How much does a cryocooler cost?

It combines the well-tested thermodynamics of the M77 cryocooler with features developed to permit the manufacture of large-volume free- piston (linear) compressors. The price of the cryocooler is projected to be $2,000 per unit in lots of 10,000, with availability in the first quarter of 2001.

What is a cryocooler used for?

A refrigerator designed to reach cryogenic temperatures is often called a cryocooler. The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW. Some can have input powers as low as 2-3 W.

What is Stirling cryocooler?

A Stirling cryocooler utilizes the Stirling cycle to convert electricity into the movement of heat from the cold tip towards the heat rejecter. The Stirling cycle occurs 60 times/second. The result is that the CryoTel® cold tip will get down to 40K (-233°C, or -387 °F) with no load in a vacuum.

How does a pulse tube cryocooler work?

It absorbs heat from gas pumped into the pulse tube precooling it, and stores the heat for half a cycle then transfers it back to outgoing cold gas in the second half of the cycle cooling the regenerator. The pulse tube works by transporting heat against a temperature gradient in a process called surface heat pumping.

Why is liquid nitrogen called LN2?

Liquid nitrogen is the liquefied form of the element nitrogen that’s produced commercially by the fractional distillation of liquid air. Like nitrogen gas, it consists of two nitrogen atoms sharing covalent bonds (N2). Sometimes liquid nitrogen is denoted as LN2, LN, or LIN.

Is liquid nitrogen the same as dry ice?

What Is the Difference Between Dry Ice and Liquid Nitrogen? Liquid nitrogen is much colder than dry ice—usually between -346°F and -320.44°F—which also makes it more dangerous to handle. Because it’s a liquid and not a solid, it’s also more challenging to work with in many settings and can be difficult to contain.

Is it safe to eat liquid nitrogen ice cream?

The U.S. Food and Drug Administration warned people not to eat liquid nitrogen ice cream. Officials said eating liquid nitrogen could burn someone’s throat because it is so cold. In some extreme cases, it could cause internal damage to organs.

What kind of cooling system does Stirling Cryogenics use?

Who is the world leader in free piston Stirling engines?

RECENT NEWS. Sunpower Inc. Sunpower, Inc., the world leader in free-piston Stirling engine and cryocooler technology, announces the development of the DS30 cryocooler as well as the ability for select customers to purchase a DS30 Engineering Build (EB) unit.

When did Robert Stirling invent the Stirling cycle?

A Scottish minister named Robert Stirling invented the Stirling engine around 1816. Various manufacturers built Stirling engines over many years, but those engines usually had low power compared to their weight (low specific power). Although pressurizing the cycle can achieve a higher specific power, sealing of the gas often proved problematic.

What is the purpose of STI’s Sapphire cryocooler?

STI’s Sapphire Cryocooler is a compact, high performance and extremely reliable cryocooler. Using an integral-free piston Stirling cycle design, the cryocooler is currently used to cool high temperature superconducting (HTS) materials in STI’s SuperLink ® product – a high performance receiver used in the telecommunications industry.
