Description

Technical Field

[0001] The present application relates to the technical field of liquid cooling devices, and in particular to a liquid-cooled network card module and a server. Background Art

[0002] The network card is one of the most commonly used components in the server, and most of them have low power consumption. Therefore, the heat dissipation for the network card is also quite diverse. In the conventional server design, it is generally equipped with a radiator, and the fan provides air volume for heat dissipation. However, with the rapid development of the server industry, the power consumption of the whole machine is getting higher and higher, and the heat dissipation method of the fan can no longer meet the heat dissipation requirements of the system. At this time, the introduction of a full liquid cooling solution is required, which means no fan, and the heat dissipation method of the network card must also use a cold plate. At present, there are various designs of cold plates for network cards. Some cold plates are directly buckled on the network card, and then connected to the Manifold through a water pipe to achieve the heat dissipation of the network card. Some are heat dissipated by laminating, but each has its own advantages and disadvantages. The laminating heat dissipation method cannot solve the problem of heat dissipation of high-power network cards. The cold plate buckled on the network card will be installed on the chassis due to the limitation of the chassis space, resulting in the need to remove the cold plate before the maintenance plug. This method makes maintenance difficult, increases maintenance costs and affects the user experience. Summary of the invention

[0036] The embodiment of the present application can achieve communication with an external cooling device by providing a water inlet blind plug 121 and a water outlet blind plug 122 at the bottom of the sliding connection block 12. When the sliding connection block 12 is slidably connected to the inner side of the chassis 3, the sliding movement direction of the sliding connection block 12 can be limited, so that the water inlet blind plug 121 and the water outlet blind plug 122 at the bottom of the sliding connection block 12 are connected without falling off.

Therefore, setting the heat conducting plate 114 and the optical module 21 in a one-to-one correspondence connection can realize the rapid transmission of the heat on the network card 2 to the heat conducting plate 114.

[0041] See also Figure 1 The cooling liquid channel 111 is U-shaped, and the cooling liquid channel 111 may also be, for example, S-shaped or C-shaped. The first liquid inlet 112 and the first liquid outlet 113 are located on the same side of the network card cold plate 11, and the heat conducting plate 114 is disposed on the side of the network card cold plate 11 away from the first liquid inlet 112 and the first liquid outlet 113. This arrangement can facilitate the rapid transfer of heat in the heat conducting plate 114 to the coolant in the cooling liquid channel 111.

When the sliding connection block 12 is slidably connected to the inner side of the chassis 3, the sliding movement direction of the sliding connection block 12 can be limited to slide along the vertical limiting slide groove 31, wherein the limiting slide rail 125 and the vertical limiting slide groove 31 are mutually limited and engaged, so that the sliding connection block 12 and the chassis 3 are not separated from each other. Combined with the water inlet blind plug 121 and the water outlet blind plug 122 set at the bottom of the sliding connection block 12, the water inlet blind plug 121 and the water outlet blind plug 122 can be moved downward to communicate with the external cooling device, and the water inlet blind plug 121 and the water outlet blind plug 122 can be moved upward to facilitate the disassembly of the sliding connection block 12 and the maintenance of the plug.

The locking mechanism 13 is arranged at the top of the sliding connection block 12 to fix the sliding connection block 12 on the chassis 3, so that the sliding connection block 12 presses the water inlet blind plug 121 and the water outlet blind plug 122 at the bottom of the sliding connection block 12 without falling off. The locking mechanism 13 facilitates the disassembly of the sliding connection block 12, facilitates the maintenance of the plug, reduces the maintenance cost, and improves the efficiency of maintaining the plug.

[0044] Among them, the locking mechanism 13 includes a rotating shaft 131, a pressure rod 132 and a locking bolt 133. The rotating shaft 131 is located at the top of the limiting slide rail 125.

The limiting protrusion 135 is located above the clamping protrusion 134. The limiting protrusion 135 can abut against the edge of the chassis 3. When the clamping protrusion 134 is embedded in the groove 32, the limiting protrusion 135 abuts against the edge of the chassis 3 to prevent the clamping protrusion 134 from being separated from the groove 32. In this embodiment, by providing the limiting protrusion 135, the clamping protrusion 134 can be effectively fixed in the groove 32 while the pressure rod 132 is clamped against the edge of the upper surface of the chassis 3, so that the sliding connection block 12 can press the water inlet blind plug 121 and the water outlet blind plug 122 at the bottom of the sliding connection block 12 without falling off.
