Abstract
The utility model discloses a radiator test device. The device uses a blower fan to generate an air flow, and then the air flow passes through a stabilization segment, a contraction segment, a test room, and an expansion segment in order. The cross sections of the stabilization segment, the contraction segment, and the expansion segment are circular, and the test room is a room which is peripherally sealed. The test device is rapid in testing and strong in generality, and can precisely measure the data, so the testing time is effectively reduced, and the testing efficiency is improved. Besides, the test device is simple in structure and low in assembly cost, so the testing cost of the radiator test is greatly saved.
Description
Technical field
The utility model relates to a kind of testing equipment, in particular, relates to a kind of wind tunnel test equipment of automobile radiators.
Background technology
Automobile radiators is to guarantee motor car engine requisite strength member of continuous working in suitable temperature range.The mensuration of automobile radiators performance parameter has been stipulated test method and testing equipment thereof in the industry standard (JB2293-78) at present.
The major part of said testing equipment is called " air duct " in the standard, and " air duct " during to the test of the heating radiator of different size, need otherwise designed or some test sections that extend, universal performance is poor, has increased experimentation cost greatly.For changing the thing that test section is a suitable trouble, increased the working strength of testing crew virtually when testing for the heating radiator of different model, the experiment work that also makes is heavy.Simultaneously the test section face is through after expansion or shrinking, the residing velocity field of heating radiator with will be different on the uniform cross section straight tube; Expansion or the angle of shrinking also can be different, and its velocity field is also different; Thereby, the data precision of radiator performance experimental test is affected.
The utility model content
The utility model technical matters to be solved is that realization is a kind of simple in structure, easy to assembly, measures accurate heating radiator testing equipment.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of heating radiator testing equipment; This equipment produces air-flow by blower fan; Air-flow passes through stable section, contraction section, test bay and diffuser successively, and described stable section, contraction section and diffuser cross section are circular, the room that described test bay seals around being.
Described stable section inlet end is horn-like, and inside is equipped with fairing, honeycomb and damping screen.
Described honeycomb is two-layer sexangle damping screen, is respectively 20 orders and 22 orders.
Described contraction section is along the diminishing canalis spinalis of airflow direction internal diameter, and contraction section and test bay connecting portion have one section flat tube.
Be provided with frame of axes, water circulation system and heating system fixing and that regulate heating radiator in the described test bay.
It is interior along on the track of wind direction direction layout that described frame of axes is arranged on test bay, and described frame of axes is provided with lifting heating radiator stone tongs.
Described test bay is provided with the door that confession is manipulated.
Described blower fan and diffuser flexible joint.
The advantage of the utility model is that this testing equipment test is quick, highly versatile, measurement data precision simultaneously; Can effectively practice thrift test period, improve test efficiency, and this device structure is simple; Assembly cost is low, can practice thrift the experimentation cost of heating radiator test greatly.
