Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and particularly to an expansion water tank, a cooling system having the same, and a vehicle. Background Art

[0002] The expansion water tank of a vehicle can supplement coolant for cooling circuits such as the battery circuit, the electric drive circuit, and the heater circuit of the vehicle at the same time. Since the coolant temperatures in different cooling circuits are different, the coolant in different cooling circuits will cause cross-heating in the expansion water tank, reducing the cooling efficiency of the expansion water tank.

[0003] For example, the expansion water tank is provided with a liquid replenishment port. The expansion water tank passes coolant into the cooling circuit through the liquid replenishment port, and then recovers the coolant in the cooling circuit. The temperature of the recovered coolant is relatively high. If it directly flows into other cooling circuits after passing through the liquid replenishment port, it will cause a phenomenon of reduced cooling efficiency or cooling failure. Summary of the Utility Model

[0004] The purpose of the present application is to at least solve the technical problem that cross-heating easily occurs in the liquid replenishment inside the existing expansion water tank, and this purpose is achieved through the following technical solutions:

The plurality of partition plates divide the liquid replenishment cavity of the tank body into a plurality of cooling chambers, and a channel is provided on the partition plate between two adjacent cooling chambers. The channel sequentially connects the plurality of cooling chambers and the plurality of liquid replenishment ports.

[0006] In some embodiments, the plurality of partition plates include a first partition plate and a plurality of second partition plates. The plurality of liquid replenishment ports include a first liquid replenishment port distributed on one side of the first partition plate and a second liquid replenishment port distributed on the other side of the first partition plate. The plurality of second partition plates are distributed on the side opposite to the first partition plate of the second liquid replenishment port. The plurality of channels of the plurality of second partition plates form a first circuitous flow path that迂回 from the second liquid replenishment port to the first liquid replenishment port.

[0007] In some embodiments, the plurality of partition plates further include a first cross-shaped partition plate that divides the inside of the tank body into a first cross-shaped chamber. The second liquid replenishment port and the first liquid replenishment port are respectively connected to the upper and lower chambers on the same side of the first cross-shaped chamber. The first circuitous flow path includes a reciprocating circuitous flow path that connects the second liquid replenishment port, the first liquid replenishment port, and the four chambers of the first cross-shaped chamber.

[0008] In some embodiments, the multiple partition plates include a third partition plate and multiple fourth partition plates. The third partition plate is distributed on the side opposite to the first partition plate with respect to the first liquid replenishing port. The multiple liquid replenishing ports further include a third liquid replenishing port distributed on the other side of the third partition plate. The multiple fourth partition plates are distributed on the side opposite to the third partition plate with respect to the third liquid replenishing port. The multiple channels of the multiple fourth partition plates form a second tortuous flow path that迂回至 from the third liquid replenishing port to the first liquid replenishing port.

[0009] In some embodiments, the multiple partition plates further include a second cross-shaped partition plate that divides the interior of the kettle body into a second cross-shaped chamber. The third liquid replenishing port and the first liquid replenishing port are respectively communicated with the upper and lower two chambers on the same side of the second cross-shaped chamber. The second tortuous flow path includes a reciprocating tortuous flow path that communicates the third liquid replenishing port, the first liquid replenishing port, and the four chambers of the second cross-shaped chamber.

[0010] In some embodiments, the second liquid replenishing port and the third liquid replenishing port are distributed on both sides of the first liquid replenishing port. The second liquid replenishing port, the third liquid replenishing port, and the first liquid replenishing port are close to the edge of the kettle body. A return groove is provided at the edge of the kettle body. The first liquid replenishing port is communicated with the middle of the return groove. The second liquid replenishing port and the third liquid replenishing port are respectively communicated to both ends of the return groove through the first cross-shaped chamber and the second cross-shaped chamber.

