The cooling process is called freezing or fusion.

What is the cooling system?

A cooling system, structure or device employed so that the temperature of the device does not exceed the limits imposed by safety and efficiency needs. When overheated, the oil in the machine transmission loses its lubricating ability and the fluid in the hydraulic coupling or converter leaks under the pressure produced.
