Abstract

The invention discloses an automobile cooling water circulation control system and method and an automobile. The circulation control system comprises an engine cooling water jacket, a first water pump, a liquid heater and an air-conditioning heat exchanger which are connected through pipelines in an end-to-end mode in sequence. The circulation control system further comprises a second water pump, a first one-way valve, a second one-way valve and a controller, wherein a water inlet of the second water pump is connected with a water outlet of the air-conditioning heat exchanger through a pipeline; a water outlet of the second water pump is connected with a water inlet of the liquid heater through a pipeline; the first one-way valve is arranged on a water inlet or outlet pipeline of the first water pump, and the conducting direction of the first one-way valve is the flowing direction from the engine cooling water jacket to the first water pump; the second one-way valve is arranged on a water inlet or outlet pipeline of the second water pump, and the conducting direction of the second one-way valve is the flowing direction from the second water pump to the liquid heater; the controller controls on and off of the first water pump, the second water pump and the liquid heater. By adopting the circulation control system, heat provided by the liquid heater cannot be emitted by an engine, and therefore the energy utilization efficiency is improved.

Description

Technical field [0001] The invention relates to automobile technology, in particular to an automobile cooling water circulation control system, a control method and an automobile. Background technique [0002] The car’s engine generates a lot of heat during operation. This heat is transported out through the cooling water in the engine cooling water jacket. The car’s air conditioning system often needs to provide heat for the cab. Therefore, the existing technology combines the engine cooling water jacket with The heat exchanger of the air conditioning system is connected to heat the cab with the heat of the cooling water. [0003] figure 1 It is a schematic diagram of the structure of a cooling water circulation system in the prior art, which includes an engine cooling water jacket, a liquid heater, and an air-conditioning heat exchanger that are connected end to end through a pipeline. The liquid heater is integrated with a water pump. The function of the liquid heater is to Whe...
