Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1 and 2, an embodiment of a heat dissipation device of the present invention is used for dissipating heat of a GPU, a CPU, or other servers. The heat dissipation device comprises the first fans 1 and the second fans 2, and all the first fans 1 and all the second fans 2 are located on the top wall of the server case, so that the mode of the heat dissipation air channel for up-and-down ventilation of special servers such as a GPU is more met, and the heat dissipation effect is improved.
All the first fans 1 are used for blowing cold air into the server chassis, and the second fans 2 are used for sucking out hot air inside the server chassis. Thereby utilize the cooperation of first fan 1 and second fan 2 to make the cold air realize the circulation in server machine incasement, first fan 1 and second fan 2 all are located the roof of server machine case simultaneously, thereby through the air supply of first fan 1, and the cooperation of induced drafting of second fan 2, make the circulation of cold air in server machine incasement portion more adapt the inside heat dissipation wind channel of GPU, realized that the cold air dispels the heat at server machine incasement top and bottom ventilation mode ground, the radiating efficiency is improved, thereby GPU among the prior art has been solved because of inconsistent with server heat dissipation wind channel and has resulted in the high temperature operation thereby the over temperature performance of falling the frequency reduces the problem of life with the latter.
The first fan 1 and the second fan 2 are both located outside the server case, so that occupation of the first fan 1 and the second fan 2 on the inner space of the server case can be reduced, and influence on installation of parts of the server case is reduced. Meanwhile, the efficiency of heat exchange when the first fan 1 and the second fan 2 are operated can be improved.
The second fan 2 is provided with the wind scooper 21, the second fan 2 can vertically and upwardly extract hot air in the server case when working, and the server case is mainly placed in an up-and-down stacking mode, so that the influence of the hot air extracted by the second fan 2 on the bottom wall of the server case above the server case is reduced, the blowing direction of the second fan 2 can be changed by using the wind scooper 21, and the phenomenon of over-temperature of the chassis of the server case above the same rack is reduced. In this embodiment, the first fan 1 and the second fan 2 can be matched with an original heat dissipation fan in the server chassis, wherein the first fan 1 is located above the original heat dissipation fan, and the cold air sucked by the heat dissipation fan can be pressed into the server chassis by using the first fan 1, so that the cold air can flow in the server chassis, and then the cold air is taken out by the second fan 2 and flows out along the channel of the air guiding cover 21.
The air guiding cover 21 is disposed in a tapered shape, and the sectional area of the air guiding cover 21 increases in a direction approaching the opening of the air guiding cover 21. Thereby, the flow of the hot air extracted by the second fan 2 in the air guiding cover 21 is facilitated, and the heat dissipation efficiency can be improved. In this embodiment, the opening direction of the wind scooper 21 is set toward the direction away from the first fan 1, so as to reduce the influence of the hot air extracted by the second fan 2 on the first fan 1, and meanwhile, the stacked server chassis has a larger space at the side away from the first fan 1, thereby facilitating the discharge of the hot air. The wind scooper 21 is used for limiting the flowing direction of the hot air extracted by the second fan 2 to be different from the direction of the cold air absorbed by the first fan 1, so that the mutual interference of the cold air and the hot air is avoided, and the heat dissipation efficiency is improved.
