Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a radiator, in particular to a radiator that renders preferable heat dissipation by an increment of the superficial area of the protruding fins for expansively contacting with the outer air. 
         [0003]    2. Description of the Related Art 
         [0004]    A conventional radiator  1  as shown in  FIG. 1  comprises a base body  12  and a plurality of protruding fins  11  outward extended from the base body  12 . Wherein, the conventional protruding fins  11  may have various arrangements or shapes for being adapted to different radiators. Herein the protruding fins  11  are arranged in a vertical state and provided with level surfaces. Supposed that a dimension of each protruding fin  11  is measured by 40 millimeter (mm) in length, 4 mm in width, and 10 mm in height, the total surface area of each protruding fin  11  would hence be 1200 mm 2  (square millimeter). In addition to making use of the protruding fins  11  on different arrangements to promote heat-dissipating efficiency, it is also a trend to manufacture the radiator  1  by materials possessing the property of better heat radiation, such as gold, silver, copper, aluminum, magnesium, tin, silicon, other applicable metals, etc. 
         [0005]    There is a wide application of the conventional radiator  1 , for instance to apply on an engine, a condenser, or a central processing unit  3  (CPU) as now described in the following application and shown in  FIG. 2 . It essentially provides with the base body  12  contacting a surface of the CPU  3  to render each of the protruding fins  11  extending outward therefrom. A radiator-fan  2  is further installed above the protruding fins  11 . Whereby, a thermal energy generated from the CPU  3  can be swiftly dispersed by means of the contact of the protruding fins  11  and the outer air as well as the motivation of the compelling airflow created by the radiator-fan  2 . 
         [0006]    However, the conventional radiator  1  still has the restriction on the heat-dissipating efficiency even though it may make use of various materials or appearances to improve the dispersion. That is, the inventor finds that the thermal, as arrowed in  FIG. 2 , would be restrainedly scattered between any two limited surface areas of the protruding fins  11  for contacting with the outside, which nevertheless restricts the flowing path and influences the dissipating capability. Such poor heat dissipation may even incur the shutdown of the CPU  3 . As a result, it is necessary and obvious that the radiator  1  needs improvement in dispersing heat to promote the refrigerant effect on the heating component. 
       SUMMARY OF THE INVENTION 
       [0007]    The object of the present invention is to provide a radiator to promote the heat dissipation by increasing the superficial area of the protruding fins for contacting with the outer air. 
         [0008]    The radiator in accordance with the present invention mainly provides with a base body and a plurality of protruding fins outward extended from the base body. Wherein, each protruding fin is comprised of superimposed fin pellets along with the definitions of apertures between these fin pellets so that the protruding fin is constructed by a substantively larger superficial area than that of the conventional fins. Whereby, the expandable superficial area increases the contacts of the protruding fins and the outer air and thus advances a thermal exchange between the radiator and the outer air to enhance the heat dispersing effect. Likewise, the base body can be alternatively formed by stacked pellets to accomplish a preferably heat dissipation of the radiator. 
         [0009]    The advantages of the present invention over the known prior arts will become more apparent to those of ordinary skilled in the art by reading the following descriptions with relating drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0017]    Before describing in greater detail, it should note that the like elements are denoted by the similar reference numerals throughout the disclosure. 
         [0018]    Referring to  FIG. 3 , the radiator  4  showing a first embodiment of the present invention mainly comprises a base body  41  and a plurality of protruding fins  42  outward extended from the base body  41 . Wherein, each of the protruding fins  42  is comprised of a plurality of fin pellets  422  superimposing with each other, and herein it sketchily represents in this figure by solely filling the fin pellets  422  with one protruding fin  42  and the protruding fins  42  are arranged in a vertical state. The fin pellets are preferably made from copper, aluminum, or other applicable metals that provides with a preferable conductivity. Particularly, each of the fin pellets  422  can be shaped spherical or geometric. It should be noted that the following description is described base on the fin pellets  422  being shaped spherical. In this manner, those fin pellets  422  are densely stacked to perform a superficial surface and provide with a plurality of apertures  421  defined therebetween. Base on the same condition to the conventional radiator, an axial dimension of each protruding fin  42  is accordingly presumed by 40 millimeter (mm) in length, 4 mm in width, and 10 mm in height. It can be distinctly measured that a total surface area of each protruding fin  42  is 2512.8 mm 2  (square millimeter) in view of the outer circumferences of the stacked fin pellets  422  rendering the integrally superficial surface to become uneven. 
