Abstract: Heat dissipation systems, apparatus, articles of manufacture, and methods are disclosed. An example computing device includes a display, a keyboard, processor circuitry, and a dual-phase heat dissipation system. The dual-phase dissipation system includes a housing defining a chamber, a fluid inlet, and a fluid outlet. The chamber receives a working fluid via the fluid inlet. A pump fluidly couples to the fluid inlet and the fluid outlet of the housing. The pump is to receive the working fluid via the fluid outlet of the housing and increase at least one of a flow rate or volume of the working fluid at the fluid inlet.

Abstract: According to one aspect of the invention, a method of manufacturing an impingement sleeve for a turbine engine combustor includes placing a first metal sheet in a first die, pressing the first metal sheet in the first die to form a first vertical half of the impingement sleeve, placing a second metal sheet in a second die and pressing the second metal sheet in the second die to form a second vertical half of the impingement sleeve. The method also includes forming holes in the first vertical half and second vertical half while the first vertical half and second vertical half remain separate, positioning the first vertical half and second vertical half about a transition piece and welding the first vertical half to the second vertical half to form the impingement sleeve.
