Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Example 1

Referring to fig. 1-4, the present embodiment provides a heat sink, which includes a central supporting body 1 and heat conducting fins 2 disposed on the periphery of the supporting body 1, wherein the supporting body 1 is provided with a terrace surface 121 for adhering to the polar surface of the diode, and the terrace surface 121 is disposed on the edge of the peripheral outline of the whole heat sink. The whole radiator is of a rectangular structure.

The support body 1 includes a base support portion 11 and reinforcing support portions 12 projecting from the base support portion 11 to opposite sides thereof. The support body 1 is an integral solid body. The base support 11 has a rectangular body structure with a length and width equal to those of the entire heat sink. The reinforcing support portion 12 is a rectangular frustum structure, and the platform surface 121 is a surface where two reinforcing support portions 12 deviate from each other.

The whole radiator all-in-one machine is formed in an additive mode, and the process is also a necessary choice for the production process of the radiator in the embodiment. Since the prior art heat sink is elongated, the profile is typically extruded and drawn, and the shape of the heat sink in this embodiment is not producible by this process. In addition, although casting can be used for production, casting technology is generally not considered in the prior art due to process defects such as air holes, poor metal performance, uneven strength and the like caused by the casting technology.

Due to the arrangement of the supporting body 1, the force for extruding the diode directly acts on the supporting body 1, and the bearing capacity of the whole radiator can be obviously improved.

In practical implementation, the heat sinks in this embodiment are installed in three-phase rectifiers, a flat diode is arranged between two adjacent heat sinks, and the flat platform surfaces 121 of the two heat sinks clamp the diode. Because the clamping force is larger, the contact between the diode and the heat sink is more sufficient, so that the overcurrent is larger, and the performance of the whole device is better. As for the reason that the conventional diode is not in contact with the rectifier, the diode is usually burned out in the prior art, and the diode after being shipped from the factory has a certain radian, so that compared with the prior art, the performance of the rectifier device can be improved by increasing the clamping force, and therefore, the performance of the heat sink in this embodiment can be improved for the three rectifiers.

Example 2

This embodiment proposes a three-phase rectifying device, which includes a base and an upper cover, wherein a plurality of radiators as described in embodiment 1 above are disposed between the base and the upper cover, and a diode is disposed between any two adjacent radiators.
