exchanger is used as the evaporator 1, the top surface of the turn tank 3 can be drained of water with an improved efficiency.

The parallel-flow heat exchanger is the heat exchanger at the first step that the coolant first flows into in the indoor heat exchanger.

The flow through the heat exchanger (18) is parallel to the width of the heat exchanger (18).

The heat exchanger may contribute to the reduction of the manufacturing cost, may provide high heat transfer performance and may prevent a coolant leak.
