Specifically, when the liquid cooling pipeline 220 and the liquid storage pipeline 310 are connected in series to communicate with at least three cold plates 210, the first end 321 of the liquid guide tube 320 may be communicated with the liquid storage cavity 311 between two adjacent cold plates 210, and the second end 322 may be communicated with the liquid storage cavity 311 between two adjacent cold plates 210, so that the cooling liquid leaked from the liquid cooling pipeline 220 between two adjacent cold plates 210 may pass through the liquid guide tube 320 to the liquid storage cavity 311 between two adjacent cold plates 210, and the cooling liquid may be kept in the liquid cooling device 200 and discharged outside the device, thereby avoiding the leakage of the cooling liquid.

In other embodiments, referring to fig. 5, the first end 321 of the liquid guide tube 320 is communicated with the liquid storage cavity 311, and the second end 322 of the liquid guide tube 320 is communicated with the outside, specifically, the second end 322 of the liquid guide tube 320 may be directly connected to the water inlet 231 or the water return port 232, and the first end 321 of the liquid guide tube 320 is communicated with the liquid storage cavity 311 located between the at least two cold plates 210, that is, both ends of the liquid guide tube 320 are respectively connected to the liquid storage cavity 311 located between the at least two cold plates 210 and the water inlet 231 or the water return port 232, so that the cooling liquid leaking from the liquid cooling pipeline 220 located between the at least two cold plates 210 may pass through the water inlet 231 or the water return port 232 of the liquid guide tube 320, and the cooling liquid does not leak.

By adopting the parallel connection manner, the cooling liquid may enter the plurality of cold plates 210 connected in parallel at the same time to exchange heat and cool different positions of the electronic component 110, which may improve the cooling efficiency.

In some embodiments, the ports of the reservoir 310 include a first port 312, a first end 321 of the liquid conduit 320 communicates with the reservoir 311 located on the side of the cold plate 210 far from the first port 312, and a second end 322 of the liquid conduit 320 communicates with the outside, specifically, the second end 322 of the liquid conduit 320 may directly communicate with the water inlet 231 or the water return 232, that is, when the first port 312 communicates with the water inlet 231, the second end 322 of the liquid conduit 320 may communicate with the water return 232; when the first port 312 communicates with the water return port 232, the second end 322 of the liquid guide tube 320 can communicate with the water inlet 231. In the embodiment of the present application, when the first port 312 is communicated with the water inlet 231, the second end 322 of the liquid guide tube 320 can be communicated with the water return port 232.

Specifically, first port 312 communicates water inlet 231, communicates through liquid cooling pipeline 220 and liquid storage pipeline 310 between first port 312 and parallel connection's the cold plate 210, and the both ends of catheter 320 are connected respectively and are kept away from stock solution chamber 311, water inlet 231 and return water mouth 232 of first port 312 one side, owing to adopt parallelly connected mode, when the coolant liquid leaks in the optional position, all can be through catheter 320 discharge apparatus, can not take place the coolant liquid and leak to the inside condition of equipment.

In other embodiments, the first end 321 of the liquid guide tube 320 is communicated with the liquid storage cavity 311 located on the side of the cold plate 210 close to the first port 312, and the second end 322 is communicated with the water return port 232, and due to the parallel connection mode, when the cooling liquid leaks from any position, the cooling liquid can be dispensed out of the device through the liquid guide tube 320, and the situation that the cooling liquid leaks into the device cannot occur.

It is understood that, due to the particularity of the parallel connection, when the cooling liquid leaks from any position in the liquid cooling apparatus 200, the cooling liquid will enter or exit from any one of the water inlet 231 or the water return 232, and therefore, the first end 321 of the catheter 320 can be connected to the liquid storage cavity 311 at any position.

Further, referring to fig. 6, when the cold plate 210 is connected in parallel to the liquid storage pipeline 310 through the liquid cooling pipeline 220, the liquid cooling pipeline 220 may be disposed in the liquid guide tube 320, the first end 321 of the liquid cooling pipeline 220 located in the liquid guide tube 320 is communicated with the liquid cooling pipeline 220 located in the liquid storage pipeline 310, the second end 322 of the liquid cooling pipeline 220 located in the liquid guide tube 320 is communicated with the outside through the second end 322 of the liquid guide tube 320, at this time, the liquid guide tube 320 itself also has the liquid storage cavity 311 capable of avoiding leakage of the cooling liquid, and the cooling liquid can be discharged outside the device, so as to avoid leakage of the cooling liquid to the inside of the device.

Furthermore, due to the particularity of the parallel connection, there is a possibility that more than two pipelines may be connected, and correspondingly, more than two pipelines may be communicated by using the multi-way joint 330, for example, when three liquid storage pipelines 310 and liquid cooling pipelines 220 connected in parallel are communicated at the same position, the communication may be achieved by using the three-way joint 330; as another example, when the two liquid storage pipes 310, the liquid cooling pipes 220 and the liquid guide pipe 320 connected in parallel are connected at the same position, the connection may be achieved through a tee structure. The embodiment of the present application does not limit the position and number of the multi-pass structures, and is not limited to the above examples.

It can be understood that, referring to fig. 7, the liquid cooling apparatus 200 may only adopt a serial connection mode, may only adopt a parallel connection mode, may also adopt a connection mode combining serial connection and parallel connection, and may be adjusted according to actual situations.

As an alternative embodiment, when the catheter 320 is communicated with the liquid storage cavity 311 at any position, a bonding or welding manner may be adopted, so as to prevent the cooling liquid from leaking from the position where the catheter 320 is communicated with the liquid storage cavity 311. It should be noted that the adhesive may be a gel having a water-proof property, which may reduce the possibility of leakage of the cooling fluid from the gel.

As an alternative embodiment, a sensing member (not shown in the drawings) is disposed in the liquid storage cavity 311, and the sensing member may be a liquid leakage sensor for detecting whether leakage of the cooling liquid occurs.

Further, the liquid leakage sensor may be a point type liquid leakage sensor or a rope type liquid leakage sensor. When the leakage sensor is a point leakage sensor, the optical device may be used to monitor whether leakage of the coolant occurs. When the liquid leakage sensor is a rope type liquid leakage sensor, the conductivity of the cooling liquid can be utilized to monitor whether the leaked cooling liquid exists or not.
