Electronic device

The present invention relates to an electronic device, and more particularly to an electronic device free of a fan back plate.

As electronic devices gradually move toward the design concept of "light, thin, short, and small", the size of electronic components inside them tends to be miniaturized. However, as the volume of electronic components tends to be miniaturized, the density per unit area increases, so the amount of heat generated by the related electronic components also increases. Because the excessive temperature will seriously affect the stability and efficiency of the operation of the electronic device, and the life of the electronic component is shortened, the heat sink has become an indispensable device for the electronic device.

Taking a server as an example, in general, the heat dissipation requirement of the server is high. Therefore, a fan array composed of a plurality of fans is generally provided inside the server to improve the heat dissipation capability of the server. The fan array is generally assembled to the server casing through the fan frame, and the fan back plate in the form of a circuit board is generally transferred to the motherboard in the server, thereby enhancing the fan array and the server. Assembly efficiency.

Although the fan backplane can improve the assembly efficiency between the fan array and the motherboard, the cost of the fan backplane is high, which makes it difficult to reduce the cost of the server, which may reduce the market competitiveness of the server.

In addition, the setting of the fan backboard additionally occupies the storage space of the server, which causes a waste of space, which makes it difficult to further reduce the size of the server.

Therefore, how to balance the assembly efficiency of the fan array and the assembly cost and the waste of the server accommodation space will be one of the problems that the R&D personnel should solve.

The present invention provides an electronic device that combines the assembly efficiency and assembly cost of the fan array with the improvement of waste in the server housing space.

The electronic device disclosed in the present invention comprises a casing, a motherboard and a fan module. The motherboard is placed in the chassis. The fan module is disposed in the casing. The fan module includes a frame, a plurality of adapters, and a transmission component. The frame includes a base and two side panels. The base has a top surface and a bottom surface. The two side plates are connected to opposite sides of the base and the top surface of the base and the two side plates together form at least one air passage. One of the two side plates has a cable management port, and the bottom surface of the base has a cable management slot and a plurality of cable management structures. One end of the cable management slot is connected to the cable management port. These cable management structures are adjacent to the cable management slots. These adapters are mounted on the base of the frame. The adapter includes a first electrical port and a second electrical port. The first electrical connection port is orthogonal to the insertion direction of the second electrical connection port. The first electrical connector is attached to the bottom surface of the base. The second electrical connector is inserted into the base and protrudes from the top surface of the base and is located in the airflow path. The transmission component includes a plurality of third electrical connections, a fourth electrical connection, a fifth electrical connection, and a wire. The wire connects the third electrical connection port and the fourth electrical connection port, and connects the third electrical connection port and the fifth electrical connection port. The third electrical connections are respectively detachably inserted into the first electrical connections. The fourth electrical connection port and the fifth electrical connection port are located at one end of the wire away from the third electrical connection ports. The transmission component passes through the frame of the cable management structure and the guiding cable of the cable management slot, so that the fourth electrical connection port and the fifth electrical connection port are located outside the frame and are detachably inserted on the motherboard. Each of the fan units has a sixth electrical port. The fan unit is located in the airflow path, and the sixth electrical port is detachably inserted into the second electrical port, so that the fan unit is electrically connected to the motherboard through the transmission component.

According to the electronic device disclosed in the above embodiments, since the fan unit is directly inserted into the motherboard through the adapter and the transmission component, rather than being connected through another circuit board, the manufacturing cost of the electronic device can be reduced to enhance the market. Competitiveness.

Moreover, since there is no need to additionally set the circuit board, the utilization of the storage space of the server can be optimized to improve the problem that the circuit board wastes the storage space of the server.

The above description of the present invention and the following description of the embodiments are intended to illustrate and explain the principles of the invention, and to provide a further explanation of the scope of the invention.
