A hybrid heat pipe assembly comprising: a baseplate dimensioned to be placed in surface contact with a device, the baseplate being configured to extract heat from the device, the baseplate having a channel formed within the baseplate at a location on one side of the base plate that is essentially opposite a location on another side of the baseplate at which the device is in surface contact with the baseplate; a plurality of fins bonded to the baseplate in parallel, the fins bonded to the baseplate being configured to transfer a first portion of the extracted heat from the baseplate to air surrounding the fins bonded to the baseplate; a complex heat pipe apparatus comprising a closed chamber positioned within the baseplate, embedded within the channel, and welded to walls that define the channel, the apparatus further comprising a plurality of complex heat pipes, the complex heat pipes being secured within respective recesses of said closed chamber by brazing the complex heat pipes to respective walls that define the recesses, the complex heat pipes extending from the baseplate through the fins bonded to the baseplate, the closed chamber being configured to act within the baseplate as a reservoir for the fluid to expedite the transfer of a second portion of the extracted heat from the baseplate using a two-phase flow cycle created within the complex heat pipes, the closed chamber being configured to transfer the second heat portion from the chamber to the complex heat pipes, the complex heat pipes being configured to receive the second heat portion; and a heat pipe fin stack through which the complex heat pipes extend and to which the complex heat pipes are configured to transfer the second portion of heat, the heat pipe fin stack being joined to the complex heat pipes and configured to transfer the second portion of the extracted heat received from the complex heat pipes to air surrounding the stack, wherein the heat pipe fin stack comprises a heat pipe protective fin into which the complex heat pipe extends, wherein the heat pipe protective fin is positioned on an opposite side of the heat pipe fin stack from the fins bonded to the baseplate, wherein the heat pipe protective fin is positioned adjacent to one end of each of the complex heat pipes, wherein an end cap is positioned on the one end of the complex heat pipes, wherein each of the complex heat pipes extends from the baseplate to an end of each of the complex heat pipes at an oblique angle, and wherein fins of the heat pipe fin stack extend in parallel to a side of the baseplate in which the channel is formed. a baseplate dimensioned to be placed in surface contact with a device, the baseplate being configured to extract heat from the device, the baseplate having a channel formed within the baseplate at a location on one side of the base plate that is essentially opposite a location on another side of the baseplate at which the device is in surface contact with the baseplate;
