The first direction, the second direction and the third direction are respectively an X axis, a Y axis and a Z axis in a space rectangular coordinate system, the Y axis is the length direction of the electronic equipment, the X axis is the width direction of the electronic equipment, and the Z axis is the height direction (thickness direction) of the electronic equipment. I.e. the phase change heat storage modules 21 may be arranged in a horizontal direction or stacked in a vertical direction, or both may be present. The phase-change heat storage modules 21 and the building block type phase-change heat storage units and the cavities 11 of the electronic equipment are assembled in a cold assembly mode, namely, the phase-change heat storage modules are assembled under the condition of being lower than the working temperature and the storage temperature of the electronic equipment, and the phase-change heat storage modules are in interference fit after being restored to the room temperature.
