A heat exchanger includes tubes arranged side by side, and a tank connected to ends of the tubes. The heat exchanger performs heat exchange between a first fluid flowing inside the tubes and a second fluid flowing outside the tubes. The heat exchanger includes a closing member disposed inside the tank and partially closing an opening provided at an end of a predetermined tube that is at least one of the tubes. The predetermined tube has a protrusion formed at the end of the predetermined tube. The closing member has an avoiding structure that avoids interference between the protrusion and the closing member.

A heat exchanger header includes a first inlet, a first passageway that fluidically connects the first inlet to a first outlet, a second inlet, and a second passageway. The second passageway fluidically connects the second inlet to a second outlet. The first inlet, the first passageway, and the first outlet are fluidically isolated from the second inlet, the second passageway, and the second outlet.

A heat exchanger has: a heat transfer tube group made up of plural heat transfer tubes each of which has, inside the heat transfer tube, a flow passage through which refrigerant flows; a fin provided on the heat transfer tubes; and a bridging header into which end portions of the heat transfer tubes are inserted and that causes refrigerant to flow between the heat transfer tubes. The bridging header has a base having a flat plate shape. The bridging header also has a corrugated sheet forming, between the corrugated sheet and the base, a header flow passage, through which refrigerant flows. The bridging header also has a covering plate covering the corrugated sheet and pressing the corrugated sheet toward the base.

A crimping frame or crimping base for a charge air cooler may include a circumferential raised rim including a plurality of crimping slots. The plurality of crimping slots may each include two longitudinal sides and two narrow sides. The two longitudinal sides may be disposed opposite one another and may extend parallel to the rim. The two narrow sides may be stiffened via a bent reinforcement. The bent reinforcement and the rim may be structured as a single piece.

A collector tube for a heat exchanger, which may have at least one flat tube, may include at least one recess, through which a separator may be inserted into the collector tube in an insertion position. The separator may have a separating wall comprising a separating wall thickness, wherein a clearance fit may be present between the separating wall and the recess in response to the insertion of the separator. The separating wall may provide at least one elevation to attain an increase of the separating wall thickness in a subarea of the separator. In the insertion position of the separator, the at least one elevation may be arranged in an area of the recess. In the insertion position, a press fit may be present between the at least one elevation and the recess.

An apparatus and method of forming a heat exchanger includes forming a monolithic core body having a first set of flow passages and a core coefficient of thermal expansion, and additively manufacturing onto the monolithic core a first manifold defining a first fluid inlet for the first set of flow passages.

An integrally-formed liquid collecting box structure and a method for manufacturing the same are disclosed. The integrally-formed liquid collecting box structure includes an integrally-formed liquid collecting box, a screw, and a leak-proof sealing ring. The leak-proof sealing ring is located between a nut portion of the screw and an inner end face of a stepped hole. The screw is screwed into an internal threaded hole. When the screw is tightened, the nut portion squeezes the leak-proof sealing ring so that the leak-proof sealing ring is deformed and clamped between the nut portion and the inner end face of the stepped hole, so as to prevent leakage.

A heat exchanger includes: a plurality of tubes arranged in an up-down direction; and a reinforcing plate arranged on a lower side of a lowermost tube of the plurality of tubes. The reinforcing plate has a bent portion protruding downward and extending along a longitudinal direction of the tube. The bent portion includes at least one discharge hole to discharge a condensed water. The discharge hole is formed by an upstream rib extending from the upper side toward the discharge hole in an upstream region and a downstream rib extending from the upper side toward the discharge hole in a downstream region, and a height dimension of the upstream rib is different from a height dimension of the downstream rib at least partially along a longitudinal direction of the tube.

The present invention relates to an evaporator of a working fluid for an OTEC plant, comprising an elongated evaporator body extending along a main axis, a bundle of evaporators transporting hot water, a sprinkling system arranged in an upper part of the evaporator body, a system for evacuating the fluid in gaseous state and a guide system for the fluid in gaseous state towards the evacuation system. The guide system comprises an elongated cover extending along the main axis, covering the bundle of evaporators and the sprinkling system, and two partitioning means which are arranged at each end of the evaporator body and form on each of these ends a sealed connection between the outer surface of the cover and the inner surface of the evaporator body.

A heat exchanger includes a tubular refrigerant distributor having insertion holes spaced from each other in a first direction and into which ends of heat transfer tubes are inserted in a second direction. A first partition plate partitions the refrigerant distributor into a first space into which the ends of the heat transfer tubes are inserted and a second space, larger than the first space, into which the ends of the heat transfer tubes are not inserted; and an inflow pipe provided on a one side-surface side of the refrigerant distributor. The heat transfer tubes are located apart from the first partition plate in the first space. The first partition plate is provided with an orifice that is provided at a location corresponding to a space between adjacent ones of the heat transfer tubes, and that causes the first space and the second space to communicate with each other.
