冷热冲击试验机结构

1、试验箱结构形式：试验箱采用整体式组合结构形式，既试验箱由位于上部的高温试验箱，位于下部的低温试验箱体、位于后部的制冷机组柜和位于左侧后板上的电器控制柜（系统）所组成。此方式箱体占地面积小、结构紧凑、外形美观，制冷机组置于独立的机组箱体内，以减少制冷机组运行时的震动、噪声对试验箱的影响，同时便于机组的安装和维修，电器控制面板置于试验箱的左侧板上以便于运行操作。    
2、箱体外壁材料：优质碳素钢板，表面作静电彩色喷塑处理。                                                                                                                                                                                                                                                                                                                      3、箱体内壁材料：进口SUS304不锈钢板，耐腐蚀、易清洗、美观大方。    
4、保温材料：优质超细玻璃纤维棉。
