Description

Technical Field

[0001] The present application relates to the technical field of heat exchange equipment, and in particular to an intercooler and a mainboard thereof. Background Art

[0002] The mainboard of the intercooler is a component used to connect the chamber body and the core body of the intercooler. The mainboard is generally mounted on the shell of the core body and welded to the shell. At the same time, the mainboard is buckled with the chamber body through the buckle teeth on the mainboard to achieve a sealed connection between the mainboard, the core body and the chamber body. In the actual production process, it is found that after the mainboard and the shell are welded, a gap sometimes occurs between the mainboard and the shell, causing the pressurized air to leak into the atmosphere through the gap during the use of the intercooler, resulting in air leakage problems. Summary of the invention

[0003] The purpose of the present application is to provide an intercooler and its mainboard to address the problem that, after the mainboard and the outer shell are welded, a gap sometimes occurs between the mainboard and the outer shell, causing compressed air to leak into the atmosphere through the gap during use of the intercooler, resulting in air leakage.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] One aspect of the present application provides a main board of an intercooler, which is used to connect the core and chamber of the intercooler; the main board includes a first main body and a second main body, the first main body has a first end, the second main body has a second end, the first end is overlapped with the second end so that the first end and the second end can be movably matched, and the first main body and the second main body form a through channel for the core to pass through the main board and extend into the chamber.

[0006] Optionally, the first main body has two first ends, the second main body has two second ends, the two first ends are connected to the two second ends in a one-to-one correspondence, and the two first ends are used to be arranged on opposite sides of the core.

[0007] The beneficial effect of this technical solution is that during the brazing process, the movement between the first main body and the second main body can be properly guided by the cooperation between the two first ends and the two second ends, so that the positional relationship between the relevant components of the intercooler after brazing is completed is relatively accurate, thereby improving the quality of the product.

[0008] Optionally, the first end has a first sealing surface facing the chamber body, a positioning groove is formed on the first sealing surface, and the first end cooperates with the second end through the positioning groove to achieve overlapping of the first end and the second end.

[0009] The beneficial effect of this technical solution is that the second end cooperates with the positioning groove structure to limit the range of relative movement between the first end and the second end to a certain extent during the brazing process, so that the intercooler has a higher assembly accuracy.

[0010] Optionally, the positioning groove is a U-shaped groove, the second end has a protruding section that cooperates with the U-shaped groove, and the cross-section of the protruding section is U-shaped.

[0011] The beneficial effect of this technical solution is that through the cooperation of the U-shaped groove and the U-shaped segment, the relative position and relative movement range of the first end and the second end can be limited from multiple directions, further improving the assembly accuracy of the intercooler.

[0012] Optionally, the second end has a second sealing surface facing the chamber body, and the first sealing surface and the second sealing surface are located in the same plane.

[0013] The beneficial effect of this technical solution is that after the first main body is connected to the second main body, it is necessary to seal and connect with the chamber body through the first sealing surface and the second sealing surface. The ports of the current chamber body used to cooperate with the main board are mostly relatively regular rectangular shapes, and irregular structures such as step structures are usually not formed on the ports. Therefore, making the first sealing surface and the second sealing surface located in the same plane is beneficial to the sealing cooperation between the two sealing surfaces and the ports of the chamber body.

[0014] Optionally, the positioning groove has a positioning wall arranged facing the second main body, a sealing protrusion is formed on the positioning wall, and a receiving groove cooperating with the sealing protrusion is formed on the end surface of the second end.

[0015] The beneficial effects of this technical solution are: by setting a structure in which a sealing protrusion and a receiving groove cooperate, on the one hand, the sealing protrusion can effectively block the pressurized air entering the brazing pore, thereby reducing the leakage of the pressurized air when leakage occurs; on the other hand, when the first end and the second end produce relative movement perpendicular to the through channel, the size of the gap between the positioning wall and the end face of the second end may change significantly, while the size of the gap between the sealing protrusion and the walls of the receiving groove on both sides of the sealing protrusion remains almost unchanged or changes very little, which enables the flux to better fill the gap, thereby enabling better welding and sealing effects to be obtained at least at the position where the sealing protrusion and the receiving groove are provided.

