Description

Technical Field

[0001] This utility model relates to the field of hydraulic station cooling technology, specifically a hydraulic station cooling device. Background Technology

[0002] The cooling device of a hydraulic power unit is a key component used to regulate the oil temperature of a hydraulic system. Its core function is to maintain the oil temperature within a reasonable range through heat dissipation, ensuring stable system operation. Common types include air-cooled, water-cooled, and oil-cooled units. The cooling device uses air as a cooling medium, and forces the air to flow through a fan or air pump to remove the heat from the hydraulic oil. This cooling method has a simple structure and low cost, and is suitable for small hydraulic power units or hydraulic systems with low cooling requirements.

[0003] Adding heat sinks to the surface of the cooling box of the cooling device can significantly increase the heat dissipation area of ​​the cooling box, which is conducive to transferring the heat inside the box to the surrounding environment more quickly and improving the overall heat dissipation efficiency. At the same time, dust in the air can easily accumulate on the surface of the heat sink. The common method is for staff to use soft brushes or vacuum cleaners to clean the dust on the surface of the heat sink. If the staff does not clean it in time, the accumulated dust will block the gaps between the heat sinks, affect air circulation, hinder convection formation, and reduce the heat dissipation effect. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic station cooling device that increases the heat dissipation speed of the cooling box while protecting the heat sinks on the front and rear sides of the cooling box to prevent dust from accumulating on the surface of the heat sinks, thus solving the problem of dust easily accumulating on the surface of the heat sinks on the outside of the cooling device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic station cooling device, including a cooling box, a U-shaped tube fixedly installed inside the cooling box, an inlet pipe embedded on one side of the top of the cooling box, an outlet pipe embedded on the other side of the top of the cooling box, an air pump fixedly installed on the side of the cooling box, a second air jet plate fixedly installed on the inner side of the cooling box on one side of the U-shaped tube, an outlet pipe installed on the side of the air pump opposite to the cooling box, one end of the outlet pipe extending into the cooling box being fixedly connected to the second air jet plate, heat sinks fixedly installed in a rectangular array on both the front and rear sides of the cooling box, an air jet plate fixedly installed on both the front and rear sides of the cooling box above the two rows of heat sinks, connecting pipes installed on both sides of the outlet pipe, and the ends of the two connecting pipes opposite to the outlet pipe being fixedly connected to the two first air jet plates.

[0006] Preferably, the ends of the inlet pipe and the outlet pipe that extend into the cooling tank are both fixedly connected to the U-shaped pipe.

[0007] Preferably, the air pump is equipped with an air intake pipe on the side away from the cooling box.

[0008] Preferably, an inspection door is installed on the top of the cooling tank on the opposite side of the inlet pipe and the outlet pipe via a hinge.

[0009] Preferably, a bracket is installed at the bottom of the air pump, and the bottom of the bracket is fixedly connected to the side of the cooling box.

[0010] Preferably, the cooling box has an air outlet on the side away from the air pump, and a mesh frame is installed inside the air outlet.

[0011] Preferably, a fixing frame is welded to the bottom of the cooling box, and the bottom of the fixing frame has fixing holes arranged in a rectangular array.

[0012] Preferably, the nozzles at the bottom of the two jet plates are rectangular, and the rectangular nozzles correspond to the two rows of heat sinks.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting up heat sinks, connecting pipes, and jet plates, allows the air pump to deliver clean air to the cooling box through the air outlet pipe to cool the hydraulic oil. During this process, the heat sinks on the front and rear sides of the cooling box increase the heat dissipation area of ​​the cooling box, and the heat sinks diffuse the absorbed heat to the outside. The air outlet pipe delivers clean air to two jet plates through two connecting pipes. The two jet plates blow air onto the surface of the two rows of heat sinks, accelerating the airflow speed near the heat sinks.

The hydraulic oil enters the U-shaped pipe 16 from the inlet pipe 4, and the hydraulic oil inside the U-shaped pipe 16... Oil flows back into the pipeline from the outlet pipe 6. An air pump 8 is fixedly installed on the side of the cooling box 1. A bracket 17 is installed at the bottom of the air pump 8, and the bottom of the bracket 17 is fixedly connected to the side of the cooling box 1. The bracket 17 fixes the air pump 8 to the side of the cooling box 1. An air intake pipe 9 is installed on the side of the air pump 8 away from the cooling box 1. The air intake pipe 9 is connected to a pipeline that delivers clean air. The air pump 8 draws air through the air intake pipe 9. A jet plate 15 is fixedly installed on the inner side of the cooling box 1 on one side of the U-shaped pipe 16. An air pump 8 is installed on the side opposite to the cooling box 1. Equipped with an exhaust pipe 14, one end of the exhaust pipe 14 extending into the cooling box 1 is fixedly connected to the second jet plate 15. Cooling box 1 has heat sinks 2 fixedly mounted in a rectangular array on both the front and rear sides. Above the two rows of heat sinks 2, the cooling box 1 has two jet plates 3 fixedly mounted on both the front and rear sides. Connecting pipes 7 are installed on both sides of the exhaust pipe 14. The ends of the two connecting pipes 7 facing away from the exhaust pipe 14 are fixedly connected to the two jet plates 3.

[0026] Example 2

[0027] like Figures 1-4 As shown, the hydraulic station cooling device proposed in this utility model, compared with the first embodiment, further includes: an air outlet 12 and a grid frame 13. The cooling box 1 has an air outlet 12 on the side away from the air pump 8, and a grid frame 13 is installed inside the air outlet 12.

The air pump 8 draws in air through the suction pipe 9 and then delivers the clean air to the air jet plate 15 inside the cooling box 1 through the air outlet pipe 14. The air jet plate 15 blows the air... The air blown onto the surface of the U-shaped tube 16 causes the high-temperature hydraulic oil inside the U-shaped tube 16 to dissipate heat outward through the tube wall. The flowing air carries away the heat, and the air with increased temperature inside the cooling box 1 is discharged from the side air outlet 12. The heat sinks 2 on the front and rear sides of the cooling box 1 increase the heat dissipation area of ​​the cooling box 1. The heat sinks 2 diffuse the absorbed heat to the outside. The air outlet pipe 14 delivers clean air to the two jet plates 3 through two connecting pipes 7. The two jet plates 3 blow air onto the surface of the two rows of heat sinks 2, accelerating the airflow speed near the heat sinks 2.
