Chapter 86 Speedy Cobra VS Spider King (3)
The two cars were locked in a stalemate and quickly ran through half a circle. However, the attack of the air knife only scraped off a little bit of Speedy Cobra. Apart from the paint on his body, there is nothing else.
Okita Kai increased the power of the air knife bit by bit, but the speedy cobra was like a hard shield, making it impossible for him to attack.
"The Speedy Cobra is made of carbon fiber and aluminum alloy, materials only used in F1 racing cars. Don't even think of damaging it with your attacks," Fujiyoshi said.
“Is it this kind of hard material again?” Hearing this, Okita Kai turned back and glanced at Lin De, who was watching the battle. “So, what about the wind wing of this car that is used for cornering? That kind of wind wing. I’m afraid the precision joints can’t guarantee the same high strength as the entire body. As long as they are cut off, this car without guide wheels will fly off the track on its own.”
"Kill him, Spider King!" Okita Kai roared. The Spider King on the track slowed down by half his body and aimed the air knife at the wind wing of the fast cobra.
However, Fujiyoshi smiled when he saw this scene.
Zi~ After a harsh friction sound, the painting on the right wing of the Speedy Cobra that was attacked by the Spider King fell off, revealing the crystal diamond inner core. No matter how hard the Spider King tried, this diamond wind The wings are just intact.
"What? What is this?" Okitaumi asked in surprise.
"It is diamond, the hardest thing in nature. Although your air knife is sharp, there is nothing you can do in front of it." Fujiyoshi said with a proud smile.
At this moment, the Spider King, who had maintained the highest power of the Air Knife for a long time, had an obvious lack of power, and his speed instantly stagnated, while the Speedy Cobra took the opportunity to throw away the Spider King again.
Seeing this scene, Lin De also nodded secretly: "Sure enough, this thing can't maintain the highest power attack mode for a long time."
"Oops! The Spider King is fighting against the speeding cobra. Why did the speed suddenly slow down after launching consecutive attacks without success? "The four-wheel drive fighter said, "If this happens, it will be difficult to catch up with the speeding Cobra that has already accelerated in the remaining ten laps!"
Seeing this, Okitaumi had no choice but to adjust the power of the air knife so that it could still function as a wind breaker without consuming too much battery power.
After the adjustment, the Spider King began to accelerate again, but it was unable to catch up to the fast Cobra that had already accelerated.
The Speedy Cobra completed the 50-lap race first and won this duel.
Tengyoshi stopped the Speeding Cobra with a smile, but the moment the car took over, his expression changed slightly.
"I won. According to the agreement, you are not allowed to set foot here in the future." Fujiyoshi raised his head and said, but Lin Bo and J noticed that this guy seemed to be enduring something.
"Hmph, you're pretty awesome." Okitami snorted coldly and stopped the Spider King with a mechanical arm. "But don't think that today is the full strength of the Spider King. Let's meet again in the summer game. ."
"I will also win in the summer competition!" Fujiyoshi said.
"Hahaha, let's wait and see." Okita Kai turned around and disappeared into Fujiyoshi Paradise in a few flashes.
"Fuji! Your new car is so awesome!" Xiao Hao was the first to rush forward excitedly and congratulate Fujiki.
"Hey, that's natural." Fujiyoshi said proudly. "Hey, let me tell you, that guy has left. There is no need to hold it in any longer." Lin Tie noticed that the palm of Tokichi's hand holding the Speedy Cobra was slightly red from the heat, so he reminded him aloud.
"Hot, hot, hot, hot!" Fujiyoshi couldn't hold himself any longer. He placed the Speedy Cobra on the platform aside and started to wave away, "Yanzuo! Ice cubes! Hurry up! ! ”
Yanzuo hurriedly brought ice water and scalding ointment, while Lin Yu reached out and touched the fast cobra that Fujiyoshi placed on the platform.
Although it has been stopped for a while and was cooled down once by Fujiyoshi's hand, the surface temperature of the fast Cobra this time has also exceeded 50 degrees. I am afraid that the temperature at the front of the car where the motor compartment is located is probably Even higher.
“How could this be? Logically speaking, it wouldn’t be so hot. The coil is made of silver with lower resistance. With the same performance, the power consumption and heating problems should be smaller than those of copper coil motors. That's right." Lin De hesitated, "Not to mention that you added a water cooling system, and the airflow from the air vent in front of the car will also blow through the motor compartment."
"Mind if I take it apart and take a look. "?" Lin Tie asked.
"Come on." Fujiyoshi said while bandaging.
After Lin De disassembled the Speedy Cobra, he looked at the motor cover that had been slightly deformed under the high temperature. "The thermal conductivity of aluminum alloy with this composition is still too poor, and the water cooling effect in such a small space is very poor." It is indeed limited. This is still when using silver coils. If it is a copper coil with higher resistance, the motor housing should have melted."
Lin De removed the motor housing and then removed it. The motor was separated, and the plastic motor back cover had been deformed under high temperatures.
"This..." Xiaolie frowned upon seeing this, "The performance of this motor is too outrageous."
"What do you think is the solution? If the distance of the runway is any longer today, If it's longer, your car may not be able to hold on." Lin Tie looked at Fujiyoshi and asked, "Should we sacrifice the performance of the motor a little or think of another way?"
"This..." Fujiyoshi also fell into thinking. After a while, Fujiyoshi raised his head and looked at everyone: "What can you do?"
"Let's change the chassis. Since the Speedy Cobra has abandoned the design of the spring guide wheel of the Speedy Axe, it doesn't need an aluminum alloy chassis to absorb kinetic energy. Changing to a material that dissipates heat faster may help." Lin Said.
“I think this water-cooled heat dissipation device can be dismantled. The space in the car is still too small. The effect of such a small water-cooling device is extremely limited. Save space and expand the size of the air duct. The cooling effect may be better with air cooling," J also suggested.
"This is the only way." Fujiyoshi nodded.
"Fuji, hurry up and adjust the car, let's compete!" At this time, Xiao Hao took out the Victory Charge from his arms. After the game just now, Xiao Hao felt a little itchy. .
"Xiao Hao! We have to go home and do our homework. We promised mom that we would only come out for one morning!" Xiao Lie directly held down Xiao Hao, who was about to fight Fujiyoshi for three hundred rounds.
"That's really a pity. After the exam is over next week, let's meet again at my institute." Lin Ye shrugged.
"Ah ah! I don't want to do my homework!" Xiao Hao struggled hard while being dragged out by Xiao Lie.
