Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of surface heat flow and pressure measurement of a model in a high-temperature airflow field, and in particular to a water-cooled integrated heat flow and pressure measurement device. Background Art
[0002] Currently, with the development of spacecraft, the requirements for ground-based thermal protection testing are becoming increasingly stringent. Ground-based thermal protection testing is required to simulate the flight conditions of hypersonic aircraft as accurately as possible. One of the commonly used devices for ground-based thermal protection testing is an arc heater, which heats the gas through a high-power electric arc to produce a high-temperature, high-speed airflow. A heat flow and pressure measuring device is then used to measure the surface heat flux and pressure of the model in the high-temperature airflow field. Currently, the commonly used heat flow and pressure measuring devices are transient measurement devices, with heating times of only a few seconds. However, current full-orbit simulation tests of hypersonic aircraft urgently require the ability to measure the distribution of heat flux and pressure on the model surface under long-term, full-orbit conditions. To achieve this goal, the first issue to be addressed is cooling.
[0003] In addition, it is well known that the more measuring points there are per unit area, the more accurate the measurement data. However, due to the fact that the integrated heat and pressure measuring plates and each heat flow sensor base of the existing testing device are supplied with and discharged water separately, the number of measuring points arranged per unit area is limited and difficult to break through. In addition, there are many water supply and outlet pipelines, and the installation and maintenance costs are high and the efficiency is low. Summary of the Invention

[0083] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0084] Example 1
[0085] like Figures 1 to 15 As shown, the base of the water-cooled integrated heat flow and pressure measuring device provided by the embodiment of the present invention includes a heat and pressure measuring plate 1 and a plurality of sensor seats 2. The plurality of sensor seats 2 are installed on the heat and pressure measuring plate 1. The heat and pressure measuring plate 1 and the sensor seats 2 are respectively provided with cooling structures. The cooling structures of the two cooperate with each other to form a set of cooling structures, which greatly reduces the installation and maintenance costs, improves the installation and maintenance efficiency, and can also reduce the volume of the sensor seat 2, increase the upper limit of the sensor arrangement density, and thus improve the test accuracy.
[0086] Specifically, see Figures 2 to 4 、 Figure 6 and Figures 9 to 11 As shown, a plurality of mounting holes 11 are spaced apart on the heat and pressure measuring plate 1. The mounting holes 11 pass through the heat and pressure measuring plate 1. Cooling channels are provided in the areas where the mounting holes 11 are distributed inside the heat and pressure measuring plate 1. The cooling channels include a shunt channel 12, a confluence channel 13, a shunt branch 14 and a confluence branch 15. Each mounting hole 11 is connected to the shunt channel 12 through a shunt branch 14 and to the confluence channel 13 through a confluence branch 15. A water inlet 16 and a water outlet 17 are provided at the end of the heat and pressure measuring plate 1 away from the heated surface. The water inlet 16 is connected to the shunt channel 12, and the water outlet 17 is connected to the confluence channel 13. A plurality of pressure measuring holes 18 for installing pressure measuring tubes are spaced apart on the heat and pressure measuring plate 1.
[0087] Each sensor seat 2 is provided with a wire hole 21 passing through the sensor seat 2, and the interior of the sensor seat 2 is also provided with an annular cavity 22 surrounding the wire hole 21. The outer wall of the sensor seat 2 is provided with a water inlet hole 23 and a water outlet hole 24 connected to the annular cavity 22. The sensor seat 2 is inserted into the mounting hole 11, and the diversion branch 14 is connected to the water inlet hole 23, and the water outlet hole 24 is connected to the converging branch 15.
