Evaporators usually consist of several folds, each with fins and copper tubes. The side plates are used to secure the evaporator folds to maintain the required angle between adjacent folds.

[0003] After the side plate is installed on the evaporator, it can be bent together with the evaporator. However, when the bending angle is large, the two adjacent plates are prone to misalignment during the bending process, which requires multiple adjustments or additional fasteners to remedy the situation, affecting assembly efficiency. Utility Model Content

[0006] The first side plate includes a first plate body, a second plate body, and a first connecting rib connecting the first plate body and the second plate body. The first side plate has a bent state by bending the first connecting rib.

[0007] The first side plate also includes a connecting flange, which includes a first flange portion that is stacked with the first plate body and a second flange portion that protrudes from the first flange portion toward the second plate body. In the bent state, the second flange portion can be connected to the second plate body.

[0008] In one embodiment, in the unbent state, the second flange portion overlaps with the second plate body portion.

[0009] In one embodiment, the second plate has a protrusion that protrudes toward the first plate, and the second flange is connected to the protrusion in the bent state.

[0013] The limiting structure is configured as a protrusion on the first plate, and the protrusion can be adapted to abut against the first arc surface.

[0014] In one embodiment, the connecting flange has a first mounting hole, and the protrusion has a second mounting hole that mates with the first mounting hole.

[0015] In one embodiment, the limiting structure is concentrically arranged with the second assembly hole.

[0016] In one embodiment, the first side plate further includes a third plate body and a second connecting rib, wherein the third plate body is connected to the second plate body via the second connecting rib;

[0043] Existing heat exchangers, especially evaporators, are typically fixed to the air conditioner base via side plates. Evaporators usually consist of several folds, each with fins and copper tubes. The side plates are used to secure the evaporator folds to maintain the required angle between adjacent folds.

[0044] After the side plate is installed on the evaporator, it can be bent together with the evaporator. However, when the bending angle is large, the two adjacent plates are prone to misalignment during the bending process, which requires multiple adjustments or the addition of fasteners to remedy the situation. Alternatively, the side plate can be disassembled into multiple independent parts, which affects the assembly efficiency.

[0045] To solve this technical problem, this utility model proposes a heat exchanger side plate.

[0046] Please see Figures 1 to 3 , Figure 5 In one embodiment of this utility model, the heat exchanger side plate includes a first side plate 10; the first side plate 10 includes a first plate body 11, a second plate body 13, and a first connecting rib 12 connecting the first plate body 11 and the second plate body 13. The first side plate 10 has a bent state by bending the first connecting rib 12; the first side plate 10 also includes a connecting flange 16, the connecting flange 16 including a first flange portion 161 stacked with the first plate body 11, and a second flange portion 162 protruding from the first flange portion 161 toward the direction close to the second plate body 13. In the bent state, the second flange portion 162 can be connected to the second plate body 13; thereby improving the overall assembly efficiency.

[0047] In the technical solution of this utility model, the heat exchanger side plate is installed on the end face of the heat exchanger 30. The first side plate 10 includes a first plate body 11, a first connecting rib 12, and a second plate body 13. The first plate body 11 and the second plate body 13 correspond to different folds of the heat exchanger 30, and are connected by the first connecting rib 12 to ensure the structural stability and reliability of the first side plate 10. The included angle between two adjacent folds of the heat exchanger 30 corresponding to the first plate body 11 and the second plate body 13 can be adjusted by bending the first connecting rib 12.

[0048] Furthermore, the first side plate 10 also includes a connecting flange 16, which includes a first flange portion 161 and a second flange portion 162. The first flange portion 161 is connected to the first plate body 11, and the first flange portion 161 and the first plate body 11 are stacked, so that the connecting flange 16 is parallel to the first plate body 11 as a whole. Then, when the first connecting rib 12 is bent so that the first plate body 11 and the second plate body 13 are close to each other, the second flange portion 162 protrudes from the first flange portion 161 towards the direction close to the second plate body 13. The second flange portion 162 can be located on the front side of the second plate body 13, which can reduce the possibility of interference between the connecting flange 16 and the second plate body 13, and can also effectively reduce the possibility of misalignment between the first plate body 11 and the second plate body 13 in the front and rear directions. At the same time, it facilitates the connection between the first plate body 11 and the second plate body 13, and the operation is simple and convenient, without the need for multiple adjustments, which helps to improve assembly efficiency and achieve a reliable connection between the connecting flange 16 and the second plate body 13.

[0049] It should be noted that the first side plate 10 is a one-piece molded sheet metal part, such as... Figure 11 and Figure 12 As shown, the first plate 11, the first connecting rib 12, and the second plate 13 are located on the same side end face of the heat exchanger 30. The heat exchanger side plate also includes a second side plate 20, which can be fixedly connected to the first side plate 10 by fasteners such as screws and rivets.

