Abstract
There is disclosed a heat exchanger comprising at least one set of channels having a proximal end and a distal end, the set of channels comprising: a first channel defined by a first skin and a wall; and a second channel defined by a second skin and the wall, wherein the wall located between the first channel and the second channel comprises a first at least one aperture to allow fluid to pass through the wall from the first channel to the second channel.
Claims19
1:
- A heat exchanger comprising:
- at least one set of channels having a proximal end and a distal end, the set of channels comprising:
- a first channel defined by a first skin and a wall;
- and
- a second channel defined by a second skin and the wall,
- wherein the wall located between the first channel and the second channel comprises a first at least one aperture to allow fluid to pass through the wall from the first channel to the second channel, and
- wherein the heat exchanger is manufactured using diffusion bonding and superplastic forming.
4 more elements
2:
- The heat exchanger according to claim 1, wherein the heat exchanger comprises an inlet port for receiving said fluid and an outlet port for allowing the fluid to exit the heat exchanger.
3:
- The heat exchanger according to claim 2, wherein the inlet port is coupled to the first channel and the outlet port is coupled to the second channel.
4:
- The heat exchanger according to claim 3, wherein the inlet port and the outlet port are arranged at the proximal end of the set of channels.
5:
- The heat exchanger according to claim 3, wherein the inlet port is arranged at the proximal end of the set of channels and the outlet port is arranged at the distal end of the set of channels.
6:
- The heat exchanger according to claim 2, wherein the set of channels comprises a third channel defined by the first skin and the wall, wherein the wall located between the second channel and the third channel comprises a second at least one aperture to allow fluid to pass through the wall from the second channel to the third channel.
7:
- The heat exchanger according to claim 6, wherein the inlet port is connected to the first channel at the proximal end of the set of channels and the outlet port is connected to the third channel at the distal end of the set of channels.
8:
- The heat exchanger according to claim 7, wherein the second at least one aperture is located towards the proximal end of the set of channels.
9:
- The heat exchanger according to claim 1, wherein the first at least one aperture is towards the distal end of the set of channels.
10:
- The heat exchanger according to claim 1, wherein the set of channels follow a non-linear path between the proximal end and the distal end.
11:
- The heat exchanger according to claim 10, wherein the first channel and the second channel are parallel curves relative to each other.
12:
- The heat exchanger according to claim 10, wherein the non-linear path is substantially sinusoidal.
13:
- The heat exchanger according to claim 1, wherein the wall is bonded to the first skin and the second skin.
14:
- The heat exchanger according to claim 13, wherein the wall is corrugated and comprises a first longitudinal section bonded to the first skin, a second longitudinal section bonded to the second skin and at least one inclined section between the first longitudinal section and the second longitudinal section.
15:
- The heat exchanger according to claim 14, wherein the inclined section is inclined at an angle of approximately 30 to 60 degrees relative to the first longitudinal section and the second longitudinal section.
16:
- The heat exchanger according to claim 1, wherein the wall has a thickness of between 0.5 mm and 6 mm.
17:
- The heat exchanger according to claim 1, wherein the first skin and the second skin are formed of a titanium alloy.
18:
- The heat exchanger according to claim 1 further comprising a plurality of sets of channels.
