Abstract

The invention discloses a production technology of a heat pipe aluminum alloy heat dissipater. The production technology comprises the steps that 1, a heating pipe groove and a locating convex body are machined mechanically; 2, electroplating is carried out; 3, welding paste is brushed, and assembly is carried out; 4, vacuum desorption is carried out; 5, welding is carried out; 6, washing is carried out; 7, checking is carried out; and 8, plane machining is carried out. The production technology is simple and easy to achieve, and the problems that in the traditional welding process, due to existence of a large number of air bubbles, as a result, a large quantity of cavities exist in a welding layer, a heat pipe floats up, the performance of a product is lowered, and even the product is scrapped are solved.

Description

technical field [0001] The invention relates to a production process of a heat sink, in particular to a production process of a heat pipe-aluminum alloy heat sink. Background technique [0002] The thermal conductivity of heat pipes is more than 100 times that of ordinary metals. Its excellent thermal conductivity makes heat pipe radiators made of heat pipes more and more widely used in electronic equipment. Heat pipe heat dissipation technology has become one of the important technologies for efficient heat dissipation of electronic equipment. one. Because the aluminum alloy has the advantages of low density and good processability, the heat pipe-aluminum alloy radiator has become the most popular radiator. At present, the heat pipe-aluminum alloy radiator often adopts a low-temperature brazing process, that is, the heat pipe is buried in the heat pipe groove, and then coated with low-temperature brazing material for welding. However, the current process is complex and th...
