Abstract

The invention discloses an oil cylinder device dissipating heat automatically. The oil cylinder device dissipating heat automatically comprises two oil cylinders, a heat sink and a temperature control system, wherein each oil cylinder comprises an oil cavity arranged in the axial direction, a piston rod assembly movably arranged in the oil cavity in the axial direction, and an oil delivery tube communicating with the oil cavity; the heat sink is provided with a caching cavity; the oil cavities of the two oil cylinders communicate with the caching cavity through the oil delivery tubes; the temperature control system is used for regulating temperature of hydraulic oil, and comprises a temperature sensor, a refrigerating unit and a temperature controller; the temperature sensor is used for monitoring the temperature of the hydraulic oil; the refrigerating unit is used for further reducing the temperature of the hydraulic oil; the temperature controller is used for controlling the temperature of the hydraulic oil; the refrigerating unit is arranged on the heat sink; and a control switch which controls starting / closing of the refrigerating unit and the temperature sensor are electrically connected with the temperature controller. By the structure in the oil cylinder device dissipating heat automatically, the temperature of the hydraulic oil can be reduced quickly, and can be always below a set temperature, running stability of the oil cylinders is guaranteed, and the service lives of the oil cylinders are prolonged.

Description

technical field

[0001] The invention relates to a self-radiating oil cylinder device, which belongs to the field of oil cylinder structure design. Background technique

[0002] With the general enhancement of health awareness, more and more people are keen on sports and fitness. According to statistics, 1 out of 8 people in the United States is exercising. Take gyms as an example: there are more than 17,800 gyms in the United States, which means that every 10,000 Americans own a gym on average, while in China, an average of 1 million people own a gym. Take treadmills as an example: the United States has a population of 281 million, and the annual sales volume of treadmills is 3 million units; South Korea has a population of 46 million, and the annual sales volume is 1 million units; while my country has a population of 1.3 billion, and the annual sales volume is only 300,000 units. This shows how huge the fitness industry market in our country is, and the development of th...
