[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0028] Figure 4 , Figure 5 and Figure 6 The embodiment of the evaporator mounting structure of the present invention is shown, and the evaporator mounting structure includes an evaporation base 10, on which a return air port 11 and an air outlet 12 are provided, and a first evaporator mounting surface 13 is formed between the return air port 11 and the air outlet 12. The air inlet surface 14 of the air outlet 12 is arranged at an angle relative to the plane where the return air port 11 is located, and the air inlet surface 14 of the air outlet 12 is inclined toward the direction where the return air port 11 is located.

[0029] By applying the technical solution of the present invention, the air inlet surface 14 of the air outlet 12 is set at an angle relative to the plane where the return air outlet 11 is located, and the air inlet surface 14 of the air outlet 12 is inclined toward the direction where the return air outlet 11 is located, so that the air inlet surface 14 of the air outlet 12 can more easily obtain the airflow entering from the return air outlet 11, thereby helping to reduce the resistance of the evaporation section.

[0030] As a more preferred embodiment, the interception area of ​​the air outlet surface 15 of the air outlet 12 is greater than the interception area of ​​the air inlet surface 14 of the air outlet 12. In this way, the air volume of the air outlet surface 15 of the air outlet 12 can be increased. More preferably, the interception area of ​​the air outlet surface 15 of the air outlet 12 is 2 times or more greater than the interception area of ​​the air inlet surface 14 of the air outlet 12, which helps to reduce the air outlet speed and reduce the air outlet resistance. The air duct resistance is reduced from the existing 230Pa to 150Pa, and the resistance is reduced by 80Pa, which is reduced by 34%.

[0031] like Figure 6 As shown, more preferably, the internal cavity of the air outlet 12 is a gradually expanding structure from the air inlet surface 14 of the air outlet 12 to the air outlet surface 15 of the air outlet 12, so that the static pressure of the air outlet can be recovered.

[0032] As a more preferred embodiment, the extension direction of the internal cavity of the air outlet 12 is perpendicular to the air inlet surface 14 of the air outlet 12, so that the air outlet 12 can be a convex design structure, which helps to strengthen the overall structural strength of the evaporation base 10 and improve reliability. It should be noted that the height of the convex design structure can be appropriately adjusted according to the angle of the air outlet surface 15 of the evaporation air outlet 12.

[0033] More preferably, in the technical solution of the present invention, the first evaporator mounting surface 13 is U-shaped, with the opening facing the air outlet 12, which is conducive to the fan on the air outlet 12 to gather wind and can reduce the length, making the structure compact. As other optional embodiments, the first evaporator mounting surface 13 can also be eight-shaped or L-shaped, etc., which can be flexibly selected according to system matching.

[0034] Since the technical solution of the present invention adopts the above structure, the number of air outlets 12 can be reduced without affecting the refrigeration performance. Figure 5 As shown, the air outlets 12 of the evaporation base 10 of the present invention can be set to 2, and 4 on both sides. That is, one evaporation fan is used on one side, and two evaporation fans are used as a whole. Compared with the existing bus air-conditioning base, the number of air outlets 12 on one side is reduced by half, and the number of evaporation fans can be reduced by half. At the same time, the first evaporator mounting surface 13 is the above structure, which reduces the size of the evaporation base 10 by 26% as a whole. As shown in the following table, the length of the bus air-conditioning base 1 can be reduced by 11.9%, the weight can be reduced by 12%, the performance of the whole machine is not attenuated, and the installation and transportation of the product is convenient. By applying the technical solution of the present invention, by reducing the size of the evaporation base 10, the length of the final bus air-conditioning base can be reduced from the existing 3900mm to the 3438mm of the present invention, and the weight can be reduced from the existing 100kg to the 88kg of the present invention, which can effectively improve the cruising range of the bus.

[0035]

[0036] In this way, the technical solution of the present invention can also solve the problem of long length, heavy weight, and bulky appearance of the bus air conditioner in the prior art, which leads to short vehicle range. In addition, due to the adoption of the above-mentioned structural setting, it is not necessary to open too many air outlets 12 on the evaporator mounting structure, thereby avoiding the problem of lowering the evaporator mounting structure due to too many air outlets 12. At the same time, the above-mentioned structure can also prevent the performance of the whole machine from being attenuated, facilitate installation and operation, reduce the number of evaporation fans, greatly reduce the cost of the bus air conditioner, and improve the competitiveness of the product.

