Problems solved by technology

However, due to the structural limitation of the oil cooling module, in order to save space, the distance between the oil drain channel and the rotor cavity is usually relatively close, and the high-pressure oil in the oil drain channel often directly enters the rotor cavity without being fully mixed with the low-pressure oil in the inlet channel, causing damage to the rotor. At the same time, because the flow direction of the high-pressure oil in the oil discharge channel is opposite to the flow direction of the oil in the rotor cavity, the two oils will produce strong hedging, and a large eddy current will be generated in the rotor cavity, which will not only easily cause cavitation, but also easily lead to Difficulty absorbing oil

Abstract

The invention discloses an improved engine oil cooling module housing. The housing is provided with an oil pump rotor cavity, an oil drain channel and an oil inlet channel. The outlet end of the oil drain channel is provided with an extending The oil baffle is in the shape of "J", and the bending direction of the tail of the oil baffle is consistent with the flow direction of the oil in the rotor cavity. Such a structure can make the high-pressure oil in the oil discharge channel blocked by the baffle, avoiding the high-pressure oil directly entering the rotor chamber, and must be fully mixed with the inlet oil at the bottom before entering the rotor chamber, thus reducing the impact of the high-pressure oil on the rotor; At the same time, the lower end of the partition is set as a curved structure whose direction is close to the flow direction of the oil in the rotor cavity, so that the direction of oil inlet can be guided to be consistent with the flow direction in the rotor cavity, which reduces hedging and reduces the risk of cavitation.

Description

Technical field [0001] The present invention relates to an improved oil cooling module housing. Background [0002] The pressure relief method of the oil pump outlet in the traditional oil cooling module usually adopts the internal drainage type, that is, 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 connected with the oil inlet channel through the oil discharge channel, the high-pressure oil returns to the oil inlet channel through the oil discharge channel, and the high-pressure oil and the low-pressure oil enter the rotor cavity together after being fully mixed (see Figure 1 ）。 However, due to the limitation of the oil cooling module structure, in order to save space, the distance between the oil discharge channel and the rotor cavity is usually relatively close, and the high-pressure oil of the oil discharge channel is often directly entered the rotor cavity w...