[0016] Optionally, the sealing protrusion is a triangular protrusion, so that one side of the triangle is formed on the positioning wall, the shape of the receiving groove corresponds to the shape of the sealing protrusion, and the size of the receiving groove corresponds to the size of the sealing protrusion.

[0017] The beneficial effect of this technical solution is that the sealing protrusion is a triangular protrusion, and the receiving groove is designed accordingly, so that at least one side of the triangular protrusion is inclined relative to the direction of movement of the first end relative to the second end, so that there is almost no friction between the edge and the inner wall of the receiving groove, thereby reducing the hindrance to the relative movement of the first end and the second end caused by the cooperation between the sealing protrusion and the receiving groove.

[0018] Optionally, the main board includes a plurality of buckles for fixing the chamber body, and the position where the first end cooperates with the second end is located between two adjacent buckles.

[0019] The beneficial effect of this technical solution is that: in this way, the position where the main board is disconnected to form the first main body and the second main body will not be located at the position of the buckle, thereby reducing the difficulty of manufacturing the main board and avoiding affecting the buckle press chamber body.

[0020] Another aspect of the present application provides an intercooler, including a chamber body and a core body, the intercooler also includes the above-mentioned main board, the main board is sleeved on the core body, and the first end is sealed and connected to the second end.

[0021] The intercooler provided in the embodiment of the present application adopts the main board of the intercooler provided in the embodiment of the present application. Since the first main body and the second main body are overlapped by the first end and the second end, the relative positions of the first main body and the second main body can adapt to the size of the core body, and the positions of the first main body and the second main body can adapt to the changes in the size of the core body during the brazing process, so that better sealing can be achieved between the main board and the core body, reducing the possibility of a gap between the outer shell of the core body and the main board.

[0022] Optionally, the intercooler provided in the embodiment of the present application further includes a sealing ring; the first main body has a first sealing surface arranged facing the chamber body, the second main body has a second sealing surface arranged facing the chamber body, the first sealing surface and the second sealing surface are located in the same plane, and the sealing ring is located between the chamber body, the first sealing surface and the second sealing surface, so as to realize static sealing by squeezing the sealing ring through the chamber body, the first sealing surface and the second sealing surface.

[0023] The technical solution provided by this application can achieve the following beneficial effects:

[0024] The intercooler and its main board provided by the present application, when the main board and the core are assembled, the first main body and the second main body are respectively placed on the upper and lower sides of the core, and the first end and the second end are overlapped to enclose a through channel between the first main body and the second main body, and the first main body and the second main body, or the first end and the second end, can produce relative movement at least in a direction perpendicular to the through channel. The core is located in the through channel and is close to the first main body and the second main body. Since the first end and the second end are overlapped, the relative position between the first end and the second end can be adjusted within a certain range, thereby adapting to cores of different heights caused by dimensional tolerances. Moreover, during the brazing process, as the size of the core changes, the relative position between the first end and the second end can also be changed accordingly within a certain range, thereby making the first main body and the second main body better fit between the outer shell of the core, reducing the possibility of a gap between the outer shell of the core and the main board.

[0049] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0051] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] like Figures 1 to 6 As shown, one aspect of the present application provides a main board 100 of an intercooler, wherein the main board 100 is used to connect the core 200 and the chamber body of the intercooler; the main board 100 includes a first main body 120 and a second main body 110, the first main body 120 has a first end 121, the second main body 110 has a second end 111, the first end 121 overlaps the second end 111 so that the first end 121 and the second end 111 can be movably matched, and the first main body 120 and the second main body 110 enclose a through channel 130 for the core 200 to pass through the main board 100 and extend into the chamber body.

[0053] After repeated tests and research, it was found that the reasons for the gap between the main board 100 and the shell of the core 200 after brazing during the intercooler production process are roughly as follows:

[0054] (1) The core 200 is composed of stacked heat exchange chips, air-side heat exchange fins, etc. Due to the dimensional tolerance of the parts themselves, the height of the core 200 is not unique.

[0055] (2) During the brazing process, the composite layer on the heat exchanger chip melts and disappears due to heat, which will cause the core 200 to shrink in size before and after welding.

[0056] (3) The main board 100 is an integrally formed structure, and the size of the main board 100 is fixed, which makes it difficult to adapt to the cores 200 of various sizes caused by dimensional tolerances. In addition, the main board 100 cannot change with the size of the core 200 during the brazing process.

