Examples:

referring to fig. 1-6, the present embodiment provides a cooling system, which includes a rack 2 and at least two resource cards 1, wherein the resource cards 1 are detachably matched with the rack 2.

As an alternative specific structure of the resource board 1, it at least includes a PCB board 13 and a cooling board 12, where the cooling board 12 is assembled with the PCB board 13, and in other embodiments, the cooling board 12 may be directly mounted on the PCB board 13. As another example, the resource board card 1 further includes a mounting board 11, and the cooling board 12 and the PCB 13 are both mounted on the mounting board 11, so as to achieve contact or approach of the cooling board 12 to the PCB 13 through the mounting board 11. When the cooling medium is introduced into the cooling plate 12, the cooling plate 12 can cool the PCB 13. The above scheme is one specific matching mode of the PCB 13 and the cooling plate 12.

Wherein the cooling plate 12 is provided with a first joint 121, and the first joint 121 communicates with the cooling plate 12 to feed a cooling medium into the cooling plate 12.

The rack 2 is provided with a cooling medium inlet 221 and a cooling medium outlet 222, the number of the cooling medium outlets 222 is at least two, and the number of the cooling medium outlets 222 is not less than that of the resource cards 1, so that all the resource cards 1 on the rack 2 can obtain cooling liquid supply. All the cooling medium outlets 222 are connected in parallel to the cooling medium inlet 221 such that the cooling medium inlet 221 communicates with each of the cooling medium outlets 222. Wherein a second joint 2221 is provided at each cooling medium outlet 222.

The rack 2 is provided with an electric coupling joint 213, the resource board card 1 is assembled in place on the rack 2 and comprises two layers, the first layer is the position of the PCB 13 on the rack 2 to realize electric connection with the electric coupling joint 213, the second layer is the position of the cooling plate 12 on the rack 2 to enable the first joint 121 to be coupled to the corresponding second joint 2221, and the cooling medium inlet 221 can be used for introducing cooling medium into the cooling plate 12.

In the prior art, the assembly of the PCB 13 on the frame 2 and the coupling of the first connector 121 and the second connector 2221 are performed in two steps, which results in lower assembly efficiency and complicated steps of the resource board 1.

For this reason, the frame 2 in this embodiment is provided with the guiding structure 212, the guiding structure 212 is used for guiding the installation process of the cooling board 12 and the PCB 13 on the frame 2, so that in the process of assembling the PCB 13 onto the frame 2, the alignment of the first connector 121 and the second connector 2221 is synchronously realized, thereby realizing the one-step assembly of the resource board 1 on the frame 2, simplifying the installation steps of the resource board 1, improving the assembly efficiency, and along with the increase of the assembly quantity of the resource board 1, the improvement of the installation efficiency is more obvious.

In order to protect the resource board card 1, the rack 2 of this embodiment includes a box 21, the box 21 is substantially rectangular, a disassembly and assembly opening 211 is formed on an outer wall of a front side of the box 21, and the resource board card 1 can enter and exit the box 21 through the disassembly and assembly opening 211. When a part or all of the resource board 1 is located in the housing 21, protection of the housing 21 is obtained.

Wherein the case 21 is formed by splicing a plurality of steel plates, and the edges of the steel plates are provided with a plurality of second mounting holes 216 to improve the connection accuracy between the steel plates.

In order to facilitate maintenance in case of leakage between the cooling medium inlet 221 and the cooling medium outlet 222, the frame 2 further comprises a split block 22 mounted on the outer wall of the case 21, and both the cooling medium inlet 221 and the cooling medium outlet 222 are located on the split block 22. It is further preferred that the diverter block 22 be removably coupled to the outer wall of the housing 21 by a connector block 23 to facilitate removal of the diverter block 22 from the housing 21 for servicing.

Wherein, a plurality of first mounting holes 215 are arranged on the box body 21, and the first mounting holes 215 promote the mounting precision of the connecting block 23, thereby indirectly promoting the mounting precision of the split-flow block 22 and facilitating the alignment of the first joint 121 and the second joint 2221.

The guide structure 212 of this embodiment includes guide rails 2122, and the number of guide rails 2122 is identical to the number of cooling medium outlets 222, so that each guide rail 2122 cooperates with the corresponding cooling medium outlet 222 in the installation process of a single resource board 1. The guide rail 2122 is located at the inner wall of the case 21 and extends in the front-rear direction of the case 21 so as to cooperate with the edge of the mounting board 11 to guide the main structure of the resource board 1 into the case 21.

The edge of the mounting plate 11 is provided with a groove 111, the groove 111 being in sliding engagement with the rail 2122, thereby restricting the mounting direction of the resource board 1 on the housing 21 and aligning the first connector 121 and the second connector 2221. When the resource board 1 needs to be removed from the housing 21, the guide rail 2122 has a restriction effect on the mounting plate 11, so that the acting force between the first connector 121 and the second connector 2221 can be along the axial directions of the two as much as possible, thereby reducing the damage of the first connector 121 and the second connector 2221.

Preferably, the guide rail 2122 extends to the edge of the mounting opening 211, so that the guide rail 2122 is immediately guided when the mounting plate 11 reaches the mounting opening 211.

The guide rail 2122 may be formed by grooving the inner wall of the case 21, or may be formed by providing two parallel guide bars on the inner wall of the case 21. The specific implementation structure and manner of the guide rail 2122 are related art, and this embodiment is not described in detail.

