Abstract
The invention discloses an improved engine oil cooling module shell, wherein an engine oil pump rotor cavity, an oil drainage channel and an oil inlet channel are arranged on the shell, an extended oil baffle plate is arranged at one side, close to the rotor cavity, of the outlet end of the oil drainage channel, the oil baffle plate is J-shaped, and the bending direction of the tail part of the oil baffle plate is consistent with the engine oil flow direction in the rotor cavity. The structure can lead the high-pressure oil in the oil drainage channel to be blocked by the baffle plate, and prevent the high-pressure oil from directly entering the rotor cavity and entering the rotor cavity after being fully mixed with the inlet oil below, thereby reducing the impact of the high-pressure oil on the rotor; simultaneously, the baffle lower extreme sets up to the direction and the rotor intracavity oil flow direction curved structure that is close, just can be unanimous for the flow direction with the rotor intracavity with the oil feed direction, has reduced the offset, reduces the cavitation erosion risk.
Description
Technical Field
The present invention relates to an improved oil cooling module housing.
Background
The pressure relief mode of the oil pump outlet in the traditional oil cooling module usually adopts an internal relief mode, namely when the outlet pressure of the oil pump exceeds the opening pressure of the pressure limiting valve, the pressure limiting valve is opened, the oil pump outlet is communicated with the oil inlet channel through the oil relief channel, high-pressure oil returns to the oil inlet channel through the oil relief channel, and high-pressure oil and low-pressure oil are fully mixed and then enter a rotor cavity (see figure 1). But because the restriction of machine oil cooling module structure, for saving space, it is near usually with the rotor chamber distance that the draining passageway, the high-pressure oil of draining passageway often does not have the low-pressure oil intensive mixing with the inlet passage just directly got into the rotor chamber, causes the huge impact to the rotor, simultaneously because the flow direction of high-pressure oil in the draining passageway is opposite with the flow direction of rotor intracavity oil, two strands of oil can produce strong clashing, produce great vortex in the rotor chamber, not only produce cavitation easily, lead to the oil absorption difficulty simultaneously easily. Therefore, a reasonable structure is required to ensure the reliability and stability of the operation of the product.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides an improved oil cooling module shell which can avoid the impact of high-pressure oil in an oil drainage channel on a rotor.
In order to solve the technical problems, the invention adopts the following technical scheme: the improved engine oil cooling module shell is provided with an engine oil pump rotor cavity, an oil drainage channel and an oil inlet channel, one side, close to the rotor cavity, of the outlet end of the oil drainage channel is provided with an extended oil baffle, the oil baffle is J-shaped, and the bending direction of the tail of the oil baffle is consistent with the engine oil flow direction in the rotor cavity.
Preferably, the width of the middle section of the oil drainage channel is larger than the width of the outlet end.
Preferably, the width of the outlet end of the oil drainage channel is smaller than that of the outlet end of the oil inlet channel.
Furthermore, a boss is arranged in the oil inlet channel, the boss divides the oil inlet channel into two parts to form a first oil inlet channel and a second oil inlet channel, the outlet end of the oil drainage channel is communicated with the first oil inlet channel, the outlet end of the first oil inlet channel is communicated with the second oil inlet channel, and the outlet end of the second oil inlet channel is communicated with the oil pump rotor cavity.
Preferably, the oil drainage channel is intersected with the first oil inlet channel in a herringbone mode.
Preferably, the width of the first oil inlet channel outlet end is less than the width of the second oil inlet channel outlet end.
The invention has the beneficial effects that: because one side that the exit end of draining passageway is close to the rotor chamber is equipped with the fender oil baffle of extension, keep off the oil baffle and be "J" shape, the crooked direction of keeping off oil baffle afterbody is unanimous with the machine oil flow direction in the rotor chamber. The structure can lead the high-pressure oil in the oil drainage channel to be blocked by the baffle plate, and prevent the high-pressure oil from directly entering the rotor cavity and entering the rotor cavity after being fully mixed with the inlet oil below, thereby reducing the impact of the high-pressure oil on the rotor; simultaneously, the baffle lower extreme sets up to the direction and the rotor intracavity oil flow direction curved structure that is close, just can be unanimous for the flow direction with the rotor intracavity with the oil feed direction, has reduced the offset, reduces the cavitation erosion risk.
In a further technical scheme, a boss is arranged in the oil inlet channel, the boss divides the oil inlet channel into two parts, engine oil of the oil inlet is divided into two branch flows which enter from the two channels respectively, the engine oil of the oil drainage channel is only in butt-joint with the engine oil in the first oil inlet channel, but has no influence on the engine oil in the second oil inlet channel, and due to the reduction of the butt-joint space, the butt-joint strength is obviously weakened, and the generated eddy phenomenon is correspondingly weakened. The engine oil after the first mixing is further mixed with the engine oil in the second oil inlet channel before entering the rotor cavity, and the influence of the vortex is further reduced, so that the phenomena that the engine oil pump is difficult to absorb oil, the flow is unstable, the rotor generates cavitation erosion and the like are avoided.
