Abstract
A heat exchanger includes a flow channel operatively connecting a channel inlet to a channel outlet to channel fluid to flow therethrough. The flow channel is defined at least partially by a shape change material. The shape change material changes the shape of the flow channel based on the temperature of the shape change material.
Claims15
A heat exchanger, comprising:
- a flow channel operatively connecting a channel inlet to a channel outlet to channel fluid to flow therethrough and defined at least partially by a shape change material, wherein the shape change material changes a shape of the flow channel based on a temperature of the shape change material, wherein the flow channel is defined by a plurality of wires, at least one of which including the shape change material, wherein one or more of the wires has a first shape at a first temperature and a second shape at a second temperature, wherein the first shape is a step-like rectangular shape including a first vertical portion, a second vertical portion, and a horizontal portion extending between the first and second vertical portions, wherein the second shape includes a partially bent portion, wherein the partially bent portion includes a partially bent portion of the horizontal portion.
A heat exchanger, comprising:
- a flow channel operatively connecting a channel inlet to a channel outlet to channel fluid to flow therethrough and defined at least partially by a shape change material, wherein the shape change material changes a shape of the flow channel based on a temperature of the shape change material, wherein the flow channel is defined by a mesh of shape change wires, wherein the mesh of wires has a first shape at a first temperature and a second shape at a second temperature, wherein the first shape is a step-like rectangular shape including a first vertical portion, a second vertical portion, and a horizontal portion extending between the first and second vertical portions, wherein the second shape includes a partially bent portion, wherein the partially bent portion includes a partially bent portion of the horizontal portion.
