Description

Technical Field

[0001] The utility model relates to the technical field of data processors, in particular to a gigabit network data processor. Background Art

[0002] As data centers become data-centric, CPU performance has lagged far behind the growth rate of data. GPU-accelerated computing has become the mainstay of computing, greatly improving the computing performance of single processors and single machines. The traditional way of using CPUs to handle infrastructure operations such as security, communications, storage, and virtualization in data centers has gradually become a bottleneck for computing performance growth, and the conflict between computing and infrastructure support functions on CPU resources has become increasingly intense.

[0003] For example, the authorization announcement number "CN216133988U" is named as a network data processor that is easy to install. Although it is provided with nine groups of lower bases and nine groups of upper sockets, the nine groups of upper bases and nine groups of lower bases can effectively facilitate information transmission, so that the nine groups of upper sockets and nine groups of lower bases form nine groups of channels, which is convenient for the network data processor to transmit information. Due to the use of a docking and splicing installation method to complete the installation combination of the network data processor, the multiple sockets are plugged into each other and rely on the friction force on the inner side of the connecting sockets to achieve the fixing effect. When the network data processor is pulled or taken by external force, the bottom base is easily separated from the upper socket due to the influence of gravity, which makes the network data processor easy to open and expose the internal processor circuit components, which in turn leads to the installation and fixing effect of the easy-to-install network data processor is not ideal.

[0004] At the same time, the existing easy-to-install network data processors are designed with a nearly sealed shell to support the internal components of the network data processor. Since it is difficult for the network data processor to accumulate heat when working, the heat gradually accumulates and increases in the sealed shell, which will cause the internal temperature of the shell of the easy-to-install network data processor to be relatively high. In the high-temperature working environment, the circuit mainboard is easily overwhelmed by the work and causes the circuit components to burn out or the aging of the circuit equipment to accelerate, thereby resulting in the problem of reduced service life of the easy-to-install network data processor.

DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings:

[0029] See also Figure 1-7 A gigabit network data processor comprises a mounting plate 1, a data processor body 2 and a processor interface 3, wherein the data processor body 2 is movably mounted above the mounting plate 1, and a data processor firmly fixed locking structure 4 is provided above the mounting plate 1, wherein the data processor firmly fixed locking structure 4 comprises a vertical plate 41, a positioning block 42 and a protrusion 43, wherein two positioning blocks 42 are fixedly mounted on both sides above the mounting plate 1, and two protrusions 43 are slidably connected to the inner sides of the two positioning blocks 42, wherein the protrusions 43 are at the lower end of the vertical plate 41, and the protrusions 43 can be inserted into the cavity inside the positioning block 42, and the two vertical plates 41 are fixedly mounted above the two protrusions 43;

[0030] An extrusion plate 46 is fixedly connected to one side of the top of the two vertical plates 41. When the vertical plates 41 are fixed inside the bottom positioning block 42, the vertical plates 41 will pull the extrusion plate 46 to fall to the top of the data processor body 2, connecting and fixing the data processor body 2 and the lower mounting plate 1. A limiting seat 44 is fixedly installed on the inner side of the two positioning blocks 42. The limiting seat 44 is used to limit the falling depth of the protrusion 43. A sealing layer 45 is fixedly installed above the two positioning blocks 42. The sealing layer 45 is made of rubber material. The sealing layer 45 is wrapped around the top edge of the limiting seat 44 to reduce dust entry. The inner wall of the sealing layer 45 is slidably connected to the outer wall of the vertical plate 41.

[0031] The inner side of the positioning block 42 is provided with a clamping data processor disassembly structure 5, which includes an active cavity 51, a clamping slot 53 and a slide 54. The two active cavities 51 are fixedly opened on both sides of the inner wall of the positioning block 42, and the interior of the two active cavities 51 is movably connected with a docking ball 52. The two clamping slots 53 are fixedly opened on the outer wall of the protrusion 43, and the inner sides of the two clamping slots 53 are movably connected with the docking ball 52. The two slides 54 are fixedly installed on both sides of the outer wall of the positioning block 42. When the protrusion 43 is fixed, the protrusion 43 can be directly manually moved. 3 is inserted into the positioning block 42. At this time, the protrusion 43 drives the two side slots 53 to enter the positioning block 42. When the slots 53 are relative to the movable chambers 51 on both sides, the docking ball 52 will roll to the inside of the slots 53. The docking ball 52 is inside the slots 53. At this time, when the protrusion 43 is pulled upward, the docking ball 52 increases the outer diameter of the protrusion 43, so that the docking ball 52 is pressed against the top of the positioning block 42. At this time, the position of the protrusion 43 is locked by the docking ball 52 and cannot be pulled out. The inner sides of the two slideways 54 are slidably connected to two magnetic blocks 55.

