Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention relates to an automobile air conditioner with an engine waste heat recovery function, which comprises a diffuser pipe 4, wherein any end of the diffuser pipe 4 is communicated with a mixing pipe 3, one end of the mixing pipe 3, which is far away from the diffuser pipe 4, is communicated with a throat pipe 2, one end of the throat pipe 2, which is far away from the mixing pipe 3, is communicated with a nozzle 7, the power of a fan is from electricity converted by automobile engine waste heat recovery, the tail end of the nozzle 7 is communicated with the fan 1, the lower side of the throat pipe 2 is communicated with an atomization device, the atomization device is communicated with a hot water circulating pipe, and the hot water circulating pipe is connected with an automobile engine.
As shown in fig. 3, 4 and 5, the atomization device comprises a drainage tube 6, one end of the drainage tube 6 is communicated with the throat 2, the other end of the drainage tube 6 is communicated with an atomization water tank 5, an atomizer 8 is arranged in the atomization water tank 5, and the atomization water tank 5 is communicated with a hot water circulation tube. The water in the atomization water tank 5 is atomized by the atomizer 8, and the atomized water enters the throat 2 through the drainage tube 6. The circulating pipe is connected to the automobile engine to absorb the residual heat of the engine. The hot water circulating pipe is provided with a valve. A water level monitor is arranged in the atomization water tank 5. The atomization water tank 5 is provided with a water inlet which is connected to the outlet of a water filter, and the inlet of the water filter is connected with the outlet of a soft water instrument. The drainage tube 6 is a tube with a circular section. The mixing pipe 3 and the diffuser pipe 4 are both variable cross-section rectangular pipes with the same cone apex angle.
The invention relates to an automobile air conditioner with an engine waste heat recovery function. The engine waste heat power generation provides power for the fan at low speed or idling, so that the pressure of the fan from the nozzle to the throat is reduced to the minimum to form negative pressure. The water mist enters the throat pipe through the drainage pipe under the action of negative pressure to be mixed with air, and then enters the mixing pipe to be fully mixed. The water evaporates and absorbs heat in the process of mixing the air and the water mist, and the temperature of the air is reduced. The air flow enters the diffuser pipe and is pressurized and sent out. When the water level of the atomization water tank is reduced to the lowest working liquid level height, the water level alarm starts water injection. In spring and autumn, the atomizer can be started according to outdoor air temperature, or the atomizer can be used only for ventilation without being started. When the device is used in winter, in dry areas, the waste heat discharged by an automobile engine can be used for heating water in the atomization water tank, air supply is heated and humidified, and the valve of the hot water circulating pipe in the atomization water tank is closed in summer.
The invention relates to an automobile air conditioner with an engine waste heat recovery function, which has the advantages that: the design is different from the traditional mechanical refrigeration, a compressor, a condenser and other refrigeration devices are not needed, and the initial investment is small; the system adopts the ultrasonic direct evaporative cooling technology, uses water as a refrigerant, and achieves the purposes of energy conservation and environmental protection. When the air conditioner runs at a low speed or idles, the waste heat generated by the engine is recovered to generate electricity to provide power for the fan so as to maintain the normal operation of the air conditioner. The straight-flow type fresh air guarantees the comfort and sanitary requirements in the vehicle.
The atomizer adopts ultrasonic atomization device, and the diameter that utilizes ultrasonic atomization device to produce the liquid drop can reach 1 ~ 5 mu m, and the area of contact of water smoke and air is big, and the evaporation cooling process is more abundant, and cooling efficiency improves, and the equipment size is littleer.
The taper angle of the reducing pipe is 30-60 degrees, and the taper angle of the diffuser pipe is 10-30 degrees. In order to avoid the flow loss and the pressure sudden change caused by the sudden change of the pipeline section at the connecting part of the reducing pipe, the mixing pipe and the diffuser pipe, the cone angles of the mixing pipe and the diffuser pipe are the same, and the inner diameters of the joints at the positions are kept consistent.
The invention relates to an automobile air conditioner with an engine waste heat recovery function, which combines an engine waste heat to electricity technology, utilizes ultrasonic waves to directly evaporate and cool, is designed by the characteristic of an air ejector structure, takes water as a refrigerant, avoids using an automobile engine to provide power, maintains air cooling treatment by waste heat power generation and sends the air cooling treatment into an automobile.
