Abstract

The invention discloses a preparation process for a radiator good in sealing performance. The preparation process comprises the steps of preparing die casting aluminum alloy and an insert. A first annular groove is formed in the horizontal contact surface of the insert and the die casting aluminum alloy. A second annular groove is formed in the vertical contact surface of the insert and the die casting aluminum alloy. A first annular protrusion is arranged in the position, matched with the first annular groove, of the die casting aluminum alloy. A second annular protrusion is arranged in the position, matched with the second annular groove, of the die casting aluminum alloy. Preparation of the die casting aluminum alloy and the insert comprises the following steps of raw material smelting, die casting, machining, cleaning and packing, and cleaning and packing are conducted after machining is completed and the die casting aluminum alloy and the insert are qualified after being subjected to leakage testing. According to the preparation process for the radiator good in sealing performance, leakage testing is conducted under the condition of 0.2 MPa air pressure, and leakage is avoided, so that the leakage problem of a part inlaid with the insert in the aluminum alloy die casting industry is solved; the requirements for the sealing performance, the heat dissipation performance, the mechanical strength and other performances in the using process of the radiator can be met, the maintenance cost is reduced, the production efficiency is high, and the market competitiveness is very high.

Description

technical field [0001] The invention relates to the technical field of radiator manufacturing, in particular to a radiator manufacturing process with good sealing performance. Background technique [0002] The radiator is mainly composed of the main plate, water chamber, side plate, heat dissipation pipe, heat dissipation belt, etc. The leakage rate of the existing radiator reaches 40%, and the scrap rate reaches 30%, which greatly reduces the qualified rate and affects the use; so far, In the die-casting industry, there is no precedent for using aluminum alloy or red copper as inserts in die-casting products with sealing requirements, as shown in the attached figure 1 As shown, at most, aluminum alloy or copper inserts are applied to die-casting parts without sealing requirements. The difficulty of this process is that the two materials cannot be fused during the die-casting process, resulting in the die-casted parts being filled with high-pressure media in the inner cavity...
