Abstract

See full text

A cryocooler is described that can include a pressure wave generator, and a refrigeration device (for example, a coldhead), which can be used to liquefy a gas when the gas is exposed to a surface of the refrigeration device. The pressure wave generator can include one or more motors. Each motor can include a stator, and at least one electrical coil wound around a portion of the stator. The electrical coil can generate a reversing magnetic field when alternating electric current is passed through the electrical coil. The motor can further include a pressurized container that can be placed within the space enclosed by the stator, and a piston that can be placed inside the pressurized container. The stators can be placed external to the pressurized container. The piston is made by combining magnets that have opposite and transverse polarities, and are combined adjacently on a common reciprocating axis.
