US Patent:

6619380, Sep 16, 2003

Filed:

Apr 23, 2002

Appl. No.:

10/128322

Inventors:

Brian M. Hartman - Lockport NY
Robert Charles Gmerek - Burt NY

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F28F 902

US Classification:

165 71, 165173, 137 6819

Abstract:

A heat exchanger ( ) having a heat exchanger drain assembly ( ) comprising a manifold ( ) for storing fluid. A drain port ( ) is integrally formed with the manifold ( ) and is in selective fluid communication with the reservoir ( ) for selectively draining the fluid from the manifold ( ). A plug ( ) is disposed within the drain port ( ) for preventing fluid from draining from the manifold ( ). The plug ( ) is removable from the drain port (( ) for allowing fluid to drain from the manifold ( ). A frangible wall ( ) is formed between the drain port ( ) and the reservoir ( ) to close the drain port ( ) and create a non-functional drain port ( ), thereby preventing fluid communication between the drain port ( ) and the reservoir ( ). The frangible wall ( ) is fracturable to provide the fluid communication between the drain port ( ) and the reservoir ( ) for draining the fluid from the tank ( ).

Appl. No.:

11/088415

Inventors:

Karl Paul Kroetsch - Williamsville NY, US
Brian M. Hartman - Lockport NY, US
Mark R Hammer - Getzville NY, US

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F28D 1/053

US Classification:

165149, 165153, 165175

Abstract:

A heat exchanger assembly that addresses the thermal cycling problem to increase the durability of the heat exchanger core by fabricating at least the tube next adjacent to each of the reinforcing members with a cross section adjacent each of the headers including a radius having a partial maximum tube strain energy density and fabricating each of the reinforcing members with a connection section adjacent each of the headers having a reinforcement with a partial maximum strain energy density greater than the partial maximum strain energy density of the adjacent tube.