[0050] Specifically, the connecting flange 16 has an unfolded state and a folded state, such as Figure 8 and Figure 9 As shown, in the unfolded state, the connecting flange 16 is located on the same plane as the first plate 11, the second plate 13, etc., which facilitates the processing and manufacturing of the first side plate 10 and improves production efficiency; Figure 6 and Figure 7 As shown, the connecting flange 16 is folded upwards and is in a folded state. At this time, the connecting flange 16 is parallel to the first plate 11. The second flange 162 extends toward the second plate 13 and is located on the front side of the second plate 13. The two are not on the same plane. This can facilitate the connection between the first plate 11 and the second plate 13, reduce the possibility of interference between the connecting flange 16 and the second plate 13, and reduce the possibility of misalignment in the front and rear directions of the first plate 11 and the second plate 13 during the bending process. That is, the second plate 13 can only move behind the second flange 162, so as to achieve a fixed connection between the second plate 13 and the second flange 162.

[0051] In addition, such as Figure 5As shown, the first flange 161 is stacked and spaced apart from the first plate 11. When the second flange 162 is connected to the second plate 13, the first flange 161 can be forced against the first plate 11, which can increase the effective contact area between the first flange 161 and the first plate 11 to a certain extent, improve the structural stability and connection strength between the first plate 11 and the connecting flange 16, and also facilitate the improvement of the connection reliability between the first plate 11 and the second plate 13.

[0052] The first side plate 10 is provided with a copper tube mating hole 101 through which the copper tube 31 passes. When the connecting flange 16 in the folded state is too close to the copper tube mating hole 101 or the annular protrusion at the copper tube mating hole 101, such as... Figure 1 and Figure 8 As shown, the connecting flange 16 is provided with a relief groove 164 for avoiding the copper tube 31 of the heat exchanger 30, which reduces the possibility of interference between the connecting flange 16 and the copper tube 31 and ensures convenient assembly of the copper tube 31.

[0053] Please see Figure 6 and Figure 7 In this embodiment of the invention, in the unbent state, the second flange 162 partially overlaps with the second plate 13. It is understood that after folding the connecting flange 16 from its unfolded state to its folded state, the projection of the second flange 162 and the projection of the second plate 13 at least partially overlap in the front-back direction. This ensures that the second flange 162 and the second plate 13 are stacked in the front-back direction, and the second flange 162 can act as a limiting guide. Therefore, even if the bending angle of the first side plate 10 is too large, the second flange 162 will never collide with the second plate 13 during the bending process. The second plate 13 can only move behind the second flange, improving the bending reliability of the first side plate 10. Of course, in other embodiments, the second flange 162 does not overlap with the second plate 13; it is sufficient to ensure that the second flange 162 is arranged on the front side of the second plate 13.

[0054] Optionally, in an embodiment of the present invention, the second plate 13 is provided with a protrusion 17 protruding toward the first plate 11, and the second flange 162 is connected to the protrusion 17 in the bent state. In this way, by providing the protrusion 17 on the second plate 13, the position on the second plate 13 for opening the copper tube mating hole 101 is not occupied, and the overlapping arrangement between the second flange 162 and the second plate 13 and the connection after bending are convenient, which helps to improve the overall assembly efficiency.

[0055] Furthermore, in an embodiment of this utility model, the first plate 11 is provided with a limiting structure for abutting the protrusion 17. The setting of the limiting structure can constrain and limit the rotation stroke of the second plate 13, avoid excessive rotation of the second plate 13, or even cause the first connecting rib 12 to break, improve the bending reliability of the first side plate 10, and at the same time improve the connection reliability between the connecting flange 16 and the protrusion 17.

[0056] Please see Figure 3 and Figure 4 , Figure 9 and Figure 10 In an embodiment of this utility model, the outer edge surface of the protrusion 17 is a first arc surface 171; thus, damage to the first plate 11 can be reduced when the protrusion 17 approaches the first plate 11.

[0057] In one embodiment, the limiting structure is configured to form a second arc surface 111 on the first plate 11, and the first arc surface 171 is adapted to the second arc surface 111. It can be understood that when the first connecting rib 12 is bent, causing the second plate 13 to rotate closer to the first plate 11, since the first plate 11 and the second plate 13 are located on the same plane, the second arc surface 111 is formed on the side edge surface of the first plate 11 close to the second plate 13. Through the adapted arrangement of the first arc surface 171 and the second arc surface 111, the second arc surface 111 of the second plate 13 can fully abut against the first arc surface 171, thereby stopping the rotation and preventing the second plate 13 from rotating excessively and causing damage to the first side plate 10. This facilitates the fixed assembly of the first plate 11 and the second plate 13, improves the reliability of the first side plate 10, and extends the service life of the first side plate 10.

