The invention provides a sealing method which is easy to implement, and a sealing structure which has simple structure and good sealing performance.
Further as shown in the figure, the upper cover 1 and the shell 3 are in sealing connection through a sealing ring 2. Specifically, one of the upper cover 1 and the housing 3 is provided with an annular groove, and the other is provided with an annular flange matching the shape of the annular groove, wherein the seal ring 2 is provided in the annular groove.
In a preferred embodiment of the invention, the shape of the sealing ring 2 matches the shape of the annular groove, and the sealing ring 2 has an H-shaped cross section. It will of course be understood that the shape of the sealing ring 2 is only illustrative and the invention is not limited thereto. In an alternative embodiment, the inner edge of the annular groove and the outer edge of the annular flange are each formed with a chamfered edge.
With continued reference to the figures, in one embodiment of the invention the inlet valve 7 comprises an inlet fitting 7.3, a fixing nut 7.2 rotatably mounted on the inlet fitting 7.3, and a sealing ring 7.1. Specifically, the inlet valve 7 is in sealing connection with the housing 3 via a fixing nut 7.2 and a sealing ring 7.1.
Similarly to the inlet valve 7, the outlet valve 5 comprises an outlet fitting 5.2 and a sealing ring 5.1.

Furthermore, the side wall of the housing 3 is formed with a mounting hole from which the exchange module 8 protrudes to the outside of the housing 3, wherein a sealant is coated between the mounting hole and the exchange module 8.
As can be seen from the schematic diagrams of the present invention shown in fig. 1 to 9, to ensure the sealability of the inside of the blade, three main aspects are required: first, the fixing and sealing between the upper cover 1 and the housing 3; secondly, the liquid inlet and outlet connector used by the cold liquid circulation system is connected and sealed with the blade shell 3; thirdly, good electrical conduction between the hvth plate 4 and the exchange module 8 needs to be ensured and the sealing structure should not damage and interfere with the circuit board.
As shown in fig. 1, the upper cover 1 and the housing 3 are sealed by a seal ring 2. As shown in fig. 5, an annular groove is provided around the upper end face of the housing 3. As shown in fig. 4, an annular convex groove is provided around the lower end surface of the upper cover 1. The shell 3 and the upper cover 1 are matched with an annular flange through an annular groove, the sealing ring 2 is arranged in the annular groove, and the annular flange is embedded in the annular groove and presses the sealing ring.
As shown in fig. 6, the shape of the sealing ring 2 is the same as the shape of the groove of the housing 3, and can be completely embedded in the groove. As shown in fig. 7, the cross section of the sealing ring 2 is H-shaped, and the annular flange of the upper cover 1 presses the sealing ring 2 when being embedded into the groove of the housing 3. The structure plays a role in locating the joint, and effectively solves the problem that the sealing effect is poor due to dislocation of the joint when the upper cover 1 is covered on the shell 3. Due to the H-shaped design, the annular flange of the upper cover 1 is downwards pressed, and meanwhile, the annular flange is simultaneously and inwards wrapped by the sealing ring 2, so that the extrusion force born by the sealing ring 2 is increased, the contact area between the sealing ring 2 and the upper cover 1 is increased, and the air tightness of the blade is ensured.
Further, the provision of the annular groove and the annular flange is provided in two different ways: in the first embodiment, as shown in fig. 4 and 5, an annular groove is provided on the housing 3, and an annular flange is provided on the upper cover 1. In the second embodiment, an annular groove is formed in the upper cover 1, and an annular flange is formed in the housing 3. The structural distribution of the above embodiments may be arbitrarily set according to specific structural requirements.
Further, both the annular groove and the annular flange are provided with chamfered edges, which allow the annular flange to be more easily pressed into the annular groove.
Further, in order to avoid the phenomenon of leakage of liquid caused by insufficient pressing force on the opposite side due to the fact that one side is tightened first during installation. Preferably, a uniform preload is applied to the upper cover prior to installation of the upper cover.
As shown in fig. 1, the connection and sealing of the inlet and outlet liquid joint and the blade housing 3 for the cooling liquid circulation system is critical in order to ensure the tightness of the blade interior. As shown in fig. 8, the inlet valve 7 is fixed with the housing 3 by means of a fixing nut 7.2. The fixed nut 7.2 and the liquid inlet joint 7.3 are rotatable, and a sealing ring is sleeved between the fixed nut and the liquid inlet joint. The bottom end of the liquid inlet valve is provided with a sealing ring 7.1, the sealing ring 7.1 is matched with a groove arranged in a corresponding hole position of the shell, and when the liquid inlet valve 7 is pushed inwards by a fixing nut 7.2, the sealing ring 7.1 is extruded with the groove.
The sealing of the pressure regulating valve 6 and the outlet valve 5 as shown in fig. 9 is also accomplished by pressing the sealing ring against the groove inside the housing.
As shown in fig. 2 and 3, the circuit board is arranged inside the blade and needs to extend to the outer end of the blade, and the exchange connector and the power connector fixed on the circuit board are connected with the back plate of the chassis to supply power to the blade and realize data exchange between the blades. The exchange module 8 and the hvdc plate 4 are one plate but outside and inside the blade, respectively. In order to effectively seal the square port extending from the plate as shown in fig. 2, the square port is fixed at the corresponding position of the cutter housing 3 by screws and holes distributed on the power supply direct current plate 4, and the exchange module 8 extends out of the outer end of the cutter blade from the square hole. After fixing, specific glue mixed in a certain proportion is smeared at the square hole, standing is carried out for half a day after the fixing, the hole is thoroughly sealed after the glue is completely dried, and the power supply direct current plate 4, the exchange module 8 and the blade shell 3 are fixedly connected into a whole. The square holes are sealed by the specific glue, so that the square holes can play a role in sealing, the exchange module 8 can be fixed, the glue has certain elasticity after being dried, no bubbles exist in the glue, the glue does not have conductivity, and the material stability is extremely high. The blade treated by the method can be arbitrarily inserted and pulled out without damaging the tightness of the square hole.
In summary, compared with the prior art, the invention has the following advantages: the device takes a full-immersion liquid cooling heat dissipation mode as a background, adopts the full-immersion liquid cooling heat dissipation mode, needs a sealed cavity inside the blade, ensures the tightness inside the blade, can effectively avoid the adverse effect of external severe environmental conditions on the operation and heat dissipation of the server, and is favorable for popularization of the server in severe environments; the difference between the blade server and other box structures is fully considered, and the sealing structure design adopts different schemes at different positions, so that the structure is more reliable and safer, and the corrosion resistance of the material is stronger.
