A charge-air cooler includes an airflow path, a heat exchanger in fluid communication with the airflow path, a water reservoir, and a water-wicking plate. The water-wicking plate has a lower portion disposed in the water reservoir and an upper portion disposed in the airflow path, wherein the water-wicking plate includes a water-absorbent material configured to draw water from the water reservoir and to release the water to the airflow path.

A body of heat transfer fluid circulates in a first loop through an indirect screw-type thermal processor, a rundown tank, a pump, a heater and a fill tank, continuously heating the processor. With the pump operating, a first vertical distance between the fill tank bottom and the processor under the influence of gravity sets a minimum fluid pressure at the processor; a stem pipe opening in the fill tank at a second vertical distance above the processor sets a maximum pressure. With the pump inactive, the entire body of fluid passively drains to the rundown tank. Supplying the fluid may entail melting a salt, hydrating a salt, or both; such may be done in the rundown tank before circulation through the processor begins. A hydrated salt may be circulated, then heated and dehydrated, to gradually warm the processor. A dehydrated salt may be rehydrated and then stored; this may be done in the rundown tank after ceasing circulation through the processor. Also described: misting hydration and variable-speed-pump pressure regulation.

A combination refrigeration displacement and drain device is disclosed that can be mounted within a heat exchanger, such as a shell and tube heat exchanger, which may be used for example as a heat exchanger in a chiller unit, which may be used in an HVAC or refrigeration system. One example of such components can include heat exchangers, such as for example a condenser employing a gravity drain. Advantageously, the combination refrigeration displacement and drain device herein can provide a refrigerant charge reduction for example that is used in the chiller unit, while facilitating drainage out of the heat exchanger. The combination refrigeration displacement and drain device can alleviate the liquid refrigerant accumulation that may normally be necessary to induce flow in a gravity drain design.

A radiator assembly for a machine is provided. The radiator assembly includes an inlet tank adapted to receive a coolant. The radiator assembly includes a fluid line having a first end fluidly coupled to the inlet tank. The fluid line is adapted to allow passage of the coolant therethrough. The radiator assembly also includes an outlet tank fluidly coupled to a second end of the fluid line. The outlet tank is adapted to receive the coolant from the fluid line. The radiator assembly further includes a pressure compensating device fluidly coupled to at least one of the inlet tank and the outlet tank.

The invention relates to an indirect-type air cooler by way of which compressed charge air for an internal-combustion engine is cooled by means of a liquid, wherein the air cooler is constructed from stacked pairs of plates having fins which are disposed therebetween, and the brazed stack is disposed in a housing into which the charge air flows, flows through the fins and exits the housing again. The charge air exchanges heat with the liquid which flows in the plate pairs and which is introducible into the plate pairs via at least one inlet and via inlet-side plate openings which are flush in the stack and is dischargeable via at least one outlet by means of flush outlet-side plate openings. In order to further improve the performance potential of the air cooler, at least one venting element which extends to the exterior through an opening of the housing is connected to a liquid space within the stack.

A self cleaning filtering method and apparatus for a plate heat exchanger including: a suction pipe, centrally disposed within an inlet channel adapted for receiving a cooling medium therein for the plate heat exchanger; nozzles extending radially from, and in fluid communication with, the suction pipe, the nozzles spaced apart from each other; a low pressure chamber, external to the heat exchanger, abutting the pressure plate, the low pressure chamber in fluid communication with the inlet channel, and a section of the suction pipe extending into the low pressure chamber; a drain valve adapted to reversibly open a drain of the low pressure chamber; and a rotation mechanism controlling axial rotation of the suction pipe.

A heat exchange device and a refrigerant circulation system are disclosed. The heat exchange device includes a housing, defining a first air inlet and a first air outlet; wherein the first air inlet and the first air outlet are spaced apart along a first direction; and a first heat exchange component, arranged in the housing and comprising a plurality of heat exchange fins spaced apart along a second direction; wherein the first heat exchange component is arranged opposite to the first air inlet along a third direction; the second direction is perpendicular to the first direction, and the third direction is perpendicular to the first direction and the second direction.

Two or more cores (2a, 2b) in each of which two more types of passage layers through which two or more fluids flow are layered alternately are welded together. The entire bottom portions of the cores (2a, 2b) are covered with a lower header tank (3), thereby making the fluids flow into the cores (2a, 2b). A dummy layer (14) through which none of the fluids flow is provided beside a weld side face of each core (2a, 2b). A weld spacer (18) is welded to the entire peripheral edge of a side plate (16) of the dummy layer (14). A through-hole (16a) for draining water in the dummy layer (14) is made near the lower end of the side plate of the dummy layer (14). Further, a liquid drain hole (20) through which water is drained is made at a lower corner of the weld spacer (18).

A laminated fluid warmer includes: a laminate including a target fluid layer having a plurality of target fluid channels through which a warming target fluid flows, and a warming fluid layer that is laminated on the target fluid layer and has a plurality of warming fluid channels through which a warming fluid for warming the target fluid layer flows; and a collection device that collects at least a part of the warming fluid accumulated in the plurality of warming fluid channels. The collection device includes a storage portion that receives the warming fluid flowing out from the warming fluid channel when collecting the warming fluid.
