Heat dissipation hydraulic cylinder

Abstract

The invention provides a heat dissipation hydraulic cylinder. The heat dissipation hydraulic cylinder comprises a cylinder body, a cylinder head, a cylinder bottom, a front flange, a rear flange, a piston and a piston rod. A heat dissipation device and a temperature sensing device are arranged on the portion, between the front flange and the rear flange, of the outer side of the cylinder body. The temperature sensing device is arranged on the heat dissipation device. The heat dissipation device comprises a cooling ring and cooling fins located in the cooling ring. The cooling ring comprises an inner ring, an outer ring, a side wall, a water inlet and a water outlet. The cooling fins are arranged on the inner side of the inner ring and the inner side of the outer ring in a staggered mode. The water inlet and the water outlet are formed in the outer side of the outer ring. After the heat dissipation device is installed, the overall dimension of the hydraulic cylinder is not increased, and no additional space is occupied. Production and machining are easy, installation is convenient, the heat dissipation effect is good, an operator can know the temperature of hydraulic oil in the hydraulic cylinder at any time, and the service life of the hydraulic cylinder is prolonged.

Description

technical field [0001] The invention relates to a hydraulic cylinder, in particular to a heat dissipation hydraulic cylinder. Background technique [0002] The heating of the hydraulic system is a major problem in the hydraulic system. To solve this problem, a radiator is often installed in the circuit of the hydraulic system to cool the hydraulic oil to achieve the purpose of cooling the entire system. However, in the hydraulic cylinder, the piston and the cylinder block The largest heat source caused by the back and forth friction of the contact surface. Due to the tight contact surface, the hydraulic oil cannot enter it, resulting in difficulty in heat dissipation and heat accumulation. The increase in heat will cause the aging of the sealing ring and the accelerated wear of the piston. The structure of the existing heat dissipation oil cylinder heat dissipation device is complicated, which brings difficulties to the production and processing of the oil cylinder, and the ...

[0002] The heating of the hydraulic system is a major problem in the hydraulic system. To solve this problem, a radiator is often installed in the circuit of the hydraulic system to cool the hydraulic oil to achieve the purpose of cooling the entire system. However, in the hydraulic cylinder, the piston and the cylinder block The largest heat source caused by the back and forth friction of the contact surface. Due to the tight contact surface, the hydraulic oil cannot enter it, resulting in difficulty in heat dissipation and heat accumulation. The rise of heat will cause the aging of the sealing ring and the accelerated wear of the piston.

The complex structure of the existing heat dissipation oil cylinder heat dissipation device brings difficulties to the production and processing of the oil cylinder, and the heat dissipation effect is not good
