Thermal management module for vehicle and method of operating same

Abstract

The invention provides a thermal management module for a vehicle and a method of operating the same. According to the thermal management module for a vehicle, a plunger assembly which reciprocates inthe internal space of a module main body is adopted to control the flow of a fluid medium, and the plunger assembly can be statically sealed with the module main body at different parts. Therefore, compared with the dynamic seal of a rotary valve in the prior art, the static seal realized by the thermal management module for the vehicle has the advantages that the sensitivity to vibration is lower, the requirements on the performance of materials and processing parameters are lower, and the leakage risk is lower. The thermal management module for a vehicle adopts only one plunger assembly, sothat the overall structure is relatively simple, the required space is small, and the cost is low. The plunger assembly of the thermal management module for a vehicle is characterized in that at leastthe outer contour of the section, intercepted in the axial direction, of the plunger head is the curve with the preset curvature, so that the hydraulic pressure, acting on the plunger head, of a fluid medium is reduced, and therefore driving force for driving the plunger assembly is saved.

Description

technical field [0001] The invention relates to the field of vehicles, and more particularly relates to a thermal management module for a vehicle and a working method thereof. Background technique [0002] In the field of vehicles, thermal management modules are becoming more and more important whether in traditional pure engine drive systems, pure electric drive systems or hybrid drive systems. However, the existing thermal management modules usually use rotary valves etc. to control the flow of the fluid medium. The rotary valve and the outlet pipe in this thermal management module adopt a rotary sealing method, so there are the following disadvantages: [0003] 1. Very sensitive to vibration, easy to cause failure due to vibration; [0004] 2. High requirements on the performance and processing parameters of materials such as plastics; [0005] 3. There is a high risk of leakage in the shaft seal and interface seal; [0006] 4. Requires a relatively larger space; and ...
