Cold Finger

STFC has developed a high performance Displacement type Stirling cycle cryogenic cooler consisting of a displacer cylinder extending axially between warm and cold ends with a regenerator inside that circulates an operating fluid with flow shapers in place to improve heat transfer. STFC invites technical and commercial partners for this technology.

DESCRIPTION

The innovative technology reveals a high performance displacement type Stirling cycle cryogenic cooler which may be used in cooling subsystems for sensors and focal plane arrays n commercial and laboratory applications. Its lightweight and maintenance free virtues make it suitable for space based applications.

The cooler comprises of a cylinder extending between warm and cool ends with a regenerator arranged to reciprocate axially within the cylinder. This arrangement and movement provides a heat exchanging fluid path for an operating fluid between the warm and cold ends, with a flow shaper element at the cold end to increase turbulence and thus induce forced convection. This increases the heat transfer co-efficient at the cold end.

 

INNOVATIONS

  • Displacer cylinder extending axially between warm and cold ends

  • A regenerator arranged to reciprocate axially within the cylinder and thus provide a heat exchanging path.

  • Flow shapers at the cold end to induce forced convection.

 

ADVANTAGES

  • Quick Response

  • High Heat transfer co-efficient due to greater turbulence.
