Description

Technical Field

[0001] This utility model relates to a valve, and more particularly to a five-way valve with proportional adjustment and a thermal management assembly. Background Technology

[0002] Currently, with the continuous development of new energy vehicles, the entire thermal management circuit of new energy vehicles is becoming increasingly complex, and the switching between various thermal management modes is becoming more frequent. To address the control problem of multiple circuits, it is mainly achieved through various multi-way valves with different functions. The switching between different thermal management modes is achieved by using the different structures and stopping angles of the multi-way valve cores.

[0003] Currently, the conventional solutions are three-way water valves and four-way water valves. Three-way water valves are used to realize the proportional regulation function of two circuits, while four-way water valves realize the series and parallel connection between two different circuits to realize the switching of different modes. Since there are more than two thermal management circuits, multiple three-way and four-way valves are often required to realize different modes of function. This leads to a gradual increase in the number of parts and costs, and a gradual increase in the complexity of part layout and control logic. Therefore, how to reduce the number of valves used while ensuring functionality has become an urgent problem to be solved. Summary of the Invention

[0017] In the above technical solution, when the valve core rotates to the first position, the first valve core flow channel connects the first valve housing flow channel port to the fifth valve housing flow channel port; the second valve core flow channel connects the second valve housing flow channel port to the third valve housing flow channel port; and the fourth valve housing flow channel port is closed by the valve core.

[0028] This utility model also provides a thermal management assembly, including the aforementioned five-way valve with proportional adjustment.

[0029] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0030] 1. In this utility model, two independent valve core flow channels are provided on the valve core, and five valve shell flow channel ports are provided on the inner wall of the valve shell receiving cavity. By rotating the valve core, at least two valve shell flow channel ports can be connected through different valve core flow channels. Furthermore, different rotation angles can adjust the connection angle with the corresponding valve shell flow channel ports, thereby adjusting the flow rate of the valve shell flow channel ports. This enables the functions of reversing and proportional regulation, effectively reducing the number of valves in the thermal management assembly, reducing the control difficulty and control cost, and also reducing the cost of the thermal management assembly.

[0031] 2. In this utility model, one end of the valve shell flow channel is connected to the inner wall of the receiving cavity, and the other end is located at the bottom of the valve shell. No flow channel opening is provided on the outer periphery of the valve shell, which can make full use of the area at the bottom of the valve shell and does not occupy the circumferential space of the five-way valve. Under the same flow requirements, the entire five-way valve structure can be smaller and more compact, which is convenient for integrated installation.

[0032] 3. In this utility model, mutually cooperating limiting blocks are respectively set on the bracket and the valve core, which can limit the rotation angle of the valve core, prevent the valve core from rotating excessively, and facilitate the positioning of the actuator.

[0047] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0048] Example 1: See Figure 1-11 As shown, a five-way valve with proportional adjustment includes:

[0049] Valve housing 1, wherein a receiving cavity 11 is provided in the middle of the valve housing 1, and five valve housing flow passages 12 are provided on the inner wall of the receiving cavity 11;

[0050] The valve core 2 has two independent valve core flow channels 21 inside, and the two ends of each valve core flow channel 21 are respectively connected to the outer surface of the valve core 2; the valve core 2 is rotatably installed in the receiving cavity 11, and the outer surface of the valve core 2 is in sealed contact with the inner surface of the receiving cavity 11; each valve core flow channel 21 is respectively connected to at least two valve shell flow channel ports 12.

[0051] In this embodiment, two of the five valve shell flow channels are medium inlets, and the other three are medium outlets. Each valve core flow channel connects one medium inlet and at least one medium outlet. Specifically, one end of two valve core flow channels is connected to each of the two medium inlets, and the other end of each is connected to at least one medium outlet. Alternatively, one valve core flow channel may be connected to one medium outlet, and the other end of another may be connected to both medium outlets. By rotating the valve core, the position of the valve core flow channels is adjusted, thereby adjusting the connection between the medium inlets and different medium outlets, enabling the switching of different circuits and thus switching between different modes of the heat pipe circuit. Furthermore, the connection area between the valve core flow channels and the medium outlets can be adjusted according to the rotation angle of the valve core, thereby adjusting the flow rate between different circuits and achieving proportional regulation.