[0037] Another problem with the air conditioner in the prior art is that condensed water is easily scattered from the return air port 11. According to research, it is found that this is due to Figure 2The distance L1 between the first evaporator mounting surface 13 and the return air port 11 shown in FIG is too small. If the distance L1 is too small, the condensed water on the evaporator will easily drop directly from the evaporator to the return air port 11. Figure 5 and Figure 6 As shown, the first evaporator mounting surface 13 is far away from the return air port 11. More preferably, the distance between the first evaporator mounting surface 13 and the return air port 11 is L2, and L2>100mm. In this way, compared with the existing L1, it is increased by 1 times, which can reduce the risk of condensed water spilling from the return air port 11. Among them, L2 can be selected between 100mm and 150mm, which can be flexibly selected according to the arrangement of the fan and the evaporator.

[0038] More preferably, a water baffle 16 is further provided on the evaporation base 10, and the water baffle 16 is located at the air inlet surface 14 of the air outlet 12. The water baffle 16 is used to collect condensed water, and the distance between the water baffle 16 and the return air outlet 11 increases accordingly, further reducing the risk of condensed water spilling from the return air outlet 11. In this way, the problem that condensed water is easily spilled from the return air outlet 11 into the vehicle due to the close distance between the water baffle 16 and the return air outlet 11 can be solved.

[0039] Optionally, in the technical solution of this embodiment, the plane where the air inlet surface 14 of the air outlet 12 is located constitutes the second evaporator mounting surface. When in use, the evaporator is installed between the first evaporator mounting surface 13 and the second evaporator mounting surface.

[0040] Preferably, in the technical solution of this embodiment, there are two air outlets 12 and one return air outlet 11, and one return air outlet 11 is located between the two air outlets 12. The return air outlet 11 is located in the middle of the evaporation base 10, and the two air outlets 12 are distributed on both sides of the return air outlet 11 and close to both sides of the evaporation base 10. An evaporation fan is installed on the air outlet 12 to generate an outlet airflow.

[0041] The technical solution of the present invention also provides a vehicle air conditioner base, which includes the above-mentioned evaporator mounting structure. The above-mentioned evaporator mounting structure can reduce the resistance of the evaporation section, reduce the size and weight of the vehicle air conditioner base, and thus improve the applicability of the vehicle air conditioner base.

[0042] It should be noted that the technical solution of the present invention is particularly suitable for air-conditioning bases for buses.

[0043] like Figure 4 and Figure 5 As shown, the vehicle air conditioner base also includes a connected condenser mounting structure 20, a compressor mounting structure 30 and a controller mounting structure 40. Among them, the condenser mounting structure 20 is used to install the condenser, the compressor mounting structure 30 is used to install the compressor and pipelines, and the controller mounting structure 40 is used to control electrical equipment.

[0044] The technical solution of the present invention also provides a vehicle air conditioner, which includes the above-mentioned vehicle air conditioner base. The above-mentioned vehicle air conditioner base can reduce the size and weight of the vehicle air conditioner and improve the applicability of the vehicle air conditioner.

[0045] It can be seen from the above content that the technical solution of the present invention achieves the following technical effects:

[0046] 1. Reduce the resistance of airflow passing through the evaporation base 10, the air outlet area is increased to 2.26 times of the existing one, and the air outlet resistance is only 56% of the existing one;

[0047] 2. The length of the vehicle air conditioner base is reduced by 11.9%, and the weight is reduced by 12%, achieving a compact and lightweight design, thereby increasing the vehicle's cruising range;

[0048] 3. Since the air outlet 12 is convex and inclined, the structural strength is improved;

[0049] 4. The water baffle 16 is farther away from the return air outlet 11 , which can effectively prevent condensed water from spilling into the vehicle from the return air outlet 11 .

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the embodiments of the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
