Description

Technical Field

[0001] The utility model relates to the technical field of automobile air conditioners, in particular to an evaporator lower shell and an evaporator structure. Background Art

[0002] The car air conditioning system is an important part of modern vehicles. It not only regulates the temperature inside the car, but also improves the air quality and provides passengers with a more comfortable and healthy riding environment.

[0003] In the automotive air-conditioning industry, the evaporator is one of the indispensable structures. The evaporator shell includes the evaporator upper shell and the evaporator lower shell. When assembling the automotive air-conditioning, the evaporator lower shell is docked with the distribution box. The evaporator lower shell is usually made of plastic material. By using a mold of a specific shape, the evaporator lower shell can be mass-produced through processes such as injection molding.

[0004] The evaporator lower shell includes two side panels and a bottom plate. The two side panels are respectively arranged at both ends of the bottom plate. When the mold is used to produce the evaporator lower shell, since the middle part of the bottom plate is a plate-like structure with low structural strength, during the corresponding mold processing and production process, the width of the position corresponding to the bottom plate on the mold is relatively large, and it is easy to deform during processing. It is necessary to increase the pre-deformation amount of a certain angle at the position corresponding to the bottom plate to avoid affecting the quality of the evaporator lower shell after the mold is deformed. However, the pre-deformation amount is difficult to control and requires repeated testing for adjustment, which not only increases the workload and labor costs, but also increases the difficulty of mold manufacturing. If the evaporator lower shell is deformed after production, it may cause installation difficulties, poor sealing, water seepage and air leakage, etc., thereby affecting the normal operation of the evaporator.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0030] See also Figure 1 The utility model provides an evaporator lower shell, including a bottom plate 1, two side plates 2 and a reinforcement part 3, the two side plates 2 are respectively arranged at both ends of the bottom plate 1, and the two side plates 2 and the bottom plate 1 are enclosed to form a drainage cavity (not shown in the figure); the reinforcement part 3 is arranged on the bottom plate 1, and the length direction of the reinforcement part 3 is parallel to the first direction X, that is, the reinforcement part 3 extends along the first direction X; the first direction X is parallel to the length direction of the bottom plate 1.

[0031] In this embodiment, the bottom plate 1 is an arc-shaped plate structure, one side of the bottom plate 1 extends downward, the two side plates 2 are integrally formed with the bottom plate 1, and a drain pipe 13 is connected to the bottom surface of the bottom plate 1 to discharge the liquid in the drainage cavity to the outside; the reinforcement part 3 is fixedly arranged on the bottom plate 1. It should be noted that the side of the bottom plate 1 facing the outside is also the side of the bottom plate 1 away from the drainage cavity.

[0032] In this way, by providing a reinforcing portion 3 extending along the first direction X, the structural strength of the bottom plate 1 can be improved, so that when it is subjected to pressure, the pressure can be transmitted to the two side plates 2 through the reinforcing portion 3, so that the mold corresponding to the lower shell of the evaporator is not easy to deform during the processing, saving the steps of designing the pre-deformation amount and adjusting the pre-deformation amount, reducing the difficulty of mold production, and the produced lower shell of the evaporator can be better connected with the distribution box and the evaporator structure during use, avoiding the occurrence of loose sealing, liquid leakage, air leakage and the like, thereby improving the product qualification rate.

[0033] It can be understood that the shape of the bottom plate 1 can be adjusted according to actual needs. In the present embodiment, the bottom plate 1 is an arc-shaped plate structure extending downward, so as to facilitate the liquid in the drainage cavity to be discharged to the outside through the drainage pipe 13 to avoid accumulation inside the drainage cavity; further, a water guiding structure can be provided in the drainage cavity to guide the liquid to flow into the drainage pipe 13, which will not be elaborated here.

[0034] See also Figure 1 and Figure 2 In some embodiments, a plurality of reinforcing parts 3 are provided, and the plurality of reinforcing parts 3 are arranged along the first direction X at intervals.

