Description
Technical field
The utility model, about a kind of heat spreader structures, refers in particular to a kind of heat spreader structures with dust reduction capability.
Background technology
Along with electronic product make rapid progress development, its volume is more and more less, performance and power increasing, air-cooled radiator, because its heat dispersion is far above air cooling heat radiator, is more and more subject to the welcome in market.
But in radiator, modal problem is the laying dust problem of radiator at present, radiator laying dust is mainly because when air is by radiator, dust granules in air is due to the stop of radiator fin, dust granules in air clashes on a heat sink, the air outlet place that partial particulate can stick to radiator fin forms dust, gap between fin is less, the situation of its dust accumulation is more serious, under accumulating over a long period, air inlet passage can be caused to reduce, hinder the flowing of wind, the heat dispersion of radiator is caused to decline, jeopardize the useful life of electronic component, serious also can quit work by the too high product that causes of Yin Wendu.
The most simple effective method of head it off increases the gap between fin, reduces the collision between wind and fin.But between fin, the increase in gap can make again fin quantity and area of dissipation reduce, and causes heat dispersion to decline.So how effectively to reduce dust is this area problem demanding prompt solution in the accumulation of radiator.
Utility model content
Because the problems referred to above, the purpose of this utility model is under the prerequisite not reducing radiating effect, reduces the accumulation of dust in radiator.
For achieving the above object, the utility model provides a kind of heat spreader structures, comprise a base, described base is provided with spaced first fin and the second fin along first direction, and described first fin and described second fin are that front-back staggered arranges along the second direction perpendicular to described first direction.
Heat spreader structures of the present utility model, arranged by the front-back staggered of the first fin and the second fin, make air when by radiator, the space passed through adds one times, decrease the shock between air and fin, significantly reduce dust adhesion possibility on a heat sink, reach good dust-proof effect.
The further improvement of the utility model heat spreader structures is, the structure of described first fin and described second fin is rectangular configuration.
The further improvement of the utility model heat spreader structures is, the structure of described first fin and described second fin is parallelogram sturcutre.Because the first fin and the second fin are parallelogram sturcutres, area of dissipation does not reduce, therefore its radiating effect can't reduce, and collides because this parallelogram sturcutre reduces and reduce windage loss, makes the life-span of radiator promote to some extent to a certain extent.
The further improvement of the utility model heat spreader structures is, the end of described first fin is obliquely installed along described second direction, and the end of described second fin is obliquely installed along the third direction contrary with described second direction; Or the end of described second fin is obliquely installed along described second direction, the end of described first fin is obliquely installed along the third direction contrary with described second direction.
The further improvement of the utility model heat spreader structures is, the structure of described first fin and described second fin is trapezium structure.Because the first fin and the second fin are trapezium structures, area of dissipation does not reduce equally, therefore its radiating effect also can't reduce, and collides because this trapezium structure reduces and reduce windage loss, also makes the life-span of radiator promote to some extent to a certain extent.
The further improvement of the utility model heat spreader structures is, the structure of described first fin is the trapezium structure that upper base is less than bottom, and the structure of described second fin is the trapezium structure that upper base is greater than bottom; Or the structure of described first fin is the trapezium structure that upper base is greater than bottom, the structure of described second fin is the trapezium structure that upper base is less than bottom.