[0057] When the main board 100 of the intercooler provided in the embodiment of the present application is assembled with the core 200, the first main body 120 and the second main body 110 are respectively placed on the upper and lower sides of the core 200, and the first end 121 and the second end 111 are overlapped to form a through channel 130 between the first main body 120 and the second main body 110, and the first main body 120 and the second main body 110, or the first end 121 and the second end 111, can move relative to each other at least in a direction perpendicular to the through channel 130, and the core 200 is located in the through channel and is close to the first main body 120 and the second main body 1 10. Since the first end 121 and the second end 111 are overlapped, the relative position between the first end 121 and the second end 111 can be adjusted within a certain range to adapt to the core 200 of different heights caused by dimensional tolerance. Moreover, during the brazing process, as the size of the core 200 changes, the relative position between the first end 121 and the second end 111 can also be changed accordingly within a certain range, so that the first main body 120 and the second main body 110 can better fit with the outer shell of the core 200, reducing the possibility of a gap between the outer shell of the core 200 and the main board 100.

[0058] Optionally, the first main body 120 has two first ends 121, the second main body 110 has two second ends 111, the two first ends 121 are connected to the two second ends 111 in a one-to-one correspondence, and the two first ends 121 are used to be arranged on opposite sides of the core 200. This allows the movement between the first main body 120 and the second main body 110 to be properly guided by the cooperation between the two first ends 121 and the two second ends 111 during the brazing process, so that the positional relationship between the relevant components of the intercooler is relatively accurate after the brazing is completed, thereby improving the quality of the product.

[0059] Optionally, the first end 121 has a first sealing surface 121b for facing the chamber body, a positioning groove 121c is formed on the first sealing surface 121b, and the first end 121 cooperates with the second end 111 through the positioning groove 121c to achieve the overlap of the first end 121 and the second end 111. Through the groove structure cooperation between the second end 111 and the positioning groove 121c, the relative movement range between the first end 121 and the second end 111 is limited to a certain extent during the brazing process, so that the intercooler has a higher assembly accuracy.

[0060] Optionally, the positioning groove 121c is a U-shaped groove, and the second end 111 has a protruding section 111c that cooperates with the U-shaped groove, and the cross section of the protruding section 111c is U-shaped. Through the cooperation between the U-shaped groove and the U-shaped section, the relative position and relative movement range of the first end 121 and the second end 111 can be limited from multiple directions, further improving the assembly accuracy of the intercooler.

[0061] Optionally, the second end 111 has a second sealing surface 111a for facing the chamber body, and the first sealing surface 121b and the second sealing surface 111a are located in the same plane. After the first main body 120 is connected to the second main body 110, it is necessary to seal and connect with the chamber body through the first sealing surface 121b and the second sealing surface 111a. The ports of the current chamber body used to cooperate with the main board 100 are mostly relatively regular rectangular shapes, and irregular structures such as step structures are usually not formed on the ports. Therefore, making the first sealing surface 121b and the second sealing surface 111a located in the same plane is conducive to the sealing cooperation between the two sealing surfaces and the port of the chamber body. Of course, when the port of the chamber body is designed in an irregular shape, in order to ensure the sealing effect, the first sealing surface 121b and the second sealing surface 111a may not be located in the same plane. The first sealing surface 121b and the second sealing surface 111a are located on the same plane. It can be understood that the first sealing surface 121b and the second sealing surface 111a may be located in the same plane or in the same curved surface. The first sealing surface 121b and the second sealing surface 111a may be designed with corresponding structures according to the needs of the intercooler.

