International Classification:

F28F 1312

US Classification:

1651091, 165166, 165916

Abstract:

A turbulator ( A- K) is provided for use in the heat exchange units ( ) of heat exchangers. The turbulator ( A- K) includes a sheet ( A, C) of material. The sheet ( A, C) includes a plurality of strand-like rows ( A, C) of alternating crests ( A, C) and valleys ( A, C). The crests ( A, C) and valleys ( A, C) in each row ( A, C) are offset with respect to the crests ( A, C) and valleys ( A, C) in any immediately adjacent row ( A, C). Each of the rows ( A, C) has an interface with any immediately adjacent row ( A, C). The interfaces are perforated so that valleys ( A, C) in each row ( A, C) are in fluid communication with immediately adjacent crests ( A, C) in any immediately adjacent row ( A, C) and crests ( A, C) in each row ( A, C) are in fluid communication with any immediately adjacent valleys ( A, C) in any immediately adjacent row ( A, C). In some preferred embodiments ( A, C, D, E, F, H, J, K), the plurality of rows ( A, C) are divided into at least two groups ( A, C, J; A, C, J) which together define a herringbone pattern of the crests ( A, C) and valleys ( A, C).

International Classification:

F28F 19/00

US Classification:

165119000

Abstract:

An oil cooler with a integral filter includes first and second elongated tubular headers () in spaced parallel relation together with tube slots in each of the headers with the tube slots facing at an alignment with one another. Elongated flattened tubes () have their ends in aligned ones of the tube slots and are sealed thereto. Fins () extend between the tubes () in thermal conducting relation therewith. A filter housing () is mounted on the oil cooler and an oil filter element () is located within the housing ().

Modine Manufacturing Company - Racine WI

International Classification:

F28F 308

US Classification:

165 51

Abstract:

External conduits for connection to a source of coolant for a donut oil cooler are eliminated in an oil cooler construction including a housing (32) having a base (64). Spaced coolant ports (96,98) are located in the base (64) and a filter mounting surface (68,82) is located on the housing (32) in spaced relation to the base (64). A heat exchange stack (34) is located within the housing (32) and has an oil inlet port (72) in the base (64) and an oil outlet port (76) in the filter mounting surface (68,82). A passage (50) extends through the housing (32) from the base (64) to the surface (68,82).

Assignee:

Modine Manufacturing Company, Inc. - Racine WI

International Classification:

F28F 308

US Classification:

165167

Abstract:

Areas of potential oil stagnation in a donut oil cooler that lower heat transfer efficiency are avoided by locating closed fluid flow passages (100) for unfiltered oil to be directed to a filter (14) within spacers (102), (110), (130), and defined by corresponding apertures (88), (90), (92), (94) in plates (78) and (80) forming oil cooling chambers (76) and located centrally thereof.
