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

[0025] 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 through which the flow control device flows 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.

[0026] The flow control device 100 is installed in the pipeline of the air-conditioning system of the new energy vehicle, and can be used to switch between the heating flow path of the air-condi...

Abstract

The invention relates to a flow control device used for vehicle heat exchange systems. The flow control device comprises a shell, a valve element assembly and a control part; a transmission part comprises a pivot part and a second transmission part which are integrally formed, wherein the outer peripheral side of the pivot part is in pivot fit with the shell, the shell is correspondingly providedwith a pivot fit part in a protruding manner, the pivot fit part is provided with a pivot concave part for containing the pivot part, and the pivot concave part is communicated with a through hole; and the peripheral side of the pivot fit part is in contact with the outer peripheral side of the pivot part, a first valve block and a second valve block are in sealed arrangement, and the sealing performance of the product can be improved.

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 generally includes at least a heat converter, a drive motor, a water storage tank, an electric water pump, a flow switching element, a high temperature area of ​​a cooling water tank, and a high-pressure PTC. The flow switching element is connected through a pipeline cycle , can be used to switch the flow direction of the coolant; 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. During the process of switching the PTC heating device, Coolant flow needs to be switched. [0003] At present, coolant flow switching components are widely used in hybrid and pure electric vehicle industries, such as motor-driven piston val...
