When the liquid leakage occurs between the connecting portions 410 of the two pipe fittings 400, the liquid can flow into the liquid collecting groove 110 and flow into the flow guide pipe 200 through the through hole 120, and finally the liquid is guided to the safe area by the flow guide pipe 200, so as to avoid the liquid from spreading to the server at will and further avoid the short circuit phenomenon of the server, thereby improving the safety of the server cabinet.

[0060] As shown, Figure 5 The pipe fitting 400 further comprises a pipe body 420, and the connecting portion 410 of the pipe fitting 400 is arranged at one end of the pipe body 420. The pipe bodies 420 of the two pipe fittings 400 are connected through the connecting portion 410. In an embodiment, the two pipe fittings 400 are butt-jointed along the axial direction of the pipe fitting 400, that is, the axes of the two pipe fittings 400 coincide. In other embodiments, the two pipe fittings 400 can also be connected at an angle, for example, the included angle between the two pipe fittings 400 is between 20° and 170°, which is not particularly limited in the present application.

[0061] In an embodiment, the connecting portion 410 of the pipe fitting 400 can be a pipe joint, but is not limited thereto.

[0062] Please continue to refer to Figure 5 The liquid collecting sleeve 100 comprises a first sub-cover 130 and a second sub-cover 140, the first sub-cover 130 and the second sub-cover 140 are buckled to each other, and the connecting portions 410 of the two pipe fittings 400 are covered between the first sub-cover 130 and the second sub-cover 140, and the liquid collecting groove 110 and the through hole 120 are arranged on the second sub-cover 140. Among them, the second sub-cover 140 has the liquid collecting groove 110.

[0063] In the embodiment of the present application, the liquid collecting sleeve 100 is designed as a split cover structure. When assembling the pipe fittings 400 and the liquid collecting sleeve 100, the two pipe fittings 400 can be assembled first, and then the first split cover 130 and the second split cover 140 are buckled. This is more convenient to operate.

[0064] Of course, in other embodiments, the liquid collecting sleeve 100 can also be a ring structure. When assembling the pipe fittings 400 and the liquid collecting sleeve 100, the liquid collecting sleeve 100 can be sleeved on the outer periphery of one of the pipe fittings 400 first, and then the two pipe fittings 400 are connected, and finally the liquid collecting sleeve 100 is moved to be sleeved on the outer periphery of the connecting portion 410 of the two pipe fittings 400.

[0065] In an embodiment, the liquid collecting sleeve 100 further comprises at least one fastener 150, which fastens and connects the first split cover 130 and the second split cover 140. By providing the fastener 150, the connection strength between the first split cover 130 and the second split cover 140 can be improved.

[0066] The fastener 150 can be a clamp, a bolt, etc., which is not particularly limited in the present application.

[0067] As shown in Figure 5 and Figure 6 The liquid collecting groove 110 has a groove side wall 111 and a groove bottom wall 112 connected to each other, and the through hole 120 is formed on the groove bottom wall 112. The inner wall surface of the groove bottom wall 112 has a slope surface 1121, which has an uphill end 1121a and a downhill end 1121b. The uphill end 1121a is connected to the groove side wall 111, and the through hole 120 is located on the side of the downhill end 1121b of the slope surface 1121. The uphill end 1121a refers to the starting position of the slope, which is usually the higher end of the slope; and the downhill end 1121b refers to the end position of the slope, which is usually the lower end of the slope.

[0068] In the embodiment of the present application, the groove bottom wall 112 of the liquid collecting groove 110 is provided with the slope surface 1121, and the through hole 120 is arranged on the side of the downhill end 1121b of the slope surface 1121. In this way, when the liquid drops into the liquid collecting groove 110, it can flow along the slope surface 1121 and finally flow to the flow guide pipe 200 through the through hole 120, so as to avoid the liquid remaining in the liquid collecting groove 110.

