Background technology
Existing mobile phone heat abstractor includes base and is connected to the top part of the base top, wherein, base and top Part is Al-alloy parts, due to the bad radiating efficiency for having had a strong impact on mobile phone heat abstractor of the thermal conductivity factor of aluminium alloy.Meanwhile Base and top part are connected to each other by heat conduction glue bond, and heat-conducting glue can play a part of heat transfer, but make for a long time Occur that aging causes still to have gap between base and top part after, have a strong impact on the radiating effect of mobile phone heat abstractor Fruit;Also, the processing cost of mobile phone heat abstractor is also greatly increased using heat-conducting glue.
The content of the invention
It is an object of the invention to provide a kind of mobile phone heat abstractor and its processing method, the radiating of the mobile phone heat abstractor is imitated Fruit is good, while the process steps of the mobile phone heat abstractor are simple and production cost is relatively low.
To achieve these goals, the invention provides a kind of mobile phone heat abstractor, mobile phone heat abstractor include base and Be connected to the top part of base top, top part includes being used for pedestal be connected with base, the bottom of pedestal formed with neck with One in fixture block, is correspondingly formed with the other of neck and fixture block at the top of base, in fixture block insertion neck, to cause base Seat and base are connected to each other, also, top part is copper alloy part, and base is Al-alloy parts.
Preferably, fixture block includes the base portion for being connected to pedestal or base and base portion protrudes the wedge-shaped block portion to be formed, along every The bearing of trend of individual base portion, it is spaced formed with multiple wedge-shaped block portions, and neck is formed as with the shape being engaged with fixture block.
Preferably, pedestal and base perpendicular to the cross section in base and the overlapping direction of top part be rectangle;Base portion edge The edge of pedestal or base extends, and fixture block includes being formed at two wedge-shaped block portions at the both ends of base portion and positioned at base portion Middle part at least one wedge-shaped block portion.
Preferably, at pedestal or two edges relative to each other of base, it is respectively formed with a base portion.
Preferably, fixture block is formed on top part, and neck is formed on base.
Preferably, top part also includes being formed at multiple fin at the top of pedestal.
Present invention also offers a kind of processing method of mobile phone heat abstractor, mobile phone heat abstractor radiates for above-mentioned mobile phone Device, processing method include:
Step 1:Copper alloy blank material is machined to form top part;
Step 2:By the top part according to the pedestal of the top part bottom towards the inner chamber of die casting bottom Mode be arranged in the inner chamber of the die casting, and inject into the inner chamber of the die casting aluminium alloy liquid to causing The aluminium alloy liquid coats the bottom of the pedestal;
Step 3:The aluminium alloy liquid is set to be cooled to solid-state to form mobile phone heat abstractor.
Preferably, copper alloy blank material is heated to 950-1000 DEG C, top part blank material is formed by extrusion forming, then simultaneously The top part blank material is machined out to form the top part.
Preferably, also include in step 1:Multiple fin are formed by machining mode on the top of pedestal.
Pass through above-mentioned technical proposal, the present invention is by machining copper alloy blank material to form top part;Then by top part By top part pedestal bottom towards the inner chamber of die casting bottom in the way of be arranged in the inner chamber of die casting, and Aluminium alloy liquid is injected into the inner chamber of die casting to the bottom for causing aluminium alloy liquid cladding pedestal;Finally close the aluminium Golden liquid cooling is to solid-state to form mobile phone heat abstractor.The mobile phone heat abstractor being process by such processing method, Base and top part are entirely by the aluminium alloy of melting and then are coated on the bottom of pedestal and realize the nothing of base and top part Seam connection, so as to improve the heat transfer efficiency of the mobile phone heat abstractor.Avoided in the processing method using heat-conducting glue, not only Cost is reduced, while completely avoid the hair for the situation for causing occur gap between base and top part because of the aging of heat-conducting glue It is raw.In addition, top part is copper alloy part, base is Al-alloy parts, and difference is that aluminium closes with top part and base in the prior art Golden part, the advantages of being substantially better than the thermal conductivity factor of Al-alloy parts using the thermal conductivity factor of copper alloy, so as to further improve mobile phone The radiating effect of heat abstractor.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
