DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: A high-efficiency heat dissipation server, such as Figure 1-4 As shown, a shell 1 with an upper opening structure is provided, a cover plate 2 is detachably fixedly provided at the opening of the shell 1, a plurality of interfaces 3 are provided at the front end of the shell 1, and the server communicates and exchanges data with other devices, systems or networks through the interfaces 3; a plurality of first air inlet holes that are transparent to the left and right are provided at the left end of the shell 1, and the plurality of first air inlet holes together form a first air inlet net 4, and the plurality of interfaces 3 are respectively located at the front and rear of the first air inlet net; a plurality of second air inlet holes that are transparent to the left and right are provided at the right end of the shell 1, and the plurality of second air inlet holes together form a second air inlet net 5;

[0024] A plurality of hardware components are fixedly arranged inside the shell 1. The hardware components include various parts. The plurality of hardware components work together to support the computing, storage and network functions of the server. The hardware components will generate heat during operation. Two first centrifugal fans 6 are fixedly arranged at a front-to-back interval on the top of the shell 1. The first centrifugal fan 6 is a centrifugal fan, also known as a centrifugal fan or a radial fan. The first centrifugal fan 6 is characterized in that the impeller is based on the principle of centrifugal force. Air is sucked into the fan by rotating the impeller and discharged in a centrifugal direction. For technicians in the relevant field, the first centrifugal fan 6 belongs to a well-known technology, so no further elaboration is made. The plurality of hardware components are respectively located between the first centrifugal fan 6 and the first air inlet net 4 and between the first centrifugal fan 6 and the second air inlet net 5. The air inlet of the first centrifugal fan 6 faces downward, and the air outlets of the two first centrifugal fans 6 are oppositely arranged. The air outlets of the two first centrifugal fans 6 pass through the front and back sides of the shell 1 respectively and are connected to the outside.

[0025] By arranging the first centrifugal fan 6 at the center of the shell 1, the wind in the shell 1 can enter from the first air inlet net 4 and the second air inlet net 5 at the left and right ends of the shell 1 respectively, and be discharged through the first centrifugal fan 6 after heat exchange with the hardware components, so as to achieve the purpose of heat dissipation of the server in a double air inlet manner, which not only can improve the heat dissipation capacity of the server, but also can avoid the wind becoming hot when passing through the heat dissipation components at the rear, resulting in poor heat dissipation conditions for the hardware components at the rear, compared with the front air intake and rear air exhaust manner; at the same time, the two-way air intake can more evenly deliver cold air to all hardware components, reduce the formation of local hot spots, and the air outlets of the two first centrifugal fans 6 are located in the center of the left and right sides of the shell 1, which not only does not affect the up and down stacking installation method of the server, but also is far away from the first air inlet net 4 and the second air inlet net 5, so as to avoid the exhausted hot air being re-inhaled into the server, thereby avoiding affecting the heat dissipation effect of the server.

[0026] Two second centrifugal fans 7 are fixedly provided at the inner bottom of the shell 1. The second centrifugal fans 7 have the same structure as the first centrifugal fans 6 and are both centrifugal fans, so no further details are given. The second centrifugal fans 7 are centrally arranged on the left and right sides, with the air inlet of the second centrifugal fans 7 facing upwards. The second centrifugal fans 7 and the first centrifugal fans 6 are staggered front and back, and the air outlets of the two second centrifugal fans 7 are oppositely arranged. The air outlets of the second centrifugal fans 7 are fixedly connected and connected with air ducts 8, and the ends of the two air ducts 8 away from the second centrifugal fans 7 respectively pass through the front and rear sides of the shell 1 and are connected to the outside.

[0027] The second centrifugal fan 7 can enhance the suction intensity during the heat dissipation process of the server and improve the heat dissipation capacity of the server. At the same time, the second centrifugal fan 7, which is staggered front and rear with the first centrifugal fan 6, can avoid the air suction ports being opposite to each other and affecting each other's air suction. At the same time, the air outlet of the second centrifugal fan 7 is located in the middle of the left and right sides of the side of the shell 1 through the air duct 8, which not only does not affect the up and down stacking installation method of the server, but also is away from the first air inlet net 4 and the second air inlet net 5, avoiding the exhaust hot air from being re-inhaled into the server, thereby avoiding affecting the heat dissipation effect of the server.

[0028] An air outlet of the first centrifugal fan 6 and an end of the air duct 8 away from the second centrifugal fan 7 are both fixedly provided with an air outlet window 9, which can prevent large particles of debris from entering the first centrifugal fan 6 or the second centrifugal fan 7.

[0029] A partition 10 is fixedly provided in the shell 1. The partition 10 is arranged in the middle of the front and rear parts, and is located between the front and rear second centrifugal fans 7. The partition 10 can isolate the two second centrifugal fans 7 in space to avoid the influence of each other's air suction.

[0030] A plurality of first fans 11 arranged at intervals front to back are fixedly provided in the shell 1, and the first fans 11 are located on the right side of the first air inlet net 4; a plurality of second fans 12 arranged at intervals front to back are fixedly provided in the shell 1, and the second fans 12 are located on the left side of the second air inlet net 5; the first fans 11 can force air to enter from the first air inlet net 4 and pass through the hardware components, and the second fans 12 can force air to enter from the second air inlet net 5 and pass through the hardware components, thereby improving the heat dissipation performance of the server and preventing air from entering only from the air inlet on the side through which air can easily pass.

[0031] A first mounting ring 13 is fixedly provided at the left end of the shell 1, the first air inlet net 4 is located on the right side inside the first mounting ring 13, and a first dust filter screen cover 14 with a right opening structure is mounted on the first mounting ring 13; a second mounting ring 15 is fixedly provided at the right end of the shell 1, the second air inlet net 5 is located on the left side inside the second mounting ring 15, and a second dust filter screen cover 16 with a left opening structure is mounted on the second mounting ring 15; the aperture of the first dust filter screen cover 14 is smaller than the first air inlet hole, and the aperture of the second dust filter screen cover 16 is smaller than the second air inlet hole, which can intercept large particles of dust and prevent dust from causing a decrease in the heat dissipation performance of the server, and multiple surfaces of the first dust filter screen cover 14 and the second dust filter screen cover 16 are provided with mesh holes, which increases the air intake and prevents air intake blockage caused by too small mesh apertures.

[0032] Working principle: When the server is dissipating heat, the first fan 11 draws in external cold air from the first air inlet network 4, and after absorbing heat through the hardware components, the hot air is discharged through the first centrifugal fan 6 and the second centrifugal fan 7. The second fan 12 draws in external cold air from the second air inlet network 5, and after absorbing heat through the hardware components, the hot air is discharged through the first centrifugal fan 6 and the second centrifugal fan 7 to dissipate heat for the server.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
