Problems solved by technology
[0004] The outlet oil temperature of the existing oil cooler cannot be adjusted. When the inlet conditions change, the outlet oil temperature will fluctuate violently, which will affect the stability and reliability of the oil cooler. In severe cases, it will affect the normal operation of related equipment

The invention discloses an adjustable-oil-temperature three-dimensional rib pipe oil cooler which comprises a shell. A liquid inlet header is arranged at the upper portion of the shell, and a liquid outlet header is arranged at the lower portion of the shell. The adjustable-oil-temperature three-dimensional rib pipe oil cooler is characterized in that multiple heat transfer pipes are connected between the liquid inlet header and the liquid outlet header and are three-dimensional rib pipes, and the three-dimensional rib pipes are outer three-dimensional rib pipes or inner three-dimensional rib pipes or inner and outer three-dimensional rib pipes; according to the outer three-dimensional rib pipes, multiple three-dimensional protruding units are arranged on the outer surfaces of the three-dimensional rib pipes; according to the inner three-dimensional rib pipes, multiple three-dimensional protruding units are arranged on the inner wall face of the three-dimensional rib pipes; according to the inner and outer three-dimensional rib pipes, multiple three-dimensional protruding units are arranged on the outer surfaces and the inner wall faces of the three-dimensional rib pipes; a partition plate is arranged in each of the liquid inlet header and the liquid outlet header; and a fan is arranged in the shell, an automatic air speed adjusting device is arranged in the fan, a temperature detection device is arranged at the position of an outlet of the liquid outlet header, and the temperature detection device is connected with the automatic air speed adjusting device. The adjustable-oil-temperature three-dimensional rib pipe oil cooler can be widely applied to the fields of energy, chemical engineering, refrigerating and the like.
Description
technical field [0001] The invention relates to heat exchange equipment, in particular to a three-dimensional finned tube oil cooler with adjustable oil temperature. Background technique [0002] Oil cooler is a kind of heat exchange equipment commonly used in hydraulic systems and lubrication systems. High-temperature engine oil or lubricating oil can be recycled after heat exchange with air, and the temperature is lowered, thereby saving energy and improving economy. [0003] Existing oil coolers mainly use plate oil coolers and bellows oil coolers. These two coolers operate in a dusty environment with serious dust and fouling, poor operating stability, high maintenance costs, and low reliability. The cooling performance of the plate oil cooler has been greatly improved compared with the bare pipe, which is 1 to 2 times that of the bare pipe under the same working conditions, but there is still a large room for improvement, which can further improve the heat transfer perfo...
