Abstract

1401069 Axial-flow fans CHRYSLER UNITED KINGDOM Ltd 27 Nov 1973 [12 Dec 1972] 57324/72 Heading F1C A cooling fan assembly comprises a plastics fan having blades extending from an annulus and mounted on a hub to be driven thereby, and a non- metallic thermally insulating element or elements interposed between the hub and annulus to obstruct heat flow from the hub to the fan. The engine cooling fan shown in Figs. 1 and 2 comprises an annulus 13 of polypropylene having integral blades 14 and moulded on to the outer periphery of a flat rigid disc 16 of a heat insulating material comprising compressed asbestos fibres embedded in a resin binder. To ensure a positive drive connection with the annulus 13, the disc 16 has serrations 21, notches 23 or castellations 24 and holes 22, all of which are inter-engaged by the moulded annulus. The disc 16 is bolted to the output member 10 of a viscous coupling either at lugs 17 or at holes 18, cooling holes 19 or cooling slots 20 being provided in the latter case. The disc 16 obstructs the flow of heat from the viscous coupling to the fan. Deep recesses 15, which may contain radial strengthening ribs, assist in cobling the annulus 13. In another arrangement, Fig.4, the plastics annulus 25 has a flange 25a which interengages with a disc 26 of the insulating material via axially or radially projecting dogs (27), 28. Bolts extending through a metal plate 29, the flange 25a and the disc 26 are screwed into the coupling member 10. The dogs (27), 28 may be omitted, holes then being provided in the disc 26 for engagement with integral studs projecting from the flange 25a.
