No. 14/692,475, filed on Apr. 21, 2015, entitled “METALLIC ARTICLE AND METHOD FOR MANUFACTURING METALLIC ARTICLE”, assigned to the same assignee, which is based on and claims priority to Chinese Patent Application No. 201410169091.1 filed on Apr. 25, 2014, the contents of which are incorporated by reference herein.
FIELDThe subject matter herein generally relates to metallic articles, and particularly to a metallic article capable of dissipating heat quickly and a method for manufacturing the metallic article.
BACKGROUNDMetallic articles are used in many products, such as an electronic device. When the electronic device is in use, heat may be produced. In order to ensure the performance of the electronic device, the heat in the electronic device needs to be dissipated quickly.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The present disclosure is in relation to a metallic article can include one or more metallic elements made of a first material and a cast metallic body made of a second material. Each of the one or more metallic elements can have a first end and a second end. The cast metallic body can surround the one or more metallic elements. The cast metallic body defines a first space communicating with the first end and a second space communicating with the second end of each of the one or more metallic elements. The second material can have a heat conductivity lower than the first material.
The first mold 21 can be substantially cuboid and can include a mounting surface 210. The mounting surface 210 can be configured to couple the mold core 25 and attach to the second mold 23. The mounting surface 210 can define a first receiving groove 212 and two second receiving grooves 214 communicating with the first receiving groove 212. The second receiving grooves 214 can be positioned at opposite sides of the first receiving groove 212, respectively. The first receiving groove 212 can be positioned between the second receiving grooves 214. The second receiving grooves 214 can be substantially strip-shaped and can be parallel to each other. The first receiving groove 212 can be substantially step-shaped and configured to receive the mold core 25. The second receiving grooves 214 can be configured to receive the position tool 300.
Referring to
The second position member 33 can have a structure substantially similar to a structure of the first position member 31. The second position member 33 can also include two first fixing portions 331 parallel to each other and two second fixing portions 333 parallel to each other.
At block 101, a mould, a position tool, and a plurality of metallic elements made of a first material can be provided. The metallic element can be metallic sheet or metallic tube. Each metallic sheet or each metallic tube can include a first end and a second end opposite to the first end. In the illustrated embodiment, the one or more metallic elements are one or more copper tubes, and a number of the copper tube can be eleven. A diameter of each copper tube can be 0.3˜0.5 mm.
At block 102, a first position member of a position tool can be positioned on a first mold and a mold core of the mould. Two first fixing portions of the first position member can be received in two third receiving grooves of the mold core, respectively. Two second fixing portions of the first position member can be received in two second receiving grooves of the first core.
At block 103, the eleven copper tubes can be positioned on the first position member. Each of the first end and the second end of each copper tube can be received in a latching groove of a first latching protrusion of the first fixing portion. A middle portion of each copper tube can be supported on second position protrusions of the mold core 25. In the illustrated embodiment, the eleven copper tubes can be parallel to each other.
At block 104, a second position member can be coupled to the first position member. Positioning posts 3331 of the second position member 33 can be inserted into the positioning holes of the first position member 31. Thus, the copper tubes can be positioned in the position tool.
At block 105, a second core can be coupled to the first core, thus the mould can be closed. The second core can be positioned above the first core. A pressing surface of the second core can contact the mounting surface of the first core. Two first fixing portions and two second fixing portions of the second position member can be received in a containing groove of the second mold. A plurality of first position protrusions of the second mold and the plurality of second position protrusions can clamp the copper tubes. Thus, the copper tubes can be firmly positioned between the second mole and the mold core. A gap between adjacent first position protrusions or a gap between adjacent second position protrusions can be in communication with the die cavity.
At block 106, melt metal made of a second material can be injected into the mould through runners. The second material has a heat conductivity lower than the first material. In the illustrated embodiment, melt aluminum can be injected into the mould. In at least one embodiment, other melt metal can be injected into the mould, such as melt magnesium.
At block 107, the mould can be cooled and opened. A metallic article formed by the mould and the position tool can be get out of the mould.
At block 108, the position tool can be detached away from the metallic article.
At block 109, the metallic article can be machined. In the illustrated, the metallic article can be deburred.
In at least one embodiment, the copper tubes can be positioned in the position tool first, and then the copper tubes and the position tool can be put into the mould together.
In at least one embodiment, a number of copper tubes 400 can be one or more than one, and copper tubes 400 can be inclined with each other. A number of each of the first latching protrusion 317, the second latching protrusion 337, the first position protrusion 236, the second position protrusion 254 can be changed corresponding to a number of the copper tubes 400. When the copper tubes 400 are short, the first position protrusions 236 and the second position protrusions 254 can be omitted. The copper tubes 400 can be instead of other members made of a first metallic material. The cast metallic body 10 can be made of a second metallic material which has lower heat conductivity than the first metallic material.
