Patent ID: 8025097

Claim:
A temperature set and control apparatus for a device that comprises: a heat transfer apparatus configured to thermally contact the device, the heat transfer apparatus having an apparatus intake to receive thermal transfer fluid, an apparatus exhaust to output thermal transfer fluid, and a conduit to conduct thermal transfer fluid from the apparatus intake to the apparatus exhaust through the heat transfer apparatus; a first thermal control circuit configured to flow a first thermal transfer fluid therein continuously at a first temperature, and a second thermal control circuit configured to flow a second thermal transfer fluid therein continuously at a second temperature; and a fluid switch block fluidically connected to the first and second thermal control circuits and fluidically connectable to the heat transfer apparatus, the fluid switch block being activatable to a plurality of states wherein: in a first state wherein only the first thermal transfer fluid flows through the heat transfer apparatus, the fluid switch block simultaneously causes: (a) the first thermal transfer fluid continuously flowing in the first thermal control circuit to flow continuously from the first thermal control circuit into the apparatus intake, and from the apparatus exhaust continuously back into the first thermal control circuit, and (b) the second thermal transfer fluid continuously flowing in the second thermal transfer fluid to flow in the second thermal control circuit without flowing into the apparatus intake; and in a second state wherein only the second thermal transfer fluid flows through the heat transfer apparatus, the fluid switch block simultaneously causes: (a) the first transfer fluid continuously flowing in the first thermal control circuit to flow in the first thermal control circuit without flowing into the apparatus intake, and (b) the second transfer fluid continuously flowing in the second thermal transfer fluid to flow continuously from the second thermal control circuit into the apparatus intake, and from the apparatus exhaust continuously back into the second thermal control circuit.
