Description

Technical Field

[0001] This utility model relates to the field of directional valve technology, specifically to a four-way valve with a C42 combination. Background Technology

[0002] With the booming development of the new energy vehicle industry and the widespread application of electrochemical energy storage systems, battery thermal management technology has become a key factor in improving system performance and ensuring safety. In the pursuit of efficient and precise thermal management, higher requirements are placed on heat exchange between different components and the adjustment of heat exchange medium flow direction under different operating conditions.

[0003] Currently, most automotive thermal management systems use integrated modules or three-way solenoid valves to control the flow of cooling media. In some more complex thermal management systems, more complex four-way valves are involved, which often require two three-way valves for control. This results in a large space occupation, low integration, and is not conducive to system integration and space optimization. Utility Model Content

[0004] This invention provides a C42 combined four-way valve, which can solve the problem of large space occupation and low integration caused by the interconnection of any two channels of the four-channel valve in the prior art, which is mainly achieved by using two two-position three-way valves.

[0005] A four-way valve with a C42 assembly according to the present invention includes: a valve body and a valve core, wherein the valve body is provided with a switching chamber for installing the valve core; a first valve body pipe joint is provided axially at the end of the valve body, and a second valve body pipe joint and at least two third valve body pipe joints are provided radially at intervals on the side wall of the valve body, wherein the first valve body pipe joint, the second valve body pipe joint and the third valve body pipe joint are all connected to the switching chamber; a first valve core port is provided axially at the end of the valve core and is connected to the first valve body pipe joint, and a second valve core port and at least two third valve core ports are provided radially at intervals on the side wall of the valve core; when the second valve core port can be rotated to a position connected to the second valve body pipe joint or the third valve body pipe joint, the third valve body pipe joint and the third valve core port are interconnected.

[0006] The rotating design of the valve core in this invention allows for flexible switching of the connection state between different pipe joints. The four pipe joints can be freely and flexibly connected, meeting the needs for adjusting the flow direction of the heat exchange medium under various operating conditions, optimizing the efficiency of the thermal management system, and reducing energy loss.

[0007] In this utility model, a first channel penetrating the valve core is provided between the first valve core port and the second valve core port; a second channel penetrating the valve core is provided between each pair of third valve core ports.

[0008] The arrangement of the first and second channels in this invention allows the heat exchange medium to flow smoothly inside the valve core, reducing flow resistance and energy loss.

[0009] In this utility model, the first channel connects the first valve body pipe connector to the second valve body pipe connector or the third valve body pipe connector, and the second channel connects the second valve body pipe connector to the third valve body pipe connector or two third valve body pipe connectors.

[0010] The design of the first and second channels in this invention enables interconnection between any two channels of the four-way valve, meeting the needs of complex thermal management systems and allowing the four-way valve to flexibly adjust the flow direction of the heat exchange medium under various operating conditions.

[0011] In this utility model, the valve body is provided with a valve cover for sealing the conversion chamber at the end away from the first valve body pipe joint. The valve cover is provided with an installation port, and the installation port is provided with a sealing block for sealing the installation port. The sealing block is provided with a valve core shaft hole.

[0012] The valve cover and sealing block in this invention enhance the sealing performance of the four-way valve, preventing leakage of the heat exchange medium and preventing external impurities from corroding the inside of the four-way valve.

[0013] In this utility model, a first sealing groove is provided on both side walls of the valve body, and a first O-ring is provided in the first sealing groove. The inner diameter of the first O-ring is the same as the inner diameter of the first sealing groove.

[0014] By setting a first O-ring at the first sealing groove at both ends of the valve body in this utility model, double sealing is achieved, further improving the sealing performance of the four-way valve.

[0015] In this utility model, a second sealing groove is provided on the side wall of the sealing block, and a second O-ring with the same outer diameter as the installation port is provided at the edge of the second sealing groove and the end of the sealing block away from the valve core. A third sealing groove is provided inside the end of the valve core shaft hole away from the valve core, and a third O-ring with the same inner diameter as the inner diameter of the third sealing groove is provided at the third sealing groove.

[0016] The triple sealing achieved by the second and third O-rings in this invention further improves the sealing performance of the four-way valve, preventing external impurities from entering the valve through the installation port. The second O-ring at the sealing block also provides additional limiting effect on the valve core.

[0017] In this utility model, the valve body also includes a stepper motor disposed on the upper part of the valve cover away from the valve core. The stepper motor is fixedly connected to the valve cover, and the valve core is provided with a spline groove at the end away from the first valve body pipe joint to cooperate with the stepper motor to drive the valve core.

[0018] The stepper motor in this invention enables the electric control of the four-way valve. The motor shaft of the stepper motor passes through the valve core shaft hole and is fixedly connected to the spline groove on the valve core, driving the valve core to rotate, thereby achieving the connection of any two channels.

[0019] In this utility model, the four-way valve has a first O-ring seal at both ends of the valve body to prevent impurities from passing through the first valve body pipe joint and the installation port. The first O-ring seal on the side wall of the sealing block, the second O-ring seal on the top of the sealing block, and the third O-ring seal at the valve core shaft hole further improve the sealing effect. The motor shaft on the stepper motor passes through the valve core shaft hole and is fixed to the spline groove of the valve core. The stepper motor drives the valve core to rotate, changing the relative angle between the valve core and the valve body to realize the four pipe joints, which can be switched arbitrarily in pairs.

