Description

本考案は、回路基板の熱釈構造に関し、特に、当該回路基板に通気や熱伝導構造の破壊という効果を与えるため、回路基板にはより良い熱釈効果が達成され、その制御ICのワーキング効率が向上されるものに関する。 The present invention relates to a heat-dissipating structure of a circuit board, and in particular, to give the circuit board an effect of venting or destroying a heat conduction structure, a better heat-dissipating effect is achieved in the circuit board, and the working efficiency of its control IC Relates to what is improved.

従来のものは、例えば、
当該ファン回路基板の第1の表面に位置し、発熱素子がある、回路素子域と、
当該第1の表面の縁に位置し、当該発熱素子と接続する放熱フィルムと、がある、中華民国特許公告公報第566828号の「ファン回路基板及びこのファン回路基板を使用するファン構造」である。
The conventional one is, for example,
A circuit element region located on the first surface of the fan circuit board and having a heating element;
The "fan circuit board and fan structure using this fan circuit board" of the Chinese Patent Publication No. 566828, which is located at the edge of the first surface and has a heat radiating film connected to the heat generating element. .

当該特許の図6、7に示すように、当該回路基板100には回路素子域102と放熱フィルム106とがあり、また、放熱フィルム106は回路基板100の縁に位置する。回路素子域102には、モータ部品を駆動するための回路と、半導体素子と、集積回路と、関係する素子とがあり、また、一部の素子は、熱を生成する発熱素子104であり、発熱素子104は、例えば、集積回路や半導体素子等である。 As shown in FIGS. 6 and 7 of the patent, the circuit board 100 has a circuit element region 102 and a heat dissipation film 106, and the heat dissipation film 106 is located at the edge of the circuit board 100. The circuit element area 102 includes a circuit for driving a motor component, a semiconductor element, an integrated circuit, and related elements, and some elements are heating elements 104 that generate heat. The heating element 104 is, for example, an integrated circuit or a semiconductor element.

放熱フィルム106は、発熱素子と接続して、発熱素子104が生成した熱を、外部へ排出するとともに、ファン構造200自体の気道設計により放熱フィルム106が排出した熱を、素早くファン構造から排出する、構造である。放熱フィルム106は、例えば、熱伝導材フィルムであり、その材質は、例えば、銅、アルミニウム、鉄及びそれらの合金等の熱伝導材である。 The heat radiating film 106 is connected to the heat generating element to discharge the heat generated by the heat generating element 104 to the outside, and quickly discharges the heat discharged from the heat radiating film 106 due to the airway design of the fan structure 200 itself from the fan structure. Is the structure. The heat dissipation film 106 is, for example, a heat conducting material film, and the material thereof is, for example, a heat conducting material such as copper, aluminum, iron, and alloys thereof.

放熱フィルム106は、回路素子域102全体を囲んでもよいし、回路素子域102除外の任意の回路基板100の部位上に位置させてもよい。また、放熱フィルム106は、図7に示すように、ハブ部202から突出して伸ばしてもよいし、ハブ部202内に位置してもよい。放熱フィルム106がハブ部202から突出して伸ばした時、放熱フィルム106がファン構造200の気道上に位置するため、放熱フィルム106を通過する空気は、素早く、放熱フィルム106が放熱した熱を受け取って離れることができる。そのため、大幅に、回路基板100の素子の電流引き受け量が向上され、ファン構造200の寿命が改善される。 The heat dissipating film 106 may surround the entire circuit element region 102 or may be positioned on any part of the circuit board 100 excluding the circuit element region 102. Further, as shown in FIG. 7, the heat dissipation film 106 may protrude from the hub portion 202 and extend, or may be located in the hub portion 202. When the heat dissipating film 106 protrudes from the hub portion 202 and extends, the heat dissipating film 106 is positioned on the airway of the fan structure 200. You can leave. Therefore, the amount of current received by the elements of the circuit board 100 is greatly improved, and the life of the fan structure 200 is improved.

また、図8に示すように、回路基板300の放熱フィルム106上にも、多数の開口108を形成することができる。好ましい開口108は、対称配列である。より良い実施例において、放熱フィルム106の開口108は、ファン構造200が稼働する時の一部の気道とされ、開口108を通過する空気により、放熱フィルム106が発散する熱は、素早く排出される。このより良い実施例においては、回路基板300の素子の電流引き受け量を大幅に向上するため、ファン構造200の寿命が改善される。 Further, as shown in FIG. 8, a large number of openings 108 can be formed on the heat dissipation film 106 of the circuit board 300. A preferred opening 108 is a symmetric arrangement. In a better embodiment, the opening 108 of the heat dissipation film 106 is a part of the airway when the fan structure 200 is operated, and the heat dissipated by the heat dissipation film 106 is quickly discharged by the air passing through the opening 108. . In this better embodiment, the lifetime of the fan structure 200 is improved because the current acceptance of the elements of the circuit board 300 is greatly increased.

上記の構造により、回路基板の素子の電流引き受け量が向上され、ファン構造の寿命が改善されるが、当該回路基板の主な発熱源は、例えば、集積回路や半導体素子等の、当該回路基板上にある発熱素子であり、当該発熱素子は、放熱フィルムから放出される熱を、回路基板の縁に設置される放熱フィルムや、回路素子域全体を囲む放熱フィルム、或いは回路素子域除外の回路基板上の任意部位にある放熱フィルムにより、ファン構造自体の気道に合せて、素早くファン構造から排出できるが、この方法は、熱伝導してから、気流を案内する方式であり、直接に当該発熱素子に対して放熱することではないため、放熱効果が制限される。 The above structure improves the current acceptance amount of the elements of the circuit board and improves the lifetime of the fan structure. The main heat source of the circuit board is, for example, the circuit board such as an integrated circuit or a semiconductor element. Heat generating element on the top, the heat generating element is a circuit for excluding the heat from the heat dissipation film, the heat dissipation film installed on the edge of the circuit board, the heat dissipation film surrounding the entire circuit element area, or the circuit element area exclusion The heat dissipation film on any part of the board can be quickly discharged from the fan structure according to the airway of the fan structure itself, but this method is a method that guides the airflow after conducting heat, and directly generates the heat. Since the heat is not radiated to the element, the heat radiation effect is limited.

また、当該回路基板の放熱フィルム上にも、ファン構造の一部の気道として、多数の開口が形成されるが、当該開口が直接に気流を発熱素子へ案内することではないため、放熱の効果は、依然として、良いものではないから、一般の、従来の放熱構造は、ユーザーの需要を満足できない。 In addition, a large number of openings are formed on the heat dissipation film of the circuit board as a part of the airway of the fan structure. However, since the openings do not directly guide the airflow to the heating element, the heat dissipation effect However, it is still not good, so the general, conventional heat dissipation structure cannot satisfy the user's demand.

本考案の目的は、一般の、従来の放熱構造において、放熱効果の改善が制限される問題と、開口が直接に気流を発熱素子へ案内していない問題とを改善して、ユーザーの需要を満足させるものを提供する。 The purpose of the present invention is to improve the problem that the improvement of the heat dissipation effect is limited in the general conventional heat dissipation structure and the problem that the opening does not directly guide the air flow to the heat generating element, and the demand of the user is improved. Provide a satisfying one.
