Abstract

1330837 Refrigerating HYMATIC ENG CO Ltd 4 Dec 1970 [8 Dec 1969] 59741/69 Heading F4H In a Joule Thompson cooling apparatus a supply of working fluid as gas under pressure and below its inversion temperature is supplied through a coil 11 to a nozzle 29 to produce cooling by expansion of the gas which forms a liquefied working medium, the effective area of the nozzle being controlled by a needle valve 34 under the control of bellows 35 positioned by a sensor 17 in heat exchange relationship with a body of absorbent material 40, e.g. felt or cotton wool, which is situated between the nozzle and a load 14 to be cooled. As shown, the sensor part 19 may be separated from the absorbent material by a heat conducting metal wall 46, or be spaced by a small gap therefrom or be immersed therein and includes a vapour bulb 18 which contains a liquid in equillibrium with its vapour, the pressure of which controls the operation of the valve. The sensor has a portion of annular form 16 surrounding the longitudinal axis of the apparatus so that the sensor part 19 or part 16 will be immersed by liquefied medium before the nozzle if the device is tilted about any horizontal axis, while in normal operation the sensor part 19 responds to the extent to which the absorbent material is saturated with liquid medium. A duct 45 or a funnel device directs the medium from the nozzle so as to impinge on the absorbent material.
