[0054] Example 1

[0055] like Figure 1 As shown, a car heater core water chamber assembly of this embodiment includes a main board 1 and a water chamber cover 2, wherein:

[0056] Reference Figure 3-4 The main board 1 is provided with a side plate groove 105 at the end close to the pipe opening, and a fixing buckle 106 is extended outward from the other end away from the pipe opening. The setting of the side plate groove 105 is convenient for fixing the upper side plate 5. The fixing can be completed by directly inserting the end of the upper side plate 5, and the setting of the fixing buckle 106 is convenient for fixing with the end of the lower side plate 6. Finally, welding can be performed to complete the assembly of the upper side plate 5 and the lower side plate 6.

[0057] The middle part of the main board 1 is processed with a plurality of flat tube grooves 104 at equal intervals along its length direction. The ends of the flat tubes 8 are inserted into the flat tube grooves 104 for fixing, and then the flat tubes 8 can be assembled by welding. A first rib 101 is provided between two adjacent flat tube grooves 104. The water chamber assembly of this embodiment has the following functions by providing the first rib 101:

[0058] (1) The first rib 101 is provided to prevent the fins 7 installed between the flat tubes 8 from being attached to the main board 1. When entering the furnace for welding, the fins are generally thin. When the temperature is too high, the fins are easily melted and easily adhere to the main board 1, thereby affecting the heat exchange effect.

[0059] (2) The first convex rib 101 can effectively improve the strength of the entire main board 1. The thickness of the main board 1 can be made thinner than that of the existing conventional water chamber main board without reducing the strength and rigidity of the main board 1, which significantly saves the manufacturing cost. In addition, the convex rib can also improve the flatness of the main board 1, prevent it from twisting and deforming, and help improve the welding effect and welding rate.

[0060] (3) By providing the first convex rib 101, the pressing force of the fins 7 at both ends can be significantly increased, further reducing the risk of the fins 7 falling off;

[0061] (4) The first rib 101 is provided to increase the volume of the water chamber to a certain extent, thereby improving the heat dissipation transfer effect.

[0062] At the same time, if Figure 5-6 As shown, the middle part of the water chamber cover plate 2 of this embodiment is processed with a second rib 201 along its length direction. By setting the second rib 201, the water chamber cover plate 2 can also be made thinner without affecting its strength and service life. Specifically, the thickness of the main board 1 is 0.8-1.0 mm, and the thickness in this embodiment is specifically 0.8 mm, and the main board 1 is made of 10% 7072 / 3003 / 10% 4343 material. The thickness of the water chamber cover plate 2 is 1-1.2 mm, and the thickness in this embodiment is specifically 1.0 mm, and the water chamber cover plate 2 is made of 10% 7072 / 3003 / 10% 4343 material. It not only meets the needs of the development of lightweight automobiles and saves manufacturing costs, but also ensures the flatness of the water chamber cover plate 2, prevents its deformation, and improves its welding effect and welding rate with the main board 1. In addition, the setting of the second rib 201 can also increase the volume of the water chamber component to a certain extent and improve the heat dissipation effect.

[0063] When welding, the water chamber cover plate 2 and the two sides of the main board 1 are first connected by fastening parts. Specifically, Figure 1 and Figure 3-6 As shown, the fastening parts include buckle teeth 103 and buckle grooves 202. Multiple grooves 102 are processed at equal intervals on both sides of the main board 1 along its length direction. Buckle teeth 103 are arranged in the middle of the grooves 102. Buckle grooves 202 matching buckle teeth 103 are processed at the positions of the buckle teeth 103 on the water chamber cover plate 2 corresponding to the buckle teeth 103 on the main board 1. During assembly, the buckle teeth 103 correspond to the buckle grooves 202, and then the buckle teeth 103 are pressed into the buckle grooves 202 to complete the fixation, and then the main board 1 and the water chamber cover plate 2 are welded in a furnace to complete the convenient sealing assembly.

[0064] Example 2

[0065] like Figure 1-2 As shown, the structure of the water chamber assembly of this embodiment is basically the same as that of the embodiment 1, and the difference between the embodiment 1 and the embodiment 1 is that the end of the pipe opening of the main plate 1 is processed into a first straight section 107, a first arc section 108 and a first straight section 107 connected in sequence. The end of the pipe opening of the water chamber cover plate 2 is processed into a second straight section 203, a second arc section 204 and a second straight section 203 connected in sequence.

