Embodiment Construction

[0166] A parametric rapid modeling method for a tapered corrugated-fin profile radiator. The corrugated-fin profile radiator includes a fin part and a base plate part. The fin part includes intermediate fins and edge fins. The corrugated-fin profile radiator The structural feature expression is: y=f(φ(i),φ(j),φ(k)) ; in the expression φ(i) is the functional relation of the middle fin, φ(j) is the functional relation of the substrate part, φ(k) As the functional relationship of the edge fin, the construction of the corrugated fin profile radiator model includes the following steps:

[0167] Step 1. Establish a single corrugated fin unit model. The large circle radius, small circle radius, offset distance of the center of the big and small circles in the ordinate direction, cycle period and cone angle of the corrugated fin unit are respectively R , r , Pit_ ciry , n and α , first define the coordinate system, the positive direction of the x-axis of the abscissa is to...

Abstract

The invention relates to a modeling scheme of a profile radiator, in particular to a parameterization rapid modeling method for a profile radiator with taper corrugated fins. Aiming at modeling of air-cooled fin radiators in medium and high power converter application occasions, particularly simulation modeling of tapered corrugated fin section bar radiators, a parameterized mathematical modeling method is adopted, and corrugated fin units with different radiuses and different sizes, fins with different tapers, different fin numbers and different substrate thicknesses are realized; according to the rapid modeling function of edge rib radiators with different fin offset distances and different sizes and shapes, a three-dimensional model can be automatically generated by software only by inputting key technical parameters, and the three-dimensional modeling and simulation efficiency is improved. The heat dissipation performance comparative analysis of the fin units in different shapes is facilitated, and the optimal structure scheme is determined.

Description

technical field [0001] The invention relates to a modeling scheme of a profile radiator, in particular to a parameterized rapid modeling method for a profile radiator with tapered corrugated fins. Background technique [0002] The converter device is an important part of the AC drive electrical system, and the IGBT, as its core power component, is the main heat source. High-power converters usually require high reliability, and excellent heat dissipation is an important guarantee for their normal operation. The high-loss power device is in close contact with the radiator, and the heat generated during operation is transferred to the fins of the radiator by conduction, and further transferred to the outside world through the fan. In the thermal design of electronic equipment, profile radiators have been widely used because of their simple structure, convenient processing and good heat dissipation effect. [0003] There are many factors affecting the thermal resistance of a ...
