Description

Technical Field

[0001] The utility model belongs to the technical field of wind tunnel test model equipment, and more specifically, relates to a water-cooled model jacket used in high-temperature flow fields. Background Art

[0002] When conducting wind tunnel tests in high-temperature flow fields, relevant model jackets are needed to fix the test pieces. However, the temperature in high-temperature flow fields is very high, usually reaching 5000~10000K, and the model and test pieces will generate a lot of heat. If the heat cannot be dissipated in a timely and effective manner, it will cause equipment damage, test failure, and even safety accidents. Therefore, in order to ensure the smooth progress of wind tunnel tests, it is necessary to design water cooling for the model jacket. However, in current high-temperature wind tunnel tests, there is a lack of model jackets that can achieve a fluid water cooling structure. Utility Model Content

[0023] Figure 1 The utility model shows a water-cooled model jacket for high-temperature flow fields, comprising a truncated cone-shaped structure 1 and a shell 2 with a conical outer surface, a predetermined gap is provided between the structure 1 and the shell 2 to construct a cavity 3 for accommodating a cooling medium therebetween, and a water inlet 4 and a water outlet 5 communicating with the interior of the cavity 3 are symmetrically arranged at the bottom of the structure 1;

[0024] The water barrier strips 8 are symmetrically arranged on the surface of the structural member 1, and the water barrier strips 8 are arranged along the generatrix direction of the structural member 1 to separate the cavity 3 in space to obtain a water inlet cavity 31 and a water outlet cavity 32 that match the water inlet 4 and the water outlet 5;

[0025] The front ends of the structural member 1 and the housing 2 are provided with matching extension parts 6 , and the extension parts 6 have an annular cavity 7 communicating with the water inlet cavity 31 and the water outlet cavity 32 after being buckled.

[0026] Working principle:

[0027] During operation, the jacket clamps the model part, and a cavity 3 is formed by a predetermined gap between the structural part 1 and the outer conical shell 2. The external pipeline 10 connects the water inlet 4 and the water outlet 5. The cooling medium such as water or other liquid transported by one end of the external pipeline 10 enters through the water inlet 4 and then flows out through the external pipeline 10 at the water outlet 5, so that the cooling medium flows in the cavity 3, and the temperature of the high-temperature flow field on the model part is reduced by heat exchange. The water barrier 8 arranged along the busbar direction of the structural part 1 divides the cavity 3 into a water inlet cavity 31 and a water outlet cavity 32 in space. This design ensures that the cooling medium fully absorbs heat in the water inlet cavity 31 before entering the water outlet cavity 32, thereby improving the heat exchange efficiency. The front ends of the structural part 1 and the shell 2 are provided with matching extensions 6. When these extensions 6 are buckled, an annular cavity 7 connected to the water inlet cavity 31 and the water outlet cavity 32 is formed. The annular cavity 7 is in contact with the model part, ensuring that the heat on the model part can be quickly transferred to the jacket. The utility model divides the area by the water barrier strip 8, which can ensure that the cooling medium forms an effective circulation flow between the water inlet cavity 31 and the water outlet cavity 32. This flow mode can maximize the utilization rate of the cooling medium, thereby achieving effective cooling of the model part.

[0028] In the above scheme, a plurality of diverter bars 9 are arranged on the surface of the structural member 1, and the diverter bars 9 are arranged along the busbar direction of the structural member 1, and the length of the diverter bars 9 is less than the length of the water barrier bar 8. With this technical scheme, the diverter bars 9 divide the cooling medium in the water inlet chamber 31 and the water outlet chamber 32 more finely to form a plurality of small cooling channels. This helps the cooling medium to be more evenly distributed in the cavity 3, and to perform more effective heat exchange with the high-temperature flow field. At the same time, due to the presence of the diverter bars 9, the cooling medium will contact the inner wall of the structural member 1 and the shell 2 multiple times during the flow process, thereby increasing the area of ​​heat exchange. This helps to transfer heat from the high-temperature flow field to the cooling medium more quickly.

[0029] In the above scheme, the diverter baffle 9 has at least two lengths, and the diverter baffles 9 of different lengths are staggered in space. With this technical solution, since the diverter baffles 9 have different lengths and are staggered in space, the cooling medium will be divided into multiple streams with different paths and flow rates after entering the water inlet chamber 31. This multi-level diversion helps to ensure that the cooling medium can cover a wider area and conduct more sufficient heat exchange with the high-temperature flow field. Diverter baffles 9 of different lengths can form different flow channel widths and lengths, and these different flow channels have different effects on the heat exchange between the cooling medium and the high-temperature flow field. By rationally designing the length and layout of the diverter baffles 9, the heat exchange efficiency can be optimized to ensure that heat can be transferred more quickly and evenly.

[0030] In the above scheme, after the structural member 1 and the shell 2 are buckled together, the structural member 1 and the shell 2 are connected into an integrated structure by setting a plug weld at the water barrier 8 and the diverter baffle 9. With this technical solution, the plug weld is a welding point set at the position of the water barrier 8 and the diverter baffle 9, which tightly connects the structural member 1 and the shell 2 together to form an integral structure. This design ensures the stability and sealing between the structural member 1 and the shell 2. At the same time, it enables the jacket to withstand 4MPa of cooling water. Increasing the pressure of the cooling water also increases the water flow rate and improves the efficiency of heat exchange.

[0031] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
