| abstract | 1430627 Peltier cooling devices INTERNATIONAL PROMOTION & ENG. SA 14 March 1973 [29 March 1972 22 Nov 1972] 12362/73 Heading H1K Apparatus for applying cold to a living body comprises (Fig. 1) a cylindrical casing 1 closed by a plug 2 with a peripheral groove and sealant ring, flanged to bear against the casing end. A battery 6 connected over push switch 9 secured to a cylindrical e.g. aluminium thermal mass 13 within the casing energizes a Peltier effect thermo-e ement 14 mounted on the end of the mass 13 to present a face which develops cold for application. Mass 13 protrudes from the casing and is covered by a cap 15 retaining the mass over ring 16; with a central aperturethrough which the element 14 protrudes. Terminals 17 disposed between switch and battery and accessible through apertures enable the battery to be connected to a charger (not shown) over a clip 18 engaging the casing with connecting pins contacting the terminal 17 (Fig. 4). In a modification (Fig. 6, not shown), a pyramidal thermal mass constitutes the body of the apparatus, and is hollowed out to contain the battery. A thermoelement energized therefrom is soldered to the apex which is covered by a plastic cap apertured for the cold face. The opposite end of the body is mounted' on a base enclosing a battery charger and mains lead. A cross-member within the hollow retains the battery and has a double socket engaging plugs on the charger, while it also carries a pressel switch and an indicator lamp. In a further modification (Figs. 8, 9) a cylindrical casing 1b is supported on stand 27b, with the thermoelement 14b presenting its cold surface through an aperture of the tapered apex with a cooling mass 13b to which the hot face of the element is soldered, screwed to the outer casing with a ring of dependent radial fins 45 aligned with orifices 46 of the casing. A central motor 48 retained by the fins and ring 49 drives a fan 52 circulating coolant air from further orifices 52. Battery 6b carried in sleeve 54 is positioned below the motor, and the body rests on base 17b containing a charger connected over pins 35b and sockets 34b. A pressel switch 9b controls energization, and a reversing switch 56 controls direction of current so that the outer face of the thermoelement may alternatively develop heat. In a further modification (Figs. 10, 11, not shown) a cascade of four thermo elements of progressively decreasing sizes generates cold, and the motor drives a double fan, while a temperature indicator responds to a thermocouple in the cold applying surface. Dry batteries may replace rechargeable batteries (Fig. 12, not shown) while the device may be energized directly over a cable from a power unit comprising battery-charging circuit, reversing switch, on/off switch, and a skin temperature measuring probe; while the cold generator may incorporate a tapered, e.g. silver, applicator partly enclosed in an evacuated glass envelope (Figs. 12, 13, not shown). |
