Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a radiator comprising a plurality of dissipation pieces provided with bending edges, which are connected in series through the insert of bolt.

2. Description of the Prior Art

The radiator (shown as FIG. 1) is the essential apparatus in electronic equipment, which collocates with fan (not show) to discharge the heat air in closed electronic devices space so as to avoid the high temperature induced equipment fault. Generally, the combination of the radiator 1 uses the lamination formed from the metals with good heat conductivity, such as Cu, Al, etc. to absorb heat energy, and discharges the heat air through the fan or heat interchange between air. On a common radiator 1, the dissipation pieces 10 for heat dissipation are usually laterally arranged pieces combination (shown as FIG. 1, FIG. 2), and during manufacturing process, generally, these dissipation pieces 10 should be provided with joint hole 11 which will then be bent at two sides, finally, be combined through the joint hole 11, thus it is complicated in procedure, furthermore, the thickness of each lamination is extremely thin and is extremely fine during manufacturing, thus the manufacturing cost increases naturally and the yield is not high. Conventional radiator 10 structure induced another disadvantage that due to the formation of the joint hole 11, it is necessary to move a gap of a trough 12 to be served as the joint space left for jointing with the protruding joint 13, which results that the least thickness of the bending edge 14 of the radiator 10 must be greater that the thickness of the trough 12, thus, even the radiator 10 can be combined with connected dissipation pieces, the distance between pieces is still confined to be greater than or equal to the thickness of the bending edge 14. Above-mentioned radiator 10 structure influences greatly on the manufacture of the radiator 10 due to the sizes of the devices in the electronic equipment are often confined, even the radiator itself is not an exception, and the dissipation effect of the radiator depends on the number of the dissipation pieces, if above-mentioned dissipation pieces 10 structure must be formed to be with the distance of the dissipation pieces comparable with the bending edge 14, in principle, it is hard to achieve the enhancement of dissipation efficiency through increasing the number of dissipation pieces in limited space.

SUMMARY OF THE INVENTION

The present invention provides a radiator structure capable of increasing more dissipation pieces than conventional radiator, and the dissipation efficiency of the radiator can be enhanced via integral combination of more dissipation pieces. Whereas, the radiator of the present invention includes a plurality of dissipation pieces combined mutually in series via the devices of insert or bolt, etc., wherein two opposite edge of the dissipation pieces bend inwardly to form bending edges, wherein one bending edge is formed on two ends of the said edge and the middle section between is with non-bending edge. Due to there is no joint structure employed on above-mentioned bending edge, the bent thickness of the bending edge can be minimum, thus the distance between various dissipation pieces after combining in series can be shrunk to the full, consequently, more dissipation pieces can be involved in limited space of the radiator, and the dissipation efficiency of the radiator can be enhanced via the increase in the number of the dissipation pieces. The joints between the dissipation pieces of the present invention utilize the device capable of connecting all dissipation pieces in series, the said device may be one kind of insert, bolt or shaft, etc., of course, to achieve the joint object, the surface of the dissipation pieces may be provided with the means such as aperture or groove, etc., and if the surface of the device for combining the dissipation pieces in series is smooth, it may be provided with trench on the said surface to be convenient for enhancing the fixed combination of the dissipation pieces and the said device. Further, the two opposite bending edge of the dissipation pieces may be with any shape capable of forming minimum distance between dissipation pieces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The preferred embodiment of the present invention includes a plurality of dissipation pieces connected mutually in series via the devices such as insert or bolt, wherein [0012] dissipation pieces 2 is a piece body (shown as FIG. 4), the upper and lower edges thereof form the bending edge 21, 22, respectively, wherein the upper bending edge 21 is formed at two ends thereof, and the lower bending edge 22 is continuous, of course, above-mentioned bending edges can be provided on the left and right edges of the said dissipation pieces 2. The form of the dissipation pieces can be various such as the bending edges 23, 24 shown in FIG. 5, FIG. 6, or other form capable of forming minimum width after bending. There is hole provided between the two opposite bending edges 21, 22 of above-mentioned dissipation pieces 2 for locating the devices such inset or bolt, etc., which may be groove 25 shown as FIG. 4 or aperture shown as FIG. 5, certainly, if it is needed, the number of the hole provided on the dissipation pieces 2 may be increased, and the form thereof may be any appropriate one (shown as FIG. 6).
Please referring to FIGS. 7, 8, the present invention utilizes the devices such as insert [0013] 31 of bolt 32, etc. to pass through every dissipation pieces 2, and the end thereof is mounted by the way of bending or riveting or screwing to make dissipation pieces 2 be connected closely. The dissipation pieces 2 shown in FIG. 7 adopt lateral combination, while in FIG. 8, it is vertical connected in series. The radiator of above combination blows in the cold air form the side of the dissipation pieces 2 via the means of fan, etc. (not shown), and discharges the heat absorbed by the dissipation pieces 2 through the non-bending edge section 27 between the two upper bending edge 21 (shown as the arrow in FIG. 4), thus the said non-bending edge section 27 is the exhaust open of the said radiator 4. If the combination of the dissipation pieces 2 of the present invention adopts the way of insert 31, the surface of the insert 31 may be provided with scar of ditch 311 (shown as FIG. 7), the major object of the said ditch 311 is to combine the dissipation pieces 2 fixedly, the principle thereof is shown as FIG. 9, due to the groove 25 provided on the dissipation piece 2, which forms a bending piece 28 bent outward, while the insert 31 combines the dissipation pieces 2 right in the arrow direction, the said bending piece 28 can bounce on the surface of the insert 31 and will not confine the insert 31, and after combining the insert 31 and the dissipation pieces 2, the end 281 of the bending piece 28 will wedge into the pitch 311 of the insert 31 exactly, and the wedging phenomenon can avoid the dissipation pieces 2 from moving right in arrow direction, i.e. cannot depart from the insert 31, thereby the dissipation pieces 2 can be connected closely and fixedly via the insert 31. It will be appreciated that, it is not necessary to provide ditch 311 on the surface of the insert 31, due to the bending piece 28 of the dissipation pieces 2 can only be bent out in right direction, if it is desired to make the dissipation pieces 2 move toward right direction, i.e. depart from the insert 311, it will be wedged more by the bending piece 28 and be hard to achieve.
