Description

cooling system

The invention relates to a heat dissipation system, in particular to a heat dissipation system for adjusting a position in a computer casing.

In today's computer systems, special attention must be paid to the problem of heat dissipation in the body to avoid damage to the computer system caused by excessive temperature in the computer system. Especially for CPUs or memories that are most prone to high temperatures. Taking a computer system as a server (for example, a 1U server) as an example, since it is necessary to turn on the computer for a long time to continuously execute the computer system, a better heat dissipation system is needed to avoid the temperature of the computer system being too high.

Therefore, in the prior art, a heat dissipation system for a computer system of a server has been disclosed. Next, please refer to FIG. 1 , which is a structural diagram of a prior art heat dissipation system. The computer casing 90 of the prior art is used in a computer system of a server, and is internally provided with a heat dissipation system 91, an air hood 92, and an element 93 of the computer system. The heat dissipation system 91 is fixed to the computer casing 90. The heat dissipation system 91 includes a plurality of fan receiving slots 911 and a plurality of fans 912. The plurality of fans 912 of the heat dissipation system 91 are directly opposite the components 93 of the computer system to provide airflow, and the air hood 92 is used to concentrate the flow of air.

However, since different computer systems have different specifications, the position of the fan 912 may not be able to include all of the components 93 of the computer system. As shown in FIG. 1, if the heat dissipation system 91 has only four fans 912, the airflow derived by the four fans 912 cannot cover the entire range of the components 93 of the computer system. There must be five fans 912 to completely cover the full range of components 93 of the computer system, as an additional fan 912 would be required. Moreover, in order to match the number of fans 912 and the concentrated airflow, the air guiding hood 92 needs to be specially designed to have a better conduction effect. It can be seen that the prior art heat dissipation system 91 increases the manufacturing cost.

It is therefore necessary to invent a new heat dissipation system to address the lack of prior art.

The main object of the present invention is to provide a heat dissipation system for the function of adjusting the position in a computer casing to achieve a better heat dissipation effect.

In order to achieve the above object, the heat dissipation system of the present invention is disposed in a computer casing. The heat dissipation system includes at least one fan, a plurality of fan receiving slots, a slide rail and a fixing member. A plurality of fan accommodating slots are used to place the fan. The sliding rail system cooperates with a plurality of fan receiving slots to allow a plurality of fan receiving slots to slide on the sliding rails. The fixing member is configured to fix a plurality of fan receiving slots when the plurality of fan receiving slots slide to a certain point, so that the fan can provide a wind flow in the computer casing to achieve the heat dissipation effect.

The above and other objects, features and advantages of the present invention will become more <

Please refer to FIG. 2 to FIG. 3 for a schematic diagram of a heat dissipation system, wherein FIG. 2 is a schematic diagram of an embodiment of the heat dissipation system of the present invention fixed to a first fixed point, and FIG. 3 is a heat dissipation system of the present invention fixed to a second fixed point. Schematic diagram of an embodiment.

The heat dissipation system 10 of the present invention is disposed in a computer casing 1 for providing a better heat dissipation environment for the components 61 (shown in FIG. 4) of the computer system disposed in the computer casing 1. The heat dissipation system 10 is particularly useful for computer systems that require uninterrupted operation, such as computer systems for servers, such as 1U servers, but the heat dissipation system 10 of the present invention is not limited thereto.

The heat dissipation system 10 includes a plurality of fan receiving slots 11, a fan 12, a slide rail 20, and a fixing member 31 for fixing a plurality of fan receiving slots 11. In an embodiment of the present invention, the plurality of fan receiving slots 11 are fixed together and can slide at the same time, but the invention is not limited thereto. The plurality of fan receiving slots 11 can also be individually adjusted in position. The fan accommodating slot 11 is configured to place at least one fan 12, wherein the number of the fan accommodating slots 11 is greater than or equal to the number of the fans 12, that is, the present invention does not limit the fan 12 to be fully filled with the fan. The slot 11 can adjust the number and placement of the fan 12 as needed. The air outlet of the fan 12 is directly facing the component 61 of the computer system to provide air flow to the component 61 of the computer system for heat dissipation.

The plurality of fan receiving slots 11 cooperate with the slide rails 20 such that the plurality of fan receiving slots 11 can slide on the slide rails 20. In an embodiment of the present invention, the fan receiving slot 11 slides only between the first fixed point 21 and the second fixed point 22 on the slide rail 20, but the invention is not limited thereto. The present invention can also set the fan receiving groove 11 to slide between any fixed points on the slide rail 20. The distance between the first fixed point 21 and the second fixed point 22 is the width of the half fan 12. In the present embodiment, the fixing member 31 is a bolt, but the present invention is not limited thereto. The fixing member 31 is used for locking the plurality of fan receiving slots 11 to the first fixed point 21 or the second fixed point 22, but the invention is not limited to being fixed to the first fixed point 21 or the second fixed point 22. With the above structure, the air outlets of the plurality of fans 12 can be adjusted to face the component 61 of the computer system.

On the other hand, when the plurality of fan receiving slots 11 slide between the first fixed point 21 and the second fixed point 22, the plurality of fan receiving slots 11 and the side of the computer casing 1 must have a gap. The voids cause the wind to flow back and reduce the heat dissipation efficiency of the heat dissipation system 10. Therefore, the fan receiving slot 11 and the side of the computer casing 1 further have an convection member 41 for blocking the flow of the air. In FIG. 2, when the fan receiving slot 11 is fixed to the first fixed point 21, an antrating member 41 is disposed between the left side of the fan receiving slot 11 and the side of the computer casing 1 to block the airflow return. Similarly, when the fan receiving groove 11 is fixed to the second fixed point 22 in FIG. 3, the right side of the fan receiving groove 11 is provided with a flow restricting member 41 to block the flow of the air.

Finally, please refer to FIG. 4, which is an architectural diagram of an embodiment of the heat dissipation system and the components of the computer system of the present invention.

According to the above structural description, the fan accommodating groove 11 of the present invention can face the plurality of fans 12 all facing the component 61 of the computer system according to the position of the component 61 of the computer system. The component 61 of the computer system is a central processing unit or a memory card or the like, but the invention is not limited thereto. And in the preferred embodiment of the invention, the heat dissipation system 10 can be coupled to the air hood 51. The air hood 51 is matched with the plurality of fan accommodating slots 11 and directly disposed at the air outlet of the fan 12, so that the wind flow generated by the fan 12 can all flow through the component 61 of the computer system to achieve an optimal heat dissipation effect.

It can be seen from the above description that the heat dissipation system 10 of the present invention can save the number of the fans 12, and the shape of the air guiding cover 51 does not need to be specially designed, which can save a lot of manufacturing costs.

To sum up, the present invention, regardless of its purpose, means and efficacy, shows its distinctive features of the prior art. You are requested to review the examination and express the patent as soon as possible.