[0011] In some embodiments, the first cross-shaped chamber is provided with a first flow collecting channel opposite to the return groove. The multiple cooling chambers include a first confluence chamber communicated with the first flow collecting channel, and / or the second cross-shaped chamber is provided with a second flow collecting channel opposite to the return groove.

[0015] The expansion water kettle provided by the embodiments of the present application separates the liquid replenishing cavity through multiple partition plates and multiple cooling chambers, so that the high-temperature coolant in the expansion water kettle can be fully cooled by the kettle body and then replenished to the liquid replenishing port, improving the cooling effect of the expansion water kettle and reducing the phenomenon of heat transfer when the high-temperature coolant directly replenishes liquid outward through the liquid replenishing port.

[0016] Specifically, coolant is placed inside each of the multiple cooling chambers, and the high-temperature coolant that flows back to the expansion kettle passes through the low-temperature coolant in the multiple cooling chambers in turn, thereby achieving a step-by-step cooling effect. Compared with a single cooling chamber, multiple cooling chambers can maximize the heat exchange efficiency and reduce the phenomenon of uneven heat exchange of the low-temperature coolant in a cooling chamber. For example, the low-temperature coolant at the corner of a cooling chamber may not exchange heat, while the low-temperature coolant in the middle of a cooling chamber may have excessive heat exchange.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0029] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an", and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", and "have" are inclusive and therefore specify the presence of stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0030] Although the terms first, second, etc. may be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used. In addition, in the description of this application, unless otherwise clearly specified and limited, the terms "set" and "connect" 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 directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0031] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "outer", "end", "upper", "lower", "high", "lower", "inner", "middle", "side", "axial", "first direction", "second direction", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation in addition to the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will then be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0032] "Expansion kettle" refers to a device used to store coolant and provide coolant cooling to the vehicle's battery circuit, electric drive circuit, heating circuit, etc. The expansion kettle is provided with a fluid filling port, and the expansion kettle introduces coolant into the cooling circuit through the fluid filling port, so as to achieve the purpose of circulating cooling of the cooling circuit.

[0033] At present, in order to achieve the purpose of integrated design, expansion kettles often arrange multiple fluid inlets adjacent to each other. During actual use, the adjacent fluid inlets may have heat cross-talk. For example, high-temperature coolant passing through one fluid inlet directly flows through another fluid inlet to the cooling reflux. The high-temperature coolant has a poor cooling effect on the cooling circuit, which may cause cooling failure in the cooling circuit.

[0034] In order to solve the technical problem of heat transfer between replenishing fluids in related technologies, the expansion kettle provided in the present application separates the replenishing fluid chamber by multiple partitions and multiple cooling chambers, so that the high-temperature coolant in the expansion kettle can be fully cooled by the kettle body before being replenished to the replenishing fluid port, thereby improving the cooling efficiency of the expansion kettle.

[0035] Below through Figures 1 to 4 The expansion kettle according to the embodiment of the present application is described in detail.

[0036] like Figures 1 to 4 As shown, the present application provides an expansion kettle 100, including a kettle body 10, wherein the kettle body 10 is provided with a plurality of adjacently distributed liquid infusion ports, a liquid infusion cavity is formed around the plurality of liquid infusion ports, and a plurality of partitions are further provided inside the kettle body 10, wherein the plurality of partitions divide the interior of the kettle body 10 into a plurality of cooling chambers, and a partition between two adjacent cooling chambers is provided with a channel, which connects the plurality of cooling chambers with the plurality of liquid infusion ports in sequence.

[0037] In this embodiment, the expansion kettle 100 provided in the embodiment of the present application separates the fluid replenishing cavity by multiple partitions and multiple cooling chambers, so that the high-temperature coolant in the expansion kettle 100 can be fully cooled by the kettle body 10 and then replenished to the fluid replenishing port, thereby improving the cooling effect of the expansion kettle 100 and reducing the phenomenon of heat transfer caused by the high-temperature coolant directly replenishing to the outside through the fluid replenishing port.

