Directed decoupling between bundle and core tube in wound heat exchangers
The invention relates to a device (1) for use in the production of a tube bundle (3) of a wound heat exchanger (100), wherein tubes (30) are wound in a plurality of tube layers (4) onto a core tube (300) running in an axial direction (z), webs (10) which run in the axial direction (z) being arranged between the tube layers (4). The invention further relates to a method for producing a tube bundle using said device (1).
HEADER TANK AND CORRESPONDING HEAT EXCHANGER
The invention relates to a header tank (5) for a mechanically assembled heat exchanger, notably for a motor vehicle, said exchanger (1) comprising a mechanically assembled heat-exchange core bundle (3) and comprising at least one row of tubes (31) with two end tubes (31) one at each end of said at least one row, the tubes (31) respectively comprising an end (311) intended to open into an interior volume of the header tank (5). According to the invention, the header tank (5) comprises at least one end stop (55) configured to be positioned facing an internal surface of the end (311) of an associated end tube (31) and to collaborate with said internal surface in such a way as to prevent said tube (31) from moving in the direction of the interior volume of the header tank (5).
PLATE HEAT EXCHANGER
A plate heat exchanger includes a stack of plate pairs with gaps between adjacent pairs, arranged to provide flow paths for a first fluid to pass through inner volumes of the plate pairs while simultaneously allowing a second fluid to flow over the outer surfaces of the plate pairs. At least one cylindrical fluid manifold for the first fluid extends through the plate pairs. A non-planar cap is arranged at one end of the plate heat exchanger to close off the cylindrical fluid manifold. A reinforcement plate is arranged at that end between the non-planar cap and an end plate of the plate heat exchanger. The position of the non-planar cap relative to a central axis of the cylindrical fluid manifold is maintained in order to prevent failure of the plate heat exchanger due to internal pressurization.
RADIATOR AND LATERAL BUMP STOP THEREFOR
A radiator includes a radiator frame, an array of tube assemblies each including a coolant tube and a tube clip supported in the radiator frame, and a lateral bump stop fitted between the array of tube assemblies and the radiator frame. The lateral bump stop includes cushions arranged in a staggered cushion pattern complementary to a staggered packing pattern of the tube assemblies with each of the cushions in contact with the tube clip of one of the tube assemblies.
HEAT EXCHANGER
A bottle for a heat exchanger extending in a longitudinal direction, including a tubular main body comprising a first opening, a plug having a plug body inserted at least partially into the tubular body to close the first opening, a retaining element adapted to retain the plug with respect to the tubular main body after insertion of the retaining element into the tubular main body, wherein the plug comprises a guiding means adapted to guide the retaining element during insertion of the retaining element and the retaining element is configured to be locked in the tubular body, the retaining element and the plug cooperating together to retain the plug in the tubular main body along the longitudinal axis.
Condenser
A condenser includes a housing formed in a hollow shape and having a steam inlet and a condensate outlet, inlet water chambers and outlet water chambers provided at respective ends of the housing. A large number of heat-transfer tubes connect the inlet water chambers and the outlet water chambers to each other inside the housing. Cooling water flows in the heat-transfer tubes, and intake pipes and drainpipes are respectively coupled to the inlet water chambers and outlet water chambers via expansion joints.
Hybrid heat exchanger
In one aspect, a hybrid heat exchanger that includes a metallic serpentine tube having an inlet end portion to receive a process fluid, an outlet end portion, and a series of runs and return bends directing the process fluid from the inlet end portion to the outlet end portion of the metallic serpentine tube. The hybrid heat exchanger further includes a thermally conductive polymer body thermally integrated with the serpentine tube. The thermally conductive polymer body has an outer surface to be contacted by a fluid, such as air and/or water. The thermally conductive polymer body is configured to transfer heat between the metallic serpentine tube and the fluid contacting the outer surface of the thermally conductive polymer body. The outer surface of the thermally conductive polymer body includes surface enhancement features that affect flow of the fluid across the outer surface of the thermally conductive polymer body.
