Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0036] figure 1 It is a block diagram of a vehicle cold mist spray system according to an embodiment of the present invention. Such as figure 1 As shown, it includes sensor 1 or vehicle communication bus (CAN) 2. Sensor 1 can be set at the engine or intercooler, and the engine water temperature and intercooler temperature can be collected through sensor 1 or vehicle communication bus 2. Sensor 1 or vehicle communication The bus (CAN) 2 is connected to the controller 3, the sensor 1 or the vehicle communication bus (CAN) 2 transmits the detected data to the controller 3, and the controller 3 is connected to the electromagnetic valve of the spray nozzle 4, and the spray nozzle 4 and the The water tank 5 is connected, and the spray nozzle 4 is controlled by the controller 3, and the water after the water mis...

Abstract

The invention discloses a vehicular cold mist spray system and an implementation method thereof. Engine water temperature and intercooling temperature are acquired through a sensor or a vehicle communication bus and compared to optimal operating temperature set by an electric control unit program; spray time and interval of an electric control valve is automatically controlled, mist spray and mist spray interval are implemented dynamically, and flow of cooling water mist is controlled dynamically; if water temperature or post-intercooling temperature is higher than the set temperature, spray time is prolonged, spray interval is shortened, and the flow of misted cooling water is increased; in contrast, if the temperature difference decreases, the spray time is shortened, the spray interval is prolonged, and the flow of misted cooling water is decreased; accordingly, heat dissipation is controlled, and the temperature of a controlled object is kept constant or fluctuating in a certain range.

Description

technical field [0001] The invention relates to the technical field of passenger car electrification, in particular to a cold mist spraying system for a vehicle and an implementation method thereof. Background technique [0002] The current additional cooling measures for intercoolers and water tanks of vehicles are generally water spraying, which is to connect a water pipe to the shower head with a water storage bucket, and control the opening and closing state of the shower head through a manual (or electronically controlled) valve. This method consumes a lot of water. The cooling water flowing through the intercooler and the water tank is in liquid form, and the cooling effect is not ideal compared with the huge water consumption; According to the engine operating conditions, when the engine is under low load, the same flow of cooling water will take away more heat, which may cause the engine operating temperature to be too low, but when the engine is under heavy load, th...
