An engine cooling system includes a first heat exchanger receiving a first fluid and a second heat exchanger receiving a second fluid. The second heat exchanger is located adjacent the first heat exchanger, thereby creating a stacked heat exchanger. The engine cooling system also includes a third heat exchanger receiving a third fluid. The third heat exchanger is located apart from the stacked heat exchanger. A venturi is located between the stacked heat exchanger and the third heat exchanger. An air mover is mounted to the venturi and located within the venturi. The air mover is configured to move air through the stacked heat exchanger and through the third heat exchanger. In a specific embodiment, the engine cooling system is incorporated into a vehicle, such as a skidder vehicle.

A cryoablation system for performing endometrial ablation comprising an elongated tubular cannula having a proximal end, a distal end, and a longitudinal axis, an expandable balloon extending from the distal end of the cannula and fluidly connected to a source of heat transfer fluid by at least one fluid path, a pump for circulating the heat transfer fluid into and out of the balloon, a probe handle coupled to the proximal end of the cannula and in fluidic communication with the balloon through the cannula, and a heat exchanger for varying the temperature of the heat transfer fluid, wherein the heat exchanger is fluidly connected to a secondary refrigerant source, and wherein the heat exchanger comprises an outer tubular wall and a plurality of fins extending from the tubular wall toward the interior portion of the heat exchanger.

Disclosed is a structural frame for a gas turbine engine comprising an integral fluid reservoir and air / fluid heat exchanger. A central hub includes a reservoir for storing a fluid and an outer rim circumscribes the hub. A heat exchanger is fluidly coupled to the reservoir and is in simultaneous communication with the fluid and an air stream.

An HVAC system for a vehicle having a battery pack, and a method of operation, is disclosed. The HVAC system may comprise a refrigerant loop having a first leg and a second leg, and a refrigerant compressor in the refrigerant loop. In the first leg, an evaporator provides cooling to a passenger cabin of the vehicle, an evaporator shut-off valve selectively blocks the flow of refrigerant through the evaporator, and an evaporator thermal expansion valve is upstream from the evaporator. In the second leg, a battery heat exchanger receives the refrigerant, a battery thermal expansion valve is located upstream from the battery heat exchanger, and a battery cooling shut-off valve selectively blocks the flow of refrigerant through the battery heat exchanger. The shut-off valves and compressor are controlled to control the cooling of the passenger cabin and the battery pack.

A combustor-heat exchanger system comprising a plurality of cans. Each can includes an inner cylinder and an outer cylinder forming an annular space in between, wherein the inner cylinder is configured to receive and combust a fuel and compressed oxidant to generate heat and a hot gas. The outer cylinder is configured to receive a portion of a gas lean in carbon dioxide from a turbine system and utilize the heat from the inner cylinder to generate a heated gas. The combustor-heat exchanger further includes an inlet volute along the surface of the inner cylinder configured to receive the portion of the gas lean in carbon dioxide and distribute the gas lean in carbon dioxide into an axial flow through the annular space of each can. The combustor-heat exchanger also includes an outlet volute along the surface of the outer cylinder configured to receive the heated gas from each can, a first manifold to distribute the gas lean in carbon dioxide stream into each inlet volute and a second manifold to receive the heated gas from each can and generate a hot discharge stream.
