Description

Technical Field

[0001] The utility model relates to the field of hydraulic oil tanks, and more specifically, to a heat dissipation oil tank for a hydraulic system. Background Art

[0002] Hydraulic systems, as a power transmission and control system, are currently widely used in various mechanical equipment, such as various engineering machinery, machine tools, weaponry, aerospace equipment, and manufacturing systems. However, hydraulic systems, especially high-speed hydraulic control systems, suffer from significant power loss. This power loss is converted into heat, causing the hydraulic oil temperature to rise. This elevated hydraulic oil temperature can lead to poor hydraulic system performance, or even malfunction. Hydraulic system failures and unexpected shutdowns are often caused by excessively high hydraulic oil temperatures.

[0003] At present, hydraulic oil tanks are generally equipped with heat dissipation structures and auxiliary fans for heat conduction and heat dissipation. However, the heat dissipation area of ​​the fixed heat dissipation module is limited, and the thermal conductivity efficiency is also limited. This results in a very low heat dissipation ceiling of the device, making it difficult to maintain high-intensity continuous operation of the hydraulic system. Utility Model Content

[0007] As a further description of the above technical solution: a cavity is provided inside the heat dissipation fin, and the cavity is communicated with the interior of the vertical conduit.

[0008] As a further description of the above technical solution: the blowing assembly includes a fan and a dust cover, the outer side of the fan is fixedly connected to the connecting shell, the dust cover is arranged on the outer side of the fan, and the outer side of the dust cover is fixedly connected to the connecting shell.

[0009] As a further description of the above technical solution: pipe connectors are installed on the opposite sides of the upper box body and the lower box body.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0021] See also Figure 1-4 In the utility model, a heat dissipation oil tank for a hydraulic system includes an upper box body 1 and a lower box body 2. Two fixing plates 3 are connected between the upper box body 1 and the lower box body 2. Vertical pipes 4 arranged at equal distances are installed between the upper box body 1 and the lower box body 2. Both sides of the vertical pipes 4 are fixedly connected with heat dissipation fins 5 arranged at equal distances. A connecting shell 6 is installed on the back between the upper box body 1 and the lower box body 2, and a blowing assembly 7 is installed inside the connecting shell 6.

[0022] In the present invention, the upper box body 1 is matched with the lower box body 2 by using the fixing plate 3 to connect them into a whole. When in use, the hydraulic system is connected from the top upper box body 1 so that the high-temperature hydraulic oil is introduced into the interior of the upper box body 1. After the high-temperature hydraulic oil enters the upper box body 1, it is evenly dispersed downward into the interior of each vertical duct 4, and the blowing assembly 7 on the back is simultaneously started to dissipate heat for the vertical duct 4. The heat dissipation area of ​​the device is greatly increased through the heat dissipation fins 5, and the hydraulic oil is evenly dispersed and dissipated, thereby achieving the advantages of increased heat dissipation area, improved heat dissipation efficiency, and improved continuous working stability of the hydraulic system. This solves the problem that the hydraulic oil tank in the prior art is generally equipped with a heat dissipation structure and the auxiliary fan is used for heat conduction and heat dissipation, but the heat dissipation area of ​​the fixed heat dissipation module is limited, and the heat conduction efficiency is also limited, which leads to a very low heat dissipation upper limit of the device and it is difficult to maintain high-intensity continuous operation of the hydraulic system.

[0023] See also Figure 2 , wherein: a cavity 51 is provided inside the heat dissipation fin 5 , and the cavity 51 is communicated with the interior of the vertical pipe 4 .

[0024] In the present invention, when the hydraulic oil passes through the interior of the vertical conduit 4 through the cavity 51 , the contact area with the heat dissipation fins 5 is increased through the cavity 51 , thereby further improving the heat dissipation effect.

[0025] See also Figure 3 and Figure 4 , wherein: the blowing assembly 7 includes a fan 71 and a dust cover 72, the outer side of the fan 71 is fixedly connected to the connecting shell 6, the dust cover 72 is arranged on the outer side of the fan 71, and the outer side of the dust cover 72 is fixedly connected to the connecting shell 6.

[0026] In the present invention, the heat dissipation efficiency is increased by starting the fan 71 to blow air to the heat dissipation fins 5 and the vertical duct 4 from the back.

[0027] See also Figure 1 , wherein: a pipe connector 8 is installed on the opposite side of the upper box body 1 and the lower box body 2.

[0028] In the present invention, the pipe connector 8 facilitates the connection between the upper box body 1 and the lower box body 2 and the pipes of the hydraulic system.

[0029] See also Figure 3 , wherein: the front of the vertical guide tube 4 is fixedly connected with a horizontal pull rod 41.

[0030] In the present invention, the multiple vertical pipes 4 are fixed and pulled in transversely by the horizontal pull rods 41, thereby improving the stability of the vertical pipes 4 and improving the pressure resistance.

[0031] See also Figure 3 , wherein: the top cross-section of the vertical conduit 4 is a longitudinally long rectangular strip.

[0032] In the present invention, the vertical conduit 4 has a longitudinally long rectangular cross-section when viewed from above, and the external surface area is greatly increased in conjunction with the heat dissipation fins 5, thereby improving the heat exchange efficiency.
