The invention relates to the technical field of petroleum and natural gas development, in particular to an immiscible-phase temperature-control phase-change fracturing fluid flow distribution simulation device and method, and the device comprises a phase-change fracturing fluid tank for containing phase-change fracturing fluid; the non-phase-change fracturing fluid tank is used for containing non-phase-change fracturing fluid; the liquid pumping control module is connected with the phase change fracturing fluid tank and the non-phase change fracturing fluid tank; the visual long shaft simulation pipe is connected with the liquid pumping control module; the perforation simulation module is connected with the visual long shaft simulation pipe; and the visual crack simulation flat plate is connected with the perforation simulation module. The device further comprises a liquid outflow control module and an image recording module. By redesigning the structure of the slab crack, the simulation of the perforation se
