Description

Technical Field

[0001] The invention relates to an oil-water separator for a new energy motor cooler and belongs to the field of new energy vehicles. Background Art

[0002] The cooling of motors and batteries in the prior art mainly relies on liquid cooling of antifreeze. Although the conductivity of antifreeze is low, the impurities in the antifreeze will increase during long-term use. At the same time, the water vapor from the outside will penetrate into the antifreeze due to thermal expansion and contraction, and the organic solvent in the antifreeze will evaporate, thereby increasing the water content and conductivity of the antifreeze, which will not only increase the risk of leakage, but also may cause electrochemical corrosion to the battery casing and motor mechanism. In addition, the water vapor after the antifreeze evaporates will also invade into the motor through the seams, causing corrosion and short circuit of electrical components. A cooling solution using oil cooling instead of liquid cooling is proposed in the prior art. However, like antifreeze, oil cooling will still have the problem of water vapor infiltration, and the evaporated water vapor and the water it brings will still corrode the battery casing, the electrical components of the motor and other items; the oil dehumidification in the prior art is only to set a breathing water absorber in the oil circuit, and rely on the self-evaporation of water vapor to separate the water through the high temperature of the oil when it is working. However, compared with the internal combustion engine, the normal operating temperature of the motor casing of the new energy electric vehicle is only about 80°C, which is difficult to reach the boiling point of water. Moreover, the entire oil circulation circuit is in a high-pressure environment, and the boiling point of water will be much higher than 100°C; therefore, the water separation efficiency of the solution relying on natural evaporation is low.

[0019] The beneficial effects of the present invention are:

[0020] The present invention can be attached to a bypass pipeline of oil circulation, and through a set of reciprocating breathing mechanisms, the oil input and output ends are closed by negative pressure driving. At the same time, the pressure in the oil circulation pot is reduced by negative pressure, so that part of the oil in the oil circulation pot is at a relatively low boiling temperature, so that the water in the oil evaporates quickly and is sucked into the silica gel particles by negative pressure and absorbed by the silica gel particles. In addition, the flow resistance of the silica gel particles is relatively large. Compared with natural convection driving, negative pressure driving can relatively efficiently achieve full contact between water vapor and silica gel particles, thereby improving the efficiency of moisture absorption.

[0021] The surge plate can prevent the vehicle from being impacted during the vehicle movement process, causing the engine oil to be filled into the dehumidifier at high speed, causing the engine oil to adhere to the surface of the silica gel, blocking moisture absorption and affecting the normal operation of the dehumidifier.

[0022] The adapter ring uses a single thread to fix the oil circulating pot. Because the oil circulating pot is affected by negative and positive pressures and needs to have a certain amount of elastic deformation, it can only be made of polymer materials. Compared with flange structures with a higher opening rate, polymer materials have better stability and higher strength when fixed with a single thread.

[0023] The third one-way valve is connected to the fixing ring of the metal structure, which can reduce the opening rate of the oil circulation pot and improve the strength; at the same time, the air pressure pipeline will often float due to changes in air pressure, so this connection method can increase the service life and reduce the possibility of damage to the oil circulation pot.

[0024] The bending of the bent portion changes the flow angle of the engine oil, increases the flow resistance, and reduces the splashing of the engine oil caused by the direct impact of the high-pressure engine oil pumped from the oil pump.

[0025] The guide protrusion is formed by a support plate. Compared with processing on the valve plate, processing the support protrusion on the valve plate will improve the bending resistance of the valve plate. After the bending resistance of the valve plate is improved, the sealing efficiency generated by the valve plate through its own elastic deformation will be reduced; using clamping fixation is convenient for replacement and maintenance, and the cost is lower than welding fixation.

[0026] An additional dehumidification structure is arranged inside the outer frame of the piston, which can not only reduce the humidity of the gas during the return air, but also prevent the condensation and accumulation of water vapor in the electromagnetic pump, occupying the compression volume of the electromagnetic pump and affecting the working efficiency of the electromagnetic pump.

[0027] Two groups of silica gel particles of different particle sizes are used in the first dehumidification box. The first group of silica gel particles with larger diameters have lower air flow resistance, which can make the gas evenly distributed. Then, the evenly distributed air is efficiently absorbed by the silica gel particles with smaller diameters.

[0028] The sliding sleeve can ensure the floating stability of the sliding shaft and ensure the consistent floating of each valve plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] When using, Figure 1 and Fig. 9, the oil-water separator is connected in parallel to the oil circulation main pipe near the oil pot through the first oil bypass pipe 36 and the second oil bypass pipe 38; in the default state, the oil pushes the first valve block 35-6 of the flow limiting valve 35 through the impact force of the circulation pump, so that the oil enters the oil circulation pot 1 through the oil inlet pipe 5; at the same time, the piston ring 40 in the piston outer frame 39 moves back to the top of the piston outer frame 39 under the mutual electromagnetic action of the electromagnetic winding 45 and the permanent magnet 42, so that a certain negative pressure is formed in the piston outer frame 39, and the negative pressure will close the third one-way valve 55, and transmit the negative pressure to the control valve mechanism through the main exhaust pipe 34, and the negative pressure makes the valve plate 13 is separated from the limiting protrusion 12 of the limiting ring 11, generating an air gap.

At the same time, the negative pressure in the oil circulation pot 1 will synchronously close the first one-way valve 37, and eventually the entire oil circulation pot 1 will be closed relative to the external environment and generate negative pressure. The negative pressure will cause the water mixed in the oil to evaporate based on the heating of its own temperature, and the water vapor generated by the evaporation will pass through the space between the guide protrusion 14-1 and the limiting protrusion 12. The air then passes through the air inlet 22 and enters the silica gel particles 57 in the partition net 27. Under the uniform flow of the silica gel particles 57 in the partition net 27, the water vapor will further pass through the partition net and enter the silica gel particles 57 outside the partition net. The air that has absorbed the moisture will enter the breathing chamber through the second one-way valve 33, and will be stored in the piston outer frame 39 after secondary drying of the silica gel particles 57 in the breathing chamber. After one reciprocating cycle, the piston ring 40 moves toward the top of the piston outer frame 39 driven by the electromagnetic force, so that a positive pressure is generated in the piston outer frame 39. During the increase of the positive pressure, the third one-way valve 5 is slowly opened. 5, and slowly close the second one-way valve 33. When the second one-way valve 33 is closed, the valve plate 13 will contact the limiting ring 11 again under the drive of the return spring 30, so that the entire first dehumidification box is sealed to prevent moisture from rebounding to the oil circulation pot 1. The positive pressure in the piston outer frame 39 will enter the oil circulation pot 1 through the main intake pipe 56 under the re-drying of the second dehumidification box. The positive pressure in the oil circulation pot 1 will open the first one-way valve 37 and the limiting valve 35 in turn. The oil in the oil circulation pot 1 will be discharged from the oil discharge pipe 4 under the joint positive pressure of the oil pump and the oil circulation pot 1, and return to the oil circulation pipeline.
