It is widely used in various industries.

[0003] In the related art, heat exchange plates are usually made with separation ribs to realize flow channels for different heat exchange media to flow through during the flow process. However, the separation ribs can easily lead to poor product reliability of the plate heat exchanger. Utility Model Content

[0006] In a first aspect, an embodiment of the present application provides a plate heat exchanger comprising a plurality of first circulation plates and a plurality of second circulation plates alternately arranged along a first direction, the first circulation plate comprising a first rib and a first plane portion, the first rib protruding from the first plane portion along the first direction, the second circulation plate comprising a second rib and a second plane portion, the second rib protruding from the second plane portion along the first direction; the plurality of first circulation plates and the second circulation plates alternately arranged jointly define the refrigerant flow channel and the coolant flow channel, the first rib is located in the refrigerant flow channel, and the second rib is located in the coolant flow channel; wherein, the second rib abuts against a side of the first plane portion facing away from the first rib, and the first rib abuts against a side of the second plane portion facing away from the second rib.

[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0036] The plate heat exchanger, thermal management system, and vehicle provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0037] See also Figures 1 to 7, an embodiment of the present application provides a plate heat exchanger, comprising a plurality of first circulation plates 10 and a plurality of second circulation plates 20 alternately arranged along a first direction, the first circulation plate 10 comprising a first rib 11 and a first plane portion 122, the first rib 11 protruding from the first plane portion 122 along the first direction, the second circulation plate 20 comprising a second rib 21 and a second plane portion 222, the second rib 21 protruding from the second plane portion 222 along the first direction; the plurality of first circulation plates 10 and the plurality of second circulation plates 20 alternately arranged jointly define a refrigerant flow channel and a coolant flow channel, the first rib 11 is located in the refrigerant flow channel, and the second rib 21 is located in the coolant flow channel; wherein the second rib 21 abuts against a side of the first plane portion 122 facing away from the first rib 11, and the first rib 11 abuts against a side of the second plane portion 222 facing away from the second rib 21.

[0038] It should be noted that the plate heat exchanger may include a first circulation plate 10, a second circulation plate 20, a refrigerant connector, a coolant connector, a mounting bracket, a top plate, a bottom plate and a cover plate component. The plate heat exchanger is used to achieve the function of heat exchange.

[0039] In the embodiment of the present application, the refrigerant flows into the refrigerant flow channel through the refrigerant joint, and the coolant flows into the coolant flow channel through the coolant joint. The coolant flow channel and the refrigerant flow channel are independent of each other to achieve heat exchange. Specifically, a plurality of first circulation plates 10 and a plurality of second circulation plates 20 arranged alternately with each other jointly define the refrigerant flow channel and the coolant flow channel. It can be understood that the refrigerant flow channel is used to provide a flow space for the refrigerant, and the coolant flow channel is used to provide a flow space for the coolant. The different temperatures of the media in the two flow channels achieve heat exchange. Among them, the first rib 11 is arranged in the refrigerant flow channel, and the second rib 21 is arranged in the coolant flow channel. The arrangement of the first rib 11 and the second rib 21 is used to increase the support strength of the first circulation plate 10 and the second circulation plate 20 respectively, to avoid fatigue aging of the first circulation plate 10 and the second circulation plate 20 during use, and to improve the reliability and stability of the first circulation plate 10 and the second circulation plate 20, thereby making the use of the heat exchanger safer and more reliable. Furthermore, the first ribs 11 and the second ribs 21 both protrude in the first direction. On the same circulation plate, the arrangement of the ribs protruding in the same direction can reduce the thinning rate of the first circulation plate 10 and the second circulation plate 20, reducing fatigue strength at the ribs, thereby increasing the strength of the first circulation plate 10 and the second circulation plate 20, thereby increasing the support strength of the circulation plate. Furthermore, it also facilitates processing. When the first circulation plates 10 and the second circulation plates 20 are arranged alternately, the first ribs 11 and the second ribs 21 protruding in the same direction can effectively increase the support strength of the overall structure and facilitate assembly. In addition, since the first rib 11 abuts against the side of the second flat portion 222 facing away from the second rib 21, and the second rib 21 abuts against the side of the first flat portion 122 facing away from the first rib 11, the first rib 11 and the second rib 21 can be staggered, which has the beneficial effect of further improving the structural strength of the staggered first circulation plate 10 and the second circulation plate 20. In addition, the abutment of the first rib 11 and the second flat portion 222, and the abutment of the second rib 21 and the first flat portion 122 can also improve the abutment stability, thereby improving the overall structural strength of the plate heat exchanger. Moreover, since the first rib 11 and the second rib 21 protrude in the same direction, and the first rib 11 abuts against the second flat portion 222, and the second rib 21 abuts against the first flat portion 122, the accumulation of ribs in the stamping height can be avoided, which in turn leads to an excessively large material thinning rate, thereby further improving the structural strength and reliability of the first circulation plate 10 and the second circulation plate 20.

