Problems solved by technology

[0002] At present, in the process of industrial production, heat treatment is required for metal products, especially some construction machinery parts. In order to achieve certain material properties, heat treatment is required. In heat treatment, the most common quenching process usually heats metal materials , heat preservation, and rapid cooling process, through the rapid cooling method, the grains inside the metal do not have time to grow, and the material performance is improved. Usually, it is necessary to use a quenching medium for cooling, usually using quenching oil. For large parts, in order to ensure complete hardening, it needs to be placed It is carried out in an oil tank, such as a slewing bearing seat, etc., but during quenching, the temperature of the internal quenching medium rises, and circulation cooling is required. The existing quenching equipment is to pump the quenching oil in the quenching tank to the cooling pool through a water pump. Cooling, such quenching takes a long time, the quenching efficiency is low, and the labor intensity is high. Some cooling circulation systems use plate heat exchangers for heat exchange, which mainly drives the heat in the quenching oil through the flow of cooling medium, relying on Single medium flow, poor heat exchange efficiency, and the whole system is integrated, poor flexibility in use, and cannot realize the complementarity between water cooling and natural heat dissipation

[0003] Combined with another application submitted by the applicant for the cooling circulation system of the heat treatment and quenching process, in order to better provide heat dissipation and improve heat dissipation efficiency, it is necessary to use an oil cooler for independent circulation of oil cooling. Some existing The cooling devices have corresponding defects and cannot be used directly

As long as the device is cooled by water circulation, the water circulation and the oil circulation are relatively independent, and there is no interaction, and the oil cannot be cooled. The circulation tube forms a package, which consumes a lot of heat dissipation