[0058] In another embodiment, the limiting structure is configured as a protrusion on the first plate 11, the protrusion being adaptable to abut against the first arc surface 171. This protrusion can be located on the first arc surface 171 of the first plate 11, similarly preventing excessive rotation of the second plate 13 from damaging the first side plate 10, and facilitating the fixed assembly of the first plate 11 and the second plate 13. Of course, in other embodiments, the protrusion can be located on the side of the folded connecting flange 16 facing the second plate 13.

[0059] Optionally, in an embodiment of this utility model, the connecting flange 16 is provided with a first mounting hole 163, and the protrusion 17 is provided with a second mounting hole 172 that cooperates with the first mounting hole 163. Then, by passing fasteners such as screws through the first mounting hole 163 and the second mounting hole 172, the first plate 11 and the second plate 13 can be fixed, thereby fixing the included angle between two adjacent folds of the heat exchanger 30 corresponding to the first plate 11 and the second plate 13.

[0060] Furthermore, in an embodiment of this utility model, the limiting structure is concentrically arranged with the second assembly hole 172. It can be understood that... Figure 1 and Figure 2 , Figure 10 As shown, when the limiting structure is configured as the second arc surface 111, and the second arc surface 111 is adapted to the first arc surface 171 of the protrusion 17, the center of the first mounting hole 163 is the same as the generatrix center of the second arc surface 111, and the center of the second mounting hole 172 is the same as the generatrix center of the first arc surface 171. Because the generatrix center of the second arc surface 111 and the generatrix center of the first arc surface 171 are concentrically set, when the first arc surface 171 and the second arc surface 111 abut against each other, the concentricity of the first mounting hole 163 and the second mounting hole 172 after bending can be guaranteed, thereby facilitating the insertion of fasteners and realizing the relative fixation between the first plate 11 and the second plate 13, which helps to improve the overall assembly efficiency.

[0061] When the limiting structure is configured as a protrusion formed on the first plate 11, the protrusion is located on the second arc surface 111 and is provided at intervals. At this time, the third arc surface formed by the free ends of the multiple protrusions is adapted to the first arc surface 171 of the protrusion 17. The center of the first mounting hole 163 is the same as the generatrix center of the third arc surface, and the center of the second mounting hole 172 is the same as the generatrix center of the first arc surface 171. Because the generatrix center of the third arc surface is concentric with the generatrix center of the first arc surface 171, when the first arc surface 171 and the third arc surface abut, the concentricity of the first mounting hole 163 and the second mounting hole 172 after bending can be guaranteed, thereby facilitating the insertion of fasteners and realizing the relative fixation between the first plate 11 and the second plate 13, which helps to improve the overall assembly efficiency.

[0062] Please see Figure 1 and Figure 8 In an embodiment of this utility model, the first side plate 10 further includes a third plate 15 and a second connecting rib 14. The third plate 15 is connected to the second plate 13 through the second connecting rib 14. Thus, the first plate 11, the second plate 13, and the third plate 15 correspond to different folds of the heat exchanger 30. In this way, the included angle between two adjacent folds of the first plate 11 and the second plate 13 can be adjusted by bending the first connecting rib 12, and the included angle between two adjacent folds of the second plate 13 and the third plate 15 can be adjusted by bending the second connecting rib 14.

[0063] Specifically, the second plate 13 is also provided with the connecting flange 16. In the bent state, the connecting flange 16 can be connected to the third plate 15. It can be understood that the second plate 13 is located between the first plate 11 and the third plate 15. In order to ensure the fixed connection between the second plate 13 and the first plate 11 and the second plate 13, the second plate 13 is provided with the connecting flange 16. The connecting flange 16 includes a first flange portion 161 that is stacked with the second plate 13 and a second flange portion 162 that protrudes from the first flange portion 161 toward the direction close to the third plate 15. Thus, in the bent state, the second flange portion 162 on the second plate 13 can be connected to the third plate 15.

[0064] Furthermore, the third plate 15 is provided with a protrusion 17 protruding towards the second plate 13, and the second plate 13 is provided with a limiting structure for abutting the protrusion 17. In this way, by using the limiting structure on the second plate 13 to abut the protrusion 17 on the third plate 15, the rotation of the third plate 15 can be constrained and limited, which helps to contribute to the concentric setting of the first mounting hole 163 connecting the flange 16 and the second mounting hole 172 of the protrusion 17, thereby facilitating the insertion of fasteners and realizing the relative fixation between the second plate 13 and the third plate 15, thus improving the overall assembly efficiency.
