Fig. 1 is a front sectional view of an embodiment of a heat dissipation device for a shock absorber, and as shown in the figure, the heat dissipation device for a shock absorber comprises a nitrogen cylinder 1, an oil inlet check valve, an oil outlet check valve and a heat dissipation fin 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 channel 4 is communicated with a first oil passing cavity 6 inside the flow dividing 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 an oil storage cavity 12 in the nitrogen cylinder 1 through a third oil passing cavity 11. The oil storage chamber 12 is communicated with a fifth oil passing chamber 14 through a fourth oil passing chamber 13, and an oil outlet channel 15 communicated with the fifth oil passing chamber 14 is communicated with an oil outlet one-way valve. An oil inlet one-way valve plate 16 is arranged at the outlet of the second oil inlet channel 4, and an oil outlet one-way valve plate 17 is arranged at the outlet of the fifth oil passing cavity 14. The shock absorber heat dissipation device carries out heat dissipation treatment on the damping oil, and normal use of the shock absorber is guaranteed. Damping oil enters the first oil inlet channel 3 through the oil inlet one-way valve, then enters the adjusting cavity 10, and then enters the first oil passing cavity 6 through the second oil inlet channel 4, and the oil inlet one-way valve plate 16 is jacked open. The damping oil enters the first cooling cavity 7 through the first oil passing cavity 6, and primary cooling of the damping oil is achieved. The damping oil after primary cooling enters a second cooling cavity 9 through a second oil passing cavity 8 to carry out secondary cooling 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 the unidirectional circulation of the damping oil is completed. The arrangement of the oil inlet one-way valve plate 16 ensures that the 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 the damping oil can only move from the fifth oil passing cavity 14 to the oil outlet channel 15.
An air faucet is arranged at one end, far away from the second oil inlet channel 4, of the nitrogen cylinder 1, the air faucet is provided with an air faucet sealing cover 21 matched with the air faucet, and a sealing ring is sleeved at the joint of the air faucet sealing cover 21 and the nitrogen cylinder 1. The air nozzle supplies nitrogen to the inside of the air storage cavity 19, and the sealing cover 21 and the sealing ring of the air nozzle ensure the sealing performance of the inside of the air storage cavity 19.

The piston plate 20 compresses the space of the oil storage chamber 12 under the pressure of the nitrogen gas in the gas storage chamber 19, presses the damping oil in the oil storage chamber 12 to the fourth oil passing chamber 13, and finally presses the damping oil into the oil outlet one-way 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 size of the oil inlet one-way valve plate 16 and the size of the oil outlet one-way valve plate 17 are arranged, so that the damping oil can move only in one direction, and the damping oil can be fully cooled.
The second oil passing cavity 8 is of an annular structure, the first cooling cavity 7 and the second cooling cavity 9 are symmetrically arranged, and the ring formed by the first cooling cavity 7 and the second cooling cavity 9 is matched with the second oil passing cavity 8. The shape of the second oil passing cavity 8 is set, 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 damping oil which is cooled for the first time and the damping oil which is cooled for the second time are separated, and the heat dissipation effect of the nitrogen cylinder 1 on the damping oil is improved.
The interior of the adjusting cavity 10 is provided with a pressure adjusting valve 18, and the top end of the pressure adjusting valve 18 is matched with the adjusting cavity 10. The pressure regulating valve 18 may control the damping oil introduced into the interior of the nitrogen cylinder 1.
The outer part of the nitrogen cylinder 1 is surrounded with evenly distributed radiating fins 2, and the length of the radiating fins 2 is larger than that of the first cooling cavity 7. The length of the radiating fins 2 is set, so that the radiating effect of the nitrogen cylinder 1 is further ensured.
The shunting block 5 is connected with the inner side wall of the nitrogen cylinder 1 through a screw, and a positioning sleeve is sleeved at the joint of the screw and the shunting block 5. The arrangement of the shunting block 5 ensures the one-way cooling circulation of the damping oil in the nitrogen cylinder 1 and the completely separated primary cooling process and secondary cooling process.
When the oil-out check valve is used, the first oil inlet channel 3 is communicated with the oil inlet check valve, and the oil outlet channel 15 is communicated with the oil outlet check valve. Damping oil enters the nitrogen cylinder 1 through the oil inlet check valve, and moves out of the nitrogen cylinder 1 through the oil outlet check valve to complete the heat dissipation process of the damping oil.
