The water cooling pipeline is provided with a water cooling pipeline, a water absorption coating layer is coated outside the water cooling pipeline, and cooling liquid flowing out from a leakage point on the water cooling pipeline can be absorbed by the water absorption coating layer and diffused in the water absorption coating layer. The detection element is clamped between the water cooling pipeline and the water absorption coating layer or embedded in the water absorption coating layer, and is used for detecting the cooling liquid absorbed in the water absorption coating layer and outputting a corresponding detection signal.
The arrangement of the device in a water cooling system is beneficial to the safety protection of cooled electrical parts or equipment, and the damage caused by the leakage of cooling liquid is reduced.
Based on the general configuration principle described above, the present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. For convenience of understanding and description, the water cooling pipeline leakage detection device will be described below by taking the device as an example applied to a water cooling system in a battery pack of a power automobile, and an exemplary configuration of the water cooling pipeline leakage detection device applied to the battery pack is shown in fig. 1.
In the battery pack 9, a plurality of sets of battery modules 8 are arranged in an array, in order to cool each battery module 8, a cooling loop is arranged inside a housing of each battery module 8, meanwhile, a liquid inlet pipe 102 and a liquid return pipe 103 are connected to the housing of the battery module 8, a circulation unit 104 of a water cooling system is arranged in the battery pack 9, so that the cooled coolant 100 is pumped out from the liquid inlet pipe 102, and the coolant 100 flows through the cooling loop in the battery module 8 and then flows back to the circulation unit 104 from the liquid return pipe 103.
The water cooling pipelines 1 for the liquid return pipe 103 and the liquid inlet pipe 102 are generally arranged by copper pipes with good heat conductivity. The leakage is likely to occur at the water cooling pipeline 1 in the liquid return pipe 103 and the liquid inlet pipe 102. The water-cooling pipeline leakage detection device of the embodiment mainly detects leakage of the water-cooling pipeline 1.
As shown in fig. 2, the device mainly comprises a water absorption coating layer 3 and a detection element 2, wherein the water absorption coating layer 3 is coated outside the water cooling pipeline 1 to comprehensively coat the water cooling pipeline 1, and the water cooling pipeline can be set by adopting a pipeline heat insulation construction process. Meanwhile, the water absorbing coating layer 3 is made of a water absorbing material with good hydrophilicity, and can also take heat insulating performance into consideration, such as an inorganic heat insulating material, and sponge, preferably glass wool. The water-absorbing coating layer 3 is formed by glass wool, so that the water-absorbing coating layer has good water absorption performance and good heat insulation performance, and the cooling efficiency of a water cooling system is improved.
As shown in fig. 3, when a leak 101 occurs in the water cooling line 1, the coolant 100 flowing out of the leak 101 may be adsorbed by the water-absorbing coating 3 and diffused in the water-absorbing coating 3; the detection element 2 is arranged between the water cooling pipeline 1 and the water absorption coating layer 3 or embedded in the water absorption coating layer 3, and when the cooling liquid 100 diffuses to the position of the detection element 2, the detection element 2 detects the leakage of the cooling liquid 100 in the water absorption coating layer 3. The signals of the detection elements 2 can be fed to the control unit via the wired lines 200. The control unit may be the leak detection controller 6 provided for the detection element 2, or may be the battery pack management system 7 of the battery pack 9. The leakage detection controller 6 or the battery pack management system 7 receives the leakage detection signal and sends out corresponding warning or instruction according to the signal change condition, so that people can know the leakage condition of the cooling liquid 100 in the battery pack 9 in time.
In order to form comprehensive detection on each section of water cooling pipeline 1 in the water cooling system, correspondingly, a plurality of detection elements 2 are arranged and respectively arranged on each section of water cooling pipeline 1 in the water cooling system, so that the liquid leakage condition of the water cooling system can be found in time.
The detection element 2 can be a humidity sensor, and the leakage of the cooling liquid 100 is judged according to the humidity change in the water absorption coating layer 3; and a positioning water leakage induction line can also be adopted to detect liquid leakage. The liquid leakage condition of the water cooling pipeline 1 is detected by adopting the humidity sensor to distribute multiple points, measuring points can be flexibly arranged aiming at the pipeline area which is easy to leak, and the flexible and reasonable configuration of the detection device is convenient. And use the induction line that leaks of location, can form and to the more comprehensive detection of water cooling pipeline 1 cover, simultaneously, through leak hunting controller 6 received signal and send control command, action such as warning or power-off protection that can in time form to leaking makes the promptness and the validity of weeping detection further improve.
When the positioning water leakage sensing line is used as the detecting element 2, the detecting elements 2 of the respective stages are connected to each other via the jumper cable 600, and finally, the detecting elements 2 are connected to the leakage detecting controller 6. The positioning water leakage induction line has various existing mature products, for example, Shenzhen Shenxiang is an XW cooling liquid 1000 positioning water leakage induction line produced by measurement and control technology Limited company, and the leakage detection controller 6 can be matched with an XW-PC-3A band display leakage detection controller produced by the same company. With this configuration, the leakage occurring on the water cooling pipeline 1 and the specific position of the leakage point 101 can be detected and known.
There are two main options for the position of the detection element 2 on the water cooling line 1. The first method is to embed the detection element 2 in the water-absorbing coating layer 3 in advance so as to complete the setting of the detection element 2 synchronously with the coating and installation of the water-absorbing coating layer 3.
