example 1

[0036] The selected aluminum tube grade is 1060 industrial pure aluminum, and its composition (weight percentage) is Si: 0.15%, Fe: 0.18%, Cu: 0.02%, Zn: 0.02%, Mn: 0.01%, Mg: 0.01%, and the rest is Al. The cross section of the aluminum tube is circular, the outer diameter is 8mm, and the wall thickness is 1mm. The base material of the aluminum cooling plate is ZL305 aluminum alloy for industrial use, and its composition is (percentage by weight) Mg: 8.20%, Zn: 1.21%, Ti: 0.15%, Fe: 0.2%, Si: 0.15%, Ni: 0.05%, Mn : 0.01%, Cu: 0.01%, and the rest is Al. The liquidus line of ZL305 alloy is 610°C.

[0037] The specific process is as follows:

[0038] 1) Aluminum tube preparation and forming

[0039] Bending the 1060 aluminum tube on the master form according to the required shape. When bending, the bending radius is required to be greater than 2 times the diameter of the aluminum tube to reduce wrinkling or cracking of the aluminum tube. After the bending is completed, poli...

[0046] The selected aluminum tube grade is 6061, and its composition (weight percentage) is Mg: 1.1%, Si: 0.62%, Fe: 0.65%, Cu: 0.29%, Mn: 0.13%, Zn: 0.22%, Cr: 0.10% , Ti: 0.15%, the rest is Al. The cross-section of the aluminum tube is circular, with an outer diameter of 6 mm and a wall thickness of 1 mm. The base material of the aluminum cooling plate is ZL101A aluminum alloy for industrial use, and its composition is (weight percent): Si: 6.93%, Mg: 0.38%, Ti: 0.15%, Fe: 0.17%, Ni: 0.05%, Zn: 0.01%, Cu : 0.01%, Mn: 0.01%, Sn: 0.01%, and the rest is Al. The liquidus and solidus temperatures of the ZL101A alloy are 615°C and 560°C, respectively.

[0047] The specific process is as follows:

[0048] 1) Aluminum tube preparation and forming

[0049] The aluminum tube is preheated to 100°C in a resistance furnace, and the wood alloy (its composition weight percentage is Bi: 50%, Pb: 25%, Sn: 12.5%, Cd: 12.5%) is melted in a water bath at 100°C Finally, the Wood alloy is po...

Abstract

The invention relates to a composite casting method of an aluminum cooling plate, belonging to the field of metal materials. The composite casting method comprises the following steps: fixing industrial pure aluminum or an aluminum alloy pipe which is used as a cooling liquid passageway in a mold cavity; and then fully filling liquid or semi-solid aluminum alloy melt in the mold cavity and coagulating, so as to prepare the aluminum cooling plate. By using the composite casting method, the problem that when the aluminum alloy is casted in an aluminum tube, a casting is wasted because the aluminum tube is melted and deformed is solved, thereby achieving the near-net forming of the aluminum cooling plate, reducing the consumption of materials for subsequent processing procedures and improving the production efficiency. Because the aluminum tube and an aluminum cooling plate substrate are made of aluminum materials, thereby eliminating an electrochemical corrosion phenomenon; and the aluminum cooling plate can be integrally retrained or recycled, thereby reducing the waste of the material and lowering the production cost. The total density of the casting is the same as that of an aluminum casting, thus the casting can be applied to the fields of aviation, ships and the like which have strict requirements on the weights of parts.

Description

technical field [0001] The invention relates to a compound casting method for an aluminum cooling plate, which belongs to the field of metal materials, in particular to a cooling liquid channel for removing heat generated by electronic devices, electronic modules, integrated circuit boards and circuits, electronic systems, etc. A method of manufacturing an aluminum cooling plate. Background technique [0002] With the development of science and technology, electronic devices are used more and more widely, but electronic devices will generate a lot of heat when they work, so electronic devices need to be cooled and dissipated to prevent excessive heat accumulation from shortening their life and causing them to fail to work or fail. The main cooling methods currently used are liquid cooling and air cooling, but as the integration of electronic devices and modules becomes higher and higher, the calorific value per unit area (or volume) is also increasing, which is limited by th...
