[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 4 The embodiment of the present invention provides a liquid cooling and heat dissipation leakage prevention device, which can be applied to the liquid cooling device of the server, wherein the liquid cooling and heat dissipation leakage prevention device includes: a leakage collection component 20 and a leakage guide tube 30, the liquid cooling device includes a first plate and a second plate, the bottom edge of the second plate is connected to the edge of the first plate, for example, it can be connected by welding, and a liquid cooling channel for the circulation of coolant is provided between the second plate and the first plate, and the leakage collection component 20 is arranged around the edge where the second plate and the first plate are connected, when the edge where the second plate and the first plate are connected leaks, it can flow into the leakage collection component 20; the leakage guide tube 30 is connected to the leakage collection component 20, and can guide the coolant collected by the leakage collection component 20 to prevent the coolant from flowing to the electronic devices in the server, thereby ensuring the cooling effect of the liquid cooling device and the operation safety of the server. In addition, the leaked coolant can also dissipate heat for the heating element, and under the guiding effect of the leakage guide tube 30, a part of the heat is taken away, thereby achieving the purpose of fully utilizing the coolant.

[0037] In some embodiments, Figure 2As shown, the liquid cooling device includes a liquid cooling plate module 10, which can dissipate heat from the heat generating components of the server, such as the CPU, wherein the liquid cooling plate module 10 includes a cold plate base plate 101 and a cold plate cover plate 102, wherein the cold plate cover plate 102 is covered on the cold plate base plate 101 to form a liquid cooling cavity for the circulation of the cooling liquid. The cold plate cover plate 102 is provided with a liquid inlet joint 103 and a liquid outlet joint 104, and both the liquid inlet joint 103 and the liquid outlet joint 104 are connected to the liquid cooling cavity. A concave cavity may be provided at the bottom of the cold plate cover 102 and / or the top of the cold plate base plate 101. For example, a concave cavity may be provided at the bottom of the cold plate cover 102, and the top surface of the cold plate base plate 101 is a plane. When the two are connected, the concave cavity and the cold plate base plate 101 may constitute a liquid cooling cavity; wherein the cold plate base plate 101 is a first plate member, the cold plate cover 102 is a second plate member, and the edge of the cold plate base plate 101 may be welded to the edge of the cold plate base plate 101. When in use, the cold plate base plate 101 contacts the heating element. When the coolant enters the liquid cooling cavity, the heating element may be cooled by the cold plate base plate 101, and the coolant after heat exchange may flow out through the liquid outlet joint 104. The leakage liquid collection assembly 20 includes a cold plate outer frame 105, which is covered on the cold plate base plate 101, and a liquid inlet joint 103 and a liquid outlet joint 104 extend from the middle of the cold plate outer frame 105 to facilitate the connection of the liquid cooling pipe, wherein the cold plate outer frame 105 can be connected to the cold plate base plate 101 by screws. A first sealing ring 106 is provided between the inner hole periphery of the cold plate outer frame 105 and the cold plate base plate 101, and a second sealing ring 107 is provided between the cold plate outer frame 105 and the cold plate base plate 101 to enclose a leakage liquid collection cavity for collecting leakage liquid. That is, the connection position between the cold plate base plate 101 and the cold plate base plate 101 is surrounded in the leakage liquid collection cavity. When leakage occurs at the mating surface of the cold plate substrate 101 and the cold plate substrate 101, it can flow into the leakage collection chamber and finally be diverted out through the leakage delivery pipe. The coolant in the leakage collection chamber can further cool the cold plate substrate 101, thereby achieving the purpose of sufficient cooling liquid cooling. In addition, the leakage collection component 20 is integrated into the liquid cooling plate module 10, which can effectively reduce the space occupied, and the liquid cooling plate module 10 and the leakage collection component 20 can be pre-assembled as a whole, which can improve the installation efficiency during installation.

