Description

Technical Field

[0001] The utility model relates to the technical field of vehicle thermal management systems, and particularly relates to a five-way valve. Background Art

[0002] Automotive electronic water valves play a crucial role in automotive thermal management systems. Especially in electric vehicles and hybrid vehicles, they precisely control the flow of coolant to maintain suitable temperatures for the battery, motor, electronic devices, and passenger compartment. They are typically controlled by the vehicle's electronic control unit (ECU), which adjusts the coolant flow based on inputs from various sensors such as temperature sensors and load sensors. In currently available vehicle models, it is common to mix multiple three-way valves and four-way valves to meet different working requirements. However, with the increasing complexity and demand of the thermal management system, the space occupied by the combination of these three-way valves and four-way valves also increases. From the aspects of cost savings, weight reduction, and layout space, it becomes more important to integrate multiple three-way valves and multiple four-way valves into a smaller number of multi-way valves. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a five-way valve and a thermal management system to solve, to a certain extent, the technical problem of large space occupation by the combination of three-way valves and four-way valves in the prior art.

[0038] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third", "fourth", "fifth", "sixth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0040] In addition, the terms "horizontal", "vertical", "hanging", etc. do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0041] Such as Figures 1 to 11As shown in the figure, the utility model provides a five-way valve, which includes: a valve body 1, the valve body 1 includes a valve body bottom plate 101 and a valve body side plate 102 (the valve body bottom plate 101 and the valve body side plate 102 can be integrally formed; or, the valve body bottom plate 101 and the valve body side plate 102 are separately arranged and connected by means of threaded connection, snap connection, interference fit, welding or bonding, etc.), and an installation cavity is formed between the valve body bottom plate 101 and the valve body side plate 102; a first flow port 103 and a second flow port 104 are provided on the valve body bottom plate 101; a third flow port 105, a fourth flow port 106 and a fifth flow port 107 are provided on the valve body side plate 102; and in the projection of the valve body bottom plate 101, the second flow port 104 is located between the first flow port 103 and the valve body side plate 102; a valve core 2, rotatably arranged in the installation cavity; the valve core 2 includes a valve core bottom plate and a valve core side wall (the valve core bottom plate and the valve core side wall can be integrally formed; or, the valve core bottom plate and the valve core side wall are separately arranged and connected by means of threaded connection, snap connection, interference fit, welding or bonding, etc.), a first communication port 201 and a second communication port 202 are provided on the valve core bottom plate, and a third communication port 203, a fourth communication port 204 and a fifth communication port 205 are provided on the valve core side wall; the valve core 2 further includes a first flow channel 208 connecting the first communication port 201 and the third communication port 203, a second flow channel 209 connecting the first communication port 201 and the fourth communication port 204, and a third flow channel 210 connecting the second communication port 202 and the fifth communication port 205; the first flow port 103 is always communicated with the first communication port 201, and when the valve core rotates relative to the valve body, at least when the second flow port is communicated with the third flow port, the first flow port is communicated with the fourth flow port or the fifth flow port, and when the first flow port is communicated with the third flow port, the second flow port is communicated with the fourth flow port or the fifth flow port.

[0042] In this embodiment, the valve core 2 is installed in the installation cavity of the valve body 1. The valve core 2 can rotate in the installation cavity driven by the actuator 5. During the rotation of the valve core 2, the first flow port 103 and the first communication port 201 are always in communication. The relative rotation of the valve core with respect to the valve body can at least achieve: alternatively, when the second flow port 104 is in communication with the third flow port 105, the first flow port 103 is in communication with the fourth flow port 106, or the first flow port 103 is in communication with the fifth flow port. Specifically, when the second flow port 104, the second communication port 202, the third flow channel 210, the fifth communication port 205, and the third flow port 105 form a fluid channel, the first flow port 103, the first communication port 201, the first flow channel 208, the third communication port 203, and the fourth flow port 106 form a fluid channel or the first flow port 103, the first communication port 201, the first flow channel 208, the third communication port 203, and the fifth flow port 107 form a fluid channel; when the first flow port 103 is in communication with the third flow port 105, the second flow port 104 is in communication with the fourth flow port 106, or the second flow port 104 is in communication with the fifth flow port 107. Specifically, when the first flow port 103, the first communication port 201, the second flow channel 209, the fourth communication port 204, and the third flow port form a fluid channel, the second flow port 104, the second communication port 202, the third flow channel 210, the fifth communication port 205, and the fourth flow port 106 form a fluid channel or the second flow port 104, the second communication port 202, the third flow channel 210, the fifth communication port 205, and the fifth flow port 107 form a fluid channel. It can be seen from this that specifically, the five-way valve provided in this embodiment can at least simultaneously form two fluid channels. By rotating the valve core 2 and changing the communication ports corresponding to the flow ports, the path of the fluid channel can be changed.

