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.

An air transfer apparatus or enclosure having a heat exchanger attached to at least one side of the air transfer apparatus. The air transfer apparatus is an integral or a monolithic structure or enclosure where all internal cavities of the air transfer apparatus are formed from a single piece of material. The air transfer apparatus or enclosure includes a drain apparatus and a drain device. The drain apparatus includes a plurality of plates and the plurality of plates are positioned to make any collected fluid thereon collect in a sump of the air transfer apparatus.

A cooling tower system is disclosed. The cooling system includes a cooling tower; at least two make-up water inlet streams configured to supply water to the cooling tower; a blowdown stream configured to remove water from the cooling tower; at least one sensor monitoring water in each of the make-up water inlet streams; and a controller operably connected to the at least one sensor.

A heat exchanger which may be used in an engine, such as a vehicle engine for an aircraft or orbital launch vehicle. is provided. The heat exchanger may be configured as generally drum-shaped with a multitude of spiral sections, each containing numerous small diameter tubes. The spiral sections may spiral inside one another.
