Abstract

1,233,038. Heat exchange elements. NIPPON SHINPU K.K. 28 Nov., 1968 [3 April, 1968; 20 July, 1968], No. 56515/68. Heading F4S. A heat transfer element 1 comprises a thin base sheet 2 of e.g. aluminium or copper having a large number of spaced bristle members 3 made of rigid wire material extending outwardly from one surface thereof. As shown the bristle members 3 are bent in the form of U- shaped structures which are passed through holes 4 in the base sheet 2. The bristle members 3 are held in place relative to the base sheet by means of a film 5 of material such as synthetic resin. Alternatively the base parts 3c are held in place by applying a layer of quick drying adhesive. The outwardly extending ends 3a may be bent into various configurations as required (see Figs. 3A, 3B, not shown). In use the heat transfer element 1 in the form of a strip may be wrapped and fixed e.g. by bonding around the outer surface of a tube 7 of circular or flattened cross-section. The heat transfer element 1 may also be applied to the inner surface of a tube. The bristle members 3 are protected by one or more films (6, Figs. 4, 5, not shown) of material such as synthetic resin or paper, the films being peeled off after the heat transfer element has been fixed in position.
