[0003] Currently, a commonly used evaporator end plate includes a left end plate and a right end plate. The right side edge of the left end plate is connected to the left side edge of the right end plate through connecting rib strips. Copper tube holes are arranged in both the left end plate and the right end plate. The included angle between two adjacent folds of the corresponding evaporator body of the left end plate and the right end plate is adjusted by bending the connecting rib strips. When bending the connecting rib strips, the bending is stopped when the lower half of the right side edge of the left end plate abuts against the lower half of the left side edge of the right end plate. Since there is no positioning and limiting structure between the left end plate and the right end plate, workers operate according to experience, and the left end plate and the right end plate are prone to dislocation (in the front-back direction) during the bending process, resulting in the need for multiple adjustments and affecting the assembly efficiency.

Specific embodiments
[0020] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] The orientations involved in the following text are based on Figure 1 the orientations of the various components in
[0022] As Figure 1 、 Figure 2 shown, the end plate of the evaporator of the present utility model includes a left end plate 1 and a right end plate 2. The right side edge of the left end plate 1 is connected to the left side edge of the right end plate 2 through a connecting rib 3. Copper - tube holes 12 are provided in both the left end plate 1 and the right end plate 2. A limiting convex plate 4 is provided on the front side wall of the left end plate 1, and a left - right direction limiting hole 6 is provided in the limiting convex plate 4. A limiting clamping plate 5 is provided on the left side edge of the right end plate 2. The limiting clamping plate 5 includes a vertical limiting part 51 and a protruding limiting part 52. The protruding limiting part 52 is connected and arranged on the front side of the vertical limiting part 51. When bending the connecting rib 3, the limiting clamping plate 5 can be inserted into the left - right direction limiting hole 6, and the front side wall of the limiting clamping plate 5 is in contact with the front inner wall of the left - right direction limiting hole 6, and the rear side wall of the limiting clamping plate 5 is in contact with the rear inner wall of the left - right direction limiting hole 6, or the rear side wall of the limiting clamping plate 5 is in contact with the front side wall of the left end plate 1. As Figure 3 、 Figure 4 shown, specifically, the front side wall of the protruding limiting part 52 is in contact with the front inner wall of the left - right direction limiting hole 6, the rear side wall of the vertical limiting part 51 is in contact with the rear inner wall of the left - right direction limiting hole 6, or the rear side wall of the vertical limiting part 51 is in contact with the front side wall of the left end plate 1.
[0023] When the left-right direction limit hole 6 is convenient for processing and forming, for example, the left end plate 1 and the limit convex plate 4 are made of plastic material, and the rear inner wall of the left-right direction limit hole 6 is also convenient to form. At this time, when the limit clamping plate 5 is inserted into the left-right direction limit hole 6, the rear side wall of the limit clamping plate 5 abuts against the rear inner wall of the left-right direction limit hole 6. When the left-right direction limit hole 6 is not convenient for processing and forming, for example, the left end plate 1 and the limit convex plate 4 are made of sheet metal, and the rear side of the left-right direction limit hole 6 needs to be set as a hollow structure during the processing and forming of the left-right direction limit hole 6. Again, Figure 1 、 Figure 3 as shown, at this time, when the limit clamping plate 5 is inserted into the left-right direction limit hole 6, the rear side wall of the limit clamping plate 5 abuts against the front side wall of the left end plate 1, and the limit clamping plate 5 is limited by the front side wall of the left end plate 1.
[0024] The front side wall of the limit clamping plate 5 abuts against the front inner wall of the left-right direction limit hole 6, and the rear side wall of the limit clamping plate 5 abuts against the rear inner wall of the left-right direction limit hole 6 means that the limit clamping plate 5 and the left-right direction limit hole 6 can move relatively in the left-right direction, but cannot move relatively in the front-rear direction. The front side wall of the limit clamping plate 5 abuts against the front inner wall of the left-right direction limit hole 6, and the rear side wall of the limit clamping plate 5 abuts against the front side wall of the left end plate 1 means that the limit clamping plate 5 and the left-right direction limit hole 6 as well as the limit clamping plate 5 and the left end plate 1 can move relatively in the left-right direction, but cannot move relatively in the front-rear direction.
