Abstract
Description
Technical Field
[0001] This application relates to the field of heat exchange technology, specifically to a heat exchanger for automobiles. Background Technology
[0002] To reduce the space occupied by heat exchangers during automotive installation, the manifolds of the front and rear rows of double-row or multi-row heat exchangers can be integrated into a single structure. However, due to differences in system temperature and application, the front and rear heat exchangers need to maintain a relative seal to prevent cross-flow of the heat exchange medium. In related technologies, during installation, the sealing rings between the front and rear rows of heat exchangers are prone to displacement or torsion due to compression between the components of the manifold, leading to reduced sealing performance. This can cause cross-flow of the heat exchange medium within the front and rear heat exchangers, affecting the product performance of the heat exchangers. Utility Model Content
[0003] This application provides a heat exchanger with better sealing performance between the front and rear rows.
[0004] The heat exchanger provided in this application includes a first manifold section, a second manifold section, and a plurality of heat exchange tubes. The first manifold section includes a first component, a second component, and a sealing component. The first component has a first protrusion on the side facing the second component, and the second component has a first groove on the side facing the first component. The sealing component includes a first sealing section, the length of which extends at least partially along the length of the first groove. The first component, the second component, and the sealing component are connected. In the connected state, the first sealing section is at least partially located within the first groove, the first protrusion abuts against the first sealing section, and the first sealing section deforms to seal the gap between the first protrusion and the first groove. A first cavity and a second cavity are provided between the first component and the second component, the first cavity and the second cavity being located on opposite sides of the first protrusion. The plurality of heat exchange tubes respectively connect the first cavity to the cavity of the second manifold section and the second cavity to the cavity of the second manifold section.
[0005] The first manifold section of the heat exchanger includes a first component, a second component, and a seal. The first component has a first protrusion, and the second component has a first groove. When the first component, the second component, and the seal are connected, the first sealing section of the seal is at least partially located in the first groove. When the first protrusion abuts against the first sealing section, the first groove can limit the first sealing section, reducing the possible displacement or torsion that may occur when the first sealing section is deformed under pressure, thereby improving the sealing performance of the first sealing section and helping to reduce the crossflow of heat exchange medium in the first and second chambers during heat exchanger operation.

[0018] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0019] It should be understood that the term "and / or" used in this application is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.
[0020] It should be noted that the directional terms such as "up," "down," "left," and "right" described in this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "up" or "down" to another element, it can be directly connected to the other element "up" or "down," or indirectly connected to the other element "up" or "down" through an intermediate element.
[0021] like Figure 1-10 As shown in the figure, this application provides a heat exchanger, which mainly includes a first manifold section 1, a second manifold section 2, and a plurality of heat exchange tubes 3. The first manifold section 1 and the second manifold section 2 are arranged at intervals relative to each other. The first manifold section 1 includes a first member 11, a second member 12, and a sealing member 13. The first member 11 has a first protrusion 111 on the side facing the second member 12, and the first protrusion 111 has an arc-shaped structure on the side facing the second member 12. The second member 12 has a first groove 121 on the side facing the first member 11, and the width of the first groove 121 is smaller than the width of the first protrusion 111. The sealing member 13 includes a first sealing section 131, and the length direction of the first sealing section 131 extends at least partially along the length direction of the first groove 121.
[0022] The first component 11, the second component 12, and the sealing component 13 are connected. In this connected state, the first sealing section 131 is at least partially located within the first groove 121, and the first protrusion 111 abuts against the first sealing section 131, thereby compressing the first sealing section 131. The first sealing section 131 deforms under compression and relatively seals the gap between the first protrusion 111 and the first groove 121. The first component 11 and the second component 12 have a first cavity 14 and a second cavity 15, which are located on opposite sides of the first protrusion 111. After the first sealing section 131 forms a seal, the first cavity 14 and the second cavity 15 are relatively sealed. Multiple heat exchange tubes 3 are respectively connected to the first cavity 14 and the cavity of the second manifold 2, and to the second cavity 15 and the cavity of the second manifold 2.
