Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, and more specifically, to an oil cooling device. Background Art

[0002] At present, the oil absorbs the heat generated by the friction of bearings and other parts during the circulation process, so the temperature continues to rise. In order to ensure the safe and reliable operation of the unit, the oil temperature must be controlled within the specified range. If the temperature is too high, the bearings and other parts may be overheated and damaged. It will also reduce the service life of the lubricating oil. If the temperature is too low, the viscosity of the lubricating oil will increase, the friction loss will increase, and even cause the machine to vibrate. Therefore, an oil cooling device is currently used to solve the above problems.

[0003] The utility model patent with patent announcement number CN218564357U discloses a drive box lubricating oil cooling device, including a box body, characterized in that a cooling chamber is provided inside the box body, and a spiral pipe is installed inside the cooling chamber by bolts, a coolant is arranged inside the cooling chamber, a cavity is provided inside the box body, and semiconductor cooling sheets with equidistant structure distribution are installed on the outer walls of the four sides of the cooling chamber by bolts, and a heat dissipation copper tube is plugged on the outer wall of one side of the semiconductor cooling sheet. When the lubricating oil of the utility model passes through the spiral pipe, the coolant will cool down the lubricating oil in the spiral pipe, and the heat dissipation effect of the device is better by cooling the coolant through the semiconductor cooling sheet. At the same time, when the lubricating oil passes through the filter box, the filter screen will filter the impurities therein to prevent the impurities from affecting the quality of the lubricating oil and causing the lubricating effect to decrease. The old lubricating oil can be stored in the waste oil tank, and the new lubricating oil in the oil storage tank is then transported to the shield machine drive box, which is convenient for replacing the shield machine drive box lubricating oil.

[0004] However, in actual use, since the structure cools the coolant through refrigeration fins, more refrigeration fins need to be installed to achieve the cooling effect, which increases the cooling cost. At the same time, the coolant cannot circulate, thereby reducing the uniformity of cooling. Therefore, an oil cooling device is proposed. Utility Model Content

[0018] 1. Compared with the prior art, the arrangement of the condenser, the oil pipeline, the condensing tube, the motor, the water hose, the paddle and the rotating rod can circulate the cooling water condensed by the condenser in the condensing tube, thereby continuously absorbing heat from the oil inside the oil pipeline and maintaining the uniformity of heat absorption, thereby ensuring the cooling efficiency;

[0019] 2. Through the arrangement of the motor, the rotating rod, the fan and the fins, compared with the prior art, the rotation of the fan increases the air flow rate around the oil pipeline, and the heat dissipation of the fins is combined to quickly blow away the surrounding hot air. At the same time, when passing through the motor, the heat generated by the motor can be absorbed, thereby achieving air cooling of the oil pipeline, further improving the cooling efficiency of the oil, and dissipating the heat of the motor, thereby ensuring the normal operation of the motor.
