Construction
A heat pipe typically consists of a sealed tube made of a thermally conductive material like copper or aluminum. Inside the tube is a working fluid, which can vary depending on the application (e.g., water, ammonia, or specialized liquids for low or high-temperature applications).
Construction
Inside the pipe, there’s also a wicking material that lines the inner walls. This material helps in the distribution of the working fluid through capillary action.
Phase Change Process
- Evaporation: When heat is applied to one end of the heat pipe (the evaporator section), the working fluid absorbs this heat and evaporates, turning into a vapor.
- Condensation: The vapor then moves to the cooler end of the pipe (the condenser section), where it releases the absorbed heat and condenses back into a liquid.
- Return to Evaporator: The liquid is drawn back to the evaporator end by the capillary action of the wick, where the cycle repeats.
SOLAR HEATING WITH HEAT PUMP
Solar heating with a heat pump is a hybrid heating system that combines the benefits of both solar thermal technology and a heat pump. This type of system is designed to provide space heating, hot water, or both for residential or commercial buildings.
Renewable Energy Integration: Combining solar thermal energy with a heat pump allows for a more consistent and efficient heating process.
Increased Efficiency: The heat pump enhances the overall efficiency of the system by extracting additional heat from the surroundings, even during periods of limited sunlight.
Year-Round Operation: The system can operate year-round, utilizing both solar energy and heat pump technology to provide heating even in less sunny or colder conditions.
Reduced Energy Costs: By using solar energy and a heat pump, the system can potentially reduce reliance on traditional energy sources, leading to lower energy bills.

Sunowner's commitment to the energy transition
Our mission at Sunowner is to reduce the carbon emissions and environmental impact of our buildings with high-performance, durable solar panels.
To achieve that mission, Sunowner is guided by 3 core values:
- To continuously innovate in the ecodesign of our Heat Pipe Technology: by developing manufacturing solutions that reduce carbon emission and environmental impact
- To actively contribute to the development of the industry: by offering heat pipe training programs, participating in solar lobby efforts and especially through building a network of local and reliable installers
- To present a unique and unmatched experience for our customers: by guiding our customers from A to Z in their solar projects from simulation to installation and beyond.
Heat pipes are thermal transfer devices capable of transferring heat and energy several hundred times faster than conventional methods. A traditional heat pipe is a hollow cylinder filled with a vaporizable liquid.
How do Heat Pipes Work?
- Heat is absorbed in the evaporating section
- Fluid boils to vapor phase
- Heat is released from the upper part of cylinder to the environment; vapor condenses to liquid phase
- Liquid returns by gravity to the lower part of cylinder (evaporating section)
This process is used to improve dehumidification and recover energy from exhaust air streams in air conditioning as described below.
Using Heat Pipes to Improve 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 moisture removal. The “over cooled” air is then reheated to a desirable 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 considerably more moisture than regular systems.
Using Heat Pipes to Recover Energy from Exhaust to Supply Air
State of the art heat exchangers now allow for either equal calls for cool and heat recovery or optimizing thermal recovery in the season that matters most, while still allowing for appreciable recovery in the other season. Compact design, low pressure drop, high optimized season effectiveness and trouble-free operation with no moving parts, makes this product ideal for design engineers and owners alike.
Moreover, to reduce or eliminate the likelihood of any contamination of supply air, a foam-filled separation of up to 40″ can be incorporated into the design. Or, a split passive system with up to 60’ of separation between air streams.