[0040] Optionally, in the embodiment of the present application, the number of the first ribs 11 and the number of the second ribs 21 are not equal.

[0041] It should be noted that the smaller the height of the flow channel, the higher the reliability of the product, while the larger the height of the flow channel, the lower the flow resistance. In actual applications, the flow pressure of the refrigerant is generally greater than the flow pressure of the coolant. Therefore, the height of the refrigerant flow channel used to provide flow space for the refrigerant is generally less than the height of the coolant flow channel. If the number of the first rib 11 and the second rib 21 is not equal, the flow space of the refrigerant and coolant flow channels can be further adjusted by designing the number of the first rib 11 and the second rib 21, thereby further improving the reliability of the product.

[0042] It should also be noted that the refrigerant may be R134a (tetrafluoroethane), R410a (near-azeotropic mixture), R744 (carbon dioxide), etc., and this embodiment does not impose any limitation on this.

[0043] Optionally, in an embodiment of the present application, in the refrigerant flow channel, the distance between the first planar portion 122 and the second planar portion 222 is A, and in the coolant flow channel, the distance between the first planar portion 122 and the second planar portion 222 is B. When A>B, the number of first ribs 11 is less than the number of second ribs 21, and when A≤B, the number of first ribs 11 is greater than the number of second ribs 21.

[0044] Specifically, when the distance between the first planar portion 122 and the second planar portion 222 in the refrigerant flow channel is greater than the distance between the first planar portion 122 and the second planar portion 222 in the coolant flow channel, the number of first ribs 11 is less than the number of second ribs 21. For example, one first rib 11 is provided and two second ribs 21 are provided. When the distance between the first planar portion 122 and the second planar portion 222 in the refrigerant flow channel is less than or equal to the distance between the first planar portion 122 and the second planar portion 222 in the coolant flow channel, the number of first ribs 11 is greater than the number of second ribs 21. For example, two first ribs 11 are provided and one second rib 21 is provided. In the embodiment of the present application, by setting the number of the first rib 11 and the second rib 21 to vary with the height difference between the refrigerant flow channel and the coolant flow channel, the reliability of the first circulation plate 10 and the second circulation plate 20 can be effectively improved, and the first circulation plate 10 or the second circulation plate 20 can be prevented from failing due to excessive flow pressure of the medium, thereby having the beneficial effect of improving the reliability of the heat exchanger.

[0045] It should also be noted that, to improve the heat exchange efficiency of the plate heat exchanger, the plate heat exchanger may include multiple sets of first circulation plates 10 and second circulation plates 20 that are sealed from each other. This embodiment does not impose any restrictions on the specific number, and actual conditions may apply. Optionally, in this embodiment of the present application, the first circulation plate 10 further includes a first body 14, and the second circulation plate 20 further includes a second body 24. The first body 14 has a first planar portion 122, and the second body 24 has a second planar portion 222. In other words, the first rib 11 protrudes from the first body 14 along the first direction, and the second rib 21 protrudes from the second body 24 along the first direction.

