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. 
     2. Description of the Prior Art 
     The prior art radiator (shown as FIG. 1) is part of the electronic equipment, in conjunction with a fan (not shown) configured to discharge heated air in closed spaces of electronic devices to avoid high temperature induced equipment failure. Generally, the radiator utilizes laminated structures formed from the metals with good heat conductivity, such as copper, aluminum, etc. to absorb heat energy, and discharges the heated air through the fan or heat interchange with air. On a common radiator  1 , the dissipation pieces  10  for heat dissipation are usually a combination of laterally arranged pieces (shown as FIG. 1, FIG.  2 ). During the manufacturing process, these dissipation pieces  10  should be provided with joint holes  11  that are bent at two sides and combined through the joint holes  11 , the procedure of which is complicated. In addition, the thickness of each lamination is extremely thin and is extremely delicate during manufacture, thus the manufacturing cost is increased and the yield is not high. The conventional radiator  10  includes another disadvantage in that due to the formation of the joint holes  11 , it is necessary to form a gap of a trough  12  to serve as the joint space for jointing with the protrusion joint  13 , which results in that the smallest thickness for the bending edge  14  of the radiator  10  must be greater than the thickness of the trough  12 , such that even the radiator  10  can be combined with connected dissipation pieces, but the distance between pieces is still configured to be greater than or equal to the thickness of the bending edge  14 . The shape of the radiator  10  structure greatly influences the manufacture of the radiator  10  due to the sizes of the devices in the electronic equipment that are often confined, and the radiator itself is not an exception, and the dissipation effect of the radiator depends on the number of the dissipation pieces. If the dissipation pieces  10  must be formed with the distance of the dissipation pieces being comparable with the bending edge  14 , in principle, it is hard to achieve the enhancement of dissipation efficiency by increasing the number of dissipation pieces in a limited space. 
     SUMMARY OF THE INVENTION 
     The present invention provides a radiator structure capable of adding more dissipation pieces than a conventional radiator, and the dissipation efficiency of the radiator can be enhanced via integral combination of more dissipation pieces. The radiator of the present invention includes a plurality of dissipation pieces combined mutually in series via a connection device such as an insert or bolt, etc., wherein two opposite edges of the dissipation pieces are bent inwardly to form bending edges, wherein a bending edge is formed on two ends of the edge and the middle section therebetween is an unbent edge. Since there are no joint structures employed on the bending edge, the bent thickness of the bending edge can be minimized, thus the distance between various dissipation pieces after being combined in series can be reduced. Consequently, more dissipation pieces can be packed in the limited space of the radiator, and the dissipation efficiency of the radiator can be improved via the increase in the number of the dissipation pieces. The joints between the dissipation pieces of the present invention utilize a connection device capable of connecting all of the dissipation pieces in series. The connection device may be one kind of insert, bolt or shaft, etc., and to achieve the connection, the surface of the dissipation pieces may be provided with means such as apertures or grooves, etc., and if the surface of the device for combining the dissipation pieces in series is smooth, it may be provided with a trench on the surface for enhancing the fixed combination of the dissipation pieces and the connection device. Further, the two opposite bending edge of the dissipation pieces may be of any shape capable of forming a minimum distance between the 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 a connection device such as an insert or bolt, wherein the dissipation pieces  2  each includes a piece body (shown as FIG.  4 ), the upper and lower edges thereof form opposing inwardly bending edges  21 ,  22 , respectively, wherein the upper bending edge  21  is formed at two ends thereof, and the lower bending edge  22  is continuous. The bending edges  21 ,  22  can be provided on left and right edges of the dissipation piece  2 . The form of the dissipation pieces can be varied, as shown in various shapes of the bending edges  23 ,  24 , as shown in FIGS. 5 and 6, or other forms that are capable of forming a minimum width after bending. A hole is provided between the two opposite bending edges  21 ,  22  of each of the mentioned dissipation pieces  2  for insertion thereof an insert or bolt, etc., which may be an opening or groove  25 , as shown in FIG. 4 or aperture  26 , as shown in FIG.  5 . If necessary, the number of holes provided on each of the dissipation pieces  2  may be increased, and the form or shape thereof may be reconfigured as shown in FIG.  6 . 
     Referring to FIGS. 7 and 8, the present invention utilizes an insert  31  or bolt  32 , etc. to connect adjacent dissipation pieces  2 , and the ends thereof are mounted by bending or riveting or screwing to arrange the dissipation pieces  2  to be connected closely. The dissipation pieces  2  shown in FIG. 7 are laterally combined, while in the embodiment of FIG. 8, the dissipation pieces are vertically connected in series. Cold air from the side of the dissipation pieces  2  blows into the radiator via the means of a fan, etc. (not shown), and discharges the heat absorbed by the dissipation pieces  2  through the non-bending edge sections  27  between the two upper bending edges  21  (arrows in FIG. 4 show air flow directions). Thus, the flat edge section  27  of the dissipation piece  2  is the exhaust outlet of the radiator  4 . If the combination of the dissipation pieces  2  of the present invention are connected by way of the inset  31 , the surface of the insert  31  may be provided with ditches  311  (as shown in FIGS.  7  and  9 ). A major object of the ditch  311  is to fixedly combine the dissipation pieces  2  in the manner shown in FIG. 9, wherein the opening or groove  25  is provided on the dissipation piece  2 , which is formed by outwardly bending a bending piece  28 , while the insert  31  combines with the dissipation pieces  2  right in the direction of the arrow of FIG. 9, and the 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 ends  281  of the bending pieces  28  will precisely wedge into respective pitches  311  of the insert  31 , and this wedging prevents the dissipation pieces  2  from moving further in the direction of the arrow of FIG. 9 such that they cannot depart from the insert  31 . Thus, 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 , duet to the bending piece  28  of the dissipation pieces  2  that can only be bent out in a right direction, as shown in FIG. 9, if it is desired to make the dissipation pieces  2  move toward the right direction, i.e. depart from the insert  311 , since the dissipation pieces  2  will be wedged more by the bending piece  28 .
