The present invention relates to a flow rate measuring method comprising: establishing a database which includes a plurality of flow profiles; measuring the flow in a flow field using a plurality of transducers wherein in between every two transducers there exists an acoustic path which indicates the flow speed of the flow between the two transducers, and a feature map can be derived from the flow speeds; comparing the feature map with the database; selecting a matching flow profile from the flow profiles wherein the matching flow profile has a plurality of weighting functions corresponding to the acoustic paths; and calibrating the flow speed using the weighting functions.

Flow rate measuring method

A dehumidification device with enhanced dehumidification effect includes a gas cooler receiving a first air gas and condensing the first air gas into a first condensing gas and a first condensing liquid. A heat exchanger has an inlet and an outlet. The first condensing gas flows from the gas cooler to a periphery of the heat exchanger to cool the heat exchanger. The inlet receives a second air gas from outside. The second air gas is condensed into a second condensing gas and a second condensing liquid using the cooled heat exchanger, and the second condensing gas and the second condensing liquid are expelled from the outlet. A gas heater receives the first condensing gas flowing through the periphery of the heat exchanger and the second condensing gas expelled from the outlet, and heats and turns them into dry air, and the gas heater expels the dry air.

A heat conducting module includes a main body. The main body includes a first surface and a second surface. The first surface is thermally connected to a heat absorbing body. The second surface is opposite to the first surface and is fluidly connected to a channel. The second surface has a plurality of grooves disposed along a direction. The channel allows a fluid to flow a long the direction. Each of the grooves includes a first sub-groove and at least one second sub-groove. The first sub-groove at least has a third surface close to the first surface. The first sub-groove at least partially communicates with the second sub-groove, and the second sub-groove is at least partially fluidly connected with the third surface.

Heat conducting module

A cold plate including a cold wall, a first cavity, a first pipe, a second cavity, an expansion unit and a second pipe is provided. The first cavity covers on the cold wall to form a first fluid space, and the first pipe is connected with the first cavity. The second cavity is disposed inside the first cavity and covers on the cold wall to form a second fluid space. The expansion unit is disposed between the second cavity and the cold wall to interconnect the first fluid space and the second fluid space. The second pipe is disposed inside the first pipe and connected with the second cavity. Besides, a refrigeration system including the cold plate mentioned above is also provided.

Cold plate and refrigeration system

An evaporator, applicable to a two-stage expansion cooling system, is used for receiving a high-pressure liquid working fluid. The evaporator includes a thermal-conductive block having a channel system. The channel system includes a high-pressure channel, a low-pressure channel, and a second stage expansion channel. The second stage expansion channel has an input end and an output end. The input end is communicated with the high-pressure channel. The output end is communicated with the low-pressure channel, and has a cross-sectional area smaller than that of the low-pressure channel. The high-pressure liquid working fluid flows into the thermal-conductive block from the high-pressure channel, and then enters the second stage expansion channel through the input end. A part of the high-pressure liquid working fluid flowing out of the output end expands into a saturated low-pressure liquid working fluid and enters the low-pressure channel.
