Novel mainboard radiator, intercooler, locomotive radiating device and motor vehicle

The utility model belongs to the technical field of automobile radiating devices, and discloses a novel mainboard radiator, an intercooler, a locomotive radiating device and a motor vehicle, a mold layer is sleeved on a mainboard, a stretching groove is stretched on the surface of the mold layer, and a radiating pipe is inserted in the stretching groove. The die layer is stretched upwards or downwards or stretched up and down at the same time, a stretching groove is formed in the die layer, the heat dissipation pipe is welded in the stretching groove, then the die layer is arranged on the mainplate in a sleeving mode, and fixing of the heat dissipation pipe is achieved. Buffering is carried out during bumping and vibration, the service life of the heat dissipation pipes is prolonged, andtherefore the service life of the radiator of each vehicle is prolonged, the rejection rate is reduced, the reloading rate of components of the whole radiator is reduced, the expenditure of tens of millions of national vehicle