[0046] In the embodiment of the present application, the first rib 11 protrudes from the first body 14 along a first direction, and the second rib 21 protrudes from the second body 24 along the first direction. It is understood that the first rib 11 and the second rib 21 protrude in the same direction. Furthermore, because the first rib 11 and the second rib 21 protrude in the same direction, in actual production, the first rib 11 and the second rib 21 are stamped in a single direction, thereby reducing the stamping difficulty. Simultaneously, the material thinning rate of the first circulation plate 10 and the second circulation plate 20 is also reduced, thereby having the beneficial effect of improving the product reliability of the first circulation plate 10 and the second circulation plate 20.

[0047] Optionally, in an embodiment of the present application, the first rib 11 extends along the length direction of the plate heat exchanger, and the first rib 11 is a strip structure; and / or the second rib 21 extends along the length direction of the plate heat exchanger, and the second rib 21 is a strip structure.

[0048] In the embodiment of the present application, the first rib 11 extends along the length of the plate heat exchanger, and the second rib 21 also extends along the length of the plate heat exchanger. It is understood that the first rib 11 and the second rib 21 extend in the same direction and are both strip-shaped in that direction. In actual production, the strip-shaped first and second ribs 11, 21 have a regular structure, which facilitates processing and facilitates coordination with other components.

[0049] Optionally, in an embodiment of the present application, the first planar portion 122 includes a first surface 12 and a second surface 13 arranged opposite to each other, the second planar portion 222 includes a third surface 22 and a fourth surface 23 arranged opposite to each other, the first rib 11 and the second rib 21 are staggered along the width direction of the plate heat exchanger, and the first rib 11 abuts against the fourth surface 23 of the second planar portion 222, and the second rib 21 abuts against the second surface 13.

[0050] In the embodiments of the present application, the staggered arrangement of the first and second ribs 11, 21 refers to the staggered arrangement of the first and second ribs 11, 21 across the width of the plate heat exchanger. It is understood that, for both the first and second circulation plates 10, 20, the material at the locations where the first and second ribs 11, 21 are stamped is necessarily thinner than at other locations. Failure of the first and second circulation plates 10, 20 is particularly prone to occur at locations where the material is thinner. In the prior art, if the locations where the material of the first and second circulation plates 10, 20 is thinner are not staggered, the ribs will accumulate in height, further weakening the structural strength of the plate-type sensor. Therefore, in the embodiments of the present application, staggering the first and second ribs 11, 21 has the beneficial effect of preventing failure of one of the first and second circulation plates 10, 20 from causing a cascading failure of the other. Furthermore, the first rib 11 abuts the fourth surface 23, where the fourth surface 23 is the portion of the second body 24 not connected to the second rib 21. As can be appreciated, the material of the first body 14 at the location of the fourth surface 23 is not thinned by the stamping of the second rib 21. Therefore, the abutment of the first rib 11 against the fourth surface 23 also has the beneficial effect of increasing the strength of the first rib 11 through the connection, thereby improving the reliability of the first circulation plate 10. The second rib 21 abuts the second surface 13, where the second surface 13 is the portion of the second body 24 not processed with the second rib 21. As can be appreciated, the material of the second body 24 at the location of the second surface 13 is not thinned by the stamping of the second rib 21. Therefore, the abutment of the second rib 21 against the second surface 13 also has the beneficial effect of increasing the strength of the second rib 21 through the connection, thereby improving the reliability of the second circulation plate 20. Furthermore, the above arrangement also has the beneficial effect of avoiding the accumulation of the stamping heights of the first rib 11 and the second rib 21, thereby avoiding excessive stamping, which leads to excessive material thinning rate and affects the material strength.

[0051] Optionally, in an embodiment of the present application, the first circulation plate 10 further includes a plurality of first spoiler protrusions 15, which are arranged on the first planar portion 122, and the first spoiler protrusions 15 protrude from the first planar portion 122 in a direction close to the refrigerant flow channel; and / or, the second circulation plate 20 further includes a plurality of second spoiler protrusions, which are arranged on the second planar portion 222, and protrude from the second planar portion 222 along the first direction.