[0035] There are five reinforcing parts 3 , which are arranged at equal intervals along the first direction X, and the length direction of each reinforcing part 3 is parallel to the first direction X.

[0036] In this way, multiple reinforcing parts 3 arranged along the first direction X can further enhance the structural strength of the bottom plate 1, and transmit the force received by the bottom plate 1 along the first direction X, making it difficult for the bottom plate 1 to deform, improving the sealing performance and structural strength of the lower shell of the evaporator, enabling the lower shell of the evaporator to be stably connected to the distribution box, and improving the yield rate of the product; reducing the design and production difficulties of the mold for the lower shell of the evaporator, and facilitating the mass production of the lower shell of the evaporator.

[0037] It can be understood that the multiple reinforcing parts 3 can also be arranged at unequal intervals. The lengths of each reinforcing part 3 can be the same or different. The length, setting position, and quantity of the reinforcing parts 3 can all be adjusted according to actual needs, and will not be listed in detail here.

[0038] Refer to Figure 2 , in some embodiments, the reinforcing part 3 is arranged on the side of the bottom plate 1 facing away from the outside, that is, the side of the bottom plate 1 facing the evaporator structure.

[0039] In this way, the reinforcing part 3 is arranged on the side of the bottom plate 1 facing the evaporator structure, which can improve the structural strength of the bottom plate 1 without increasing the external volume of the lower shell of the evaporator, and transmit the force on the bottom plate 1 along the first direction X to the two side plates 2, so as to improve the structural strength of the lower shell of the evaporator, enable the lower shell of the evaporator to be stably connected to the distribution box, and reduce the processing difficulty of the mold for the lower shell of the evaporator.

[0040] It can be understood that the reinforcing part 3 can also be arranged on the side of the bottom plate 1 facing the outside, as long as it can achieve the improvement of the structural strength of the bottom plate 1, and will not be elaborated here.

[0041] Refer to Figure 2 , in some embodiments, the reinforcing part 3 is integrally formed with the bottom plate 1, and the reinforcing part 3 extends in the direction away from the outside and protrudes from the bottom plate 1.

[0042] In this embodiment, the depth of the reinforcing part 3 located at the center of the bottom plate 1 (that is, the distance protruding from the bottom plate 1) is greater than the depths of the other reinforcing parts 3. The reinforcing parts 3 are all formed into rectangular groove structures through a stamping process, and the connection between the reinforcing parts 3 and the bottom plate 1 is provided with a smooth transition.

[0043] In this way, the reinforcing part 3 is integrally formed with the bottom plate 1, which is convenient for processing the lower shell of the evaporator through a mold, and at the same time improves the connection strength between the reinforcing part 3 and the bottom plate 1, thereby improving the structural strength of the bottom plate 1, avoiding deformation of the lower shell of the evaporator and affecting the normal operation of the evaporator; the mold designed according to the lower shell of the evaporator can also maintain a high structural strength, making it not easy to deform during the process of processing and producing the lower shell of the evaporator, and improving the yield rate of the lower shell of the evaporator.

[0044] It is understandable that the reinforcing portion 3 may also extend in a direction toward the outside and protrude from the bottom plate 1 . The direction of the reinforcing portion 3 may be flexibly adjusted, which will not be listed in detail here.

[0045] See also Figures 2 - 4 In some embodiments, the reinforcing portion 3 is connected to a first reinforcing plate 31 and a second reinforcing plate 32, and the first reinforcing plate 31 and the second reinforcing plate 32 are respectively arranged on both sides of the reinforcing portion 3, that is, the first reinforcing plate 31 and the second reinforcing plate 32 are respectively arranged on the side of the reinforcing portion 3 facing the outside world and the side away from the outside world.

