摘
要:为进一步研究降低
20
K
温区单级斯特林型脉管制冷机关键部件中损失的方法,提高整
机性能,采用计算软件
Sage
对制冷机进行模拟。通过实验结果与
Sage
计算的对比对模拟程序的有
效性进行了考察,并从调相系统结构及水冷器结构方面寻找优化途径。结果表明,在单纯使用惯性管
气库调相时,计算最低制冷温度比实验值低
9K
左右;当采用双向进气与惯性管调相组合时,计算同
实验结果基本一致。最后引入虚拟的振子阻尼调相机构对制冷机的最佳性能进行研究,计算表明在
这种调相结构下,制冷机的无负荷制冷温度及
30
K
时的制冷量均可以得到比双向进气加惯性管组合
调相更优的结果。

Abstract:

tube
cooler
system
was
developed,
whose
lowest
cold
head
tern-
perature
was
22.
7 K. To
optimize
the
system
performance
further
more,
Sage
software was
used
to do
the
simulation
and
introduce
the
results.
This
passage
shows
the
effectiveness
of
Sage
by
comparing
experimen-
tal
and
results
computation.
Results
show
that
with
inertance-reservoir
as
the
phase
shifter,
the
computation-
al
result
is 9 K
lower
than
that
of
the
experiment.
In
case
of
using
double-inlet,
all
results
match
well.
Fi-
nally,
a
virtual
phase
shifter
was
introduced
to
optimize
the
system.
Computation
indicates
that
under
this
mode
of
phase
shifter,
both
the
no-load
cryogenic
temperature
and
cryogenic
power
at
30
K
can
get
better
performance
than
when
the
cooler
is
under
