If the environment where the device is located experiences extreme temperatures, the pipes may crack due to thermal expansion and contraction. In such cases, an external water pump 5 can be connected through the first connector 3 and the second connector 9. Heat-absorbing liquid is then added to the distribution pipe 1 and the heat exchange pipe 2. In high-temperature environments, the dispersion shell 7 can be placed in a ventilated area to quickly lower its internal temperature. In low-temperature environments, the dispersion shell 7 can be immersed in hot water to quickly raise its internal temperature. Then, the external power supply to the water pump 5 is turned on. Once powered on, the water pump 5 will carry liquid of appropriate temperature. First, inside the distribution pipe 1, it flows through the first connector 3, through the first connecting pipe 4, and then pressurized by the water pump 5. Afterward, it enters the dispersion shell 7 through the second connecting pipe 6.

The heat exchange pipe 2 and the first connector 3 are made of copper, which has an extremely high thermal conductivity and can quickly and effectively conduct heat. The reinforcing layer 10 is made of polyester fiber, which can significantly improve the bending and pressure resistance of the pipe. The inner layer 11 is made of polyethylene, which has extremely low water absorption. Water molecules have difficulty penetrating into the interior of the polyethylene material, so that the PE pipe will not experience performance degradation due to water absorption when used in humid environments or in water.
