A heat pipe allows for rapid heat transfer. The heat pipe itself is a copper tube that maintains a vacuum and contains a small amount of liquid.
The low pressure (vacuum) in the copper pipes means that the liquid boils at a low temperature (about 30oC / 86oF), turning to steam and rushing up to the heat of the heat pipe, carrying heat. It dumps the heat (to the glycol solution running through the header), condenses and runs back down to repeat the process.
The Hanania Investment heat pipes are made from Oxygen free copper of a very high purity, which is important to ensure the long term longevity of the heat pipe.
Normal water pipe copper (as used for the header) is not suitable for the heat pipe because over time oxygen and other trace element leach out, forming an air pocket in the top of the heat pipe.
The header is made from copper which makes for excellent heat transfer and is corrosion resistant and allows all connections to be brazed rather than soldered.
It uses “dry” plug-in heat pipes meaning that the connections are plug-and-play which makes installation or replacement very simple.
By comparison, other evacuated tube systems that require the manifold be opened for installation or replacement which is time consuming and can cause burns to the installers hands on a sunny day.
The manifold uses a powder-coated all-aluminum casing for durability, structural integrity and light weight.
The light weight is important for ease of installation and to reduce total roof loading in larger installations that can in some cases include up to 150 collectors.
The manifold is packed with glass wool insulation and is sealed with special UV stabilized silicone rubber that can withstand temperatures of up to 482 degrees F.
Heatpipe solar systems are widely used to heat water for boilers to lower fuel consumption for heating homes or commercial building or even industrial facilities
