    摘要: An elongated heat pipe or vapor chamber is described. In examples, the heat pipe may include a tubular body comprising a hollow glass tube or fiber. The heat pipe may further include a wick within the tubular body and a working fluid within the tubular body. The wick may be made of glass, polymer, metal, etc. The wick may be an elongated cylinder disposed within the tubular body and, some cases, may be bonded to an inner floor of the tubular body. In examples, the wick may have an outer diameter substantially equal to an inner diameter of the tubular body. In examples, the wick may have a substantially cross-shaped cross section or may have a helical shape.

    摘要: The present invention provides an energy-storing temperature control material, and belongs to the technical field of temperature control materials. In the energy-storing temperature control material provided in the present invention, the organic synthetic fiber based phase-change material has a three-dimensional dispersion effect, and can form a network constraint for remaining phase-change materials to reinforce mechanical properties of the materials, thereby fixing shapes of the materials and avoiding a liquid-crystal phase separation phenomenon in the phase-change process. The phase-change energy storage agent can absorb and release the heat by means of solid-liquid phase conversion of the material, to achieve the temperature control effect; and the phase-change temperature regulator can regulate a phase-change temperature range of the phase-change material, to make the energy-storing temperature control material suitable for climatic features of northern China.

    摘要: An optical element includes: a phosphor layer excited by excitation light emitted from a light source, and emitting fluorescence; a translucent thermal-conductive layer formed on a face of the phosphor layer that is irradiated with the excitation light; and a non-translucent thermal-conductive layer formed on a face of the phosphor layer that is across from the face irradiated with the excitation light. The translucent thermal-conductive layer has a thermal conductivity higher than, or equal to, a thermal conductivity of the phosphor layer.
