Abstract

A heat transfer assembly is disclosed which comprises at least one wall (1, 2, 3) which is adapted to separate a first fluid at a first temperature from a second fluid at a second temperature, and at least one fiber member (6, 7, 8, 9) or plurality of them, each fibre member (6, 7, 8, 9) including at least one elongate fibre which extends substantially axially along the fiber member (6, 7, 8, 9) from the first fluid through the wall (1, 2, 3) and into the second fluid whereby in use heat is transferred from the first fluid to the second fluid or vice versa, and the entire heat transfer assembly or a part of it is assembled as a single unit by sewing/weaving/stitching technique.

Claims

1. A heat transfer assembly, comprising:

a plurality of channel walls, each said channel wall being made from a textile fibrous material formed of independently displaceable elongated fibres,

at least a first channel and a second channel being defined at opposing sides of at least one of said plurality of said channel walls, a first fluid at a first temperature being received in said at least first channel, and a second fluid at a second temperature being received in said at least second channel separated from the first fluid by said at least one of said plurality of the channel walls, and

a plurality of fibre members, each of said plurality of fibre members including at least one elongated thermally conductive fibre extending substantially axially along said each fibre member between the first fluid and the second fluid through said plurality of the channel walls, thus retaining relative disposition between said channel walls to form a structurally enhanced integral heat transfer unit, and for transferring heat between the first fluid and the second fluid.

2. The heat transfer assembly according to claim 1, wherein said first and second channels have at least one triangularly shaved cross-section thereof.

3. The heat transfer assembly according to claim 1, further comprising a stack of said channel walls, either of said first and second channels being defined between adjacent of said channel walls.

4. The heat transfer assembly according to claim 3, further including at least one structural member positioned in said first and second channels.

5. The heat transfer assembly according to claim 4, wherein said at least one structural member includes a corrugated sheet extending across the width of said first and second channels.

6. The heat transfer assembly of claim 1, wherein said at least one channel wall is formed from said elongated fibres by sewing/weaving/stitching said elongated fibres.

7. The heat transfer assembly of claim 1, wherein an angle between said at least one elongated fibre member and said at least one channel wall is an obtuse or acute angle.

8. The heat transfer assembly of claim 3, wherein said channel walls and said fibre members form a flexible structure of a changeable controlled shape.
