Embodiment Construction

[0021] like Figures 1 to 3 shown

[0022] The novel hydraulic oil cooling device 5 includes a built-in check valve 55, an air-cooled cooling part, a hydraulic filtering part, a throttle valve 51, a solenoid valve 54 and a safety valve 56. The hydraulic filtering part, the air cooling The heat dissipation part, the built-in check valve 55 and each component adopt an integrated one-piece structure ( figure 2 Can only show the radiator 52 of an air-cooled radiating part and the filter element 53 of a hydraulic filter part, and its back side also has a radiator 52 and filter element 53).

[0023] The air-cooled heat dissipation part and the hydraulic filter part constitute the main channel for heat dissipation and filtration of the oil supply liquid. The air-cooled heat dissipation part includes two radiators 52, and the two radiators 52 are arranged in parallel. The device 52 is also provided with a fan, and the air outlet of the fan is aimed at the air-cooled heat sink.

Abstract

The invention provides a novel hydraulic oil heat dissipation device. The novel hydraulic oil heat dissipation device comprises a built-in one-way valve, an air cooling heat dissipation portion and ahydraulic filtering portion. Oil liquid flows out of a rod cavity of an oil cylinder, sequentially passes through the air cooling heat dissipation portion and the hydraulic filtering portion and finally flows into an oil tank. The air cooling heat dissipation portion comprises multiple heat dissipaters. The multiple heat dissipaters are in parallel connection. The hydraulic filtering portion is internally provided with multiple filter elements. The multiple filter elements are in series connection and different in filter precision. The two ends of the built-in one-way valve are in parallel connection to an inlet of the air cooling heat dissipation portion and an outlet of the hydraulic filtering portion. The oil liquid flows out of the rod cavity of the oil cylinder, sequentially passes through the air cooling heat dissipation portion and the hydraulic filtering portion of the novel hydraulic oil heat dissipation device and finally flows into the oil tank, and heat dissipation and filtration of the oil liquid are completed.

Description

technical field [0001] The invention relates to a novel hydraulic oil cooling device. Background technique [0002] At present, radiators commonly used in the construction machinery industry adopt the principle of air cooling, that is, high-temperature hydraulic oil takes away a large amount of heat through air flow to achieve the purpose of cooling high-temperature hydraulic oil. However, the heat dissipation efficiency of the existing hydraulic oil cooling device is low, and it is increasingly unable to meet the needs of construction machinery. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel hydraulic oil cooling device with reasonable structure and high degree of integration. [0004] In order to solve the above technical problems, the present invention provides a novel hydraulic oil cooling device; [0005] Including built-in check valve, air-cooled radiator and hydraulic filter; [0006] The oil f...
