Description
Technical field
The utility model relates to the cooling structure of manometric test electric pressure scaner.
Background technique
In wind tunnel test, utilize the surperficial pressurized situation of the pressure tap measurement model of model surface in flow field, for strength of aircraft design provides initial data, the type test is called that wind tunnel pressure measuring is tested.ZOC33 electric pressure scaner is wind tunnel pressure measuring capital equipment, when extensive manometric test carried out by return circuit wind tunnel of remaining silent, sensor is many, pipeline is intensive, cause ZOC33 electric pressure scaner temperature too high, easily cause its air bag controlling working method damaged, make test data abnormal, affect test efficiency.Therefore be badly in need of the special cooling structure of a kind of ZOC33 electric pressure scaner, reduce ZOC33 electric pressure scaner spoilage, save time cost and cost of material.
Model utility content
The purpose of this utility model is the cooling structure providing a kind of manometric test electric pressure scaner, and it is rational in infrastructure, can the cooling of auxiliary electron pressure scanning valve.
For achieving the above object, the technical solution of the utility model designs a kind of cooling structure of manometric test electric pressure scaner, described electric pressure scaner comprises: the main casing of bottom opening, and for the rectangular metal base plate of closed main casing bottom opening;
The outer side surface of described base plate is provided with closed cuboid hollow cooling storehouse, and length direction and the floor length direction in this cooling storehouse are arranged in the same way;
Described cooling storehouse is provided with a pair for connecting the joint of exterior line, and this butt joint is divided into cooling length direction both sides, storehouse;
Inside, described cooling storehouse is also provided with the snakelike heat exchange tube of this butt joint through;
Described base plate is also provided with some installation through holes for assembling with main casing, it is outside that described installation through hole is positioned at cooling storehouse.
Preferably, the surface of described base plate is provided with the patina generated by anodization.
Preferably, the length, width and height of described base plate are: 126mm × 30mm × 6mm.
Preferably, described electric pressure scaner is ZOC33 electric pressure scaner.
Advantage of the present utility model and beneficial effect are: the cooling structure providing a kind of manometric test electric pressure scaner, and it is rational in infrastructure, can lower the temperature, to meet wind tunnel test requirement by auxiliary electron pressure scanning valve.Cooling-down effect of the present invention is good, avoids the too high problem causing the balloon rupture of its control working method of ZOC33 electric pressure scaner Yin Wendu in process of the test.Economic benefits are good, and use value is high.
Cooling arranges snakelike heat exchange tube in storehouse, snakelike heat exchange tube connects exterior line by the joint at its two ends, exterior line can continue transporting low temperature nitrogen to snakelike heat exchange tube, and low temperature nitrogen circulates and reduces ZOC33 electric pressure scaner temperature by cooling storehouse, balloon rupture when avoiding its work.
Wind tunnel pressure measuring prepares, the factors such as model assembly, section, inner space and ZOC33 electric pressure scaner position need be considered, cooling structure can not impact it, therefore cooling structure of the present utility model manufactures with installation through hole (screw hole) according to the base plate size of ZOC33 electric pressure scaner self, and anodization is carried out on surface.Cooling structure reference dimension length, width and height are: 126mm × 30mm × 6mm, directly cater to ZOC33 electric pressure scaner, exterior line (gas circuit) adopts consistent with existing pressure-measuring pipe, cooling process can be carried out to multiple ZOC33 electric pressure scaner by multiple-pass joint link simultaneously, can not impact for the installation of ZOC33 electric pressure scaner in pressure measuring model.
Cooling countermeasure is mainly divided into water-cooled and air-cooled two kinds.Cooling processing mode can not bring impact by stream field itself, therefore considers the scanning valve base plate of design with cavity, utilizes the flowing of liquid or gas to reach cooling object.Leak if liquid occurs the cooling countermeasure of water-cooled, easily cause ZOC33 electric pressure scaner to damage, and the sub-gas of the double source selecting nitrogen mainly to consider that it is almost inertia, chemical property pole torpescence, not easily expands with heat and contract with cold, and amplitude of deformation is little, and low price.
Cooling structure agrees with ZOC33 electric pressure scaner, can not bring impact to its installation in model; Good cooling effect, carry out 1000 inflation/deflation tests to ZOC electric pressure scaner, in the past because the too high air bag breakage of temperature reaches 26 times, after adopting cooling structure, breakage was only 2 times.
