摘要: A heat exchanger tube includes protrusions extending into the internal volume to turbulate a fluid flow for improved heat transfer. The protrusions are arranged to provide dimpled and un-dimpled regions in order to provide increased heat transfer together with decreased pressure drop. A method of transferring heat by flowing a fluid into a tube, turbulating the fluid in a dimpled first tube section, developing a thermal boundary layer in an un-dimpled second section, and turbulating the fluid in a dimpled second tube section is also presented.

摘要: A fitting/manifold assembly and method are provided for a heat exchanger. The method includes the steps of providing a manifold (22) including a wall (30) having an aperture (32) therethrough; providing a fitting (24) including a body (42), a nipple (44) extending from the body (42) and having an interior surface (50), and an opening (54) extending through the body (42) to allow access to the interior surface (50); inserting the nipple (44) into the aperture (32) from one side of the wall (30) so that the body (42) of the fitting (24) is on the one side of the wall (30) and a portion (48) of the nipple (44) is on the other side of the wall (30); deforming the interior surface (50) of the nipple (44) with a deforming tool (60, 104) inserted through the opening (54) in the body (42) to enlarge the portion (48) to a shape that restricts retraction of the nipple (44) from the aperture (32).

摘要: A multi-fluid heat exchanger and a method of making the same are provided wherein a cut portion is provided in an elongated header of the heat exchanger at a location between a pair of baffles in the elongated header and first and second cores of the heat exchanger. At least a majority of the transverse cross section of the elongated header is removed at the cut portion to allow for relative thermal growth of the first and second cores.

摘要: Difficulties in brazing or welding a fitting that may be utilized in a heat exchange system are avoided in a construction that includes a mounting block (100) including a formation (102) by which the block (100) may be mounted on another object such as a support (10). At least one aperture (108, 110) extends through the block (100) at a sleeve (112, 114), having opposed ends (122, 128; 158, 160) and an exterior surface (131, 155) sized to snuggly and slidably pass at least partially through the aperture (108, 110) and an interior surface (126, 150) defining a fluid passage. A pair of axially spaced grooves (140, 142; 152, 154) are in the exterior surface (131, 155) and are spaced a distance about equal to the thickness of the block (100) at the apertures (108, 110). A retaining ring (176, 178) may be located in one of the grooves (140, 152) and a retaining clip (170) is removably received in the other groove (142, 154) remote therefrom. As a consequence, the sleeve (112, 114) may be joined to tubing (34, 38) in a heat exchange system without subjecting the mounting block (100) to the bonding procedure.
