Abstract: A vapor chamber with a support structure and its manufacturing method are provided. The vapor chamber with the support structure includes a first plate, a second plate spaced apart from the first plate, and multiple support elements fixed between the first and second plates. On an outer surface of any of the first plate or the second plate, laser welding is performed on positions corresponding to the support elements so as to join the support elements to the first and second plates and to form weld ports on the outer surface of any of the plates. The invention solves the problem of fixing the support structure inside the thin vapor chamber, and therefore mass production can be realized.

Abstract: A method for brazing a plate heat exchanger comprising a stack of heat exchanger plates (110,115) is provided with a pressed pattern of ridges (R) and grooves (G) adapted to form contact points between the plates (110, 115) and provide for interplate flow channels for media to exchange heat is provided. The interplate flow channels are in selective fluid communications with port openings (120, 130, 140, 150) provided near corners of the heat exchanger plates (110, 115). The method comprises the following steps: calculating or measuring the exact position of all contact points between the ridges (R) and grooves (G) of the neighboring plates (110, 115); applying brazing material (B) close to, but not at, the contact points; stacking heat exchanger plates (110, 115) provided with brazing material to a stack; placing the stack of heat exchanger plates (110, 115) in a furnace; heating the stack of heat exchanger plates (110, 115) to a temperature sufficient for melting the brazing material (B); and allowing the stack of heat exchanger plates (110, 115) to cool down such that the brazing material (B) solidifies and binds the plates (110, 115) together.
