Claims (7)

1. Система охлаждения (10), предназначенная для охлаждения электронной аппаратуры, например, приборов авионики, содержащая
по меньшей мере один пластинчатый элемент (12), образующий стенку кожуха, в котором предполагается устанавливать электронную аппаратуру, упомянутый по меньшей мере один пластинчатый элемент имеет первую сторону (12а), обращенную в сторону аппаратуры, и вторую сторону (12b), противоположную первой стороне (12а), и контур текучей среды (14), образующийся в упомянутом по меньшей мере одном пластинчатом элементе (12),
отличающаяся
тем, что первый контур текучей среды (14) содержит первый проток (14а), образующийся на первой стороне (12а) упомянутого по меньшей мере одного пластинчатого элемента (12) и проходящий по первому лабиринту, и второй проток (14b), образующийся на второй стороне (12b) упомянутого по меньшей мере одного пластинчатого элемента (12) и проходящий по второму лабиринту, и
тем, что упомянутый по меньшей мере один пластинчатый элемент (12) имеет первое сквозное отверстие (18) и второе сквозное отверстие (20), через которые сообщаются первый проток (14а) и второй проток (14b), и
тем, что контур текучей среды (14) также содержит пористый разделительный элемент (22), размещаемый в первом сквозном отверстии (18), через которое текучая среда благодаря капиллярному натяжению перетекает из второго протока (14b) в первый проток (14а), текучая среда находится в газообразном состоянии в первом протоке (14а) и в жидком состоянии во втором протоке (14b).
2. Система охлаждения по п. 1 также содержит первую пленку (16а), прикрепленную к первой стороне (12а) упомянутого по меньшей мере одного пластинчатого элемента (12), для герметизации первого протока (14а), а также первое и второе отверстия (18 и 20) на той же стороне, что и первая сторона (12а), и вторую пленку (16b), прикрепленную ко второй стороне (12b) упомянутого по меньшей мере одного пластинчатого элемента (12), для герметизации второго протока (14b), а также первое и второе отверстия (18 и 20) на той же стороне, что и вторая сторона (12b).
