[0024] Please see Figures 1-4 This utility model provides an embodiment of a hydraulic system heat dissipation device for a hydraulic press, including an outer casing 2, a hydraulic oil tank 11 on the right side of the outer casing 2, a side cover 3 on the top of the outer casing 2, an air inlet hood 14 fixedly installed at the front end of the outer casing 2, a fan 15 fixedly installed at the top and bottom of the front end of the outer casing 2, a slot 20 is opened at the front end of the top of the air inlet hood 14, and a filter screen 19 is inserted into the slot 20.

The filter 19 can be used to filter and remove large, irregularly shaped lint and other debris in the air drawn in from the outside, thereby reducing the amount of dust and debris entering the device during the heat dissipation process and providing auxiliary dust prevention for the inside of the device.

[0027] An air outlet hood 13 is fixed to the rear end of the outer casing 2, and the front end of the air outlet hood 13 penetrates the interior of the rear end of the outer casing 2. A flap 23 is horizontally arranged inside the rear end of the air outlet hood 13, and a rotating rod 22 is horizontally fixed to the top of the front end of the flap 23. Multiple sets of flaps 23 are equally spaced inside the rear end of the air outlet hood 13, and the two sides of the rotating rod 22 penetrate the interior of both sides of the air outlet hood 13 respectively.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, when the fan 15 blows air to dissipate heat, the internal air force can automatically blow outward the multiple sets of movable flaps 23 inside the air outlet hood 13 to ensure normal air outlet passage. When the heat dissipation device is closed, the multiple sets of flaps 23 lose their thrust and can automatically droop down using gravity, and assist in sealing the inside of the air outlet hood 13 to prevent small animals from entering.

[0029] The two ends of the bottom left side of the side cover 3 are respectively fixed with fixing plates 18, and the left side of the fixing plate 18 is provided with a locking rod 17. The two ends of the top left side of the outer box 2 are respectively provided with connecting holes 16. The two ends of the top right side of the side cover 3 are respectively fixed with connecting feet 8. The two ends of the top of the outer box 2 are respectively fixed with connecting brackets 9. The connecting feet 8 and the interior of the connecting brackets 9 are hinged. The right side of the locking rod 17 passes through the interior of the fixing plate 18 and is threadedly connected to the connecting hole 16. A handle is fixed at the middle position of the bottom left side of the side cover 3.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, during internal maintenance and repair of the device, the two sets of locking rods 17 are rotated outward from the connecting hole 16 at the bottom left side of the side cover 3 to unlock the side cover 3. Then, the side cover 3 can be flipped upward using the hinge between the connecting foot 8 and the connecting frame 9 to facilitate convenient maintenance and repair of the internal components of the device.

[0031] A mounting bracket 1 is fixed to the bottom of the inner casing 2, and a heat dissipation pipe 4 is fixed inside the mounting bracket 1. Heat dissipation fins 5 are fixed to the outside of the heat dissipation pipe 4. An oil outlet pipe 6 is provided at the bottom left side of the mounting bracket 1. A pump 7 is installed and fixed at the top of the mounting bracket 1, and a return oil pipe 10 is installed and fixed at the output end of the pump 7.

[0032] Working principle: When this utility model is in use, the pump 7 starts and uses the oil extraction pipe 12 to draw the used hydraulic oil from the hydraulic oil tank 11 to the inside of the heat dissipation pipe 4. The heat inside the hydraulic oil is absorbed and discharged through the heat dissipation pipe 4 and the outer heat dissipation fins 5. At the same time, the two sets of fans 15 at the front end can be started to blow air onto the heat dissipation pipe 4 and the heat dissipation fins 5 to accelerate the heat dissipation efficiency. During the heat dissipation process, a filter screen 19 is inserted and installed at the front end of the fan 15 inside the air inlet shroud 14. The filter screen 19 can be used to filter and remove large-volume lint and other impurities in the external air drawn in, and to provide auxiliary dust prevention inside the device.

[0033] When the fan 15 starts to blow air to cool the internal heat dissipation pipes 4 and heat dissipation fins 5, the internal air force can automatically blow the multiple sets of movable flaps 23 inside the air outlet shroud 13 outward to ensure normal air outlet passage. When the heat dissipation device is closed, the multiple sets of flaps 23 lose their thrust and can automatically droop down using gravity, thus providing auxiliary sealing to the inside of the air outlet shroud 13.

[0034] Furthermore, during maintenance and repair of the device, by rotating the two sets of locking rods 17 outward from the connecting hole 16 at the bottom left side of the side cover 3 to unlock the side cover 3, the side cover 3 can be flipped upward using the hinge between the connecting foot 8 and the connecting frame 9, allowing for convenient maintenance and repair of the internal components of the device.
