Detailed Description
As shown in fig. 2, the cooling and heating water path structure for SUV battery with P1+ P3 frame of the present invention includes a battery heating pipeline and a battery cooling pipeline.
The battery heating pipeline comprises a heat exchanger and an electromagnetic valve I which is connected in series on the outer side of one end of the heat exchanger, and heat medium inlets and outlets at two ends of the heat exchanger are respectively connected with an engine warm air water outlet pipe and an engine warm air water return pipe. Specifically, a heat medium inlet of the heat exchanger is connected with a warm air outlet pipe of the engine, and a heat medium outlet of the heat exchanger is connected with a warm air return pipe of the engine.
The battery cooling pipeline comprises a battery cooler, and refrigerant inlets and outlets at two ends of the battery cooler are respectively connected with the automobile refrigerant pipeline. The battery heating pipeline is connected with the battery cooling pipeline in parallel, one end of the parallel pipeline is connected with the power battery, and the other end of the parallel pipeline is connected with the electronic water pump and then connected with the power battery. The two ends of the electronic water pump are also connected with expansion kettles in parallel to form a small exhaust circulation water path.
In this embodiment, the automobile refrigerant connecting pipeline includes an air conditioner compressor, a condenser, an evaporator and an expansion valve, the air conditioner compressor and the condenser are connected in series to form an automobile refrigerant pipeline i, the evaporator and the expansion valve are connected in series to form an automobile refrigerant pipeline ii, the automobile refrigerant pipeline i and the automobile refrigerant pipeline ii are connected in parallel, then are connected in series with an electromagnetic valve ii, and then are respectively connected with refrigerant inlets and outlets at two ends of the battery cooler. When the automobile refrigerant pipeline I and the automobile refrigerant pipeline II are connected, the water outlet end of a condenser of the automobile refrigerant pipeline I and the water outlet end of an expansion valve of the automobile refrigerant pipeline II are respectively connected with a tee joint and then connected with one interface of the electromagnetic valve II, and the other interface of the electromagnetic valve II is connected with a refrigerant inlet of the battery cooler; and the water inlet end of an air conditioner compressor of the automobile refrigerant pipeline I and the water inlet end of an evaporator of the automobile refrigerant pipeline II are respectively connected with the tee joint and then connected with a refrigerant outlet of the battery cooler.