[0043] The five-way valve provided in this embodiment integrates a three-way valve and a four-way valve into one, with a high integration degree and less occupied space. Combinations of multiple three-way valves and four-way valves in the thermal management system can be replaced by multiple five-way valves, thereby reducing the quantity of valves. On the one hand, it can reduce the installation space occupied by the valves and the quantity of pipelines. On the other hand, it reduces the installation of pipelines and valves, and reduces the flow resistance and leakage of the thermal management system. Additionally, the first flow port 103 and the second flow port 104 are arranged on the valve body bottom plate 101, the third flow port 105, the fourth flow port 106, and the fifth flow port 107 are arranged on the valve body side plate 102, and on the projection of the valve body bottom plate 101, the second flow port 104 is located between the first flow port 103 and the valve body side plate 102. That is, the third flow port 105, the fourth flow port 106, and the fifth flow port 107 are located on the same circumference to form a set of side flow port groups. Along the radial direction of the valve core 2, the first flow port 103, the second flow port 104, and the side flow port groups are arranged in sequence. Such an arrangement can reduce the rotation angle of the valve core 2, enable the five-way valve to reach the required working mode faster, and increase the distributable sealing angle to enhance the sealing performance of the five-way valve.

[0044] Among them, the first flow port 103 can be arranged at a non-central position on the valve body bottom plate 101, and the first communication port 201 is arranged at a non-central position on the valve core 2. In this way, the first flow port 103 and the first communication port 201 are arranged in an arc shape extending along the circumferential direction of the valve core 2, so as to ensure that there is always an overlapping part between the first flow port 103 and the first communication port 201, thereby realizing the continuous connection between the first flow port 103 and the first communication port 201.

[0045] As an alternative solution, as Figures 4 to 6 shown, the first flow port 103 is located at the center of the valve body bottom plate 101; the first communication port 201 is coaxially arranged with the first flow port 103.

[0046] In this embodiment, no matter which angle the valve core 2 rotates to, the first flow port 103 and the first communication port 201 are always facing each other. On the one hand, it makes the continuous connection between the first flow port 103 and the first communication port 201 more reliable. On the other hand, it is convenient for processing and reduces the occupied space.

[0047] More preferably, an annular protrusion can be arranged on the edge of the first communication port 201, and the annular protrusion can be inserted into the first flow port 103.

[0048] As an alternative solution, as Figure 4 、 Figures 7 to 10 shown, the third flow port 105, the fourth flow port 106, and the fifth flow port 107 are located on the same side of the valve body side plate 102; the fourth flow port 106 is located between the third flow port 105 and the fifth flow port 107.

[0049] The five-way valve provided in this embodiment can achieve multiple working modes. For example, when the second communication port 202 is in communication with the second flow port 104, by rotating the valve core 2, when the second communication port 202 is in communication with the second flow port 104, the third communication port 203 can be in communication with the fourth flow port 106, or the third communication port 203 can be in communication with the fifth flow port 107. When the second flow port 104 and the second communication port 202 are in communication, it can be achieved that, as Figure 7 shown, when the second flow port 104, the second communication port 202, the third flow path 210, the fifth communication port 205, and the third flow port 105 form a fluid channel, the first flow port 103, the first communication port 201, the first flow path 208, the third communication port 203, and the fourth flow port 106 form another fluid channel; or, as Figure 8 shown, when the second flow port 104, the second communication port 202, the third flow path 210, the fifth communication port 205, and the third flow port 105 form a fluid channel, the first flow port 103, the first communication port 201, the first flow path 208, the third communication port 203, and the fifth flow port 107 form another fluid channel.

[0050] By rotating the valve core 2, when the fifth communication port 205 is in communication with one of the fourth flow port 106 and the fifth flow port 107, one of the third communication port 203 and the fourth communication port 204 is in communication with the third flow port 105. When the second flow port 104 and the second communication port 202 are in communication, it can be achieved that, as Figure 9 shown, when the second flow port 104, the second communication port 202, the third flow path 210, the fifth communication port 205, and the fourth flow port 106 form a fluid channel, the first flow port 103, the first communication port 201, the second flow path 209, the fourth communication port 204, and the third flow port 105 form another fluid channel; or, as Figure 10 shown, when the second flow port 104, the second communication port 202, the third flow path 210, the fifth communication port 205, and the fifth flow port 107 form a fluid channel, the first flow port 103, the first communication port 201, the second flow path 209, the fourth communication port 204, and the third flow port 105 form another fluid channel.

[0051] When the second fluid passage port 104, the second communication port 202, the third flow channel 210, the fifth communication port 205, and the third fluid passage port 105 form a fluid channel, the first fluid passage port 103, the first communication port 201, the first flow channel 208, the third communication port 203, and the fifth fluid passage port 107 form another fluid channel. When the second fluid passage port 104, the second communication port 202, the third flow channel 210, the fifth communication port 205, and the third fluid passage port 105 form a fluid channel, the first fluid passage port 103, the first communication port 201, the first flow channel 208, the third communication port 203, and the fourth fluid passage port 106 form another fluid channel.

[0052] The first fluid passage port 103, the first communication port 201, the first flow channel 208, the third communication port 203, and the fourth fluid passage port 106 form another fluid channel.

[0053] Of course, more working modes can be realized, which will not be elaborated here.

