Publication number: 20240153846Abstract: The present disclosure provides a thermal management device. In some cases, the thermal management device may comprise a first portion of a housing. The first portion may be configured to facilitate a transfer of a first thermal energy from a first surface of an integrated circuit module (ICM) to a surface of the first portion, or vice versa. The thermal management device may further comprise a first plurality of channels disposed within the first portion. The first plurality of channels may be configured to provide a first fluid flow path in thermal contact with the first portion. The first fluid flow path may be configured to facilitate a transfer of the first thermal energy from the first portion to a cooling fluid disposed within the first fluid flow path.Type: ApplicationFiled: August 29, 2023Publication date: May 9, 2024Inventors: Karthik BODLA, Xiangyu GAO, Arian AGHABABAIE, Jonathan POMEROY

Patent number: 11683919Abstract: A heat pipe assembly includes walls having porous wick linings, an insulating layer coupled with at least one of the walls, and an interior chamber sealed by the walls. The linings hold a liquid phase of a working fluid in the interior chamber. The insulating layer is directly against a conductive component of an electromagnetic power conversion device such that heat from the conductive component vaporizes the working fluid in the porous wick lining of the at least one wall and the working fluid condenses at or within the porous wick lining of at least one other wall to cool the conductive component of the electromagnetic power conversion device. The assembly can be placed in direct contact with the device while the device is operating and/or experiencing time-varying magnetic fields that cause the device to operate.Type: GrantFiled: August 11, 2021Date of Patent: June 20, 2023Assignee: General Electric CompanyInventors: Karthik Bodla, Nathaniel Benedict Hawes, Brian Magann Rush, Weijun Yin, Andrew Thomas Cross

Publication number: 20220178626Abstract: The present disclosure provides a thermal management device comprising a vapor chamber, a heat pipe in fluid communication with the vapor chamber, and a fin in thermal contact with the heat pipe. The vapor chamber may contain a first working fluid and may facilitate transfer of thermal energy from a source of thermal energy to the first working fluid. The fin may comprise a fluid flow path configured to direct a second working fluid from a first opening to a second opening. The first opening may be oriented along a first direction of flow towards the fin, and the second opening may be oriented along a second direction different than the first direction. The heat pipe may direct the first working fluid from the vapor chamber through the heat pipe and may facilitate transfer of thermal energy from the first working fluid to the fin or the second working fluid.Type: ApplicationFiled: November 9, 2021Publication date: June 9, 2022Inventors: Arian AGHABABAIE, Brian ADZIMA, Peter SCHMEHL, Daniel CHRISTIANSEN, Harish IRRINKI, Karthik BODLA

Patent number: 11006549Abstract: A cooling assembly includes a body configured to be placed into thermal contact with a heat source and one or more non-planar, hermetic walls disposed within the body. The one or more non-planar hermetic walls extending around, enclosing, and defining a cooling channel configured to carry cooling fluid through the body such that the cooling fluid contacts internal surfaces of the cooling channel inside the body. The assembly including one or more enhancement structures disposed within the body and coupled with the one or more non-planar hermetic walls. The one or more enhancement structures shaped to change a flow path of the cooling fluid as the cooling fluid moves within the cooling channel and shaped to increase a surface area contacted by the cooling fluid within the cooling channel.Type: GrantFiled: February 8, 2019Date of Patent: May 11, 2021Assignee: General Electric CompanyInventors: Brian Magann Rush, Corey Bourassa, Lana Osusky, Karthik Bodla, Hendrik Pieter Jacobus de Bock, Naveenan Thiagarajan