Since the cooling medium outlet 222 is located outside the housing 21, the corresponding first connector 121 should also be located outside the housing 21, and accordingly, a portion of the resource board 1 is located inside the housing 21, and another portion of the resource board 1 is located outside the housing 21. The part of the resource board 1 located outside the case 21 is in the structure of a lug 122, so that the first connector 121 is also located on the lug 122.

Based on this, the guiding structure 212 of this embodiment includes an avoidance notch 2121, the avoidance notch 2121 is located at the edge of the dismounting opening 211, the mounting board 11 enters the process of the box 21, the box 21 avoids the lug 122 through the avoidance notch 2121, and finally the coupling between the first joint 121 and the second joint 2221 is realized.

The mounting plate 11 is guided by the engagement of the grooves 111 with the guide rails 2122 during the mounting into the case 21, but the lugs 122 are generally in a floating state during this process, and the lugs 122 may cause poor alignment between the first and second joints 121 and 2221 due to local deformation, and the closer the lugs 122 are to the cooling medium outlet 222, the greater the amount of misalignment of the first and second joints 121 and 2221 in the radial direction.

Based on the above, the guide structure 212 of the present embodiment includes the guide posts 2123, the guide posts 2123 are mounted on the split block 22, and the number of the guide posts 2123 is the same as the number of the second joints 2221. The lugs 122 are correspondingly provided with guide holes 1221 which mate with the guide posts 2123. When the lug 122 just reaches the avoidance notch 2121, the radial dislocation amount between the first joint 121 and the second joint 2221 is not large, and the lug 122 enters the guide hole 1221 through the guide post 2123, so that the movement guide of the lug 122 in the avoidance notch 2121 is realized, the deformation of the lug 122 is restrained, and the first joint 121 and the second joint 2221 can be successfully butt-coupled finally.

In this embodiment, the length of the guide post 2123 is limited, and the process of entering the guide hole 1221 by the guide post 2123 occurs when the mounting plate 11 reaches the rear position of the housing 21, so that the guide post 2123 cannot perform the guiding function when the mounting plate 11 reaches the mounting and dismounting port 211.

In some other embodiments, if the guide post 2123 is required to guide just as the mounting plate 11 reaches the mounting and dismounting port 211, the guide post 2123 is required to be long enough to synchronize with the entry into the guide hole 1221. On the other hand, however, the condition that the guide post 2123 can effectively cooperate with the guide hole 1221 is that the guide post 2123 cannot be too long, otherwise the guide post 2123 may be effectively deformed or broken, and for this reason, the guide post 2123 of the present embodiment cannot replace the guiding action of the guide rail 2122.

In some embodiments, the relief notch 2121 may provide a preliminary guiding function for the lug 122 that has just entered, so that the guide post 2123 may enter the guide hole 1221, and then the guide post 2123 may be mated with the guide hole 1221, so that the first joint 121 and the second joint 2221 are finally aligned, that is, two-step alignment between the first joint 121 and the second joint 2221 is achieved during the process of entering the mounting plate 11 into the box 21, and the effect of coupling docking is more easily achieved by the first joint 121 and the second joint 2221 without adding an additional mounting step.

The resource board card 1 of the present embodiment further includes an electrical connector 14, and the electrical connector 14 is disposed on the mounting board 11 and electrically connected to the PCB 13. Correspondingly, the electrical coupling 213 is located in the housing 21. In which the electric coupling joint 213 and the attachment/detachment port 211 are disposed opposite to each other, that is, opposite to each other in the axial direction of the guide rail 2122, the electric coupling joint 213 and the electric connector 14 can be aligned when the mounting plate 11 is mounted in the housing 21 along the axial direction of the guide rail 2122, so that the coupling operation of the first joint 121 and the second joint 2221 is completed in synchronization with the coupling operation of the electric connector 14 and the electric coupling joint 213.

More specifically, the cooling system of the present embodiment further includes a back plate 4 and a power supply plate 5. The rear side wall of the case 21 is open, and the electric coupling joint 213 and the power board 5 are both mounted on the back plate 4 to achieve electric connection, and the back plate 4 is mounted on the rear side wall of the case 21, so that the electric coupling joint 213 is located in the case 21, and the electric connector 14 can be electrically connected to the power board 5 to obtain power after being coupled with the electric coupling joint 213.

In order to facilitate the mounting and dismounting process of the mounting plate 11, the resource board card 1 further comprises a handle 15, and the handle 15 is mounted on the mounting plate 11. In which the handle 15 and the electrical connector 14 are opposed in the axial direction of the guide rail 2122, the handle 15 can be disposed toward the outside of the attaching/detaching port 211 for easy gripping after the mounting plate 11 is fitted in place on the case 21.

After the resource board 1 is assembled in place on the frame 2, in order to ensure connection stability, the cooling system further comprises a locking member 3, wherein the locking member 3 can be mounted on the resource board 1, and also can be mounted at the edge of the dismounting opening 211 as in the embodiment, specifically, the edge of the dismounting opening 211 is provided with a lock hole 214, and the locking member 3 is movably arranged at the lock hole 214. Correspondingly, the resource board card 1 of the embodiment is provided with a locking groove 16, the locking piece 3 is matched with the locking groove 16, and the resource board card 1 is locked on the rack 2 through the locking piece 3.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
