An apparatus includes a heat sink and a post that supports the heat sink that is monolithically formed with the heat sink. The apparatus can further include a printed wiring board attached to a top side of the heat sink with electronic components attached to the printed wiring board, a plurality of posts integrated into a bottom side of the heat sink and extending outwards from the heat sink, wherein the heat sink and the plurality of posts are monolithically formed, and a heat pipe attached to the bottom side of the heat sink with a first end near an electronic component and a second end near one of the plurality of posts.

Heat pipe embedded heat sink with integrated posts

An electronics chassis for containing and supporting electronic components having different operating temperatures includes a plurality of thermally conductive walls forming an enclosure. There is a first heat dissipator in at least one of the walls having an external heat dissipator and a second heat dissipator in at least one of the walls having an external heat dissipator. There is a thermal isolator positioned in at least one of the walls to provide thermal isolation between the heat dissipators, and the thermal isolator includes a thermally insulating material.

Thermal separation of electronic control chassis heatsink fins

An apparatus includes a printed wiring board, a post that supports the printed wiring board, and a heat pipe on the printed wiring board with a first end positioned near an electronic component attached to the printed wiring board and a second end positioned near the post.

PWB cooling system with heat dissipation through posts

An electronic component and cooling system has a printed wiring board, which is planar. An electrical component is mounted on one side of the planar surface of the printed wiring board. A hood is positioned outwardly of the electronic component. Legs on the hood extend to the printed wiring board, and form an inner surface that is positioned away from the one side relative to the electrical component. A chassis has posts connected to the printed wiring board and on an opposed side of the planar surface of the printed wiring board from the electrical component. The chassis extends to a remote portion, beyond the printed wiring board. A heat pipe is generally elongate and positioned on an opposed side of the hood from the electrical component. The heat pipe extends to the remote portion of the chassis to transfer heat from the hood to the chassis.

Electronic component cooling hood and heat pipe

An electric motor controller includes controller electronics configured to control an electric motor. The electric motor controller also includes a thermoelectric cooler in thermal communication with the controller electronics. The thermoelectric cooler is configured to receive a braking current associated with braking of the electric motor and provide cooling to the controller electronics.
