The invention belongs to the field of refrigerated carriages, and particularly relates to a brand-new open type foaming process refrigerated carriage and carriage body plate structure and a manufacturing process thereof.The refrigerated carriage body is composed of a bottom plate, side plates, a top plate and a front plate, the side plates are arranged on the two sides of the top of the bottom plate, the top plate is arranged over the bottom plate, and the top plate is located at the tops of the side plates; according to the invention, a secondary pouring foaming refrigeration compartment body splicing process is adopted, open foaming process cold-bridge-free structural plates are adopted in a plate structure, and the interior and the exterior of the refrigeration compartment body are spliced in a manner of riveting aluminum alloy sections of a special two-sealant groove structure; and the side plates are arranged on the two sides of the bottom of the top plate, and the front plate is arranged at the front end of a frame body formed by the bottom plate, the side plates and the top plate. Secondary high-pressure pouring foaming is carried out in a closed cavity formed at the connecting positions of all the plates, polyurethane foam layers of all the plates of the compartment body form a closed-loop structure, the overall air tightness and heat preservation performance of the compartment body are greatly improved, and the heat conductivity coefficient of the whole compartment is 0.03 or below.

    本发明属于冷藏车厢领域,具体的说是一种全新的开式发泡工艺冷藏厢及厢体板材的结构及其制造工艺,该冷藏箱体由底板、侧板、顶板和前板组成,底板顶部的两侧设置有侧板,底板的正上方设置有顶板,顶板位于侧板的顶部,且顶板底部的两侧设置有侧板,底板、侧板和顶板组成的框体前端设置有前板,本发明通过二次灌注发泡冷藏厢体拼装工艺和板材结构采用开式发泡工艺无冷桥结构板材、内外采用专用两道密封胶槽结构的铝合金型材铆接的方式拼装,在所有板材连接处形成的密闭空腔内进行二次高压灌注发泡,厢体所有板材的聚氨酯泡沫层形成闭环结构,厢体整体气密性和保温性大大提高,整厢导热系数在0.03以下。
