Abstract (en)

[origin: EP0803687A1] At the warm zone, a mounting plate (4), screwed (48) and sealed (19) to the pulsed gas compressor (50), has an integral projecting cylinder (2) with a cold-zone base (22). Against this the cooled item typically an opto-electronic component (21) is held, e.g. by adhesive. An insulating jacket (1), evacuated or gas-filled, encloses the finger (2,22). A ducted (11, 12) block (10) screws into a neck (17), on the plate, fitting into the compressor reservoir chamber. Its integral sleeve (3), with warm and cold-zone heat exchangers (9,8), enters the skirt (2), the annular space between containing a rolled mesh regenerator (5), percolated by gas ducted (61, 39, 42, 43, 46, 45) from the compressor's compression chamber. Fingers for Stirling cycle coolers are similar, but the inner sleeve (3), extending up through the block (10), accommodates the reciprocating displacer piston.
