DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0024] See also Figures 1 to 3 The utility model provides a connection structure between an evaporator 1 and a chassis 2, characterized in that it includes:
[0025] The evaporator 1 has a mounting cavity which is closed on all sides and open on two opposite sides;
[0026] A chassis 2, disposed at one open end of the mounting cavity;
[0027] A plurality of connecting plates 3 are provided to connect the chassis 2 and the other open end of the evaporator 1. The connecting plates 3 include a first connecting section 4 and a second connecting section 5 which are staggered in the up-down direction, and a third connecting section 6 which connects the first connecting section 4 and the second connecting section 5. A notch 7 is formed between the first connecting section 4 and the third connecting section 6 for being clamped on the evaporator 1. The second connecting section 5 is arranged perpendicular to the third connecting section 6 and has a fixed point for being fixed on the chassis 2.
[0028] In this embodiment, the evaporator 1 has an installation cavity which is closed on all sides and relatively open at both ends, so as to facilitate the installation in coordination with the chassis 2. The chassis 2 is arranged at one open end of the installation cavity of the evaporator 1 as a supporting basis. A plurality of connecting plates 3 are provided at the other open end of the evaporator 1. The connecting plates 3 include a first connecting section 4 and a second connecting section 5 which are staggered in the up-down direction. The first connecting section 4 is used to be clamped on the open end of the evaporator 1 at the top, and the second connecting section 5 is used to be fixed to the open end at the bottom of the evaporator 1. The staggered arrangement of the first connecting section 4 and the second connecting section 5 enables the installation plate to fix the evaporator 1 in the up-down direction and the front-back direction, thereby enhancing the stability and adaptability of the connection. A third connecting section 6 is also provided between the first connecting section 4 and the second connecting section 5. The three connecting sections 6 are used to connect the first connecting section 4 and the second connecting section 5, and as a transition section, they are abutted against the middle of the evaporator 1, and cooperate with the first connecting section 4 and the second connecting section 5 to form a stable three-axis support structure. At the same time, the second connecting section 5 is formed with a fixed point located below the evaporator 1, which is used to fix the evaporator 1 and the chassis 2 together. A notch 7 is constructed between the first connecting section 4 and the third connecting section 6 for being clamped on the top of the evaporator 1. After the bottom of the evaporator 1 is fixed to the chassis 2 through the fixed point, the notch 7 is clamped on the top of the evaporator 1, so that the evaporator 1 can be fixed on the chassis 2. This fixing method only requires one fixed point, is simple to assemble, and is easy to install, and can prevent the evaporator 1 from being displaced during transportation of the entire machine.
[0029] The first connecting section 4 includes a horizontal end 401 and a vertical end 402 connected to each other. The horizontal end 401 is located between the third connecting section 6 and the vertical end 402, and the gap 7 is formed therebetween.
[0030] In this embodiment, the notch 7 formed by the first connecting section 4 can be used as a movable fixing point to fix the evaporator 1. The first connecting section 4 includes a horizontal end 401 and a vertical end 402 that are connected. The horizontal end 401 is located between the third connecting section 6 and the vertical end 402, so that the third connecting section 6, the horizontal end 401 and the vertical end 402 can limit the evaporator 1 in three directions.
[0031] The third connecting section 6 and the vertical end 402 are respectively in contact with the inner and outer end surfaces of the evaporator 1 , and the horizontal end 401 is in contact with the top of the evaporator 1 .
[0032] In this embodiment, the third connecting section 6 is in close contact with the inner end surface of the evaporator 1, ensuring effective support from the bottom to the inside of the evaporator 1. At the same time, the vertical end 402 is abutted against the outer end surface of the evaporator 1. This inside-outside clamping method significantly enhances the stability of the connection and prevents the lateral movement of the evaporator 1. The horizontal end 401 is abutted against the top of the evaporator 1, further consolidating the stability of the overall structure, and also increasing the ability to disperse the upper stress through the support point at the top. The close contact in three directions (inside, outside and top) ensures a firm connection between the chassis 2 and the evaporator 1.
[0033] The fixing points are a plurality of threaded holes 501 disposed on the second connecting section 5 .
[0034] In this embodiment, the threaded hole 501 simplifies the installation process. The technician only needs to screw the matching screws into the preset threaded hole 501 to complete the fixation. At the same time, if adjustment or disassembly is required, it can also be carried out quickly and conveniently, which improves the flexibility of maintenance. Moreover, since this connection structure has only one fixed point, the convenience of installation and disassembly is further improved.
[0035] The third connecting section 6 is provided with a plurality of ventilation holes 601 at intervals. The ventilation holes 601 are strip-shaped structures and are arranged along the length direction of the third connecting section 6 .
[0036] In this embodiment, the provision of the ventilation holes 601 can promote air circulation, which helps to exchange cold and hot gases and improve heat exchange efficiency during the operation of the evaporator 1. The strip-shaped ventilation holes 601 achieve a lightweight design by removing part of the material while maintaining the structural strength, which helps to reduce the overall weight of the equipment.
[0037] A reinforcing rib 8 is provided between two adjacent ventilation holes 601 .
[0038] In this embodiment, a reinforcing rib 8 structure is added between two adjacent ventilation holes 601. The reinforcing rib 8 not only plays a role of connection and support, but also effectively enhances the overall rigidity and stability of the third connecting section 6, especially when there is thinning material in the ventilation holes 601, which can effectively prevent structural deformation.
[0039] The third connecting section 6 is provided with a plurality of first bending edges 9 along its length direction, and the first bending edges 9 extend toward the second connecting section 5 .
[0040] In this embodiment, the first bending edge 9 increases the supporting capacity of the third connecting segment 6 in the vertical direction, which is equivalent to building multiple "beams" into the third connecting segment 6, significantly improving the rigidity and bending resistance of the third connecting segment 6, and maintaining good shape stability even when squeezed or twisted by external force.
[0041] The second connecting section 5 is provided with a plurality of second bending edges 10 along its width direction, and the second bending edges 10 extend upward.
[0042] In this embodiment, the second connecting section 5 is provided with a plurality of second bending edges 10 along its width direction. The second bending edges 10 extend upward. By adding a vertically upward bending structure to the second connecting section 5, the upward extension of the second bending edge 10 increases the supporting force of the second connecting section 5 in the vertical direction, effectively resisting sagging or deformation caused by gravity or external force. The second bending edge 10 can improve the stress transfer path within the second connecting section 5, and cooperate with the third connecting section 6 vertically arranged thereto to make the force distribution more uniform, reduce local stress concentration, and enhance the durability of the overall structure.
[0043] A connection point between the first connection segment 4 and the third connection segment 6 and a connection point between the second connection segment 5 and the third connection segment 6 are provided with a rounded structure.
[0044] In this embodiment, in order to enhance the strength of the first connecting segment 4, the second connecting segment 5 and the third connecting segment 6, rounded corner structures are provided at their connections. The rounded corners can effectively alleviate the stress concentration phenomenon at the connections. Compared with the right-angle or sharp-angle design, the rounded corner structure can disperse the stress more evenly when subjected to external force, reduce the risk of cracks or fractures, and enhance the toughness and strength of the overall structure.
[0045] This embodiment also proposes an air conditioner, which includes the connection structure between the evaporator 1 and the chassis 2 mentioned above. The specific structure of the air conditioner refers to the above embodiment. Since this air conditioner adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
