Download Heat Pipe Design and Technology: A Practical Approach by Bahman Zohuri PDF

By Bahman Zohuri

With its targeted skill to move warmth over huge distances with minimum loss, the warmth pipe has emerged as a confirmed environmentally pleasant, energy-saving resolution for passive thermal keep watch over. notwithstanding, till lately, the excessive expense and complicated development use of those incredible mechanisms has often restricted their use to house technology.

Written via a former senior leader scientist at Lockheed who has additionally labored for Westinghouse and the U.S Air strength, Heat Pipe layout and know-how: a pragmatic Approach presents a pragmatic examine of contemporary warmth pipe engineering in nuclear and solar power purposes, discussing the way it could be optimized and made less costly to be used on a much broader scale. An creation to operational and layout ideas, this booklet explores using warmth pipes, relatively in high-heat flux functions and in occasions within which there's any mix of non-uniform warmth loading, constrained airflow over the warmth producing elements, and house or weight constraints. It additionally discusses layout and alertness of self-controlled, variable-conductance warmth pipes for thermal keep watch over in spacecraft.

Offering a evaluation of warmth and mass move thought suitable to functionality, the publication covers matters that could have an effect on winning warmth pipe operation, together with:

  • Balancing of warmth pipe lots
  • Compatibility of materials
  • Operating temperature range
  • Power limitations
  • Thermal resistance
  • Operating orientation

With its presentation of mathematical types to calculate warmth move boundaries and temperature gradient of either excessive- and low-temperature warmth pipes, the publication compares calculated effects with the on hand experimental information from a number of resources to extend self assurance in latest types. It additionally explains the place and the way readers can entry precious interactive laptop codes and a chain of laptop courses built through the writer to aid offered facts, reduction layout, and are expecting performance.

Commercial use of the LHP will begin on the next generation of communications satellites being developed and built by Hughes Space and Communications Company. These satellites take advantage of the passive nature of the LHP, requiring no external means of pumping, along with its ability to 32 Heat Pipe Design and Technology: A Practical Approach transport large quantities of heat over significant distances. This device comes to the heat transfer community at an ideal time, as the aerospace industry is demanding higher and higher power payloads and this increasing power must be handled by the most efficient means possible.

Below the freezing point of water and above about 200 K, ammonia is an excellent working fluid. 999%. A careful analysis of the purity of the ammonia should be obtained from an independent laboratory prior to use. The outer container usually consists of a metal tube to provide mechanical support and pressure containment. The chosen design and processing of the container are extremely important in selecting the metal, because they can affect the useful life of the heat pipe. In addition, a compatibility must exist between the pipe material and the working fluid.

Depending on the wick structure, pipes will operate in environments with as low as À408C. Upper temperature limits depend on the fluid, but 608C–808C is the average limit. 11 HEAT REMOVAL Heat can be removed from the condenser using air cooling in combination with extrusion, bonded-fin heat sinks, or flat-fin stock. Enclosing the condenser in a cooling jacket allows liquid cooling. 12 RELIABILITY Heat pipes have no moving parts and have demonstrated life of over 20 years. The largest contributor to heat pipe reliability comes from control of the manufacturing process.
