Abstract
1394662 Cooling of semi-conductor devices HAWKER SIDDELEY DYNAMICS Ltd 1 May 1967 [29 April 1966] 19071/66 Heading H1K [Also in Divisions F3-F4] A proximity fuse for a missile warhead and sensitive to infra red radiation comprises a semiconductor cell 15 mounted on a copper plate 14 within a vented shroud 11 having a sapphire window 19. A cooling chamber 23 is formed on the rear of the plate 14 by a frusto-conical porous walled member 21 of sintered bronze constituting a heat sink, the rear of the chamber being closed by a heat-insulating bush 22. A layer of felt 24 surrounds the sink 21 and bush 22. Refrigerant liquid is supplied to the chamber 23 by an inner pipe 25 having spray jets 27, the pipe 25 being connected to a refrigerant reservoir through a pipe 29 including an electrically controlled valve (Fig. 3, not shown). An outer pipe 26 encloses an annular space 38 with the pipe 25 and in this space is a heat exchange coil 37 connected through a pipe 36 and an electrically controlled valve to a high pressure air reservoir. The other end of the coil 37 opens into the chamber 23. One end of the space 38 is blocked at 39 and adjacent this block is an orifice 40 permitting the refrigerant to expand into the space 38. In use, to arm the missile, the valve in the pipe 29 is opened (e.g. by a time delay switch or a transmitted signal) and refrigerant sprays into the chamber 23 for three seconds. Then, the valve in pipe 36 opens and simultaneously another valve opens to vent the refrigerant reservoir. Air enters the chamber 23 through the previously cooled coil 37 and the resulting increased evaporation of the refrigerant enhances the cooling effect by inducing supercooling. The air supply flows for ten seconds. The cell 15 may comprise an indium (antimonide patch 16 deposited on a Sintox (Registered Trade Mark) substrate 17.