[0052] In the embodiment of the present application, the first flow-disrupting protrusion 15 is provided to disrupt the flow of the refrigerant in the refrigerant flow channel. In actual use, the refrigerant flows in the refrigerant flow channel, and the first flow-disrupting protrusion 15 is provided on the first planar portion 122. The refrigerant is disrupted by the first flow-disrupting protrusion 15 during its flow in the flow channel. Specifically, the first flow-disrupting protrusion 15 protrudes from the first planar portion 122. Furthermore, the first flow-disrupting protrusion 15 can also abut against the fourth surface 23, which has the beneficial effect of further improving the reliability of the first circulation plate 10.

[0053] Furthermore, the second circulation plate 20 may also be provided with a plurality of second flow-disrupting protrusions, which are provided to disrupt the flow of the coolant in the coolant flow channel. In actual use, the coolant flows in the coolant flow channel, and the second flow-disrupting protrusions are provided on the second planar portion 222. The coolant is disrupted by the second flow-disrupting protrusions during its flow in the flow channel. Specifically, the second flow-disrupting protrusions protrude from the second planar portion 222, which has the beneficial effect of further improving the reliability of the first circulation plate 10.

[0054] Furthermore, the plurality of first spoiler protrusions 15 can be arranged in an array or in an irregular arrangement, and this embodiment does not impose any restrictions on this, as long as the spoiler of the refrigerant is achieved. Similarly, the plurality of second spoiler protrusions can be arranged in an array or in an irregular arrangement, and this embodiment does not impose any restrictions on this, as long as the spoiler of the coolant is achieved.

[0055] Optionally, in an embodiment of the present application, the first body 14 includes a first side 141 and a second side 142 arranged opposite to each other along the length direction of the plate heat exchanger, one end of the first rib 11 is connected to the first side 141, and the other end of the first rib 11 and the second side 142 have a preset interval; the second body 24 includes a third side 241 and a fourth side 242 arranged opposite to each other along the length direction of the plate heat exchanger, one end of the second rib 21 is connected to the third side 241, and the other end of the second rib 21 and the fourth side 242 have a preset interval; wherein the first side 141 and the fourth side 242 overlap along the first direction, and the second side 142 and the third side 241 overlap along the first direction.

[0056] In the embodiment of the present application, the first rib 11 extends along the length of the first body 14. One end of the first rib 11 extends to the edge of the first body 14, namely, the first side 141. The other end of the first body 14 does not extend to the edge of the first body 14. In other words, there is a preset gap between the other end of the first body 14 and the second side 142. This preset gap is designed to provide a flow path for the refrigerant. Accordingly, the second rib 21 extends along the length of the second body 24. One end of the second rib 21 extends to the edge of the first body 14, namely, the third side 241. The other end of the second body 24 does not extend to the edge of the first body 14. In other words, there is a preset gap between the other end of the first body 14 and the fourth side 242. This preset gap is designed to provide a flow path for the coolant.

[0057] Furthermore, the preset interval between the first rib 11 and the second side 142, and the preset interval between the second rib 21 and the fourth side 242, are relatively arranged along the length direction of the plate heat exchanger. That is, in actual application, the flow directions of the refrigerant and the coolant are opposite, which has the beneficial effect of further improving the heat exchange efficiency.

[0058] Optionally, in an embodiment of the present application, the first body 14 is provided with a first inlet 143 and a first outlet 144, and the first inlet 143 and the first outlet 144 are arranged close to the first edge 141, and the first inlet 143 and the first outlet 144 are respectively arranged on both sides of the first rib 11, and the refrigerant flows into the refrigerant flow channel through the first inlet 143, and then flows out of the refrigerant flow channel through the first outlet 144.

[0059] Furthermore, the first body 14 further includes a first hole 145 and a second hole 146 . The first hole 145 and the second hole 146 are disposed near the second edge 142 . Both the first hole 145 and the second hole 146 extend along the first direction and are sealed to the fourth surface 23 .

[0060] In the embodiment of the present application, the refrigerant flows into the refrigerant flow channel through the first inlet 143 , bypasses the first rib 11 , flows from the preset gap between the first rib 11 and the second edge 142 to the first outlet 144 , and then flows out of the refrigerant flow channel through the first outlet 144 .

