Problems solved by technology

Condensers in the prior art mainly include wire tube type and copper tube aluminum fin type. The former is not as popular as the latter due to its large volume, high production cost, and large installation space. Although aluminum fins can reduce costs and improve corrosion resistance, their heat dissipation efficiency is far less than that of the former

Embodiment 1

[0011] A copper strip for composite fins of a condenser, the copper strip is composed of the following components by weight percentage: Mg: 0.8%; Sn: 0.8%; Ni: 0.55%; Si: 0.6%; Ag: 0.2%; P: 0.012%; the balance is Cu and 0.26% unavoidable impurities.

Embodiment 2

[0013] A copper strip for composite fins of a condenser, the copper strip is composed of the following components by weight percentage: Mg: 1%; Sn: 1.2%; Ni: 0.8%; Si: 1%; Ag: 0.35%; P: 0.02%; the balance is Cu and 0.26% unavoidable impurities.

Embodiment 3

[0015] A copper strip for composite fins of a condenser, the copper strip is composed of the following components by weight percentage: Mg: 1%; Sn: 1.3%; Ni: 0.85%; Si: 1.2%; Ag: 0.3%; P: 0.033%; the balance is Cu and unavoidable impurities; the balance is Cu and 0.25% unavoidable impurities.

[0016] While ensuring good heat dissipation performance, the above-mentioned copper strip also has better corrosion resistance and processability, and the cost is lower than that of pure copper copper strip, which is safe and environmentally friendly, and is beneficial to prolonging the service life of the condenser.

Abstract

The invention provides a copper strip for composite fins of a condenser. The copper strip is composed of the following components by weight percentage: Mg: 0.6-1.8%; Sn: 0.8-1.5%; Ni: 0.4-1.25%; Si: 0.5‑1.2%; Ag: 0.2‑0.45%; P: 0.012‑0.035%; balance Cu and unavoidable impurities. By reasonably adding other elements, the copper strip of the present invention not only ensures good heat dissipation performance, but also has better corrosion resistance and processability, and the cost is lower than that of pure copper copper strip, which is safe and environmentally friendly, and is conducive to prolonging the use of the condenser life.

Description

technical field [0001] The invention relates to a copper strip, in particular to a copper strip for composite fins of a condenser. Background technique [0002] Copper strip is widely used in machinery, electronics, chemical industry and other industries because of its good electrical and thermal conductivity and easy processing. Condensers in the prior art mainly include wire tube type and copper tube aluminum fin type. The former is not as popular as the latter due to its large volume, high production cost, and large installation space. Although aluminum fins can reduce costs and improve corrosion resistance, their heat dissipation efficiency is far less than that of the former. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a copper strip for composite fins of a condenser. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:...
