Problems solved by technology
[0003] The existing battery cooling system needs to be equipped with an independent and complete air conditioning system (including compressors, evaporators, condensers, fans, etc.) to achieve battery temperature control. air conditioners, resulting in problems such as low system utilization, high cost, and large layout space. Especially in the case of limited overall space, it is difficult to achieve reasonable and effective battery layout.

The invention provides a water-cooling heat dissipation system for a vehicle-mounted battery and a water-cooling heat dissipation method for the battery. The water-cooling heat dissipation system for the vehicle-mounted battery comprises a cooling pipeline used for heat dissipation of the vehicle-mounted battery, wherein the cooling pipeline comprises a heat absorption section used for absorbing heat of the vehicle-mounted battery and a heat discharge section used for discharging the heat of the heat absorption section; the heat discharge section is arranged in a compartment or an air-conditioning duct; and the heat discharge section is provided with an air-inducing part used for inducing compartment air or air-conditioning wind to perform system heat exchange. The water-cooling heat dissipation method for the battery comprises the following steps of: 1, inputting a cooling liquid to absorb the heat of the battery; and 2, inducing the compartment air to perform heat exchange on the cooling liquid which absorbs the heat of the battery. The system has the advantages of high system integration level, compact layout and low cost.
Description
Technical field [0001] The invention relates to the technical field of battery heat dissipation, in particular to a vehicle-mounted battery water cooling system and a battery water cooling method. Background technique [0002] Under the environment of energy saving and emission reduction, hybrid electric vehicles and pure electric vehicles driven by power batteries as energy sources are widely used. During the driving of electric vehicles, complex chemical reactions occur during charging and discharging of power batteries, which easily accumulate a large amount of heat inside the battery, causing the battery operating temperature to rise, battery performance degradation (reduced battery conversion efficiency and cycle life, etc.) and battery burning Explosion and other issues, effectively solving the battery heat dissipation problem is very important for the safe driving of electric vehicles. [0003] The existing battery cooling system needs to be equipped with an independent and...
