Abstract
A mounting arrangement for an electrical contactor includes a panel and a post. The post has a first end and a second end protruding from the panel. The first end of the post is arranged to electrically communicate with an electrical contactor. The second end of the post is arranged to connect to an electrical bus bar. A cold plate overlays the panel, extends about the post, and is in thermal communication with the post to transfer heat between the cold plate and post.
Claims19
(canceled)
The mounting arrangement as recited in claim 7, wherein the cold plate defines a post aperture, the post extending through the post aperture and being separated from the cold plate by the post aperture.
The mounting arrangement as recited in claim 7, wherein the cold plate defines a fastener aperture that is laterally offset from the post and overlaying the panel.
The mounting arrangement as recited in claim 7, wherein the cold plate comprises an electrically conductive material.

A mounting arrangement for an electrical contactor, comprising:
- a panel;
- a post having a first end and a second end protruding from the panel, the first end configured to connect to an electrical contactor, the second end configured to connect to an electrical bus bar;
- and
- a cold plate extending about the post and overlaying the panel, wherein the cold plate is in thermal communication with the post for transferring heat between the cold plate and the post,
- wherein the cold plate has an inlet, an outlet, and defines with its interior a coolant channel overlaying the panel,
- wherein the coolant channel is a first coolant channel, and wherein the cold plate defines a second coolant channel overlaying the panel.
An electrical contactor assembly, comprising:
- a panel;
- a post having a first end and a second end protruding from the panel, the second end configured to connect to an electrical bus bar;
- an electrical contactor in electrical communication with the first end of the post;
- a cold plate extending about the post and overlaying the panel,
- wherein the cold plate has an inlet and an outlet and defines with its interior and a plurality of coolant channel, wherein the first coolant channel overlays the panel,
- wherein the second coolant channel overlays the panel of a side of the post laterally opposite the first coolant channel, and wherein the cold plate is in thermal communication the post for transferring heat between the post and the cold plate.
An electrical panel assembly, comprising:
- a panel;
- a post having a first end and a second end protruding from the panel, the second end configured to connect to an electrical bus bar;
- an electrical contactor in electrical communication with the first end of the post;
- a bus bar connected to the post, wherein the bus bar is disposed on a side of the panel opposite the cold plate;
- a cold plate extending about the post and overlaying the panel, wherein the cold plate is in thermal communication the post;
- and
- an electrically insulating body, the electrically insulating body overlaying the cold plate, electrically separating the cold plate from the post, and thermally coupling the cold plate with the post,
- wherein the cold plate has an inlet and an outlet and defines with its interior and a plurality of coolant channel, wherein the first coolant channel overlays the panel,
- wherein the second coolant channel overlays the panel of a side of the post laterally opposite the first coolant channel, and wherein the cold plate is in thermal communication the post for transferring heat between the post and the cold plate.
