| 摘要 |
The invention relates to a refrigerating machine which functions periodically. Said refrigerating machine consists of a thermal power amplifier which is based on the pulse tube process and a pulse tube cooler which is connected in series to the heat exchanger of said thermal power amplifier, which functions as a recooler. The thermal power amplifier consists of a compressor device, a first heat exchanger which releases heat to the environment, a regenerator, a second heat exchanger which introduces heat into the power amplifier, the heater, a pulse tube and a third heat exchanger which releases heat to the environment and to which the pulse tube cooler is connected. Said pulse tube cooler also consists of a regenerator, a heat exchanger, a pulse tube, another heat exchanger and an expander. The optimal design of the refrigerating machine for stationary operation can be determined using a vector diagram.