[0062] Optionally, the positioning groove 121c has a positioning wall 121ca disposed facing the second main body 110, a sealing protrusion 121a is formed on the positioning wall 121ca, and a receiving groove 111b matched with the sealing protrusion 121a is formed on the end surface of the second end 111. During the brazing process, the first end 121 and the second end 111 may move relative to each other, which may cause a large gap between the positioning wall 121ca and the end surface of the second end 111, resulting in the gap being unable to be filled by the brazing agent. After the brazing is completed, a brazing hole is generated between the positioning wall 121ca and the end surface of the second end 111, causing the problem of compressed air leaking at the brazing hole. By setting up a structure in which the sealing protrusion 121a and the receiving groove 111b cooperate, on the one hand, the sealing protrusion 121a can effectively block the pressurized air entering the brazing pore, and reduce the leakage of the pressurized air when leakage occurs; on the other hand, when the first end 121 and the second end 111 produce relative movement perpendicular to the through channel 130, the size of the gap between the positioning wall 121ca and the end face of the second end 111 may change greatly, while the size of the gap between the sealing protrusion 121a and the walls of the receiving groove 111b on both sides thereof is almost unchanged or changes very little, which enables the flux to fill the gap well, thereby enabling at least the position where the sealing protrusion 121a and the receiving groove 111b are provided to obtain a good welding and sealing effect. In the embodiment of the present application, in order to achieve a good welding and sealing effect, the size of the gap between the sealing protrusion 121a and the walls of the receiving groove 111b on both sides thereof is controlled to be less than 0.1 mm.

[0063] Optionally, the sealing protrusion 121a is a triangular protrusion, so that one side of the triangle is formed on the positioning wall, the shape of the receiving groove 111b corresponds to the shape of the sealing protrusion 121a, and the size of the receiving groove 111b corresponds to the size of the sealing protrusion 121a. Of course, it is also possible to design the sealing protrusion 121a into a rectangle and design the receiving groove 111b accordingly. However, in this case, since the shape and size of the sealing protrusion 121a and the receiving groove 111b are consistent, when the first end 121 and the second end 111 move relative to each other, a large friction force may be generated between the sealing protrusion 121a and the receiving groove 111b, which will hinder the movement and have an adverse effect on the adaptation of the mainboard 100 to the deformation of the core 200. In addition, when connecting the first end 121 and the second end 111 , and it is not easy for the sealing protrusion 121a to extend into the receiving groove 111b; and the sealing protrusion 121a is a triangular protrusion, and the receiving groove 111b is designed accordingly, so that at least one side of the triangular protrusion is inclined relative to the direction in which the first end 121 moves relative to the second end 111, and thus almost no friction is generated between the side and the inner wall of the receiving groove 111b, thereby reducing the obstacle to the relative movement of the first end 121 and the second end 111 caused by the cooperation between the sealing protrusion 121a and the receiving groove 111b. When the second end 111 has the above-mentioned protruding section 111c, the receiving groove 111b can be formed in the protruding section 111c.

[0064] Optionally, the main board 100 includes a plurality of buckles 140 for fixing the chamber body, and the position where the first end 121 and the second end 111 cooperate is located between two adjacent buckles 140. In this way, the position where the main board 100 is disconnected to form the first main body 120 and the second main body 110 will not be located at the position of the buckle 140, thereby reducing the manufacturing difficulty of the main board 100 and avoiding the buckle 140 from affecting the buckling of the chamber body.

[0065] Another aspect of the present application provides an intercooler, including a chamber body and a core 200 , the intercooler also includes a main board 100 provided in an embodiment of the present application, the main board 100 is mounted on the core 200 , and the first end 121 is sealed and connected to the second end 111 .

[0066] The intercooler provided in the embodiment of the present application adopts the main board 100 of the intercooler provided in the embodiment of the present application. Since the first main body 120 and the second main body 110 are overlapped by the first end 121 and the second end 111, the relative positions of the first main body 120 and the second main body 110 can be adapted to the size of the core 200, and the positions of the first main body 120 and the second main body 110 can be adapted to the changes in the size of the core 200 during the brazing process, so that better sealing can be achieved between the main board 100 and the core 200, reducing the possibility of a gap between the outer shell of the core 200 and the main board 100.

[0067] Optionally, the intercooler provided in the embodiment of the present application further includes a sealing ring; the first main body 120 has a first sealing surface 121b arranged facing the chamber body, the second main body 110 has a second sealing surface 111a arranged facing the chamber body, the first sealing surface 121b and the second sealing surface 111a are located in the same plane, and the sealing ring is located between the chamber body, the first sealing surface 121b and the second sealing surface 111a, so as to realize static sealing by squeezing the sealing ring through the chamber body, the first sealing surface 121b and the second sealing surface 111a.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, 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 application.
