Patent ID: 7100389

Claim:
An apparatus for controlling the temperature of an electronic device under test, said apparatus comprising: a refrigeration system including a compressor and a condenser, said refrigeration system being operative to circulate a refrigerant fluid will change between gaseous and liquid states to alternately absorb and release thermal energy; an evaporator head connected into said fluid flow loop, said evaporator head having a temperature controlled surface; a support structure in spaced apart relation to said evaporator head, said support structure having a manifold configured to route said refrigerant fluid between said evaporator head and components of said refrigeration system; a mechanical isolation assembly situated between said evaporator head and said support structure so as to compensate for variations in the planar orientation of said device under test; and said mechanical isolation assembly including an inflow bellows and an outflow bellows located side by side to one another, inflow bellows providing inflow of said refrigerant fluid from said evaporator head to said support structure.
