When the hydraulic oil moves in the hydraulic oil path, more heat is often generated.
The high-temperature hydraulic oil firstly passes through the oil inlet main pipe 111 and then is split into a plurality of oil inlet branch pipes 112, so that the heat dissipation in the high-temperature hydraulic oil can be accelerated. And gaps are formed among the oil inlet branch pipes 112, so that the condition that heat is mutually transferred by high-temperature hydraulic oil in the oil inlet branch pipes 112 can be reduced, and heat exchange between the high-temperature hydraulic oil and the external environment can be promoted. The cooling device 2 in this scheme cools down hydraulic oil in advance oil assembly 11 department, can reduce the temperature of high temperature hydraulic oil uniformly, has solved the inhomogeneous problem of cooling in the traditional hydraulic tank.
Further, the cooling device 2 includes a water tank 21, a first cooling pipe 23, a second cooling pipe 24, and a refrigerator 22, the refrigerator 22 is installed in the water tank 21, the water tank 21 is used for storing cooling liquid, the refrigerator 22 is used for cooling the cooling liquid, an input end of the first cooling pipe 23 is connected with the water tank 21, the first cooling pipe 23 is threaded around the oil inlet manifold 111, and an output end of the first cooling pipe 23 is connected with the water tank 21;

The refrigerator 22 and the cooling liquid are arranged in the water tank 21, and the refrigerator 22 can cool the cooling liquid at the moment, so that the cooling liquid can be kept at a lower temperature at any time. Part of the low-temperature cooling liquid flows in the first cooling pipeline 23, and the first cooling pipeline 23 is in threaded surrounding on the oil inlet main pipe 111, so that high-temperature hydraulic oil and the low-temperature cooling liquid exchange heat, and the temperature of the hydraulic oil in the oil inlet main pipe 111 is effectively reduced.
In the oil inlet branch pipe 112 where the cooled hydraulic oil flows, at this time, another part of low-temperature hydraulic oil flows in the second cooling pipeline 24, and the second cooling pipeline 24 is screwed around the inside of the oil inlet branch pipe 112, so that the low-temperature cooling liquid can exchange heat with the cooled hydraulic oil, and the temperature of the hydraulic oil is further reduced, so that when the hydraulic oil enters the hydraulic oil tank 1, the temperature is reduced to a normal temperature state.
In addition, the plurality of second cooling pipelines 24 and the plurality of oil inlet branch pipes 112 are in one-to-one correspondence, so that each second cooling pipeline 24 can perform heat exchange with the oil inlet branch pipes 112, and therefore uneven cooling of hydraulic oil is reduced, and partial hydraulic oil is not completely cooled yet.
Further, the first cooling pipe 23 includes a first water pump 231 and a first sub cooling pipe 232, an input end of the first water pump 231 is communicated with the water tank 21, an output end of the first water pump 231 is connected with an input end of the first sub cooling pipe 232, the first sub cooling pipe 232 is threaded around the oil inlet manifold 111, an output end of the first sub cooling pipe 232 is communicated with the water tank 21, and the first water pump 231 is electrically connected with the control system.
Wherein, the control system starts the first water pump 231, so that the first water pump 231 pumps the low-temperature cooling liquid from the water tank 21 into the first sub-cooling pipe 232, and at this time, the low-temperature cooling liquid continuously flows in the first sub-cooling pipe 232, then flows to the output end of the first sub-cooling pipe 232, and then flows into the water tank 21, thereby completing the circulation route of the cooling liquid.
Because the first sub-cooling pipe 232 is threaded around the oil inlet manifold 111, the low-temperature cooling liquid flows in the first sub-cooling pipe 232 and exchanges heat with the high-temperature hydraulic oil, so that the purpose of reducing the temperature of the hydraulic oil is achieved.

Because the second sub-cooling pipe 242 is threaded around the oil inlet branch pipe 112, the low-temperature cooling liquid exchanges heat with the high-temperature hydraulic oil while flowing in the second sub-cooling pipe 242, thereby achieving the purpose of reducing the temperature of the hydraulic oil.

Further, the hydraulic system is provided with a first temperature sensor, the first temperature sensor is used for detecting the temperature of hydraulic oil in the oil inlet manifold 111, and the first temperature sensor is electrically connected with the control system.
The first temperature sensor can recognize the temperature change of the hydraulic oil in the oil inlet hydraulic system at any time, when the temperature value of the hydraulic oil in the hydraulic system exceeds a preset range, the first temperature sensor can transmit the signal to the control system, and the control system timely starts the first water pump 231 and the second water pump 241, so that the first water pump 231 pumps low-temperature cooling liquid from the water tank 21 and transmits the low-temperature cooling liquid to the first sub-cooling pipe 232 to cool the high-temperature hydraulic oil in the oil inlet main pipe 111. The second water pump 241 pumps out the low-temperature cooling liquid from the water tank 21 and delivers the low-temperature cooling liquid into the second sub-cooling pipe 242 so that the second sub-cooling pipe 242 can cool the oil inlet sub-pipe 112.
At this time, when the high-temperature hydraulic oil in the hydraulic system flows into the oil feed manifold 111, the low-temperature coolant has already flowed in the first sub-cooling pipe 232 or the second sub-cooling pipe 242, so that the temperature of the hydraulic oil can be effectively and rapidly lowered.

Further, the flow direction of the cooling fluid in the first sub-cooling pipe 232 is opposite to the flow direction of the hydraulic oil in the oil inlet manifold 111;
the flow direction of the coolant in the second sub-cooling pipe 242 is opposite to the flow direction of the hydraulic oil in the oil feed branch pipe 112.
