Filed:

Aug 23, 2011

Appl. No.:

13/215333

Inventors:

Harald Schatz - Reutlingen, DE

Daniel E. Hornback - Davisburg MI, US
Andrew Boyer - Cudahy WI, US

International Classification:

F28D 7/00

US Classification:

165157

Abstract:

An exhaust gas heat exchanger that includes a stack at least partially surrounded by a housing. The stack includes a first tube, a second tube, and a coolant duct between the first tube and the second tube. A fin is located within the coolant duct. The fin includes a first portion and a second portion and the first tube includes a first portion and a second portion. The first portion of the fin is fixed to the first portion of the first tube such that the first portion of the fin is coupled to the first portion of the first tube for movement with respect to the housing, and the second portion of the fin is supported in the housing for movement relative to the second portion of the first tube to permit movement of the second portion of the first tube with respect to the second portion of the fin.

Feb 10, 1997

Appl. No.:

8/799023

Inventors:

Andrew D. Boyer - Denver PA

Assignee:

Crompton & Knowles Corporation - Stamford CT

International Classification:

D06P 1382
C09B 62503

US Classification:

8549

Abstract:

An aqueous reactive dye composition is disclosed. The aqueous reactive dye composition has improved storage stability and contains a water-soluble reactive dye and a chelating agent. The chelating agent is present in a sufficient concentration to maintain the pH of the aqueous reactive dye composition in the range of about 3. 0 to about 7. 0 and, preferably, about 5. 0 to about 6. 5. Desirable chelating agents are dicarboxylic acids, such as succinic acid, or amino carboxylates, such as nitrilotriacetic acid. A method of stabilizing an aqueous reactive dye composition is disclosed and includes the step of dissolving a polycarboxylic acid or an amino carboxylate in an aqueous solution of a water-soluble reactive dye in a sufficient concentration to stabilize the pH of the composition.

International Classification:

F28D 9/00
F28F 27/00
F28F 9/02

Abstract:

A heat exchange system and apparatus for a vehicle powertrain configured to exchange heat between a first fluid and a second fluid within a heat exchanger core formed by a plurality of stacked plates having separate channels for the first fluid and the second fluid. The heat exchanger system includes multiple heat exchangers, one of which is connected to a both the inlet and the outlet of a vehicle powertrain component, another of which is fluidly connected or at least partially disconnected from the vehicle component according to the mode of operation of the heat exchange system. The heat exchanger connected to the vehicle component includes a jumper tube to return the first fluid to the vehicle component through a core of the heat exchanger.

F01P 7/16
F16H 57/04
F28F 27/02

Abstract:

A thermal management unit for a vehicle powertrain includes an integrated oil heater, a control valve, and a pressure relief valve. A remote oil cooler is connected to fluid ports of the thermal management unit. Transmission oil is received into the thermal management unit and is directed to one or both of the transmission oil heater and the transmission oil cooler. A portion of the flow of oil can be internally bypassed through the pressure relief valve to maintain the pressure of the oil below a threshold. The flow of oil is directed through the control valve after having been heated and/or cooled, and the proportions of oil being directed through the oil heater and the oil cooler are determined by the temperature of the oil in the control valve.
