Description

Technical Field

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

[0002] Hydraulic oil cooling devices in hydraulic equipment are key devices used to reduce the temperature of hydraulic oil. During the operation of a hydraulic system, hydraulic oil generates a large amount of heat due to pressure changes, friction, and flow. If the temperature is too high, it will affect the viscosity of the oil, reduce the lubrication effect, accelerate the wear of system components, and even lead to system failure.

[0003] In the prior art, such as Chinese Patent No. CN202322099350.5, this utility model relates to the field of hydraulic equipment technology and discloses a hydraulic oil cooling device for hydraulic equipment, including a cooling box and two cooling frames. A cooler is fixedly installed on the upper surface of the cooling box. Cold water inlet pipes and cold water outlet pipes are fixedly connected to the upper and lower sides of the cooling box, respectively. An S-shaped flow pipe is fixedly installed inside the cooling box, and the two ends of the S-shaped flow pipe are fixedly connected to the corresponding cold water inlet pipe and cold water outlet pipe, respectively. A water pump is fixedly installed on the outer wall of the cold water outlet pipe. Cooling fans are fixedly installed on the upper and lower sides of one side of each of the two cooling frames. In this utility model, by circulating the cooling water in the cooling box, the purpose of circulating cooling of the hydraulic oil can be achieved, thereby achieving efficient heat dissipation. At the same time, the effective use of the heat sink can further accelerate heat dissipation, resulting in more efficient heat dissipation.

[0004] While the above-mentioned solutions offer advantages such as high-efficiency heat dissipation, they also present certain heat dissipation efficiency issues in practical applications. Specifically, when the coolant flows inside the S-shaped flow tube, it exchanges heat with the high-temperature hydraulic oil in the radiator through the pipe, thereby carrying away the heat. However, because the hydraulic oil is relatively stationary in the radiator and has poor fluidity, it cannot make sufficient contact with the coolant in a timely manner, which limits the heat transfer efficiency. The lack of effective flow or disturbance of the hydraulic oil in the radiator reduces the heat exchange area between the hydraulic oil and the cooling medium, making the heat transfer process slow and ultimately resulting in low overall heat dissipation efficiency.

Detailed Implementation

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Example 1, please refer to Figure 1-5 This utility model provides a technical solution: a hydraulic oil cooling device for hydraulic equipment, comprising a device body 1, a cooling component, and a return component.

[0047] The cooling assembly includes: an oil tank 101 fixedly installed on the top of the device body 1 by multiple support columns; a first water inlet pipe 102 fixedly installed on the bottom right side of the oil tank 101; and a first valve 103 fixedly installed inside the first water inlet pipe 102.

[0048] A spiral copper pipe 104 is fixedly installed at the other end of the first water inlet pipe 102. The spiral copper pipe 104 is fixedly embedded inside the device body 1. A second water inlet pipe 105 is fixedly embedded at the top of the oil tank 101.

[0049] A motor 106 is provided on the top of the device body 1. A support 107 is fixedly sleeved on the outer surface of the motor 106. The bottom of the support 107 is fixedly installed on the top of the device body 1. A large gear 108 is fixedly sleeved on the outer surface of the output shaft of the motor 106.

[0050] Multiple rotating rods 109 are movably embedded in the top side of the device body 1. Each rotating rod 109 has a small gear 110 fixedly installed on its top. The small gears 110 mesh with the adjacent large gear 108. Multiple stirring blades 111 are fixedly installed on both sides of the multiple rotating rods 109. The stirring blades 111 are movably embedded in the inside of the device body 1.

[0051] The cooling assembly also includes: a third water inlet pipe 112 is fixedly embedded in the top of the device body 1, a water outlet pipe 113 is fixedly installed in the bottom of the device body 1, and a second valve 114 is fixedly installed inside the water outlet pipe 113.

[0052] In this embodiment, when the motor 106 is running, it can drive the large gear 108 to rotate through the output shaft. When the large gear 108 rotates, it can move the teeth of multiple small gears 110, thereby causing the small gears 110 to rotate, so as to transmit power to the rotating rod 109 through the small gears 110.

[0053] Example 2, as Figure 1-5 As shown, the reflux assembly includes: a first reflux pipe 2 is fixedly installed at the bottom end of the spiral copper tube 104, and the outer surface of the first reflux pipe 2 is fixedly embedded in the right side of the inside of the device body 1.

[0054] A pump 201 is fixedly installed at the other end of the first return pipe 2, and a second return pipe 202 is fixedly installed on the top side inside the pump 201. The other end of the second return pipe 202 is fixedly installed on the top side inside the oil tank 101.

[0055] In this embodiment, when the hydraulic oil flows from top to bottom inside the spiral copper tube 104, the pump 201 can be started to draw out the hydraulic oil inside the spiral copper tube 104 through the first return pipe 2 and inject it into the pump 201 through the first return pipe 2. The pump 201 then transfers the hydraulic oil for return.

[0056] Working principle: During use, personnel can first inject hot hydraulic oil into the oil tank 101 through the second water inlet pipe 105, and then inject coolant into the device body 1 through the third water inlet pipe 112. Afterwards, personnel open the first valve 103, allowing the hot hydraulic oil inside the oil tank 101 to enter the spiral copper tube 104 inside the device body 1 through the first water inlet pipe 102, allowing it to circulate from top to bottom within the spiral copper tube 104 to cool the hot hydraulic oil. Simultaneously, personnel can start the motor 106 through the power supply system of the motor 106 in the support member 107. During operation, the motor 106 can drive the output shaft to the large gear 108, and as the large gear 108 rotates, it can drive the small gear 110... The drive is transmitted through the rotating rod 109, which drives the stirring blade 111 to rotate inside the device body 1, agitating the coolant. The arrangement of the spiral copper tube 104 and the stirring blade 111 not only allows the hot hydraulic oil to flow from top to bottom within the spiral copper tube 104, but this spiral flow path also helps to increase the contact area between the hydraulic oil and the cooling medium, thereby improving the heat exchange efficiency and ensuring that the hot hydraulic oil is fully cooled during the flow. At the same time, it can drive the stirring blade 111 to rotate, which can effectively agitate the coolant. The agitation action can make the coolant contact the hot hydraulic oil more evenly, preventing the formation of a hot layer due to the temperature rise of the coolant and ensuring that the temperature of the coolant remains stable.

[0057] During use, when hydraulic oil circulates inside the spiral copper tube 104, personnel can start the pump 201 via its power supply system. During operation, the pump 201 draws hydraulic oil from inside the spiral copper tube 104 through the first return pipe 2 and transfers it to the pump 201. The hydraulic oil then flows back into the oil tank 101 through the second return pipe 202 for repeated cooling. When the coolant level inside the device body 1 is too high, personnel can open the second valve 114 to allow the coolant inside the device body 1 to flow out through the outlet pipe 113 for replacement. The design of the first return pipe 2 and the pump 201 ensures continuous flow of hydraulic oil within the spiral copper tube 104, forming a closed-loop circulation system. The pump 201 draws hydraulic oil from the copper tube through the first return pipe 2 and returns it to the oil tank 101 through the second return pipe 202. This circulating flow method ensures that the temperature of the hydraulic oil can be continuously controlled and reduced, improving the heat dissipation efficiency of the hydraulic oil and avoiding equipment failures that may be caused by excessively high oil temperature.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