[0061] Furthermore, the first channel 145 and the second channel 146 are both sealedly connected to the fourth surface 23. The first channel 145 and the second channel 146 are provided to provide a flow channel for the coolant, for transferring the refrigerant in the adjacent refrigerant flow channels. However, due to the sealed connection with the fourth surface 23, the coolant does not enter the refrigerant flow channel, but flows into the coolant flow channel, thereby realizing the mutual independence between the coolant flow channel and the refrigerant flow channel.

[0062] Optionally, in an embodiment of the present application, the second body 24 is provided with a second inlet 243 and a second outlet 244, and the second inlet 243 and the second outlet 244 are arranged near the third side 241, and the second inlet 243 and the second outlet 244 are respectively arranged on both sides of the second rib 21, and the coolant flows into the coolant flow channel through the second inlet 243 and then flows out of the coolant flow channel through the second outlet 244.

[0063] Furthermore, the second body 24 also includes a third hole 245 and a fourth hole 246 . The third hole 245 and the fourth hole 246 are arranged near the fourth edge 242 . The third hole 245 and the fourth hole 246 both extend along the first direction and are sealed to the second surface 13 .

[0064] Furthermore, the first inlet 143 is communicated with the third channel 245 , the first outlet 144 is communicated with the fourth channel 246 , the first channel 145 is communicated with the second inlet 243 , and the second channel 146 is communicated with the second outlet 244 .

[0065] In the embodiment of the present application, the coolant flows into the coolant channel through the second inlet 243 , bypasses the second rib 21 , flows from the preset gap between the second rib 21 and the fourth edge 242 to the second outlet 244 , and then flows out of the coolant channel through the second outlet 244 .

[0066] Furthermore, the third channel 245 and the fourth channel 246 are both sealedly connected to the second surface 13. The third channel 245 and the fourth channel 246 are configured to provide a flow channel for the coolant, thereby transferring the coolant between adjacent coolant channels. However, due to the sealed connection to the fourth surface 23, the coolant does not enter the refrigerant channel, but instead flows into the coolant channel, thus achieving mutual independence between the coolant channel and the refrigerant channel. Furthermore, the first inlet 143 and the second inlet 243, as well as the first outlet 144 and the second outlet 244, are all connected to different channels. Therefore, the above configuration further separates the flow of coolant and refrigerant in the plate heat exchanger.

[0067] Optionally, in the embodiment of the present application, the plate heat exchanger further includes a spoiler 30 , which is sandwiched between the first circulation plate 10 and the second circulation plate 20 and is disposed in the coolant flow channel.

[0068] In the embodiment of the present application, the spoiler 30 is provided to disrupt the flow of the coolant within the coolant channel. In practical applications, the spoiler 30 is sandwiched between the first circulation plate 10 and the second circulation plate 20, disrupting the coolant flow within the coolant channel. Specifically, the spoiler 30 protrudes from the body and, further, abuts against the first circulation plate 10, further improving the reliability of the first circulation plate 10.

[0069] Furthermore, the flow deflector may be a plurality of parts or a single component, and this embodiment does not impose any limitation thereto. When the flow deflector 30 is a single component, the flow deflector should have corresponding openings corresponding to the second rib 21, the first inlet 143, the first outlet 144, the first channel 145, the second channel 146, the second inlet 243, the second outlet 244, the third channel 245, and the fourth channel 246 to prevent the flow deflector from blocking the aforementioned components and affecting the flow of the refrigerant and coolant.

[0070] Optionally, in an embodiment of the present application, a thermal management system is also provided, comprising the plate heat exchanger as described above.

[0071] In an embodiment of the present application, the vehicle includes the plate heat exchanger as described above, and further includes all the features and beneficial effects of the above-mentioned plate heat exchanger, which will not be described in detail in this embodiment.

[0072] Optionally, in an embodiment of the present application, a vehicle is also provided, comprising the thermal management system as described above.

[0073] In the embodiment of the present application, since the vehicle includes the thermal management system as described above, and thus also includes all the features and beneficial effects of the above-mentioned plate heat exchanger, this embodiment will not be described in detail here.

[0074] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
