Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 9082.2-1988 "aluminum gravity die without heat pipe."
This standard and GB/T 9082.2-1988 compared to the main changes are as follows.
--- The original standard name "aluminum gravity die without heat pipe" to "have a heat pipe die";
--- Standard scope of the original "aluminum gravity die without heat pipe design, manufacture and testing" to "have a heat pipe and tubular die
There are die plate heat pipe design, manufacture and acceptance ";
--- Kind involving heat pipe made of an aluminum shell and tube heat pipe gravity (working medium. ammonia, acetone, Freon 12, Freon 21, Freon 11,
Freon 113) was adjusted to aluminum and aluminum alloy, copper, carbon steel, stainless steel shell and tube heat pipe (working fluid comprising nitrogen, methane, ammonia,
Hydrofluorocarbon 134A, acetone, water, potassium, sodium and the like);
--- Increased the heat pipe shells, dies, industrial quality requirements, and Appendix given in the form of heat pipe shell, die working fluid combinations;
--- Test project name by heat pipe "Product Qualification Test" and "product acceptance test" to "type test" and "factory inspection";
--- "Type test" contains items than the original standard "product qualification test," adds isothermal performance, reverse gravity heat transfer heat flux, the total thermal resistance;
--- Original standard for heat pipe "life" requirement modifications for the "compatibility" requirement, discrimination on the basis of the "evaporation and condensation heat transfer coefficient
The number of "degree of attenuation modification for the" isothermal performance "and" maximum heat transfer of heat flow "requirements;
--- Increase the environmental conditions of the test and test equipment requirements.
The Standard Appendix A, Appendix B is an informative annex.
The standard proposed by China Aerospace Science and Technology Corporation.
The standard by the China Institute of Aerospace Standardization.
This standard drafting unit. China Academy of Space Technology Master unit, the Institute of Engineering Thermophysics.
The main drafters of this standard. Shaoxing Guo, Miaojian India, Qu Wei.
This standard replaces the standards previously issued as follows.
--- GB/T 9082.2-1988.