[0023] like Figure 1-2 As shown, in this embodiment, the second manifold section 2 is arranged at a distance from the first manifold section 1. The second manifold section 2 can have the same structure as the first manifold section 1 or different structures. Generally, their structures can be the same, that is, the second manifold section 2 is also divided into two mutually separated cavities, which are then connected to the first cavity 14 and the second cavity 15 of the first manifold section 1 through heat exchange pipes 3, respectively. Therefore, the specific structure of the second manifold section 2 will not be described in detail here. In addition, the heat exchanger in this embodiment is mainly used in automobile water tanks, and the heat exchange medium flowing inside is water. Therefore, the first manifold section 1 and the second manifold section 2 can be made of plastic materials, which can effectively reduce manufacturing costs. Multiple reinforcing ribs or reinforcing bars are integrally provided on the outer walls of the first manifold section 1 and the second manifold section 2. Of course, in some other embodiments, the first manifold section 1 and the second manifold section 2 can also be made of other metal materials such as aluminum alloy or stainless steel, which is not specifically limited here.
[0024] In this embodiment, the first manifold section 1 of the heat exchanger includes a first component 11, a second component 12, and a sealing component 13. The first component 11 is provided with a first protrusion 111, and the second component 12 is provided with a first groove 121. When the first component 11, the second component 12, and the sealing component 13 are connected, the first sealing section 131 of the sealing component 13 is at least partially located in the first groove 121. When the first protrusion 111 abuts against the first sealing section 131, the first groove 121 can limit the first sealing section 131, reducing the possible displacement or torsion that may occur when the first sealing section 131 is deformed under pressure, thereby improving the sealing performance of the first sealing section 131 and helping to reduce the phenomenon of crossflow of heat exchange medium in the first cavity 14 and the second cavity 15 during the operation of the heat exchanger.
[0025] like Figure 9-10 As shown, in one specific embodiment, the wall surface of the first groove 121 is provided with a second protrusion 122. The length direction of the second protrusion 122 extends at least partially along the length direction of the first groove 121. The protrusion height of the second protrusion 122 is defined as h, and the depth of the first groove 121 is defined as H, then h ≤ 1 / 2H. It should be noted that the length direction of the second protrusion 122 extending at least partially along the length direction of the first groove 121 means that the length direction of the second protrusion 122 can be completely along the length direction of the first groove 121, or it can only extend partially along the length direction of the first groove 121. For example, the second protrusion 122 may be wavy or have a bent section. Generally, the extension direction of the second protrusion 122 is the same as the extension direction of the first sealing section 131. Unless there are special requirements, both are straight in shape, which can reduce production costs and simplify processing and assembly.
[0026] As can be seen from the previous embodiment, the first groove 121 can limit the first sealing segment 131. When the first protrusion 111 abuts against and squeezes the first sealing segment 131, it can reduce the possible displacement or torsion that may occur when the first sealing segment 131 deforms under pressure. Furthermore, in this embodiment, the second protrusion 122 provided in the first groove 121 can simultaneously squeeze the first sealing segment 131 on the opposite side of the first protrusion 111 when the first protrusion 111 squeezes the first sealing segment 131. This causes the first sealing segment 131 to deform more at the position of the second protrusion 122, resulting in more deformation of the first sealing segment 131 to both sides. The contact area between the first sealing segment 131 and the sidewalls of both is larger and the contact is tighter, thereby improving the overall sealing effect.
[0027] It is understandable that when the protrusion height h of the second protrusion 122 is too high, it may affect the installation of the first sealing section 131, causing the first sealing section 131 to not fit well in the first groove 121, resulting in poor limiting of the first sealing section 131, or insufficient deformation of the first sealing section 131 after being squeezed, resulting in a gap between it and the second protrusion 122, affecting the seal. Therefore, the protrusion height h of the second protrusion 122 is often less than or equal to half the depth H of the first groove 121.