[0066] The traditional water chamber assembly includes a common main board 3 and a common water chamber cover plate 4, the nozzle of the common main board 3 is processed as a third arc segment 301, and the nozzle of the common water chamber cover plate 4 is processed as a third straight segment 401, a fourth arc segment 402 and a third straight segment 401 connected in sequence. When welding, the common water chamber assembly is a plane and a curved surface fit. The water chamber assembly of this embodiment is a plane and a plane fit, and in the welding process, the welding strength is better than the line-surface fit in the face-to-face fit, and in the actual production process, the plane and the curved surface fit has a higher tooling precision, and with the accumulated use and wear, if the tooling equipment is not maintained on time, it will cause uneven force on the curved surface and the plane, resulting in the formation of a line-surface fit on the mating surface, and the precision is reduced, which will cause the risk of leakage during furnace welding. Therefore, the utility model can reduce the difficulty of assembly by optimizing the nozzle structure of the main board 1 and the water chamber cover plate 2, and effectively solve the disadvantages of line-surface welding.

[0067] Example 3

[0068] This embodiment also provides a car heater core assembly, including a side plate assembly, a liquid inlet pipe 9 and a liquid outlet pipe 10, and also includes the water chamber assembly in embodiment 2, specifically, as Figure 7 As shown, in this embodiment, two groups of water chamber components of the new structure of the utility model are set, and the two groups of water chamber components are symmetrically arranged on both sides of the heater core assembly, and the side plate assembly is installed between the two groups of water chamber components, and the pipe mouth position of one group of water chamber components is connected to the liquid inlet pipe 9, and the pipe mouth position of the other group of water chamber components is connected to the liquid outlet pipe 10. It also includes flat tubes 8 and fins 7, and the flat tubes 8 are installed between the two groups of water chamber components, and the two ends of the flat tubes 8 are inserted into the flat tube grooves 104 of the main board 1 assembly. The fins 7 are arranged between any two adjacent flat tubes 8, and between the side plate assembly and the flat tube 8.

[0069] The water chamber component of the utility model is used to manufacture the heater core assembly, which can further improve the heat exchange effect and efficiency on the basis of ensuring the strength and rigidity of the entire core assembly, while also achieving the goal of lightweight manufacturing of the heater core and significantly reducing the manufacturing cost.

[0070] Example 4

[0071] like Figure 8-9 As shown, the automobile heater core assembly of this embodiment has a structure basically the same as that of embodiment 3, and the difference between it and embodiment 3 is that: the side panel assembly includes an upper side panel 5 and a lower side panel 6, and the upper side panel 5 has bosses 504 at both ends, and the bosses 504 are inserted into the side panel grooves 105 of the main board 1; the lower side panel 6 has notches 604 at both ends, and the notches 604 are buckled with the fixing buckles 106 of the main board 1.

[0072] The main board 1 of this embodiment is different from the ordinary main board 3 in design in that the original side panel assembly is inserted into the hole groove of the main board 1 and replaced with a side panel groove 105 structure, the size of which matches the bosses 504 set at both ends of the side panel assembly (mainly the upper side panel 5).

[0073] The lower end of the main board 1 is provided with a fixing buckle 106 and the two ends of the lower side plate 6 are provided with notches 604 rivet buckles. The advantages of this design are:

[0074] a) By eliminating the gaps between the original side plate and the original main plate, four matching gaps can be omitted in the single core process. Therefore, in the furnace welding process, the leakage point can be avoided compared with the original structure, thereby improving the one-time qualified rate.

[0075] b) It is replaced with a groove structure, which can not only cooperate with the bosses at both ends of the upper plate 5, but also cover the fins 7 so that they are not easy to fall off.

[0076] c) A protrusion is formed on the reverse side of the groove, which can serve as a reinforcing rib to enhance the stability of the main board 1 structure.

[0077] d) The fixing buckle 106 at the bottom can rivet the lower side plate 6, and the process operation is simple, which can make the lower side plate 5, the fin 7 and the main plate 1 firmly and stably connected, and the process operation is simple, thereby improving production efficiency and production quality.