[0038] Specifically, coolant is placed inside each of the multiple cooling chambers, and the high-temperature coolant flowing back to the expansion kettle 100 passes through the low-temperature coolant in the multiple cooling chambers in sequence, thereby achieving a step-by-step cooling effect. Compared with a single cooling chamber, multiple cooling chambers can maximize the heat exchange efficiency and reduce the phenomenon of uneven heat exchange of the low-temperature coolant in a cooling chamber. For example, the low-temperature coolant at the corner of a cooling chamber may not exchange heat, while the low-temperature coolant in the middle of a cooling chamber may have excessive heat exchange.

[0039] In addition, the embodiments of the present application do not limit the specific distribution and structure of the fluid infusion port, partition and cooling chamber because the main improvement of the present application is to connect the fluid infusion port through multiple cooling chambers. As long as the partitions and cooling chambers can achieve this effect, they belong to the protection scope of the embodiments of the present application. As for the specific distribution and structure of the fluid infusion port, partition and cooling chamber, multiple embodiments are included. Therefore, the embodiments of the present application do not limit this structure. Of course, in order to facilitate understanding of the technical solution of the present application, the present application will elaborate on the specific distribution and structure of the fluid infusion port, partition and cooling chamber through an embodiment described below.

[0040] It should be noted that the embodiments of the present application do not limit the number of fluid infusion ports because the number of fluid infusion ports can be flexibly set according to the usage scenario. For example, the number of fluid infusion ports can be set to two or three. These structures all fall within the protection scope of the embodiments of the present application and will not be elaborated one by one here.

[0041] The specific implementation of the expansion kettle 100 is described below through the preferred embodiment of the present application.

[0042] like Figures 1 to 4 As shown, in some embodiments, the multiple partitions include a first partition 11 and a plurality of second partitions 12, the multiple fluid infusion ports include a first fluid infusion port 101 distributed on a first side of the first partition 11, and a second fluid infusion port 102 distributed on a second side of the first partition 11, the multiple second partitions 12 are distributed on a side of the second fluid infusion port 102 opposite to the first partition 11, and the multiple channels of the multiple second partitions 12 form a first detour flow channel from the second fluid infusion port 102 to the first fluid infusion port 101.

[0043] In this embodiment, the first partition 11 separates the first liquid replenishing port 101 from the second liquid replenishing port 102, achieving the purpose of blocking the first liquid replenishing port 101 and the second liquid replenishing port 102, thereby reducing the phenomenon that the coolant flowing back to the expansion water tank 100 through the second liquid replenishing port 102 directly flows out through the first liquid replenishing port 101.

[0044] Specifically, multiple second partitions 12 play a guiding role for the coolant at the second liquid replenishing port 102 in the expansion water tank 100, enabling the high-temperature coolant at the second liquid replenishing port 102 to be sufficiently cooled in the expansion water tank 100 and then flow into the component to be cooled through the first liquid replenishing port 101, thereby achieving the effect of effectively cooling the component to be cooled.

[0045] As Figures 1 to 4 shown, in some embodiments, the multiple partitions further include a first cross-shaped partition that divides the interior of the kettle body 10 into a first cross-shaped chamber 15. The second liquid replenishing port 102 and the first liquid replenishing port 101 are respectively connected to the upper and lower two chambers on the same side of the first cross-shaped chamber 15. The first return flow channel includes a reciprocating return flow channel that connects the second liquid replenishing port 102, the first liquid replenishing port 101, and the four chambers of the first cross-shaped chamber 15.

[0046] In this embodiment, the first cross-shaped chamber 15 has four cooling chambers, and coolant is placed inside all four cooling chambers. The high-temperature coolant flowing back to the expansion water tank 100 through the second liquid replenishing port 102 sequentially passes through the low-temperature coolant in the four cooling chambers, thereby achieving the effect of step-by-step temperature reduction.

