Abstract

A radiator comprises a body and a plurality of waveguide pipes. The body is provided with a plurality of radiating holes running through a lower surface and an upper surface of the body. The number of the radiating holes is the same with that of the waveguide pipes. Each waveguide pipe is a hollow pipe body made of metal material. The waveguide pipes are vertically arranged on the upper surface of the body and are in one-to-one correspondence with the radiating holes, and the waveguide pipes are mutually parallel. The radiator can dissipate heat for an electronic assembly and meanwhile, can suppress electromagnetic waves generated by the electronic assembly by utilizing the waveguide pipes thereon, thereby preventing the electromagnetic waves generated by the electronic assembly from interfering other electronic components.

Description

Radiator

Technical field

The present invention relates to a kind of radiator.

Background technology

Along with high-tech flourish, the volume of electronic building brick as CPU is tending towards microminiaturization, and closeness in unit are is also more and more higher, its usefulness constantly strengthens especially, under these factors, the gross calorific power of electronic building brick almost raises year by year, if there is no the heat that good radiating mode produces to get rid of electronic building brick, too high temperature will cause electronic building brick to produce the phenomenons such as electronics free (Thermal Runaway) and thermal stress (Thermal Stress), cause resistance to overturning to reduce, and shorten the life-span of electronic building brick itself.Usually by radiator, electronic building brick is dispelled the heat.

Traditional radiator is installed on an intrasystem electronic building brick, comprises multiple fin, for distributing the heat that electronic building brick produces.But, because existing electronic building brick incorporates various high-frequency circuit, digital circuit and analog circuit usually, electronic building brick can produce a large amount of electromagnetic waves at work, and traditional radiator because of capacitive coupling and antenna effect and then can strengthen electromagnetic radiation intensity and efficiency, make the electromagnetic interference of system (Electromagnetic Interference, EMI) problem even more serious.

Summary of the invention

In view of above content, be necessary to provide a kind of electromagnetic radiator that can effectively suppress electronic building brick to produce.

A kind of radiator, comprise a body and some waveguides, described body is provided with and somely runs through the lower surface of described body and the louvre of upper surface, the quantity of described louvre is identical with the quantity of described waveguide, each waveguide is the hollow tube that a metal material is made, these waveguides be vertical at described body upper surface and with louvre one_to_one corresponding, be parallel to each other between described waveguide.

The electromagnetic wave that above-mentioned radiator utilizes the waveguide on it to suppress described electronic building brick to produce while for an electronic building brick heat radiation, other electronic components of Electromagnetic Interference avoiding described electronic building brick to produce.

Embodiment

Below in conjunction with accompanying drawing and better embodiment, the present invention is described in further detail:

Please refer to Fig. 1 and Fig. 2, radiator of the present invention comprises a body 10 and some waveguides 20.Described radiator is used for dispelling the heat to an electronic building brick and suppressing the electromagnetic wave that described electronic building brick produces.

Described body 10 is rectangular, and a groove 13 is arranged on the central position of the lower surface 12 of described body 10, and for accommodating described electronic building brick, shape and the groove depth of described groove 13 set according to the size of described electronic building brick.Some louvres 14 to be arranged on described body 10 and to run through described body 10 lower surface 12 and upper surface 11.The quantity of described louvre 14 is identical with the quantity of described waveguide 20.

The hollow tube of each waveguide 20 all for being made up of metal material, each waveguide 20 be vertical at described body 10 upper surface 11 and with each louvre 14 one_to_one corresponding, be parallel to each other between described waveguide 20.The one end open that described waveguide 20 contacts with described body 10, the other end sealing of described waveguide 20.Described body 10 and described waveguide 20 are formed in one.

When installing and using, described radiator is arranged at the top of described electronic building brick, described electronic building brick is made to be contained in the groove 13 of the body 10 of described radiator, described radiator both other electronic building bricks of maskable produce electromagnetic wave, other electronic components of Electromagnetic Interference that described electronic building brick produces can be avoided again.Also effectively can reduce the heat that described electronic building brick produces simultaneously, and then ensure the performance of electronic building brick.
