The utility model provides a cooling water circulation structure of a vehicle. The structure is provided with a first cooling water circulation loop, a second cooling water circulation loop, a first water pump and a second water pump. At least a cooling part of the power source is arranged in the first cooling water circulation loop; the second cooling water circulation loop is at least provided with a heat exchange device; the cooling water circulation structure is provided with a control device for controlling the drainage pressure proportion of the first water pump and the second water pumpcorresponding to the temperature of cooling water. The temperature controller is used for opening or closing the cooling water channel corresponding to the temperature of the cooling water; when thetemperature of the cooling water of the cooling part of the power source is higher than a specified temperature, the first cooling water circulation loop is communicated with the second cooling watercirculation loop, and when
