Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to a high-efficiency hydraulic cooler for aluminum profiles. Background Technology

[0002] During the extrusion and rolling processes of aluminum profiles, the hydraulic system, as the core power source, needs to operate under continuous high load. However, the temperature of the hydraulic oil will continue to rise during long-term operation due to frictional heat generation and energy loss. High temperature can lead to a decrease in hydraulic oil viscosity, deterioration of lubrication performance, and even cause failures such as aging of seals and system leakage, which seriously affect the production efficiency and product qualification rate of aluminum profiles.

[0003] Currently, traditional hydraulic cooling machines for aluminum profiles use relatively simple cooling methods. Air cooling is greatly affected by ambient temperature and has poor heat dissipation in high-temperature environments. Although water cooling has a better cooling effect, the cooling water is often difficult to recycle, resulting in a waste of water resources. Furthermore, the unstable cooling water temperature affects the heat exchange efficiency. Based on this, a high-efficiency hydraulic cooling machine for aluminum profiles is proposed for improvement. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency hydraulic cooler for aluminum profiles, including a box body, a heat dissipation chamber is provided in the center of the upper part of the box body, air ducts are symmetrically provided on both sides of the upper part of the box body, a water storage chamber is provided in the lower part of the box body, a cooling tower is fixedly connected to one side of the box body, the interior of the air ducts is connected to the interior of the cooling tower, and the lower part of the cooling tower is connected to the interior of the water storage chamber through a return water chamber;

[0006] The housing includes a cooling mechanism. A water pump is fixedly installed at the top of the housing. A water pump input end is fixedly connected to a water suction pipe. One end of the water suction pipe extends into the interior of the water storage chamber. A first water delivery pipe is fixedly connected to the output end of the water pump. One end of the first water delivery pipe extends into the interior of the heat dissipation chamber. A second water delivery pipe is connected to one end of the interior wall of the heat dissipation chamber. One end of the second water delivery pipe passes through the interior wall of the heat dissipation chamber and extends into the interior of the cooling tower. A water distribution cylinder is connected to the end of the second water delivery pipe extending into the interior of the cooling tower.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. This utility model utilizes a spiral cooling pipe to extend the residence time of hydraulic oil in the heat dissipation chamber, and works in conjunction with a heat pipe and heat dissipation fins to accelerate the transfer of heat to the air in the air duct; at the same time, the cooling tower and the fan work together to not only enhance the heat exchange efficiency of the heat dissipation fins through air convection, but also exchange heat with water droplets in the cooling tower to reduce the water temperature, forming a closed loop of dual heat dissipation for hydraulic oil and cooling water.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-4 This is the first embodiment of the present invention, which provides an efficient hydraulic cooling machine for aluminum profiles, including a box body 1, a heat dissipation chamber 11 is provided in the center of the upper part of the box body 1, air ducts 12 are symmetrically provided on both sides of the upper part of the box body 1, a water storage chamber 13 is provided in the lower part of the box body 1, a cooling tower 2 is fixedly connected to one side of the box body 1, the interior of the air ducts 12 is connected to the interior of the cooling tower 2, and the lower part of the cooling tower 2 is connected to the interior of the water storage chamber 13 through a return water chamber 21.

[0023] The housing 1 includes a cooling mechanism 4. A water pump 41 is fixedly installed at the top of the housing 1. A water pump 42 is fixedly connected to the input end of the water pump 41. One end of the water pump 42 extends into the water storage chamber 13. A first water supply pipe 43 is fixedly connected to the output end of the water pump 41. One end of the first water supply pipe 43 extends into the heat dissipation chamber 11. A second water supply pipe 44 is connected to one end of the inner wall of the heat dissipation chamber 11. One end of the second water supply pipe 44 passes through the inner wall of the heat dissipation chamber 11 and extends into the cooling tower 2. A water distribution cylinder 45 is connected to the end of the second water supply pipe 44 that extends into the cooling tower 2. Several drip nozzles 46 are threadedly connected to the bottom end of the water distribution cylinder 45.

[0024] A fan 47 is fixedly installed at the top of the cooling tower 2. A spiral cooling pipe 31 is provided on the inner wall of the heat dissipation chamber 11. An oil inlet pipe 3 is fixedly connected to one end of the spiral cooling pipe 31, and an oil outlet pipe 32 is fixedly connected to the other end of the spiral cooling pipe 31.

