A heat transport device comprises first flow passages through which a first fluid flows, and second flow passages through which a second fluid flows, wherein a cross-section A satisfying the following Requirement 1 to Requirement 3 can be achieved. Requirement 1 is that the cross-section A is a cross-section perpendicular to the second flow passages. Requirement 2 is that the holes of the second flow passages are disposed so as to be aligned in the left-right direction and to form layers in the up-down direction; and when comparing layers with holes adjacent in the up-down direction, the holes of the second flow passages are not disposed at the same position in the left-right direction. Requirement 3 is that the first flow passages exist between the layers with holes adjacent in the up-down direction, and the first flow passages meander in the up-down direction so as to avoid the holes of the second flow passages in the layers with holes that are sandwiched in the up-down direction.

An extracorporeal blood cooling or heating circuit includes an intravenous catheter for withdrawing a patient's blood coupled to a combined pump/heat exchanger device. One or more sensors are provided upstream and/or downstream of the pump/heat exchanger device for measuring pressure, temperature, fluid flow, blood oxygenation, and other parameters, A controller is operative!}′ coupled to the pump/heat exchanger device and the one or more sensors to control the speed of the pump inside the pump/heat exchanger device and regulate the blood temperature by controlling the operation of the heat exchanger. The combined pump/heat exchanger device includes a housing having at least one inlet and at least one outlet, a pump portion defining a blood circuit inside the housing, and a heat exchanger portion contained within the housing for selectively heating or cooling the blood.

Heat exchanger fins and heat exchangers are disclosed. The heat exchanger fins disclosed herein comprise louvers and winglet-type vortex generators arranged to improve heat transfer efficiency.

A heat exchanger includes a first plate defining a first plurality of undulations that extend along a first axis and a second axis, and a second plate defining a second plurality of undulations. The second plate is spaced apart from and coupled to the first plate to define a first fluid flow passage. A first flow area of the first fluid flow passage is constant from a first inlet to a first outlet. The heat exchanger includes a third plate defining a third plurality of undulations. The third plate is spaced apart from and coupled to the second plate to define a second fluid flow passage. The second fluid flow passage is discrete from the first fluid flow passage. A second flow area of the second fluid flow passage is constant from a second inlet to a second outlet.

An energy recovery system and a method of recovering energy are disclosed. In one arrangement, an exhaust gas conduit system guides a flow of exhaust gas generated by a combustion process. A heat exchange fluid circuit guides a flow of a heat exchange fluid. An electrical generator generates electrical power from the flow of heat exchange fluid. The heat exchange fluid circuit is configured so that heat is transferred from the exhaust gas to the heat exchange fluid while the exhaust gas is flowing through the exhaust gas conduit system.

A heat exchanger module includes a first heat exchanging body including at least one first through hole and a second heat exchanging body including at least one second through hole. The second heat exchanging body is configured to be coupled to the first heat exchanging body, and an accommodation hole is provided between the first heat exchanging body and the second heat exchanging body by the first heat exchanging body and the second heat exchanging body being coupled together.

A heat exchanger includes a plurality of heat exchange tubes arranged into a first row of tubes and a second row of tubes. A fixed mount fixedly positions the first row of tubes, and a movable mount makes the second row of tubes movable between an aligned position in which tubes in the second row are aligned with tubes in the first row, creating a linear flow path for the fluid through the tubes, and a non-aligned position in which tubes in the second row are not aligned with tubes in the first row, creating a curvilinear flow path for the fluid through the plurality of tubes. Heat is exchanged between the first fluid and a second fluid passing through the plurality of heat exchange tubes. The heat exchanger may be employed as an HRSG in a combined cycle plant, among other applications.

A heat exchanger including a gas inlet through which a combustion gas flows in and a gas outlet through which the combustion gas flows out is provided. The heat exchanger includes a housing in which the gas outlet is formed, a partition member, and a plurality of heat transfer tubes accommodated in the housing. The partition member is mounted in the housing so that there is a portion in which a flow area of the combustion gas is smaller than that of the gas inlet between the gas inlet and the gas outlet.

An extracorporeal blood cooling or heating circuit includes an intravenous catheter for withdrawing a patient's blood coupled to a combined pump/heat exchanger device. One or more sensors are provided upstream and/or downstream of the pump/heat exchanger device for measuring pressure, temperature, fluid flow, blood oxygenation, and other parameters. A controller is operatively coupled to the pump/heat exchanger device and the one or more sensors to control the speed of the pump inside the pump/heat exchanger device and regulate the blood temperature by controlling the operation of the heat exchanger. The combined pump/heat exchanger device includes a housing having at least one inlet and at least one outlet, a pump portion defining a blood circuit inside the housing, and a heat exchanger portion contained within the housing for selectively heating or cooling the blood.

The invention relates to a novel solid heat exchanger module containing a plurality of heat exchanger tubes having a particular shape and being arranged in a special manner.
