Title: Tubular radiating seat integrally formed by one working procedure

Description:
BACKGROUND OF THE INVENTION 
     (a) Field of the Invention 
     The present invention relates to a design of a tubular radiating seat integrally formed by one working procedure, which structures a hollow radiating seat by punching or extruding (hydraulic) an aluminum solid disk of a fixed amount, thereby allowing a closed end as well as several slots on a wall to be integrally and concurrently constructed on the tubular radiating seat. 
     (b) Description of the Prior Art 
     A conventional radiator surrounded by several heat-dispersing fins mainly comprises a number of heat-dispersing fins and a tubular radiating seat. The manufacturing cost of this radiator is in fact expensive since the fins have to be integrally arranged on an outer wall of the tubular radiating seat. Moreover, such radiator is also bulky and heavy; further worse, the amount of the fins is limited. As a result, the effect of heat dispersion of the radiator is somehow unsatisfactory. 
     The conventional tubular radiating seat of the radiator attaches a closed end to a heating unit, for instance, the CPU or the LED units, thereby scattering the heat. Alternatively, a heating tube that collects heat could be freely adopted so as to enhance the efficiency of heat dispersion. The formation of the tubular radiating seat could be circular, square, or polygonal, etc. 
     There is another kind of conventional tubular radiating seat that utilizes a radiating tray having a central hole to combine with a hollow tubular seat. Herein, the radiating tray and the hollow tubular seat are two individual components. Therefore, where the two components are combined easily results in capillarity and incurs thermal resistance. Herein, the unsatisfactory absorbing and the substandard transmission of the heating temperature invite an adverse heat dispersion effect. In addition, the costs for respectively molding the radiating tray and the hollow tubular seat are high, and the two components have to be further assembled by an extra working procedure. Thus, such laborious and time-consuming means for producing the high-cost radiator is rather uneconomical. 
     SUMMARY OF THE INVENTION 
     It is therefore the purpose of this invention to provide a tubular radiating seat integrally formed by one working procedure. The present invention comprises a hollow radiating seat that is structured by punching or extruding (hydraulic) a fixed amount of an aluminum solid disk. A front part or a middle part of the tubular radiating seat has an integral closed end, and a plurality of slots are integrally formed on an outer wall of the tubular radiating seat for combining with a correspondent fin set. Accordingly, the tubular radiating seat is compactly and integrally formed, which simplifies the manufacturing procedure and reduces the producing costs. Fewer problems would be caused in view of joints, and the capillarity is not a question anymore. The effect of heat dispersion is greatly enhanced since the thermal resistance is prevented and the heating temperature is well absorbed. 
     A further purpose of this invention is to provide a tubular radiating seat integrally formed by one working procedure structures the closed end on the front part of the tubular radiating seat with a protrudent periphery that is integrally built. Preferably, a sunken part is integrally structured in the protrudent periphery. Preferably, a groove is formed on an inner wall of the sunken part by a turning procedure. In order to attach the closed end, the protrudent periphery, or the sunken part to a heating unit, the slots could cooperate with a light cover.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to  FIGS. 1 to 4 , a first preferred embodiment of the present invention is shown. A tubular radiating seat integrally formed by one working procedure comprises a hollow radiating seat  1  that is structured by punching or extruding (hydraulic) a fixed amount of an aluminum solid disk. A front part or a middle part of the tubular radiating seat  1  has an integral closed end  11  (as shown in  FIG. 3  and  FIG. 4 ). A plurality of slots  12  are integrally formed on an outer wall of the tubular radiating seat for combining with a correspondent fin set  2 . Succeedingly, the fin set  2  is compactly combined and inserted within the outer wall of the tubular radiating seat  1 , so that the tubular radiating seat  1  is provided with the fin set  2 . 
     The appearance of the just punched or extruded (hydraulic) tubular radiating seat  1  may be coarse. Wherein, the coarse appearance could be easily smoothened by a processing device. 
     Apparently, the manufacturing of the tubular radiating seat is trouble-free and the subsequent processing is also uncomplicated. Therefore, the tubular radiating seat  1  could be helpfully cost-down in the production, so it is also competitive and practical in the market. 
     As mentioned in afore embodiment, the closed end formed on the front part  11  of the tubular radiating seat  1  has a protrudent periphery  111  that is integrally structured. Or further, a sunken part  112  could be integrally structured in the protrudent periphery  111 . Accordingly, attaching the closed end  11 , the protrudent periphery  111 , or the sunken part  112  to a heating unit, such as a CPU or LED units preferably enhances the heat absorbing and dispersing effect. 
     Continuingly, a groove  113  could be alternatively formed on an inner wall of the sunken part  112  by a turning procedure for suiting with a light cover  3  (as shown in  FIG. 5 ). When an electric connector  4  is further cooperated, a projecting light (as shown in  FIG. 6 ) is provided. Wherein, at least one set of LED units could be previously inserted on the closed end  11 , the protrudent periphery  111 , or the sunken part  112  of the tubular radiating seat  1 . 
     Referring to  FIGS. 7 to 10 , a second preferred embodiment of the present invention is shown. In this embodiment, a protrudent periphery  111   a  is integrally formed around the closed end  11   a  at the front part of the tubular radiating seat  1   a.  Moreover, a plurality of slots  12   a  are integrally formed on an outer wall of the tubular radiating seat  1 , so that the tubular radiating seat could be surroundingly combined with a fin set  2   a.  Namely, the sunken part  112  existing in the first preferred embodiment could be herein omitted. Moreover, one end of the fin set  2   a  could be designed in accordance with the formation of the protrudent periphery  111   a  so as to inherently conduce to a depression  21   a.  Accordingly, the fin set  2   a  could enclose the protrudent periphery  111   a.    
       FIGS. 11 to 13  show a third preferred embodiment of the present invention. Wherein, a closed end  11   b  (as shown in  FIG. 13 ) is integrally structured on the middle part of the tubular radiating seat  1   b.  A plurality of slots  12   b  are integrally formed on the outer wall of the tubular radiating seat  1   b  for correspondingly cooperating with an annular fin set  2   b.  Whereby, the fin set  2   b  could be compactly and perfectly combined with the outer wall of the tubular radiating seat  1   b,  thereby achieving a tubular radiating seat  1   b  provided with the fin set  2   b.    
     To sum up, the present invention particularly utilizes the tubular radiating seat  1 / 1   b  that is integrally formed by one working procedure to let the solid closed end  11 / 11   a / 11   b  attach to the heating unit. Moreover, the slots  12 / 12   a / 12   b  are also provided for compactly cooperating with the fin set  2 / 2   a / 2   b.  Obviously, joint is not a problem for the tubular radiating seat  1 , and the opportunity of capillarity is also reduced. In addition, extra thermal resistance is prevented, which promotes the heat absorbing effect and enhances the heat dispersion efficiency. As a result, the manufacturing of the present invention is simplified, and the correlated costs are preferably reduced.
