Description

The manufacture craft of heat radiation module

Technical field

The invention belongs to the laptop heat-dissipation technical field, be specifically related to a kind of manufacture craft of heat radiation module of notebook computer.

Background technology

Along with the fast development of electronic industry, the high speed of electronic component, high frequency and integrated its thermal value that makes increase severely, and therefore, heat radiation has become the problem that dealer institute emphasis is considered.

Heat radiation module (Thermal Module), as its name suggests, be to apply to the module group unit that system/device/apparatus etc. is made heat transmission, and this patent refers to use the heat abstractors (Cooler) such as the desktop computer of heat pipe and projector.Inner space characteristic because of notebook computer, palpus employing RHE(Remote Heat Exchanger) heat interchange concept solves the problem of system used heat, therefore, the heat abstractor of notebook computer consists of heat conduction section, radiating segment and the large main part of elastic force locked mechanism three and attached subsides part basically, wherein, heat pipe is shouldered quick heat conducting role in the heat conduction section, fan provides forced convertion required air-flow for radiating segment, is respectively the technological core of heat conduction section and radiating segment.

Convention is as can be known, and area of dissipation is larger, and conduction efficiency is higher, just distribute heat more effectively.At present common heat radiation module is the thin heat-dissipating aluminium plate measure-alike with it that be sticked on components and parts to be dispelled the heat, on this aluminium sheet, has the copper conductor tube of a high thermal conductivity, and in the other end of copper conductor tube, some heat radiator are set, this heat radiator is connected to the computer side, from then on heat is shed outside computer, and by radiator fan, these some heat radiator are forced to heat interchange, improve radiating effect.

Yet, but for this heat radiation module, also form at present the manufacture craft of the ripe streamline production of a cover, cause existing method for making at random, without chapters and sections, be not suitable for modern industrial flow-line operation.

Summary of the invention

The invention provides a kind of manufacture craft of the module that dispels the heat, intactly formed the making of this heat radiation module, processing step is reasonable, and scientific and effective, and human-based management has improved the make efficiency of heat radiation module, simultaneously, has realized the production line operation.

In order to reach above purpose, the technical scheme of employing: a kind of manufacture craft of the module that dispels the heat, it comprises the following steps,

1), adopt the wire mark web plate to carry out wire mark to copper billet, and after the die casting in the module that will dispel the heat, riveted spare, fin put lead-free tin cream respectively, by in the baking tool of packing into after heat pipe, die casting, riveted spare, over cap assembling, sealed CPU, and with after dovetail clip clamping fin Overwelding and rewelding furnace, cool furnace, half product appearance of testing;

2), will toast and semi-manufacture temperature drop performance test after the assay was approved, fan is sealed, on die casting and riveted spare, carry out the E type and buckle fastening, carry out being placed with of insulating tape, Product labelling, automatic scanning, after being placed with of buffering foam, supplies again, carry out hole bit parallel degree check, the different sound test of fan, then heat-conducting cream wire mark, touch-up paint is inspection eventually, and certified products are packed and are got product.

Beneficial effect of the present invention: intactly formed the making of heat radiation module, processing step is reasonable, and scientific and effective, and human-based management has improved the make efficiency of heat radiation module, simultaneously, has realized the production line operation, has improved production efficiency.

Embodiment

In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.

A kind of manufacture craft of the module that dispels the heat comprises the following steps,

1), adopt the wire mark web plate to carry out the copper billet wire mark, after die casting, riveted spare, fin in the heat radiation module are put to lead-free tin cream respectively, again assembling heat conductivity pipe, die casting, riveted spare, over cap pack into the baking tool in, and sealed CPU, with after dovetail clip clamping fin Overwelding and rewelding furnace, cool furnace, check semi-manufacture outward appearance;

2) the semi-manufacture temperature drop performance test that, will toast and be up to the standards, fan is sealed, and on die casting and riveted spare, carries out the E type and fasten, and then carries out insulating tape respectively, Product labelling is placed with, automatic scanning, being placed with of buffering foam, supplies, then carry out hole bit parallel degree check, the different sound test of fan, after the heat-conducting cream wire mark, touch-up paint, inspection eventually, the certified products packing is finished product.

Specifically, as shown in Figure 1, the manufacture craft of this heat radiation module comprises:
