[0001] [0002] New Description: [New Technology Field] This creation is related to a fan module, especially one that can greatly increase the airflow of at least one crossflow fan and reduce the volume of the fan module. It can also improve the heat dissipation performance and effectively improve the fan module of the conventional fan blade caused by excessive vibration and abnormal sound. [Prior Art] With the continuous advancement of the electronic technology industry, the transistor density of various types of wafers (such as central processing units, execution units, etc.) has increased, although the data processing speed is getting faster and faster, but the power consumed and generated The heat is relatively increased; in order to make the central processing unit stable, high-efficiency heat dissipation units have become an important issue at present. In order to maintain high-efficiency heat dissipation, the size and weight of the heat-dissipating unit have to be heavier and heavier. However, in the design of notebook computers, tablet computers, smart phones, smart handheld electronic devices, etc., space constraints It has always been the biggest bottleneck in design. Referring to FIG. 1 , a conventional fan module 1 includes a centrifugal fan 10 , a heat pipe 11 , and a heat dissipation unit 12 . The conventional fan module 1 uses a centrifugal fan 10 to drive air flow. The heat of the heat dissipating unit 12 is taken away to achieve the purpose of cooling, and the wind pressure, the air volume of the centrifugal fan 10, and the heat exchange area of the heat dissipating unit determine the performance of the fan module 1; The larger the heat exchange area, the longer the fin length of the heat sink fin, although the heat dissipating unit 12 can discharge the heat better, but the overall length of the fan module is too large due to the increase of the fin length; The light, thin and short view that the notebook computer pursues #单编号A0101 1012005517-0 Page 4 of 19 M430149

In order to achieve the above-mentioned light, thin, short, and small spiritual demands, the operators engaged in related industries have minimized the components as much as possible. Therefore, the size of the centrifugal fan is also miniaturized, but the volume is reduced. Centrifugal fans also have a relatively small flow rate, which greatly affects the heat output, and the miniaturized centrifugal fan produces more vibration and abnormal sound due to the thin blade thickness and large area. Therefore, how to improve the efficiency of the heat dissipation unit without increasing the volume of the heat dissipation unit as much as possible has become the direction of efforts of many related industries. As mentioned above, the conventional disadvantages have the following disadvantages: 1. Large volume; 2. Poor heat dissipation capability; 3. Easy to generate vibration and abnormal sound. Therefore, how to solve the above problems and shortcomings, that is, the creators of the case and the relevant manufacturers engaged in this industry are willing to study the direction of improvement. [New content] Therefore, in order to effectively solve the above problems, the main purpose of the present invention is to provide a fan module in which at least one cross flow fan is disposed in a fan module, which can greatly increase the airflow flow of the cross flow fan and reduce the volume. The second objective of this creation is a fan module that enhances heat dissipation and effectively improves vibration and abnormal sound caused by yaw caused by excessive blade length. In order to achieve the above object, the present invention is a fan module comprising: a heat conducting unit, a heat dissipating unit and at least one cross flow fan, the heat conducting single 10120180^^^^ A0101 page 5 / total 19 pages 1012005517-0 M430149 One end of the element is attached to a heat source, and the heat dissipating unit is connected to the other end of the heat conducting unit, and has an air inlet and an air outlet that communicates with the air inlet.
