[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1-4 As shown, the utility model is a layout structure of a battery air-conditioning unit cooling system, including a frame assembly, a transition connection bracket and a BMS mounting frame assembly. The battery air-conditioning unit is arranged in the BMS mounting frame assembly, and is installed on the outside of the frame assembly along with the BMS mounting frame assembly through no less than two transition connection brackets, so as to simply and quickly install the battery air-conditioning unit.

[0025] Specifically, a plurality of transition connection brackets 2 are fixed to the frame assembly 1 in an orderly manner by means of a plurality of first hexagonal flange bolts 3 and a plurality of first nuts 4, thus constituting a fixed base of the battery air conditioning unit cooling system; a BMS mounting frame assembly 5 is provided on the transition connection bracket 2, and the BMS mounting frame assembly 5 is fixed to the transition connection bracket 2 in an orderly manner by means of a plurality of first hexagonal flange bolts 3 and a plurality of first nuts 4; a battery air conditioning unit 9 is connected to the BMS mounting frame assembly 5 by means of a plurality of second hexagonal flange bolts 10 and a plurality of second nuts 11, and is placed in the BMS mounting frame assembly, so as to install the battery air conditioning unit on the frame assembly.

[0026] The BMS mounting frame assembly 5 includes a BMS mounting frame, an upper protective cover 6, a side protective cover I 7 and a side protective cover II 12, wherein the upper protective cover is arranged on the upper side of the BMS mounting frame, the side protective cover I is arranged on the left and right sides of the BMS mounting frame, the side protective cover II is arranged on the front side of the BMS mounting frame, and the rear side of the BMS mounting frame is shielded by the frame assembly, so the side protective cover may not be arranged; of course, the side protective cover II may also be arranged on the rear side of the BMS mounting frame, and this embodiment does not limit this.

[0027] Furthermore, the upper protective cover 6 , the side protective cover I 7 and the side protective cover II 12 are fixed to the BMS mounting frame by a plurality of third hexagonal flange bolts 8 .

[0028] Preferably, the BMS installation frame assembly 5 has an upper protective cover 6, a side protective cover I 7 and a side protective cover II 12, which can effectively improve the reliability of the battery air conditioning unit 9 during actual use; the upper protective cover, the side protective cover I and / or the side protective cover II are provided with shutters. In this embodiment, a certain degree of shutters are opened on the side protective cover II 12 to prevent hot air from blowing directly on pedestrians, and at the same time, it can also avoid the situation where the airflow field of the entire battery air conditioning unit is not good due to over-dense protection, resulting in reduced heat dissipation performance of the whole unit.

[0029] Furthermore, the BMS installation frame is a square frame structure so as to install the battery air conditioning unit 9. The transition connection bracket is a cylindrical section structure, wherein the side facing the frame assembly 1 is the cut plane, and the side facing the BMS installation frame assembly is the cylindrical arc surface. Of course, the transition connection bracket can also be an isosceles trapezoidal structure, and the side facing the frame assembly 1 is longer than the side facing the BMS installation frame assembly, so that the transition connection bracket can be stably installed on the frame assembly, and will not affect the assembly of the BMS installation frame assembly and the transition connection bracket and then installed on the frame assembly.

[0030] The layout of the battery air conditioning unit cooling system can be optimized through CAE finite element analysis theoretical strength.

[0031] During specific implementation, sub-packaging can be carried out to improve assembly efficiency. After the BMS installation frame assembly 5 is installed, the BMS installation frame assembly 5 and the transition connection bracket 2 are installed and packaged into a module. After the module is selected online, it is assembled on the frame assembly 1, which can improve assembly efficiency and production rhythm.

[0032] The battery air-conditioning unit cooling system has various layout structures and can be installed anywhere in the vehicle if space permits, thereby improving the layout, versatility and ease of installation and maintenance of the battery cooling system. It can also reduce the height of the vehicle, making the layout flexible and preventing the rear battery pack of a large-capacity vehicle from being too high, thereby affecting the vehicle's passability. It also realizes modularization and generalization in actual use. The battery air-conditioning unit cooling system has a simple and reliable layout structure and low maintenance cost.

[0033] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
