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.

Embodiment Construction

[0019] see Figure 1 to Figure 5 As shown, the flow control device 100 can be applied to heat exchange systems, such as household air-conditioning systems or vehicle air-conditioning systems, etc. Specifically, the flow medium controlled by the flow control device can be water, a mixed liquid of other liquids and water Or other cooling liquids with thermal conductivity, the flow control device is arranged on the connecting pipeline of the vehicle air-conditioning system circuit or the coolant circuit, the flow control device controls the distribution of the flow medium and makes the flow medium and other working media of the heat exchange system Performing heat exchange, and then controlling the flow medium in the flow path of the heat exchange system by adjusting and distributing the outlet flow of the medium of the flow control device, can improve and optimize the control performance of the flow path of the heat exchange system.

Abstract

A flow control device used for a heat exchange system comprises a shell body, a transmission piece and a first valve piece. The first valve piece comprises a valve main body; a first contact part anda first communicating channel are formed in the valve main body; an opening of the first communicating channel penetrates through one side of the valve main body and faces the side where the first valve piece is located; the first contact part surrounds the radial circumferential side of the opening of the first communicating channel; and a second contact part is further formed on the flow controldevice and located on the radial circumferential side of a circulating valve opening, and the first contact part and the second contact part are arranged in a movable seal mode. The transmission piece can drive the first valve piece through a second transmission part to rotate stably, the movable sealing property of the movable valve piece and the matched part can be improved, inner leakage of aworking medium is relatively reduced, and the inner sealing property of the flow control device can be improved.

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...
