TUBULAR RADIATING SEAT INTEGRALLY FORMED BY ONE WORKING PROCEDURE - Patent application
Patent application title: TUBULAR RADIATING SEAT INTEGRALLY FORMED BY ONE WORKING PROCEDURE
IPC8 Class: AF28F124FI
Patent application number: 20130233527
[0002] 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.
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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.
[0008] 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.

[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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.
[0027] Referring to FIGS. 7 to 10, a second preferred embodiment of the present invention is shown. In this embodiment, a protrudent periphery 111a is integrally formed around the closed end 11a at the front part of the tubular radiating seat 1a. Moreover, a plurality of slots 12a 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 2a. Namely, the sunken part 112 existing in the first preferred embodiment could be herein omitted. Moreover, one end of the fin set 2a could be designed in accordance with the formation of the protrudent periphery 111a so as to inherently conduce to a depression 21a. Accordingly, the fin set 2a could enclose the protrudent periphery 111a.
[0028] FIGS. 11 to 13 show a third preferred embodiment of the present invention. Wherein, a closed end 11b (as shown in FIG. 13) is integrally structured on the middle part of the tubular radiating seat 1b. A plurality of slots 12b are integrally formed on the outer wall of the tubular radiating seat 1b for correspondingly cooperating with an annular fin set 2b. Whereby, the fin set 2b could be compactly and perfectly combined with the outer wall of the tubular radiating seat 1b, thereby achieving a tubular radiating seat 1b provided with the fin set 2b.
[0029] To sum up, the present invention particularly utilizes the tubular radiating seat 1/1b that is integrally formed by one working procedure to let the solid closed end 11/11a/11b attach to the heating unit. Moreover, the slots 12/12a/12b are also provided for compactly cooperating with the fin set 2/2a/2b. 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.
