Background technique

By the way, the world today is in an era of rapid development of information technology. Whether it is an enterprise or an individual, most of them rely on electronic computers to handle affairs, which also makes people have higher and higher requirements for the computing speed of electronic computers. With the With the improvement of high-tech industry, the operating frequency and speed of many electronic components (such as: central processing unit, south bridge chip and north bridge chip, etc.) are constantly increasing, which in turn increases the heat generated by electronic components. Due to the high temperature, it is easy to It leads to the aging of electronic components and shortens the service life of electronic components. Therefore, the industry has developed many heat dissipation modules in order to dissipate the heat of electronic components in real time and fully.

3. In order to enhance the heat dissipation effect of the heat dissipation module 1, the industry usually uses a fan to match the heat dissipation module 1. After the heat dissipation fins 10 are assembled into the heat dissipation module 1, only two sides are provided with openings, so that the fan The location of the opening is limited to the vicinity of the opening, so that the industry has increased a lot of restrictions when planning the layout of the electronic circuit of the product.

To sum up, it can be known that the heat dissipation module 1 has many practical problems, so how to design a heat dissipation fin that can be easily assembled into a heat dissipation module to solve the above problems has become a problem for manufacturers of heat dissipation modules and It is an important topic that designers study hard and urgently need to be solved.
