Description

Technical Field

[0001] This application relates to the field of hydraulic oil tank cooling technology, and specifically discloses an air-cooled hydraulic oil tank assembly. Background Technology

[0002] As a crucial component of the hydraulic systems in agricultural and construction machinery, the oil tank, in addition to its oil storage function, also plays a role in heat dissipation, air bubble separation, and sedimentation of impurities in the hydraulic oil. Currently, mechanical equipment commonly employs a split-type hydraulic cooling system. This system includes components such as a radiator, temperature control valve, and oil tank, and can adjust the cooling effect according to the temperature of the hydraulic oil to ensure that the hydraulic system operates within its optimal temperature range.

[0003] However, in existing split-type hydraulic cooling systems, the functional modules are installed separately, resulting in low overall system integration. This makes it difficult to match parameters between components, and the separate structures occupy a large amount of space, making installation time-consuming and inconvenient to use. Therefore, the inventors have provided an air-cooled hydraulic oil tank assembly to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of traditional hydraulic cooling systems, which use a split structure, resulting in low overall system integration, large space occupation, and inconvenient installation.

[0005] To achieve the above objectives, the basic solution of this utility model provides an air-cooled hydraulic oil tank assembly, including a tank body, an oil tank chamber located at the bottom of the tank body for containing hydraulic oil, and a controller. The oil tank chamber is connected to a return oil pipeline. A heat dissipation assembly for cooling the hydraulic oil in the return oil pipeline is installed inside the tank body. The heat dissipation assembly includes a heat dissipation fin assembly installed between the inner sides of the tank body and above the oil tank chamber, and a cooling fan installed on the side of the tank body for drawing air into the tank body. A return oil filter is also installed between the return oil pipeline and the oil tank chamber. A tank cover is hinged to the top of the tank body. An overpressure protection assembly is also installed on the outside of the tank body. The two sides of the tank cover are detachably snapped to the two sides of the tank body. A level gauge for measuring the hydraulic oil level inside the oil tank chamber is installed on the side of the oil tank chamber. A protective screen is also detachably installed on the side of the tank body away from the cooling fan. The heat dissipation fin assembly, cooling fan, return oil filter, and level gauge are all electrically connected to the controller.

[0006] The principle and effect of this basic scheme are as follows: 1. Compared with the prior art, this utility model integrates hydraulic oil containment and return oil cooling within the tank body by installing an oil tank chamber and heat dissipation components inside the tank. This results in a compact structure with complete functions, significantly reducing the overall space required for the equipment. The integrated structure not only facilitates the use of the hydraulic oil tank but also improves its cooling efficiency. The overpressure protection component provides overpressure protection for the hydraulic oil tank, making the operation more stable and safer. The level gauge facilitates control of the hydraulic oil return, and the return oil filter filters the hydraulic oil flowing back into the tank chamber, ensuring the quality of the hydraulic oil during circulation. This solves the problems of low overall system integration, large space occupation, and inconvenient installation associated with traditional split-type hydraulic cooling systems.

[0007] Furthermore, the overpressure protection assembly includes a temperature sensor installed on the side of the oil tank chamber for monitoring the temperature of the return oil line, and an overpressure protector installed on the outside of the tank. Both the temperature sensor and the overpressure protector are electrically connected to the controller. By setting the temperature sensor to detect the temperature of the hydraulic oil before it flows back into the oil tank chamber, and by setting the overpressure protector to provide real-time protection for the operational safety inside the oil tank chamber, the normal and safe operation of the oil supply and return in the oil tank chamber is ensured.

[0008] Furthermore, a handle is provided on one side of the lid. The handle facilitates the lifting and opening / closing of the lid and the box body.

[0009] Furthermore, the protective screen includes protective louvers located on the side of the enclosure away from the cooling fan and a protective mesh installed inside the protective louvers. The protective louvers facilitate the formation of a convection channel with the cooling fan, thereby working in conjunction with the heat dissipation fins to cool the oil return pipeline. The protective mesh prevents large impurities from entering the enclosure through the protective louvers and damaging other equipment inside.

[0010] Furthermore, the lid is symmetrically hinged with mounting lugs on both sides, and the body is symmetrically provided with mounting seats on both sides. The mounting lugs and mounting seats can be detachably engaged. By providing mounting seats and mounting lugs, the connection and fixation of the lid and body are facilitated.

[0020] In the specific implementation of this utility model, during use, when the high-temperature hydraulic oil flows back to the oil tank chamber 2 through the return oil pipeline 3, when the temperature sensor 9 detects that the temperature in the return oil pipeline 3 is too high, the controller controls the cooling fan 5 and the heat dissipation fin assembly 4 to be powered on. The cooling fan 5 brings airflow from the outside of the housing 1 into the inside of the housing 1 to cool the equipment inside the housing 1, and then discharges it from the protective screen window 8, achieving the effect of convective cooling. At the same time, the heat dissipation fin assembly 4 performs heat exchange and cooling on the high-temperature hydraulic oil in the return oil pipeline 3, achieving the purpose of cooling the hydraulic oil returning to the tank.
