Example one

As shown in fig. 1 to 2, fig. 1 shows only the structures of a radiator 10 and a radiator fan 20 in a cooling system for an on-vehicle generator set, the structures of the other portions are not shown, and fig. 2 shows only a schematic structural view of the radiator 10. The embodiment provides a cooling system for a vehicle-mounted generator set, which comprises a radiator 10, a cooling fan 20, a circulating water pump and a kettle. The radiator 10 includes a left water chamber 11, a right water chamber 13, and a radiator core 12, the left water chamber 11 includes a second water chamber 113 in which the first water chamber 111 and the first water chamber 111 are not communicated with each other, and the right water chamber 13 includes a third water chamber 131 and a fourth water chamber 133 different from the third water chamber 131. The radiator core 12 includes a generator radiator pipe, an engine radiator pipe 121, and a radiator fin. The first water chamber 111 is communicated with the third water chamber 131 through a heat dissipation pipe of the generator, and the first water inlet 112 and the first water outlet 132 are respectively formed on the first water chamber 111 and the third water chamber 131. The first water inlet 112 is communicated with a cooling channel in the generator through a water inlet pipeline, and the first water outlet 132 is communicated with the cooling channel in the generator through a water return pipeline. Second chamber 113 is in communication with fourth chamber 133 via engine radiator tube 121, and second chamber 113 and/or fourth chamber 133 are in communication with the cooling passages within the engine via piping. The radiator fan 20 is installed at the rear end of the radiator 10 and serves to cool the generator radiator pipe and the engine radiator pipe 121, and in some cases, the radiator fan 20 cannot cool all of the generator radiator pipe and the engine radiator pipe 121, and there is a portion of the generator radiator pipe and the engine radiator pipe 121 that is not in the cooling range of the radiator fan 20, but as long as most of the generator radiator pipe and the engine radiator pipe 121 can be cooled, a good cooling effect can be ensured.

Since the cooling air volume required for the engine is large, the height of second chamber 113 is greater than the height of first chamber 111, and accordingly, the height of fourth chamber 133 is also greater than the height of third chamber 131.

In this embodiment, through improving the structure to left hydroecium 11 and right hydroecium 13 for engine and generator respectively use one set of cooling line, thereby when having avoided one set of cooling line of sharing, the coolant liquid that has higher temperature causes the generator operating temperature too high after entering into the generator, and then causes the emergence of the circumstances such as generator life-span reduction or frequent shut down or burnt out.

As a further improvement of the above solution, the second water chamber 113 includes an inlet chamber 114 and an outlet chamber 115, the inlet chamber 114 and the outlet chamber 115 are separated by a partition, and the inlet chamber 114 and the outlet chamber 115 are not directly connected. The heat pipe 121 of the engine includes a heat pipe of the inlet chamber and a heat pipe of the outlet chamber, the inlet chamber 114 is provided with a second inlet 116, the inlet chamber 114 is communicated with one end of the heat pipe of the inlet chamber, the outlet chamber 115 is provided with a second outlet 117, the outlet chamber 115 is communicated with one end of the heat pipe of the outlet chamber, and the fourth water chamber 133 is communicated with the other ends of the heat pipe of the inlet chamber and the heat pipe of the outlet chamber. The cooling water flowing out of the engine flows from the inlet chamber 114 to the fourth water chamber 133 and then flows from the fourth water chamber 133 to the outlet chamber 115, so that the moving path of the cooling water in the radiator core 12 is doubled, thereby prolonging the cooling time of the cooling water and improving the cooling effect.

One end of the cleaning pipe 31 is a blind end, the other end is communicated with a water supply pump 34 through a hose 33, the preferred lower end is a blind end, the water supply pump 34 is communicated with a water storage tank 35, and the water storage tank 35 and the water supply pump 34 can be independently fixed on the frame or can be fixed on the frame together with the radiator 10. The pipe frame 36 is used for fixing the cleaning pipe 31, and the traversing device 37 is used for driving the pipe frame 36 to move back and forth along the transverse direction, and enabling the movable area of the cleaning pipe 31 to cover the front end of the radiator core 12, thereby ensuring that the water sprayed by the nozzle 32 can clean the front end surface of the radiator core 12.

The reaction force of the water sprayed from the nozzles 32 causes the pipe frame 36 to move in a direction away from the front end surface of the radiator core 12, and in the present embodiment, by restraining the upper and lower ends of the pipe frame 36, the pipe frame 36 does not move in the above-described direction, thereby ensuring the reliability of the cleaning device 30.

As a further improvement of the above scheme, the upper cross beam 371 is provided with a first sliding groove 372 having an arc-shaped cross section, the upper cross beam 361 is provided with a first protrusion 362 sliding in the first sliding groove 372 and corresponding to the first sliding groove 372, the lower cross beam 38 is provided with a second sliding groove 381 having an arc-shaped cross section, and the lower cross beam 364 is provided with a second protrusion 365 sliding in the second sliding groove 381 and corresponding to the second sliding groove 381.
