A header for a heat exchanger and method for cleaning a heat exchanger in a loop without disconnecting loop components is provided. The header is in flow communication with the heat exchanger for distributing fluid through a plurality of adjacent channels. The header is connected between a main heat exchanger inlet nozzle and a channel flow distributor. A filter element is disposed within the header between the nozzle and channel flow distributor. Under normal operation, the filter element removes particulates and fouling material from the main flow stream before it enters the heat exchanger channels. During the cleaning process, fluid is injected on or through the filter element to remove particulates and fouling material through at least one outlet port. The header arrangement allows the filter element to be 'cleaned in place' without draining the system and disconnecting the heat exchanger or other components from the flow loop.

Flow assisted anti-fouling geometries for compact heat exchangers

The casting material may be formed around the casting core using a variety of conventional casting techniques including direct liquid metal infiltration, pressure assisted casting, and centrifugal casting among others.

Frangible-soluble casting cores and methods of making the same

A heat exchanger includes an inlet for receiving bulk solids, a plurality of heat transfer plate assemblies, a plurality of spacers disposed between adjacent heat transfer plate assemblies, and supports for supporting the heat transfer plate assemblies. The heat transfer plate assemblies include a first plate having a first pair of holes extending therethrough, the first plate having channels extending along a surface thereof, for the flow of fluid through the channels, and a second plate bonded to the first plate to enclose the channels, the second plate including a second pair of holes generally aligned with the first pair of holes to form through holes to facilitate flow of the fluid through the through holes and the channels.

Plate heat exchanger for heating or cooling bulk solids

Hybrid additive featured plates used to form an overall microchannel heat exchanger and corresponding method of manufacture are disclosed. Various additive manufacturing (AM) techniques may be used to form walls defining microchannel features on a plate substrate. The manufacturing method is a hybrid process in that leverages both additive and conventional manufacturing techniques to minimize both cost and fabrication time.

Additively featured plates for heat exchangers

The present disclosure is directed to systems and methods that transfer heat directly from hot particles to a cold fluid, such as sCO, by bringing the hot particles and cold fluid into direct contact at the operating pressure of the cold fluid. These systems and methods can both stand-off large pressure differentials while allowing particles to pass through and limiting cold fluid leakage either continuously or through a batch process.

Direct contact particle-fluid heat exchanger

Systems and methods for cooling a power generation working fluid are disclosed that reduce the amount of cooling fluid used. These systems and methods save on water usage in the generation of power by thermoelectric power generation systems.

Cooling systems and methods for thermoelectric power generation

The present disclosure is directed to systems, devices and methods for cooling a surface with a plurality of ejectors. The fluid provided to the micro-ejectors includes vapor formed at the surface. The vapor provides the driving force for driving fluid through the micro-ejectors.
