The module is equipped with a connector for external communication and a liquid connector for liquid circulation, and before formal delivery, multi-module joint debugging and vibration impact test are required.

[0035] The utility model embodiment discloses a vibration test fixture for penetrating liquid cooling module, the fixture effectively solves the problem of large power consumption, no debugging and heat dissipation tooling of penetrating liquid cooling module, and can meet the requirements of vibration and impact test. The fixture is composed of a clamp body 1, a flow divider assembly 2 and a bottom plate module, and has the advantages of simple structure, convenient disassembly and assembly, multiple reinforcement, easy maintenance and the like.

[0036] The clamp body 1 is the main part of the test clamp, has no liquid passing function, and has no electronic components thereon, mainly bears the force and connects the shunt assembly 2, the bottom plate module and the to-be-tested penetrating liquid cooling module to the vibration test table, and the device module guide installation groove is located on the left and right sides of the clamp body 1, and the liquid cooling module is horizontally inserted during assembly. The clamp body 1 is composed of a clamp lower side plate 15, a clamp left side plate 13, a clamp right side plate 14, a clamp upper side plate 11, a clamp rear side plate 12, a reinforcing rib 16, a reinforcing rib 17, a detachable stop block 18 and a detachable stop block 19. The clamp lower side plate 15 is the base of the clamp, and has a through hole and a counterbore hole for connecting with the vibration table, and meanwhile, the clamp left side plate 13, the clamp right side plate 14, the clamp upper side plate 11, the clamp rear side plate 12, the reinforcing rib, the shunt assembly 2 and other components are directly or indirectly connected and fixed according to certain rules. The detachable stop block has two types, which are respectively installed on the clamp left side plate 13 and the clamp right side plate 14, and can be selected from appropriate materials such as aluminum alloy or stainless steel according to the module insertion requirement. The detachable stop block has a U-shaped cross section, and the two protruding parts assist the pulling and pushing of the module, and only need to be slightly adjusted in length, width and height to adapt to different types of pullers.

[0037] The shunt assembly 2 is the core part of the clamp, which is composed of a shunt 21, an O-shaped sealing ring 22, a pressing block 23, a module plug-in fluid connector 24 and a liquid cooling source plug-in connector. The shunt 21 is designed with deep holes, and an annular groove for installing the sealing ring is designed at the top. The pressing block 23 is connected with the shunt 21 through threads, and after being fastened, the O-shaped sealing ring 22 is deformed to realize fluid sealing. The liquid inlet and the liquid outlet of the shunt 21 are coaxial, which is beneficial to reduce the flow resistance. The liquid cooling source plug-in connector has a sealing ring, which can ensure the sealing of the joint between the liquid cooling source and the shunt 21, so that only the thread holes for installing the liquid cooling source plug-in connector are left at the left and right ends of the shunt 21, without other sealing measures. The top and bottom of the shunt assembly 2 are screw-connected with the clamp upper side plate 11 and the clamp lower side plate 15 respectively, and it is surrounded in the frame composed of the clamp rear side plate 12, the clamp lower side plate 15, the clamp left side plate 13, the clamp right side plate 14 and the clamp upper side plate 11.

This not only helps signal wiring of the functional module connectors on the bottom plate module, but also reduces signal interference to the functional module. Moreover, arrangement on the bottom layer helps conduction heat dissipation of the power module and overall structural stability. The bottom plate module is connected and fixed with the clamp rear side plate 12 through screws, and the bottom plate module can be used for power supply of modules in the clamp, and meanwhile realizes interconnection and intercommunication between modules, and the number of the connectors distributed thereon depends on the design height of the clamp. In order to ensure stable installation of the module when vibrating, the number is as small as possible.

[0039] The vibration test clamp in the utility model adopts horizontal type insertion design. After the liquid cooling module is inserted into the guide groove of the clamp, the cooling guide ribs of the liquid cooling module and the locking strips mounted thereon are locked and extruded in the guide groove through a tool, so that the module installation and heat dissipation are realized. The clamp rear side plate 12 is connected with the clamp upper side plate 11 and the clamp lower side plate 15 at the top and the bottom respectively, and meanwhile, the clamp rear side plate 12 has reinforcing ears on the left and right sides, which are connected with the clamp left side plate 13 and the clamp right side plate 14, so as to ensure the stability of the clamp frame, and meanwhile, a plurality of threaded holes are uniformly distributed on the reinforcing ears for cooperation and installation with the bottom plate module.

The reinforcing ribs are symmetrically distributed on the left and right sides of the clamp.

[0040] The device has multiple state modes such as normal temperature debugging, liquid passing debugging and normal temperature vibration, liquid passing vibration and the like. The normal temperature debugging means that the device does not install the liquid distributor 21 or the module cooperates with the liquid distributor 21 but the outside is not connected with the cooling liquid. The liquid passing debugging means that the liquid connectors of the inlet and outlet of the liquid distributor 21 are connected with the liquid cooling source, and the debugging is performed under the condition that the liquid cooling source stably supplies liquid. The detachable stopper includes detachable stopper one 18 and detachable stopper two 19. When the module insertion force is large or the vibration power spectral density is large, the material of the stopper can be selected from stainless steel to meet or ensure the smooth module insertion and vibration safety. Under normal circumstances, aluminum alloy can meet the requirements. The detachable stopper is in U shape, two protruding parts assist the module pulling and pushing respectively, and different models of pullers can be adapted through design modification. The detachable stopper is designed with a counterbore, and a locking screw is installed in the counterbore, which does not affect the module insertion and ensures the fastening connection between the stopper and the side plate.
