Abstract: A cooling apparatus is provided. An external cooling fluid flows into an external inlet opening from an external inlet pipe and passes through a heat exchanger to flow out of an external outlet opening to an external outlet pipe. An internal cooling fluid flows into an internal inlet pipe from the server and flows into an internal inlet opening from the internal inlet pipe and passes through the heat exchanger for heat exchange with the external cooling fluid to flow out of an internal outlet opening to an internal outlet pipe. A hot-swap pump has a pump main body, an inlet anti-leakage pipe, an outlet anti-leakage pipe and a hot-swap connector. The inlet anti-leakage pipe includes an inlet connector and an inlet anti-leakage valve. The outlet anti-leakage pipe includes an outlet connector and an outlet anti-leakage valve. The hot-swap connector is electrically connected to the pump main body.

Abstract: A trigger switch module suitable for use with various household appliances and instruments is capable of generating a signal needed by a microcontroller via a human-machine interface, so that the trigger switch module has stable signal level output pins for a microprocessor or a logic gate to make judgment easily. The trigger switch module can be triggered to output a signal through a non-direct contact of the switch at low voltage and low power consumption. All components of the trigger switch module are enclosed in a top casing that is completely watertight and dustproof to ensure stable capacity of the switch. The trigger switch module combines the functions of conventional switches but eliminates drawbacks thereof. A touch panel made of plastics, metal, glass, ceramic or other insulating material may be provided with the top casing to ensure safe and durable use of the trigger switch module.
