Computer cooling. A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background. A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components. Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.
Liquid nitrogen has a boiling point of about −196 °C (−321 °F; 77 K). It is produced industrially by fractional distillation of liquid air. It is a colorless, mobile liquid whose viscosity is about one-tenth that of acetone (i.e. roughly one-thirtieth that of water at room temperature). Liquid nitrogen is widely used as a coolant.
Coolant. A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical ...
Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens.
Freeze brand. A feral horse (mustang) captured by the Bureau of Land Management and freeze branded using the Alpha-angle system. From left to right the brand says the horse is registered to the Federal Government, was born in the year 2000 and carries the registration number 012790, indicating that it was branded at a BLM facility in Oregon.
Cryogenics technology using liquid nitrogen and CO 2 has been built into nightclub effect systems to create a chilling effect and white fog that can be illuminated with colored lights. Cryogenic cooling is used to cool the tool tip at the time of machining in manufacturing process. It increases the tool life.
