现在做工矿灯有使用散热器里面加个铜棒，铜棒里面加入液体并抽真空，这个技术叫做heat pipe ,即热管技术，附件为其基本原理，请参阅(里面是中文的）
What Are Heat Pipes?

Heat Pipe Structure

A traditional heat pipe is a hollow cylinder filled with a vaporizable liquid.

A. Heat is absorbed in the evaporating section.
B. Fluid boils to vapor phase.
C. Heat is released from the upper part of cylinder to the environment; vapor condenses to liquid phase.

D. Liquid returns by gravity to the lower part of cylinder (evaporating section).

Heat Pipes for Dehumidification

Heat pipes may be described as having two sections:

precool

and

reheat

. The first section is located in the incoming air stream. When warm air passes over the heat pipes, the refrigerant vaporizes, carrying heat to the second section of heat pipes, placed downstream. Because some heat has been removed from the air before encountering the evaporator coil, the incoming air stream section is called the precool heat pipe.Air passing through the evaporator coil is assisted to a lower temperature, resulting in greater condensate removal. The "overcooled" air is then reheated to a comfortable temperature by the reheat heat pipe section, using the heat transferred from the precool heat pipe. This entire process of precool and reheat is accomplished with no additional energy use. The result is an air conditioning system with the ability to remove 50 to 100% more moisture than regular systems.
