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 mm² (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 mm² (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 mm². That is to say, the superficial area of the protruding fin 42 has preferably at least one time of the conventional protruding fins (1200 mm²) 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.