[0054] Specifically, the circumferential angle of the third fluid passage port 105 is approximately the sum of the circumferential angles of the fourth fluid passage port 106 and the fifth fluid passage port 107 (it should be noted that "approximately" means that the circumferential angle of the third fluid passage port 105 being the sum of the circumferential angles of the fourth fluid passage port 106 and the fifth fluid passage port 107 is not absolute. Due to the existence of processing errors, within a certain error range, the circumferential angle of the third fluid passage port 105 is the sum of the circumferential angles of the fourth fluid passage port 106 and the fifth fluid passage port 107).

[0055] As an alternative, as Figure 4 、 Figures 7 to 10 shown, the side of the third fluid passage port 105 facing the valve core 2 is the inner port. A partition plate 108 is provided in the inner port. The partition plate 108 divides the inner port into a first shunt port 1051 and a second shunt port 1052. It can also be understood that the third fluid passage port 105 communicates with the installation cavity through the first shunt port 1051 and the second shunt port 1052. With such a setting, the partition plate 108 can support the internal leakage sealing ring 3, enabling the internal leakage sealing ring 3 to better seal the valve core 2.

[0056] Specifically, the second flow port 104 is arranged in an arc shape extending along the circumferential direction of the valve body bottom plate 101; the circumferential angle of the second flow port 104 is not less than the sum of the circumferential angles of the third flow port 105, the fourth flow port 106, and the fifth flow port 107. Optionally, the circumferential angle of the second flow port 104 is equal to the sum of the circumferential angles of the third flow port 105, the fourth flow port 106, and the fifth flow port 107. The circumferential angles of the fourth flow port 106 and the fifth flow port 107 are the same, the circumferential angle of the third flow port 105 is twice the circumferential angle of the fourth flow port 106, and the circumferential angle of the second flow port 104 is four times the circumferential angle of the fourth flow port 106.

[0057] Optionally, a valve body reinforcing rib 109 can be arranged in the second flow port 104, that is, the second flow port 104 is arranged in a hollow grid shape, thereby improving the strength of the valve body 1 and the stability of the second flow port 104.

[0058] As an alternative solution, as Figures 6 to 10 shown, in the projection of the valve core bottom plate, the valve core 2 includes three sector areas that roughly divide the valve core 2 into three equal parts (it should be noted that "roughly" means that the three sector areas are not absolutely trisected. Due to machining errors, within a certain error range, the three sector areas are trisected); the first flow channel 208, the second flow channel 209, and the third flow channel 210 are all located in the same sector area, and along the circumferential direction of the valve core 2, the third flow channel 210 is located between the first flow channel 208 and the second flow channel 209.

[0059] The valve core 2 provided in this embodiment can have a simple structure while being able to cooperate with the valve body 1 to achieve corresponding working modes.

[0060] As Figures 1 to 10 shown, on the basis of the above embodiment, further, a sixth communication port 206 is also provided on the valve core bottom plate, and a seventh communication port 207 is also provided on the valve core side wall; the valve core 2 further includes a fourth flow channel 211 that communicates the seventh communication port 207 and the sixth communication port.

[0061] In this embodiment, by rotating the valve core 2, more working modes can be achieved.

[0062] For example: the second flow port 104, the sixth communication port 206, the fourth flow channel 211, the seventh communication port 207, and the fifth flow port 107 form a fluid channel.

[0063] As an alternative solution, as Figure 6As shown, on the projection of the valve core bottom plate, the valve core 2 includes three fan-shaped areas that roughly trisect the valve core 2 (it should be noted that "roughly" means that the three fan-shaped areas are not absolutely trisected. Due to machining errors, within a certain error range, the three fan-shaped areas are trisected); the first flow channel 208, the second flow channel 209, and the third flow channel 210 occupy the same fan-shaped area; the fourth flow channel 211 occupies the other two fan-shaped areas.

[0064] Optionally, a valve core reinforcing rib 212 is provided in the fourth flow channel 211, so as to improve the strength of the valve core 2 and the stability of the fourth flow channel 211.

[0065] As Figure 2 shown, on the basis of the above-mentioned embodiment, further, an X-shaped ring seal is provided between the bottom of the valve core and the bottom of the valve body to prevent the first flow port and the second flow port from cross-flowing; an internal leakage seal ring is provided between the side of the valve core and the side of the valve body, so as to ensure the sealing performance of the entire five-way valve.

[0066] As Figure 11 shown, on the basis of the above-mentioned embodiment, further, and / or, the five-way valve further includes: an actuator 5, including: a motor 501, a worm 502, a first gear 503, a second gear 504, and a third gear 505; the motor 501 is drivingly connected to the worm 502, and the worm 502, the first gear 503, the second gear 504, and the third gear 505 are drivingly connected in sequence; the third gear 505 is drivingly connected to the valve core 2, and the transmission of the actuator 5 is reliable and the structure is compact.

[0067] As Figure 2 shown, the five-way valve further includes an end cover 6. After the valve core 2 is installed in the installation cavity, the end cover 6 is installed at the opening of the installation cavity.

[0068] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention. In the specification provided here, a large number of specific details are described. However, it can be understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures, and technologies have not been shown in detail so as not to obscure the understanding of this specification.
