1. Field of the Invention
The invention relates in general to a circuit module and an electronic device using the same, and more particularly to a circuit module with a fan and an electronic device using the same.
2. Description of the Related Art
Electronic products which have reached a mature state are now widely and frequently used by people. Since electronic products are driven by electrical power, it is inevitable that heat will be generated during the use of electronic products. In general, the operating performance of the electronic products operating in a high-temperature environment is inferior to the operating performance of the electronic products operating in a low-temperature environment. Thus, electronic products must dissipate the generated heat to avoid the temperature of the operating environment being too high and resulting in inferior performance. Therefore, the current electronic products, such as computers, are normally equipped with a fan for dissipating the heat to reduce the internal temperature of the electronic products lest the operating performance of the electronic products should deteriorate. Therefore, how to dispose the fan inside the mechanism of the electronic products efficiently and effectively so as to reduce the use of facility and labor has become an imminent task to the industries.
The invention is directed to a circuit module and an electronic device using the same. A fan is buckled on a circuit board, and is thus disposed inside the mechanism quickly and effectively.
According to a first aspect of the present invention, an electronic device is provided. The electronic device includes a mechanism, a circuit module and a fixing element. The circuit module is disposed inside the mechanism. The circuit module includes a circuit board and a fan. The circuit board has at least one edge and a fixing hole. The fan has a first lateral side and a second lateral side. The first lateral side has a first hook buckled on the edge. The second lateral side has at least one screwed board, wherein the screwed board has a screwed hole. The fixing element is screwed on the screwed hole and the fixing hole to screw the fan on the circuit board.
According to a second aspect of the present invention, a circuit module is provided. The circuit module is disposed inside a mechanism of the electronic device. The circuit module includes a circuit board and a fan. The circuit board has at least one edge and a fixing hole. The fan has a first lateral side and a second lateral side. The first lateral side has a first hook buckled on the edge. The second lateral side has at least one screwed board, wherein the screwed board has a screwed hole. The screwed hole is further screwed on the fixing hole via the fixing element to screw the fan on the circuit board.
The above and other aspects of the invention will become better understood with regard to the following detailed description of the preferred but non-limiting embodiment(s). The following description is made with reference to the accompanying drawings.
Referring to
The electronic device 1000 of the present embodiment of the invention is disclosed below. The electronic device 1000 includes a mechanism 1100, a circuit module 1200, and a fixing element 1300. The circuit module 1200 includes a circuit board 1210 and a fan 1220. The circuit board 1210 has at least one edge 1211 and a fixing hole 1212. The fan 1220 is screwed on the circuit board 1210 and has a first lateral side 1221 and a second lateral side 1222. The second lateral side 1222 is substantially opposite to the first lateral side 1221. The first lateral side 1221 has a first hook 1221A buckled on the edge 1211. The second lateral side 1222 has at least one screwed board 1222A having a screwed hole 12228. The fixing element 1300 is screwed on the screwed hole 1222B and the fixing hole 1212 to screw the fan 1220 on the circuit board 1210. The fixing element 1300 can be realized by such as a screw.
The relative positions between the screwed board 1222A and the first hook 1221A of the present embodiment of the invention are disclosed below. As indicated in
Since the relative positions between the screwed board 1222A and the first hook 1221A are substantially diagonal to each other, the fan 1220 can be fixed on the circuit board 1210 by the first hook 1221A and the screwed board 1222A alone. Thus, the fan 1220 only needs one screwed hole 12228 in addition to the first hook 1221A for the fixing element 1300 to fix the fan. That is, in comparison to the conventional method which requires many screws to screw the fan on the circuit board, the practice of fixing the fan 1220 on the circuit board 1210 according to the present embodiment of the invention reduces the quantity of the fixing element 1300. Thus, the circuit module 1200 of the electronic device 1000 of the present embodiment of the invention not only reduces the manufacturing cost, but also reduces the labor and manufacturing time required for screwing the fan 1220 on the circuit board 1210, so as to reduce the product price and enhance product competiveness.
To enhance the fixing effect of fixing the fan 1220 on the circuit board 1210, the elasticity effect of fixing the fan 1220 on the circuit board 1210 can be increased to avoid the first hook 1221A being damaged due to the negligence during assembly. For example, the first lateral side 1221 of the fan 1220 further has a second hook which can be buckled on the edge 1211. Thus, the second hook facilitates the fan 1220 to be fixed on the circuit board 1210. Referring to
For the fan 2220 of
Since the first lateral side 2221 of the fan 2220 has the first hook 2221A and the second hook 2221B, the fan 2220 can be more flexibly fixed on the circuit board 1210 to avoid the first hook 2221A and the second hook 2221B being damaged due to the negligence during assembly.
As indicated in
To summarize, the practice of fixing the fan on the circuit board with a large amount of screws will largely increase labor and manufacturing cost as well. In an embodiment of the circuit module and an electronic device using the same of the invention, the relative positions between the screwed board and the first hook are substantially opposite to each other, so that the fan only needs one screwed hole in addition to the hook for the fixing element to fix the fan. In comparison to the practice of fixing the fan with a large amount of screws, the practice of fixing the fan on the circuit board disclosed in the above embodiment of the invention largely reduces the use of fixing element, not only reducing the manufacturing cost, but also reducing the labor and manufacturing time. Thus, the products manufacturing according to the above embodiments of the invention are more competitive than similar products.
In another embodiment, since the first lateral side of the fan has the first hook and the second hook, the fan can be more flexibly fixed on the circuit board, not only avoiding the hooks being damaged but also increasing the stability of fixing the fan on the circuit board.
While the invention has been described by way of example and in terms of the preferred embodiment(s), it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
