Problems solved by technology
[0003] When the existing hydraulic machinery dissipates heat, one is to directly act on the hydraulic oil, so that the hydraulic oil enters the hydraulic machinery in batches to complete the hydraulic work, and the hydraulic oil can work at intervals, thereby reducing the time for the hydraulic oil to have sufficient heat dissipation and reducing the Its internal heat, this method needs to consume additional energy, and the other is to indirectly cool the hydraulic oil through the cooling effect of water. After long-term use, the temperature of the water will increase, and the cold water needs to be replaced in time. inconvenient

The invention discloses a heat dissipation device of a hydraulic machine. The heat dissipation device comprises an annular cylinder, a plurality of open cylinders are evenly distributed on the outer side of the annular cylinder in the circumferential direction, the multiple open cylinders are sequentially connected with fan-shaped cavities end to end, and square pipes are connected between the open cylinders and the annular cylinder. The middle of each open cylinder communicates with an annular cavity with the diameter being larger than that of the open cylinder. According to the heat dissipation device of the hydraulic machine, the outer side of the fixed section of the hydraulic machine is sleeved with the annular cylinder, when the device is used on a moving machine, due to the fact that the moving machine can vibrate a lot, the generated vibrations enable a pressing disc to generate inertia and move downwards, and then the pressing disc can downwards press water in the open cylinders into the annular cylinder through the corresponding square pipes. The water with the heat being absorbed in the annular cylinder is pushed to go upwards and then a transverse pipe, and finally the water falls off onto the top of the pressing disc to generate further downward pressure to the pressing disc. Through the circulation, the water absorbing heat in the annular cylinder can be replaced into the cooled water in the open cylinders quickly, and in the process that the water absorbing heat falls off into the annular cylinder, rapid cooling can be achieved.
Description
technical field [0001] The invention belongs to the technical field of auxiliary devices for hydraulic equipment, and in particular relates to a cooling device for hydraulic machinery. Background technique [0002] Hydraulic pressure is a term in the mechanical industry and the electromechanical industry. Hydraulic pressure can be used as a power transmission method to become a hydraulic transmission. Hydraulic pressure can also be used as a control method, which is called hydraulic control; hydraulic transmission uses liquid as the working medium, and uses the pressure energy of the liquid to transmit power; hydraulic control uses pressure liquid as the control signal transmission method; it is composed of hydraulic technology The control system is called the hydraulic control system. Hydraulic control usually includes hydraulic open-loop control and hydraulic closed-loop control. Hydraulic closed-loop control is also hydraulic servo control, which constitutes a hydrauli...
