The copper heat pipe is composed of a shell, a suction core and an end cover. 1.3× (10-1 ~ 10-4) Pa negative pressure is pumped into the pipe and then appropriate amount of working liquid is filled. The capillary porous material of the suction core close to the inner wall of the pipe is filled with liquid and then sealed. One end of the tube is the evaporation section (heating section), the other end is the condensation section (cooling section), according to the application needs in the middle of the two sections can be arranged adiabatic section. (See the schematic diagram below)

Copper heat pipe is a heat transfer element that relies on its own internal working liquid phase transformation to realize heat transfer. It has extraordinary thermal activity and thermal sensitivity. It absorbs when it is hot and releases when it is cold.

2. Basic features

1 Super thermal conductivity: fast heat conduction, high strength, high efficiency, heat conduction speed can reach the speed of sound.

2. Good isothermal property: Good isothermal property enables copper heat pipe to transfer large heat flux and small heat transfer resistance under small temperature difference.

3 Heat flux variability: Copper heat pipe can independently change the heating area of the evaporation section or cooling section, that is, heat is input with a smaller heating area and output with a larger cooling area, or copper heat pipe can input heat with a larger heat transfer area and output heat with a smaller cooling area.

Working principle and characteristic sharing of copper heat pipe

Safety and reliability: there is no overpressure in the tube, not afraid of dry burning. After vaporization of liquid working medium, the internal pressure of copper heat pipe does not change with the change of temperature.

5 Environmental adaptability: not limited by the environment, copper heat pipe can be independently designed according to the needs of the environment.

6 Wide application field. Superconducting copper heat pipe shape has greater flexibility, a wider range of applications, can adapt to a variety of harsh working environment.

Copper heat pipe is the main heat conduction element of waste heat recovery device, which is fundamentally different from ordinary heat exchangers. The heat transfer efficiency of copper heat pipe waste heat recovery device can reach more than 98%, which is incomparable to the ordinary heat exchanger.

Performance characteristics of copper heat pipe waste heat recovery device:

1. High safety and reliability:

Conventional heat exchange equipment is generally inter-wall heat transfer, and hot and cold fluids flow through on both sides of the wall, such as leakage of the pipe wall or the wall, it will cause production loss. The waste heat recovery device of copper heat pipe is the secondary interwall heat transfer, that is, the heat flow can be transmitted to the cold fluid through the evaporating section of the copper heat pipe wall and the condensing section of the tube wall.

2. Copper heat pipe waste heat recovery device has high heat transfer efficiency and remarkable energy-saving effect.

3, copper heat pipe waste heat recovery equipment has good corrosion resistance

The wall temperature of copper heat pipe can be adjusted, and the temperature of copper heat pipe wall can be adjusted above the dew point of low temperature fluid by proper heat flow transformation, so as to prevent dew point corrosion and ensure the long-term operation of the equipment. Due to avoiding the dew point of the flue gas, the dust is not easy to stick to the fin and pipe wall. At the same time, the copper heat pipe will generate self-vibration when conducting heat, so that the ash is not easy to adhere to the tube wall and fin, so that the ash will not be blocked.

4. Flexible installation and structure layout:

The installation of copper heat pipe waste heat recovery device does not need to change the original process system, the structure design and position arrangement is very flexible, can adapt to various complex occasions.
