Abstract

The invention discloses an optimized design method for a rectangular cross-section radiator fin. The method includes the steps of obtaining the thermal conductivity of a metal material from a materialthermophysical property table according to the selected metal material of the radiator fin and an operating temperature of the fin; adopting a universal test method in heat transfer theory to obtaina natural convection surface heat transfer coefficient between the fin and the surrounding air; according to the actual needs of the radiator working environment, selecting the rib thickness and calculating the rib height; according to the heat transfer theory, obtaining a calculation formula for the heat dissipating capacity of the rectangular cross-section fin; utilizing a method of calculatingan extreme value in the calculus to make the heat dissipating capacity perform derivation on the rib thickness to zero, obtaining a transcendental equation, and using a numerical method to obtain a relation between the rib height and the rib thickness; taking the rib thickness and the rib height as a short edge and a long edge respectively; selecting the rib width according to actual requirements;and mounting the rectangular cross-section radiator fin on a radiator main body. According to the optimized design method, the cross section shape of the rib is precisely designed, to achieve the optimal effect.

Description

technical field [0001] The invention belongs to the field of radiator design, and in particular relates to an optimal design method for fins of a radiator with a rectangular cross section. Background technique [0002] The finned radiator is the most common form of radiator, which can increase the heat dissipation of the radiator by expanding the heat dissipation area. Radiator fins come in various shapes and have different heat dissipation effects. Among all fin structures, radiator fins with rectangular cross-section are the simplest and the easiest to process, so they have been widely used. For radiator fins with rectangular cross-section, when the rib width and rectangular cross-sectional area are the same, the volume of the fins is the same, and the metal consumption is exactly the same, but the shape of the rectangular cross-section is different, and the heat dissipation of the fins will be different. Therefore, from the perspective of energy saving and material savin...
