Detailed ways

The implementation of the present utility model is described below through specific examples, and those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The utility model can also be implemented or applied through other different specific examples, and various modifications and changes can be made to the details in this specification based on different viewpoints and applications without departing from the spirit of the utility model.

Please refer to FIG. 2 , which is a schematic structural diagram of a casing 2 of the present invention. As shown in the figure, the casing 2 of the present utility model is supplied for a server in this embodiment, including a casing body 20 and an accommodating frame 21 . The accommodating frame 21 accommodates the cooling fan 30 having an air inlet 31 , an air outlet 32 corresponding to the air inlet 31 , and a plurality of fixing holes 33 .

The casing body 20 has a first accommodating space 22 for accommodating the electronic component 40 inside, and an opening 200 is provided on the wall of the casing body 20 adjacent to the electronic component 40, wherein the opening 200 is an existing casing The opening for installing the cooling fan 30 and exposing the air outlet 31, and in this embodiment, its size should be sufficient for the cooling fan 30 to pass through the opening 200 from the casing body 20 and be arranged in the receiving frame Within 21.

The accommodating frame 21 is located at the edge corresponding to the opening 200 and is inclined toward the electronic component 40, presenting a hollow columnar structure, which has a second accommodating space 211 for accommodating the cooling fan 30 inside, when the aforementioned cooling fan 30 slides in from the opening 200 and is placed in the housing frame 21 to form an air passage from the vent to the air inlet 31 of the cooling fan 30 , and the housing frame 21 is opposite to the opening 200 The wall is inclined so that the air inlet 31 of the cooling fan 30 faces the electronic component 40 .

In this way, the heat dissipation fan 30 can directly extract the hot air flow adjacent to the upper part of the electronic component 40, such as memory, as shown by the arrow in the figure, which is different from the air flow extracted in the prior art far away from the heating element, which greatly improves the heat dissipation efficiency.

Please refer to FIG. 3A and FIG. 3B together. The accommodating frame 21 has a plurality of stoppers 210 for stopping the cooling fan 30.
