Description

TECHNICAL FIELD

[0001] The utility model relates to heat management technical field especially relates to a heat exchanger for vehicle. BACKGROUND

[0002] The plate heat exchanger comprises a plurality of stacked plates, and the adjacent plates form inter-plate channels for fluid flow. Two fluids can flow on both sides of the plates to realize wall heat exchange through the plates.

[0003] In the related art, the plate heat exchanger has a heat exchange core and a mounting base. The heat exchange core is mounted on the vehicle body through the mounting base. Before leaving the factory, the heat exchange core and the mounting base need to be assembled into an integrated structure. The assembly of the heat exchange core and the mounting base affects the production efficiency of the product, so a positioning method needs to be designed to improve the assembly efficiency of the heat exchange core and the mounting base. SUMMARY

[0004] The applicant found during actual assembly that because the first positioning column and the second positioning column are located on the fitting surface between the heat exchange core and the mounting plate, the assembly personnel cannot observe the specific position of the first positioning column and the second positioning column, and need to move the heat exchange core or the mounting plate until the first positioning column and the first positioning hole are matched and the second positioning column and the second positioning hole are matched, which is relatively low in assembly efficiency. It is necessary to provide a heat exchanger capable of improving the assembly efficiency in view of the above problems.

[0005] The technical scheme adopted by the utility model is as follows: a heat exchanger, comprising a heat exchange core and a mounting plate; one of the heat exchange core and the mounting plate has at least one first positioning hole, and the other of the heat exchange core and the mounting plate has at least one first positioning column, and at least part of the first positioning column is located in the first positioning hole;

[0006] One of the heat exchange core and the mounting plate also has at least one second positioning hole, and the other of the heat exchange core and the mounting plate has at least one second positioning column, and at least part of the second positioning column is located in the second positioning hole;

[0007] The first positioning hole extends along a first direction X, and the extension length of the first positioning hole along the first direction X is greater than the extension length of the first positioning column along the first direction X; the first positioning hole can limit the relative position of the first positioning column and the first positioning hole in a second direction Y, and the first direction X and the second direction Y intersect;

[0008] The second positioning hole can limit the relative position of the second positioning column and the second positioning hole in the first direction X.

[0009] The first positioning post of this application is located in the first positioning hole, and the second positioning post is located in the second positioning hole. Since the first positioning hole can restrict the relative position of the first positioning post and the first positioning hole in the second direction Y, and the second positioning hole can restrict the relative position of the second positioning post and the second positioning hole in the first direction X, that is, the movement of the first positioning post in the first positioning hole along the first direction X is restricted, and the movement of the second positioning post in the second positioning hole along the second direction Y is restricted, and the first direction X and the second direction Y intersect, thereby realizing the assembly of the heat exchange core and the mounting plate. Since the first positioning hole extends along the first direction X, and the extension length of the first positioning hole along the first direction X is greater than the extension length of the first positioning post along the first direction X, moving the heat exchange core can improve the matching probability of the first positioning post and the first positioning hole, thereby improving the installation efficiency of both the heat exchange core and the mounting plate.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail with the help of the drawings. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0027] As Figures 1-3 shown, the heat exchanger 1, including heat exchange core body 2 and mounting plate 3, heat exchange core body 2 has first inlet 4 and first outlet 5, and first fluid enters heat exchange core body 2 through first inlet 4, and then flows out from first outlet 5, heat exchange core body 2 also has second inlet 6 and second outlet 7, and second fluid enters heat exchange core body 2 through second inlet 6, and then flows out from second outlet 7, first fluid and second fluid realize wall heat exchange through the sheet of heat exchange core body 2. In actual application, heat exchange core body 2 is assembled to the vehicle body through mounting plate 3. Mounting plate 3 has a plurality of through holes 8, and the plurality of through holes 8 are respectively matched with first inlet 4, first outlet 5, second inlet 6 and second outlet 7, and fluid can enter and exit heat exchange core body 2 through these through holes 8 of mounting plate 3.