[0025] Several heat pipes 48 are fixedly connected to the surface of the spiral cooling pipe 31. One end of each heat pipe 48 penetrates the inner wall of the heat dissipation chamber 11 and extends into the air duct 12. Several heat dissipation fins 49 are connected to the surface of each heat pipe 48.

[0026] During use, the hydraulic oil to be cooled enters the spiral cooling pipe 31 in the heat dissipation chamber 11 through the oil inlet pipe 3, flows along the spiral path and releases heat. The heat conduction pipe 48 on the surface of the spiral cooling pipe 31 extends to the air duct 12, and the heat of the hydraulic oil is conducted to the heat conduction pipe 48. At the same time, the heat dissipation fins 49 on the heat conduction pipe 48 expand the heat dissipation area and accelerate the heat dissipation.

[0027] The water pump 41 is started to pump the cooling water from the water storage chamber 13 to the heat dissipation chamber 11, where it comes into contact with the outer wall of the spiral cooling pipe 31 and absorbs the heat conducted by the hydraulic oil. The temperature rises and the heated cooling water flows into the water distribution cylinder 45 in the cooling tower 2 through the second water supply pipe 44, and is evenly sprayed into water droplets through the drip nozzle 46.

[0028] Next, the fan 47 is started to draw air into the cooling tower 2, which drives the air in the air duct 12 to flow faster. Outside air enters the air duct 12 through the opening of the air duct 12 and flows at high speed through the heat dissipation fins 49 and heat pipes 48. When the air flows through the heat dissipation fins 49, it carries away the heat on the surface of the fins through convection heat exchange, which indirectly reduces the temperature of the spiral cooling pipe 31 and achieves the initial cooling of the hydraulic oil.

[0029] Air continues to flow into the interior of cooling tower 2, where it exchanges heat with water droplets, absorbing heat from the water droplets and lowering the water temperature. The air, having absorbed heat, is then discharged from the top of cooling tower 2 by fan 47. At the same time, the cooled water at the bottom of cooling tower 2 flows back to water storage chamber 13 through return water chamber 21, thus achieving dual heat dissipation for both hydraulic oil and cooling water.

[0030] This design utilizes the spiral cooling pipe 31 to extend the residence time of hydraulic oil in the heat dissipation chamber 11, and works with the heat pipe 48 and heat dissipation fins 49 to accelerate the transfer of heat to the air in the air duct 12. At the same time, the cooling tower 2 and the fan 47 work together to not only enhance the heat exchange efficiency of the heat dissipation fins 49 through air convection, but also exchange heat with water droplets in the cooling tower 2 to reduce the water temperature, forming a closed loop of dual heat dissipation for hydraulic oil and cooling water. Compared with the traditional single cooling method, the heat dissipation efficiency is significantly improved, and the cooling water is recycled to avoid water waste.

[0031] Reference Figures 1-4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the box body 1 also includes a stirring mechanism 5, and an impeller 51 is provided on the inner wall of one end of the water pumping pipe 42 that extends into the water storage chamber 13.

[0032] A fixed plate 53 is fixedly connected to the inner wall of the water storage chamber 13, and a drive shaft 52 is fixedly sleeved inside the impeller 51.

[0033] One end of the drive shaft 52 is rotatably connected to one side of the fixed plate 53, and several stirring blades 54 are connected to the surface of the drive shaft 52.

[0034] During use, when the water pump 41 draws water from the water storage chamber 13 through the water pipe 42, the water flows at high speed through the impeller 51, which drives the impeller 51 to rotate. The impeller 51 transmits power through the transmission shaft 52, which drives the stirring blade 54 to rotate at a constant speed in the water storage chamber 13 to stir the cooling water.

[0035] The rotation of the stirring blade 54 mixes the hot and cold water, ensuring that the cooling water pumped by the water pump 41 is at a uniform temperature, thereby improving the heat exchange efficiency in the heat dissipation chamber 11. At the same time, it does not require a separate drive source and only relies on the kinetic energy of the water flow when the water pump 41 is pumping water, thus not increasing the power consumption of the equipment and saving energy costs.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
