  • Publication number: 20210381947
    Abstract: A gas detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a light-emitting element, a particle-sensing element, a gas-sensing element, a driving-chip element and an encapsulation layer. The driving-chip element controls driving operations of the microelectromechanical element, the light-emitting element, the particle-sensing element and the gas-sensing element, respectively. When the microelectromechanical element is enabled to actuate transportation of gas, the gas is introduced into the gas detection device through an inlet aperture of the substrate. Scattered light spots generated by the light beam of the light-emitting element irradiating on suspended particles contained in the gas are received by the particle-sensing element to generate a detection datum of the suspended particles. The gas-sensing element detects the gas passing through and generates a detection datum of hazardous gas contained in the gas.

    Abstract: A vapor chamber structure for heat dissipation of a heat source is provided. The vapor chamber structure includes a housing having a heat absorption side and a heat dissipation side, a first capillary structure disposed in the housing, and a working fluid filled in the housing. The first capillary structure is formed into cavities isolated from each other, and each of the cavities is connected between the heat absorption side and the heat dissipation side. Heat generated by the heat source is absorbed by the heat absorption side, thereby transforming the working fluid from liquid state to vapor state. The working fluid in the vapor state is transmitted to the heat dissipation side via the cavities, and is transformed to the liquid state while the heat is dissipated. The working fluid in the liquid state returns to the heat absorption side via the first capillary structure.
