Abstract
The invention discloses a kind of heat spreader structures, including upper spacer, lower clapboard, fin, left strip of paper used for sealing and right strip of paper used for sealing, the fin is arranged between upper spacer and lower clapboard, the left strip of paper used for sealing and right strip of paper used for sealing are respectively connected between upper spacer and lower clapboard left and right ends, and the fin uses wave rectangular groove structure.By the above-mentioned means, heat spreader structures provided by the invention, the disadvantage for overcoming prior art radiating efficiency not high, after fin by wave rectangular groove structure, the cross-ventilation that can be formed causes air more to come into full contact with, efficiently quickly heat exchange is realized, heat transfer and radiating efficiency are improved.
Description
Technical field
The present invention relates to the field of electric elements more particularly to a kind of heat spreader structures.
Background technology
With the development of electronic technology, powerful device is also to small, work efficiency is high etc. development, chip conduct
The core component of powerful device and the pyrotoxin of powerful device internal core, working efficiency determine high-power set
Standby working efficiency, quality and product hierarchy solves the problems, such as so the heat dissipation of chip is the primary of product design.It is domestic at present big
Power power electronics industry high power radiation device, mainly slots on aluminum base plate, is pressed into multiple plate fins to form
More fin radiators force distinguished and admirable by fin clearance process resistance very little because fin is planar structure, and forced stream cannot be with
Fin surface comes into full contact with, and causes radiating efficiency not high.
Invention content
The invention mainly solves the technical problem of providing a kind of heat spreader structures, overcome prior art radiating efficiency not high
The shortcomings that, after the fin by wave rectangular groove structure, the cross-ventilation that can be formed causes air more to come into full contact with, and realizes
Efficiently quickly heat exchange, improves heat transfer and radiating efficiency.
In order to solve the above technical problems, one aspect of the present invention is：A kind of heat spreader structures are provided, are wrapped
Upper spacer, lower clapboard, fin, left strip of paper used for sealing and right strip of paper used for sealing are included, the fin is arranged between upper spacer and lower clapboard, described
Left strip of paper used for sealing and right strip of paper used for sealing be respectively connected between upper spacer and lower clapboard left and right ends, the fin use wave square
Shape slot structure.
In a preferred embodiment of the present invention, the upper spacer and lower clapboard are all made of aluminum plate.
In a preferred embodiment of the present invention, the thickness of the upper spacer and lower clapboard is equal or unequal.
In a preferred embodiment of the present invention, the material of the fin is metal material, is integrally formed using punching press.
In a preferred embodiment of the present invention, the material of the fin is stainless steel material.
In a preferred embodiment of the present invention, the stainless steel using austenitic stainless steel 304,306,316 or
316L is one such.
The beneficial effects of the invention are as follows：The heat spreader structures of the present invention, the disadvantage for overcoming prior art radiating efficiency not high,
After fin by wave rectangular groove structure, the cross-ventilation that can be formed causes air more to come into full contact with, and realizes efficiently fast
Quick change heat, improves heat transfer and radiating efficiency.
Description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, wherein：
Fig. 1 is the structural schematic diagram of a preferred embodiment of heat spreader structures of the present invention；
Label in attached drawing be：1, upper spacer, 2, lower clapboard, 3, fin, 4, left strip of paper used for sealing, 5 right strip of paper used for sealings.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
As shown in Figure 1, the embodiment of the present invention includes：
A kind of heat spreader structures, including upper spacer 1, lower clapboard 2, fin 3, left strip of paper used for sealing 4 and right strip of paper used for sealing 5, the fin 3 are set
It sets between upper spacer 1 and lower clapboard 2, the left strip of paper used for sealing 4 and right strip of paper used for sealing 5 are respectively connected to upper spacer 1 and lower clapboard 2
Between left and right ends, the fin 3 uses wave rectangular groove structure, the cross-ventilation that can be formed to cause air more abundant
Contact.
Among the above, the upper spacer 1 and lower clapboard 2 are all made of aluminum plate.Wherein, the upper spacer 1 and lower clapboard 2
Thickness be it is equal or unequal.
Further, the material of the fin 3 is metal material, is integrally formed using punching press.It is described in the present embodiment
Fin 3 material be stainless steel material.Wherein, the stainless steel uses 304,306,316 or 316L of austenitic stainless steel
It is one such, good heat dissipation effect.
In conclusion the heat spreader structures of the present invention, the disadvantage for overcoming prior art radiating efficiency not high pass through wave square
After the fin of shape slot structure, the cross-ventilation that can be formed causes air more to come into full contact with, and realizes efficiently quickly heat exchange, carries
High heat transfer and radiating efficiency.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
