Doomsday Bunker Upgrade

There is actually not much that can be modified in the structural improvement. First of all, the tent itself has to be in contact with the air. In addition, it is a soft material tent. It is impossible to say that a tent is made between the outer and inner cloth of the tent. Vacuum sandwich, or fill some hard high-performance insulation materials to make an insulation layer.

The traditional double-layer design is already a very reasonable structure. Even in the research expeditions of Mount Everest and the north and south poles, this double-layer structure tent is sufficient.

What Chen Xin can do is to add an inflatable insulation layer at the bottom of the tent to insulate heat from dissipating to the ground, and at the same time add a small porch with two layers of curtains at the door, so that when someone opens the curtain, the outside will not be cold. Air enters the tent directly, blocking the heat loss inside.

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

In addition, there are improvements in materials.

Because of the cost issue, the material used in this large tent is PVC airtight cloth, and the PVC material has been said before, its temperature resistance is -40℃~65℃, beyond this range, the material properties will change. Lose the original performance.

In the case of small tents, manufacturers can use better materials such as PU and PE as the coating of the tarp because they do not have to worry about the cost too much, so that the tent has better protective performance.

However, PU material, or polyurethane, is currently the best thermal insulation material in the world. The thermal insulation material used by Chen Xin and his friends in the living group was polyurethane coating when they built the shelter.

According to the different material formulations, this material can be used to withstand -50℃~150℃. Among them, TPEE thermoplastic polyester elastomer, also called polyester rubber, has excellent performance and can withstand temperature differences of -70℃~ Between 200°C, it can be said to be an excellent insulation material now.

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 high-performance insulation material is also urgently needed for the country. Although there is a lot of output, it is not in the market. There is not much inventory.

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

The captain was still very dedicated to the renovation of the tent, and helped Chen Xin find a staff member from the city to coordinate the issue of the materials he needed.

PU material, a high-performance thermal insulation material, is naturally a good steel to use on the blade, and it is unlikely to be evened out for Chen Xin to improve the tent.

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

"Cold-proof felt? Can this be used? How much can I get?" Chen Xin heard the staff say that there is only cold-proof felt. Although it feels far from the material he wants, since the supplies are tight, then It can only be of any use.

Seeing that Chen Xin did not dislike the cold-proof felt, the staff hurriedly said: "This was used for the construction of greenhouses before the disaster in the city. However, after a meteorite hit, the greenhouses were not built. Many cold-proof felts were ordered at that time. The backlog has accumulated. If you need it, I can ask someone to get you a batch."

"That's all right, let's get a few rolls over. It can start the heat preservation effect as much as possible on the tent." Chen Xin could only say so at this time.

When the staff went to arrange for someone to deliver the cold-proof felt, Chen Xin was not idle either. He returned to the tent already set up, ready to see what could be improved.

In the tent, five volunteers assigned to him are gathering in front of a stove and burning on fire.

They don’t have protective clothing like Chen Xin and the members of the rescue team. They only have ordinary cold-proof clothing. They are sitting in front of the stove, roasting their shoes wet with snow, which inevitably makes the tent smell a bit like Unpleasant.

Although Chen Xin was wearing power armor and had an air filter system that could not smell, he could still imagine what it smelled like.

This obviously reminded him that in addition to improving heat preservation performance, the tent can also improve the heater so that the heater can provide more heat.

This is obviously Chen Xin's old line, and he still has a handy tool like a universal manipulator, and the renovation of the heater does not even require a system upgrade.

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

Although this set of power armor is not as exaggerated as a sci-fi work that weighs one or two tons at every turn, it still has a few hundred kilograms, so it is difficult for Chen Xin to sit on the temporary bed next to it~www.ltnovel.com~ for fear of being crushed directly. , Can only sit on the ground.

Fortunately, flexibility was considered when designing the joints, and sitting on the ground is not a problem.

Using the robotic arm to disassemble the heater, and at the same time using the scanning device on the robotic arm to scan the heater as a whole, Chen Xin disassembled the heater while looking at the scan results projected on the helmet screen, thinking about how to make improvements.

There are a total of four heaters in the tent. For safety reasons, they are all electric heaters. They are powered by an external power source. As for the power source, the isotope temperature difference battery on the new car yesterday.

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

Therefore, without worrying about power consumption, the simplest and rude way to reform the heater is to directly increase the power. Although the Lida flying brick is a wasteful approach, it has to be said that many times things can be solved in this way. .

Considering that the isotope thermoelectric battery can output stable power for ten years, Lida flying brick type amplifying power is actually the simplest choice at the moment.

Chen Xin chose this method only after a little consideration.

However, 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 robot arm to continue dismantling the heater, Chen Xin decided to try this time without upgrading the system to complete the transformation of the heater. At any rate, he has a top tool like a universal robot arm. Chen Xin doesn't think he is even a heater. Not sure.

However, after he dismantled the heater into a piece of parts, Chen Xin discovered a fact that made him a little embarrassed.

That is, if there is no raw material, even if he has a universal robot 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.
