A vapor chamber that includes a housing having a first sheet and a second sheet that oppose each other and that are joined to each other in a peripheral region of the housing; a working liquid enclosed within the housing; and a wick structure on an inside surface of the first sheet or the second sheet. In the vapor chamber, the wick structure includes multiple protruding portions and a grid portion integral with the protruding portions. In addition, surfaces of the protruding portions and a surface of the grid portion opposite the inside surface of the first sheet or the second sheet are positioned on a same flat surface.

A heat exchanger includes a fluid reservoir having a peripherally extending foot, a header having a mounting tab bent to engage the foot of the fluid reservoir to couple the header to the fluid reservoir, and a retaining feature configured to prevent disengagement of the mounting tab of the header from the foot of the fluid reservoir. The retaining feature overlays at least a portion of an outer surface of the mounting tab while otherwise restrained by a portion of the fluid reservoir in order to prevent the disengagement of the mounting tab from the foot.

A forming assembly for forming a wick is disclosed. The forming assembly includes a tube inflatable to an inflated configuration. A wick mesh is configured to be wrapped about the tube. The forming assembly further includes a sheath positionable about the tube and the wick mesh. The tube and the sheath are configured to compress the wick mesh and form the wick based on the tube inflating towards the inflated configuration.

A heat dissipation device includes a body including a first metal sheet and a second metal sheet coupled to the first metal sheet. The first metal sheet at least partially defines a first channel including a first plurality of curves, a second channel including a second plurality of curves, and an interconnecting channel fluidly coupled to the first channel and the second channel. The first channel and the interconnecting channel at least partially surround the second channel, a unit volume of the first channel is a same as a unit volume of the interconnecting channel, and the unit volumes of the first channel and the interconnecting channel are different from a unit volume of the second channel.
