Fig. 1 is a front sectional view of an embodiment of a heat dissipating device for a shock absorber according to the present invention, as shown in the drawing, comprising a nitrogen cylinder 1, an oil inlet check valve, an oil outlet check valve, and a heat sink 2. The oil inlet one-way valve is communicated with a first oil inlet channel 3 of the nitrogen cylinder 1, and an adjusting cavity 10 communicated with the first oil inlet channel 3 is communicated with a second oil inlet channel 4. The second oil inlet duct 4 is communicated with a first oil passing cavity 6 inside the split flow block 5, and the first oil passing cavity 6 is communicated with a first cooling cavity 7. The second oil passing cavity 8 communicated with the first cooling cavity 7 is communicated with the second cooling cavity 9, and the second cooling cavity 9 is communicated with the oil storage cavity 12 inside the nitrogen cylinder 1 through the third oil passing cavity 11. The oil storage cavity 12 is communicated with the fifth oil passing cavity 14 through the fourth oil passing cavity 13, and an oil outlet channel 15 communicated with the fifth oil passing cavity 14 is communicated with an oil outlet one-way valve. The outlet of the second oil inlet channel 4 is provided with an oil inlet one-way valve plate 16, and the outlet of the fifth oil passing cavity 14 is provided with an oil outlet one-way valve plate 17. The damper heat dissipation device carries out heat dissipation treatment on damping oil, so that the normal use of the damper is ensured. Damping oil enters the first oil inlet channel 3 through the oil inlet check valve and then enters the adjusting cavity 10, and then the oil inlet check valve plate 16 is jacked up when entering the first oil passing cavity 6 through the second oil inlet channel 4. Damping oil enters the first cooling cavity 7 through the first oil passing cavity 6, so that primary cooling of the damping oil is realized. The damping oil after primary cooling enters a second cooling cavity 9 through a second oil passing cavity 8, and secondary cooling is carried out on the damping oil. The cooled damping oil enters the oil storage cavity 12 through the third oil passing cavity 11, and the damping oil in the oil storage cavity 12 sequentially passes through the fourth oil passing cavity 13 and the fifth oil passing cavity 14 to the oil outlet channel 15, so that unidirectional circulation of the damping oil is completed. The arrangement of the oil inlet one-way valve plate 16 ensures that damping oil can only move from the second oil inlet channel 4 to the first oil passing cavity 6. The arrangement of the oil outlet one-way valve plate 17 ensures that damping oil can only move from the fifth oil passing cavity 14 to the oil outlet channel 15.
One end of the nitrogen cylinder 1 far away from the second oil inlet channel 4 is provided with an air tap, the air tap is provided with an air tap sealing cover 21 matched with the air tap, and a sealing ring is sleeved at the joint of the air tap sealing cover 21 and the nitrogen cylinder 1.

The piston sheet 20 compresses the space of the oil storage chamber 12 under the pressure of nitrogen in the gas storage chamber 19, presses damping oil in the oil storage chamber 12 to the fourth oil passing chamber 13, and finally inputs the damping oil into the oil outlet check valve.
The oil inlet one-way valve plate 16 is larger than the outlet of the second oil inlet channel 4, and the oil outlet one-way valve plate 17 is larger than the outlet of the fifth oil passing cavity 14. The oil inlet one-way valve plate 16 and the oil outlet one-way valve plate 17 are arranged in size, so that damping oil can move only in one direction, and the damping oil can be fully cooled.

The second oil passing cavity 8 is arranged so that one half of the second oil passing cavity is communicated with the first cooling cavity 7, the other half of the second oil passing cavity is communicated with the second cooling cavity 9, the primary cooling damping oil and the secondary cooling damping oil are separated, and the heat dissipation effect of the nitrogen cylinder 1 on the damping oil is improved.
The regulating cavity 10 is internally provided with a pressure regulating valve 18, and the top end of the pressure regulating valve 18 is matched with the regulating cavity 10. The pressure regulating valve 18 controls the damping oil entering the inside of the nitrogen cylinder 1.
The outside of the nitrogen cylinder 1 is circumferentially provided with evenly distributed cooling fins 2, and the length of the cooling fins 2 is longer than that of the first cooling cavity 7. The length of the radiating fin 2 is set to further ensure the radiating effect of the nitrogen cylinder 1.
The shunt block 5 is connected with the inner side wall of the nitrogen cylinder 1 through a screw, and a locating sleeve is sleeved at the joint of the screw and the shunt block 5. The arrangement of the split flow block 5 ensures unidirectional cooling circulation of damping oil in the nitrogen cylinder 1, and completely separated primary cooling process and secondary cooling process.
When the oil inlet device is used, the first oil inlet channel 3 is communicated with the oil inlet one-way valve, and the oil outlet channel 15 is communicated with the oil outlet one-way valve. Damping oil enters the nitrogen cylinder 1 through an oil inlet one-way valve, and then moves out of the nitrogen cylinder 1 through an oil outlet one-way valve, so that the heat dissipation process of the damping oil is completed.
Therefore, the heat dissipation device of the shock absorber adopts the structure, and the nitrogen cylinder is provided with the oil inlet one-way valve and the oil outlet one-way valve, so that the unidirectional circulation heat dissipation of damping oil in the nitrogen cylinder is realized, and the heat dissipation effect of the damping oil is good.
