Description
Technical Field
The invention relates to the technical field of solving liquid cooling leakage of communication equipment, in particular to a method and a device for protecting the liquid cooling leakage of the communication equipment.
Background
The traditional communication equipment is cooled and radiated by forced air, and a plurality of fans are arranged in a machine frame. Air cooling has the following problems: the energy consumption is large, the specific effective power generally exceeds 10 percent, and the requirement of green energy conservation is not met; the noise of the fan is also the most dominant source, and in most cases the only source, of the noise of the communication equipment. With the development of the technology and the development of the market, the power consumption of devices is larger and larger, the power density is continuously improved, and for high-power-consumption devices such as processors and switching chips, the bottleneck of air cooling and heat dissipation capacity can be reached after 2 years according to a technical development route diagram.
Liquid cooling technology is a technology that uses a liquid heat transfer medium with high cooling efficiency, such as water, oil or glycol, to exchange heat. Specifically, a liquid heat transfer medium flows through a heat exchanger to take away heat and then flows to a cold source to perform cold and heat exchange. Liquid cooling has the advantage over air cooling: high specific heat capacity, high heat capacity, same delta T, and more heat taken away; high thermal conductivity and quick heat transfer; the refrigeration effect is strong, and the supportable power density is high; the energy consumption is low (the power consumption for refrigeration is lower than the effective power consumption, and an outdoor cold source can adopt the environment for natural refrigeration); the device has no noise at the terminal, and only the pump of the cold source has sound (small-scale application, the cold source is in the room, the noise is small; large-scale application, the cold source is in the outdoor cooling tower, the noise has no influence, and the requirement is low).
Based on the advantages, the liquid cooling heat dissipation mode can be used for high-power equipment and devices or modules with high power density.
The heat exchange mode between the liquid heat transfer medium and the heating device has two types: direct contact immersion liquid cooling and indirect contact water cooling.
Direct contact immersion liquid cooling requires non-conducting liquid, is expensive, and is difficult to maintain and replace; and the immersed liquid cooling influences the single plate plugging and unplugging mode, and the machine frame structure needs to be completely sealed, which means that the use scene is limited. Based on these factors, immersion liquid cooling is only used in some specific areas.
At present, the liquid cooling scheme applied to communication electronic products is mainly indirect contact type water cooling, namely, heat transfer liquid flows in a pipeline and a cold plate, and the surface of the cold plate is contacted with a heating device. The heat-conducting liquid material is working medium water and is electrically conductive. While 100% reliability is not present or is too costly, in actual products, it is often a component with a failure rate within a certain range. The liquid cooling system has the possibility of failure and leakage, and the pipeline interface and the joint part of the plug quick connector are the most prone to leakage.
During the operation of the equipment, leakage or seepage inevitably occurs in the liquid cooling system (including pipelines, joints and the like). If the heat-conducting liquid falls onto the single plate, a signal short circuit occurs, and a fault occurs; if the heat-conducting liquid reaches the power module and the power line, the heat-conducting liquid can cause the short circuit, the damage and even the ignition of the power supply.
In order to avoid a series of problems caused by liquid cooling leakage, the current communication products provide some solutions.
As shown in fig. 1, the cabinet is generally fixed, and a plurality of machine frames may be arranged in the height direction of the cabinet, and each machine frame is randomly afterloaded according to the service condition. During operation of the cabinet, the newly-added machine frame is integrally inserted from front to back in the depth direction of the cabinet. In the cabinet, a certain space is reserved between every 2 frames, the front end of each frame can be used for wiring, and the rear end of each frame can be used for containing a water tray.
As shown in fig. 1 and 2b, currently, the rear end faces of all the single boards in one machine frame are flush, and all the single boards located on the same layer correspond to one backplane. As shown in fig. 1, 2a, 2b and 2c, a backplane is used to support the board and to provide power and signals (electrical signals, such as ethernet, etc.) to the board, i.e. both power and signals are provided on the backplane; in addition, the liquid-cooled blind-mate quick connectors are also mounted on the same face of the same backplane.
The structural arrangement of the single plate and the back plate in the machine frame at present and the solution of liquid cooling leakage can be obtained by combining the accompanying drawings and the structural description, and the following problems exist:
1. because the power supply, the signal and the liquid cooling quick connector are all positioned on the same surface of the back plate and are vertically distributed, when liquid leakage occurs at the liquid cooling quick connector, the liquid can be dripped onto the power supply, the circuit components of the signal, the connector and the PCB which are positioned below the liquid cooling quick connector in the process of dripping downwards, so that signal short circuit and power short circuit are easily caused.
Even if only one layer of single plate is arranged in the same machine frame, the single plate corresponds to one back plate, and the liquid cooling quick connector is arranged at the lowest part of the back plate, liquid cannot drip to the power supply and signal connector of the single plate, but the liquid cooling quick connector and the single plate electrical connector are positioned at the same side of the back plate and cannot partially seal the back plate, and the liquid can still splash onto the single plate, the power supply and the electrical connector when dripping.
Therefore, there is a safety hazard. On the one hand, traffic impairment (reliability requirements are very high in the field of telecommunications); on the other hand, if the power supply is short-circuited, fire may be caught, resulting in a safety accident, which is a more serious consequence. The risk and consequences of a failure due to a liquid leak is, to some extent, why liquid cooling is not, at times, widespread in telecommunications equipment.
2. As shown in fig. 1, even if the liquid-cooled quick connector is placed at the lowest part of the back plate corresponding to each layer of single plate, in one machine frame, there is no space for placing the water containing tray and the detection sensor between the multiple layers of single plates, so that the flow guide can not be performed for each layer of single plate, and the liquid leakage of the liquid-cooled quick connector can also drop onto the lower-layer single plate electrical connector.
3. One machine frame can only be correspondingly provided with one water containing disc, and the leakage detection depends on additional equipment of an external machine cabinet. The detection and treatment scheme of the leakage liquid is as follows: if only one local leakage is monitored, the whole cabinet is shut down immediately. The local fault has a large influence range.