[0069] As shown in Figure 6As shown in the figures, the groove sidewall 111 comprises two sub-sidewalls 1111 oppositely arranged along the axial direction of the pipe fitting 400; the inclined surface 1121 has two sub-inclined surfaces 1121c oppositely arranged along the axial direction of the pipe fitting 400; the uphill ends 1121a of the two sub-inclined surfaces 1121c are respectively connected to the two sub-sidewalls 1111, and the two sub-inclined surfaces 1121c respectively extend from the respective corresponding sub-sidewall 1111 towards each other, and the through hole 120 is located between the downhill ends 1121b of the two sub-inclined surfaces 1121c.

[0070] In the embodiment of the present application, the through hole 120 is located between the two sub-inclined surfaces 1121c, and when the connection part 410 between the two pipe fittings 400 leaks, the liquid can flow along the two sub-inclined surfaces 1121c towards the through hole 120 located in the middle region at the same time, thereby improving the speed of the liquid flowing out of the liquid collecting groove 110.

[0071] As shown in the figures, Figure 5 and Figure 6 the groove bottom wall 112 further has a flat surface 1122 connected between the downhill ends 1121b of the two sub-inclined surfaces 1121c, and the through hole 120 penetrates the flat surface 1122.

[0072] In an embodiment, the connection between the inner wall surface of the through hole 120 and the flat surface 1122 has a chamfer 1123. The chamfer 1123 can be a C-angle or an R-angle.

[0073] In the embodiment of the present application, by providing the chamfer 1123 at the connection between the inner wall surface of the through hole 120 and the flat surface 1122, the speed of the liquid flowing from the flat surface 1122 into the through hole 120 can be improved.

[0074] As shown in the figures, Figure 5 and Figure 7 the side of the second part cover 140 facing the first part cover 130 has an abutting surface 142, and the second part cover 140 further has a protruding strip 141 protruding from the abutting surface 142, the first part cover 130 abuts against the abutting surface 142, and the protruding strip 141 is located on the side of the first part cover 130 where the inner wall surface is located.

[0075] In the embodiment of the present application, after the first part cover 130 and the second part cover 140 are buckled, the abutting surface 142 of the first part cover 130 abuts against the abutting surface 142 of the second part cover 140, and the protruding strip 141 is located on the side of the first part cover 130 where the inner wall surface is located, so that the sealing performance of the first part cover 130 and the second part cover 140 after buckling is significantly improved, thereby reducing the risk of liquid leakage from the gap between the first part cover 130 and the second part cover 140.

[0076] As shown in the figures, Figure 1As shown, the server cabinet further comprises a controller 20 and a sensor 300 located in the liquid collecting sleeve 100 of the liquid leakage collecting structure 30 and configured to detect whether liquid leakage occurs between the connecting portions 410 of the two pipe fittings 400 and send a liquid leakage signal, and the controller 20 is in signal connection with the sensor 300 and used to generate an alarm signal according to the liquid leakage signal.

[0077] In the embodiment, when the staff receives the alarm signal, the staff can timely go to the site for processing, and after the server is migrated, the connecting portions 410 of the pipe fittings 400 can be replaced in time.

[0078] In an embodiment, the controller 20 can be a baseboard management controller (BMC).

[0079] It is worth mentioning that the flow guide pipe 200 can discharge the liquid into the waste liquid groove at the bottom of the cabinet body 10 or directly discharge the liquid outside the cabinet body 10.

[0080] It should be noted that when the server cabinet comprises a plurality of liquid leakage collecting structures 30, the controller 20 can be in signal connection with the sensors 300 of the liquid leakage collecting structures 30 at the same time. In addition, the flow guide pipes 200 of the plurality of liquid leakage collecting structures 30 can be converged into one external pipeline, and the liquid collected by the plurality of liquid leakage collecting structures 30 can be discharged into the waste liquid groove of the cabinet body 10 or outside the cabinet body 10 through the external pipeline.

[0081] In summary, the liquid leakage collecting structure 30 and the server cabinet of the embodiment have at least the following advantages and beneficial effects:

[0082] The liquid leakage collecting structure 30 of the embodiment comprises a liquid collecting sleeve 100 sleeved on the outer periphery of the connecting portions 410 of the two pipe fittings 400 and a flow guide pipe 200 connected with the liquid collecting sleeve 100, and the liquid collecting sleeve 100 is provided with a liquid collecting groove 110 and a through hole 120.
