A printed circuit-type heat exchanger includes a vaporizer having a structure in which one or more A-channel plates and one or more B-channel plates are sequentially stacked, to vaporize a fluid A with heat exchange through the A-fluid channels. A gas-liquid separator separates the fluid A into a vaporized gas and a non-vaporized liquid and includes a gas outlet for the vaporized gas and a liquid outlet for non-vaporized liquid. A super heater, having the same structure as the vaporizer, super heats the vaporized gas with heat exchange through the A-fluid channels and discharges the superheated gas through a gas outlet communicating with the outside. A first intermediate plate is disposed between the vaporizer and the gas-liquid separator to separate the vaporizer from the gas-liquid separator, and a second intermediate plate is disposed between the gas-liquid separator and the super heater to separate the super heater from the gas-liquid separator.

A fuel cell system includes a gas liquid separator provided downstream of a humidifier in an oxygen-containing gas inlet channel, a fuel exhaust gas inlet channel for guiding a fuel exhaust gas containing liquid water discharged from a fuel cell stack to the gas liquid separator. The gas liquid separator performs gas liquid separation of both of an oxygen-containing gas humidified by the humidifier and the fuel exhaust gas containing the liquid water guided from the fuel exhaust gas inlet channel.

A tamper-proof fluid sediment trap including a central body portion having a central longitudinal axis, an outlet leg portion, a drip leg portion, and a supply leg portion. The outlet leg portion extends upward from the central body portion parallel to the central longitudinal axis and is configured to operably couple to an appliance. The drip leg portion extends downward from the central body portion and defines a shape being resistant to threading or tapping of an outer surface or an inner surface of the drip leg portion. The supply leg portion is configured to couple to a fluid supply line, extends radially outward from the central body portion, between the outlet leg portion and the drip leg portion, and has a central longitudinal axis extending perpendicular to the central longitudinal axis of the central body portion. The portions of the tamper-proof fluid sediment trap are monolithically formed.

A concentrating apparatus for concentrating compressed air includes a first hollow cylindrical concentrating unit which is adapted to cause compressed air to: (i) collide with an upstream side of a collision plate so as to be concentrated and partially liquefied; (ii) move to an annular passage and be jetted into an air moving chamber so as to be adiabatically expanded and partially liquefied; (iii) be compressed in an air compressing passage and pushed out so as to retreat along a conical partition wall; (iv) collide with a downstream side of the collision plate so as to be concentrated and partially liquefied; (v) be introduced into an upstream end of an outlet tube; and (vi) move to a downstream end of the outlet tube and into a second hollow cylindrical concentrating unit.

A filter assembly includes a first screen, defining a first flow passageway, a second screen, defining a second flow passageway, and a third screen defining a third flow passageway. The second screen is positioned between the first screen and the third screen. The first flow passageway is aligned with the third flow passageway and the second flow passageway is offset from the first flow passageway and the third flow passageway.

An air intake device for a vehicle. The device includes an inlet for air, a first outlet arranged for providing air to an engine of the vehicle and a second outlet arranged for discharging liquid separated from the air provided to the first outlet, and an intermediate portion forming an air channel extending from the inlet to the first outlet and the second outlet. A bottom surface on the inside of the intermediate portion is inclined relative to a horizontal plane for directing liquid in the air channel towards the second outlet.

A filter unit (300) includes: a chassis (303) that has a suction portion (301) provided at a front side thereof, has an exhaust portion (302) provided at a rear side thereof, and is provided internally with an upstream filter (331); a plurality of upstream first ribs (323) disposed parallel to sidewalls of the chassis (303) to rise from a bottom surface (322) of the chassis (303) and forming an upstream first airflow path (P11); a plurality of upstream second ribs (313) disposed parallel to the sidewalls of the chassis (303) to rise from a ceiling surface (312) of the chassis (303) and forming an upstream second airflow path (P21); an upstream first shield plate (315) raised from the ceiling surface (312) to cover up a front of the upstream filter (331) while forming an upstream first gap (S11) with the bottom surface (322); and an upstream second shield plate (325) raised from the bottom surface (322) to cover up a rear of the upstream filter (331) while forming an upstream second gap (S21) with the ceiling surface (312).

A gas-liquid separation device comprises: an outer housing extending vertically, which is provided with a gas outlet at an upper end of the outer housing and a liquid outlet at a lower end of the outer housing; an inner housing disposed in the outer housing and extending vertically, an upper end of the inner housing being coupled to the outer housing in a sealed manner, a lower end of the inner housing being opened, with an annular space formed between the outer housing and the inner housing; a feeding tube inserted into the outer housing and communicated with the inner housing, with a cyclone mechanism between the feeding tube and the inner housing to output fluid into the inner housing as a swirling flow. The present disclosure can reduce the disturbance of the downward gas flow and the upward gas flow in the separation space, thus improving the separation efficiency.
