Title (EN) HEAT-SINK-MOUNTED INDUCTOR
(FR) INDUCTEUR MONTÉ SUR UN DISSIPATEUR THERMIQUE
(JA) 放熱板付インダクタ
Abstract:
(EN) Provided is a heat-sink-mounted inductor that exhibits an excellent temperature-lowering effect by suppressing heat generation in a heat sink due to electromagnetic induction of magnetic flux leakage. This heat-sink-mounted inductor is provided with: a core (2); a coil (4) wound around the core (2); and a heat sink (5) which is made of a magnetic material and which is disposed directly or indirectly in contact with the coil (4) so as to release heat from the core (2) and the coil (4) to outside. The heat sink (5) has at least one opening that connects the coil side-facing surface thereof and the surface opposite thereto, and that reduces the heat generated by electromagnetic induction of the heat sink (5).
(FR) La présente invention concerne un inducteur monté sur un dissipateur thermique qui présente un excellent effet de réduction de la température en supprimant la génération de chaleur dans un dissipateur thermique due à l'induction électromagnétique d'une fuite de flux magnétique. Cet inducteur monté sur un dissipateur thermique est pourvu : d'un noyau (2) ; d'une bobine (4) enroulée autour du noyau (2) ; et d'un dissipateur thermique (5) qui est constitué d'un matériau magnétique et qui est disposé directement ou indirectement en contact avec la bobine (4) de façon à libérer de la chaleur du noyau (2) et de la bobine (4) vers l'extérieur. Le dissipateur thermique (5) présente au moins une ouverture qui relie sa surface tournée vers le côté de la bobine et la surface opposée à cette dernière, et qui réduit la chaleur générée par induction électromagnétique du dissipateur thermique (5).
(JA) 漏れ磁束の電磁誘導による放熱板の発熱を抑えて、温度低下効果に優れた放熱板付インダクタを提供する。放熱板付インダクタは、コア(2)と、このコア(2)に巻回されたコイル(4)と、このコイル(4)に直接または間接的に接触してコア(2)およびコイル(4)の熱を外部に放出する放熱板(5)であって、磁性体からなる放熱板(5)とを備える。放熱板(5)は、コイル側を向く面とその反対側の面とに連通しこの放熱板(5)の電磁誘導による発熱を低減させる少なくとも1つの開口を有する。
