Abstract

A self-compensating water-cooling jacket employs an electroformed metal bellows to adjust for substrates of varying thickness. As shown in Fig. 1, the bellows 1 is rectangular, conforming to the dimensions of the substrate 3. Water inlet and outlet connections 5 are provided. Bottom jaws 7 are provided along opposite sides of the bellows, as are finger levers 9. In use, the finger levers are pulled together so as to expand the bottom jaws, as seen in Fig. 2. The entire assembly is then clamped onto the substrate 3 to be cooled. An effective thermal grease can be added between the substrate/water jacket bond for better cooling.

Water Cooling Jacket

A self-compensating water-cooling jacket employs an electroformed metal bellows to adjust for substrates of varying thickness. As shown in Fig. 1, the bellows 1 is rectangular, conforming to the dimensions of the substrate 3. Water inlet and outlet connections 5 are provided. Bottom jaws 7 are provided along opposite sides of the bellows, as are finger levers 9. In use, the finger levers are pulled together so as to expand the bottom jaws, as seen in Fig. 2. The entire assembly is then clamped onto the substrate 3 to be cooled. An effective thermal grease can be added between the substrate/water jacket bond for better cooling.

When water coolant is injected through the inlets, the metal bellows expands to adjust to the thickness of the substrate under test.
