Patent number: 8516699Abstract: A heat exchanger for transferring heat between a first working fluid and a second working fluid, including a pair of spaced apart headers, a number of tubes extending between the pair of headers and providing a flow path for the first working fluid and being positioned along a flow path for the second working fluid, and an insert supportable in one of the tubes and having a fold extending in a direction substantially parallel to the flow path for the first working fluid through the tubes. The fold can define first and second legs of the insert. A dimple can be formed on the first leg and a protrusion can be formed on the second leg opposite to the dimple on the first leg.Type: GrantFiled: November 22, 2011Date of Patent: August 27, 2013Assignee: Modine Manufacturing CompanyInventors: Frank M.

Patent number: 8261816Abstract: A heat exchanger with a plurality of stacked flat tubes and a collecting tank having a wall extending around the entire periphery of, and connected to, the end of the stacked flat tubes. A first medium may be distributed through the collecting tank and flat tubes. Internal inserts are in the flat tubes, with the inserts being bonded between the broad sides of the tubes and, in the region of connection of the tubes to the collecting tank, being configured to compensate for length changes in the stacking direction caused by temperature changes, as by recesses in connectors such as wave flanks or by corrugated wave flanks. The flat tubes with inserts such as described may be separately provided for use in manufacture of heat exchangers.Type: GrantFiled: December 17, 2004Date of Patent: September 11, 2012Assignee: Modine Manufacturing CompanyInventors: Peter Ambros, Jörg Soldner, Roland Strähle, Andreas Stolz, Dieter Merz, Jens Nies, Sven Thumm, Katja Müller, Harald Schatz, Peter C.

Patent number: 6675878Abstract: A turbulator (60A-60K) is provided for use in the heat exchange units (34) of heat exchangers. The turbulator (60A-60K) includes a sheet (62A, 62C) of material. The sheet (62A, 62C) includes a plurality of strand-like rows (64A, 64C) of alternating crests (66A, 66C) and valleys (68A, 68C). The crests (66A, 66C) and valleys (68A, 68C) in each row (64A, 64C) are offset with respect to the crests (66A, 66C) and valleys (68A, 68C) in any immediately adjacent row (64A, 64C). Each of the rows (64A, 64C) has an interface with any immediately adjacent row (64A, 64C). The interfaces are perforated so that valleys (68A, 68C) in each row (64A, 64C) are in fluid communication with immediately adjacent crests (66A, 66C) in any immediately adjacent row (64A, 64C) and crests (66A, 66C) in each row (64A, 64C) are in fluid communication with any immediately adjacent valleys (68A, 68C) in any immediately adjacent row (64A, 62C).Type: GrantFiled: December 9, 2002Date of Patent: January 13, 2004Assignee: Modine Manufacturing CompanyInventors: James T.

Patent number: 6590770Abstract: A serpentine, slit fin (26) is provided for a heat sink device (10) used for cooling a electronic component (12) having a surface (14) that rejects heat. The heat sink (10) includes a plate (16) having first and second surfaces (18, 20), with the first surface (18) configured to receive heat from the surface (14) of the electronic component (12). The fin (26) is bonded to the second surface and includes a plurality of offset sidewall portions (48). In one form, a fan (22) is spaced above the second surface (20) to direct an impingement airflow (24) towards the second surface (20) substantially perpendicular to the second surface (20), and the serpentine, slit fin (26) underlies the fan (22) and is bonded to the second surface (20).Type: GrantFiled: March 14, 2002Date of Patent: July 8, 2003Assignee: Modine Manufacturing CompanyInventors: C. James Rogers, Gregory G. Hughes, L. Winston Zhang, Frank M. Grippe, Rifaquat Cheema

Publication number: 20030106677Abstract: The efficiency of a heat exchanger used in applications where heat conduction between rows of conduits located from front to back of the heat exchanger and provided with common fins (42) is increased where the fins (42) are abutted to adjacent tube runs (22,24,26) in each row and extend from the front (28) to the back (30) of the heat exchanger so each fin (42) is common to each of the rows (22,24,26). Heat flow interrupters (56,58) are located in each fin (42) at locations aligned with spaces (27) between the runs (22,24,26). Each heat flow interrupter (56,58) is defined by a slit (62) extending completely through the fin 42 which is characterized by the absence of the removal of any material of which the fin (42) is made at the slit (62).Type: ApplicationFiled: December 12, 2001Publication date: June 12, 2003Inventors: Stephen Memory, C. James Rogers, Gregory G. Hughes, Frank M. Grippe, Rif Cheema, William Markusen, Kenneth Ritt

Each of the rows (64A, 64C) has an interface with any immediately adjacent row (64A, 64C). The interfaces are perforated so that valleys (68A, 68C) in each row (64A, 64C) are in fluid communication with immediately adjacent crests (66A, 66C) in any immediately adjacent row (64A, 64C) and crests (66A, 66C) in each row (64A, 64C) are in fluid communication with any immediately adjacent valleys (68A, 68C) in any immediately adjacent row (64A, 62C).Type: ApplicationFiled: December 9, 2002Publication date: June 12, 2003Applicant: Modine Manufacturing Company.Inventors: James T.

Publication number: 20030102113Abstract: A heat exchanger (10) preferably provides supercritical cooling to the refrigerant of a transcritical cooling system (12). The heat exchanger (10) includes a pair of elongated headers (20, 22) having longitudinal axes (24, 26) disposed substantially parallel to each other, a plurality of elongated tubes (28) spaced in side-by-side relation along the longitudinal axes (24, 26) of the headers (20, 22), and serpentine fins (30) extending between adjacent pairs of the tubes. Each of the tubes (28) has a first end (31) connected to the header (20) and a second end (32) connected to the other header (22) to the headers (20, 22).Type: ApplicationFiled: November 30, 2001Publication date: June 5, 2003Inventors: Stephen Memory, C.

Patent number: 6032503Abstract: A method and apparatus are provided for roll forming a plurality of fin strips (10) from a single elongated strip of sheet material (20). The strip (20) includes a pair of adjacent, longitudinal rows (22, 24) of alternating crests (26) and valleys (28), with the crests (26) and valleys (28) of the row (22) longitudinally offset from the crests (26) and valleys (28) of the other row (24) so that the two rows (22, 24) are joined by a plurality of longitudinally spaced discrete connections (30) that define a longitudinal interface (32) between the two rows (22, 24). The connections (30) are broken by displacing the two rows (22, 24) relative to each other to form a pair of fin strips (36, 38), with each fin strip (36, 38) having a side edge (40, 42) defined by the now separated interface (32).Type: GrantFiled: November 23, 1998Date of Patent: March 7, 2000Assignee: Modine Manufacturing CompanyInventor: Frank M.
