Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transformers, in particular to a high-frequency small planar transformer. BACKGROUND

[0002] A transformer is a kind of static electrical equipment based on electromagnetic induction principle, used for adjusting alternating current voltage and current. In order to adapt to the development trend of power electronic technology towards high frequency, miniaturization and integration, a planar transformer needs to use a multi-layer printed circuit board or a flat copper sheet as a winding, and install a magnetic core on the PCB. This design effectively improves the performance, consistency and power density of the transformer in a high-frequency environment. However, the existing planar transformer has the following disadvantages:

[0003] The transformer in the prior art pursues high power density, resulting in a small device size, but the heat is concentrated, which easily causes the local temperature to be too high, thereby affecting the performance of the magnetic core and the winding, and even damaging the components. The use of integrated, binding or glueing methods for reinforcement can easily cause insufficient anti-vibration and impact resistance, and it is difficult to maintain and replace. In addition, the rigid pins directly welded under the dual action of thermal stress and mechanical stress can easily produce micro-cracks at the welding points or the root of the pins, and even break, thereby shortening the service life. In order to adjust the interlayer capacitance of the transformer, the prior art presses different types and quantities of semi-cured sheets and substrates under high temperature and high pressure. The resin in the semi-cured sheet flows and completely fills the gap, and finally solidifies to form a solid multilayer board. However, this design cannot be changed once it is finalized, lacks flexibility, and the thermal conductivity of the resin is poor, resulting in that the interlayer heat transfer mainly depends on the thermal vias, which affects the heat dissipation efficiency.

[0032] Embodiment 1, according to Figures 1-4As shown, the inner side of the upper magnetic core 102 and the lower magnetic core 101 is sleeved with a support column 103, and the cooling mechanism 2 comprises a cavity network 201 installed at the bottom end of the upper magnetic core 102, a condenser 202 installed at the inner side of the upper magnetic core 102, a conveying pipe 203 installed at both sides of the outer surface of the condenser 202, a water pump 204 installed at one side of the outer surface of the conveying pipe 203, and the other end of the outer surface of the conveying pipe 203 is installed at the top end of the cavity network 201, a cooling fin 205 installed at the inner side of the condenser 202, a movable frame 206 slidably connected to the top end of the lower magnetic core 101, a sliding groove 207 formed in the top end of the lower magnetic core 101 and the movable frame 206, a first spring 209 fixedly installed at the inner bottom end of the sliding groove 207, a pull block 208 fixedly installed at one end of the outer surface of the first spring 209 close to the top end of the movable frame 206, a positioning groove 210 formed in both sides of the top end of the upper magnetic core 102, an insertion block 211 slidably connected to the inner side of the positioning groove 210, a groove formed in the outer surface of the support column 103, the cavity network 201 sleeved on the outer surface of the support column 103, and the inner side of the cavity network 201 filled with high-performance fluorinated liquid, the substrate 104 sleeved on the outer surface of the cavity network 201, and the insertion block 211 respectively installed at the bottom end of the pull block 208 and one side of the outer surface of the movable frame 206, and the insertion block 211, the pull block 208 and the movable frame 206 arranged in an inverted L shape to limit the horizontal and vertical movement of the upper magnetic core 102.