[0052] See Figure 1 , 2As shown, an actuator 3 is also provided above the valve housing 1 to drive the valve core 2 to rotate. The actuator controls the rotation angle of the valve core, thereby realizing the connection between the valve core flow channel and the valve housing flow channel opening to be connected, the connection area, the connection of the required circuit, and the flow regulation.

[0053] See Figure 2-4 As shown, a bracket 4 is also provided between the actuator 3 and the valve core 2, and the actuator 3 is mounted on the valve body 1 via the bracket 4;

[0054] A bracket limiting block 41 is provided on the bottom surface beside the axis of the bracket 4, and a valve core limiting block 22 is provided on the top of the valve core 2 beside the axis of the valve core 2, which cooperates with the bracket limiting block 41. The valve core limiting block 22 and the bracket limiting block 41 restrict the rotation angle of the valve core 2.

[0055] In this embodiment, the bracket is used to mount the actuator on the valve housing, ensuring a certain distance between the actuator and the valve housing, and facilitating the connection between the actuator and the valve core. In this embodiment, a rotating shaft 23 is located at the center of the valve core 2. The bottom of the shaft is below the bottom surface of the valve core, and the top of the shaft is above the top of the valve core. A positioning hole 13 is provided in the center of the bottom surface of the receiving cavity. The bottom of the rotating shaft is inserted into this positioning hole, achieving the installation and positioning of the valve core in the receiving cavity, and ensuring the smooth rotation of the valve core. When the valve core rotates, it rotates around the axis of the receiving cavity. The top of the rotating shaft passes through the bracket and connects to the actuator. Simultaneously, to facilitate the connection between the actuator and the rotating shaft, multiple protruding teeth are arranged around the top outer surface of the rotating shaft, forming a gear structure. The actuator connects to this gear structure, enabling the actuator to stably drive the rotating shaft and the valve core to rotate without slippage. The bracket limiting block and the valve core limiting block are designed so that, when the valve core is in its initial position, one side of the valve core limiting block contacts one side of the bracket limiting block, which can restrict the valve core from rotating in one direction (for example, if the bracket limiting block is on the clockwise side of the valve core limiting block, then the valve core cannot rotate in the clockwise direction). When the actuator drives the valve core to rotate in the other direction (counterclockwise), after rotating to a certain angle, the other side of the valve core limiting block contacts the other side of the bracket limiting block, which will restrict the valve core from rotating. Therefore, the valve core limiting block and the bracket limiting block can prevent the valve core from rotating excessively, which facilitates the actuator to position the valve core rotation.

[0056] Furthermore, in order to achieve a sealed contact between the outer surface of the valve core and the inner surface of the receiving cavity, so that the medium flowing out of the valve shell flow channel can only flow into the valve core flow channel and be sent to other valve shell flow channels through the valve core flow channel, an internal seal 5 is provided between the outer surface of the valve core 2 and the inner surface of the receiving cavity 11. The internal seal is preferably made of an elastic deformable material, such as rubber or silicone. The internal seal is an annular structure with a through hole in the middle of the annular structure that penetrates the top and bottom surfaces of the internal seal. The outer wall of the annular structure has 5 holes that communicate with the through hole. The outer surface of the internal seal abuts against the inner wall of the receiving cavity, and each hole is directly opposite a valve shell flow channel. The valve core is rotatably disposed in the through hole, and the outer surface of the valve core contacts the inner surface of the through hole on the internal seal. If the end of the valve core flow channel is between adjacent holes, the end of the valve core flow channel at that point is blocked. If the end of the valve core flow channel is connected to a hole, the end of the valve core flow channel at that point is connected. Depending on the valve core rotation angle, the valve core flow channel can connect different valve body flow channels.

[0057] In this embodiment, the valve housing 1 is provided with five valve housing flow channels. One end of the valve housing flow channel is connected to the receiving cavity 11 and forms the valve housing flow channel opening 12. The other end of the valve housing flow channel is connected to the bottom of the valve housing 1.