[0025] When assembling the evaporator, first install the evaporator end plates on the evaporator body 13. Then, adjust the angle between two adjacent folds of the evaporator body 13 corresponding to the left end plate 1 and the right end plate 2 by bending the connecting rib 3. During the process of bending the connecting rib 3, the limit clamping plate 5 gradually snaps into the left-right direction limit hole 6. At the same time, the front side wall of the limit clamping plate 5 abuts against the front inner wall of the left-right direction limit hole 6, and the rear side wall of the limit clamping plate 5 abuts against the rear inner wall of the left-right direction limit hole 6. Or, the rear side wall of the limit clamping plate 5 abuts against the front side wall of the left end plate 1. When the lower half of the right side of the left end plate 1 abuts against the lower half of the left side of the right end plate 2, stop bending. During the bending process of the left end plate 1 and the right end plate 2, the limit clamping plate 5, the left-right direction limit hole 6, and the front side wall of the left end plate 1 play a role in positioning and limiting, effectively reducing the possibility of front-back direction misalignment of the left end plate 1 and the right end plate 2 during the bending process. The operation is simple and convenient, without the need for multiple adjustments, significantly improving the assembly efficiency of the evaporator. And, the limit clamping plate 5 includes a vertical limit portion 51 and a convex limit portion 52. The convex limit portion 52 is connected and arranged on the front side of the vertical limit portion 51. The structure of the limit clamping plate is simple and its own strength is high. The limit clamping plate 5 can be arranged in the left-right direction limit hole 6. The rear side of the convex limit portion 52 is a hollow structure, ensuring the connection strength between the two, ensuring the stability of the angle between two adjacent folds of the evaporator body 13, and improving the strength of the entire evaporator end plate.
[0026] Specifically, when bending the connecting rib 3, in order to facilitate snapping the limit clamping plate 5 into the left-right direction limit hole 6 and improve the positioning and limiting effect, as shown in Figure 1 、 Figure 2 again, a guiding beveled edge portion 53 is provided on the lower side edge of the vertical limit portion 51. The guiding beveled edge portion 53 is more likely to snap into the left-right direction limit hole 6, thereby guiding the entire limit clamping plate 5 to snap into the left-right direction limit hole 6.
[0027] In order to further improve the strength of the limit clamping plate 5 and improve its use effect, as shown in Figure 1 、 Figure 2 again, the right end plate 2 is provided with a reinforcing portion 14, and the limit clamping plate 5 is connected to the reinforcing portion 14.
[0028] In order to enable the evaporator end plate to be fixedly installed on the evaporator body 13, as shown in Figure 1 again, a mounting plate 7 is provided on the upper side edge of the right end plate 2. A connection hole is provided on the mounting plate 7, and a connection screw passes through the connection hole to detachably arrange the right end plate 2 on the evaporator body 13. In order to improve the strength of the mounting plate 7, the mounting plate 7 is provided with a reinforcing boss 8.
[0029] In order to facilitate the arrangement of the electric heating wire, as shown in Figure 1As shown, a wire routing slot 9 is provided on the lower side edge of the right end plate 2, and the electric heating wire is snap-fitted in the wire routing slot 9. A flanging structure is provided at the wire routing slot 9. The flanging structure prevents the wire routing slot 9 from cutting off the electric heating wire, and the flanging structure can also reinforce the strength of the wire routing slot 9.
[0030] When assembling the evaporator, it is necessary to connect the motor cover to the evaporator end plate. To achieve the connection between the motor cover and the evaporator end plate, as shown again Figure 1 As shown, a connecting pin 10 is provided on the left side edge of the left end plate 1. The connecting pin 10 is inserted into the motor cover pin hole to form a fastening structure. To improve the strength of the connecting pin 10, a reinforcing rib 11 is provided beside the connecting pin 10.
