For it’s different physical property of each kind of ingredient inside of the many compound working substances of "Onergy energy" has caused to application of the scope of the compound working substance heat transfer which is suitable foe the heat transfer utilization under -40 ℃ ~ 1,500 ℃ operating temperature environment .
The heat transfer part is a vacuum state of airtight after sets into the above heat transfer working substance and make seal .
The ultra heat transfer working substance improved the ordinary heat-transfer capability, may cause the heat energy nearly without thermal resistance transmission, and increased the heat transfer efficiency , may cause the heat transfer efficiency to be bigger than 1.
The working medium explanation : -40 ℃ ~ 300 ℃
The method of heat transformation explanation: The heat transfer working substance has changed , it will carry on natural circulation under it’s own gravity function .
The applicable scope: It is suitable to the warmth of the original part wall-40 ℃ ~ 350 ℃
Axial heat flow density: >= 30MW/m2
Radial direction heat flow density: >= 150kW/m2
Heat transfer efficiency: 95% ~ 98%
Equivalent thermal conductivity: >= 15MW/m ℃
Part life expectancy : 130000h
Spatially exposes to the sun performance: Any natural luminous intensity cannot affect the performance of heat pipe .
Equipollence heat performance: The thermal resistance is small, equipollence heat capability performance good . Temperature difference between evaporation section and the condensation section is smaller than 5 ℃.
Compatibility: The heat transfer working substance is heterogeneity compound , it can effectively suppress the production of hydrogen and oxygen , and it cannot have the chemical and electrochemistry reflection with the shell material , the accommodating performance is good.
Security: The selection of shell material and thickness should be match with the pressure of heat transfer working substance when it is working the cavity pressure is low , it cannot occur the high temperature cartridge igniter, safe and reliable .
The main performance index of heterogeneity compound working substance heat pipe
Axial heat flow density >= 28MW/m
Equivalent thermal conductivity >= 14MW/m ℃
the total emission quantity activity 1.4 *10-1Bq/g
R
adioactive activity b is 1.7 * 10-1Bq/g
Effective service life >= 150000h
component use way: Gravity, non- gravity
component structural style: The tubular, the tubular compress, the tubular knee bend, plate-type, the tube - tube combination, the board – board combination , the tube - board combination .
The scope of warth : Low temperature part - -60 ℃ to 80 ℃, medium warm part - 30 ℃ to 300 ℃, high temperature part - 300 ℃ to 1,100℃
The suitable material quality: The non-ferrous metal, the ferrous metal and each kind of nonmetal that may meet the requirements.
