The cooling body is designed to optimize the cooling effect by increasing the surface area of the liquid fit for human consumption in contact with the cooling body.

The coolant delivery system is in communication with the coolant supply and is operable to deliver a micro-controlled pulse of coolant to the distal end.

Preferably, the coolant flows with turbulent flow through the cooling device attributed to the travelling mould.

The coolant delivery elements are in communication with the coolant supply and are operable to deliver a micro-controlled pulse of coolant to the distal end.

The bottom surface of the cooling element is exposed and the material of the cooling element is different from the material of the leads.

A cooling-type fabric material.

A self-cooling beverage container is disclosed.

The apparatus is also provided with a cooling fluid supply system (20) for supplying an insulating cooling fluid into the housings (6a, 6b).

Nitrogen gas (16), a kind of inert gas, is introduced as cooling gas from a cooling gas inlet (12) into the flow path (17).

The TBB 122 is cooled, thereby cooling the blades.

A self-contained heating and cooling orthopaedic brace is described.

A cooling medium is guided through each channel.

In one example, this is by cooling the substrate.

A heating device (32) is associated with the pathways that conduct warming air, and the pathways that conduct cooling air are associated with a source of cooling air.

A garment is provided which is worn by a wearer and which actively cools the wearer.
