Hydraulic oil cooling structure

Abstract

The invention discloses a hydraulic oil cooling structure. The hydraulic oil cooling structure comprises a water tank and a heat exchange barrel. A liquid outlet pipe and a liquid return pipe are connected to the upper end and the lower end of the heat exchange barrel correspondingly. A cold liquid outlet and a hot liquid inlet are formed in the lower section of the side wall of one end of the water tank, a cold liquid inlet is formed in the upper section of the side wall of the other end of the water tank, and a hot liquid outlet is formed in the lower section of the side wall of the other end of the water tank. The cold liquid outlet communicates with the hot liquid inlet through a heat exchange pipe. The heat exchange pipe is spirally wound around the outer circumference wall of the heat exchange barrel in the axis direction of the heat exchange barrel. A corrugated plate divides the box into two parts is arranged in the box. The end portion of the end, away from the cold liquid outlet, of the corrugated plate is bent, then extends upwards and is connected with the inner wall of the part, close to the cold liquid inlet, of the box. Hydraulic oil in a high-temperature state flowsinto the heat exchange barrel from the liquid outlet pipe, and the purpose of temperature reducing and cooling of hydraulic oil is achieved through heat exchange between the heat exchange barrel andthe heat exchange pipe; and the cooled hydraulic oil returns to the hydraulic system again from the liquid return pipe, and accordingly continuous usage is convenient.

Description

technical field [0001] The invention relates to cooling equipment, in particular to a hydraulic oil cooling structure. Background technique [0002] Hydraulic equipment refers to the device that transmits pressure through hydraulic oil and is the carrier of the hydraulic system. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components and hydraulic oil. The function of hydraulic cylinder and hydraulic motor, the actuators of the hydraulic system, is to convert the pressure energy of the liquid into mechanical energy to obtain the required linear reciprocating motion or rotary motion. Hydraulic equipment has the characteristics of large transmission force, easy transmission and configuration, so it is widely used in industrial and civil industries. [0003] At present, the hydraulic oil used in hydraulic equipment mainly relies on natural cooling, and the cooling effect is relatively poor. Due to the in...

Problems solved by technology

[0003] At present, the hydraulic oil used in hydraulic equipment mainly relies on natural cooling, and the cooling effect is relatively poor. Due to the increase in the temperature of the hydraulic oil, the hydraulic equipment fails frequently, which increases the failure rate and causes the hydraulic equipment to work unstable.
