Abstract

The utility model relates to a heat dispelling sheet structure for the compound heat radiator. The utility model is mainly characterized in that the joint part of the heat dispelling sheet forms two clip connected sheets with a button sew between each other; the bottom side part which the joint part of the two clip connection sheets extends to is concave provided with a blocking button sheet; the button ear of the blocking button sheet is in the corresponding position of the button sew and the blocking button sheet is a little larger that the clearance of the button sew; when the two clip connected sheets are folding positioned on the heat dispelling sheet, the blocking button sheet on the baseboard of the upper heat dispelling sheet can insert into the button sew between the lower heat dispelling sheet and the clip connected sheet. The blocking button sheet is little larger than the button sew and is fixed though the springy strain of the two clip connected sheets and the blocking button sheet is not easy to loose and the upper and lower heat dispelling sheets can be combined closely. The utility model adopts the plural number of heat dispelling sheets which can button and fix and do not loose, and the two blocking button sheets of the upper and lower heat dispelling sheets forms certain space to make the heat dispelling sheet of the whole radiator has a good heat dispelling clearance and to from a steady and continuous radiator structure with an extending heat dispelling area.

Description

The heat radiating fin structure of combined radiator

Technical field

The heat radiating fin structure of the utility model combined radiator, mainly providing one can be by the mutual stacked location of each fin, and form the combined radiator structure that tight button is held effect mutually by each fin, and formed certain between mutually stacked fin apart from spacing, to form a good heat radiation gap, and then form the heat spreader structures of a firm and sustainable extension area of dissipation, more being different from known combination formula radiator need be interspersed between each fin by the plant plate, cooperate buckle to press again in the structural form of the fin top of the superiors, has the reduction manufacturing cost, promote production capacity, and the advantage that increases the assembling convenience.

Background technology

Press, general known radiator be mostly by aluminium alloy with extrude or the mode of die casting one-body molded, and make the integral heat sink utensil that a plurality of fin that are appropriate intervals configuration be arranged, forms the area that dispels the heat with panel, so as to reaching the effect of heat radiation by each fin; Yet integrated radiator is owing to have specific profile specification, and reduces its scope of application, and the fine degree of the fin of its integral heat sink device (quantity) is limited, relatively directly influences the radiating effect of radiator.So, have modular radiator in the market, its integral heat sink device is to be shaped with the mutually stacked assembling of the fin of metal sheet formed thereby, mainly the stacked effect by each sheet metal increase fin quantity and and then increase the area of dissipation of radiator; But,, and make and heat-dissipating space deficiency between each fin can't reach radiating effect on the contrary as expection because almost be that to become the state that reclines mutually stacked between the fin of its modular radiator.

Yet, combined radiator in the market has in order to the stacked mutually fin except need, more essential by the assembling of a matrix for fin, it is to be provided with upright plant plate on matrix, and on fin, be provided with for what the plant plate interted and wear groove, have by the plant plate fin is formed positioning action, press above the fin of the superiors by a buckle more at last, and by buckle and the interspersed fastening effect of plant plate, the combination of integral heat sink sheet reached press fixing effect, so will too much make the assembling action be tending towards complicated because of the number of components, and need finish the making of each member with different moulds, and the cost of manufacture of integral heat sink device is increased; Especially, the height of integral heat sink device also is subject to the set limitation in height of plant plate and does not more have variability.

Technology contents

The main purpose of the heat radiating fin structure of the utility model combined radiator provides one can be by the mutual stacked location of each fin, and form tight button mutually by each fin and hold effect, and formed certain between mutually stacked fin apart from spacing, forming a good heat radiation gap, and then form the heat spreader structures of a firm and sustainable extension area of dissipation.

Another purpose of the heat radiating fin structure of the utility model combined radiator is directly by the mode of punch process, to the in addition moulding of the structure of fin sticking part and buckling piece, makes the entire heat dissipation sheet be able to one machine-shaping.

The technical solution of the utility model is: a kind of heat radiating fin structure of combined radiator, its integral heat sink device are that the fin phase stacked combination by the metal sheet formed thereby forms, and this fin has base plate, is provided with side plate at base plate two corresponding avris, wherein:

Extend upward more than one at least sticking part in the appropriate position of side plate, this sticking part is slightly to be extended upward by side plate and form two corresponding snapping sheets, two snapping sheets provide has first applying limit of upholding elastic force and the second applying limit that slightly has angle with the first applying limit, to form the button seam by the first applying limit and the second applying limit, and form window between two second applying limits, be provided with buckling piece and correspond to avris place, bottom surface in the button seam, these buckling piece two sides are formed with groove, and distance is slightly larger than the spacing on two first applying limits of button seam about buckling piece, and buckling piece about distance be slightly less than the spacing of window.

Like this, at fin up and down during stacked combination, towards the fin reflexed side plate and sticking part are erect the side plate of fin, the buckling piece of top fin buckles in the seam by the window of below fin, by a fixture slightly broken to the button seam in the second applying limit again and roll over, utilize the second applying limit of snapping sheet that buckling piece is fixed, and buckling piece is snapped in the button seam by the first applying limit extension elastic force of two snapping sheets.

The utility model passes through said structure, make its buckling piece be difficult for getting loose, and fin is combined closely up and down, borrow a plurality of fin can fasten the location mutually and do not get loose, and it forms up and down certain for spacing between two buckling pieces of fin, to form a good heat radiation gap, and then form the heat spreader structures of a firm and sustainable extension area, more being different from known combination formula radiator need be interspersed between each fin by the plant plate, cooperates buckle to press the combined radiator structure of the structural form above the fin of the superiors again.
