Abstract
A pin for a core layer of a heat exchanger, the pin being an additively manufactured pin having a sinusoidal shape between an upper and a lower sheet.
Claims16
A pin for a core layer of a heat exchanger, the pin being an additively manufactured pin having a sinusoidal shape between a first end of the pin and a second end of the pin.
A layer for a heat exchanger, the layer comprising:
- an inlet;
- an outlet;
- an upper sheet;
- a lower sheet;
- a fluid flowpath defined between the upper sheet and lower sheet and from the inlet to the outlet;
- and
- at least one pin disposed in the flowpath and connecting the upper sheet to the lower sheet;
- wherein the at least one pin is an additively manufactured pin that defines a substantially sinusoidal shape by extruded cross-section along a sine wave path between the upper sheet and the lower sheet.
5 more elements
A method of additively manufacturing a pin for layer for a heat exchanger, the method comprising:
- additively manufacturing a pin having a sinusoidal shape wherein the cross-section of the pin is extruded along a sine wave path between the lower sheet and the upper sheet.
