[0037] As shown, Figure 6 The main shaft 1 is designed with a main shaft flow channel 103, the cooling liquid can enter the main shaft and flow out from the outlet hole 102 after one circle, and the plug 104 is used to block the process hole in the processing process. The diameter of the main shaft flow channel 103 is not less than 0.5mm, the edge of the main shaft flow channel 103 is not less than 0.8mm from each edge of the main shaft 1, and is not less than 0.5mm from the edge of other mounting holes and through holes of the main shaft 1. The inlet hole 101 and the outlet hole 102 are determined according to the relative installation position of the module, the inlet hole 101 is close to the inside of the electronic equipment module, and the outlet hole 102 is close to the outside of the electronic equipment module, so that the cold end is close to the heat source, and the hot end is away from the heat source.

[0038] As shown, Figure 7 The liquid cooling connector 2 is designed with a liquid outlet cavity 201 and a liquid return cavity 202, and the two cavities are independent and not communicated. As shown, Figure 5 And Figure 8 The liquid cooling connector 2 is welded to the main shaft 1, so that the inlet hole 101 of the main shaft is connected with the liquid outlet cavity 201 of the liquid cooling connector, and the outlet hole 102 of the main shaft is connected with the liquid return cavity 202 of the liquid cooling connector.

[0039] The limiting block 3 is designed with a mounting hole of the limiting pin 4, the limiting pin 4 is inserted into the hole of the limiting block 3, and the limiting pin 4 is used in cooperation to realize the limiting of other moving blocks.

[0040] The locking assembly composed of the upper sliding block 5, the lower sliding block 6, the push block 7, the pad block 8 and the screw rod 9 is a commonly used locking device.

[0041] When the electronic equipment works, the components generate heat, the heat is conducted to the conduction cold plate through the heat conduction interface material, and then is transmitted to the flowing cooling liquid in the device through the liquid cooling locking device, the heat is taken away by the efficient convection heat exchange in the liquid cooling locking device, and the heat dissipation of the electronic equipment is realized.

[0042] When the liquid cooling locking device of the airborne electronic equipment of the utility model is used, the following steps are included:

[0043] The first step is the assembly of the liquid cooling locking device.