[0047] Specifically, compared with a single cooling chamber, the four cooling chambers can maximize the heat exchange efficiency and reduce the phenomenon of uneven heat exchange of the low-temperature coolant in a single cooling chamber. For example, the low-temperature coolant at the corners in a single cooling chamber may not be heat-exchanged, while the low-temperature coolant in the middle of a single cooling chamber may be over-heat-exchanged.

[0048] Furthermore, the distribution mode of the second liquid replenishing port 102 and the first liquid replenishing port 101 and the reciprocating return flow channel are beneficial to improving the layout compactness of the internal cooling chambers and partitions of the expansion water tank 100 and reducing the phenomenon that the flow path of the coolant in the expansion water tank 100 additionally increases the volume of the expansion water tank 100.

[0049] As Figures 1 to 4As shown, in some embodiments, the multiple partition plates include a third partition plate 13 and multiple fourth partition plates 14. The third partition plate 13 is distributed on the side of the first liquid filling port 101 opposite to the first partition plate 11. The multiple liquid filling ports further include a third liquid filling port 103 distributed on the other side of the third partition plate 13. The multiple fourth partition plates 14 are distributed on the side of the third liquid filling port 103 opposite to the third partition plate 13. The multiple channels of the multiple fourth partition plates 14 form a second circuitous flow path that迂回 from the third liquid filling port 103 to the first liquid filling port 101.

[0050] In this embodiment, by setting the third liquid filling port 103 on the other side of the first liquid filling port 101, the utilization rate of the expansion water tank 100 can be improved. Specifically, the second liquid filling port 102 and the third liquid filling port 103 of the expansion water tank 100 are respectively used to communicate with different components in the vehicle. For example, the second liquid filling port 102 communicates with the battery circuit of the vehicle, and the third liquid filling port 103 communicates with the electric drive circuit or the warm air circuit of the vehicle. Through the two liquid filling ports, the circulating return liquid of different components to be cooled in the vehicle is achieved.

[0051] In addition, a three-way valve or a four-way valve can be provided at the first liquid filling port 101. The expansion water tank 100 controls the coolant to be filled and cooled to different components to be cooled through the three-way valve or the four-way valve, thereby improving the applicable efficiency of the expansion water tank 100.

[0052] As Figures 1 to 4 shown, in some embodiments, the multiple partition plates further include a second cross-shaped partition plate that partitions the interior of the kettle body 10 into a second cross-shaped chamber 16. The third liquid filling port 103 and the first liquid filling port 101 are respectively communicated with the upper and lower two chambers on the same side of the second cross-shaped chamber 16. The second circuitous flow path includes a reciprocating circuitous flow path that communicates the third liquid filling port 103, the first liquid filling port 101, and the four chambers of the second cross-shaped chamber 16.

[0053] In this embodiment, the implementation manner and technical effect of the second cross-shaped chamber 16 are similar to those of the first cross-shaped chamber 15. Specifically, the second cross-shaped chamber 16 has four cooling chambers, and coolant is placed in each of the four cooling chambers. The high-temperature coolant that returns to the expansion water tank 100 through the third liquid filling port 103 sequentially passes through the low-temperature coolant in the four cooling chambers, thereby achieving the effect of step-by-step cooling.

[0054] Furthermore, compared with the reciprocating circuitous flow path of the first cross-shaped chamber 15, the flow path directions of the two are different, so that the second cross-shaped chamber 16 and the first cross-shaped chamber 15 can be staggered relative to the first liquid filling port 101, which is beneficial to improving the layout compactness of the cooling chambers and partition plates inside the expansion water tank 100, and reducing the phenomenon that the flow path of the coolant in the expansion water tank 100 is additionally increased to increase the volume of the expansion water tank 100.