[0058] One end of the valve body flow channel is connected to the receiving cavity, and the other end is connected to the bottom of the valve body. The bottom of each valve body flow channel is connected to the pipeline on the thermal management assembly. In this way, the circumferential space of the five-way valve is not occupied, and all of it is concentrated at the bottom of the five-way valve. Under the same flow requirements, the structure of the five-way valve can be smaller and more compact, which is convenient for integrated installation.

[0059] Since the bottom of the valve body flow channel is connected to the bottom of the valve body, a bottom sealing gasket 6 is provided at the bottom of the valve body 1. The sealing gasket is made of flexible sealing materials such as rubber and silicone. The sealing gasket also has 5 holes, each of which is set at the bottom of a valve body flow channel. When the five-way valve is installed on the thermal management assembly, the bottom sealing gasket plays a sealing role.

[0060] See Figure 5-11 As shown, the five valve housing flow channels 12 are sequentially arranged along the first direction as the first valve housing flow channel 121, the second valve housing flow channel 122, the third valve housing flow channel 123, the fourth valve housing flow channel 124, and the fifth valve housing flow channel 125.

[0061] The valve core flow channel 21 includes a first valve core flow channel 211 and a second valve core flow channel 212.

[0062] In this embodiment, the first direction is counterclockwise, and the second direction is opposite to the first direction, being clockwise. The first and third valve body flow channels are medium inlets, and the second, fourth, and fifth valve body flow channels are medium outlets.

[0063] In this invention, the five-way valve has six operating modes: the valve core can rotate within the valve housing to a first position, a second position, a third position, a fourth position, a fifth position, and a sixth position, respectively. Each position corresponds to a different operating mode.

[0064] First mode: See Figure 6 As shown, when the valve core 2 rotates to the first position, the first valve core flow channel 211 connects the first valve housing flow channel port 121 with the fifth valve housing flow channel port 125; the second valve core flow channel 212 connects the second valve housing flow channel port 122 with the third valve housing flow channel port 123, and the fourth valve housing flow channel port 124 is closed by the valve core 2.

[0065] The first position can be used as the initial position. The two ends of the valve core flow channel are the inlet and outlet, respectively. The valve core flow channel has an arc-shaped structure, with the protrusions facing the valve core's axis. Two arc-shaped valve core flow channels are symmetrically arranged within the valve core. Therefore, when the valve core is in the first position, the first valve core flow channel connects the first valve housing flow channel opening with the fifth valve housing flow channel opening; the second valve core flow channel connects the second valve housing flow channel opening with the third valve housing flow channel opening. At this time, the outer wall of the valve core between the two valve core flow channels faces the fourth valve housing flow channel opening, blocking and closing it. The medium delivered from the first valve housing flow channel opening will be entirely delivered from the first valve core flow channel into the fifth valve housing flow channel opening, and the medium delivered from the third valve housing flow channel opening will be entirely delivered from the second valve core flow channel into the second valve housing flow channel opening, achieving a four-way function. The medium is a fluid, such as a liquid, gas, or other fluid medium.

[0066] The second mode: See Figure 7 As shown, when the valve core 2 rotates to the second position, the first valve core flow channel 211 connects the first valve housing flow channel port 121 with the fourth valve housing flow channel port 124 and the fifth valve housing flow channel port 125, and the second valve core flow channel 212 connects the second valve housing flow channel port 122 with the third valve housing flow channel port 123. Specifically, when the valve core 2 rotates from the first position along the first direction from 0° to 30° (excluding 0° and 30°), the valve core 2 is in the second position.

