1. Field of the Invention
The present invention relates to a cooling fin structure for mechanical equipments, which can solve the high temperature problem caused during the running process by cooperating with liquid to absorb the heat quickly to reduce the temperature.
2. Description of the Prior Art
Most of equipments, such as cars or motobicycles, are likely to generate heat during running process, which will cause high temperature and damage the inner components of the equipments, thus leading to the unsmooth operation. In order to ensure smooth operation of the equipments, a cooling fin structure capable of dissipating heat quickly was developed on the market. As shown in
By such arrangements, after the respective cooling fins 60 are parallely spacedly assembled, the liquid pipes 70 will penetrate the respective through holes 61 and then fixed therein by means of adhesive, heat sink paste or welding. Next, the liquid base assembly 80 will be combined to both ends of the respective liquid pipes 70 in such a manner that gas or liquid can flow in and out of the respective liquid pipes 70 through the inlet 81 and the outlet 82, respectively. When the gas or the liquid flows through the respective cooling fins 60, the heat in the gas or the liquid can be absorbed by the respective cooling fins 60 and then dissipated into the air to cool down the gas or the liquid that flows through the respective liquid pipes 70.
The above conventional structure suffers from the following disadvantages: since the cooling fins 60 are independent from the liquid pipes 70, there must be a clearance between the respective cooling fins 60 and the respective liquid pipes 70, thus causing poor heat conductivity, in addition, in order to improve the poor heat conductivity caused by the clearance, after penetrating the through holes 61 of the cooling fins 60, the respective liquid pipes 70 must be bonded to the respective cooling fins 60 by means of adhesive, heat sink paste or welding, so that it can be found that the conventional structure is complicated in assembly and has various components, furthermore, even through the cooling fins 60 are bonded to the liquid pipes 70 by means of adhesive, heat sink paste or welding, they are still independent from each other and unable to exert the optimal cooling effect.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The technical problems to be solved:
As for the conventional cooling fin structure, since the heat sinks and the liquid pipes are independent form each other, the heat conductivity is poor, and since the heat sinks are bonded to the respective liquid pipes by means of adhesive, heat sink paste or welding, the conventional cooling fin further has the disadvantages of complicated in assembly and various components.
In order to solve the above technical problems, a cooling fin in accordance with the present invention is integrally formed and comprises a board body, a passage penetrating the board body and plural heat dissipating portions located outside the board body in the direction along the passage. Between each two neighboring heat dissipating portions is defined a heat dissipating space.
As compared to the conventional cooling fin structure, the cooling fin of the present invention has the following advantages:
The primary objective of the present invention is to provide a cooling fin, since the cooling fin is integrally formed and all the structures are integrally connected, so that the cooling fin in accordance with the present invention has the advantages such as better heat dissipation effect, without any assembling operations and procedures, easy to assemble and simple structure.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiments in accordance with the present invention.
Referring to
As shown in
With the above operation method of the cooling fin 10, when the liquid flows through the passage 12 of the cooling fin 10, the heat in the liquid will be directly conducted to the board body 11 and the heat dissipating portions 14, so that the heat will be dissipated into the air by the heat dissipating portions 14 to cool down the liquid that flows through the cooling fin 10.
With the above structures in the preferred embodiment, the present invention has the following advantages: since the entire cooling fin 10 is integrally formed, and all the structures are integrally connected, the cooling fin 10 of the present invention has the advantages of better heat dissipation effect and further without welding or adhesive bonding means; and since a single cooling fin 10 comprises a board body 11, a passage 12, plural heat dissipating portions 14 and plural heat dissipating spaces 15, there is no need for any assembling operations and procedures, thus having the advantages of easy to assemble and simple structure. The cooling fin 10 has various applications such as the cooling fin 10 can be used singly or plural cooling fins 10 are used in a cooperation manner. Further, when being used in the cooperation manner, the plural cooling fins 10 can be assembled to one another in a lapping manner as desired.
While we have shown and described various embodiments 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.
