Abstract: A heat pipe has a tube and an evaporator wick. The tube has multiple groove structures, an evaporator section, and a condenser section. The groove structures are disposed on an inner surface of the tube and extend to two opposite ends of the tube to reduce flow resistance of liquid phase working fluid. The evaporator wick is disposed in the evaporator section. The evaporator wick is made of metal powder and sintered to adhere to the groove structures. The evaporator wick is uniform in thickness and uniformly adheres to the groove structures. The evaporator wick vaporizes the working fluid in the evaporator section. As a result, the heat pipe has good manufacturing process repeatability and is reliable, easy to manufacture, and low-cost.

Abstract: Most protective masks are not designed to follow individual facial contours and have a limited ability to adjust to various facial sizes and shapes. A sealing cushion for use with surgical face masks and the like has a pliant body with a tacky surface and a wire embedded within, which together create a frame-like structure having a central aperture. The wire encased within the body of the cushion allows the apparatus to be shaped and fitted to the contours of the face to create a substantially airtight seal between the face and the mask. The sealing cushion can prevent or reduce entry of airborne contaminants around the sides and edges of the mask.

Abstract: A desiccant wheel is provided to be rotatable. Through the body of the wheel or a surface adsorbent, water vapor in humid air flow is adsorbed. By passing a high-temperature air flow through the wheel, the body or surface coating is regenerated with moisture removed. Along a cross-section radial, the wheel is divided into different areas. The body has three-dimensionally inter-connected pores. The pores can be of different types. The wheel is a complete concentric cylinder or a concentric cylinder comprising equal or unequal sectors. The equal or unequal sectors are separated with each other. The wheel can rotate at a fixed speed for continually repeating a process of adsorbing, transiting, and regenerating. Thereby, drying can be carried out without causing physical or chemical change to heat-sensitive material, which also improves drying efficiency, reduces size, lowers power consumption, and helps in carbon reduction for industry.
