摘要： A reverse-return parallel loop system is provided, including a cooling cycle comprised of a plurality of heat sinks, at least one heat exchanger, and at least one liquid pump to carry liquid coolant through the system. Each heat sink has a vapor inlet, a liquid inlet, a vapor outlet, and a liquid outlet. The liquid coolant is pumped into the heat sink through the liquid inlet where the coolant splits in to two streams, where one stream flows out of the liquid outlet towards the next heat sink downstream, and the other stream flows through the heat sink, and through the heat exchanger core to absorb heat from the heat sources and become at least partially vaporized by the heat. This stream then merges with vapor from other heat sinks upstream and flows out through the vapor outlet back towards the heat exchanger of the system.

摘要： An apparatus and method for burning-in an electronic ballast for a lamp. The apparatus comprises a first stage for emulating an input impedance characteristic of a lamp for the electronic ballast and a second stage connected to the first stage for providing energy feedback to a power supply. An input of the first stage connects in use to the electronic ballast to be burnt-in. An output of the second stage connects in use to the power supply to provide energy feedback to said power supply from the electronic ballast being burnt-in. The energy-recyclable burn-in apparatus can emulate the lamp characteristics from start up to the steady state, process high-frequency ballast output power and recycle the power back into the power grid. The burn-in method includes operating the apparatus for a predetermined period of time such that a voltage applied to the electronic ballast simulates a steady-state operation of a lamp for the electronic ballast.
