Description

Technical Field

[0001] The utility model relates to the technical field of oil pressure machine temperature reduction, in particular to an oil pressure machine oil temperature reduction mechanism. Background Art

[0002] A hydraulic press is a machine that uses liquid as a working medium to transfer energy to achieve various processes. During the operation of the hydraulic press, a large amount of heat will be generated due to factors such as friction, compression, and shear. If the heat is not dissipated in time, the oil temperature will rise, affecting the normal operation of the hydraulic press. Therefore, the cooling technology of the hydraulic press is very important. With the continuous development of technology, the cooling technology of the hydraulic press is also constantly improving and innovating. At present, some new cooling technologies have begun to be applied to hydraulic presses, such as heat pipe technology, phase change material technology, nanotechnology, etc. The application of these new technologies can improve the heat dissipation efficiency of the hydraulic press, reduce the oil temperature, and improve the working stability and reliability of the hydraulic press.

[0003] The oil temperature reduction mechanism of the hydraulic press is a mechanism used to reduce the temperature of the hydraulic system. In the hydraulic system, due to the continuous circulation of the hydraulic oil and mechanical friction, the system temperature will gradually increase, which may cause problems such as hydraulic oil deterioration, accelerated equipment wear and system performance degradation. Therefore, the application of the oil temperature reduction mechanism of the hydraulic press is becoming more and more widespread.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The existing oil pressure cooling mechanism usually adopts air cooling or water cooling, but due to the low efficiency of components such as the radiator and the fan, the cooling efficiency is also low, which may affect the performance and stability of the system; 2. The existing oil pressure cooling mechanism usually adopts a single cooling method and cannot evenly cool all parts of the hydraulic system, which may cause the local temperature of the system to be too high, affecting the reliability and life of the system.
