Convection Cooling of Circuit Boards
Application ID: 449
The suite of models examine the air cooling of circuit boards populated with multiple integrated circuits (ICs), which act as heat sources. Two possible cooling scenarios are depicted: vertically aligned boards using natural convection, and horizontal boards with forced convection (fan cooling). In this case, contributions caused by the induced (forced) flow of air dominate the cooling. To achieve high accuracy, the simulation models heat transport in combination with the fluid flow.
The example models the heat transfer of a circuit-board assembly using the Heat Transfer Module’s Conjugate Heat Transfer predefined multiphysics coupling. The modeled scenario is based on work published by A. Ortega.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- either the バッテリデザインモジュール, CFDモジュール, 化学反応工学モジュール, 腐食解析モジュール, 電気化学モジュール, 電気めっきモジュール, 燃料電池&電解槽モジュール, 伝熱モジュール, マイクロフルイディクスモジュール, プラズマモジュール, ポリマー流れモジュール, 多孔質媒体流れモジュール, or 地下水流モジュール
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the 製品仕様一覧 and make use of a free evaluation license.
