Definitions

  • the utility model belongs to the field of electronic components, in particular to a device with a heat sink, the device being a transformer or an inductor.
  • the general heat dissipation methods are as follows: one is air-cooled heat dissipation, the other is natural heat dissipation, and the third is The magnetic core is attached to the casing to dissipate heat.
  • the above several ways can only dissipate heat from the core and the winding surface.
  • the internal heat can only be radiated through the inductor body or the transformer body to the surface, due to the heat conduction of the inductor and the transformer body.
  • the purpose of the utility model is to provide a device with a heat sink with high heat dissipation efficiency and simple and practical structure for the heat dissipation defects of the inductor and the transformer.
  • the utility model comprises a device body, the device body is a transformer body or an inductor body, and the utility model further comprises a heat sink and two or more heat conduction strips, one end of the heat conduction strip is fixed on the device
  • the inside of the body has a fixed connection to the heat sink at the other end.
  • the heat conducting strip and the heat sink are fixedly connected by screws, and a fixing hole is disposed on one end of the heat conducting strip and the heat sink.
  • the number of fixing holes on the heat conducting strip and the heat sink is two to several, and correspondingly, the number of the screws is two to several, so that the heat conducting strip and the heat sink are well connected.
  • a thermal conductive adhesive is disposed between the heat sink and the device body and between the heat conducting strip and the heat sink, which can increase the contact area and the heat conducting effect between them, thereby increasing the heat dissipation effect.
  • one end of the heat conducting strip is closely attached to the winding of the transformer body or is closely adjacent to the winding of the inductor body and the magnetic core.
  • the utility model has a heat sink externally on the device, and the heat inside the device is guided to the outer heat sink through the heat conduction strip, thereby achieving the purpose of guiding the internal heat to the outside, and the heat dissipation effect Good, and the structure is simple.

Abstract

L'invention concerne un dispositif avec un radiateur. Le dispositif comprend un corps de dispositif consistant en un corps de transformateur ou un corps d'inducteur. Le dispositif comprend également un radiateur (4) et deux bandes conductrices de chaleur (2) ou plus. Une extrémité de la bande conductrice de chaleur (2) est fixée à la partie interne du corps du dispositif, et l'autre extrémité est connectée au radiateur (4). Selon la présente invention, un radiateur peut être disposé sur la partie externe d'un dispositif, et la chaleur peut être transférée vers le radiateur externe depuis la partie interne du dispositif par la bande conductrice de chaleur, la chaleur étant ainsi transférée vers la partie externe depuis la partie interne. L'effet rayonnant est bon et la structure est simple.
