Abstract

The present invention belongs to a heat radiator, particularly to a heat radiator rolling patterns on a radiation fin. The present invention has the main technique scheme that the radiation fin is inserted on a bottom plate; the patterns are arranged on the surfaces of the radiation fin; the patterns are positioned on the two heat radiation surfaces of the radiation fin; in addition, the patterns can be formed by using a rolling way. The bottom plate can be positioned in a casing; one end of the casing is open. Installation grooves for splicing the radiation fins and V-shaped or U-shaped grooves for rolling are uniformly on the bottom plate at intervals. The use of the device can effectively enhance the radiation effect of the heat radiator.

Description

A kind of manufacture method of fin-inserted radiator

Technical field

The present invention relates to radiator, specifically a kind of on fin the annular knurl line, the method for utilizing rolling technology that fin and base plate are tightened together again.

Background technology

A lot of electronic devices and components all can produce heat when work, for guaranteeing the service life and the working condition thereof of components and parts, need to adopt radiator to dispel the heat, lower the temperature mostly, damage because of overheated to avoid electronic devices and components.Existing fin-inserted radiator mainly is made up of base plate and fin as described in the ZL97203966, because fin is plugged in the groove one by one of base plate, so be referred to as fin-inserted radiator usually.The defective of this radiator is that the smooth surface of fin is smooth, has influenced radiating effect.

Impact style is adopted in being connected of fin and base plate, because metal mobile inhomogeneous, especially when unlubricated forward extrusion, all the more so during punching press, causes the structure property of the top layer of goods and center, head and afterbody inhomogeneous; And, need mould when adopting impact style, and the difficulty of processing of mould is very high, the consume of tool and mould is also very big, and also than higher, production efficiency is low for energy consumption.

Summary of the invention

The objective of the invention is to design a kind of manufacture method of fin-inserted radiator,, avoid material, cut down the consumption of energy because of processing the improper mechanical performance that influences to improve the radiating effect of radiator.

According to design provided by the present invention, a kind of manufacture method of fin-inserted radiator comprises: fluting, and mounting groove and rolling groove are offered in even on base plate, compartment of terrain; Inserted sheet inserts blocks of fin in the mounting groove then; It is characterized in that: roll extrusion again behind inserted sheet, gelled base plate will be installed to be placed on one group of roller, again pinch roller is placed and be positioned at two rolling grooves between fin, and move along vertical limit of rolling groove, the limit roll extrusion, force the two side of rolling groove to be pushed, fin is anchored in the mounting groove to both sides.

V-shaped or " U " shape of the section of rolling groove.

Before inserted sheet, carry out annular knurl earlier, at the Surface Machining decorative pattern of fin.

Advantage of the present invention is owing to be provided with decorative pattern on two surfaces of fin, thereby has increased the contact area of fin and convective media, improves radiating efficiency, and this decorative pattern also can improve the intensity of fin simultaneously, makes that this fin is difficult to be bent.Secondly, because the present invention utilizes the fastening fin of rolling technology, problem such as the matrix of existing material is inhomogeneous when having overcome original employing Sheet Metal Forming Technology, die cost is expensive, energy consumption is high, production efficiency is low.

Description of drawings

Fig. 1 is a structure chart of the present invention.

Fig. 2 is the enlarged drawing of M among Fig. 1.

Fig. 3 be among Fig. 2 N to enlarged drawing.

Fig. 4 is the connection status figure of base plate and housing.

Fig. 5 is the rolling technology schematic diagram.

The specific embodiment

As shown in the figure: grafting fin 1 on base plate 2 has decorative pattern 5 on two radiating surfaces of fin 1.For avoiding damaging fin 1, base plate 2 can be placed in the housing 6, an end of this housing 6 must open wide, so that heat radiation.

On base plate 2 evenly and the mounting groove 3 of grafting fin 1 and " V " shape or " U " shape rolling groove 4 that roll extrusion is used are offered in the compartment of terrain so that install and fastening fin 1.

The manufacture method of this fin-inserted radiator is as follows:

A, annular knurl are at the Surface Machining decorative pattern of fin 1.Add man-hour, can utilize surperficial dapple rolling wheel that fin 1 is carried out roll extrusion and form decorative pattern.

B, fluting, on base plate 2, utilize lathe evenly, the compartment of terrain offers mounting groove 3 and rolling groove 4;

Wherein mounting groove 3 should be rectangle, so that fastening fin 1, rolling groove 4 can adopt " V " shape or " U ", carries out roll extrusion so that pinch roller embeds in the rolling groove 4.

C, inserted sheet insert blocks of fin 1 in the rectangle mounting groove 3 abreast;

D, roll extrusion, the base plate 2 that fin 1 is installed is placed on the workbench 8, one group of roller 9 is arranged below workbench 8, fin 1 up, again pinch roller 7 is placed the rolling groove 4 that is positioned at 1 of two fin, and move along vertical limit of rolling groove 4, the limit roll extrusion, force the two side of rolling groove 4 to be pushed to both sides, fin 1 is anchored in the mounting groove 3.When utilizing roller 7 roll extrusion, the active force of 7 pairs of rolling grooves 4 of roller all compares on the length of whole rolling groove evenly, and during punching press, be point-like to the extruding of cell wall, its active force can not be evenly, therefore after adopting this technology, can effectively improve the uniformity and the mechanical performance of workpiece tissue, simultaneously, need not mould during roll extrusion, thereby saved the Mould Machining expense and the running cost when producing, reduced energy consumption.
