The utility model discloses a novel
phase change heat storage cavity structure with crosswise arranged heat pipes, which belongs to the technical field of heat storage and comprises a box body, heat exchange pipes and heat pipes, a working cavity used for containing
phase change materials is arranged in the box body, the heat exchange pipes and the heat pipes are arranged in the working cavity, and the heat exchange pipes and the heat pipes are arranged in the working cavity. The
heat pipe comprises a first
pipe section, a second
pipe section corresponding to the first
pipe section and a third pipe section connected between the first pipe section and the second pipe section, the first pipe section is located on one side of the heat exchange pipe, and the second pipe section is located on the other side of the heat exchange pipe. The heat exchange area can be increased, the heat conduction efficiency is improved, the uniformity of the
internal temperature of the
phase change material is improved, and the heat exchange performance is improved; the heat exchange area with the phase-change materials is large, the phase-change materials in all positions in the working cavity are provided with near heat exchange positions, and the heat exchange efficiency of the whole heat storage cavity is high; the problem of uneven temperature distribution in the melting or solidification process of the
phase change material is effectively solved, and the phase change rate is further increased.
