Investigating the Effects of Conductor Types of Induction Coil on Performance of the Induction Liquid Heater

Öz

In residential and industrial applications, the usage of induction liquid heater using induction heating principles is increasingly growing due to having some advantages. One of the components of the induction heating is induction coil. Because of working best at resonance condition and carrying a lot of current, induction coils are constituted from a wire having a big cross-sectional area; and also have a few turn. At present, there are a lot of wire types being used in induction coil design. In this study, by using the COMSOL® Multiphysics software, 3D solid models of a total of eight-induction-coil designed with different wire types are created; magnetic and thermal analysis of those are performed under identical environmental conditions for different working frequencies; and, performance tests of induction heaters are done by computing the heating-power on induction apparatus. This study, also, aims to help designer and manufacturer on choosing favorable wire type for induction coil design.

İndüksiyon Bobin Tasarımında Kullanılan İletken Türlerinin İndüksiyon Sıvı Isıtıcı Performansına Etkilerinin Araştırılması

Öz

Sahip olduğu bazı üstünlükler dolayısıyla, indüksiyon prensibiyle sıvı ısıtma sitemlerinin endüstriyel ve evsel kullanımı giderek artmaktadır. İndüksiyon sıvı ısıtma sistemlerinin en önemli unsurlarından biri indüksiyon bobinleridir. İndüksiyon bobinleri, rezonans durumunda en verimli çalıştıkları ve büyük akımlar taşıdıkları için, büyük kesitli iletkenlerden az sipirli sarılarak oluşturulurlar. Günümüzde, indüksiyon bobin tasarımında kullanılabilecek birçok iletken türü mevcuttur. Bu çalışmada, COMSOL® Multiphysics yazılımı kullanılarak, 8 farklı iletken türünden oluşturulan indüksiyon bobinlerinin 3B katı modelleri oluşturulmuş, eşit çevresel faktörler ve farklı çalışma frekansları için 2B manyetik ve termal analizleri gerçekleştirilmiş, ısıtıcı aparat üzerinde açığa ısıtma gücü hesaplanarak ısıtıcı performans testi yapılmıştır. Bu çalışma aynı zamanda tasarımcı ve üretici firmalara, indüksiyon bobin tasarımında kullanılabilecek iletken türü seçiminde yardımcı olmayı da amaçlamaktadır.
