The invention discloses a building outer wall structure with double shaping phase change material layers. The building outer wall structure sequentially comprises the outer shaping phase change wall board layer, a first thermal insulation layer, a wall body layer, a second thermal insulation layer, the inner shaping phase change wall board layer from outside to inside, wherein the outer shaping phase change wall board layer and the inner shaping phase change wall board layer are respectively made of phase change materials of phase change temperatures of Tm1 and Tm2, the phase change temperature Tm1 is set to be minimum in cold load all year round in the expositing environment of the phase change temperature Tm1, and the solid phase change materials melt into liquid phase change materials when the wall board layer temperature is equal to or higher than Tm1; the phase change temperature Tm2 is set to be minimum in heat load all year round in the exposing environment of the phase change temperature Tm2, and the solid phase change materials melt into liquid phase change materials when the wall board layer temperature is equal to or higher than Tm2. The invention further designs the components and proportion of the phase change materials of the two shaping phase change wall board layers. By the building outer wall structure which is compact, high in adaptability, convenient to manufacture and maintain later, and the like, outer wall cold load and heat load can be lowered effectively, and overall energy consumption is lowered evidently.

The invention relates to an LED street lamp, which comprises a lamp shell, a heat radiator arranged on one end face of the lamp shell, a lampshade arranged on the other end face of the lamp shell, and a driver arranged in the lamp shell, wherein heat transfer devices are arranged in lamp shell cavities which are positioned on the heat radiator and are coaxial with the lampshade respectively, the bottom of the heat transfer device is connected with a high-brightness light source, and a reflecting shade of which the covering surface corresponds to a transparent surface of the lampshade is clamped between the bottom of the heat transfer device and the high-brightness light source. The heat transfer device consists of a sealed cavity formed by a conical shell and the heat radiator, and a heatconducting fusing agent filled in the sealed cavity. The LED street lamp uses vaporization heat transfer and liquefaction heat exchange to heat the heat transfer liquid by the heat generated in the working process of an LED module through the heat transfer shell, and when the temperature reaches the boiling point of the heat transfer liquid, the liquid is boiled and vaporized, the gas can quicklytransfer the heat to the heat radiator, and the heat radiator liquefies the gas into liquid which falls back to the heat transfer shell for transferring heat continuously after the heat exchange between the heat radiator and the heat transfer gas.
