Title (EN) OUTDOOR UNIT OF REFRIGERATION APPARATUS
(FR) UNITÉ EXTÉRIEURE D’APPAREIL DE RÉFRIGÉRATION
(JA) 冷凍装置の室外ユニット
Abstract:
(EN) The present invention prevents a fire that has started outside an outdoor unit of a refrigeration apparatus from spreading to a substrate in an electrical component box, and at the same time to prevent a decline in the cooling function of a heat sink attached to the substrate due to fire spread prevention measures for the substrate. Support pieces (41g, 41h, 41i) being metallic catching members catch a heat sink (51) that has come off a printed circuit board in the event that the interior of an outdoor unit (10) burns as a result of, for example, catching fire. The regions of the support pieces (41g, 41h, 41i) that lie directly beneath the heat sink (51) are configured to have an area size, as viewed from above, that is less than 10% of the area size of the heat sink (51) as viewed from above.
(FR) La présente invention empêche un incendie qui a commencé à l’extérieur d’une unité extérieure d’un appareil de réfrigération de se propager à un substrat dans un boîtier de composants électriques, et simultanément pour éviter une dégradation de la fonction de refroidissement d’un dissipateur thermique fixé au substrat due à des mesures de prévention de propagation d’incendie pour le substrat. Des pièces de support (41g, 41h, 41i) qui sont des éléments de capture métalliques retiennent un dissipateur thermique (51) qui s’est détaché d’une carte de circuit imprimé dans le cas où l’intérieur d’une unité extérieure (10) brûle en conséquence, par exemple, d’un embrasement. Les régions des pièces de support (41g, 41h, 41i) qui sont situées directement sous le dissipateur thermique (51) sont configurées de façon à avoir une taille d’aire, telle qu’observée depuis le dessus, qui est inférieure à 10 % de la taille d’aire du dissipateur thermique (51) telle qu’observée depuis le dessus.
(JA) 冷凍装置の室外ユニットの外部で発生した火災によって電装品箱の基板まで延焼が及ぶのを抑制するとともに、基板に取り付けられているヒートシンクの冷却機能が基板の延焼対策が原因で低下するのを抑制する。金属製の捕獲部材である支持片(41g,41h,41i)は、ヒートシンク(51)が、例えば火災などによって室外ユニット(10)の内部が燃えることにより、プリント配線基板から外れたときに、外れたヒートシンク(51)を受け止める。ヒートシンク(51)の真下に位置する支持片(41g,41h,41i)の部位の上面視における面積が、ヒートシンク(51)の上面視における面積の10%未満となるように構成されている。
