Problems solved by technology

However, the sealing ring used in the piston valve is made of rubber material, which is easily deformed or damaged under the extrusion of the movable valve core. Therefore, after long-term use, the sealing performance of the coolant channel is easily reduced, and internal leakage may occur. It needs to be replaced with a new sealing ring to continue to use, which will affect the use

Embodiment Construction

[0027] see Figure 1 to Figure 5 As shown, the flow control device 100 can be applied to heat exchange systems, such as vehicle air-conditioning systems or household air-conditioning systems, etc. Specifically, the flow medium controlled by the flow control device can be water, a mixed liquid of water and other liquids Or other cooling liquids with thermal conductivity, the flow control device controls the distribution of the flow medium and enables the flow medium to exchange heat with other working media of the heat exchange system, and then controls the outlet flow rate of the medium distributed by the flow control device The flow medium of the flow path of the heat exchange system can improve and optimize the control performance of the flow path of the heat exchange system.

[0028] The flow control device 100 can be used for new energy vehicle air conditioners such as HVAC, battery cooling or battery heating systems. Through the setting of the multi-pass structure of the ...

Abstract

The invention discloses a flow control device used for a vehicle heat exchange system and a manufacturing method of the flow control device. The flow control device at least comprises a shell, a valve element assembly and a control part; an inlet pipeline, a first outlet pipeline and a second outlet pipeline of the shell are relatively fixed with a distribution body, the inlet pipeline, the first outlet pipeline and the second outlet pipeline are sealed with the distribution body, the bottom side of a second valve piece and a limiting convex part in the shell are oppositely arranged, the bottom side of the second valve piece and a first valve piece are in seal contact, the inlet pipeline, the first outlet pipeline and the second outlet pipeline can be arranged in a separated manner, and according to needs, the inner diameter sizes of the inlet pipeline and the outlet pipelines can be conveniently adjusted.

Description

technical field [0001] The invention relates to a flow control device in the field of heat exchange. Background technique [0002] The electric vehicle thermal management system includes a coolant circulation system, which is composed of heat converters, power electronics, drive motors, on-board chargers, water storage pots, electric water pumps, reversing valves, high-temperature areas of cooling water tanks, high-voltage PTCs, and air-conditioning radiators , the reversing device is connected through pipeline circulation, which can be used to switch the flow direction of the coolant; for example, a hybrid vehicle usually adds a PTC heating device to make up for the lack of engine waste heat. At this time, it may be necessary to switch the coolant to the PTC heating device. In the process of switching the PTC heating device, it is also necessary to use a reversing valve to switch the flow direction of the coolant. [0003] At present, coolant reversing devices are widely u...
