【摘要】 真空绝热板是一种超绝热保温材料，导热系数可以达到0.004W／(m·K)，VIP的厚度薄，一般厚度在17mm左右。这样的低导热系数保温材料的厚度比常规保温材料小的多。VIP的应用范围比较广泛，已经广泛应用到冰箱、冷库、冷藏集装箱、军队和医用保温箱等领域中。目前世界很多国家也在积极地研制真空绝热板。 真空绝热板的绝热效果与板内的真空度，隔气结构，以及芯层材料和添加剂有关，文章对真空绝热板国内外研究使用进展情况进行市场调研，对其绝热机理进行了分析，并对影响真空绝热板的导热系数的众多因素加以论述。从影响因素入手，提出了提高VIP的绝热效果的方法，对真空绝热板的设计制作和材料的选择提供了重要的理论依据。 本文设计了聚酯基薄膜真空绝热板的分步制作和多块VIP连接成集装箱绝热箱体的制作工艺；针对真空绝热板(VIP)的导热系数的测试，采用稳态平板法，设计了测试装置。采用了可调功率的恒温器，以水为冷源，在不同的功率下试验测试，可以得到比较精确的测试结果。 本文还对采用VIP板与传统的聚氨酯板的冷藏集装箱保温性能进行了分析和计算；对集装箱的节能进行分析，提出了一些措施，如在冷藏集装箱上添加经济涂层、应用数码涡旋技术等，并对新一代的冷藏集装箱和VIP在集装箱上的使用前景提出展望。更多还原

【Abstract】 Vacuum Insulated Panel is one kind of sup-adiabatic heat preservative material. The Thermal conductivity of VIP can reach to 0.004W/ (m·K) . It is very thin and the thickness is about 17mm, compared with common adiabatic material. Now it is widely used in many fields, such as refrigerator, cold store, refrigerated container, medical incubator and so on. Recently many countries are studying actively on how to manufacture the VIP.The Insulated Effect of Vacuum Insulated Panel is not only affected by the Vacuum degree in the VIP, the gatter, but also by the core material. Analyzing the adiabatic principle of the vacuum insulated panel and listing various factors that can affect its thermal conductivity, in this paper, several methods are put forward to reduce the thermal conductivity of the vacuum insulated panel.In this paper, I introduce a method of making the Vacuum Insulated Panel in the part-making way and also how to make the part-connection of VIP in the reefer wall. The method is feasible and suitable for making at domestic.Applying the steady-state-flat method, I design the apparatus for measuring thermal conductivity of the Vacuum Insulated Panel. With the constant temperature unit whose power can be changed, and chilled water as cold source, the test result is accurate under the variable power of the constant temperature unit. The apparatus can be used to check the cryogenic performance of the new VIP and the aging degree of the used VIP.In this paper, I analyze and calculate the heat-insulating property of the reefer which VIP is used on, compared with the common reefer which common insulated material such as Polyurethane (PU) is used on. Several measures of how can save energy on the reefer are also put forward in this paper, such as the economic layer,更多还原