[0038] In some embodiments, Figure 3 and Figure 4As shown, the liquid cooling device includes a diverter 40. When multiple liquid cooling plate modules 10 are used to dissipate heat for different heating elements, the diverter 40 can be used to divert the coolant to each liquid cooling plate module 10, wherein the diverter 40 includes a diverter substrate 401 and a diverter cover 402, the diverter cover 402 is covered on the diverter substrate 401, the diverter substrate 401 is a first plate, the diverter cover 402 is a second plate, and a diverter channel 403 is provided on the diverter substrate 401, and the diverter channel 403 is connected to the liquid cooling plate module 10 through a liquid cooling pipe, wherein the diverter cover 402 can be welded by a high-temperature welding process to enhance the compressive strength of the entire structure of the diverter 40. The leakage collection assembly 20 includes an annular channel 404 provided on the diverter substrate 401, the diverter channel 403 is located within the annular range of the annular channel 404, and the annular channel 404 is connected to the leakage guide pipe 30. After the diverter cover 402 is welded to the diverter substrate 401, the diverter channel 403 and the annular channel 404 are in a sealed state except for the interface position. The leakage position of the diverter 40 usually appears at the mating surface of the diverter cover 402 and the diverter substrate 401. For example, due to welding defects, the sealing of the diverter channel 403 may be deteriorated. During operation, the coolant in the diverter channel 403 may leak from the welding defect position. Since a circle of annular channels 404 are provided on the periphery of the diverter channel 403, the leaked liquid will enter the annular channel 404, so the problem of splashing of the leakage of the diverter 40 can be prevented. In addition, by providing an annular channel 404 on the diverter substrate 401 of the diverter 40, compared with providing an additional anti-leakage device, the space occupied can be effectively reduced, and by making full use of the structure on the diverter 40, the use of parts can be effectively reduced, thereby achieving the purpose of reducing costs.

[0041] In addition, the liquid cooling and heat dissipation leakage prevention device also includes a liquid reservoir 60, a liquid inlet main pipe 61 and a liquid return main pipe 62. The liquid reservoir 60 is used to store the coolant, and the two ends of the liquid inlet main pipe 61 and the liquid return main pipe 62 are respectively connected to one of the flow dividers 40 and the liquid reservoir 60, wherein the leakage guide pipe 30 can be connected to the liquid reservoir 60, that is, the leaked coolant can flow back to the liquid reservoir 60, so as to improve the recycling level of the coolant. For example, the liquid reservoir 60 is connected to the liquid inlet of the first diverter 41 through the liquid inlet main pipe 61, and is connected to the liquid return port of the first diverter 41 through the liquid return main pipe 62.

Both the leakage delivery pipe and the leakage guide pipe 30 can be selected as hoses, such as plastic pipes, and the hose can effectively reduce the difficulty of assembly due to its deformable advantage.

[0043] Taking two liquid cooling plate modules 10 and two diverters 40 as an example, two liquid cooling plate leakage collection parts and two diverter 40 leakage collection parts are set accordingly, and the two liquid cooling plate leakage collection parts are respectively recorded as the first liquid cooling plate leakage collection part and the second liquid cooling plate leakage collection part, and the two diverter 40 leakage collection parts are respectively recorded as the first diverter leakage collection part and the second diverter leakage collection part, and four leakage delivery pipelines need to be set accordingly, which are respectively recorded as the first leakage delivery pipeline 81, the second leakage delivery pipeline 82, the third leakage delivery pipeline 83 and the fourth leakage delivery pipeline 84. The delivery pipe 84 is connected as follows: the first diverter leakage collection part is connected to the first liquid cooling plate leakage collection part through the first leakage delivery pipe 81, the first liquid cooling plate leakage collection part is connected to the second diverter leakage collection part through the second leakage delivery pipe 82, the second diverter leakage collection part is connected to the second liquid cooling plate leakage collection part through the third leakage delivery pipe 83, the second liquid cooling plate leakage collection part is connected to the first diverter leakage collection part through the fourth leakage delivery pipe 84, and the first diverter leakage collection part is finally connected to the leakage guide pipe 30.

For the structure in which the server and the liquid cooling heat dissipation leakage prevention device are installed in the chassis, the leaked coolant can be discharged to the outside of the chassis through the leakage guide pipe 30.
