[0021] As Figures 1-3 shown, a multi-purpose DC-DC converter part includes a partition 1 and a coil 2. The coil 2 is mounted on the partition 1. After the coil 2 and the partition 1 are assembled, they are placed in an injection molding machine and integrally injection molded with a heat-conducting and heat-dissipating plastic material to form a heat-dissipating colloid 3. The heat-dissipating colloid 3 wraps the coil 2 and the partition 1 inside, and both ends of the coil 2 extend outside the heat-dissipating colloid 3. Instead of using additional jigs, the heat-conducting and heat-dissipating plastic material is directly injection molded with the coil. The heat-conducting and heat-dissipating plastic material is laid on the surface of the coil. After molding, the heat-dissipating colloid is in direct contact with the coil. The heat generated by the coil is directly conducted to the heat-dissipating colloid without intermediate components, improving the heat conduction efficiency. The partition can fix the coil and connect with the heat-dissipating colloid to enhance the overall strength.
[0022] The coil 2 is wound in a ring shape for several turns, and the middle area is a hollow structure. The middle area of the partition is a hollow structure, and the middle area of the coil is directly opposite to the middle area of the partition. Ensure that the side walls of the middle area of the coil can all be contacted by the heat-dissipating colloid. The area of the middle area of the hollow structure of the partition is greater than or equal to the area of the middle area of the hollow structure of the coil.
[0023] A through hole is formed in the middle area of the heat dissipation colloid 1 corresponding to the partition board, which is beneficial to air circulation, improves convection and heat dissipation performance.
[0024] A number of groove positions 4 are provided on the side of the partition board 1, and all of these groove positions are filled with a heat-conducting and heat-dissipating plastic material, which plays a fastening role.
[0025] The heat-conducting and heat-dissipating plastic material is selected from polyimide, polyether ketone, polyphenylene sulfide or polyamide.
[0026] A wiring terminal 5 is formed on the heat dissipation colloid 3, and the end of the coil extends into the wiring terminal and is led outwards, which plays a protective role for the coil and is also convenient for wiring operation.
[0027] In the present utility model, by directly contacting the heat-conducting and heat-dissipating material with the coil, the heat generated by the coil does not need to pass through an intermediate component but is directly transferred to the heat dissipation colloid and then dissipated outwards, improving the heat dissipation performance, not requiring the aid of an intermediate jig, reducing the production cost, and also being able to reduce the volume.
[0028] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
