Description

Technical Field

[0001] The utility model relates to the field of hydraulic oil tanks, in particular to a hydraulic oil tank with heat absorption and energy storage. Background Art

[0002] A hydraulic oil tank is a container used to store the oil required to ensure the operation of the hydraulic system. When the hydraulic system is working, heat will be generated, causing the oil temperature to rise. 30-80°C is the normal operating temperature of the hydraulic oil. When the temperature exceeds the limit allowed for use, the internal leakage of the hydraulic system increases, and the performance of the hydraulic system begins to become unstable. Therefore, the hydraulic oil tank needs to have a cooling mechanism.

[0003] For example, the publication number CN218894810U discloses a dustproof heat-absorbing and energy-storing hydraulic oil tank, including a box body with a cavity inside the box body; a heat-insulating mechanism, which is placed on the right side of the box body and has a heat-insulating effect on the box body; a cooling mechanism, which includes an air-cooling mechanism and a circulation mechanism, the circulation mechanism passes through the cavity and the heat-insulating mechanism and transfers the heat emitted from the box body to the heat-insulating mechanism, and the air-cooling mechanism is placed on the surface of the circulation mechanism and is used to achieve heat dissipation of the circulation mechanism.

[0004] In the above scheme, the hydraulic oil in the hydraulic oil tank is cooled by an air cooling mechanism, but the cooling effect of wind blowing alone is poor and the cooling time is long, so that the temperature of the hydraulic oil is quickly reduced to a suitable range, thereby failing to ensure the normal operation of the hydraulic system. Therefore, a hydraulic oil tank with heat absorption and energy storage is proposed. Utility Model Content

[0005] In view of the above problems existing in the existing hydraulic oil tank, the present utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide a hydraulic oil tank with heat absorption and energy storage, which solves the problems raised by the background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A hydraulic oil tank with heat absorption and energy storage, comprising an oil tank and an insulation box, wherein an oil return pipe and an oil outlet pipe are respectively provided on both sides of the oil tank, and a refueling pipe is provided on the top of the oil tank; an annular cooling plate is fixedly provided on the outer wall of the oil tank, a water cavity is provided inside the annular cooling plate, and a plurality of evenly distributed heat conducting pipes are transversely provided inside the oil tank, and the two ends of the plurality of heat conducting pipes are respectively fixedly connected to the inner walls on both sides of the annular cooling plate, a water inlet pipe and a water outlet pipe are respectively fixedly provided on both sides of the annular cooling plate, and an end of the water outlet pipe away from the annular cooling plate is fixedly connected to the insulation box.

[0009] Preferably, the annular cooling plate is made of a rock wool insulation plate, and an aluminum alloy heat conducting plate is fixedly embedded on the inner wall of the annular cooling plate.

[0010] Preferably, the heat conducting pipe is made of an aluminum alloy pipe.

[0011] Preferably, a plurality of evenly distributed spoiler blocks are fixedly provided on the inner side wall of the annular cooling plate.

[0012] Furthermore, one end of the water inlet pipe away from the annular cooling plate is fixedly connected to an external water supply pipe.

[0013] Preferably, a taking pipe is fixedly provided on one side of the thermal insulation box, and a switch valve is provided on the pipe wall of the taking pipe.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model is provided with an annular cooling plate, a heat conducting pipe, a water inlet pipe, a water outlet pipe and a heat preservation box, so that external cooling water can be discharged into the interior of the annular cooling plate through the water inlet pipe. Since the annular cooling plate is wrapped around the outside of the oil tank, the temperature of the surface of the oil tank can be reduced. At the same time, the cooling water will also enter the interior of the heat conducting pipe. The heat conducting pipe can exchange heat between the hydraulic oil and the cooling water pipe, so that the temperature of the hydraulic oil is quickly reduced to a suitable range. At the same time, the heated cooling water will be collected in the interior of the heat preservation box through the water outlet pipe for standby.

[0016] 2. The utility model uses an aluminum alloy heat conduction plate arranged inside the annular cooling plate. The aluminum alloy heat conduction plate can quickly transfer the cold air of the cooling water to the surface of the oil tank, so that the surface of the oil tank and the hydraulic oil inside are cooled.
