Filed:
Dec 17, 2003
Appl. No.:
10/738746
Inventors:
John S. Hsu - Oak Ridge TN, US
Donald J. Adams - Knoxville TN, US
Gui-Jia Su - Knoxville TN, US
Laura D. Marlino - Oak Ridge TN, US
Curtis W. Ayers - Kingston TN, US
Chester Coomer - Knoxville TN, US
Assignee:
UT-Battelle, LLC - Oak Ridge TN
International Classification:
H01L023/34
US Classification:
257714, 257716, 257719
Abstract:
A cascaded die mounting device and method using spring contacts for die attachment, with or without metallic bonds between the contacts and the dies, is disclosed. One embodiment is for the direct refrigerant cooling of an inverter/converter carrying higher power levels than most of the low power circuits previously taught, and does not require using a heat sink.

US Patent:
7191605, Mar 20, 2007
Filed:
Nov 21, 2005
Appl. No.:
11/164375
Inventors:
John S. Hsu - Oak Ridge TN, US
Curtis W. Ayers - Kingston TN, US
Chester Coomer - Knoxville TN, US
Laura D. Marlino - Oak Ridge TN, US
Assignee:
UT-Battelle, LLC - Oak Ridge TN
International Classification:
F25B 27/00
US Classification:
62117, 622592, 62505
Abstract:
A method for cooling vehicle components using the vehicle air conditioning system comprising the steps of: tapping the hot liquid refrigerant of said air conditioning system, flooding a heat exchanger in the vehicle component with said hot liquid refrigerant, evaporating said hot liquid refrigerant into hot vapor refrigerant using the heat from said vehicle component, and returning said hot vapor refrigerant to the hot vapor refrigerant line in said vehicle air conditioning system.

US Patent:
20040118144, Jun 24, 2004
Filed:
Nov 18, 2003
Appl. No.:
10/716060
Inventors:
John Hsu - Oak Ridge TN, US
Donald Adams - Knoxville TN, US
Gui-Jia Su - Knoxville TN, US
Laura Marlino - Oak Ridge TN, US
Curtis Ayers - Kingston TN, US

F25D023/12
F25B031/00
US Classification:
062259200, 062505000
Abstract:
This invention presents the device and method for cooling electric machines with hot liquid refrigerant in a floating refrigerant loop and using an internal liquid such as oil for enhancing the cooling effects. The electric machine cooling apparatus has at least one refrigerant tube disposed in the electric machine. The refrigerant tube is in thermal communication with the electric machine. An internal liquid is disposed inside the frame of the electric machine. The internal liquid is in thermal communication with the electric machine and at least one refrigerant tube. The refrigerant is at least partially a hot liquid refrigerant supplied from a floating refrigerant loop.
