  • Publication number: 20220275977
    Abstract: The present disclosure relates to a vortex tube for separating a working fluid into a first working fluid and a second working fluid, the vortex tube comprising: a hot end; a cold end opposed to the hot end; a vortex generator between the hot end and the cold end, the vortex generator configured to receive a working fluid, the vortex generator comprising: a vortex chamber including a bottom wall defining a bore therethrough; and a plurality of channels configured to direct the working fluid into the vortex chamber, wherein one or more of the bottom wall and the plurality of channels are configured to direct the working fluid in a vortex motion to form a first toroidal moving away from the vortex chamber and towards the hot end; and wherein a first working fluid exits the hot end and a second working fluid is turned away from the hot end and flows through the bore to exit the cold end. The present disclosure also relates to use of the vortex tube for panel and spot cooling.

  • Patent number: 9303813
    Abstract: A method, device, and nozzle for dispensing cooled lubricant is provided. Lubricant is supplied to the nozzle through an inner lubricant tube. Cooled compressed gas is also supplied to the nozzle through a conduit which surrounds the inner lubricant tube. Cooled compressed gas from the conduit is introduced into a nozzle gas bore in the nozzle and lubricant is introduced into a nozzle lubricant bore in the nozzle. The cooled compressed gas and the lubricant are mixed at a junction between these bores, such that the lubricant is siphoned into the junction by the cooled compressed gas. The mixture of cooled compressed gas and lubricant are then dispensed from an aperture in the nozzle, preferably as a fine atomized mist of cooled lubricant.
