Description
Technical Field
The invention belongs to the technical field of radiators, and particularly relates to an inner and outer double-layer efficient radiator with adjustable distance between radiating fins.
Background
The heat sink is used to prevent the device from overheating and to conduct heat generated by the electrical or electronic components connected to the heat sink to the air. The larger the surface area of the heat sink in contact with the air, the greater the amount of heat transferred to the air and thus the better the cooling effect of the device. Other factors that affect the heat dissipation efficiency of a heat sink are the flow rate of air, the design structure, the materials used, the surface treatment performed, the manner in which the electrical or electronic device is connected to the heat sink, and so forth.
One of the most common design features in the manufacture of heat sinks is the placement of fins around an axis. Heat sinks of this type typically have a central body for absorbing heat dissipated by one or more electrical or electronic components, and a plurality of fins extending from the body and radially distributed about an axis to dissipate the heat absorbed by the body into the air. To enhance the heat absorption of the core and the heat transfer to the fins, materials with high thermal conductivity are often used, such as aluminum or copper, among others.
These heat sinks usually have geometrically uniform fins distributed around the central body in given positions equal to each other. To facilitate the fabrication of the heat sink using an extrusion process, the heat sink must have a fixed cross-section along the extrusion axis. For this reason, the walls constituting the fins are arranged parallel to each other, and there is no inclination between any adjacent fins. In other words, all the fins are parallel to each other along the extrusion axis, the air flow channels defined between the fins having a constant cross section. Generally, the extrusion process requires large machinery and high maintenance costs, which can be slow when high impact forces are required to pass the material through the die, leave impurities and defects on the surface of the extruded material, and severely limit the geometry of the component since it must have a constant cross-section along the extrusion axis. On the other hand, manufacturing processes using injection molding are more flexible in terms of the variety of shapes and geometries that can be obtained, and they are generally faster to produce, less costly, and generally more finished in the surface finish of the resulting component.
However, in all the existing heat sinks, the heat dissipation fins and the base body are connected together, so that the heat dissipation performance of the heat sink is determined, and the heat dissipation performance cannot be flexibly adjusted according to the heat productivity of the heat generating equipment.
