带压力波发生器的低温冰箱系统

Cryogenic refrigerator system with pressure wave generator
Abstract:
A pressure wave generator (40) for driving one or more cryogenic refrigerator systems. The pressure wave generator (40) comprises a housing with one or more inlet/outlet ports (57,58) through which generated pressure waves of gas may pass through to drive a cryogenic refrigerator system or systems connected to the inlet/outlet ports (57,58). The pressure waves are generated by at least one pair of opposed diaphragms (41,42) located in the housing that are moveable in a reciprocating motion within the housing to create pressure waves in gas spaces (55,56) associated with each diaphragm (41,42). The gas spaces (55,56) each having associated inlet/outlet ports (57,58) through which the pressure waves may pass. An operable drive system is also provided to move the pair of diaphragms (41,42) in a reciprocating motion.
Abstract(Chinese):

一种用于驱动一个或多个低温冰箱系统的压力波发生器（40）。 压力波发生器（40）包括具有一个或多个入口/出口端口（57,58）的壳体，产生的气体压力波通过所述入口/出口端口（57,58）通过其驱动以驱动连接到入口/出口（57）的低温冰箱系统 ，58）。 压力波由位于壳体中的至少一对相对的隔膜（41,42）产生，其能够在壳体内以往复运动的方式运动，以在与每个隔膜（41）相关联的气体空间（55,56）中产生压力波 ，42）。 每个具有相关联的入口/出口端口（57,58）的气体空间（55,56），压力波可以通过这些口/出口。 还提供可操作的驱动系统以使往复运动中的一对隔膜（41,42）移动。
