Embodiment Construction
[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0030] see Figure 1-7 As shown, a pure electric bus battery cooling system includes a bracket 1, a cooling frame 2 and a fixing mechanism 3, the cooling frame 2 is fixed on the bracket 1, the fixing mechanism 3 is fixed on the top of the bracket 1, and the inner walls of the three sides of the cooling frame 2 are Several nozzles 25 are installed, and the inside of the cooling frame 2 is hollow and filled with water. A water pump 22 is fixedly installed on the inner wall of one side of the cooling frame 2. The water pump 22...

The invention discloses a battery cooling system for a pure electric bus. The battery cooling system for the pure electric bus comprises a bracket, a cooling frame and a fixing mechanism, wherein thecooling frame is fixed on the bracket, the fixing mechanism is fixed on the top of the bracket, a plurality of spray nozzles are respectively installed on the inner walls of three sides of the coolingframe, and the interior of the cooling bracket is hollow and filled with water; a water pump is fixedly installed on the inner wall of one side of the cooling frame, the water pump is connected withthe cooling frame through a pipeline accessed into the interior of the cooling frame, and the water pump is respectively connected with each spray nozzle through a plurality of separate pipelines; a temperature sensor is fixedly installed on the top of the water pump. The battery cooling system can solve the problems that the existing battery cooling system of the pure electric bus has poor cooling performance and lacks components for emergency treatment when the battery is overloaded and self-ignites, so the battery cooling system exists certain potential safety hazards, and after the coolingsystem is assembled with the battery, the stability performance of an overall structure is poor.
Description
technical field [0001] The invention relates to the field of battery cooling for passenger cars, in particular to a battery cooling system for pure electric passenger cars and a control method thereof. Background technique [0002] Pure electric bus batteries often need to be equipped with a cooling system after installation. The cooling system is used to cool down the pure electric bus batteries to ensure the safety performance of the batteries. However, the existing pure electric bus battery cooling system is used There are still some defects, firstly, the cooling performance is not good, and secondly, there is a lack of emergency treatment parts when the battery is overloaded and spontaneously ignites, so there are certain safety hazards, and after the cooling system is assembled with the battery, the overall structure The stability performance is not good. [0003] The patent with publication number: CN207134448U discloses a battery cooling system. Compared with this ap...
