A heat exchanger for severe temperature and fluid flow conditions in one configuration includes a first longitudinal shell, a second longitudinal shell, and a transverse shell extending transversely between the longitudinal shells. The longitudinal shells may be parallel to each other. The shells are fluidly coupled directly together to form a common shell-side space between an inlet and outlet tubesheet. A generally U-shaped assembly of shells is thus formed. The tube bundle has a complementary U-shaped configuration comprising a plurality of tubes which extend through the longitudinal and transverse shells between the tubesheets. An expansion joint fluidly couples each longitudinal shell to one of the tubesheets. The shell-side inlet and outlet nozzle may be fluidly coupled to the expansion joints for introducing and extracting the shell-side fluid from the heat exchanger. In another configuration, the heat exchanger may be L-shaped with tube bundle of the same configuration.

A heat exchanger assembly including an elongated tubular heat exchanger enclosure defining an interior chamber. A tube sheet is positioned within the interior chamber of the heat exchanger enclosure separating the interior chamber into a shell side and a channel side. The interior portion is configured to removably receive a tube bundle positioned within the shell side of the interior chamber. An annular sleeve member is positioned within the channel side of the interior chamber of the heat exchanger enclosure. An annular elastic torsion member is positioned within the channel side of the interior chamber of the heat exchanger such that the sleeve member is positioned between the tube sheet and the elastic torsion member. The elastic torsion member has an inner circumference deflectable relative to its outer circumference for torsioning the elastic torsion member.

A pressure control system for a liquid-cooled electronic component cooling device. A cooling device cools an electronic component through a refrigerant moving along a pipe. A radiator is mounted on one side of the cooling device to exchange heat with the refrigerant, and has a vent hole extending outwardly. A head has discharge holes communicating with a plurality of first hollows formed therein in an outer circumferential surface thereof with a driver hole provided in an upper surface thereof. A body is coupled to a bottom side of the head and has a second hollow communicating with the first hollows in a lengthwise direction. A pressure controller extends outward from a bottom of the body with an inner portion thereof communicating with the second hollow, and includes a coupler having threads on one side of an outer circumferential surface thereof to be screwed into the vent hole.

A heat exchanger for a gas turbine engine includes a core configured to heat or cool a fluid flowing therethrough. The core, in turn, extends along a lateral direction between a first end of the core and a second end of the core and the core defining one or more fluid passages. Furthermore, the heat exchanger includes a manifold coupled to the first end or the second end of the core. The manifold, in turn, includes a manifold wall at least partially defining a fluid chamber in fluid communication with the one or more fluid passages. Moreover, the manifold further includes a feature permitting thermal expansion or thermal contraction of the manifold wall relative to the heat exchanger core.

Provided is a heat exchanger, including: a refrigerant distributor including: a gas-liquid separating portion having a function of separating a gas-liquid refrigerant mixture into a liquid refrigerant and a gas refrigerant; and a distributing portion provided to the gas-liquid separating portion. A plurality of heat transfer pipes connected to the distributing portion. The plurality of heat transfer pipes are arranged side by side in a first direction, and extend along a second direction intersecting with the first direction. When the refrigerant distributor is viewed along a direction orthogonal to each of the first direction and the second direction, a first space forming portion overlaps a region of the plurality of heat transfer pipes. When the refrigerant distributor and the heat transfer pipes are viewed along the first direction, a clearance is present between the gas-liquid separating portion and the heat transfer pipes.

The present invention relates to a heat exchanger and, more specifically, to a heat exchanger, which has a manifold coupled to a header tank, allowing easy attachment between a manifold and a header tank as well as avoidance of interference between the manifold and a support by forming a baffle-shaped fixed baffle on one length direction of the header tank to which the manifold is inserted and attached.

A cabin condenser for a heating, ventilation, and air conditioning (HVAC) system for a battery electric vehicle (BEV). The cabin condenser includes a first cabin condenser portion and a second cabin condenser portion. A regulator is configured to control flow of refrigerant from the first cabin condenser portion to the second cabin condenser portion.

A fluid coil includes a tube bundle having a series of straight tubing runs and a series of return bends extending between and fluidically connecting ones of the straight tubing runs, an expansion header fluidically connected to at least some of the return bends and a polymeric material disposed in the expansion header. The polymeric material has an initial shape and is compressible to repeatedly expand and contract between a first volume in which water is present in the tube bundle and a second volume in which the water undergoes a phase change. Contraction of the polymeric material absorbs an increase in volume as the water undergoes the phase change to prevent stressing and rupture of the tube bundle and upon an opposite phase change, the polymeric material returns to its initial shape. The polymeric material can be a pressurizable bladder. A system and method to prevent the rupture of a tube bundle in a fluid coil are also disclosed.