[0055] like Figures 1 to 4 As shown, in some embodiments, the second liquid infusion port 102 and the third liquid infusion port 103 are distributed on both sides of the first liquid infusion port 101, the second liquid infusion port 102, the third liquid infusion port 103 and the first liquid infusion port 101 are close to the edge of the kettle body 10, and a reflux groove 17 is provided on the edge of the kettle body 10. The first liquid infusion port 101 is connected to the middle part of the reflux groove 17, and the second liquid infusion port 102 and the third liquid infusion port 103 are connected to the two ends of the reflux groove 17 through the first field-shaped chamber 15 and the second field-shaped chamber 16 respectively.

[0056] In this embodiment, by distributing the second fluid infusion port 102 and the third fluid infusion port 103 on both sides of the first fluid infusion port 101, the purpose of centrally arranging the second fluid infusion port 102, the third fluid infusion port 103 and the first fluid infusion port 101 can be achieved, thereby reducing the structural improvement of the expansion kettle 100 and reducing the manufacturing cost of the expansion kettle 100.

[0057] Specifically, a larger flow opening can be provided on the kettle body 10 of the expansion kettle 100, and then the first partition 11, the second partition 12, the third partition 13 and the fourth partition 14 are provided at intervals at the flow opening, so that the three gaps formed between the first partition 11, the second partition 12, the third partition 13 and the fourth partition 14 form three small flow openings, and the three small flow openings respectively form the first fluid replenishment port 101, the second fluid replenishment port 102 and the third fluid replenishment port 103.

[0058] Further, by placing the second liquid inlet 102, the third liquid inlet 103 and the first liquid inlet 101 close to the edge of the kettle body 10, the interference effect of the second liquid inlet 102, the third liquid inlet 103 and the first liquid inlet 101 on other structures in the expansion kettle 100 can be reduced. For example, the interference effect of the second liquid inlet 102, the third liquid inlet 103 and the first liquid inlet 101 on the kettle cover 30 of the expansion kettle 100 can be reduced, so that the kettle cover 30 of the expansion kettle 100 can be normally distributed in the middle of the expansion kettle 100. In addition, by placing the second liquid inlet 102, the third liquid inlet 103 and the first liquid inlet 101 close to the edge of the kettle body 10, the second liquid inlet 102, the third liquid inlet 103 and the first liquid inlet 101 can also share a reflux groove 17, thereby reducing the number of reflux grooves 17 inside the expansion kettle 100 and reducing the difficulty of arranging the reflux grooves 17.

[0059] like Figures 1 to 4As shown, in some embodiments, the first cross-shaped chamber 15 is provided with a first collecting channel 181 opposite to the reflux groove 17. The plurality of cooling chambers include a first confluence chamber 18 communicating with the first collecting channel 181, and / or the second cross-shaped chamber 16 is provided with a second collecting channel 191 opposite to the reflux groove 17. The plurality of cooling chambers include a second confluence chamber 19 communicating with the second collecting channel 191.

[0060] In this embodiment, by providing a first collecting channel 181 and a first confluence chamber 18 communicating with the first cross-shaped chamber 15 inside the expansion water kettle 100, when the first cross-shaped chamber 15 has insufficient liquid supply, the coolant in the first confluence chamber 18 can flow to the first cross-shaped chamber 15 through the first collecting channel 181, and then replenish the first liquid replenishing port 101 through the first cross-shaped chamber 15, thereby reducing the phenomenon of insufficient liquid replenishment at the first liquid replenishing port 101, enabling the expansion water kettle 100 to timely supply coolant to the component to be cooled through the first liquid replenishing port 101.

[0061] Similarly, by providing a second collecting channel 191 and a second confluence chamber 19 communicating with the second cross-shaped chamber 16 inside the expansion water kettle 100, when the second cross-shaped chamber 16 has insufficient liquid supply, the coolant in the second confluence chamber 19 can flow to the second cross-shaped chamber 16 through the second collecting channel 191, and then replenish the first liquid replenishing port 101 through the second cross-shaped chamber 16, thereby reducing the phenomenon of insufficient liquid replenishment at the first liquid replenishing port 101, enabling the expansion water kettle 100 to timely supply coolant to the component to be cooled through the first liquid replenishing port 101.

