According to an embodiment of the application, a liquid cooling box for accommodating electronic equipment is provided. The electronic equipment needs to receive the circulation heat dissipation of the cooling liquid in the liquid cooling box body, and meanwhile, needs to realize the functions of the electronic equipment as a processor and a server through line connection. The cable punches and wears out in box structure and can reduce the leakproofness of box, and then lures the coolant liquid gasification to volatilize, spills from the cavity department of top. The liquid cooling box body improves the connection mode of electronic devices such as electronic equipment and an external power supply module, and accordingly the tightness of the liquid cooling box body is improved.

As shown in fig. 1 to 3, the liquid cooling box body is provided with an electric connection port 11, and the electric connection port 11 is used for providing a space for docking the power supply module 2 with the electronic equipment inside the box body. The side wall 1 of the box body is also provided with a fixing hole 12, the fixing hole 12 is arranged around the electric connection port 11 and is used for being matched with the power supply module 2, so that the power supply module 2 can be fixedly buckled at the electric connection port 11 through the fixing hole 12.

The power supply module 2 is used for performing functions such as power conversion and filtering for the electronic equipment, and realizing stable power supply of an external power supply to the internal electronic equipment. The power supply module 2 is provided with a plug port 21, a cable with a plug can be plugged on the plug port 21, and then the other end of the cable can be plugged on electronic equipment in the liquid cooling box body, so that circuit connection is realized. As shown in fig. 2 and 3, the power supply module 2 is integrally disposed on the outer side of the side wall 1 of the box, and the side of the power supply module 2 with the plugging port 21 is fastened to the electric connection port 11 from the outer side of the side wall 1 of the box. The plugging port 21 faces to the inside of the box body through the electric connection port 11, so that the cable can be conveniently plugged on the plugging port 21 of the power supply module 2 in the liquid cooling box body, and electric connection is realized. By means of the power supply module 2 being fastened to the electric connection port 11, the sealing effect at the electric connection port 11 can be enhanced. The power supply module 2 is formed with a fitting hole 22, and the position of the fitting hole 22 corresponds to the position of the fixing hole 12, that is, the fitting hole 22 surrounds the electric connection port 11.

In particular, the power supply module 2 is connected in a latching manner by means of a rivet nut 3 and a threaded connection. The rivet nut 3 has a hollow column structure, and threads are formed on the inner surface of the rivet nut. The threaded connection may be screwed into an internal thread of the rivet nut 3, for example, to form a threaded connection. Under the condition that the threaded connecting piece is screwed down, the cylindrical riveting nut 3 can be deformed under the riveting action, and under the riveting action of the threaded connecting piece, the middle section of the riveting nut 3 can be compressed and expanded to deform, so that the cylindrical riveting nut is clamped on the inner side and the outer side of the side wall 1 of the box body, and good fixed connection action and sealing action are realized.

In the technical solution of the present application, the rivet nut 3 passes through the fixing hole 12, and a part of the rivet nut is located at the outer side of the side wall 1 of the box body, and a part of the rivet nut extends to the inner side of the side wall. The threaded connecting piece is inserted into the assembly hole 22 of the power supply module 2 and the threaded hole of the riveting nut 3, and the threaded connecting piece locks the fixed module on the side wall 1 of the box body through threaded fixation and covers the electric connection port 11 and the riveting nut 3. The rivet nut 3 is subjected to the locking action of the threads of the threaded connecting piece to form rivet deformation, the deformed and expanded part of the rivet nut is tightly supported in the fixing hole 12, one section of the rivet nut 3 outside the box side wall 1 is pressed on the outer surface of the box side wall 1, and one section of the rivet nut positioned inside the box side wall 1 is pressed on the inner surface of the box side wall 1.

With this fitting relationship, the fixing hole 12 can be closed by the rivet nut 3 first, reducing the risk of air leakage at the fixing hole 12. Second, the threaded connection piece locks and laminates power supply module 2 on the box lateral wall 1, so as to cover electric connector 11, realize laminating and seal, reduce the gas leakage risk of electric connector 11 department. Through this kind of connected mode, the electronic equipment in the cooling box need not to pass box lateral wall 1 to the box lateral wall 1 outside through the cable and carries out electric connection, effectively reduces trompil, the gap on box lateral wall 1, improves the gas tightness, reduces the volatile risk of inside coolant liquid.

Further, when the single electronic equipment needs to be powered off for maintenance, the power supply module 2 is arranged on the liquid cooling box body, so that the cable joints between the electronic equipment and the power supply module 2 are not required to be removed, and the risks of joint error unplugging and error plugging are reduced. In addition, the length of the cable is shortened by the design, so that the cable is beneficial to wiring in the liquid cooling box body and space occupation of the cable is reduced. In practical application, after a single power line is damaged, normal work of other IT equipment can be not influenced, and independent replacement can be performed instead of splitting replacement after the whole of a plurality of integrated cables is detached. The operation efficiency of the later operation and maintenance personnel is greatly improved.

