Apparatus for cooling a tubular thin film of thermoplastic resin in a melted state is described. The apparatus is capable of cooling the thin film from both the inside and the outside thereof while setting its diameter by interposing the film between the mandrel and an external circular coolant storage tank. The mandrel has a cylindrical shape and is connected with the lower side of a circular-shaped extruding die wherein the film is extruded downward from a circular slit in the die. The mandrel...

There is provided a cooling chamber which communicates with a nozzle pipe. A heat absorption portion is formed on an outer peripheral surface of an expansion chamber of a cryopump and the heat absorption portion is disposed inside the cooling chamber. For example, ordinary temperature nitrogen gas is supplied to the cooling chamber as a cooling medium, the heat of the nitrogen gas is absorbed by the heat absorption portion of the cryopump, and then the nitrogen gas is jetted from a tip end openi...

In a cooling apparatus for cooling an object by means of expanding a pressurized gas which is precooled below its inversion temperature, the pressurized, precooled gas is passed through a depressurization outlet and thereby expanded in a manner such that a gas jet exits from the depressurization outlet and is directed towards a surface of the object to be cooled. This surface has a central impingement area which is impinged upon by the gas jet and which is surrounded by a plurality of spiral-sha...

One aspect of the invention is a cooling pillow comprising a flexible pouch and thermal transfer fluid composition hermetically filled in the pouch. A second aspect of the invention is a cooling device which comprises a pad having a flexible pouch and a thermal transfer fluid composition hermetically filled in the pouch, and means for holding the pad therewith to bring the pad in contact with the human body. The fluid composition comprises a mixture of fine particles of hard or graphitic carbon ...

For enhanced cooling power in a beverage vending machine the compressor is arranged in a recess of the apparatus housing, and the condenser in the form of a coil-shaped tube, is arranged in a convection shaft connected to the recess. One wall of the shaft is formed by the rear wall of the housing. Inside the shaft the tube coil of the condenser is disposed diagonally upwards in the direction of the rear wall of the apparatus housing.

A cooling device for use with liquids in open containers, the device containing a freezable material. The cooling device is configured to have a distal end for immersion in the container, a proximal end to be positioned at the surface of the liquid, and a tapered portion whereby the maximum cross-sectional diameter of the tapered portion occurs at the distal end, with the cross-sectional dimension progressively decreasing towards the proximal end.

There is provided an aerofoil 11 having a passage 17 supplied with cooling fluid from passage 13. When the leading edge area 14 of the aerofoil 11 erodes/corrodes the passage 17 becomes exposed so that the cooling fluid effects film cooling of the leading edge area.

A portable personal cooling apparatus comprising: an exterior surface of fibrous material having a fluid holding capacity sufficient to allow continuous evaporation of a fluid; an interior surface of waterproof material adapted to avoid wetting of the object to be cooled from the fluid on the exterior surface; a fluid container on one of said surfaces for distributing the fluid to the fibrous material; a fluid collector on one of said surfaces for collecting the accumulated unevaporated fluid; a...

This invention relates to a cooling system for industrial equipment such as, for example, controlled start transmission gear reducer. The cooling system comprises a fan disposed on the rotatable shaft of the equipment for rotation in either direction and a fan shroud disposed about the fan for directing air currents generated by said fan through a connecting duct to an item or area to be cooled such as clutch. The ducting is connected to said fan shroud by means of an outlet duct which is substa...

In this invention, a cooling tower pack comprises a plurality of pack elements, each of which in plan has a stepped corrugate shape with a series of bridge portions separated by webs, each element in side elevation having a curved corrugate shape, and each element having small lands which are abutted by adjacent elements and thereby separate the elements and avoid large face-to-face contiguity areas, the lands causing only a minimum of crevice area between the adjacent elements of the pack.
