摘要：
A heat exchanger 100 having a core comprising first fluid channels 10, 30, 50, 70 for guiding a first fluid, a manifold 2 for first fluid input and a second manifold 4 for first fluid output. Each of the first fluid channels comprises a plurality of spur conduits 8 interconnecting with at least one other of the first fluid channels. The first fluid input manifold comprises an input port (602a, Fig.6) which communicates with an input chamber for the first fluid, the chamber branching to form a plurality of first-fluid core-input channels. The first fluid output manifold 4 comprises a plurality of first-fluid core-output channels which lead into an output chamber communicating with an output port. Each first fluid channel communicates between a respective first-fluid core-input channel and a respective first-fluid core-output channel. The heat exchanger may further comprise second fluid channels 20, 40, 60 for guiding a second fluid, a manifold 4 for second fluid input and a manifold 2 for second fluid output. The first and second fluid channels may be interleaved. The spur conduits may have an elongate or elliptical cross section.

CLAIMS
7. A heat exchanger comprising:
a core comprising first fluid channels, for guiding a first fluid, wherein each of the first fluid channels comprises a plurality of spur conduits interconnecting with at least one of another of the first fluid channels;
a manifold for first fluid input comprising an input port which communicates with an input chamber for a first fluid, the chamber branching to form a plurality of first-fluid core-input channels; and
a manifold for first fluid output comprising a plurality of first-fluid core- output channels which lead into an output chamber communicating with an output port,
wherein each first fluid channel in the core communicates between a respective first-fluid core-input channel and a respective first-fluid core-output channel.
2. A heat exchanger according to claim 1 wherein:
the core further comprises second fluid channels, for guiding a second fluid, wherein each of the second fluid channels comprises a plurality of spur conduits interconnecting with at least one of another of the second fluid channels,
and wherein the heat exchanger further comprises:
a manifold for second fluid input comprising a single input port which communicates with an input chamber for the second fluid, the input chamber branching to form a plurality of second-fluid core-input channels;
a manifold for second fluid output comprising a plurality of second-fluid core-output channels which lead into an output chamber communicating with an output port; and
wherein each second fluid channel communicates between a respective second-fluid core-input channel and a second-fluid core-output channel.
3. A heat exchanger according to claim 1 or claim 2 wherein each of the plurality of the spur conduits is inclined to at least one of the fluid channels which it interconnects by between 30 and 60 degrees
4. A heat exchanger according to any of the preceding claims wherein each of the plurality of the spur conduits defines an outer wall and a bore for guiding fluid, wherein the outer wall has an elongate cross section, thereby defining a shorter aspect and a longer aspect.
5 A heat exchanger according to claim 4 wherein each of the plurality of spur conduits is inclined to a predetermined flow direction.
6. A heat exchanger according to claim 4 or 5 wherein the outer wall is configured such that the longer aspect is generally aligned with a predetermined fluid flow direction.
fl. A heat exchanger according to either of claims 4, 5, or 6 wherein the outer wall is elliptical.
8. A heat exchanger according to any one of claims 4 to 7 wherein the outer wall has an aspect ratio of 4:1 to 1.5:1.
9. A heat exchanger according to claim 8 wherein the outer wall has an aspect ratio of 2.5:1 to 1.5:1.
10. A heat exchanger according to any one of the preceding claims wherein the first fluid channels and second fluid channels are interleaved.
11. A heat exchanger according to any one of the preceding claims wherein one of the first fluid manifolds and one of the second fluid manifolds are integrated such that channels from the first fluid manifold are interleaved with channels from the second fluid manifold.
12. A heat exchanger according to claim 10 wherein the manifold for first fluid input is integrated with the manifold for second fluid output, the first-fluid core-input channels and the second-fluid core-output channels thereby being interleaved.
13. A heat exchanger according to claim 10 wherein the manifold for first fluid input is integrated with the manifold for second fluid input, the first-fluid core- input channels and the second-fluid core-input channels thereby being interleaved.
