Technical field
The utility model relates to on-board air conditioner detection field, is specifically related to a kind of on-board air conditioner heat exchanger inner hexagon equipment.
Background technology
Whether heat exchanger is the critical piece of on-board air conditioner, and the quality of heat exchanger directly affects the working effect of on-board air conditioner, therefore needing to detect on-board air conditioner when producing, detecting it and leaking.Although also have device or the equipment of the whether interior leakage of the on-board air conditioner heat exchanger of special detection at present, its ubiquity detects complex operation, precision is low, the time is long, poor stability, energy consumption are high, etc. defect.Therefore, be necessary a kind of operation is provided and sets the heat exchanger inner hexagon equipment simple, detection time is short, precision high stability is high, energy consumption is low.
Summary of the invention
The purpose of this utility model is just to provide a kind of on-board air conditioner heat exchanger inner hexagon equipment, and it can realize the quick detection to leaking in heat exchanger, and operation and setting is simple, accuracy of detection is high, stability is high, energy consumption is low.
For achieving the above object, the utility model adopts following technical scheme to implement:
A kind of on-board air conditioner heat exchanger inner hexagon equipment, it is characterized in that: comprise the ultrasonic generator of heat exchanger entrance place setting and the ultrasonic probe, ultrasonic receiver of heat exchanger outlet place setting, ultrasonic probe, ultrasonic receiver and the ultrasound wave accepted it carry out analyzing and processing and judge that the whether interior APU leaked of heat exchanger is connected, and APU is connected with the display device in order to show testing result.
Concrete scheme is:
APU is also connected with warning device.The amplifier that ultrasonic probe, ultrasonic receiver comprises microphone and is connected with the output terminal of microphone, amplifier is connected with APU.
In such scheme, adopt ultrasound wave to detect leaking in heat exchanger, it is simple to operate, and the accuracy of detection that ultrasound wave internally leaks is high and detect rapidly, effectively improves the detection efficiency of heat exchanger.
Accompanying drawing explanation
Fig. 1 is the overhaul flow chart of the utility model equipment;
Fig. 2 is assembling schematic diagram of the present utility model.
Embodiment
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is specifically described.Should be appreciated that following word only in order to describe one or more concrete embodiments of the present utility model, considered critical is not carried out to the protection domain that the utility model is specifically asked.
For improving detection efficiency and precision, the utility model adopts following technical scheme to operate, a kind of on-board air conditioner heat exchanger inner hexagon equipment, comprise the ultrasonic generator 10 of heat exchanger 40 porch setting and the ultrasonic probe, ultrasonic receiver 50 of heat exchanger 40 exit setting, ultrasonic probe, ultrasonic receiver 50 and the ultrasound wave accepted it carry out analyzing and processing and judge that the whether interior APU leaked of heat exchanger 40 is connected 60, and APU 60 is connected with the display device in order to show testing result.
The principle that the utility model detects is detect sound wave and the integrated value that measure whether consistent with setting exemplar by time of core body whether between maximal value and minimum value, and whether the deviate of integration is in the deviate of 3 times.
Further scheme is: APU 60 is also connected with warning device.
The amplifier 20 that ultrasonic probe, ultrasonic receiver comprises microphone 30 and is connected with the output terminal of microphone 30, amplifier 20 is connected with APU, and the input end of microphone 30 is connected with the inner chamber of heat exchanger 40.
More specifically scheme is: ultrasonic generator 10 comprises power amplifier and Full-frequency trumpet, the model FOSTEX FE126EN of Full-frequency trumpet, and the model of power amplifier is BOSE 1705II; Microphone 30 is the little open country of microphone, model MI-1235; APU 60 is Mitsubishi data collection and analysis device MLQIC, model IU2-5M10; Amplifier 20 is little open country, model SR-2210.Display device comprises red led and green indicating lamp.
The ultrasound wave sent by ultrasonic generator 10 enters heat exchanger 40, accept sound wave in exit by microphone and convert it into electric signal by amplifier, then judge whether heat exchanger 40 inside exists leakage by data processing, test result display waveform figure.Identification method: detect after terminating and can show by pilot lamp on equipment, qualified is green indicating lamp, and defective red led shows and has alarm sound to send.The entrance and exit place of heat exchanger 40 is respectively arranged with joint, arranges fairlead respectively and be connected with microphone and ultrasonic probe, ultrasonic receiver in the middle part of joint.
Adopt the said equipment to carry out detection to leakage in heat exchanger 40 and there is following advantage: Detection accuracy is high, recall rate 99.999%; Accuracy of detection is high, can area of detection 0.15mm
2above small opening; Detection time is short, 3-5 second/platform; Can to defective products automatic data collection, store, be easy to produce bad analysis; Equipment volume is little, lightweight, easily movement; Easy to operate, easily debug; Energy is corresponding various vehicle product simultaneously, can realize remodeling fast; Low-loss, energy-conserving product, only need provide the civil power of 220V.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; to know in the utility model after contents; under the prerequisite not departing from the utility model principle; can also make some equal conversion to it and substitute, these convert on an equal basis and substitute and also should be considered as belonging to protection domain of the present utility model.
