[0031] The specific use mode and effect of the embodiment are as follows:

[0032] When fixing the PCM machine in the housing 7, the PCM machine body 3 is first inserted into the rectangular through slot of the housing 7. At this time, the PCM machine body 3 is placed on the upper side of the placement plate 17. Then, the knob 6 is manually turned, which drives the pressure plate 16, which is engaged with the outer side of the threaded rod 15, to move downward along the guide post 8. The pressure plate 16 and the placement plate 17 clamp and press the PCM machine body 3 from above and below. When grounding the grounding wire of the PCM machine body 3, the core of the grounding wire of the PCM machine body 3 is wound between the nut of the clamping bolt 14 and the protrusion of the conductive rod 9. Then, the clamping bolt 14 is tightened, and the clamping bolt 14 is inserted into the threaded through hole of the protrusion of the conductive rod 9. The nut of the clamping bolt 14, together with the protrusion of the conductive rod 9, clamps and fixes the core of the grounding wire of the PCM machine body 3. The core of the grounding wire of the PCM machine body 3 is tightly attached to the guide post 8. The conductive rod 9 is placed on the convex surface of the bracket 12 and the box 7 is placed on the ground. Under the elastic force of the compression spring 11, the conductive rod 9 is pressed and moved downward along the through hole of the bracket 12 and the through hole of the box 7. The bottom end of the conductive rod 9 is in close contact with the ground, so that the grounding wire of the PCM body 3 is connected to the ground. When the PCM machine is cooling down, the external power supply supplies power to the fan controller 4 through the wire. The fan controller 4 controls the two sets of fans 13 to start synchronously through the wire. The fan wheel of the fan 13 agitates the air, so that the external air is filtered by the dust of the dustproof pad 5 and then drawn into the box 7 through the oblique through groove of the air duct plate 2 on the left and blown quickly by the fan 13 to the fin structure of the pressure plate 16 and the placement plate 17. This allows the heat of the PCM body 3 dissipated by the fins of the pressure plate 16 and the placement plate 17 to be quickly blown to the oblique through groove of the air duct plate 2 on the right and discharged, thus improving the heat dissipation efficiency of the PCM body 3.

[0033] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient specifications of all components are based on their own technologies, and any method that achieves the desired effect can be implemented.
