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 power supply apparatus is coupled to an AC power source, a critical load, and a general load. The power supply apparatus includes a UPS, a generator system, a power conversion system, and a controller. The power conversion system includes a first power conversion path and a second power conversion path. The first power conversion path is connected to the critical load and an output side, and the second power conversion path is connected to the general load and an input side. The first power conversion path and the second power conversion path are jointly connected to a DC bus. When the controller determines that the AC power source is abnormal, the controller controls disconnecting the AC power source, and activates the UPS to supply power to the critical load so as to enable the first power conversion path and disable the second power conversion path.
