Problems solved by technology

[0003] At present, the coolant reversing device is widely used in the hybrid and pure electric vehicle industries. However, after the reversing device is used for a long time, the sealing performance of the coolant flow channel may form internal leakage due to loose parts, which will affect the use.

Abstract

The invention discloses a flow control device for a heat exchange system. The device comprises a movable valve piece, a transmission piece and an elastic piece, wherein a first valve piece and the transmission piece are assembled, the flow control device is provided with a mounting area located between the first valve piece and the transmission piece, the elastic piece is located in the mounting area, a limiting stop part of the flow control device is located on the outer side of the elastic piece in the radial direction, and along the vertical direction where the central axis of the elastic piece locates, the first end part of the elastic piece is in butt joint with a first pressure bearing surface of the first valve piece, and the second end part of the elastic piece is in butt joint with the second pressure bearing surface of the transmission piece. According to the device, the elastic piece which is not easy to fall off is arranged so as to press downwards the movable valve piece,the dynamic sealing performance between the movable valve piece and a matched part is improved, and the internal sealing performance of the flow control device can be improved by relatively reducing internal leakage of a working medium.

Description

technical field [0001] The invention relates to a flow control device in the field of heat exchange. Background technique [0002] Some thermal management systems in the background technology include a coolant circulation system, which is composed of heat converters, power electronics, drive motors, on-board chargers, water storage pots, high-temperature areas of electric water pump cooling water tanks, high-voltage PTCs, and air-conditioning radiators. Some reversing elements are used to switch the flow direction of the coolant through pipeline circulation; for example, hybrid vehicles usually add 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, the coolant reversing device is widely used in the hybrid and pure...
