摘要： 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. In this production method, the longitudinal channels of the condenser are formed by squeezing on the substrate, and the transverse channels are formed by drilling holes on the substrate. In this way, the longitudinal channels and the transverse channels are integrated and do not need to be connected in a welding manner. Therefore, no welding joints exist between the formed longitudinal channels and transverse channels of the condenser, so that sealing performance, strength, or the like, of the condenser can be ensured with relatively high operating reliability. The present invention further discloses a gravity loop heat pipe heat sink and a method for producing the gravity loop heat pipe heat sink.

摘要： Embodiments of the present invention provide a die casting aluminum alloy, including constituents with the following mass percentages: silicon: 4.0% to 10.0%; magnesium: 0.2% to 1.0%; copper: ≤0.1 %; manganese: ≤0.1 %; zinc: ≤0.1 %; ferrum: ≤1.3%; titanium: ≤0.2%; inevitable impurities: ≤0.15%; and the rest: aluminum. The die casting aluminum alloy has a high heat-conducting property, good formability, high corrosion resistance, and a good mechanical property. This can resolve a prior-art problem that forming and heat dissipation requirements of a communications product with a complex structure, high heat flux density, and large power cannot be met at the same time because it is difficult for a die casting aluminum alloy to have both a high heat-conducting property and good formability. The embodiments of the present invention further provide a production method of the die casting aluminum alloy and a communications product.