[0078] Example 5

[0079] like Figure 8-9 As shown, the structure of the automobile heater core assembly of this embodiment is basically the same as that of embodiment 4, and the difference between this embodiment and embodiment 4 is that the thickness of the upper side plate 5 and the lower side plate 6 are both less than 0.8 mm, and the upper side plate 5 and the lower side plate 6 are respectively provided with reinforcing ribs along their length directions. Specifically, the upper side plate 5 is provided with symmetrically distributed first reinforcing ribs 501 along its length direction, and the first reinforcing ribs 501 are provided near the two side edges of the upper side plate 1. The lower side plate 6 is provided with symmetrically distributed second reinforcing ribs 601 along its length direction, and the second reinforcing ribs are provided near the two side edges of the lower side plate 1.

[0080] In the prior art, the thickness of conventional heating side panels is at least 1 mm. The upper and lower side panels provided in this embodiment can further reduce the thickness of the side panels by setting reinforcing ribs, and can be made thinner and lighter, meeting the needs of lightweight development of automobiles. The thickness of the material used for the upper side panel 5 and the lower side panel 6 of this embodiment is reduced by at least 20%, and the strength of the side panel can be significantly improved by setting two symmetrical reinforcing ribs, ensuring the horizontality of the side panel, being able to withstand greater stress, not easily deformed by distortion, and also meeting the quality standard of tensile strength of traditional thick side panels. After assembly, not only lightweight design is achieved, but also material costs are saved.

[0081] The upper side plate 5 is arranged above the fin 7 at the uppermost end of the core body, and is used to fix the fin 7 at the uppermost end of the core body assembly. The lower side plate 6 is arranged below the fin 7 at the lowermost end of the core body assembly, and is used to fix the fin 7 at the lowermost end of the core body assembly. By adopting the side plate assembly of the utility model, not only can the structural support stability of the entire warm air core assembly be increased, but also the protection of the fin 7 can be achieved, and the wear of the fin 7 during assembly or use can be avoided. Finally, the assembled core body assembly is put into the furnace for welding, the composite layer on the surface of the parts is melted at high temperature, and the flux flows into the fitting gap of the parts to achieve the welding effect. More optimally, during high-temperature welding, the core body will be deformed. Therefore, the reinforcing ribs provided on the side plate assembly of the utility model can increase its strength and avoid deformation of the core body.

[0082] Example 6

[0083] like Figure 8-9 As shown, the structure of the automobile heater core assembly of this embodiment is basically the same as that of embodiment 5, and the difference between this embodiment and embodiment 5 is that fin ribs are also arranged at equal intervals along the length direction of the upper side plate 5 and the lower side plate 6, and the fin ribs are arranged in the middle of the two reinforcing ribs. Specifically, the first fin ribs 503 are symmetrically arranged near the inner side of the two first reinforcing ribs 501, and the second fin ribs 603 are also symmetrically arranged near the inner side of the two second reinforcing ribs 601. There are multiple groups of fin ribs, which can be designed according to actual conditions. In this embodiment, three groups are specifically provided in the upper side plate 5 and the lower side plate 6. The three groups of fin ribs are evenly spaced and are respectively provided at the two ends and the middle part of the side plate. The provision of the fin ribs can further prevent the side plate (including the upper side plate 5 and the lower side plate 6) from deformation and improve the strength of the side plate. On the other hand, the provision of the fin ribs can play a role in fixing the fin 7, preventing the fin 7 from falling off and displacement, and ensuring that the fin 7 can be stably fixed in the middle part of the side plate after assembly. Compared with the traditional side plate, the fixing effect of the fin 7 is significantly improved. In addition, the difficulty of operation is reduced during the assembly of the fin 7, and the assembly efficiency is improved.

[0084] As a further improvement of this embodiment, Figure 1 and Figure 2 As shown, positioning holes (i.e., a first positioning hole 502 and a second positioning hole 602) are symmetrically processed at both ends of the center position of the upper side plate 5 or the lower side plate 6. The arrangement of the positioning holes facilitates the positioning of the side plate during the processing, transportation and assembly of the core assembly.

[0085] Compared with ordinary heater cores, the heater core assembly of the utility model has the advantages that each component has a simple structure, high rigidity and strong torsion resistance, so that the assembled core assembly has a stable structure and is easy to develop in a lightweight manner. In addition, by optimizing the structure of the water chamber component and the side plate component, it also has the characteristics of light weight, good stability, high heat exchange efficiency, large heating capacity, and more environmental protection.

[0086] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
