Description
Technical field
The present invention relates to a kind of aluminium alloy heat radiator proximate matter production moulds, radiate more particularly to a kind of snail shape aluminium alloy
Section bar mold.
Background technology
The existing aluminium section bar as radiator is constituted by substrate and wing plate, and substrate is contacted with heat generating components when use
Then connection leans on wing plate to radiate, existing wing plate be all it is open be arranged side by side, wing plate dissipates heat by being in direct contact with air
It is dealt into air, so air flow property is most important to its emission efficiency, in no wind, this structure can not be formed larger
Convection current, so radiating efficiency is relatively low.This aluminium alloy extrusions is mostly produced by expressing technique, and production extrusion molding is hollow
When tubular products, aluminium alloy base will first enter multiple runners and reach extrusion, then converges and combine together by extrusion extrusion molding,
Aluminium alloy base is separated into that multichannel is invisible to improve resistance during entering multiple runners, needs higher squeeze pressure could be at
Type is influenced when multichannel aluminium alloy base converges by stable process conditions to be also susceptible to fold or crack, these are still up for skill
Art solves.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of snail shape aluminium alloy heat sink section bar molds.
The technical solution adopted by the present invention is：A kind of snail shape aluminium alloy heat sink section bar mold, it is characterised in that including main base
Plate runner, left wing's plate runner and right flank plate runner, left wing's plate runner and right flank plate runner are both connected on main substrate runner and divide
For cloth in the both sides of main substrate runner, left wing plate flow channel cross-section is vertical with main substrate flow channel cross-section, right wing plate flow channel cross-section
Vertical with main substrate flow channel cross-section, right flank plate runner is connected with snail shape wing runner, snail shape wing runner outer end and right flank plate runner
Connection, snail shape wing runner are crimped onto between left wing's plate runner and right flank plate runner, and left wing's plate runner is set far from main substrate runner end
There are overhead kick runner, snail shape wing runner to be externally provided with buckle runner, buckles and possess gap, the extrusion pin snail shape wing between runner and overhead kick runner
Collapsing buckle can be fastened in overhead kick.
Further, it is respectively equipped with the circumferential buckle runner for possessing spacing on the adjacent surface of the snail shape wing runner curling,
The extrusion pin snail shape wing collapses buckle and can fasten.
Further, the snail shape wing runner is equipped with the protrusion that is longitudinally extended, shape on the respective protrusions extrusion pin snail shape wing
At thinning area.
Further, snail shape wing runner inner edge is connected with stem runner.
It is non-occluded configuration when aluminium alloy extrusions of the present invention squeezes out, does not have to setting runner and exported to extrusion die, needed
Squeeze pressure is smaller, it would be desirable to be able to which amount consumption is smaller, and aluminium material surface fold and crack occurrence probability are small, and extrusion profile only needs when use
Apply pressure engaging.In use, main substrate absorbs the heat of component and transfers heat to left wing plate, right wing plate and snail
The shape wing, heating part transfer heat to the air of surrounding simultaneously, and heat dissipation area is big, main substrate, left wing plate, right wing plate and snail shape
The wing surrounds longitudinal gas channel, and the air heats in air flue rise to be flowed out by upper opening, and normal temperature air enters supplement by air flue under shed,
A stronger convection current can be formed, radiating efficiency is improved.
Description of the drawings
Fig. 1 is overall structure diagram of the embodiment of the present invention.
Specific implementation mode
The embodiment of the present invention is as shown in Figure 1, the snail shape aluminium alloy heat sink section bar mold is equipped with main substrate runner 1, left wing plate
Runner 2 and right flank plate runner 3, for being extruded into main substrate 4, left wing plate 5 and right wing plate 6, left wing's plate runner and right wing plate stream
Road is both connected on main substrate runner and is distributed in the both sides of main substrate runner, and left wing plate flow channel cross-section is horizontal with main substrate runner
Section is vertical, and right wing plate flow channel cross-section is vertical with main substrate flow channel cross-section, and right flank plate runner is connected with snail shape wing runner 7,
For being extruded into the snail shape wing 8, snail shape wing runner outer end is connect with right flank plate runner, and snail shape wing runner is crimped onto left wing's plate runner
Between right flank plate runner, left wing's plate runner is equipped with overhead kick runner 9 far from main substrate runner end, and snail shape wing runner is externally provided with buckle
Runner 10 buckles and possesses gap between runner and overhead kick runner, and the extrusion pin snail shape wing collapses buckle 11 and can be fastened in overhead kick 12,
Main substrate, left wing plate, right wing plate and the snail shape wing surround longitudinal gas channel 13, and connection thermal conductivity is good, and heat dissipation area is big；Snail shape wing runner
The circumferential buckle runner 14 for possessing spacing is respectively equipped on the adjacent surface of curling, the extrusion pin snail shape wing collapses buckle 18 and can detain
It closes, it is ensured that the stability of structure, and several independent air flues are separated, form different convection spaces；Snail shape wing runner inner edge connects
It is connected to stem runner 17, the stem 15 being extruded into can assist being connected to carrier, improve structural stability.
It is non-occluded configuration when aluminium alloy extrusions of the present invention squeezes out, does not have to setting runner and exported to extrusion die, needed
Squeeze pressure is smaller, it would be desirable to be able to which amount consumption is smaller, and aluminium material surface fold and crack occurrence probability are small, and extrusion profile only needs when use
Apply pressure engaging.In use, main substrate absorbs the heat of component and transfers heat to left wing plate, right wing plate and snail
The shape wing, heating part transfer heat to the air of surrounding simultaneously, and heat dissipation area is big, main substrate, left wing plate, right wing plate and snail shape
The wing surrounds longitudinal gas channel, and the air heats in air flue rise to be flowed out by upper opening, and normal temperature air enters supplement by air flue under shed,
A stronger convection current can be formed, radiating efficiency is improved.
It is only present pre-ferred embodiments in summary, all equivalent modifications done according to the application and prior art addition are equal
It is considered as the technology of the present invention scope.
