ABSTRACT
While
the life of a cryocooler is guaranteed under the manufacturers specification,
the manufacturer is constantly faced with the problem of trying to determine
cooler life for customers specific applications.An
attempt has been made to estimate cooler life based on a Watt-Hour approach
proposed by Scott Miskimins1.In
the current paper, the total life of a cooler in Watt-Hour is expressed
as a function of initial power and the failure criterion.BEI
is currently conducting two life tests on the 0.5 W Stirling cooler (B512),
with various heat loads at 78K (at room temperature ambient).Correlation
of the experimental life test data with the theory will be discussed in
detail, together with life estimate of operating the cooler at conditions
other than that of the life tests, namely, high and low ambient temperatures,
different heat loads and coldtip temperatures, etc. Do You Know Someone Who Needs A Job in Engineering, Physics or Chemistry? About the author- Dr. Sidney Yuan is a consultant in the field of Low Temperature Physics and Cryogenics, and has written a Book on Cryogenics and published extensively in the field. E-Mail.
