Metal stamping plant first brand [Branch] Shenzhen Branch precision molds metal factory is a metal stamping and production-oriented enterprises, Main: various types of precision metal stamping dies, metal stamping shrapnel, auto metal parts, precision pull stretch, metal clips, heat sinks, mobile power shell. And to provide design and drawing services, reduction in product design changes, shorten the development cycle to address mold and part design and processing to worry about, so that products to market faster. The factory has advanced mold design software and advanced design engineers, mold manufacturing technicians, relying on professional design technology, combined with years of practical experience, quality of quality-based, market demand-oriented, won recognition at home and abroad and support. ?????? Fin design which factors should be considered below it on the heat sink, Zhongshan factory to serve you on the next:? 1, the heat sink surface treatment: do acid aluminum heat sink surface (Alumite) or anodized to increase radiation performance and increase the heat sink thermal performance, in general, and the color is not white or black relationships. Surface treatment increases the cooling area projections, but in the case of natural convection, but may result in obstruction of the air layer, reducing efficiency. 2, the envelope volume in terms of heat sink design, here a simple method, that is, the concept of the volume of the envelope, the so-called enveloping volume means the volume occupied by the heat sink, if the heating power, the heat required piece volume is relatively large. Heat sink design envelope volume may make a preliminary design, and then on the heatsink fins and details such as the size of the bottom of the detailed design. 3, such that the thickness of the bottom of the heat sink fin efficiency increases, has a great influence fin sole thickness, the bottom of the heat sink must be thick enough to make sufficient thermal energy is transmitted to all the fins smoothly, so that all fins have the best The utilization efficiency. However, apart from the bottom of the waste material is too thick, but can also cause the accumulation of heat heat transfer ability. Good design thickness of the bottom edge portion must be thinned to the thick portion from the heat source, such that the total portion of the heat sink by the heat source rapidly absorb enough heat transfer to the surrounding thinner part. Foshan heatsink manufacturers of the products, have improved the production process and quality system to ensure product quality. We sincerely hope to provide high quality and perfect service for your company to become your loyal and long-term partner.