[0028] As shown in Figures 3-6 One of the heat exchange core 2 and the mounting plate 3 has at least one first positioning hole 9, and the other of the heat exchange core 2 and the mounting plate 3 has at least one first positioning column 10, at least part of the first positioning column 10 is located in the first positioning hole 9; one of the heat exchange core 2 and the mounting plate 3 also has at least one second positioning hole 11, and the other of the heat exchange core 2 and the mounting plate 3 has at least one second positioning column 12, at least part of the second positioning column 12 is located in the second positioning hole 11; the first positioning hole 9 extends along the first direction X, and the extension length of the first positioning hole 9 along the first direction X is greater than the extension length of the first positioning column 10 along the first direction; the first positioning hole 9 can limit the relative position of the first positioning column 10 and the first positioning hole 9 in the second direction Y, and the first direction and the second direction intersect; the second positioning hole 11 can limit the relative position of the second positioning column 12 and the second positioning hole 11 in the first direction X. Assembly of the heat exchange core 2 and the mounting plate 3: move the heat exchange core 2, after the first positioning column 10 is located in the first positioning hole 9, the heat exchange core 2 can be moved along the first direction X until the second positioning column 12 is located in the second positioning hole 11; because the first positioning hole 9 can limit the relative position of the first positioning column 10 and the first positioning hole 9 in the second direction Y, the second positioning hole 11 can limit the relative position of the second positioning column 12 and the second positioning hole 11 in the first direction X, and the first direction and the second direction intersect, thus the movement of the heat exchange core 2 can be limited, thereby realizing the assembly of the two; the first positioning hole 9 of the present application extends along the first direction X, and the extension length of the first positioning hole 9 along the first direction X is greater than the extension length of the first positioning column 10 along the first direction, when moving the heat exchange core 2, the coordination probability of the first positioning column 10 and the first positioning hole 9 can be improved, thereby the installation efficiency of the heat exchange core 2 and the mounting plate 3 can be improved.

[0029] In the above technical solution, as shown in Figure 5 For example, the first positioning column 10 and the second positioning column 12 can be arranged on the mounting plate 3 at the same time, and correspondingly, the first positioning hole 9 and the second positioning hole 11 are arranged on the heat exchange core 2; of course, the first positioning column 10 can be arranged on the heat exchange core 2, and the second positioning column 12 can be arranged on the mounting plate 3, and correspondingly, the first positioning hole 9 is arranged on the mounting plate 3, and the second positioning column 12 is arranged on the heat exchange core 2. Further, the first positioning column 10 and the second positioning column 12 are arranged on the mounting plate 3 or the heat exchange core 2 at the same time, which is convenient for processing.

[0030] As shown in Figure 6As shown, one of the heat exchange core 2 and the mounting plate 3 has at least two first positioning holes 9, and the other of the heat exchange core 2 and the mounting plate 3 has at least two first positioning posts 10. Thus, with the two first positioning posts 10 located behind the two first positioning holes 9, rotation of the heat exchange core 2 can be prevented, thereby increasing the matching probability of the second positioning post 12 and the second positioning hole 11, and further improving the installation efficiency of both the heat exchange core and the mounting plate 3. The number of second positioning holes 11 can be one or more.

[0031] There are no particular restrictions on the shape of the first positioning hole 9, as long as the first positioning hole 9 extends along the first direction and allows the first positioning post 10 to move within the first positioning hole 9 along the first direction. For example, ... Figures 6-7 As shown, the first positioning hole 9 is an oblong or arc-shaped hole. Thus, after the first positioning post 10 is located in the first positioning hole 9, it can slide along the extension path of the oblong hole until the second positioning post 12 is located in the second positioning hole 11, thereby realizing the installation of the heat exchange core 2 and the mounting plate 3.

