Abstract

The invention discloses an n-octadecane phase change micro-emulsion. The micro-emulsion comprises water and the following components in mass fraction: 5-40% of n-octadecane, 2-20% of surfactant, 0-20% of fatty alcohols and 0-3% of inorganic salts. The preparation method comprises the following steps of: firstly mixing n-octadecane, the surfactant, fatty alcohol and the inorganic salts according to the ratio of the mass fraction, then adding the remained water at 30-40 DEG C, stirring uniformly and standing to obtain the n-octadecane phase change micro-emulsion. The n-octadecane phase change micro-emulsion can be applied to a microelectronic system thermal management, and is used for micro-channel efficient heat dissipation cooling working medium in a thermal management system. The micro-emulsion and the application thereof have the advantages of high latent heat of phase change, wide applicable temperature range, good stability and the like.

Description

technical field

[0001] The invention relates to a microemulsion and its preparation method and application, in particular to a phase change microemulsion and its preparation method and application. Background technique

[0002] The rapid development of microelectronics technology promotes the high integration of various functional modules, the temperature of the chip continues to rise, the heat flux of the chip increases sharply, and the heat dissipation problem caused by it becomes increasingly prominent. Micro-channel heat sink is a new high-efficiency liquid cooling heat dissipation technology, which is gradually being applied in the thermal management technology of large-scale integrated circuits and high-power chips. Heat, so as to achieve cooling effect. At present, the cooling medium used for heat dissipation in microchannels is mainly water. Although water has a larger specific heat compared with general cooling fluids, its thermal conductivity and specific heat cap...