[0067] In this embodiment, the width of the end where the valve core flow channel communicates with the outer surface of the valve core is greater than the size of the valve shell flow channel opening. When the valve core is in the first position, it will exactly block and close the fourth valve shell flow channel opening, and the edge of the fifth valve shell flow channel opening will be directly opposite the edge of the end of the first valve core flow channel. However, when it rotates a certain angle along the first direction (counterclockwise direction), a portion of one end of the first valve core flow channel will be directly opposite the fourth valve shell flow channel opening, while the fifth valve shell flow channel opening will be partially blocked. At this time, the first valve shell flow channel opening will communicate with the fourth and fifth valve shell flow channel openings through the first valve core flow channel. Since the flow rate of the medium flowing out of the first valve shell flow channel opening is fixed, the smaller the counterclockwise rotation angle of the valve core, the larger the flow rate of the fourth valve shell flow channel opening. The area connected to the first valve core flow channel is smaller than the area connected to the fifth valve shell flow channel and the first valve core flow channel. This means the fluid flow rate from the first valve shell flow channel to the fourth valve shell flow channel is less than the fluid flow rate into the fifth valve shell flow channel. The larger the rotation angle towards the first direction, the greater the fluid flow rate from the first valve shell flow channel to the fourth valve shell flow channel and the smaller the flow rate into the fifth valve shell flow channel. Based on the rotation angle of the valve core towards the first direction, the flow rates from the first valve shell flow channel to the fourth and fifth valve shell flow channels are adjusted to achieve proportional regulation. Furthermore, at this time, the second valve shell flow channel is completely connected to the third valve shell flow channel through the second valve core flow channel, thus achieving four-way reversal and three-way functionality. Of course, if the valve core rotates towards the second direction (the second direction is opposite to the first direction; in this embodiment, the first direction is counterclockwise and the second direction is clockwise), it can rotate from the second position to the first position, reversing the flow rate ratio of fluid flowing into different valve shell flow channels.

[0068] The third mode: See Figure 8 As shown, when the valve core 2 is rotated to the third position, the first valve core flow channel 211 connects the first valve housing flow channel port 121 with the fourth valve housing flow channel port 124, the second valve core flow channel 212 connects the second valve housing flow channel port 122 with the third valve housing flow channel port 123, and the fifth valve housing flow channel port 125 is closed by the valve core 2.

[0069] When the valve core 2 rotates 30° from the first position along the first direction, the valve core 2 is in the third position;

[0070] Of course, the valve core can also rotate directly from the second position to the third position along the first direction, or from other positions along the first or second direction to the third position. However, when the valve core rotates from the first position to the third position, the rotation angle of the valve core is exactly 30°.

[0071] In this state, the outer surface of the valve core between the inlet and outlet of the first valve core flow channel precisely blocks and closes the fifth valve housing flow channel opening, allowing the medium flowing out of the first valve housing flow channel opening to flow entirely into the fourth valve housing flow channel opening through the first valve core flow channel. At this time, the medium flowing out of the third valve housing flow channel opening completely flows into the second valve housing flow channel opening through the second valve core flow channel. Compared with the first mode, this achieves the function of four-way reversing.

[0072] Fourth mode: See Figure 9 As shown, when the valve core 2 is rotated to the fourth position, the first valve core flow channel 211 connects the third valve housing flow channel port 123 with the fifth valve housing flow channel port 125; the second valve core flow channel 212 connects the first valve housing flow channel port 121 with the second valve housing flow channel port 122, and the fourth valve housing flow channel port 124 is closed by the valve core 2.

[0073] When the valve core 2 rotates 90° from the first position along the first direction, the valve core 2 is in the fourth position;

[0074] Of course, the valve core can also be rotated directly from the second or third position along the first direction to the fourth position, or from other positions along the second direction to the fourth position.

[0075] At this time, the outer surface of the valve core between the inlet and outlet at both ends of the first valve core flow channel exactly blocks and closes the fourth valve housing flow channel. The medium flowing out of the third valve housing flow channel will enter the first valve core flow channel and then flow out from the fifth valve housing flow channel. The medium flowing out of the first valve housing flow channel will flow into the second valve core flow channel and then flow out from the second valve housing flow channel, thus realizing four-way reversal.

[0076] Fifth mode: See Figure 10 As shown, when the valve core 2 is rotated to the fifth position, the first valve core flow channel 211 connects the third valve housing flow channel port 123 with the fourth valve housing flow channel port 124 and the fifth valve housing flow channel port 125; the second valve core flow channel 212 connects the first valve housing flow channel port 121 with the second valve housing flow channel port 122.

[0077] When the valve core rotates 90° to 120° (excluding 90° and 120°) from the first position along the first direction, the valve core is in the fifth position.

