1. A heatsink assembly for an unmanned aerial vehicle comprising:
a first heat pipe including a first transfer portion between a first end portion and a second end portion;
a second heat pipe including a second transfer portion between a third end portion and a fourth end portion;
a first metallic heat transfer element thermally connected to the first end portion;
a second metallic heat transfer element thermally connected to the third end portion;
a third metallic heat transfer element thermally connected to the second end portion and the fourth end portion;
a computer processing unit that produces heat that is thermally connected to the third metallic heat transfer element;
a first electrically insulating thermoplastic element into which the first metallic heat transfer element fits such that a surface area of the first metallic heat transfer element is thermally connected to an outside ambient environment where the first electrically insulating thermoplastic element is not between the outside ambient environment and the first metallic heat transfer element; and a second electrically insulating thermoplastic element into which the second metallic heat transfer element fits such that a surface area of the second metallic heat transfer element is thermally connected to the outside ambient environment where the second electrically insulating thermoplastic element is not between the outside ambient environment and the second metallic heat transfer element,
wherein the first heat pipe includes a first wick structure and a first embedded liquid providing thermal transport within the first heat pipe while at least some of the first embedded liquid is above a threshold temperature,
wherein the second heat pipe includes a second wick structure and a second embedded liquid providing thermal transport within the second heat pipe while at least some of the second embedded liquid is above the threshold temperature,
wherein the unmanned aerial vehicle is at least operable at temperatures above −40° C. degrees and is at least operable at temperatures below 70° C., and
wherein the threshold temperature is between −40° C. and 70° C.
