Abstract: Disclosed is an electronic assembly that includes a heat sink with a groove that is cut on a surface of the heat sink. A thermal interface material is disposed between the heat sink and an electronic device. A compressible filler disposed in the groove surrounds and confines the thermal interface material.

Abstract: An immersion cooling system includes a tank that contains a dielectric coolant. A main pump circulates the dielectric coolant through the tank and a heat exchanger. Electronic devices are submerged in the dielectric coolant in the tank. An electronic device includes a substrate, an electronic component that is mounted on the substrate, a heat sink that is attached to the electronic component, and a forced convection device that directs the dielectric coolant from within a housing of the electronic device toward the heat sink.

Abstract: A liquid tank system includes a tank body and a liquid coolant supplying device. The tank body has an accommodating space, a liquid inlet, and an upper outlet. The liquid inlet and the upper outlet communicate with the accommodating space. The accommodating space is sealed except for the liquid inlet and the upper outlet. The liquid coolant supplying device is connected to the liquid inlet so as to continuously provide a liquid coolant to the accommodating space through the liquid inlet. The liquid coolant in the accommodating space overflows out of the tank body through the upper outlet. A Li-ion battery cooling system includes a Li-ion battery and the above liquid tank system. The Li-ion battery is disposed in the accommodating space and submerged in the liquid coolant. The continuously flowing liquid coolant dissipates heat from the lithium battery.

Abstract: An airflow-guiding device for a light source includes a cap and a guiding element. The cap has an airflow inlet, a through opening, an airflow outlet, a foundation, an annular side wall, and a cover. The foundation is connected to a reflector of the light source. The through opening is located at the foundation and corresponding to a light outlet of the reflector. The annular side wall where the airflow inlet is located is disposed on the foundation. The cover where the airflow outlet is located is disposed on the annular side wall and opposite to the foundation. The guiding element includes a guiding opening and an annular body. The annular body is rotatably disposed in the cap. The annular body where the guiding opening is located surrounds at least part of the through opening and forms a guiding tunnel together with the annular side wall in the cap.

Abstract: A lamp source module includes a holder having an air inlet and an air outlet, a gas discharge lamp having a lamp reflector assembled onto the holder and a burner disposed in the lamp reflector, a light cover assembled on the holder and surrounding the lamp reflector, a blower duct communicating with the air inlet and extending along the exterior of the lamp reflector to the bottom of the lamp reflector, and an airflow generator communicating with the blower duct and capable of providing a cooling airflow. The air inlet is capable of causing the cooling airflow to enter the blower duct. The blower duct is capable of directing the cooling airflow to the bottom of the lamp reflector to make the cooling airflow pass through a sandwiched space surrounded by the lamp reflector and the light cover and then discharge from the air outlet.

Abstract: A projector includes a light source, a fan and a guiding passage. The fan is disposed beside a first side of the light source. The guiding passage has a guiding inlet and a guiding outlet. The guiding passage extends from a section near the fan to a section near a second side of the light source. The fan is capable of generating a first airflow and a second airflow. The first airflow is capable of being mixed with the second airflow near the second side of the light source. The second airflow is guided by the guiding passage so that the second airflow is mixed with the first airflow near the second side of the light source.