[0078] Of course, the valve core can also be rotated directly from the second, third, or fourth position along the first direction to the fifth position, or from other positions along the second direction to the fifth position.

[0079] When the valve core rotates exactly 90° from the first position along the first direction, the fourth valve body flow channel is completely blocked and closed. However, when it rotates a little further along the first direction, the fourth valve body flow channel and the end of the first valve core flow channel are connected slightly, and the fifth valve body flow channel is blocked slightly. Since the flow rate of the medium flowing from the third valve body flow channel into the first valve core flow channel is fixed, some medium will flow into the fourth valve body flow channel, while most will flow into the fifth valve body flow channel. If the rotation angle is larger (closer to 120 degrees), the fifth valve body flow channel is blocked more, and the fourth valve body flow channel is opened more. Therefore, the flow rate flowing into the fourth valve body flow channel will be greater than the flow rate flowing into the fifth valve body flow channel. By adjusting the rotation angle of the valve core according to the required flow rate, the connection area between the first valve core flow channel and the fourth and fifth valve body flow channels can be adjusted, thereby adjusting the flow rate flowing from the third valve body flow channel into the fourth and fifth valve body flow channels, achieving three-way flow regulation. Furthermore, at this time, the second valve core flow channel will completely connect the first valve body flow channel port and the second valve body flow channel port, without affecting the flow rate from the first valve body flow channel port to the second valve body flow channel port.

[0080] Sixth mode: See Figure 11 As shown, when the valve core 2 is rotated to the sixth position, the first valve core flow channel 211 connects the third valve housing flow channel port 123 with the fourth valve housing flow channel port 124; the second valve core flow channel 212 connects the first valve housing flow channel port 121 with the second valve housing flow channel port 122, and the fifth valve housing flow channel port 125 is closed by the valve core 2.

[0081] When the valve core rotates 120° from the first position along the first direction, the valve core is in the sixth position.

[0082] The valve core can be rotated directly from the first position, second position, third position, fourth position or fifth position along the first direction to the sixth position.

[0083] At exactly 120°, the outer surface of the valve core between the first valve core flow channel and the second valve core flow channel closes the fifth valve housing flow channel. The medium flowing out of the third valve housing flow channel flows into the fourth valve housing flow channel through the first valve core flow channel, and the medium flowing out of the first valve housing flow channel flows into the second valve housing flow channel through the second valve core flow channel, thus realizing four-way reversal.

[0084] Regardless of whether the valve core rotates to the second, third, fourth, fifth, or sixth position, when it rotates along the second direction (opposite to the first direction), it can rotate to other positions, thus switching modes. For example, when the sixth position rotates along the second direction, it can rotate to the fifth, fourth, third, second, and first positions. When the fifth position rotates along the second direction, it can rotate to the fourth, third, second, and first positions; when the fifth position rotates along the first direction, it can rotate to the sixth position. When the fourth position rotates along the second direction, it can rotate to the third, second, and first positions; when the fourth position rotates along the first direction, it can rotate to the fifth and sixth positions. When the third position rotates along the second direction, it can rotate to the second and first positions; when the third position rotates along the first direction, it can rotate to the fourth, fifth, and sixth positions. When the second position rotates along the second direction, it can rotate to the first position; when the second position rotates along the first direction, it can rotate to the third, fourth, fifth, and sixth positions.

[0085] Of course, the rotation of the valve core from the first position to the corresponding position by different angles is set according to the distance and angle relationship between the five valve body flow channels. If the distance and angle between the five valve body flow channels are different, the angle of rotation of the valve core is also adjusted synchronously to ensure that it rotates accurately to the corresponding position.

[0086] Due to the presence of the bracket limiting block and the valve core limiting block, when the valve core is in the first position, it can only rotate in the first direction. When the valve core is in the sixth position, it can only rotate in the second direction.

[0087] In this invention, the five-way valve with a multi-mode structure can replace the functions of a three-way proportional regulating valve and a four-way mode regulating valve, effectively improving the integration level of the thermal management assembly system and reducing control difficulty and cost.

[0088] This utility model also provides a thermal management assembly, including the aforementioned five-way valve with proportional adjustment.
