Large scale field erected air cooled industrial steam condenser having heat exchanger panels with primary and secondary condenser sections, in which the secondary condenser section comprises 10% or less of the total heat exchanger, and in which the tubes of the primary condenser sections have narrowed outlet orifices having an area that is 50% or less than the cross-sectional area of a corresponding tube. The invention permits the reduction of secondary condenser tubes while reducing the outlet header pressure sufficiently to minimize backflow, sweep non-condensables and prevent the formation of dead zones.

A heat exchanger includes a conduit of a first aluminum alloy and a plurality of fins in thermally conductive contact with the exterior of the conduit. The fins include a second aluminum alloy comprising from 0.005 wt. % to 0.1 wt. % of at least one alloying element selected from tin, barium, indium, mercury, and gallium.

A heat exchanger includes a shell, a coiled tube, and a swirler. The shell has an inlet and an outlet and forms a cavity. A first of a liquid refrigerant and a vapor refrigerant enters the inlet of the shell. The coiled tube is positioned within the cavity and is connected to an inlet tube from outside the shell and an outlet tube to outside the shell. A second of the liquid refrigerant and the vapor refrigerant enters the inlet tube of the coiled tube. The swirler is arranged adjacent the inlet of the shell and is dimensioned to distribute the first of the liquid refrigerant and the vapor refrigerant across the coiled tube.

A heat dissipation device includes a base plate and a plurality of fins arranged on the base plate. Each fin includes a fin body including a first metal sheet and a second metal sheet coupled to each other, wherein the fin body is curved and includes a first portion and a second portion transverse to the first portion, an evaporation channel defined in the first portion, one or more connecting channels disposed in the first portion and in fluid communication with the evaporation channel, a condensation channel defined in the second portion, and one or more auxiliary channels disposed in the second portion and in fluid communication with the one or more connecting channels and the condensation channel.

A heat exchanger has flow channels for coolants, which flow channels include turbulence elements having a different flow resistance depending on a direction of a flow, wherein the flow can be passed through the heat exchanger in different directions. As part of a method of operating the heat exchanger, the heat exchanger is flowed through in different directions using a pump that can be operated in different directions.

A temperature control body housing includes a monolithic housing middle portion penetrated by one or more than one fluid canal, each fluid canal being completely bounded on four sides by respective walls monolithically connected to outer walls of the housing middle portion; a first housing end cap and a second housing end cap between which the housing middle portion is disposed; wherein the first housing end cap has a first fluid port and either the first housing end cap or the second housing end cap has a second fluid port, and wherein the first fluid port and the second fluid port are fluidly connected to each other by means of the one or more fluid channels.

A heat dissipation device includes a base plate and a plurality of fins arranged on the base plate. Each fin includes a fin body including a first metal sheet and a second metal sheet coupled to each other, wherein the fin body is curved and includes a first portion and a second portion transverse to the first portion, an evaporation channel defined in the first portion, one or more connecting channels disposed in the first portion and in fluid communication with the evaporation channel, a condensation channel defined in the second portion, and one or more auxiliary channels disposed in the second portion and in fluid communication with the one or more connecting channels and the condensation channel.

Provided herein is an example heat sink including a heat dissipation unit including a plurality of heat dissipation fin groups including a plurality of heat dissipation fins, the plurality of heat dissipation fin groups forming a laminated structure and a plurality of heat pipes, one end portions of which are thermally connected to a heating element and other end portions of which are inserted into a space provided between the plurality of heat dissipation fin groups forming the laminated structure and thermally connected to the heat dissipation unit.

A temperature plate device includes a plate body and a bent structure. The plate body includes a first plate and a second plate. A chamber is defined by the first plate and the second plate. The first plate has a first step section. The second plate has a second step section corresponding to the first step section. The bent structure is connected to and traverses the first step section between the first step section and the second step section.

Thermal management devices, systems, and methods of fabrication thereof are generally directed to accommodating variability in height, shape, or other geometric features of one or more heat-dissipating components on a substrate while maintaining efficient transfer of heat away from the one or more heat-dissipating components. For example, a thermal management device may include a housing, a diaphragm, and a wick, the wick disposed along a chamber defined by the housing and the diaphragm such that a fluid within the chamber may evaporate and condense along the chamber to transfer heat away from one or more heat-dissipating components (e.g., electronic components or photonics). The diaphragm may be resiliently flexible relative to the housing to bias a contact surface of the diaphragm against one or more heat-dissipating components while maintaining efficient transfer of heat through the chamber and away from the one or more heat-dissipating components.
