A heat dissipation apparatus. A fan frame includes an air inlet, an air outlet, a passage, and a curved expansion portion. The air inlet is opposite the air outlet. The passage is between the air inlet and the air outlet, guiding airflow from the air inlet to the air outlet. The curved expansion portion is radially and outwardly extended from an inner peripheral wall of the passage at the air inlet or air outlet. An impeller is disposed in the fan frame and includes a plurality of blades. Each blade is disposed in the passage and includes an extension end extending to the curved expansion portion.

A heat dissipation apparatus. A fan frame accommodates an impeller therein and includes an air inlet, an air outlet, and a passage for guiding airflow from the air inlet to the air outlet. An inner peripheral wall of the passage radially and outwardly extends a smooth curved expansion portion at the air outlet. The curved expansion portion includes a recess in which the airflow forms an airflow layer, stopping subsequent airflow from directly contacting the inner peripheral wall of the passage.

A composite heat-dissipating device is provided for significantly increasing the number and size of blades so as to enhance the heat-dissipating performance. The composite heat-dissipating device is constructed by a plurality of impellers, each of which includes a plurality of blades. When the plurality of impellers are assembled together, the plurality of blades are arranged around the hub of the composite heat-dissipating device and there is an overlapped region formed between every two adjacent blades.

A heat-dissipating module includes a heat sink and a fan device. The fan device may be disposed on the heat sink, or inserted into the heat sink to reduce the height. The fan device includes a first rotor blade and a second rotor blade. The first rotor blade and the second rotor blade are connected in series. The rotation speed of the first rotor blade is controlled by a first control circuit, and the second rotor blade is controlled by the second circuit. Thus, the second control circuit increases the rotation speed of the second rotor blades when the first rotor blades is failed.

A substrate cleaning apparatus includes a chamber having a substrate support capable of supporting and rotating a substrate in the chamber. A cleaning solution injector is provided to inject a cleaning solution onto the substrate in the chamber. A portion of the cleaning solution is thrown off the rotating substrate to form a cleaning solution mist in the chamber. A cleaning gas inlet introduces a cleaning gas into the chamber and an outlet exhausts the cleaning solution mist and cleaning gas from the chamber. This reduces the formation of residues from the cleaning solution mist on the substrate.

The present disclosure generally pertains to green oxidizer compositions and method of synthesizing and using the same. Such green oxidizers are stable, may be used in conventional bipropellant thrusters, including, but not limited to LDACS applications, and offer several benefits over conventional oxidizers with respect to toxicity and/or corrosion. The present disclosure also relates to methods of synthesizing poly-nitrated oxetane, a green oxidizer, in an Argon-rich environment.
