Patent number: 9484283Abstract: Modular cooling apparatuses are disclosed. In one embodiment, a cooling apparatus includes an inlet manifold, a jet plate manifold, a plurality of jet plates, a vapor manifold, and a target layer. The inlet manifold includes a fluid distribution chamber, and a plurality of fluid distribution channels symmetrically located within the fluid distribution chamber. The jet plate manifold is coupled to the inlet manifold such that the plurality of jet plate openings is vertically aligned with respect to the plurality of fluid distribution channels. The plurality of jet plates is removably disposed in the jet plate manifold. The vapor manifold has a plurality of walls that define a vapor manifold opening and at least one outlet channel through at least one of the walls. The target layer is coupled to the vapor manifold such that the jet orifice surface of each jet plate is positioned above the target layer.Type: GrantFiled: January 4, 2013Date of Patent: November 1, 2016Assignee: Toyota Motor Engineering & Manufacturing North America Inc.Inventors: Shailesh N. Joshi, Ercan Mehmet Dede, Matthew Joseph Rau, Mayur Prakash Gaikwad, Suresh V. Garimella

Patent number: 9460985Abstract: Jet-impingement, two-phase cooling apparatuses having alternating vapor outlet channels are disclosed. In one embodiment, a cooling apparatus includes a fluid inlet channel, a jet orifice surface, and a target surface. The jet orifice surface includes an array of jet orifices. The jet orifices are arranged in rows. Coolant fluid within the fluid inlet channel flows through the array of jet orifices as impingement jets. The jet orifice surface further includes a plurality of vapor guide channels positioned between the plurality of jet orifice rows and parallel to a first axis such that the jet orifice surface is defined by alternating jet orifice rows and vapor guide channels. The target surface has a plurality of surface fins extending from a surface of the target surface and parallel to a second axis that is orthogonal to the first axis, wherein the jet orifice surface is positioned proximate the surface fins.Type: GrantFiled: January 4, 2013Date of Patent: October 4, 2016Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Shailesh N.

Patent number: 9099295Abstract: Jet impingement and two-phase cooling apparatuses with sloped vapor outlet channels are disclosed. In one embodiment, a cooling apparatus includes a fluid inlet channel, a jet orifice surface having one or more jet orifices fluidly coupled to the fluid inlet channel such that coolant fluid within the fluid inlet channel flows through the one or more jet orifices as one or more impingement jets, and a target surface. The target surface and the jet orifice surface define an impingement chamber where the one or more impingement jets impinge the target surface at an impingement region such that at least some of the coolant fluid changes to a vapor. The cooling apparatus further includes a plurality of sloped vapor outlet channels that are fluidly coupled to the impingement chamber. Coolant fluid flows through the plurality of sloped vapor outlet channels after it impinges the target surface.Type: GrantFiled: November 21, 2012Date of Patent: August 4, 2015Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Joshua Sean Kuhlmann, Shailesh N.

Patent number: 8786078Abstract: Jet-impingement, two-phase cooling apparatuses and power electronics modules having a target surface with single- and two-phase surface enhancement features are disclosed. In one embodiment, a cooling apparatus includes a jet plate surface and a target layer. The jet plate surface includes a jet orifice having a jet orifice geometry, wherein the jet orifice is configured to generate an impingement jet of a coolant fluid. The target layer has a target surface, single-phase surface enhancement features, and two-phase surface enhancement features. The target surface is configured to receive the impingement jet, and the single-phase surface enhancement features and the two-phase enhancement features are arranged on the target surface according to the jet orifice geometry.Type: GrantFiled: December 30, 2013Date of Patent: July 22, 2014Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Purdue Research FoundationInventors: Matthew Joseph Rau, Ercan Mehmet Dede, Shailesh N. Joshi, Suresh V. Garimella
