Description
Technical field
This utility model is related to radiator field, particularly a kind of heat sink assembly.
Background technology
Existing heat abstractor, those heat abstractors typically all include a radiator body, the side of described radiator body
Integrally formed with many fins for radiating on wall, although those fins can play the effect of radiating, due to those
The surface area of fin typically ratio is larger, and the side that heat is contacted with radiator body from fin is transferred to other side to be needed relatively
The long time, thus heat can not distribute readily through the whole surface of full wafer fin, radiating rate is relatively slow,
Thus have impact on the integral heat sink effect of those heat abstractors, and then make the radiating effect of those heat abstractors can not be well
Meet the demand of people, for solving to improve the heat-sinking capability of radiator, Chinese utility model patent（The patent No.
CN201520373198.8）Disclose a kind of radiating subassembly, being formed using the radiating fin combination of U-shaped heat pipe and two groups being capable of array
Combination forms the radiating subassembly of radiator, but in this radiating subassembly, forms one substantially wide between two groups of fin
Passage, its cross-ventilation effect is bad, reduces the radiating efficiency of radiator.
Content of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of heat sink assembly.
This utility model solves its technical problem and be employed technical scheme comprise that：
A kind of heat sink assembly, the heat-conducting piece including a U-shape structure and two groups are separately fixed at the heat-conducting piece two of U-shape structure
Fin on arm, two groups of fin is arranged substantially on same plane, formation flow-guiding channel between two groups of fin, two groups
The top of the relative side of fin or bottom or upper and lower setting jagged so that flow-guiding channel top or bottom or on
The bell-mouth structure of air gradually expanding is formed at portion and bottom.
The upper and lower setting of the relative side of two groups of fin jagged so that flow-guiding channel upper and lower is formed
The bell-mouth structure of air gradually expanding.
Described breach is a chamfering or fillet structure.
The through hole that the arm of heat-conducting piece can be supplied to penetrate is offered on described fin.
Described fin is integrally formed by extruded aluminium, and described through hole is the circular hole of the complete closure of a circumference.
It is interference fit between described heat-conducting piece and through hole.
Coordinate for gap between described heat-conducting piece and through hole and between heat-conducting piece and through hole, be provided with heat-conducting daub.

Described heat-conducting piece is a heat pipe.
The beneficial effects of the utility model are：A kind of heat sink assembly, the heat-conducting piece including a U-shape structure and two groups of difference
It is fixed on the fin in the heat-conducting piece two-arm of U-shape structure, two groups of fin is arranged substantially on same plane, two groups of radiatings
Form flow-guiding channel, the relative top of side of two groups of fin or bottom or upper and lower setting are jagged, make between piece
Obtain the bell-mouth structure of air that flow-guiding channel top or bottom or upper and lower formation gradually expand, strengthen the air pair of flow-guiding channel
Stream effect, urgent fin and the efficiency of air heat-exchange, improve overall radiating effect, can also mitigate light fixture weight simultaneously.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is decomposing schematic representation of the present utility model；
Fig. 3 is front schematic view of the present utility model.
Specific embodiment
Referring to figs. 1 to Fig. 3, Fig. 1 to Fig. 3 is the structural representation of one specific embodiment of this utility model, as illustrated,
A kind of heat sink assembly, the heat-conducting piece 1 including a U-shape structure and two groups are separately fixed in heat-conducting piece 1 two-arm of U-shape structure
Fin 2, two groups of fin 2 is arranged substantially on same plane, during use, multigroup heat sink assembly array combination, make
Form flow-guiding channel 3 between two groups of fin 2, the relative top of side of two groups of fin 2 or bottom or upper and lower
Setting is jagged so that the bell-mouth structure of air gradually expanding is formed at flow-guiding channel 3 top or bottom or upper and lower, and enhancing is led
The cross-ventilation effect of circulation road, urgent fin and the efficiency of air heat-exchange, improve overall radiating effect, simultaneously acceptable
Mitigate light fixture weight.
Preferably, the upper and lower setting of the relative side of two groups of fin 2 jagged so that flow-guiding channel 3 top
Form, with bottom, the bell-mouth structure of air gradually expanding, strengthen intake and the exhaust air rate of flow-guiding channel 3 simultaneously.
Preferably, described fin 2 is a rectangular configuration, and described breach is formed by a chamfering or fillet structure.
Preferably, described heat-conducting piece 1 is a heat pipe, described fin 2 offers the arm of heat-conducting piece 1 can be supplied to penetrate
Through hole 21 it is preferable that between described heat-conducting piece 1 and through hole 21 be interference fit.Due between heat-conducting piece 1 and through hole 21 being
It is full of cooperation, is directly contact therefore between heat-conducting piece 1 and through hole 21, therefore heat can be transferred directly on fin 20 not
Need to transmit by air, accelerate heat transfer speed.Certainly can also be gap between described heat-conducting piece 1 and described through hole 21
Cooperation, but now can fill heat-conducting daub between heat-conducting piece 1 and through hole 21, can also be greatly by this heat-conducting daub
Improve heat and be transferred to the speed fin 20 from heat-conducting piece 1.In addition, except filling heat-conducting piece 1 and leading to using heat-conducting daub
