Automatic temperature control dual cooling system

Abstract

The invention relates to an automatic temperature control dual cooling system. A blower housing is mounted at the rear end of the upper end surface of an oil tank. At least one blower is mounted on the inner side, facing the oil tank, of the blower housing. A water-cooled cooling pipeline is arranged on the upper end surface of the oil tank between an oil supply power source and the blower housing. A cooler communicates with the oil tank after connected in series with oil pipes in the water-cooled cooling pipeline. Output ends of three temperature sensors are connected with an input-output connector of a central control module. The input-output connector of the central control module is connected with control ends of a circulation oil power source and a circulation water power source. Cold air is sucked from the upper end surface of the oil tank by the blower, heat of other hydraulic components on the upper end surface of the oil tank can be taken away in air flowing, the water-cooled cooling pipeline is arranged on the upper end surface of the oil tank, whether an air-cooled way or a water-cooled way is put into use or not is determined through the three temperature sensors, and therefore, reduction of the temperature of oil is ensured, and the operation safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of improving the heat dissipation structure of oil in a hydraulic station, in particular to a double heat dissipation system with automatic temperature control. Background technique [0002] In some heavy-duty hydraulic systems or hydraulic systems with frequent movements, the temperature of the oil is high. In order not to affect the stability and safety of its work, the oil must be cooled. The existing heat dissipation structures include air cooling and water cooling. Among them, air cooling has the advantages of simple structure and no need for auxiliary equipment, while water cooling has the advantages of good heat dissipation and faster cooling, so some manufacturers combine air cooling and water cooling, but the optimization is insufficient, resulting in the defects of the two not being improved. , such as: the existing air-cooled structure is: including the fan housing 4, the radiator 3 and the circul...

[0002] In some heavy-duty hydraulic systems or hydraulic systems with frequent movements, the temperature of the oil is high. In order not to affect the stability and safety of its work, the oil must be cooled. The existing heat dissipation structures include air cooling and water cooling. Among them, air cooling has the advantages of simple structure and no need for auxiliary equipment, while water cooling has the advantages of good heat dissipation and faster cooling, so some manufacturers combine air cooling and water cooling, but the optimization is insufficient, resulting in the defects of the two not being improved. , such as: the existing air-cooled structure is: including the fan housing 4, the radiator 3 and the circulating oil power source 10, all of which are installed on the upper surface of the fuel tank 1, the fan housing is installed towards the inner side of the fuel tank, and the fan housing is facing towards the At least one fan 7 is installed on the outside of the oil tank. After the circulating oil power source draws the oil out of the oil tank, it is transported to the radiator through the inlet 8, and the fan sucks in the air from the side of the oil tank and blows it out to the radiator. The temperature of the oil at the place drops, and then the cooled oil returns to the oil tank from outlet 1. Since the radiator is located above the oil tank, the cold air sucked by the outside fan performs heat exchange with the radiator, and the hot air is blown out toward the top of the oil tank. , not only has an impact on other hydraulic components on the upper end of the oil tank, but also the heat dissipation effect of the separate fan needs to be improved. At the same time, the fan in the air cooling keeps rotating at a high speed, and it still maintains a constant speed when the oil temperature changes, wasting energy