[0032] like Figure 8 As shown, the second positioning hole 11 is an oblong or arc-shaped hole, and the second positioning hole 11 extends along the second direction, and the extension length of the second positioning hole 11 along the second direction is greater than the extension length of the second positioning post 12 along the second direction. If the second positioning hole 11 is a circular hole, in order to meet the matching of the second positioning post 12 and the second positioning hole 11, the machining accuracy of the second positioning hole 11 is required to be high; in this embodiment, the second positioning hole 11 is designed as an oblong or arc-shaped hole, which can greatly reduce the machining accuracy and thus improve the product qualification rate.

[0033] like Figures 2-6 As shown, the heat exchange core 2 has a first side 13 and a second side 14, which are arranged opposite to each other. Two sets of first positioning holes 9 are provided, one set located on the first side 13 of the heat exchange core 2 and the other set located on the second side 14. A second positioning hole 11 is located between the two sets of first positioning holes 9. Thus, during assembly, the heat exchange core 2 can be moved from the first side 13 towards the second side 14 until the first positioning post 10 and the first positioning hole 9, as well as the second positioning post 12 and the second positioning hole 11, are aligned; or, during assembly, the heat exchange core 2 can also be moved from the second side 14 towards the first side 13 until the first positioning post 10 and the first positioning hole 9, as well as the second positioning post 12 and the second positioning hole 11, are aligned.

[0034] like Figure 5 As shown, the first positioning post 10 is formed by stamping, and the second positioning post 12 is also formed by stamping. The fact that the first positioning post 10 and the second positioning post 12 are formed by stamping makes them easy to process and can improve production efficiency.

[0035] As shown in Figure 5 , the height of the first positioning column 10 is less than the height of the second positioning column 12; or, the height of the first positioning column 10 is greater than the height of the second positioning column 12. Thus, when the height of the first positioning column 10 is greater than the height of the second positioning column 12, after the heat exchange core 2 is attached to the mounting plate 3, since the height of the first positioning column 10 is greater than the height of the second positioning column 12, the first positioning column 10 is attached to the surface of the mounting plate 3, and the second positioning column 12 is not in contact with the surface of the mounting plate 3. In the process of moving the heat exchange core 2, the first positioning column 10 is preferentially positioned in the first positioning hole 9, and the heat exchange core 2 is moved in the first direction. When the second positioning column 12 is located in the second positioning hole 11, the second positioning hole 11 limits the movement of the second positioning column 12 in the first direction X, thereby realizing the assembly of the heat exchange core 2 and the mounting plate 3. When the height of the second positioning column 12 is greater than the height of the first positioning column 10, after the heat exchange core 2 is attached to the mounting plate 3, since the height of the second positioning column 12 is greater than the height of the first positioning column 10, the second positioning column 12 is attached to the surface of the mounting plate 3, and the first positioning column 10 is not in contact with the surface of the mounting plate 3. In the process of moving the heat exchange core 2, the second positioning column 12 is preferentially positioned in the second positioning hole 11, and the heat exchange core 2 is moved in the second direction. When the first positioning column 10 is located in the first positioning hole 9, the first positioning hole 9 limits the movement of the first positioning column 10 in the second direction, thereby realizing the assembly of the heat exchange core 2 and the mounting plate 3.

[0036] As shown in Figures 6-14 , the first positioning hole 9 is a waist-shaped hole, and the cross section of the first positioning column 10 is circular, elliptical or square; the second positioning hole 11 is a waist-shaped hole, and the cross section of the second positioning column 12 is circular, elliptical or square. Thus, when the cross sections of the first positioning column 10 and the second positioning column 12 are circular, in the process of moving the heat exchange core 2, the cross sections of the first positioning column 10 and the second positioning column 12 are circular, and the first positioning column 10 and the second positioning column 12 are easily positioned in the first positioning hole 9 and the second positioning hole 11, respectively. When one of the heat exchange core 2 and the mounting plate 3 has one first positioning hole 9, the other of the heat exchange core 2 and the mounting plate 3 has one first positioning column 10, one of the heat exchange core 2 and the mounting plate 3 has one second positioning hole 11, and the other of the heat exchange core 2 and the mounting plate 3 has one second positioning column 12, the cross section of the positioning column is elliptical or square, which can limit the rotation of the first positioning column 10 in the first positioning hole 9, thereby facilitating the positioning of the second positioning column 12 and the second positioning hole 11.

