A heat exchange tube (51) for a heat exchanger, heat exchanger and assembly method thereof. The heat exchange tube (51) is a combined heat exchange tube having a space (55) at its center, and the space (55) is configured to accommodate an insertion member (57), such that the combined heat exchange tube is expanded in and joined with a corresponding fin hole (53) in the heat exchanger. A heat exchange tube that is minute or has a small inner diameter can thus be expanded in a heat exchanger fin without employing a brazing process.

A heat exchanger includes a tank, multiple tubes, a tube support member that supports the multiple tubes, and a shell body joined to the tube support member. The tube support member is cylindrical and includes a first-end cylindrical portion, a second-end cylindrical portion, and an intermediate cylindrical portion having a diameter smaller than that of the first-end cylindrical portion and having a predetermined length in an axial direction between the first-end cylindrical portion and the second-end cylindrical portion. The tank and the first-end cylindrical portion are welded to each other. The shell body and the second-end cylindrical portion are brazed to each other. Outer peripheral portions of the tubes are in contact with and brazed to an inner surface of the intermediate cylindrical portion.

Cleanout systems are disclosed. An example environmental control system includes an exhaust plenum to exhaust cooling fluid from a heat exchanger outlet of a heat exchanger, and a cleanout system coupled to the exhaust plenum adjacent the heat exchanger outlet. The cleanout system includes a cleanout passageway to fluidly couple a cleanout inlet accessible from an outer surface of the exhaust plenum and a cleanout outlet in fluid communication with the heat exchanger outlet. The cleanout system is to enable removal of particulate from the heat exchanger without disassembling the heat exchanger from the exhaust plenum or an air intake.

A heat exchanger tube includes a central tube portion having a C-shape cross-section. A pair of tube ends includes the C-shape cross-section or a different cross-section. A heat exchanger tube assembly and a method for manufacturing a C-shape heat exchanger tube are also described.

Provided is a heat exchanger. The heat exchanger includes: a core portion configured to have a cooling water channel provided therein; a housing configured to have a concave shape to have the core portion inserted thereinto so that the core portion is housed therein and have one side provided with an air inlet into which air is introduced and the other side provided with an air outlet through which the air is discharged; and a sealing member configured to be interposed between an outer side of the core portion and an inner side of the housing to seal between the core portion and the housing, thereby preventing air from being bypassed between the core portion and the housing to improve heat exchange efficiency and heat exchange performance.

Each of a first outside plate and a second outside plate includes bent portions at its both ends in a direction perpendicular to a direction in which a low-temperature fluid flows. The bent portions of the first outside plate and the bent portions of the second outside plate are respectively welded together in a resiliently deformed state to approach each other. The bent portions of the first outside plate and the bent portions of the second outside plate are respectively welded together to generate stress to press a first power generation module and a second power generation module on a duct.

The present disclosure relates to a heat exchanger, for example an indirect charge air cooler for an internal combustion engine. The heat exchanger includes a heat exchanger block including a first channel system for a first fluid and a second channel system for a second fluid that is fluidically separate from the first channel system. Two opposite side parts and two opposite end parts are structured and arranged to fluidically delimit the second channel system. At least one frame part is connected with a respective edge of the two side parts and of the two end parts. An air inlet box is connected to the at least one frame part via a seal. The heat exchanger block has a width b1 and a height h1, and the seal has a width b.sub.2 and a height h.sub.2, where b.sub.1b.sub.2 and h.sub.1h.sub.2.

The present invention relates to a device for managing gases suitable for being installed at the outlet of a particle filter or a catalytic converter. This device is characterized by a very compact configuration combining at least the heat exchanger for an EGR (Exhaust Gas Recirculation) system, particularly suitable for a low-pressure system, and an exhaust gas outlet pipe with a special configuration that is part of the exhaust line. The exhaust outlet incorporates a valve that allows using the heat exchanger of the EGR system as a heat recovery unit.

A system and method for thermally exchanging heat between waste air being expelled from a poultry barn and fresh outside/outdoor ambient air being introduced into the poultry barn.

A heat exchanger manufacturing method comprising: a welding step of disposing a first weld bead through a thickness of one of the inner and outer plate portions and fusing the first weld bead to other of the inner and outer plate portions for joining together the first and second case halves, to thereby provide the heat exchange tube; and a temporary tacking step of providing a temporarily-assembled end plate/tube unit by temporarily tacking the heat exchange tube to each of the end plates by means of a second weld bead and filling, with the second weld bead, a gap of a generally triangular shape defined, at each of the opposite end portions of the heat exchange tube, by an outer surface of the inner plate portion, an end surface of the outer plate portion and a corresponding one of the end plates.
