Definitions
- Heat transfer fluids sometimes referred to as heat transfer media, are heat transfer agents
- diphenyl oxide sometimes referred to as diphenyl ether
- the present invention is a mixture in broad proportions of diphenyl oxide (DPO), which
- impurities and/or isomers can be added in small quantities to this preferred heat transfer mixture
- diphenyl methane can be substituted for the pure 1,1 diphenyl ethane material of the preferred
- the XCELTHERM XT product is processed by the assignee of
- isomers can be substituted for the pure 1,1 diphenyl ethane of the preferred composition.
- Liquid phase fluids-characterized by low vapor pressure with heat transfer occurring in the liquid phase 1.
- Heat transfer coefficient the ability to upload, transfer, and download heat/unit time-area at a given temperature.
- a major factor in a fluid's use is its environmental impact - whether it is regulated as a hazardous
- the objective is to provide a single fluid that will operate in either the liquid/vapor phase with
- the heat transfer coefficient is a primary measure of the ability of a heat transfer medium
- Table 1 represents a comparison of the heat transfer coefficients of the common types of
- Table 2 represents a comparison of the heat transfer coefficients of the common types of
- (-)% shows the percentage decrease in heat transfer coefficient of DPO/DPE-DPE/DPO relative to the indicated product.
- Thermal stability may be defined as the resistance of chemical bonds to thermal cracking. A fluid exhibiting greater thermal stability relative to another at any given temperature will
