Abstract
A heat producing, fluid cooled assembly that includes a housing made of liquid-impermeable material, which defines a fluid inlet and a fluid outlet and an opening. Also included is an electrical package having a set of semiconductor electrical devices supported on a substrate and the second major surface is a heat sink adapted to express heat generated from the electrical apparatus and wherein the second major surface defines a rim that is fit to the opening. Further, the housing is constructed so that as fluid travels from the fluid inlet to the fluid outlet it is constrained to flow past the opening thereby placing the fluid in contact with the heat sink.
Claims20
A heat producing, fluid cooled assembly, comprising:
- (a) a housing made of liquid-impermeable material and defining a fluid inlet and a fluid outlet and a plurality of openings;
- (b) a plurality of electrical packages, each having a first major surface and a second major surface and wherein said first major surface supports a set of semiconductor electrical devices and said second major surface is a heat sink adapted to express heat generated from said electrical package and wherein said second major surface defines a rim that is fit to a said opening;
- (c) said housing being constructed so that as fluid travels from said fluid inlet to said fluid outlet it is constrained to flow past each one of said openings thereby placing each said heat sink in contact with said fluid;
- and
- (d) wherein said housing and said electrical packages together form at least one flow volume having fluid entry port and wherein said second major surface includes a set of first protrusions and a set of second protrusions, which are further from said fluid entry port than said first protrusions and wherein said first protrusions are thinner than said second protrusions.
A heat producing, fluid cooled assembly, comprising:
- (a) a housing made of liquid-impermeable material and defining a fluid inlet and a fluid outlet and a plurality of openings;
- (b) a plurality of electrical packages, each having a first major surface and a second major surface and wherein said first major surface supports a set of semiconductor electrical devices and said second major surface is a heat sink adapted to express heat generated from said electrical package and wherein said second major surface defines a rim that is fit to a said opening;
- (c) said housing being constructed so that as fluid travels from said fluid inlet to said fluid outlet it is constrained to flow past each one of said openings thereby placing each said heat sink in contact with said fluid;
- and
- (d) wherein said housing includes a first side defining at least a first one of said openings supporting a first one of said electrical packages and a second side opposed to said first side and defining at least a second one of said openings opposed to said first one of said openings, said second one of said openings supporting a second one of said electrical packages and wherein a flow volume is defined by said housing and said electrical packages.
A heat producing, fluid cooled assembly, comprising:
- (a) a housing made of liquid-impermeable material and defining a fluid inlet and a fluid outlet and a plurality of openings;
- (b) a plurality of electrical packages, each having a first major surface and a second major surface and wherein said first major surface supports a set of semiconductor electrical devices and said second major surface is a heat sink adapted to express heat generated from said electrical package and wherein said second major surface defines a rim that is fit to a said opening;
- (c) said housing being constructed so that as fluid travels from said fluid inlet to said fluid outlet it is constrained to flow, in parallel, past each one of said openings thereby placing each said heat sink in contact with said fluid;
- and
- (d) wherein said housing is formed so as to cause an equal fluid flow past each said opening.