[0032] The outer walls of the two magnetic blocks 55 are fixedly installed with a lower pull rod 56, and the inner sides of the two lower pull rods 56 are slidably connected to the outer wall of the positioning block 42. When the protrusion 43 and the positioning seat 42 need to be removed, the operator manually pushes the two lower pull rods 56 to slide downward, and the lower pull rods 56 drive the magnetic blocks 55 on both sides to move downward along the slide 54. When the position of the magnetic block 55 is at the same height as the docking ball 52, the docking ball 52 made of metal iron will be attracted back into the active cavity 51, and the protrusion 43 can be quickly pulled out without the restriction. The outer sides of the two positioning blocks 42 are movably connected to the outer walls of the data processor body 2 on both sides, and the lower ends of the two extrusion plates 46 are movably connected to the top of the data processor body 2. The inner side of the mounting plate 1 is threadedly connected to multiple bolts 92, and the outer sides of the multiple bolts 92 are threadedly connected to multiple mounting nuts 91. The mounting plate 1 can be connected to the position where it needs to be installed through the multiple bolts 92 around it, and then the mounting nuts 91 are sleeved on the outer sides of the bolts 92, and the fixing is achieved by the extrusion force of the mounting nuts 91;

[0033] The protrusion 43 is at the lower end of the vertical plate 41, and the protrusion 43 can be inserted into the cavity inside the positioning block 42. When the vertical plate 41 is fixed inside the bottom positioning block 42, the vertical plate 41 will pull the extrusion plate 46 to fall to the top of the data processor body 2, and the data processor body 2 and the lower mounting plate 1 are connected and fixed. When the slots 53 are relative to the active cavities 51 on both sides, the docking ball 52 will roll to the inside of the slots 53. The docking ball 52 is inside the slots 53. At this time, when the protrusion 43 is pulled upward, the docking ball 52 will increase the outer diameter of the protrusion 43, so that the docking ball 52 is tightly pressed against the top of the positioning block 42. At this time, the position of the protrusion 43 is locked by the docking ball 52 and cannot be pulled out. The use of a firm and easy-to-separate and disassembled extrusion plate fixing structure makes the connection between the data processor body 2 and the lower mounting plate 1 more secure, thereby improving the fixing effect of the Gigabit network data processor.

The inner side of the exhaust cavity 63 is threadedly connected with two screws 64. When ventilation and heat dissipation work needs to be met, the fan frame 62 with the inner induced draft fan 65 is vertically placed into the reserved hole 61, and then the screws 64 on both sides are used to rotate and fix it;

[0035] After the power supply is connected, the induced draft fan 65 rotates, and the wind enters the inside of the data processor body 2 along the dustproof net 66, and then is discharged along the top exhaust cavity 63 with the heat. The inner sides of the two screws 64 are connected to the inner thread of the reserved hole 61. A plurality of heat sinks 7 are fixedly installed on the top of the outer wall of the data processor body 2. The heat sink 7 is made of copper.

The inner side of the exhaust cavity 63 is threadedly connected with two screws 64. When ventilation and heat dissipation are required, the fan frame 62 with the inner induced draft fan 65 is vertically placed into the reserved hole 61, and then the screws 64 on both sides are rotated to install and fix. After connecting the power supply, the induced draft fan 65 rotates, and the wind enters the data processor body 2 along the dustproof net 66, and then the heat is discharged along the top exhaust cavity 63. The heat sink 7 is made of copper sheets made of metal copper. The heat sink 7 is provided with a plurality of side-by-side to increase the contact area with the outside world and accelerate the heat dissipation effect. By setting up the wind and the heat sink at the same time, the ventilation and heat dissipation are accelerated while the heat dissipation and cooling speed are accelerated, ensuring that the service life of the Gigabit network data processor is not easily reduced.

[0037] See also Figure 1-7 A processor control device support and reinforcement structure 8 is provided on the inner side of the data processor body 2.

[0038] Working principle:

[0039] When using a Gigabit network data processor to collect and process Gigabit network data at high speed:

[0040] Stable installation and fixing structure of Gigabit network data processor:

[0041] First, the protrusion 43 is at the lower end of the vertical plate 41, and the protrusion 43 can be inserted into the cavity inside the positioning block 42. When the vertical plate 41 is fixed inside the bottom positioning block 42, the vertical plate 41 will pull the extrusion plate 46 to fall to the top of the data processor body 2, connecting and fixing the data processor body 2 and the lower mounting plate 1;

[0042] When fixing the protrusion 43, the protrusion 43 is directly manually inserted into the positioning block 42. At this time, the protrusion 43 drives the two side slots 53 to enter the positioning block 42. When the slots 53 are relative to the movable cavities 51 on both sides, the docking ball 52 will roll to the inside of the slots 53. The docking ball 52 is inside the slots 53. At this time, when the protrusion 43 is pulled upward, the docking ball 52 increases the outer diameter of the protrusion 43, so that the docking ball 52 is pressed against the top of the positioning block 42. At this time, the position of the protrusion 43 is locked by the docking ball 52 and cannot be pulled out.

[0043] When the protrusion 43 and the positioning seat 42 need to be removed, the operator manually pushes the two lower pull rods 56 to slide downward, and the lower pull rods 56 drive the magnetic blocks 55 on both sides to move downward along the slide 54. When the magnetic blocks 55 are at the same height as the docking ball 52, the docking ball 52 made of metal iron will be attracted back into the active cavity 51, and the protrusion 43 can be quickly pulled out without being restricted.

[0045] The dustproof net 66 can be made of a stainless steel mesh plate that can filter and prevent large pieces of dust from entering the data processor body 2. The inner side of the exhaust cavity 63 is threadedly connected with two screws 64. When ventilation and heat dissipation are required, the fan frame 62 with the inner induced draft fan 65 is vertically placed into the reserved hole 61, and then the screws 64 on both sides are rotated to install and fix. After connecting the power supply, the induced draft fan 65 rotates, and the wind enters the data processor body 2 along the dustproof net 66, and then the heat is discharged along the top exhaust cavity 63. The heat sink 7 is made of copper sheets made of metal copper, and a plurality of heat sinks 7 are arranged side by side to increase the contact area with the outside world and accelerate the heat dissipation effect;