[0028] like Figure 9-10 As shown, in one specific embodiment, the number of second protrusions 122 is at least two, and the at least two second protrusions 122 are arranged at intervals along the width direction of the first groove 121. In the connected state, the first sealing section 131 can cover the gap between the second protrusions 122, and the projection of the first protrusion 111 in the first groove 121 is located between two adjacent second protrusions 122. In this embodiment, the projection of the first protrusion 111 in the first groove 121 is located between two adjacent second protrusions 122, that is, the first protrusion 111 is directly opposite the gap between two adjacent second protrusions 122. This connection structure allows for a larger contact area of at least two second protrusions 122, the first protrusion 111, and the first sealing section 131, forming a labyrinthine combined sealing structure, which can greatly improve the sealing reliability. Generally, two second protrusions 122 are sufficient to meet the sealing requirements; therefore, the number of second protrusions 122 is preferably two.
[0029] like Figure 9As shown, in one specific embodiment, the second protrusion 122 includes a first side 123 and a second side 124 that are connected to each other. The first side 123 and the second side 124 are respectively inclined to the depth direction of the first groove 121, and an arc transition angle is provided at the connection between the first side 123 and the second side 124. In the connected state, a part of the first sealing section 131 is located on one side of the first side 123 and a part is located on one side of the second side 124.
[0030] Specifically, in this embodiment, the cross-sectional shape of the second protrusion 122 is approximately a triangular structure with a rounded transition angle at the top. This structural shape minimizes the contact area between the second protrusion 122 and the first sealing section 131 on the top side, while increasing the contact area towards the bottom. This increases the pressure exerted by the second protrusion 122 on the first sealing section 131 on the top side while ensuring the contact area. This causes the first sealing section 131 to deform more towards the first side 123 and the second side 124. At the same time, this structure also allows the first sealing section 131 to fit more tightly with the first side 123 and the second side 124 of the second protrusion 122, reducing any gaps that may exist between them and thus ensuring sealing.
[0031] It should be noted that the angle between the first side 123 and the second side 124 and the depth direction of the first groove 121 can be determined according to factors such as the width and depth of the first groove 121. Therefore, this article does not make specific limitations. Generally speaking, as long as the inclination of the first side 123 and the second side 124 is not too large, a gentle angle can help with sealing.
[0032] like Figure 2 and Figure 4-5 As shown, in one specific embodiment, the first sealing section 131 includes a first wall surface 132 and a second wall surface 133 extending along the length direction. The first wall surface 132 is located on the side of the first sealing section 131 facing the first protrusion 111, and the second wall surface 133 is located on the side of the first sealing section 131 facing the first groove 121. The width of the first wall surface 132 is greater than the width of the second wall surface 133, and the first wall surface 132 has an arc groove 134 recessed towards the second wall surface 133. Specifically, the arc groove 134 may be located in the middle position of the first wall surface 132. In the connected state, the first protrusion 111 contacts the wall surface of the arc groove 134 and abuts against the first sealing section 131.
[0033] like Figure 5As shown, the first wall surface 132 faces the first protrusion 111, and the second wall surface 133 faces the first groove 121. In the connected state, the second wall surface 133 is located within the first groove 121. Since the width of the first wall surface 132 is greater than the width of the second wall surface 133, and the first wall surface 132 has an arc groove 134 recessed towards the second wall surface 133, the first protrusion 111 can fit into the position of the arc groove 134. During compression, the position of the arc groove 134 can be directly subjected to the compressive force of the first protrusion 111 and deform to both sides. At this time, due to the limiting of the first groove 121 and the structural setting that the width of the first wall surface 132 is greater than the width of the second wall surface 133, the first sealing section 131 can have more deformation towards the first protrusion 111 when it deforms, increasing the contact area between the first sealing section 131 and the first protrusion 111, thereby improving the sealing effect.
