Heat Pipes are one of the most efficient ways to move heat, or thermal energy, from one point to another. These two-phase systems are typically used to cool areas or materials, even in outer space. Heat pipes were first developed for use by Los Alamos National Laboratory to supply heat to and remove waste heat from energy conversion systems.
Heat Pipes are used to transfer heat with minimal temperature difference from the heat source (evaporator) to the heat sink (condenser) as well as to spread the heat across a surface. Many factors have to be considered in choosing a heat pipe for a specific application.
A heat pipe is a heat-transfer device that combines the principles of both thermal conductivity and phase transition to effectively transfer heat between two solid interfaces. At the hot interface of a heat pipe a liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. The vapor then travels along the heat pipe to the cold interface and condenses back into a liquid releasing the latent heat. The liquid then returns to the hot , heating pipes heat pipe
Energy recovery heat pipes from Heat Pipe Technology (HPT) provide economical and reliable recovery of both heating and cooling. This means that the payback time of your investment is minimal. HPT heat pipes are economical because of their low initial cost and minimum maintenance requirement.
The Heat-pipes are installed into manifolds and transfer heat from the heat source to the cooling water. The baffle plates direct water along the Heat-pipe cooling length to give an increased cooling area contact.
Omni Resort is a premier golf, leisure and meeting retreats installs HPTs dehumidifier heat pipes on all of its outside air units saving $400,000 annually in A/C energy costs.
The installation process of a pipe heating cable is relatively simple. After wrapping your pipes with heat tape, add extra stability by securing the cable with cable application tape that's rated for varying temperatures so it won't lose its adhesive properties. Then, cover the entire pipe with heavy-duty heat wrap for pipes.
Hot water heating pipes that distribute heat through a building often make creaking or even clanking sounds at the start and again at the end of a heating cycle. These sounds are usually due to expansion of the piping and movements as the piping shifts, especially where it passes through an opening in building framing, floors, or walls.
This program will give a performance curve of a copper-water heat pipe with the given input values. This curve is a guide to help estimate heat transport capacity for ACTs copper-water heat pipes using common wick structures.
These are our 3 Steps on How To Stop Your Heating Pipes Making Noise. Lift your floorboard (always be careful because of the pipes and cables that are underneath them) Everywhere a pipe touches a joist or another pipe, just squash some felt around it.
Pipe Heating Cable (Constant Wattage) Wrap-On Pipe Heating Cable. Prevents frozen water pipes to 50F. Simply wrap on, insulate and plug in. For use on metal and rigid plastic pipes. A built-in thermostat turns the cable on at 38F. Proven low-wattage design uses up to 70 percent less energy than other cables.

The cable can be doubled back on the side opposite if needed. On a small pipe in tight quarters all this cable is somewhat cumbersome. What I was really looking for was a low-cost heating element that I could position on or near the pipes that would constantly heat to a set temperature or with a variable temperature control.
The EASY HEAT IN-LINE HEATER provides economical, effective in-pipe freeze protection for water supply lines. The cable consists of dual conductor resistance wire with P.V.C. insulation, continuous ground braid, and clear food grade outer P.V.C. jacket.
Isobar Heat Pipes (sometimes called heat tubes) are super-thermal conductors that have the capacity to transfer large amounts of energy at high speeds in both heating and cooling applications. Isobar uses two-phase heat transfer technology that are able to move thermal energy up to 250+ times faster than standard copper material.
I recently had some baseboard heat pipes replaced in my house during a renovation. The baseboard system was previously all copper pipes. In the renovation the contractor used pex pipe for the return lines in place of copper. The baseboard heat elements (with fins ) is still copper. The returns run under the heating elements.
Heat-Line provides electrical heat tracing and heating cable solutions that are fully certified and suitable for installation in multiple freeze protection applications including new/ existing residential water supply pipes, new/ existing municipal water supply pipes, sump pump lines, drilled/ dug wells, small/ large diameter drain pipes, sewage/ septic pipes and drains, small/ large diameter culverts, metal/ non-metal tanks and vessels, and roof de-icing.
Cryogenic heat pipes operate between 4 to 200 K. Typical working fluids include helium, argon, oxygen, and krypton. The amount of heat that can be transferred for cryogenic heat pipes is quite low due to the small heats of vaporization, high viscosities, and small surface tensions of the working fluids.

A heat pipe is a thermal transfer device. Its basically a sealed tube filled with refrigerant. It typically spans the supply air and exhaust air sides of a system. . Energy is transferred with no moving parts from one air stream to the other (as long as there is a temperature difference
Standard Heat Pipes A heat pipe is an extremely efficient thermal conductor. It can transfer large quantities of heat over a long distance essentially at a constant temperature.
1. Raise the temperature on the thermostat to activate the heating boiler. As hot water flows through heating system, listen for creaking, popping sounds. 2. Inspect the hot-water pipes leading from boiler. Check to be sure there's sufficient expansion space where the pipes pass through holes in walls and ceilings. 3.
The most common heat pipe working fluid is water for an operating temperature range from 1C to 325C. Low temperature heat pipes use fluids such as ammonia and nitrogen. High temperature heat pipes utilize cesium, potassium, NaK and sodium (8731,473K).
The heat pipe is a sealed system containing a liquid, which when vaporized transfers heat under isothermal conditions. The temperature of the vapor corresponds to the vapor pressure, and any temperature variation throughout the system is related directly to vapor pressure drop.
Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels using heat tracing cables.Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe.
Retro-Line is an advanced, self-regulating heat trace system that is used for safe, efficient and reliable internal pipe freeze protection. Retro-Line is designed to provide internal freeze protection for new or existing, water supply pipes and sump pump line systems without the need to excavate.
There, it releases its heat into the air stream and returns to its liquid state again. Gravity then causes the refrigerant to flow to the evaporator end of the pipe to begin the cycle again. Most models of heat pumps and central air conditioners can be retrofitted with dehumidifying heat pipes.
