摘要： The present invention discloses a detection device and a probe module thereof, wherein an electrical connection path between a battery detection frame and a battery under test is provided via the probe module. The probe module includes a base, a first polarity plate, a second polarity plate, a first upper connection group, a second upper connection group, a first lower connection member and a second lower connection member. Via the first polarity plate, the first upper connection group is correspondingly coupled to the battery detection frame, and the first lower connection member is correspondingly coupled to the battery under test. Via the second polarity plate, the second upper connection group is correspondingly coupled to the battery detection frame, and the second lower connection member is correspondingly coupled to the battery under test. Thus, it is not necessary to process a cable having been fixed on the battery detection frame when the probe module is replaced. Moreover, since each polarity has dedicated coupling elements respectively corresponding to the battery detection frame and the battery under test, reliability is enhanced.

摘要： A micro device under test (DUT) carrier includes a carrier main body, a pusher and a spring. The carrier main body includes a plurality of bearing stages. Each bearing stage is utilized to bear a micro DUT. The pusher, operated to move from a locking position to an opening position, includes a pusher main body and a plurality of locking elements. Each locking element corresponds to each bearing stage, and is located next to each bearing stage. The spring is utilized to send the pusher back to the locking position, so that each locking element restricts movement of each micro DUT.

摘要： A heat exchange device and a cooling system are provided. The heat exchange device includes a low-pressure chamber and a high-pressure chamber disposed in the low-pressure chamber. The low-pressure chamber has a first wall for enabling heat exchange and an output portion in communication with the outside to output the low-pressure fluid. The high-pressure chamber has an input portion in communication with the outside to admit the high-pressure fluid and nozzles in communication with the low-pressure chamber. The fluid discharged from the nozzles undergoes a pressure drop and undergoes heat exchange through the first wall. Cooling capability is developed in the heat exchange device and works in the heat exchange device to thereby dispense with a pipeline which must be otherwise provided to link an expansion process and an evaporation process of the fluid and may otherwise cause cooling capability loss, so as to greatly enhance heat exchange capability and cooling efficiency.

摘要： The present invention relates to an AC/DC power conversion module and a method of driving the same. When an AC/DC converter is electrically coupled to an external power source, a microprocessor is electrically energized by a buck auxiliary circuit, under control of the microprocessor, a DC/DC converter is activated for a certain time period, and then, the AC/DC converter is activated. Thereafter, an output voltage of the AC/DC converter is boosted, and an output voltage of the DC/DC converter is boosted accordingly. Power elements in the downstream side DC/DC converter are activated first, and then power elements in the upstream side AC/DC converter are activated, thereby an inrush current is suppressed. Once the external power source is connected, the buck auxiliary circuit will automatically reduce a voltage of the power input to activate the module. It realizes that the module will autonomously operate after being electrically energized.