[0034] like Figure 2 and Figure 5 As shown, in one specific embodiment, the first sealing segment 131 further includes an arcuate wall surface 135, which is located on both sides of the first wall surface 132. The arcuate wall surface 135 connects the first wall surface 132 and the second wall surface 133, and is recessed within the first wall surface 132. After the first sealing segment 131 is located in the first groove 121, the arcuate wall surfaces 135 on both sides of the first sealing segment 131 can better fit against the walls on both sides of the first groove 121. After the first protrusion 111 squeezes the first sealing segment 131, the first sealing segment 131 deforms to both sides, squeezing the arcuate wall surface 135, thereby making the arcuate wall surface 135 in close contact with the walls on both sides of the first groove 121. The contact area between the entire first sealing segment 131 and the wall of the first groove 121 is larger, thereby improving the sealing performance.
[0035] like Figure 6-7 As shown, in one specific embodiment, the first sealing segment 131 includes a third wall surface 136 extending along the length direction. The third wall surface 136 is located on the side of the first sealing segment 131 facing the first groove 121. The third wall surface 136 has a second groove 137 extending a predetermined length along the length direction of the third wall surface 136. In the connected state, the second groove 137 abuts against the second protrusion 122.
[0036] In this embodiment, the cross-section of the first sealing section 131 is generally elliptical. The second groove 137 provided on the third wall surface 136 can cooperate with the second protrusion 122. The second protrusion 122 can provide a better limiting effect on the first sealing section 131 based on the first groove 121, further preventing the first sealing section 131 from shifting or flipping when it is squeezed during installation, thereby ensuring the sealing performance.
[0037] like Figure 4-7 As shown, in one specific embodiment, the sealing element 13 further includes a second sealing section 138 and a third sealing section 139, which are respectively spaced apart on both sides of the first sealing section 131. Generally, the first sealing section 131, the second sealing section 138, and the third sealing section 139 are an integral structure, and their two ends are integrally connected by a transverse sealing section. In the connected state, the end faces on both sides of the first element 11 respectively press the second sealing section 138 and the third sealing section 139, causing the second sealing section 138 and the third sealing section 139 to deform and seal both sides of the first element 11 and the second element 12 respectively. The cross-sectional shape of the second sealing section 138 and the third sealing section 139 can be circular or other shapes, which are not specifically limited herein. Figure 4-7 As shown, under the premise that the first sealing section 131 seals the gap between the first piece 11 and the second piece 12, the second sealing section 138 and the third sealing section 139 can seal the contact positions of the two on both sides respectively, thereby completing the relative sealing between the first cavity 14 and the second cavity 15.
[0038] like Figure 8-10 As shown, in one specific embodiment, the second piece 12 is further provided with a third groove 125 and a fourth groove 126 on the side facing the first piece 11. The third groove 125 and the fourth groove 126 are respectively located on both sides of the first groove 121. In the connected state, the second sealing section 138 is at least partially located in the third groove 125, and the third sealing section 139 is at least partially located in the fourth groove 126.
[0039] In this embodiment, the third groove 125 and the fourth groove 126 can respectively limit the second sealing section 138 and the third sealing section 139 of the seal 13. With the first sealing section 131 also limited, the connection between the seal 13 and the second piece 12 can be more stable. When the first piece 11 and the second piece 12 are fastened together and squeeze the seal 13, the seal 13 can be better kept in its original position, thereby ensuring the overall sealing performance.
[0040] like Figure 1-3As shown, in one specific embodiment, the first component 11 includes an integrally formed first wall portion 112 and a second wall portion 113, with a first gap 114 between the first wall portion 112 and the second wall portion 113. The first wall portion 112 includes a first connecting pipe 115, which communicates with the first cavity 14. The second wall portion 113 includes a second connecting pipe 116, which communicates with the second cavity 15. Generally, both the first wall portion 112 and the second wall portion 113 are U-shaped structures. After being connected to the second component, the cavities of the U-shaped structures respectively form the first cavity 14 and the second cavity 15. The gap between the first wall portion 112 and the second wall portion 113 can reduce heat transfer between them. Furthermore, the sizes of the first wall portion 112 and the second wall portion 113 can be the same or different, which will not be elaborated upon here.
[0041] The above examples illustrate the principles and implementation methods of this application. The descriptions of the embodiments are merely for the purpose of helping to understand the methods and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications should also fall within the protection scope of this application.
