Description

Technical Field

[0001] The utility model relates to the technical field of multi-way valves, and in particular to a multi-way valve used in a thermal management system of a new energy vehicle. Background Art

[0002] Traditional automotive thermal management systems often use three-way valves and four-way valves, and their sealing principle is: accurately control the matching size of the valve core and the valve housing, and rely on the small matching clearance between the valve core and the valve housing to reduce the leakage of non-connected pipelines. There are problems such as large torque of the valve core rotation and rapid wear of the valve core. Similarly, in the thermal management system and other systems of new energy vehicles, it is usually necessary to use a control valve with multiple passages (multi-way valves used in the thermal management system of new energy vehicles) to control the on-off of each circuit and the switching of the passages.

[0003] At the same time, the structure and functions of new energy vehicles are quite different from those of traditional fuel vehicles, especially the "heat-temperature" control system, which is more integrated and more complex to control. As an important functional component of the "heat-temperature" control system, the control valve is used to open / close various channels of the "heat-temperature" control system, which directly determines whether the various functions of the "heat-temperature" control system can be realized.

[0004] Among them, since the piping system of new energy vehicles is more complex than that of traditional vehicles, the use of traditional three-way valves and four-way valves requires a larger installation space, which also leads to an increase in the cost of the thermal management system. Therefore, in order to adapt to the increasingly complex control functions of the "heat-temperature" control system, various types of multi-way valves have been developed in recent years. However, the existing multi-way valves are limited by the traditional structural form, and their potential functions have not been fully utilized. There are few flow path connection modes that can be realized, which makes it difficult to meet the use requirements of the thermal management system of new energy vehicles. Utility Model Content

[0005] In view of the technical problem that the existing multi-way valves used in the thermal management system of new energy vehicles have few flow path connection modes and are difficult to meet the use requirements of the thermal management system of new energy vehicles; the utility model provides a multi-way valve for the thermal management system of new energy vehicles, with valve ports vertically arranged in parallel on one side of the valve body, and corresponding flow channels arranged on the valve body, so that the connection between each flow channel and the corresponding valve port can be achieved by rotating the valve core relative to the valve body. The multi-way valve has a variety of flow path connection modes to meet the use requirements of the thermal management system of new energy vehicles.

[0006] The utility model is realized by the following technical solutions:

[0007] The utility model provides a multi-way valve for a thermal management system of a new energy vehicle, comprising: a valve body, the two ends of the valve body are closed, a valve cavity is arranged inside the valve body, a side wall of the valve body is arranged with a plurality of valve ports in parallel along its own axial direction, and each of the valve ports is connected to the valve cavity; a valve core, the valve core is provided with a plurality of flow channels, and the valve core can rotate around its own axis; a sealing gasket, the sealing gasket is located between an inner wall of a side of the valve body where the valve ports are arranged and an outer wall of the valve core, the sealing gasket can seal the gap between the valve core and the valve body, and the sealing gasket is provided with a plurality of guide ports, each of the guide ports corresponds to each of the valve ports one by one; wherein, after the valve core is rotated by a preset angle, the flow channels on the valve core can connect the corresponding valve ports according to the corresponding flow path connection mode.

A valve core is arranged in a valve body with closed ends, and a plurality of flow channels are arranged on the valve core, and a plurality of valve ports are arranged on the side wall of the valve body. At the same time, a sealing gasket is arranged between an inner wall of one side of the valve body where the valve ports are arranged and an outer side wall of the valve core. A plurality of guide ports corresponding to the valve ports are arranged on the sealing gasket. When the valve core rotates a preset angle, the correspondence between the flow channel on the valve body and the valve port is switched to control the opening / closing of the corresponding valve port and / or adjust the connection between one valve port and another valve port.

[0009] Among them, the valve ports are axially arranged in parallel along the side wall of the valve body, and a sealing gasket is arranged between the inner wall of one side of the valve body where the valve ports are arranged and the outer wall of the valve core. On the one hand, it can prevent non-functional liquid cross-linking between the valve ports and ensure that the entire multi-way valve used in the thermal management system of new energy vehicles has good sealing performance. On the other hand, compared with the method of arranging the valve ports on the side wall and the end of the valve body, the cross-sectional size of the multi-way valve is small, which can reduce the volume of the multi-way valve used in the thermal management system of new energy vehicles and reduce its requirements for installation space.
