Abstract

The invention relates to a heat dissipation frame manufacturing method and products thereof. The heat dissipation frame manufacturing method comprises the following steps: firstly extruding an aluminum product into a cooling fin prototype; after measuring the cooling fin prototype according to needed dimensions, carrying out a local punching shear on a position to bend of the cooling fin prototype to form a plurality of punching shear gaps; bending the cooling fin prototype at the position of the punching shear gaps and forming a plurality of bending angles in a mutual butt joint mode; and fixedly jointing the butt joint positions of the punching shear gaps and the head and tail butt joint positions of the bended cooling fin to form a frame. Therefore, an extruding type cooling fin formed through a punching shear and bending can effectively reduce the procedures and save materials and reduce the cost of work hours and reach the aims of improving the heat conduction performance and lowering the manufacturing cost.

Description

Heat-dissipating frame manufacture method and goods thereof

Technical field

The present invention relates to a kind of heat-dissipating frame manufacture method and goods thereof, be specifically related to a kind of radiator structure that is applied to liquid crystal display backlight module.

Background technology

The multiple advantages such as that liquid crystal display has is slim, light weight, low radiation and low power consumption, make it within the short several years, just replace traditional crt display fully and become main product on the information market, but because display panels (LCD panel) itself does not have luminous function, therefore need to be in display panels rear configuration backlight module in order to provide display panels needed light source.

And traditional backlight module uses CCFL (CCFL), and it has mercurous shortcoming, and does not have an advantage compared to light emitting diode (LED) in reaction speed, monochromaticjty, volume and power consumption; Therefore, along with liquid crystal display continues towards large scale and lightening development trend, also so that light emitting diode replaces the main backlight that CCFL becomes liquid crystal display of new generation gradually.

Yet, although light emitting diode has that volume is little, brightness is high and the advantage such as low power consumption, but, the heat energy that produces in the process of electric energy conversion luminous energy can affect the problems such as its luminous efficacy and then generation colour cast, so, how by heat dissipation technology to avoid high temperature for the impact in production reliability and life-span, be the problem that many dealers institute wish solves.

See also shown in Figure 1, it is the backlight module heat abstractor 1 of a liquid crystal display, it comprises a plurality of light-emitting diode (LED) modules 11, a plurality of fin 12 and a metal backing 13, described light-emitting diode (LED) module 11 is individually fixed on the fin 12, again fin 12 is fixed on the metal backing 13, and then the heat energy that produces when making light-emitting diode (LED) module 11 work can conduct to metal backing 13 by fin 12, and further discharge outside the liquid crystal display, very not convenient during its assembling, and described fin 12 is the contact conduction with metal backing 13, and its heat conduction efficiency is limited; Moreover the fin 12 of this type radiator structure and metal backing 13 must be offered respectively mould up to specification for the liquid crystal display of different size, and it can cause manufacturing cost to increase, and necessity of improvement is arranged in fact.

Summary of the invention

The object of the present invention is to provide a kind of heat-dissipating frame manufacture method and goods thereof, in order to overcome the existing shortcoming that the backlight module heat radiation structure heat conduction efficiency is limited and cost of manufacture is higher.

In order to reach described purpose, heat-dissipating frame manufacture method of the present invention the steps include: aluminium is extruded into just type of fin; After the measurement of required size specification, carry out local punching at the long limit of the first type of fin wish bending part and form a plurality of punching breach, the first type of fin is formed a plurality of bendings angle in the bending of punching breach and mutual the docking, the first type initial and end joint of the fin after punching breach joint and the bending is engaged fix formation one framework again.

Further, the fixing mode of described joint can adopt stamping riveting method or chimeric method, wherein, the stamping riveting method is that the first type initial and end joint of the fin after described punching breach joint and bending has dug respectively a plurality of perforation, and by the number riveting sheet, it is provided with the flange of the described perforation of a plurality of correspondences, makes it be riveting in described perforation with impact style, and then formation one framework of combining closely.

Further, chimeric method then is that the local punching of described punching breach is mutually corresponding dovetail seat and dovetail groove, and in the just initial and end end punching of type of fin dovetail seat and dovetail groove are arranged simultaneously, more corresponding dovetail seat and dovetail groove are docked respectively chimeric rear formation one framework.

Heat-dissipating frame goods of the present invention include a framework and a plurality of riveting sheet, described framework is to be formed by the just type bending of fin that aluminium extrudes, described framework has a plurality of bendings angle, inboard, described bending angle has respectively a punching breach, and described punching breach joint and described fin just type initial and end joint have dug respectively a plurality of perforation; Described riveting sheet is provided with the flange of the described perforation of a plurality of correspondences, and its punch riveting is combined closely it and is integral in described perforation.

In sum, the present invention has following advantages:

1. the heat-dissipating frame according to the moulding of manufacture method of the present invention institute is formed in one, and can save procedure of processing and expending of reducing work hours, and can effectively overcome the shortcoming that affects thermal energy conduction usefulness after the backboard of existing backlight module and fin engage.

2. heat-dissipating frame of the present invention is to squeeze the machine-shaping of type mode, it has the not limited advantage of length, be applicable to the backlight module of all size, as long as measure rear in appropriate location punching breach according to the demand dimensions, can stamping riveting or chimeric moulding after bending, owing to no longer need to offer one by one mould according to different size, so can significantly reduce manufacturing cost, have splendid industrial applicability.