         [0019]    The radiator  4  of the present invention is commonly applied to refrigerate calorific components, and in preferred embodiments of the present invention, the popular applications thereof to an engine, a condenser, and a central processing unit (CPU)  51  would be more plainly hereinafter set forth in the following descriptions. It is not restricted to the applications of the present radiator, as other relevant elements or components may be employed without departing from the range of the radiator  4 . 
         [0020]    For the application in a CPU  51  of a first embodiment as illustrated in  FIG. 4 , the base body  41  closely contacts a surface of the CPU  51 ; whereby, a thermal energy generated from the CPU  51  can be dispersively removed. Concurrently, a radiator-fan  52  is further installed on the top of the radiator  4 . In the light of each protruding fin  42  formed by the superimposed fin pellets  422 , their uneven appearance renders the total surface area up to 2512.8 mm 2 . That is to say, the superficial area of the protruding fin  42  has preferably at least one time of the conventional protruding fins (1200 mm 2 ) for contacting with the outer air, so that the heat dissipation of the radiator  4  accordingly increases at least twice of the conventional radiator. 
         [0021]    Furthermore, the fin pellets  422  are capable of being superimposed by one or at least one of the following assorted means, such as powder metallurgy, sintering, die-casting, welding, injection modeling, rapid prototyping manufacturing, plating, etc., whereby the fin pellets  422  are able to compose the protruding fins  42  with apertures  421  defined therebetween. Consequently, the outer air would fill between any two protruding fins  42  and freely travel through the apertures  421  toward every side of the adjacent fins  42 . Further, the thermal generated from the CPU  51  can be widely dispersed along and through the surfaces of the protruding fins  42  and drawn out therefrom as arrowed in  FIG. 4  while being subjected to the pumping pressure of the radiator-fan  52 . As a result, the radiator  4  attains a speedy heat exchange between the outer air and the protruding fins  42  and enhances a swift heat-dissipating efficiency of the CPU  51 , hence more promoting the useful application to the products, as well as further attaining a short and thin radiator with energy-saving concept. 
         [0022]    Referring to  FIG. 5  showing a second preferred embodiment of the present invention also comprises a base body  41  and a plurality of protruding fins  42  outward extended from the base body  41 . Wherein, the same formation, application, and efficiency as those of the first preferred embodiment are herein omitted. In this embodiment, the base body  41  is specifically formed by a plurality of stacked pellets  61  with apertures  62  defined therebetween. In this manner, both the protruding fins  42  and the base body  41  hence provide the expandable contacting superficial areas that conduce to more raise the heat exchange effect of the radiator  4 . 
         [0023]    Preferably, the present invention would not be restricted by the supra constructions for adapting with different calorific components. For the application in an automobile engine  8  of a third embodiment as shown in  FIG. 6 , a radiator  7  essentially comprises a frame body  71  and a plurality of protruding fins  72  outwardly extended from the frame body  71 . Wherein, the protruding fins  72  materialized by copper, aluminum, or other applicable metals possessing of a preferable conductivity are composed of a plurality of superimposed fin pellets  722  that would be utilized in the fashion consistent with the first embodiment in connection with  FIG. 4 . Whereby the fin pellets  722  making up the protruding fins  72  efficiently increases the superficial area to enhance the heat-dissipating efficiency. Concurrently, by cooperating with apertures  721  defined between the fin pellets  722 , it thence permits filling the outer air between any two protruding fins  72  as well as freely traveling through the apertures  721  toward every side of the adjacent fins  72 . Consequently, the thermal generated from the automobile engine  8  can be widely dispersed among those fins  72  as arrowed and communicated with the outer air to attain an efficient heat exchange between the outer air and the protruding fins  72 . 
         [0024]    As it should be, a radiator  9  of a fourth embodiment in  FIG. 7  showing of another appearance serves as a condenser for employing on various products or components (not shown). It essentially comprises a frame body  91  and protruding fins  92  extending therefrom composed by a plurality of superimposed fin pellets  922 . Wherein, the formation, application, and stated objectives and purposes same to the previous preferred embodiments are herein omitted. 
         [0025]    To sum up, the present invention takes advantages of each protruding fin comprised of a plurality of fin pellets superimposing with each other with apertures defined therebetween. Thus, the protruding fin has a larger superficial area to contact the outer air and allow the outer air to unrestrainedly communicate through the apertures, thereby enhancing a thermal exchange between the protruding fins and the outer air for more promoting the object of the heat-dissipating efficiency upon CPU, engine, condenser, or other components. Thence, the present radiator can desirably have broader applications to those requiring protruding fins to attain the heat dissipation. 
         [0026]    While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
