Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, specifically to an automotive air conditioning evaporator. Background Technology

[0002] The car air conditioning system is an indispensable part of modern cars, providing a comfortable riding environment for drivers and passengers. The evaporator in the air conditioning system is one of the core components. Its main function is to reduce the temperature and remove moisture by absorbing heat from the car, thereby achieving cooling and dehumidification. The working principle of the evaporator is to use low-pressure, low-temperature refrigerant to vaporize inside the evaporator. Through this process, heat in the air is absorbed, achieving the cooling effect.

[0003] Compared to existing evaporators, conventional evaporators have the following drawbacks: they tend to accumulate a lot of dust and other impurities during use. Although they can be cleaned with detergent, this can damage the filtration effect, so they need to be disassembled and replaced regularly. In addition, centralized assembly leads to a decrease in heat dissipation efficiency. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this utility model is an automotive air conditioning evaporator, including an evaporator shell 1. An inner liner bracket 3 is provided on the inner side of the evaporator shell 1 to limit and fix the condenser pipe 5. The upper end of the condenser pipe 5 is provided with a liquid inlet 6 located on the upper side of the evaporator shell 1, and the lower end of the condenser pipe 5 is provided with a liquid outlet 7 located on the lower side of the evaporator shell 1. Protective shell plates 9 are provided at both the front and rear ends of the evaporator shell 1.

[0019] In this embodiment, preferably, the inner side of the inner lining support 3 is provided with a limiting hole groove 4 for locking and limiting the condenser pipe 5, and both ends of the front end of the inner lining support 3 are provided with heat dissipation fins 8, which can limit and fix the condenser pipe 5 and avoid misalignment and shaking during operation.

[0020] In this embodiment, preferably, the condenser tubes 5 are arranged alternately on the inner side of the inner lining support 3, and the condenser tubes 5 form a communication structure with the liquid inlet 6 and the liquid outlet 7 respectively, which can increase the contact range with heat and improve the heat dissipation effect.

[0021] In this embodiment, preferably, the outer end of the condenser tube 5 passes through the cavity groove 12 through the inner side of the protective outer shell plate 9 and extends outward, which can concentrate the heat to dissipate outward and avoid accumulating inside the evaporator shell 1.

[0022] In summary, the condenser tube 5 is first installed inside the inner liner bracket 3 by engaging with the limiting slot 4, and the inner liner bracket 3 is placed inside the evaporator shell 1. The inner liner bracket 3 is provided with support columns at both the upper and lower ends, which can stably limit its position against the inner wall of the evaporator shell 1, so as to maintain the stability of the inner liner bracket 3 and the connection effect of the condenser tube 5. The liquid inlet 6 and liquid outlet 7 provided at the upper and lower ends of the evaporator shell 1 are respectively connected to the condenser tube 5, so that the coolant can enter from the liquid inlet 6, circulate through the condenser tube 5 and then be discharged from the liquid outlet 7.

[0023] The inner lining support 3 has condenser pipes 5 fixedly installed at both the front and rear ends. The condenser pipes 5 pass through the cavity groove 12 and extend outward through the inner side of the protective outer shell plate 9. After the heat is absorbed by the staggered condenser pipes 5, the heat is dissipated outward through the condenser pipes 5, which improves the heat dissipation effect and avoids the accumulation of heat in the evaporator shell 1.

[0024] Example 2 Reference Figure 1 , Figure 4 and Figure 5 As shown in the figure, this is the second embodiment of the present invention, which includes fixed mounting bases 2 fixedly installed at both the left and right ends of the evaporator shell 1, for mounting the evaporator shell 1 as a whole on the fixed surface.

[0025] In this embodiment, preferably, the inner end of the protective outer shell plate 9 is provided with an adhesive rubber sealing strip 10. The protective outer shell plate 9 is engaged with the evaporator outer shell 1 through the rubber sealing strip 10, which can center and limit the inner lining support 3 and prevent it from shaking back and forth.

[0026] In this embodiment, preferably, each of the four inner corners of the protective outer shell plate 9 is provided with a through-hole positioning hole 13, and the inner side of the through-hole positioning hole 13 is provided with a bolt 14 that is threadedly connected to the evaporator shell 1, so that the evaporator shell 1 and the protective outer shell plate 9 can be securely connected and installed.

[0027] In this embodiment, preferably, heat dissipation holes 11 are evenly distributed on the inner side of the protective outer shell plate 9, and a filter screen is installed on the inner side of the heat dissipation holes 11, which can prevent dust or impurities from entering the interior of the evaporator outer shell 1 under the action of the filter screen.

[0028] In summary, in accordance with Embodiment 1, the inner end of the protective outer shell plate 9 is bonded with a rubber sealing strip 10 that engages with the evaporator outer shell 1. This not only prevents the inner lining support 3 from shifting but also provides anti-collision protection for the evaporator outer shell 1. When there is excessive heat, the heat can be dissipated outward through the heat dissipation holes 11 evenly distributed on the inner side of the protective outer shell plate 9. The heat dissipation holes 11 are equipped with filters to remove dust and other impurities, preventing them from entering the evaporator outer shell 1 and causing damage or blockage to components such as the condenser tube 5. The bolts 14 pass through the through-hole positioning holes 13 and are threadedly connected to the evaporator outer shell 1 after passing through the four corners of the protective outer shell plate 9. This facilitates the disassembly and replacement of the entire protective outer shell plate 9 in the later stages, avoiding the phenomenon of poor cleaning effect caused by brushing. Finally, the evaporator outer shell 1 is installed in the designated position using the fixed mounting base 2.

[0029] Example 3 This embodiment is obtained by combining Embodiment 1 and Embodiment 2.

[0030] By expanding the range of heat dissipation and disassembling and replacing easily damaged parts, the absorbed heat can be dissipated over a wider area, thereby improving the operating efficiency of the evaporator.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
