The present invention relates to a heat exchanger for a motor vehicle, including a plurality of plates, the plates being stacked on top of one another along a stacking axis so as to form a bundle of plates, at least a first plate and at least a second plate which define a first circulation path configured for circulation of a first fluid, at least the second plate and at least a third plate which define a second circulation path configured for circulation of a second fluid, the bundle of plates having a first distribution chamber which supplies the first circulation path with first fluid, and a second distribution chamber which supplies the second circulation path with second fluid. The heat exchanger includes at least one purification device arranged in one of the distribution chambers.

A piping system of a steam turbine plant is provided with: steam piping connected to a steam turbine; bypass piping which branches from the steam piping at a branching portion and which is connected to a condenser; a steam check valve provided between the branching portion of the steam piping and the steam turbine; and a turbine bypass valve provided in the bypass piping. A piping system cleaning method includes the steps of: connecting at least one valve of the steam check valve and the turbine bypass valve and a connecting portion provided between the turbine bypass valve of the bypass piping and the condenser, by using temporary piping having a foreign matter collecting portion; closing a flow path on the outlet side of the valve; cleaning the steam piping by supplying steam to the steam piping; and sending the steam to the condenser through the temporary piping.

A magnetic filter 10 includes first and second separation chambers 10, 12. The separation chambers 10, 12 each have an inlet and an outlet, and the separation chambers 10, 12 are joined together such that the inlets of the first and second chambers are adjacent, and the outlets of the first and second chambers are adjacent. An inlet port arrangement 28 connects both inlets to a single inlet pipe, and an outlet port arrangement 30 connects both outlets to a single outlet pipe.

A thermal management system and method for a fuel cell vehicle is provided. In particular, a radiator, a 3-way valve, a pump, a heater, and a stack are all connected in that order. The system is capable of selectively de-mineralizing and providing an increase in flow rate by connecting a de-mineralizer line to a port at a bypass line side of a 3-way valve.

Clean condensate production may be produced from humidity in unfiltered air for an extended period of time using a membrane microgravity air conditioner which comprises an air box, comprising an inlet air flow path from a side face through an open top, and a filtering system disposed within the air box. The filtering system comprises one or more trash screens disposed in the inlet air flow path, one or more latent heat exchangers (LHX) disposed in the inlet air flow path, one or more particulate filters disposed in the inlet air flow path intermediate the trash screen and the LHX, one or more thermal control system (TCS) medium temperature loops, and one or more sensible heat exchangers (SHX) disposed in the inlet air flow path intermediate the particulate filter and the LHX.

A contamination barrier for protecting heat exchanger units, for example, condensers of heating, ventilation, and air conditioning (HVAC) systems. The contamination barrier includes a filtration media which allows particles small enough to pass through a condenser assembly to pass through the contamination barrier, while preventing larger particles from passing therethrough. The contamination barrier inhibits the buildup of debris and other contamination within the condenser assembly while reducing or eliminating the need to clean the barrier, and without significantly reducing airflow through the condenser assembly, thereby promoting the ability of the condenser assembly to maintain operational efficiency. The contamination barrier is adaptable to be applied to a variety of heat exchanger units.

A packing module includes first and second flow paths which exchange heat between water sprayed from above and air flowing from below; a first import portion for importing water sprayed from one side of the packing module into the first flow path; a second import portion for importing water sprayed from the other side of the packing module into the second flow path; a first export portion for guiding water flowing out from the first water path to one side of the packing module for discharging; and, a second export portion for guiding water flowing out from the second water path to the other side of the packing module for discharging. Two flow paths in the packing module operate in different operation modes, so that water or wind flows through one flow path to cool water while air flows through the other flow path for heat exchange through partition walls.

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.