[0062] It should be noted that the embodiments of the present application do not limit the positional relationship among the confluence chambers (including the first and second confluence chambers), the collecting channels (including the first and second collecting channels), and the cross-shaped chambers (including the first and second cross-shaped chambers) because the positional relationship among the confluence chambers, the collecting channels, and the cross-shaped chambers needs to be flexibly set according to the placement state of the expansion water kettle 100 and the actual use scenario.

[0063] For example, as Figure 4 shown, during the actual use of the expansion water kettle 100, it is likely to tilt downward at the front side (L is the horizontal plane). At this time, the confluence chamber and the collecting channel need to be arranged at the rear side of the cross-shaped chamber, so that when the expansion water kettle 100 tilts downward at the front side, the coolant in the confluence chamber at the rear side can flow to the cross-shaped chamber at the front side, and then flow to the first liquid replenishing port 101 through the cross-shaped chamber to supply liquid to the component to be cooled, thereby improving the working reliability of the expansion water kettle 100.

[0064] Similarly, in some cases, the confluence chamber and the collecting channel can also be arranged on the left and right sides of the field-shaped chamber. These embodiments all fall within the protection scope of the present application and will not be elaborated one by one here.

[0065] like Figures 1 to 4 As shown, in some embodiments, the plurality of partitions include high partitions and low partitions of different heights, the plurality of high partitions enclose a first field-shaped chamber 15 and a second field-shaped chamber 16, and the plurality of low partitions form a circuitous flow channel and a collecting channel.

[0066] In the present embodiment, different cooling chambers are formed by enclosing a plurality of high partitions, so as to store coolant in different areas inside the expansion kettle 100, thereby achieving the purpose of gradually cooling the returning high-temperature coolant; a detour flow channel and a collecting channel are enclosed by a plurality of low partitions, and the high-temperature coolant inside the expansion kettle 100 is drained to different cooling chambers through the detour flow channel, thereby achieving the purpose of gradually cooling the returning high-temperature coolant; a collecting channel is enclosed by a plurality of low partitions, and the coolant inside the expansion kettle 100 is drained to the first liquid replenishment port 101 through the collecting channel, thereby reducing the phenomenon of insufficient liquid supply at the first liquid replenishment port 101.

[0067] Specifically, the embodiment of the present application proposes that the cooling and drainage effects can be achieved through multiple partitions of different heights, thereby reducing the structural improvements in the expansion kettle 100, and improving the performance of the expansion kettle 100 without affecting the overall molding structure and cost of the expansion kettle 100.

[0068] A second aspect of the present application provides a cooling system, comprising a component to be cooled and an expansion kettle 100 according to the first aspect of the present application, wherein the expansion kettle 100 is connected to the component to be cooled via a liquid infusion port.

[0069] In this embodiment, the cooling system proposed in the embodiment of the present application has all the technical effects of the expansion kettle 100, which will not be elaborated in detail here.

[0070] A third aspect of the present application provides a vehicle, comprising the cooling system according to the second aspect of the present application.

[0071] In this embodiment, the vehicle proposed in the embodiment of the present application has all the technical effects of the expansion kettle 100 and the cooling system, which will not be elaborated in detail here.

[0072] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.

[0073] In addition, the embodiments of the present application only illustrate the structures of the expansion kettle 100 related to the improvement points of the present application, and do not mean that the expansion kettle 100 of the present application does not have other structures. For example, the expansion kettle 100 also includes a driving device such as a water pump connected to the liquid infusion port, and also includes a pressure plate 40 arranged in the kettle body 10, an upper cover 20 snapped to the kettle body 10, and a kettle cover 30 arranged at the kettle mouth of the upper cover 20. These structures all belong to the protection scope of the expansion kettle 100 of the embodiments of the present application, and other structures of the expansion kettle 100 will not be described one by one here.

[0074] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
