摘要
本課題主要研究冬季家庭供暖設施的設計，其中包括對供暖房間的耗熱量計算以及對熱源供暖鍋爐設計。在對供暖設施的主體燃氣鍋爐設計時，運用Pro/Engineer軟件對其進行設計，包括對燃氣鍋爐的各部分零件進行三維造型以及整機裝配，最后對主要零件進行工藝設計。燃氣鍋爐是一種常用的供暖設備，它有燃燒器、換熱器、膨脹水箱、水泵和電路板等幾部分組成，其設計涉及材料、力學、幾何公差、供熱等多類知識。以前，對鍋爐的設計以手工為主，設計周期長，設計工作效率低，但隨著計算機技術的迅速發展，計算機輔助設計和輔助制造技術（CAD/CAM）得到了廣泛的應用，采用Pro/Engineer軟件可大幅度縮短燃氣鍋爐的設計周期，降低成本，提高了設計效率和質量，并使設計更加科學。

Abstract
The study of this paper is the design of the warm facilities for the family  in  winter , it include acquiring the data that consuming calories of the room and design of the warm boiler, including use Pro/Engineer to model every parts of the boiler and fabricate the boiler, and then chose the main parts to design its craft.the warm boiler including burner、Change a hot machine、Inflate water tank 、The water pump 、Circuit board and so on, its design involves many kinds of knowledge such as  material, mechanics, Several business trips ,provide warm and so on. Some times ago,the design of warm boiler was finished mostly by manual,the time of design was long and the design efficiency was low,but along with fast development of the computer and information, Computer Aided Design and Computer Aided Manufacturing (CAD/CAM) is been widely used in all areas.According to the general design steps of warm boiler and the result of design,my design can shorten largely the design of warm boiler,reduce cost,improve design efficiency and product quality,and make the design more scientific by using  Pro/Engineer soft.