[0037] It should be noted that the shapes and numbers of the first positioning hole 9 and the second positioning hole 11, and the shapes and numbers of the first positioning column 10 and the second positioning column 12 can have multiple combinations. For example, Figure 10As shown, the first positioning hole 9 has two sets, each set having two first positioning holes 9, and the first positioning hole 9 is an oblong hole, the second positioning hole 11 is circular, and the cross-section of the first positioning post 10 and the second positioning post 12 is circular; or, as Figure 11 As shown, the first positioning hole 9 has two sets, each set having two first positioning holes 9, and both first positioning holes 9 are oblong holes. The cross-section of the first positioning post 10 is elliptical, the second positioning hole 11 is oblong, and the cross-section of the second positioning post 12 is circular; or, as... Figure 12 As shown, the first positioning hole 9 has two sets, each set having two first positioning holes 9, and both first positioning holes 9 are oblong holes. The cross-section of the first positioning post 10 is circular, the second positioning hole 11 is oblong, and the cross-section of the second positioning post 12 is elliptical; or, as Figure 13 As shown, the first positioning hole 9 has two sets, each set having one first positioning hole 9, and the first positioning hole 9 is an oblong hole. The cross-section of the first positioning post 10 is elliptical, the second positioning hole 11 is a round hole, and the cross-section of the second positioning post 12 is circular.

[0038] like Figures 2-6 As shown, the heat exchange core 2 includes a base plate 15, which has a first positioning hole 9 and a second positioning hole 11. The mounting plate 3 has a first positioning post 10 and a second positioning post 12. Thus, the base plate 15 is relatively thinner than the mounting plate 3, making it easier to punch holes in. Furthermore, since the mounting plate 3 has a sealing area 16, punching holes in the base plate 15 instead of the mounting plate 3 reduces damage to the sealing area 16 of the mounting plate 3. More specifically, the base plate 15 has two sets of first positioning holes 9, with two holes in each set. One set of first positioning holes 9 is located on the first side 13 of the heat exchange core 2, and the other set is located on the second side 14 of the heat exchange core 2. Simultaneously, the base plate 15 also has a second positioning hole 11 located between the two sets of first positioning holes 9. Correspondingly, the mounting plate 3 has two first positioning posts 10 and two positioning posts 12. Two first positioning posts 10 are located in the first positioning hole 9, and the second positioning post 12 is located in the second positioning hole 11, thereby realizing the assembly of the heat exchange core 2 and the mounting plate 3.

[0039] like Figures 2-6As shown, the heat exchange core 2 includes a first side 17, which extends in a straight line; the extension direction of the first side 17 is perpendicular to a first direction; the mounting plate 3 has a second side 18, which also extends in a straight line. The first side 17 of the heat exchange core 2 and the second side 18 of the mounting plate 3 are located on the same side of the heat exchange core 2. Typically, the heat exchange core 2 is square. The straight extension of the first side 17 of the heat exchange core 2 facilitates the alignment of the first positioning post 10 and the first positioning hole 9 by using the first side 17 as a reference.

[0040] like Figure 15 As shown, the mounting plate 3 has a sealing area 16, with the first positioning post 10 and the second positioning post 12 offset from the sealing area 16. In actual use, the sealing area 16 of the mounting plate 3 is generally fixed. If the positioning posts are placed in the sealing area 16, the sealing area of ​​the sealing area 16 will be reduced, thus affecting the sealing effect. The first positioning post 10 and the second positioning post 12 are formed by stamping, and the offsetting of the first positioning post 10 and the second positioning post 12 from the sealing area 16 can reduce damage to the sealing area 16.

[0041] The above-described embodiments are merely examples of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications without departing from the concept of this utility model, and these modifications all fall within the protection scope of this utility model.
