Rotary heat exchanger and system thereof

A cooling system of a vehicle, comprising:

• an engine for generating power;
• a pump for pumping a fluid;
• and
• a first rotary heat exchanger for cooling the fluid, the first rotary heat exchanger manufactured by a three-dimensional printing process and comprising:
• a hub configured to be rotated about a rotational axis defining an axial direction;
• a fan comprising a plurality of fan blades integrally coupled to the hub and extending radially outwardly therefrom, wherein each fan blade comprises a leading edge and a trailing edge;
• a heat exchanger comprising a plurality of heat exchanger sections, the heat exchanger including a plurality of cooling fins for receiving a flow of air from the fan;
• and
• a rotary manifold coupled to the hub, the rotary manifold comprising a fluid passage defined therein for conveying the fluid from the pump to the heat exchanger;
• wherein each of the plurality of heat exchanger sections comprises a corresponding front surface that extends from a location adjacent the trailing edge of one corresponding fan blade and the leading edge of another corresponding fan blade;
• and
• wherein the location adjacent the trailing edge of one corresponding fan blade and the location adjacent the leading edge of the other corresponding fan blade are offset from one another in the axial direction;
• and
• wherein, the first rotary heat exchanger is rotatably driven to direct the air through the plurality of cooling fins to reduce a temperature of the fluid passing through the heat exchanger.

A rotary heat exchanger, comprising:

• a hub configured to be rotatably driven by a shaft about a rotational axis defining an axial direction;
• a fan comprising a plurality of fan blades integrally coupled to the hub and extending radially outwardly therefrom, wherein each fan blade comprises a first edge and a second edge, wherein one of the first edge or the second edge is a leading edge of the fan blade, and wherein the other of the first edge or the second edge is a trailing edge of the fan blade;
• and
• a heat exchanger comprising a plurality of heat exchanger sections, the heat exchanger including a plurality of cooling fins for receiving a flow of air from the fan;
• wherein each heat exchanger section of the plurality of heat exchanger sections is integrally formed with a corresponding first fan blade of the plurality of fan blades and extends from a location adjacent the first edge of the corresponding first fan blade to the second edge of a corresponding second fan blade of the plurality of fan blades, and wherein the first edge of the corresponding first fan blade is offset from the second edge of the corresponding second fan blade in the axial direction;
• wherein each heat exchanger section comprises a front surface defined by the plurality of cooling fins, and wherein the front surface of each heat exchanger section extends in the axial direction.