[0046] In this way, the first reinforcing plate 31 and the second reinforcing plate 32 can further strengthen the structural strength of the bottom plate 1, so that the bottom plate 1 is not easily deformed under the action of external force, and the lower shell of the evaporator can be stably connected to the distribution box and the evaporator structure, thereby improving the sealing performance of the lower shell of the evaporator; and, the mold set according to the lower shell of the evaporator also has sufficient structural strength, which saves the step of designing the pre-deformation amount of the mold and reduces the difficulty of mold design.

[0047] It is understandable that the first reinforcing plate 31 and the second reinforcing plate 32 may be connected only to the reinforcing portion 3, or may be partially connected to the reinforcing portion 3 and partially connected to the bottom plate 1 to improve the connection strength between the reinforcing portion 3 and the bottom plate 1, which will not be listed in detail here.

[0048] See also Figure 3 and Figure 4 In some embodiments, the first reinforcing plate 31 is disposed on the side of the reinforcing portion 3 facing the outside, and the second reinforcing plate 32 is disposed on the side of the reinforcing portion 3 facing away from the outside. Each reinforcing portion 3 is connected to a first reinforcing plate 31 and a second reinforcing plate 32.

[0049] In this way, the first reinforcing plate 31 and the second reinforcing plate 32 are arranged on both sides of the reinforcing portion 3, which can further increase the structural strength of the reinforcing portion 3, thereby increasing the structural strength of the bottom plate 1, making the bottom plate 1 less likely to deform and able to be stably assembled to the evaporator structure.

[0050] It can be understood that the first reinforcing plate 31 and the second reinforcing plate 32 can also be arranged on the same side of the reinforcing portion 3. In this embodiment, the first reinforcing plate 31 and the second reinforcing plate 32 are respectively arranged on both sides of the bottom plate 1. The purpose is to reasonably utilize the space on both sides of the reinforcing portion 3 so that the structural strength on both sides of the reinforcing portion 3 is improved, which is convenient for transmitting force to the two side plates 2 and avoiding deformation of the evaporator lower shell and the mold corresponding to the evaporator lower shell.

[0051] Further, only some of the plurality of reinforcing portions 3 may be provided with the first reinforcing plate 31 and the second reinforcing plate 32. Or, among the plurality of reinforcing portions 3, some are provided with the first reinforcing plate 31 and the other part is provided with the second reinforcing plate 32. Or, a plurality of first reinforcing plates 31 or a plurality of second reinforcing plates 32 are provided on one reinforcing portion 3. It is not limited to the one-to-one correspondence setting of the reinforcing portion 3, the first reinforcing plate 31, and the second reinforcing plate 32, and no more examples are listed here.

[0052] Refer to Figure 2 and Figure 3 , in some embodiments, the first reinforcing plate 31 extends along the first direction X, and the second reinforcing plate 32 is arranged at an angle to the first direction X. In this embodiment, the first reinforcing plate 31 is arranged in a groove formed by the reinforcing portion 3 extending in a direction away from the outside, and both ends of the first reinforcing plate 31 are fixedly connected to the reinforcing portion 3. The second reinforcing plate 32 is perpendicular to the side wall of the reinforcing portion 3 facing the drainage cavity.

[0053] In this way, the first reinforcing plate 31 arranged on the side of the reinforcing portion 3 facing the outside can improve the structural strength of the reinforcing portion 3 in the first direction X, facilitating the transfer of the forces received by the reinforcing portion 3 and the bottom plate 1 to the two side plates 2, making the force on the evaporator lower housing more uniform. The second reinforcing plate 32 is perpendicular to the reinforcing portion 3, which can prevent the liquid in the drainage cavity from accumulating at the connection between the second reinforcing plate 32 and the reinforcing portion 3, facilitating the drainage of the liquid in the drainage cavity to the outside through the drain pipe 13 and improving the drainage efficiency of the evaporator lower housing.

[0054] It can be understood that the extension direction of the first reinforcing plate 31 and the extension direction of the second reinforcing plate 32 can both be adjusted according to actual needs, and the shapes of the first reinforcing plate 31 and the second reinforcing plate 32 can also be the same, as long as it can achieve the improvement of the structural strength of the reinforcing portion 3.

