Abstract:
An apparatus comprising:a Stirling cooler having a hot portion and a cold portion; a first fluid heat exchanger in heat transfer relationship with said cold portion; a fluid reservoir for containing a heat transfer fluid, said fluid reservoir being connected to said first fluid heat exchanger for fluid communication therewith; a pump operative to circulate said heat transfer fluid in said fluid reservoir to said first fluid heat exchanger and back so as to maintain said heat transfer fluid at a desired temperature; a second heat exchanger connected to said fluid reservoir for fluid communication therewith, said second heat exchanger being connectable to a source of fluid to be chilled such that heat from said fluid to be chilled is transferred to said heat transfer fluid in said second heat exchanger; and a pump operative to circulate said heat transfer fluid in said fluid reservoir to said second heat exchanger and back.
