Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of server, concretely relates to a server based on composite cooling. BACKGROUND

[0002] As the core equipment of modern information technology system, servers are widely used in data storage, network management and computing processing fields. In the scenario of high-density computing and long-time running, the server cooling problem is particularly important. A large amount of heat is generated when the server is working, and if the heat is not dissipated in time, the device will overheat, which will affect the running efficiency and even damage the core components. Therefore, the cooling design of the server plays a key role in improving the performance of the device, prolonging the service life and saving energy.

[0003] At present, the server cooling mainly relies on single air cooling or water cooling. The traditional air cooling system removes heat by air flow brought by the fan, but the air cooling efficiency is often insufficient in the case of high heat density, and local hot spots are easily formed. While the separate water cooling method exports heat through circulating coolant, although the cooling efficiency is higher, the device structure is complex and the cost is higher. At the same time, the limitation of single cooling method cannot meet the higher requirement of high-performance server on cooling effect.

[0004] In order to solve the problems existing in the prior art, some researches begin to try to combine the composite cooling method of air cooling and water cooling, and improve the overall cooling effect by combining the advantages of the two cooling methods. However, the current composite cooling device still has some deficiencies in practical application: on the one hand, the structure design of the existing device lacks flexibility and is difficult to adapt to the installation requirements of different servers; on the other hand, the stability of the device in the running process is poor and is easily affected by external factors such as vibration, which affects the cooling effect. UTILITY MODEL CONTENTS

[0006] In order to achieve the above purpose, the utility model provides the following technical scheme:

[0008] Further, the second mounting seat is symmetrically opened with air outlet close to the side of server main body, two the air outlet is placed respectively in the both sides of server main body, the second mounting seat inside is installed with conical flow guide block, and the conical flow guide block is equally divided into two air outlets in the cold air blown out by fan.

[0009] Further, the limiting mechanism includes fixed bolt fixed on the surface of first mounting seat and second mounting seat, and the fixed bolt surface is symmetrically rotatably installed with movable rod.

[0010] Further, the movable rod end inside is provided with clamping convex point, and two the clamping convex point is respectively clamped to the both sides of server main body.

[0011] Further, the movable rod end away from clamping convex point is provided with extrusion rod, and the clamping convex point and extrusion rod are placed respectively on both sides of movable rod rotation axis.

[0012] Further, the first mounting seat and second mounting seat surface are provided with boss, the boss is placed outside fixed bolt, the boss surface is screwed and penetrates with adjusting screw rod, the adjusting screw rod end close to server main body is screwed and installed with conical extrusion block, the conical extrusion block is placed between two extrusion rods, and the conical extrusion block both sides are respectively extruded to two extrusion rods.

[0013] Compared with prior art, the utility model has the advantages that:

[0014] The combination of the water cooling mechanism and the air cooling mechanism solves the problem of low efficiency of the traditional single cooling mode. In a high heat density server operating environment, the combination of the circulating cooling water pipe in the water cooling mechanism and the fan in the air cooling mechanism not only improves the heat dissipation efficiency, but also effectively avoids the generation of local hot spots. The circulating cooling water pipe cooperates with the heat conduction strip to tightly adhere to the surface of the server main body, which can quickly transfer the heat on the surface of the server main body to the cooling liquid. The cold air generated by the fan is guided to the two sides of the server main body through the conical guide block, further improving the cooling effect, and achieving the technical goal of efficient heat dissipation.

[0015] The water cooling mechanism and the air cooling mechanism are respectively installed on the two sides of the server main body, and the combination of the docking groove and the limiting mechanism solves the problem of unstable installation of the cooling device in the prior art. The limiting mechanism cooperates with the fixed bolt, the movable rod and the adjusting screw, and uses the clamping convex points and the tight clamping of the two sides of the server main body and the extrusion effect of the conical extrusion block to ensure that the water cooling mechanism and the air cooling mechanism do not loosen during the operation of the server main body. At the same time, the boss provides additional support, further enhancing the installation stability of the device.

[0016] The cooperation of the pump body in the water cooling mechanism and the fan in the air cooling mechanism solves the problem that the existing cooling device cannot uniformly cool. When the cooling liquid flows in the circulating cooling water pipe, the T-shaped cross section design of the heat conduction strip increases the heat conduction area, thereby improving the heat transfer efficiency. At the same time, the cold air generated by the fan is divided into two air outlets through the conical guide block, so that the cold air uniformly covers the surface of the server main body, and the cooling liquid inside the cooling water pipe can be cooled at the same time. The cooperation of water cooling and air cooling can greatly improve the cooling efficiency and reduce the problem of local overheating caused by uneven heat dissipation during server operation.
