摘要： A liquid leakage detection apparatus configured for liquid leakage detection of a liquid cooling apparatus of a printed circuit board is provided. The apparatus includes a sleeve (21), a first liquid cooling pipe (11), a liquid cooling plate (12), flow guiding apparatuses (22, 27), and a liquid leakage detection circuit (25). The sleeve (21) wraps the first liquid cooling pipe (11), the first liquid cooling pipe (11) is connected to the liquid cooling plate (12), the liquid cooling plate (12) and the first liquid cooling pipe (11) are configured to dissipate heat for an electronic element (13) by using a filled coolant, the flow guiding apparatuses (22, 27) are connected to an edge of the liquid cooling plate (12), the other ends of the flow guiding apparatuses (22, 27) are connected to the liquid leakage detection circuit (25), and the flow guiding apparatuses (22, 27) are configured to guide first leaked liquid occurring in the first liquid cooling pipe (11) and/or second leaked liquid occurring in the liquid cooling plate (12) to the liquid leakage detection circuit (25). The sleeve (21) is used to wrap the first liquid cooling pipe (11), and the flow guiding apparatuses (22, 27) are used to guide the first leaked liquid and/or the second leaked liquid to the liquid leakage detection circuit (25), so that the liquid leakage detection circuit (25) can detect that the liquid cooling apparatus leaks before the first leaked liquid and/or the second leaked liquid overflow to the electronic element (13), thereby improving security of this solution.

摘要： Une installation contient un réservoir de dihydrogène et/ou un circuit de dihydrogène, et un dispositif de régulation d'une concentration en dihydrogène situé à l'extérieur du réservoir et/ou du circuit. Le dispositif comprend au moins une paire (2) de conducteurs électriques (4, 6) comprenant un premier conducteur électrique (4) alimenté avec une première tension électrique (U4) et un deuxième conducteur électrique (6) alimenté avec une deuxième tension électrique (U6) différente de la première tension électrique (U4). Au moins un contrôleur commande de façon répétitive l'application d'une différence prédéterminée de tension électrique entre le premier conducteur électrique (4) et le deuxième conducteur électrique (6) de façon à ce qu'un arc électrique de puissance contrôlée se forme pour brûler le dihydrogène émanant éventuellement du réservoir et/ou du circuit. Ainsi, le dihydrogène ne vient pas s'accumuler dans des endroits non désirés de l'installation.

摘要： A detection device (20) for battery cells (10) comprises a detection bench (21), a heating apparatus (22) and a detection apparatus (23). The detection bench (21) is provided with an accommodating cavity (21a), the accommodating cavity (21a) being used to accommodate a battery cell (10). The heating apparatus (22) is provided in the accommodating cavity (21a) and used to heat the battery cell (10). The detection apparatus (23) is in communication with the accommodating cavity (21a) and used to detect the composition of gas in the accommodating cavity (21a) to determine whether an electrolyte solution of the battery cell (10) leaks. In the detection device, the battery cell (10) is placed in the accommodating cavity (21a), and the heating apparatus (22) is used to heat the battery cell (10) in the accommodating cavity (21a) to accelerate the vaporization of the electrolyte solution in the battery cell (10) in which electrolyte solution leakage exists and the release into the accommodating cavity (21a), so as to achieve fast and efficient detection of whether the electrolyte solution in the battery cell (10) leaks or not without affecting the structure and performance of the battery cell (10) itself, thereby ensuring the safety of the battery cell (10).
