[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0017] like Figure 1 As shown, a battery thermal management system with integrated driver's seat air conditioning includes a defroster 1 connected to a battery liquid cooling unit 3 via a hose 2. The defroster 1 provides rapid defrosting and demisting, and regulates the driver's seat temperature. The battery liquid cooling unit 3 cools the battery pack, and the hose 2 allows for decentralized placement, providing high flexibility.

[0018] like Figure 2 As shown, the battery liquid cooling unit 3 includes a battery liquid cooling unit frame, on which a compressor 11 is arranged, and the compressor 11 is provided with a compressor exhaust pipe 12 and a compressor return air pipe 8, wherein the compressor exhaust pipe 12 is connected to the condensing core assembly 13, and a condensing fan 5 is arranged above the condensing core assembly 13, and a fan cover 4 is arranged around the condensing fan 5, and the condensing core assembly 13 and the condensing fan 5 are fixed to the fan cover 4 by bolts; the condensing core assembly 13 is connected to the dryer welding assembly 6, and the dryer welding assembly 6 is respectively connected to the defroster 1 and the plate heat exchanger assembly 7.

[0019] Furthermore, the battery liquid cooling unit frame includes a first battery liquid cooling unit frame 9 and a second battery liquid cooling unit frame 10, and the first battery liquid cooling unit frame 9 and the second battery liquid cooling unit frame 10 are fixed together by bolts, which is convenient for product installation and maintenance, and improves product assembly and after-sales maintenance efficiency. It should be noted that the first battery liquid cooling unit frame 9 and the second battery liquid cooling unit frame 10 both adopt a frame structure, and can be welded according to the spatial position during assembly. In the present utility model, the drying welding assembly 6 and the plate heat exchanger assembly 7 are assembled on the first battery liquid cooling unit frame 9, the compressor 11 is assembled on the lower part of the second battery liquid cooling unit frame 10, and the condensing core assembly 13 and the condensing fan 5 are assembled above the second battery liquid cooling unit frame 10.

[0021] Furthermore, the dryer welding assembly 6 is conventional, and includes a drying tank and an expansion valve, etc.

[0022] The operating principle of the system of the present invention is as follows: the refrigerant is compressed by the compressor and enters the condenser. After condensation in the condenser, it enters the drying tank and expansion valve of the dryer welding assembly 6. After throttling and reducing the pressure by the expansion valve, part of the low-temperature and low-pressure liquid refrigerant enters the defroster 1, and the other part enters the plate heat exchanger assembly 7 to realize heat exchange with the high-temperature liquid in the battery cooling pipeline in the plate heat exchanger, thereby realizing heat dissipation of the bus battery.

[0023] This utility model integrates battery thermal management and driver area heating and cooling. The two are connected by a hose. The defroster and battery liquid cooling unit can be arranged in a dispersed manner. The installation and layout are flexible and convenient, and the space occupied by the entire vehicle is small. It can be applied to more models.