[0055] Refer to Figure 3 , in some embodiments, the evaporator lower housing further includes reinforcing ribs 4, and the reinforcing ribs 4 are arranged on the bottom plate 1 and the side plates 2. Among them, there are a plurality of reinforcing ribs 4. The length direction of the reinforcing ribs 4 arranged on the bottom plate 1 is perpendicular to the first direction X, and the plurality of reinforcing ribs 4 arranged on the bottom plate 1 are evenly spaced on the side of the bottom plate 1 facing the outside. The length direction of the reinforcing ribs 4 arranged on the side plates 2 is perpendicular to the first direction X, and the plurality of reinforcing ribs 4 arranged on the side plates 2 are evenly spaced on the side walls of the two side plates 2 facing away from each other.

[0056] In this way, the reinforcing ribs 4 can further enhance the structural strength of the bottom plate 1, and the reinforcing portion 3 and the reinforcing ribs 4 can transfer the forces received by the evaporator lower housing along their extension directions, avoiding the deformation of the evaporator lower housing and the corresponding mold, facilitating the assembly of the evaporator lower housing, improving the sealing performance of the evaporator lower housing, and reducing the processing difficulty of the mold.

[0057] It can be understood that the number and the setting position of the reinforcing ribs 4 can be adjusted flexibly. The length direction of the reinforcing ribs 4 can also be parallel to the first direction X. There is no need to list them in detail here. In this embodiment, the length direction of the reinforcing ribs 4 arranged on the bottom plate 1 is perpendicular to the first direction X, so as to enhance the structural strength of the bottom plate 1 in other directions.

[0058] Refer to Figure 3 and Figure 4 , in some embodiments, the bottom plate 1 includes a first part 11 and a second part 12. The first part 11 is connected to the second part 12. The second part 12 is located below the first part 11. The reinforcing part 3 is arranged on the first part 11. The evaporator lower shell further includes reinforcing ribs 4, and the reinforcing ribs 4 are arranged on the second part 12. In this embodiment, the first part 11 is arranged vertically, the middle part of the bottom surface of the second part 12 extends downward, and the drain pipe 13 is fixedly connected to the second part 12 and communicated with the lowest part of the second part 12.

[0059] In this way, the second part 12 is inclined downward, so that the liquid in the drainage cavity can flow into the drain pipe 13 under the action of its own gravity, avoiding the liquid remaining in the drainage cavity; arranging the reinforcing part 3 on the first part 11 and the reinforcing ribs 4 on the second part 12 can respectively improve the structural strength of the first part 11 and the second part 12, and further improve the overall structural strength of the evaporator lower shell, enabling the evaporator lower shell to be stably connected to the evaporator structure. Moreover, since the second part 12 is inclined downward, arranging the reinforcing ribs 4 on the second part 12 can reasonably utilize the space below the second part 12, making the overall structure of the evaporator lower shell more compact.

[0060] It can be understood that the setting positions of the reinforcing part 3 and the reinforcing ribs 4 can be adjusted according to actual needs, as long as the structural strength of the bottom plate 1 can be enhanced.

[0061] Refer to Figure 1 , the present utility model further provides an evaporator structure, including an evaporator body (not shown in the figure) and an evaporator lower shell. The evaporator lower shell is arranged below the evaporator body and connected to the evaporator body. Among them, the drain pipe 13 is arranged below the evaporator body.

[0062] In this way, when the evaporator lower shell is assembled to the evaporator body, since the reinforcing part 3 and the reinforcing ribs 4 can enhance the structural strength of the bottom plate 1, the evaporator lower shell can be prevented from deforming during the assembly and use processes, improving the connection stability and sealing performance between the evaporator lower shell and the evaporator structure, and reducing the later maintenance.

[0063] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model.
