Abstract: A condenser in a gravity loop heat pipe heat sink and a method for producing the condenser are disclosed. The production method includes the following steps: squeezing a base material of a condenser to form a condenser substrate and several longitudinal channels of the condenser, where the longitudinal channels of the condenser are parallel to and thread through the condenser substrate; drilling holes at the two ends of the condenser substrate to form transverse channels of the condenser, where the transverse channels of the condenser are connected to the longitudinal channels of the condenser; and sealing ends of the longitudinal channels of the condenser and ends of the transverse channels of the condenser according to determined holes on the condenser that are connected to the outside.

Abstract: The present disclosure relates to telecommunication, and in particular, to a base station Radio Frequency (RF) duplexer, an RF module, and an RF system. A base station RF apparatus provided herein includes: an enclosure, an intermediate RF processing unit, and a duplexer. The enclosure is located on the duplexer; the intermediate RF processing unit is located inside a cavity enclosed by the enclosure and the duplexer, or on the duplexer; a duplexer cavity and a heat dissipation part exist on the surface of the duplexer; the opening of the duplexer cavity is opposite to or against the enclosure; the heat dissipation part is designed to dissipate heat of the intermediate RF processing unit; and the duplexer is integrally molded. The foregoing technical solution requires no external fasteners, reduces the time of production and assembly. In addition, waterproof design and shielding design are not required, and thus improves the reliability.

Abstract: Embodiments of the present invention provide a die casting aluminum alloy, including the following components in percentage by mass: 11.0% to 14.0% of silicon; 0.1% to 0.9% of manganese; 0.1% to 1.0% of magnesium; 0.3% to 1.4% of iron; less than or equal to 0.2% of copper; and aluminum and inevitable impurities. The die casting aluminum alloy has good formability, heat conductivity, and corrosion resistance, and certain mechanical properties, which can avoid problems of a low yield of die-casting fittings, burn-in caused by severe heat emission of a product, corrosion in a coastal environment, assembly difficulties caused by insufficient mechanical properties, severe deformation in a wind load condition, and the like, so as to satisfy requirements of global delivery of complex communications products.
