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.
