A fluid control device includes a housing having plural surfaces defining a cavity within the housing. The housing includes an inlet to receive a fluid mixture and an outlet to direct the fluid mixture out of the housing. The fluid mixture includes a fluid combined with debris. A structure array is disposed within the cavity and includes plural structures. Each of the plural structures includes a first surface coupled with an internal surface of the housing and a second surface disposed a distance away from the internal surface of the housing. The structure array includes a first portion and a second portion. The first portion is configured to interfere with the fluid mixture to separate at least some of the debris from the fluid, and the second portion is configured to direct the fluid and at least some of the debris toward the outlet.

A heat exchanger system includes a core-in-shell heat exchanger and a liquid/gas separator. The liquid/gas separator is configured to receive a liquid/gas mixture and to separate the gas from the liquid. The liquid/gas separator is connected to the core-in-shell heat exchanger via a first line for transmitting gas from the liquid/gas separator to a first region in the core-in-shell heat exchanger and connected to the core-in-shell heat exchanger via a second line for transmitting liquid from the liquid/gas separator to a second region of the core-in-shell heat exchanger.

A system and method determine a heat exchanger efficiency of a fluid that flows through a heat exchanger included in a working fluid system. Characteristics of a fluid are monitored in real-time as the fluid flows through the flow path of a heat exchanger. A fluid status is determined in real-time that is associated with a plurality of heat exchange parameters of the fluid as the fluid flows through the flow path of the heat exchanger that is determined from the heat exchanger parameters detected by the fluid monitoring device. A corrective action is determined in real-time when the fluid status of the fluid indicates that the corrective action is to be executed to prevent damage to the working fluid system and an assessment is generated of the corrective action that is to be executed based on the heat exchanger parameters detected by the fluid monitoring device.

A method for manufacturing a roll-bond heat exchanger has steps of: (1) A preparing step: preparing an in-process roll-bond plate that has a main plate with a bulged structure, and a degassing portion with a tube; (2) A degassing step: removing air from the bulged structure through the tube; (3) A filling step: filling refrigerant into the bulged structure; (4) A pressing step: pressing the bulged structure flat to form a pressed portion; (5) A cutting step: cutting the degassing portion to form a cut portion on the main plate; and (6) A sealing step: welding the cut portion. The main plate and the degassing portion are integrally formed as a single part and the degassing portion is able to be directly connected with the vacuum filling machine. Accordingly, processing steps and manpower for manufacturing the roll-bond heat exchanger are reduced.

A heat exchange assembly includes an upper cover panel, a lower cover panel, a plurality of stacked plate assemblies, and a plurality of fins interposed between the plurality of plate assemblies. Each of the plurality of plate assemblies forms a flow passage for receiving a coolant. A continuous flow path extends through the heat exchange assembly. The flow path is in fluid communication with the flow passage of each of the plates and configured to convey air from each of the flow passages to an environment separate from the heat exchanger.

A two-phase immersion cooling device includes a tank, heating elements, a first condenser, and a lid. An accommodating cavity of the tank bottom accommodates a coolant. The heating elements are disposed in the accommodating cavity and immersed in the coolant. The first condenser is received in the accommodating cavity, located above the coolant and the heating elements, and disposed along sidewalls of the tank. At least one movable second condenser is fixed on the lid or a rear door and disposed in a cavity surrounded by the first condenser. The two-phase immersion cooling device increases the capacity of condensation heat transfer, and the condensation rate and the evaporation rate of the coolant in the tank are balanced, a pressure difference between an inside and an outside of the tank is reduced, a loss of coolant vapor is decreased, and a volume of the two-phase immersion cooling device is reduced.

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.

The invention relates to a heat recovery unit to transfer heat from a gray water source discharged from a bath or a shower to preheat fresh cold water supplying a bath, a shower, a boiler system or hot water heater. The heat recovery unit comprises an inner tube, an outer tube, a non-return valve, an anode, deflectors as well as associated piping and fittings. Fresh water from a pressurized public network or well flows through the inner tube while the gray water flows between the inner and outer tubes. The non-return valve installed in the fresh water pipe prevents contamination of the drinking water system. A translucent pipe may be installed in a section of the gray water piping system to detect any leaks. An insulated jacket may be placed around the unit to reduce heat loss. The heat recovery unit may be used in domestic, commercial, industrial and institutional buildings.

A closed-loop system and method for heating of target contaminant zones having environmental contaminants of concern present in the groundwater and the soil by thermal conduction, and subsequent enhancements of physical, biological and chemical processes to attenuate, remove and degrade contaminants in the target contaminant treatment zones, is disclosed. The system and method collects solar or other heat and transfers the heat via a closed-loop and a set of borehole exchangers to subsurface soil in the proximity of and/or directly to the target contaminant treatment zones. The target contaminant treatment zone may comprise contaminated soil, contaminated groundwater in an aquifer, or industrial waste comprising water and/or solids. Solar collectors or heat exchangers capturing waste heat from industrial processes may be used as the heat source.
