    In fact, there is not much that can be modified in terms of structural improvements. First of all, the tent itself has to be in contact with the air. In addition, this is a tent made of soft material. It is impossible to create a gap between the outer fabric and the inner fabric of the tent.  Vacuum sandwich, or fill it with some hard high-performance thermal insulation materials to create a thermal insulation layer.

    The traditional double-layer design is already a very reasonable structure. Even for scientific research on Mount Everest and the North and South Pole, this kind of double-layer tent is enough.

    All Chen Xin could do was add an inflatable insulation layer to the bottom of the tent to prevent heat from escaping to the ground. At the same time, he added a small porch with a two-layer curtain at the door, so that when someone opened the curtain, the cold outside would not be released.  The air directly enters the interior of the tent, blocking internal heat loss.

    For large tents such as medical tents, the tent door and floor are the two main channels for heat loss. As long as the heat loss in these two places is blocked, the tent can achieve better insulation effects.

    In addition, it is the improvement of materials.

    Due to cost issues, the material used in this large tent is PVC airtight cloth. As mentioned before, the PVC material has a temperature resistance of -40c~65c. If it exceeds this range, the material properties will change and the original material will be lost.  Some performance.

    In small tents, because manufacturers don¡¯t have to worry too much about cost, they can use better-performing materials such as pu and pe as the coating of the tarpaulin, so that the tent has better protective properties.

    But among them, PU material, also known as polyurethane, is currently the best insulation material in the world. The insulation material used by Chen Xin and his friends in the survival group when they first built the shelter was polyurethane coating.

    Depending on the material formula, this kind of material can be obtained that can withstand -50c~150c. Among them, Tpee thermoplastic polyester elastomer, also called polyester rubber, has excellent performance and can withstand temperature differences between -70c~200c.  , can be said to be the best thermal insulation material nowadays.

    If possible, Chen Xin would of course want to use this material to upgrade the current medical tents, but it is a pity that this kind of high-performance insulation material is also an urgently needed material for the country. Although there is a lot of output, it is not available in the market.  There isn't much in stock.

    Faced with this situation, Chen Xin could only consider getting some existing materials to make do.

    The captain was quite dedicated to the tent renovation and helped Chen Xin find staff from Linshi to coordinate the materials he needed.

    PU material, a high-performance thermal insulation material, is naturally a good choice for Linshi. Steel is used on the cutting edge, and it is unlikely that it will be released to Chen Xin for use in improving tents.

    However, the staff can still provide Chen Xin with some cold-proof blankets.

    "Cold-proof felt? This can be used, right? How much can you get for me?" Chen Xin heard the staff say that there was only cold-proof felt. Although it felt that it was far from the material he wanted, since supplies were tight, then  It can only be used for whatever it is useful for.

    Seeing that Chen Xin did not dislike the cold-proof blanket, the staff hurriedly said: "This was used to build a greenhouse before the disaster in the city, but then a meteorite hit, so the greenhouse was not built. There were many cold-proof blankets ordered at that time  There's a backlog. If you need it, I can have someone get a batch for you."

    "Okay, let's get a few rolls over first. Covering the tent as much as possible can start the insulation effect." Chen Xin could only say this at this time.

    When the staff went to arrange for someone to deliver the cold-proof blankets, Chen Xin was not idle. He returned to the tent that had been set up, ready to see what else could be improved.

    In the tent, five volunteers assigned to him were gathering around a stove to warm themselves up.

    They don't have protective clothing like Chen Xin and the members of the rescue team. They only have ordinary cold-proof clothes. They are sitting in front of the stove, warming their shoes that are wet from the snow. This inevitably makes the tent smell a bit  Bad smell.

    Although Chen Xin was wearing power armor and had an air filtration system so he couldn't smell it, he could still imagine what it smelled like.

    This obviously reminded him that in addition to improving the thermal insulation performance of the tent, the heater can also be improved so that the heater can provide more heat.

    This is obviously Chen Xin¡¯s old profession, and he now has such a useful tool as the universal robotic arm. The modification of the heater does not even require a system upgrade.

    Bringing an unused heater next to him in front of him, Chen Xin controlled the power armor and sat awkwardly on the ground.

    Although this set of powered armor is not as exaggerated as one or two tons in science fiction works, it still weighs several hundred kilograms., so Chen Xin couldn't sit on the temporary hospital bed next to him because he was afraid it would collapse, so he could only sit on the ground.

    Fortunately, flexibility was taken into consideration when designing the joints, so sitting on the ground is not a problem.

    Using a robotic arm to dismantle the heater, Chen Xin used the scanning equipment on the robotic arm to conduct an overall scan of the heater. While dismantling the heater, Chen Xin looked at the scan results projected on the helmet screen and considered how to modify it.

    There are a total of four heaters in the tent. Considering safety issues, they are all electric heaters and are powered by external power sources. As for the power supply, it is the isotope thermoelectric battery from Chen Xin¡¯s car yesterday.

    With the output power of an isotope thermoelectric battery, it is more than enough to power several tents.

    Therefore, without worrying about electricity consumption, the simplest and crudest way to modify the furnace is to directly increase the power. Although it is a very wasteful approach to force large bricks, it has to be said that many times things can be solved this way.  .

    Considering that the isotope thermoelectric battery can output stable power for ten years, Lida¡¯s flying brick amplification power is actually the easiest choice at the moment.

    Chen Xin chose this method after only a brief consideration.

    But in this case, the circuit of the heater itself needs to be optimized, at least it will not burn out or short-circuit due to too much power.

    Controlling the robotic arm to continue dismantling the heater, Chen Xin decided to try to complete the transformation of the heater without upgrading the system. After all, with such a top-notch tool as the universal robotic arm, Chen Xin didn't think he could even own a heater.  Can't figure it out.

    However, when he dismantled the heater into various parts, Chen Xin discovered a fact that made him a little embarrassed.

    ¡°That is, if there are no raw materials, even if he has a universal robotic arm that can 3D print parts and perform various mechanical processing, Chen Xin still cannot complete the transformation of the heater out of thin air.  (Remember the website address: www.hlnovel.com
