Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil cooling technology, and in particular to a hydraulic oil cooling device for hydraulic equipment. Background Technology

[0002] Hydraulic oil cooling in hydraulic equipment refers to the process of reducing the temperature of the hydraulic oil through a cooling system to ensure the stable operation of the hydraulic system. During operation, the hydraulic oil generates heat due to friction and pressure loss. If the temperature is too high, it can lead to a decrease in oil viscosity, weakened lubrication performance, aging of seals, and even system failure. Therefore, the cooling system is a crucial component of hydraulic equipment.

[0003] Hydraulic oil cooling devices include air cooling and water cooling, with water cooling being more effective than air cooling. However, water cooling devices have the following drawbacks: installing a water cooling device in the hydraulic system's oil circuit requires altering the system's circuitry to allow the hydraulic oil to pass through the cooling device's interior for cooling. This means the cooling device also has to withstand the pressure of the flowing hydraulic oil. Furthermore, this type of water cooling device is cumbersome to install and is unsuitable for hydraulic systems that did not originally have a water cooling system and required retrofitting. Therefore, this invention proposes a hydraulic oil cooling device for hydraulic equipment. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a hydraulic oil cooling device for hydraulic equipment is disclosed, comprising a first clamping plate 1, a second clamping plate 2, and a water tank 3. The first clamping plate 1 and the second clamping plate 2 are both hollow inside. The first clamping plate 1 and the second clamping plate 2 are provided with a plurality of semi-circular grooves 8 at equal intervals on adjacent sides for inserting hydraulic oil pipes. A connecting pipe 4 connects the first clamping plate 1 and the second clamping plate 2. A pump body 5 connecting the first clamping plate 1 and the water tank 3 is fixed on the outer wall of the water tank 3. A return water pipe 6 is connected to the second clamping plate 2 and the water tank 3. Both sides of the first clamping plate 1 and the second clamping plate 2 are provided with docking components 7, and the first clamping plate 1 and the second clamping plate 2 are fixedly connected by the docking components 7. A cooling component 9 is installed on the side wall of the water tank 3, and a water inlet 10 is provided on the top wall of the water tank 3.

[0023] The top of the water inlet 10 is connected to a sealing cap 11 via a threaded connection.

[0024] Water can be added to the water tank 3 through the water inlet 10, and then the sealing cap 11 can be screwed onto the water inlet 10 to seal the inside of the water tank 3.

[0025] A water inlet pipe 51 is fixedly connected between the water inlet of the pump body 5 and the water tank 3, and a drain pipe 52 is fixedly connected between the water outlet of the pump body 5 and the first clamping plate 1.

[0026] The pump body 5 can draw water out of the water tank 3 and discharge it into the first clamping plate 1 through the drain pipe 52. The water entering the first clamping plate 1 will enter the second clamping plate 2 along the connecting pipe 4. The water entering the second clamping plate 2 will flow back to the water tank 3 along the return water pipe 6, thereby realizing the circulation of cooling water.

[0027] The cooling assembly 9 includes a semiconductor cooling chip 91 fixed to the outer wall of the water tank 3. The cooling side of the semiconductor cooling chip 91 is attached to the outer wall of the water tank 3, and a plurality of heat-conducting plates 92 are fixed to the cooling side of the semiconductor cooling chip 91. The plurality of heat-conducting plates 92 extend through the side wall of the water tank 3 into the interior of the water tank 3. A plurality of heat-dissipating plates 93 are fixedly connected to the heat-dissipating side of the semiconductor cooling chip 91.

[0028] The semiconductor cooling chip 91 can cool the cooling plate 92, thereby using the cooling plate 92 to cool the water inside the water tank 3, so that the pump body 5 can draw out the cooling water inside the water tank 3.

[0029] A cooling fan 94 is fixedly connected to several heat sinks 93 on the side away from the semiconductor cooling chip 91.

[0030] By setting up a cooling fan 94, the heat dissipation effect on the heat dissipation side of the thermoelectric cooler 91 can be improved, thereby ensuring that the thermoelectric cooler 91 can operate normally.

[0031] The docking assembly 7 includes a first side plate 71 fixed to the side of the first clamping plate 1 and a second side plate 72 fixed to the side of the second clamping plate 2. A plug 74 is fixed on the lower surface of the first side plate 71. A plug hole 73 for the plug 74 to pass through is opened in the middle of the second side plate 72. A groove 75 is opened on the side of the plug 74 away from the first clamping plate 1. A spring 76 is fixedly connected to the inner wall of the groove 75. A locking tooth 77 is fixedly connected to the other end of the spring 76. The end of the locking tooth 77 away from the spring 76 is engaged with the lower surface of the second side plate 72.

[0032] The bottom of the tooth 77, away from the spring 76, has a sloping design.

[0033] When assembling the first clamping plate 1 and the second clamping plate 2, the inserts 74 on the two first side plates 71 are simultaneously inserted into the insertion holes 73 in the middle of the two second side plates 72. As the inserts 74 pass through the insertion holes 73, the retaining teeth 77 are pressed back into the grooves 75. Once the retaining teeth 77 have completely passed through the insertion holes 73, the spring 76 pushes the retaining teeth 77 out of the grooves 75, causing the retaining teeth 77 to engage with the lower surface of the second side plates 72. This achieves a fixed connection between the first side plates 71 and the second side plates 72, thus completing the fixed connection between the first clamping plate 1 and the second clamping plate 2. During disassembly, the retaining teeth 77 are pushed back into the grooves 75. After the retaining teeth 77 disengage from the lower surface of the second side plates 72, the inserts 74 are pulled out of the insertion holes 73, thus separating the first side plates 71 and the second side plates 72, thereby achieving the separation between the first clamping plate 1 and the second clamping plate 2. The beveled design of the retaining teeth 77 makes it easier for them to be pushed back into the grooves 75.

[0034] In this embodiment, both the first clamping plate 1 and the second clamping plate 2 are made of metal, resulting in better cooling performance.

[0035] Working principle: First, multiple oil pipes are clamped into the semi-circular grooves 8 on the surface of the first clamping plate 1. Then, the second clamping plate 2 is fastened onto the surface of the first clamping plate 1, so that the semi-circular grooves 8 on the second clamping plate 2 are also clamped onto the surface of the oil pipes. The first clamping plate 1 and the second clamping plate 2 are then connected and fixed by the docking assembly 7. In use, the pump body 5 and the semiconductor cooling chip 91 are started. The semiconductor cooling chip 91 cools the water in the water tank 3. Then, the pump body 5 pumps the water in the water tank 3 into the first clamping plate 1 and the second clamping plate 2. The cooled first clamping plate 1 and the second clamping plate 2 cool the hydraulic oil in the oil pipes. The water after heat exchange returns to the water tank 3 along the return water pipe 6 to continue to be cooled.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
