In an embodiment, a method of forming a cooling plate, comprises laser welding a plurality of weld lines to physically connect a first substrate and a second substrate wherein the plurality of weld lines forms an inflatable track; and inflating the inflatable track with an inflation fluid to form a cooling channel in the cooling plate. In another embodiment, the cooling plate can comprise a first substrate and a second substrate and a plurality of weld lines can form a fluid tight seal for a cooling channel located therebetween.

A microtube heat exchanger is disclosed, including two end plates with an array of holes or openings and an array of microtubes disposed in the array of openings between the two end plates. The heat exchanger can be used in environmental control systems, including systems for aerospace applications.

The present application discloses two-phase cooling devices that may include at least three substrates: a metal with a wicking structure, an intermediate substrate and a backplane. A fluid may be contained within the wicking structure and vapor cavity for transporting thermal energy from one region of the thermal ground plane to another region of the thermal ground plane, wherein the fluid may be driven by capillary forces within the wicking structure. The titanium thermal ground plane may be adapted for use in a mobile device, such as a portable device or smartphone, where it may offer compelling performance advantages.

The present invention provides a heat transfer equipment at rapid rate of thermal diffusion across the temperature gradient. The present invention further provides a method of manufacturing of a heat transfer equipment. The various embodiments of the present invention provide various methods for manufacturing of heat transfer equipment by affixing the loop or a solid member (201) containing crests and troughs on the surface of the central hollow member (101) by use of laser weld (301). The invention would provide much higher strength to the equipment and have much higher temperature sensitivity.

A vapor chamber and an electronic device are provided. The vapor chamber includes a first sheet including a first flat portion and a first bending portion bent, at an edge of the first flat portion, to be inclined at a first angle for the first flat portion, a second sheet including a second flat portion and a second bending portion bent, at an edge of the second flat portion, to be inclined at a second angle for the second flat portion, and a side portion formed by bonding the first bending portion and the second bending portion. A bonding surface between the first bending portion and the second bending portion may be disposed to be inclined from or perpendicular to an outer surface of the side portion.

Exemplary embodiments are directed to swimming pool heat exchangers including a housing and one or more tube assemblies disposed within the housing. Each of the tube assemblies includes an elongated titanium tube and at least one fin welded to an outer surface of the elongated titanium tube. The elongated titanium tube and the at least one welded fin allow for corrosion resistance to swimming pool water while simultaneously allowing for improved heat transfer from the heat exchanger to the swimming pool water.
