Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a cooling device for a hydraulic cylinder. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, the deceleration device can be omitted, there is no transmission gap, and the motion is smooth. Therefore, the hydraulic cylinder is widely used in various mechanical hydraulic systems.

[0003] After searching, a Chinese patent discloses a hydraulic cylinder cooling device (authorization announcement number: CN 218934927), including a cylinder body, a water cooling component is arranged on the outer side of the cylinder body, an ice cooling component is arranged on the upper side of the cylinder body, and air cooling components are fixedly installed on the front and rear sides of the water cooling component. The utility model can produce a water cooling effect after adding cold water by fitting the water cooling component with the outer wall of the hydraulic cylinder, and can receive ice cubes of the ice cooling component and receive and utilize the melted water, so that the cold effect can be recycled, the loss of the cold effect can be reduced, energy saving and resource saving can be achieved, the ice cooling component can produce ice cubes, and make the ice cubes contact the hydraulic cylinder, and the ice cooling effect can be produced by the low temperature of the ice cubes, and the air cooling component can produce cold wind with strong wind force, and the air cooling effect can be produced by blowing on the cylinder body, and the water cooling component, the ice cooling component and the air cooling component have a triple refrigeration effect, and the cooling capacity is strong, and the hydraulic cylinder can be cooled efficiently and quickly.

[0004] In actual application, this patented technology can cool the hydraulic cylinder with strong cooling capacity, and can cool the hydraulic cylinder efficiently and quickly. However, during use, since the above scheme is to place the hydraulic cylinder inside the circulation pipe and fix the hydraulic cylinder, but now the sizes of hydraulic cylinders are different, the above scheme cannot cool hydraulic cylinders of different sizes, thereby reducing the practicality of the device. At the same time, since the temperature of the ice cube itself is very low, and the ice cube in the above scheme is in direct contact with the high-temperature hydraulic cylinder, it will cause the cylinder body to cool down rapidly and change the molecules of the metal cylinder body, which can easily cause the cylinder body to rupture and damage. In addition, the viscosity of the hydraulic oil at low temperature will be too high, the self-priming ability of the hydraulic pump will decrease, the pressure loss of the hydraulic system will increase, and the power loss will increase.