[0020] This invention features smooth internal flow channels, minimal impact of valves on pipeline flow resistance, simple valve structure, and lower cost and failure rate compared to using two three-way valves. Attached Figure Description

[0030] The rotating design of the valve core 200 in this embodiment allows for flexible switching of the connection state between different pipe joints. The four pipe joints can be freely and flexibly connected, meeting the needs for adjusting the flow direction of the heat exchange medium under various operating conditions, optimizing the efficiency of the thermal management system, and reducing energy loss.

[0031] In this embodiment, a first channel 240 penetrating the valve core 200 is provided between the first valve core port 210 and the second valve core port 220; a second channel 250 penetrating the valve core 200 is provided between each pair of third valve core ports 230.

[0032] The arrangement of the first channel 240 and the second channel 250 in this embodiment enables the heat exchange medium to flow smoothly inside the valve core 200, reducing flow resistance and energy loss.

[0033] In this embodiment, the first channel 240 connects the first valve body pipe connector 120 to the second valve body pipe connector 130 or the third valve body pipe connector, and the second channel 250 connects the second valve body pipe connector 130 to the third valve body pipe connector 140 or two third valve body pipe connectors 140.

[0034] Through the design of the first channel 240 and the second channel 250 in this embodiment, the interconnection between any two channels of the four-way valve is realized, which meets the needs of complex thermal management systems and enables the four-way valve to flexibly adjust the flow direction of the heat exchange medium under various operating conditions.

[0035] In this embodiment, the valve body 100 is provided with a valve cover 150 for sealing the conversion chamber 110 at one end away from the first valve body pipe joint 120. The valve cover 150 is provided with an installation port 151, and the installation port 151 is provided with a sealing block 160 for sealing the installation port 151. The sealing block 160 is provided with a valve core shaft hole 161.

[0036] The valve cover 150 and sealing block 160 in this embodiment enhance the sealing performance of the four-way valve, preventing leakage of the heat exchange medium and preventing external impurities from corroding the interior of the four-way valve.

[0037] In this embodiment, a first sealing groove 170 is provided at both ends of the valve body 100, and a first O-ring 171 is provided at the first sealing groove 170. The inner diameter of the first O-ring 171 is the same as the inner diameter of the first sealing groove 170.

[0038] By setting a first O-ring 171 at the first sealing groove 170 at both ends of the valve body 100 in this embodiment, double sealing is achieved, which further improves the sealing performance of the four-way valve. The first O-ring 171 at the sealing block 160 also provides a limiting effect on the valve core 200.

A second O-ring 172 with the same outer diameter as the mounting port 151 is provided at the edge of the second sealing groove 162 and the edge of the sealing block 160 away from the valve core 200. A third sealing groove 163 is provided inside the end of the shaft hole 161 of the valve core 200 away from the valve core 200. A third O-ring 173 with the same inner diameter as the third sealing groove 163 is provided at the third sealing groove 163.

[0040] The triple seal achieved by the second O-ring 172 and the third O-ring 173 in this embodiment further improves the sealing performance of the four-way valve and prevents external impurities from entering the interior of the four-way valve through the mounting port 151. The second O-ring 172 at the sealing block 160 also provides an additional limiting effect on the valve core 200.

[0041] In this embodiment, the valve body 100 also includes a stepper motor 300 disposed on the upper part of the valve cover 150 away from the valve core 200. The stepper motor 300 is fixedly connected to the valve cover 150. The valve core 200 is provided with a spline groove 260 at the end away from the first valve body pipe joint 120, which cooperates with the stepper motor 300 to drive the valve core 200.

[0042] In this embodiment, the stepper motor 300 enables the electric control of the four-way valve. The motor shaft on the stepper motor 300 passes through the valve core shaft hole 161 and is fixedly connected to the spline groove 260 on the valve core 200, driving the valve core 200 to rotate, thereby achieving the connection of any two channels.

[0043] In this embodiment, the four-way valve, when in use, utilizes the first O-ring seals 171 at both ends of the valve body 100 to prevent impurities from passing through the first valve body pipe joint 120 and the mounting port 151. The second O-ring seals 171 on the side wall of the sealing block 160, the second O-ring seals 172 on the inner top wall of the sealing block 160, and the third O-ring seals 173 in the valve core shaft hole 161 further enhance the sealing effect. The motor shaft on the stepper motor 180 passes through the valve core 200 shaft hole 161 and is fixed to the spline groove 260 of the valve core 200. The stepper motor 300 drives the valve core 200 to rotate, changing the relative angle between the valve core 200 and the valve body 100 to achieve the switching of the four pipe joints in any two pairs. This four-way valve in this embodiment enables multi-condition switching for the thermal management of energy storage products. Especially in energy storage using liquid-cooled PCS, combined with thermal management strategies, it can reduce overall thermal management energy consumption by two-thirds or more. At the same time, this four-way valve can be further integrated or expanded to make similar five-way valves, six-way valves, and eight-way valves to meet the needs of switching different pipelines.
