A sensing device includes a housing positioned on an outer surface of a wire and a circuit board received in the housing. The circuit board has a sensing area for sensing the wire, such that the measurements obtained by the circuit board are relative values. Therefore, the circuit design of the circuit board can be simplified, and the size of the sensing device can be reduced.

A module for data center is presented, which is used for heat sinking of a heat source. The module for data center includes a first chamber, a second chamber, and a heat pipe. The heat source is positioned in the first chamber. The second chamber is adjacent to the first chamber. In addition, the heat pipe has an evaporation end positioned inside the first chamber and a condensation end positioned inside the second chamber. The heat pipe absorbs the heat energy in the first chamber with the evaporation end, transfers the heat energy to the condensation end, and eliminates the heat energy with the condensation end.

An air conditioning system includes a first circulation module and a second circulation module. Two circulation modules are joined by a heat exchanger. The first circulation is a modular refrigeration system includes a compressor, expansion device, and heat exchangers. The second circulation module includes a main liquid refrigerant tank, a number of distributed liquid refrigerant tanks, liquid pumps and a plurality of indoor units which includes a heat exchange device and a vapor propelling device. The heat exchange device is connected to the main liquid tank. The vapor propelling device propels the working fluid in a saturated vapor state to the first heat exchanger, thus forming a working fluid loop. It can be switched between the heating and cooling modes.

Air conditioning system

A structure of heat dissipation of an electronic device includes at least one heat pipe and a cooler. The heat pipe has a condensation end and an evaporation end opposite to each other, and the evaporation end is disposed on a heat generating element of the electronic device. The cooler is disposed on a rack and has a chamber therein, and the chamber has an inner shell having a cooling fluid therein. When the electronic device is mounted in the rack, the condensation end of the heat pipe is inserted into the cooler and positioned into the inner shell. The evaporation end absorbs the heat energy of the heat generating element, and transfers the heat energy to the condensation end, such that the cooling fluid dissipates the heat energy of the condensation end.

Heat dissipation structure of electronic device

In the present invention, a method and a system for controlling a compressor are provided. The method includes the steps of: providing a condenser connected to the compressor, and at least one evaporator connected to the condenser; measuring an inlet pressure and an outlet pressure of the compressor to obtain a flow rate of the condensate; determining a secure flow rate and a demanding flow rate based on a total number of the at least one evaporator; comparing at least two of the flow rate, the demanding flow rate and the secure flow rate with each other to obtain a compared result; and controlling the compressor based on the comparing result.

A refrigerant floating expansion apparatus including a main body, a standpipe, a float element and a separation element is provided. The main body includes a base plate and a pipe-shaped housing. The standpipe fixed on the base plate has a second pipe opening and a third pipe opening. The pipe wall of the standpipe has at least an opening near the second pipe opening. The float element surrounds the standpipe for controlling a fluid-passing area of the opening. The separation element surrounding the float element is disposed on the base plate and forms an inner path with the pipe-shaped housing. The separation element has several fluid passageways near the base plate. A high-pressure fluid entering the main body is guided to pass through the fluid passageways to move the float element for controlling the fluid-passing area of the opening. Then, the high-pressure fluid is transferred to a low-pressure fluid.
