[0002] The dual-source heat pump for electric vehicles is a highly efficient air-conditioning system that can significantly reduce energy consumption and increase driving range. The core of dual-source heat pump technology is its ability to utilize multiple heat sources to meet the cooling and heating needs of electric vehicles. This technology combines two modules: direct heat pump and indirect heat pump. The direct heat pump is mainly used for cabin heating, and quickly increases the temperature inside the car through efficient refrigerant circulation; while the indirect heat pump takes into account the heating needs of the cabin and the battery, and uses coolant to conduct heat. In addition, the dual-source heat pump may also combine multiple heat sources such as waste heat from the electric drive air-conditioning compressor and PTC heating to optimize the battery heating speed and efficiency through synergy; In the past, dual-source heat pumps were suitable for electric vehicles.

[0025] Working principle: first, install a fan at the front end of the evaporator box 2, and install the air outlet bin 79 next to the door handle, start the compressor 11, and make the compressor 11 heat the in-car condenser 1 through the No. 5 pipe 12, and the fan at the front end of the evaporator box 2 blows air to the evaporator box 2 and the in-car condenser 1, so that the wind passes through the in-car condenser 1 to form hot air, and then the hot air passes through the fixing plate 71, and the hot air passes through the air permeable groove 72, so that the fixing plate 71 reduces the amount of air that blocks the hot air from entering the car, and the hot air enters the collection bin 75, so that the hot air contacts the spoiler block 711, so that the hot air passes through the main spoiler 712, the auxiliary spoiler 713, and the main spoiler 712, the auxiliary spoiler The shape of the plate 713 is wavy, so that when the hot air passes through the spoiler block 711, it forms a rotation dispersion, and the hot air flows into the connecting chamber 76, and then the hot air contacts the spiral frame 714, so that the spiral frame 714 accelerates the rotation of the hot air by virtue of its shape, so that the hot air flows forward quickly, and when the hot air contacts the spoiler block 711, the main spoiler plate 712 and the auxiliary spoiler plate 713 rotate and disperse the hot air, and after the hot air contacts the spiral frame 714, the hot air accelerates the rotation and circulation speed, so as to achieve the purpose of facilitating the rapid circulation of the hot air, and change the form of the gentle flow of the hot air to achieve rapid flow, and then the hot air passes through the diversion pipe 78 The hot air flows into the air outlet bin 79, and the plug flow block 718 disperses the hot air to the surroundings. At the same time, the hot air contacts the diverter plate 719. Since the width of the diverter plate 719 gradually changes, the hot air is evenly dispersed by several groups of diverter plates 719, and the hot air flows outward from the air outlet frame 715 evenly and in a large area, so that the hot air blows to the door handle, so that the hot air accurately heats the door handle, so that the door handle is quickly thawed. When the hot air blows to the plug flow block 718, the plug flow block 718 disperses the hot air to the surroundings by its own shape, and the hot air contacts the several groups of diverter plates 719, and the width of the diverter plate 719 gradually changes, so that the several groups The spoiler 719 disperses the hot air evenly, so that the hot air can flow outward from the air outlet frame 715 evenly and over a large area, so that the hot air blows toward the door handle, and the hot air accurately heats the door handle, so that the door handle is quickly thawed. The hot air is rotated and dispersed by the main spoiler 712 and the auxiliary spoiler 713 to form multiple wind paths for winding flow. After contacting the spiral frame 714, the hot air accelerates the rotation and circulation speed, so that the heat of the hot air is kept warm to the greatest extent. Several groups of split plates 719 disperse the hot air evenly, so that the hot air in insulation quickly dissipates heat outward, thereby accelerating the heating of the door handle.
