Doomsday Bunker Upgrade

In fact, there are not many places that can be modified in terms of structural improvement. First of all, the tent itself needs to be in contact with the air. In addition, this is a tent made of soft material. It is impossible to say that it is impossible to create a tent between the outer cloth and the inner cloth Vacuum interlayer, or fill with some hard high-performance insulation material to make an insulation layer.

The traditional double-layer design is already a very reasonable structure. Even in the Everest and the North and South Pole scientific research, this double-layer tent is sufficient.

All Chen Xin can do is to add an inflatable insulation layer at the bottom of the tent to prevent 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, it will not let the outside cold. The air enters directly inside the tent, 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 thermal insulation effect.

In addition, it is the improvement of materials.

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

For small tents, manufacturers can use materials with better performance such as PU and PE as the coating of the tarpaulin because they can not worry too much about the cost, so that the tent has better protection performance.

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

According to different material formulations, this material can obtain materials that can withstand -50℃~150℃. Among them, TPEE thermoplastic polyester elastomer, also called polyester rubber, has excellent performance and can withstand temperature difference between -70℃~ Between 200 ℃, it can be said that it is an excellent thermal 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 thermal insulation material is also an urgently needed material for the country. Not much in stock.

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

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

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

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

"Cold-proof felt? This can be used as well, so how much can you get for me?" Chen Xin heard from the staff that there was only cold-proof felt. Although he felt that it was far from the material he wanted, since the supplies were tight, then It can only be used for anything.

Seeing that Chen Xin didn't dislike the cold-proof felt, the staff hurriedly said: "This was used to build a greenhouse before the disaster in the city, but after a meteorite hit, the greenhouse was not built, and there were many cold-proof felts ordered at that time. The backlog is down. If you need it, I can have someone get you a batch."

"Okay, let's get a few rolls first. Covering it on the tent can also start the thermal insulation effect." Chen Xin can only say that at this time.

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

In the tent, five volunteers who were assigned to him were roasting in front of a fireplace.

They don't have protective clothing like Chen Xin and the members of the rescue team. They only have ordinary cold-proof clothing on their bodies. At this time, they are sitting in front of the heater, baking their snow-wet shoes, which inevitably makes the tent smell a little bit. Bad smell.

Although Chen Xin was wearing power armor and had an air filtration system and 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, it can also improve the stove, so that the stove can provide more heat.

This is obviously Chen Xin's old line of work, and he still has a useful tool like a universal robotic arm, and he doesn't even need a system upgrade for the renovation of the heater.

Holding 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 power armor is not as exaggerated as one or two tons in sci-fi works, it still has a few hundred pounds, so Chen Xin is not good to sit on the temporary hospital bed next to him. He can only sit on the ground because he is afraid of being directly crushed. .

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

Using the robotic arm to disassemble the heater, and using the scanning device on the robotic arm to scan the heater as a whole, Chen Xin dismantled the heater while looking at the scan results projected on the helmet screen, thinking about how to transform it.

There are a total of four heaters in the tent. Considering the issue of safety, they are all electric heaters, which are powered by an external power supply.

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

Therefore, on the premise of not worrying about electricity consumption, the simplest and most rude way to transform the heater is to directly increase the power. Although it is a wasteful practice to fly bricks, I have to say that things can be solved in this way in many cases. .

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

Chen Xin chose this method with just 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 robotic arm to continue dismantling the heater, Chen Xin decided to try to complete the renovation of the heater without a system upgrade this time. Anyway, with a top-level tool like a universal robotic arm, Chen Xin doesn't think he can even have a heater. Can't figure it out.

However, when he disassembled the heater into 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 machining operations, Chen Xin still cannot complete the transformation of the furnace out of thin air.
