ShareHOW TO ACHIEVE THE EFFICIENCY OF A GIFFORD-MCMAHON CRYOCOOLER WITH A PULSE TUBE REFRIGERATOR.
Author(s) : DAVID M., MARECHAL J. C.
Type of article: Article
Summary
THE INTEREST OF THE ORIFICE IN A PULSE TUBE IS TO EVACUATE MORE HEAT THAN IN A BASIC PULSE TUBE AND CONSEQUENTLY TO INCREASE THE COLD POWER. THE PAPER DESCRIBES AN HYBRID SYSTEM (BOTH BASIC AND ORIFICE PULSE TUBE) WHICH PERMITS TO OBTAIN A VERY GOOD EFFICIENCY: 57 K COLD TEMPERATURE WITH A 12 WATT COLD POWER AT 72 K. THE RESULT IS A 40% OF CARNOT EFFICIENCY WHEN THE REGENERATOR LOSSES ARE NOT NEGLECTED.
