The invention provides a quick thermal response composite phase change heat reservoir and a preparation method thereof, and can solve the problems of long thermal response time and low heat dissipating efficiency of a phase change heat reservoir prepared by single phase change paraffin. The quick thermal response composite phase change heat reservoir is realized through the following methods: forward and reverse continuous U-shaped heat dissipating groove cavities serially connected in a linear array sequence are formed in an inner cavity of a heat storage container; the forward U-shaped heat dissipating cavity serves as a paraffin cavity filled with phase change paraffin (4); the reverse U-shaped heat dissipating cavity serves as an alloy cavity filled with a phase change alloy (5); the high-heat-conductivity phase change alloy and the high-enthalpy-value phase change paraffin are sealed as a whole through sealing of upper and lower sealing cover plates (2); and a phase change paraffin and phase change alloy filling port of the heat reservoir is further welded through laser to realize preparation of the quick thermal response composite phase change heat reservoir. The high-efficiency heat transfer of the phase change heat reservoir is realized by the combined effect of the high-heat-conductivity phase change alloy with the heat conducting coefficient of being not less than 15 W / (m. K) and the high-heat-conductivity aluminum alloy of the phase change heat reservoir.
