Compensation method of modular radiator manufacturing process

Abstract

The invention relates to a compensation method of a modular radiator manufacturing process. The compensation method comprises the following steps: first, sawing an extruded section composed of a single heat storage substrate 1 and a fin 2, and then carrying out sorting and stacking before pressure closing; carrying out primary pressure closing on a plurality of the extruded sections composed of the single heat storage substrate 1 and the fin 2 to generate 2% compressive deformation; carrying out artificial aging treatment on a radiator module obtained from the primary pressure closing at the temperature of 175+ / -5 DEG C for 8 hours; then carrying out secondary pressure closing on the radiator module subjected to aging hardening to generate a 1% secondary compressive deformation and obtain a modular radiator; and finally entering a digital control processing center to obtain a finished product. In the invention, on the basis of maintaining a 'modular radiator manufacturing method', the bonding strength level of the 'inner boundary' of the substrate of the radiator is further improved through using a secondary pressure closing process compensation method, thus being capable of obtaining crack defects on the surface of the substrate of the radiator and dye penetrant nondestructive detection zero-defect results.

Description

technical field [0001] The invention relates to a preparation method of an aluminum alloy module radiator, in particular to a compensation method for a manufacturing process of a module radiator composed of a single radiator fin obtained by an extrusion method. Background technique [0002] Due to the demand for energy saving, the industrialization of frequency conversion technology and frequency converters for high-power module radiators is in the ascendant. At present, the module radiator used is composed of multiple single heat storage substrates with toothed structures on both sides and heat sinks, because of the complicated and dense "internal" in the structure of the heat storage substrate introduced by the "press-fit" manufacturing method. Interface”, the potential impact on the bonding strength of the overall module heat sink, has always been regarded as a structural element that cannot be ignored in the evaluation of thermal problem solutions in the later stage of s...

Problems solved by technology

The disadvantage is that due to the instability of the bonding strength of the inner interface of the substrate formed after "pressing", the pass rate of the coloring penetration test of the heat sink product is only 50%, resulting in potential risks during the operation of the product.