Alternatively, the rivet nut 3 may employ a polygonal rivet nut 3. For example, the rivet nut 3 may employ a pentagonal rivet nut 3 or a hexagonal rivet nut 3. The polygonal outer surface of the cylindrical riveting nut 3 can reduce the possibility of axial rotation of the riveting nut 3, thereby improving the reliability of fixed connection. Alternatively, the fixing hole 12 may be a polygonal hole matching the shape of the outer surface of the rivet nut 3, which is matched with the rivet nut 3. Like this, rivet nut 3 peg graft in fixed orifices 12 is difficult for taking place to rotate, in the in-process with threaded connection spare rotation locking rivet nut 3, rivet nut 3 is difficult for taking place relative rotation because between rotatory effect and the fixed orifices 12, and then avoid appearing threaded connection and be difficult to lock power module 2 on box lateral wall 1.

Further, the outer surface of the rivet nut 3 is matched with the shape of the fixing hole 12, and after the rivet nut 3 is deformed by pulling rivet by the threaded connecting piece, the rivet nut 3 can be better tightly supported on the fixing hole 12 to form sealing fit. Particularly, when certain power supply modules 2 need to be maintained and replaced, if the threaded connection piece needs to be unscrewed, the polygonal riveting nut 3 and the fixing hole 12 can be better detached, and the situation that the riveting nut 3 rotates along with the threaded connection piece and is damaged is difficult to occur. The disassembly efficiency is improved.

Optionally, a water return hole is formed in the side wall 1 of the box body. Along the height direction of the liquid cooling box body, the water return hole is positioned at a relatively lower position relative to the electric connection port 11. Correspondingly, the power supply module 2 is provided with an inclined plate at a position corresponding to the water return hole. From the outside direction of box lateral wall 1 to the inboard direction, the hang plate downward sloping, the lower extreme and the return water hole butt joint of hang plate. The inclined plate may be formed of a lower case of the power supply unit as long as it is inclined inward and downward to some extent. The cooling in the liquid-cooled tank has a natural gasification phenomenon, and some of the cooling liquid gas which is difficult to avoid is diffused into the power supply module 2 due to the electrical connection port 11. The temperature of the power supply module 2 is relatively low and the cooling liquid may condense into droplets. In this case, the inclined plate can guide the condensed coolant to flow back to the position of the water return hole, and thus drip back to the power supply module 2. The inclined plate of the power supply module 2 and the water return hole on the side wall 1 of the box body can be matched to further reduce the loss of cooling liquid.

The threaded connecting piece is screwed into the box body from one side of the opening to lock the power supply module 2 and rivet the riveting nut 3, and the closed end of the riveting nut 3 is inserted into the inner side of the box body side wall 1 through the fixing hole 12. The closed rivet nut 3 can reduce the possibility of volatilization and dissipation of the cooling liquid in the box body and improve the tightness of the fixing structure.

Optionally, the rivet nut 3 may be subjected to a glue coating treatment, so as to increase the tightness between the rivet nut 3 and the fixing hole 12, and improve the overall sealing performance of the box body. For example, an adhesive or soft silica gel may be applied to the outer surface of the rivet nut 3. The coating material can on the one hand play a role in sealing gaps and on the other hand play a role in conducting heat to a certain extent, so that the heat dissipation capacity of the area where the power supply module 2 is located is improved.

Optionally, as shown in fig. 5, the liquid cooling box may further include a gasket 4, where the gasket 4 is used to seal the electrical connection port 11. The electric connection port 11 is used for requiring butt joint of the plug-in port 21, and is the part of the whole liquid cooling box body where gas leakage is most easy to occur. The technical scheme uses the mode that the power supply module 2 is integrally buckled on the electric connection port 11 to strengthen the sealing effect. On this basis, a gasket 4 may also be provided between the power module 2 and the case side wall 1, the power module 2 and the case side wall 1 sandwiching the gasket 4. At a position corresponding to the electric connection port 11, the gasket 4 does not form a shield to the electric connection port 11, and is located around the electric connection port 11. The gasket 4 can form an effective seal against the gap between the power supply module 2 and the tank side wall 1, and under the locking action of the threaded connection, the power supply module 2 can form backlog against the gasket 4 and the tank side wall 1, thereby eliminating the gap.

Optionally, the sealing pad 4 may be provided with an avoidance hole 41, and the avoidance hole 41 is used for avoiding the rivet nut 3. During assembly, the rivet nut 3 passes through the relief hole 41. Under the condition that the threaded connecting piece is locked in the rivet nut 3 to form rivet pulling, the expanded rivet nut 3 can just tightly support the avoiding hole 41, so that a better sealing fit relationship is formed with the sealing gasket 4, the air tightness is enhanced, and the gasification leakage of cooling liquid is prevented. The various optional means of improving the sealing properties of the present application may be used in combination, thereby significantly improving the reliability of the sealing at the electrical connection port 11. Although the whole opening of the electric connection port 11 is larger, the tightness can be effectively improved by utilizing the snap fit sealing measure of the power supply module 2, and the tightness is ensured while the convenient electric connection relation is realized.

Alternatively, the gasket 4 may be adhesively secured to the case side wall 1. The gasket 4 is pre-attached to the side wall 1 of the case at a position corresponding to the electrical connection port 11 by gluing or attaching an adhesive layer. The adhesive layer can improve sealed effect on the one hand, on the other hand can provide stability for the assembly, simplifies assembly process. Fixing the sealing gasket 4 on the side wall 1 of the box body through the bonding layer can improve the positioning accuracy of the sealing gasket 4 and the electric connection port 11, and is also convenient for positioning the power supply module 2 on the sealing gasket 4.
