真空绝热板及冰箱
摘要：
本发明提供了一种一种真空绝热板，其包括：芯材，所述芯材包括玻璃纤维层以及开孔泡沫层，所述玻璃纤维层与所述开孔泡沫层层叠设置，所述开孔泡沫层的背离所述玻璃纤维层的表面形成凹槽结构；包覆材料，包裹所述芯材，与所述芯材之间形成真空，从而在所述凹槽结构的对应位置上形成用于布置外部的换热管路的容纳部。这样的结构可以避免芯材的玻璃纤维层中的玻璃纤维碎片较多，防止真空绝热板的包覆材料被破坏，防止真空绝热板失效，且降低真空绝热板的导热系数。
摘要（英）：

The invention provides a vacuum insulated panel. The vacuum insulated panel comprises a core material and a clad material. The core material includes a glass fiber layer and a perforated foam layer, and the glass fiber layer and the perforated foam layer are arranged layer by layer in an overlaying mode, and groove structures are formed in the surface, deviating from the perforated foam layer, ofthe glass fiber layer. The clad material wraps the core material, vacuum is formed between the clad material and the core material, and containing parts for arranging external heat exchange pipelinesare arranged at the corresponding positions of the groove structures. The structure can avoid more glass fiber fragments in the glass fiber layer of the core material, prevent the clad material of thevacuum insulated panel from being destroyed, prevent the failure of the vacuum insulated panel, and reduce the thermal conductivity of the vacuum insulated panel.
