Abrégé
A closed integrated heat-dissipation assembly and a liquid cooling module thereof are disclosed. The heat-dissipation assembly includes a heat sink plate, plural power modules, an accelerator, a flow channel plate, an inlet pipe and an outlet pipe. The heat sink plate includes a top surface, a bottom surface and plural pin fins arranged on the bottom surface. The power modules are directly disposed on the top surface of the heat sink plate. The accelerator is combined with the pin fins to form a cooling flow channel. The flow channel plate is closely assembled with the bottom surface of the heat sink plate. The flow channel plate includes an inlet and an outlet connected to an inflow chamber and an outflow chamber, respectively, and in communication with each other through the cooling flow channel. The inflow pipe and the outflow pipe are connected to the inlet and the outlet respectively.

Abrégé
A water pump control device is disclosed, in which a switching module powered by a system power supply receives information from a sensor and/or an emergency switch to generate a control signal to control a power switch to connect or disconnect a power supply path between a water pump and a water pump power supply according to the control signal. Therefore, in a cooling system, in the event of liquid leakage, abnormal water level, or an alarm signal issued by an emergency switch, the switching module can independently cut off the power source of the water pump via the power switch, such that the water pump can effectively stop running and avoid the scope of influence is expanded. At the same time, components other than the water pump can still be powered and operated as usual, avoiding other control abnormalities caused by power outages of the water pump.

A liquid supply device includes a liquid storage tank and at least one liquid pipe. The liquid storage tank includes a housing and a partition. The housing has an accommodation space, an inlet and at least one outlet. The partition is disposed in the accommodation space and divides the accommodation space into a first space and a second space. The inlet communicates with the first space, and the outlet communicates with the second space. The second space is of greater volume than the first space. The partition has at least two openings through which the first space and the second space communicate with each other. The liquid pipe is connected to at least one of the inlet and the outlet of the housing.

Abrégé
A power conversion circuit is coupled to a motor and a wireless charging transmitter device. Power conversion circuit includes an inverter and a processor. Inverter includes three half-bridge circuits. Three half-bridge circuits are respectively coupled to a battery, motor and wireless charging transmitter device. Each of three half-bridge circuits includes two switches. Processor is coupled to switches of three half-bridge circuits and generates a plurality of control signals at a first stage to respectively control switches according to a first level of each of control signals, so that battery supplies power to motor. Processor adjusts first level of each of control signals to a second level during a second stage to turn off one of three half-bridge and to turn on switches of the other two of three half-bridge alternately so as to adjust a power supply of wireless charging transmitter device to charge battery to a target power.
