Abstract
A forming structure of radiating fins consists of a thermotube and radiating fins, which are all made of metal. The radiating fins are provided with perforated holes which extend the copulas arranged on the side of the perforated holes, and the upper edges of the perforated holes are provided with the stoma of minor caliber in addition, the radiating fins are fixed around the thermotubes through the perforated holes and the copulas, after that a third metal such as sliver, tin and copper wires is fused with radiating fins and the thermotube through the method of hot melt. The structure forms a compact connection between the radiating fins and the thermotube, which has no thermoresistance at the connection, so that the device has a better heat guide efficiency.
Description
The utility model relates to a kind of radiating fin shaped structure, refers to a kind of radiating fin and heat pipe can being combined closely especially, no interface thermal resistance, and the better heat abstractor of heat conduction efficiency.
The existing hot pipe technique that utilizes of known heat abstractor, inside heat pipe system is provided with suitable capillary structure (wick structure), capillarity by capillary structure, can be convenient to the transmission of working fluid (working fluid) in the heat pipe, heat pipe can be connected on the heat generating components such as main frame central interior processor (CPU) or other high temperature chip, so that utilize heat pipe that the thermal conductance on the heat generating component is gone out, can be in order to assist heat radiation, can effectively make heat generating component (as central processing unit) energy operate as normal.
As shown in Figure 1, three-dimensional exploded view for a kind of known radiating fin and heat pipe shaped structure, this radiating fin and heat pipe shaped structure are combined by heat pipe la and radiating fin 2a, this radiating fin 2a borrows perforation 3a and junction surface 4a to be socketed on this heat pipe 1a, in order to strengthen the radiating effect of heat pipe 1a, can go up the some radiating fin 2a of socket to increase area of dissipation in heat pipe 1a, because this radiating fin 2a only is fixed on the heat pipe 1a so that the tight fit mode is sheathed, or glue together with heat-conducting glue again between radiating fin 2a and heat pipe 1a, its closed intensity is poor, and can increase the interface thermal resistance, so heat conduction efficiency is very not good.
On reality is used, obviously there are shortcomings such as inconvenience in above-mentioned known heat abstractor, and remain to be improved.
Main purpose of the present utility model, be to provide a kind of radiating fin shaped structure, it is that heat pipe and radiating fin is made with the preferable copper of ductility and heat conductivity, and behind hot melt, radiating fin and heat pipe are combined as a whole with the pore that silver, tin or copper wire grade in an imperial examination three metals are inserted the perforation upper limb, can have preferable adaptation in the mode that is tightly fixed on heat pipe by more known radiating fin, and do not borrow the heat-conducting glue gummed between the utility model radiating fin and heat pipe, no interface thermal resistance, heat conduction efficiency is better.
A kind of radiating fin shaped structure provided by the utility model, it comprises:
One heat pipe; And
At least the above metal fin of a slice, this fin is provided with perforation, side in the perforation is extended the junction surface, and in the perforation upper limb be provided with the less pore of a bore, this fin borehole jack that wears long is connected on this heat pipe, comprise that also a wire is placed in the pore of radiating fin upper limb, with the wire of hot melt heat pipe is engaged with radiating fin and become one.
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, so that further understand the utility model feature and technology contents, yet appended graphic reference and the explanation usefulness of only providing not is to be used for the utility model is limited.Wherein:
Fig. 1 is the three-dimensional exploded view of known radiating fin and heat pipe shaped structure;
Fig. 2 is a three-dimensional exploded view of the present utility model;
Fig. 3 is a three-dimensional combination figure of the present utility model;
Fig. 4 is the A portion enlarged drawing of the utility model Fig. 3;
Fig. 4 A is the wire fusion back schematic diagram of the utility model Fig. 4;
Fig. 5 is a profile of the present utility model.
See also Fig. 2 and Fig. 3, be respectively three-dimensional exploded view of the present utility model and constitutional diagram, the utility model provides a kind of radiating fin shaped structure, it includes a heat pipe 1, radiating fin 2 and wire 5, wherein heat pipe 1 becomes with copper, this heat pipe 1 inside is provided with suitable capillary structure and working fluid (figure slightly), by the capillarity of capillary structure, can be convenient to the transmission of working fluid in the heat pipe 1.Radiating fin 2 becomes with copper, respectively be provided with a perforation 3 on the radiating fin 2, the internal diameter of this perforation 3 is slightly larger than the external diameter of heat pipe 1, and extend one and be circular junction surface 4 in perforation 3 edges, this junction surface 4 protrudes from radiating fin 2 one sides, the upper limb of this perforation 3 is provided with a pore 6, pore 6 can be for inserting wire 5, the big I of this pore 6 decides its size according to the caliber variation of heat pipe 1, and the size of this pore 6 also can determine to insert the quantity of wire 5, these radiating fins 2 borrow perforation 3 and junction surface 4 spacer sleeves to be connected on the heat pipe 1, then wire 5 is placed in the pore 6 of radiating fin 2 perforation upper limbs, utilizes hot melting way that radiating fin 2 and heat pipe 1 are combined into one again.
As shown in Figure 5, be profile of the present utility model, can find out that wire 5 links together radiating fin 2 and heat pipe 1 closely, constitutes a no interface thermal resistance, the radiating fin shaped structure that heat conduction efficiency is good after fusion.
The utility model in use, heat pipe 1 one ends can be connected in a heat-conducting block (figure slightly), 1 of this heat-conducting block and heat pipe also utilize sinter bonded, be affixed on the heat generating components such as the central processing unit (CPU) of main frame inside or other high temperature chip with this heat-conducting block again, so that utilize heat pipe 1 that the thermal conductance on the heat generating component is gone out, and utilize this radiating fin 2 to increase area of dissipation, to reach preferable radiating effect.
The utility model is mainly made with the preferable copper of ductility and conductibility with heat pipe 1 and radiating fin 2, the ductility of copper and heat conductivity are all good than aluminium, and the thermal resistance of copper is also low than aluminium, this heat pipe 1 is to borrow silver, tin or copper wire grade in an imperial examination three metal fevers to be melt into to be formed in one with radiating fin 2, can be fixed on the heat pipe 1 in friction tight mode by more known radiating fin 2, has preferable adaptation, can be described as almost completely driving fit, and 1 of the utility model radiating fin 2 and heat pipe do not need to glue together with heat-conducting glue, no interface thermal resistance, heat conduction efficiency is better.
In sum, the utility model is real in improving known heat abstractor, and it is poor to solve between fin and heat pipe adaptation, interface thermal resistance height, and the rare utility model product of problem such as heat conduction efficiency is low has novelty, creativeness and practicality.
