The analysis of structure of liquid nitrogen tank YDS series 




















产品主要结构及其特点(Main structure and Features)
YDS系列产品主要由外壳、内胆、颈管、多层绝热体、提筒等组成，其中航空运输系列产品另含液氮吸附体。
YDS-series products are mainly made up of outer shell, inner tank, neck tube, multi-layer isolating material and canister. Otherwise, dry shipper series include liquid nitrogen absorbent. (frag. 2)
 
1. 容器外壳、内胆采用铝合金板制作，具有重量轻、低温下强度高、耐腐蚀等特点。
The outer shell and inner tank are made of the aluminum alloy plate, featuring on light weight, high cryogenic, high strength and corrosion resistance.
 
2. 颈管采用玻璃钢制作，具有机械强度高、导热系数小等特点。
The neck tube is made of glass-fiber reinforced plastics, featuring on high mechanical strength and low heat conductivity.
3. 多层绝热体采用反射性能特别优良的铝箔为反射屏，采用导热系数小，放气速率低的材料为隔热材料，以减少热辐射。
The multi-layer insulation is composed of aluminum foils of high reflectivity as the reflecting screen, and insulation material with low heat conductivity and low gas-passing speed to reduce heat radiation.

4. 容器外壳与内胆间的夹层为高真空状态，以防止气体的热对流，并采用在低温状态下吸附量大的吸附剂，以保证容器的性能长期稳定可靠，产品寿命不低于5年。
The jacket between the outer shell and inner tank is of high vacuum to prevent thermal convection. Moreover, the adsorbent with high adsorbing capacity at the cryogenic temperature is used to ensure the long-term stable and reliable performance of the dewar, with more than five-year life.
 
5. 航空运输型液氮生物容器中先进的液氮吸收体，可大量吸附液氮并防水、防潮。当向容器中注入液氮时，液氮吸收体便充分吸附液氮，通过液氮吸收体吸附的液氮自然挥发形成氮气，使内胆中的温度在一定时期内始终保持在–150 ℃以下，保存的生物样品便可在冷冻和干爽状态下储存或安全地进行远距离运输，即使在运输途中容器倾倒，也不会有液氮流出。
 
The transport liquid nitrogen containers use advanced liquid nitrogen adsorber to adsorb liquid nitrogen greatly, which it can be waterproof and moistureproof. While filling liquid nitrogen, liquid nitrogen adsorber can adsorb liquid nitrogen in bulk and can this liquid nitrogen can evaporate and become nitrogen, thus the temperature of inner tank can be kept under -150℃ for a certain period. The biological specimen can be stored and transported for long-distance in dry and clean condition. Even if the container is turned over, liquid nitrogen never spills out.