[0088] When using, see Figure 8As shown, the water inlet 16 is connected to the water inlet pipe (not shown in the figure). The water outlet 17 is connected to the water outlet pipe (not shown in the figure). A sensor seat 2 is installed in each mounting hole 11. The cooling water (liquid) is injected into the diverter channel 12 from the water inlet 16 and then flows into the annular cavity 22 through the diverter branch 14 and the water inlet 23. Then it flows out of the confluence channel 13 through the water outlet 24 and the confluence branch 15, and finally flows out from the water outlet 17 and the water outlet pipe. This cycle realizes the cooling of the base. Compared with the prior art, the heat and pressure measuring plate and each sensor seat are separately connected to the water inlet and outlet pipes. After the connection, each sensor seat is installed on the heat and pressure measuring plate through a flange structure. This embodiment features a newly designed cooling channel structure, redesigning the structures of both the heat and pressure measuring plate 1 and the sensor base 2. The sensor base 2 itself serves as part of the cooling channel, allowing both to share a common set of water inlet and outlet pipes. This eliminates the need for additional water inlet and outlet connections to the sensor base, significantly reducing the number of inlet and outlet pipes and the risk of leaks from numerous pipe joints. This enables the use of high-pressure water cooling, improving cooling efficiency and enabling long-term steady-state measurement of high heat flux. Furthermore, this improves sensor installation efficiency while reducing sensor size, enabling the placement of more sensors per unit area and thus enhancing the measurement accuracy of the measuring device.
[0089] In one example, see Figure 6 As shown, the flow diversion channel 12 includes a transversely arranged main flow diversion channel 121 and a plurality of longitudinally arranged branch flow diversion channels 122. One end of each branch flow diversion channel 122 is connected to the main flow diversion channel 121, and the plurality of branch flow diversion channels 122 are spaced apart. The flow confluence channel 13 includes a transversely arranged main flow confluence channel 131 and a plurality of longitudinally arranged branch flow confluence channels 132. One end of each branch flow confluence channel 132 is connected to the main flow confluence channel 131, and the plurality of branch flow confluence channels 132 are spaced apart. The main diverter channel 121 and the main converging channel 131 are arranged in parallel and spaced apart. Multiple branch diverter channels 122 and multiple branch converging channels 132 are staggered. Between adjacent branch diverter channels 122 and converging channels 132, a row of mounting holes 11 is distributed along the length of each branch diverter channel 122 and converging channel 132. Each mounting hole 11 is connected to an adjacent branch diverter channel 122 and converging channel 132 via a diverter branch 14 and a converging branch 15. The water inlet 16 is directly connected to the main diverter channel 121, and the water outlet 17 is directly connected to the main converging channel 131.
[0090] In a specific example, the heat and pressure measuring plate 1 is made of seamless Tu2 copper plate and measures 220mm x 200mm x 15mm. Three branch flow channels 122 and three branch converging channels 132 are arranged on the heat and pressure measuring plate 1, with 25 mounting holes for steady-state heat flux sensors arranged thereon. The three branch flow channels 122 and three branch converging channels 132 are staggered, with a row of mounting holes 11 provided between each pair of adjacent branch converging channels 132 and branch flow channels 122. Each row of mounting holes 11 has five mounting holes, for a total of 25 mounting holes 11, allowing for the placement of 25 heat flux sensors. Two water inlets 16, or welding points for the water inlet pipes, are directly and spaced apart on the main flow diversion channel 121. Two water outlets 17, or welding points for the water outlet pipes, are directly and spaced apart on the main converging channel 131. Twenty pressure measuring holes 18 are distributed between adjacent mounting holes 11. The sensor base 2 is made of steel by 3D printing and is tightly installed in the mounting hole 11 to form the base of the heat and pressure measuring device.
[0091] In order to improve the sealing performance, to prevent the cooling water from flowing out or the hot air from flowing from the heated surface through the heat and pressure measuring plate 1 to the other side, in one example, see Figure 4 、 Figure 13 and Figure 14 As shown, the outer periphery of the sensor base 2 is provided with a sealing groove 26, and a sealing ring 261 is disposed within each sealing groove 26. More preferably, the outer periphery of the sensor base 2 is provided with two sealing grooves 26 spaced axially along the wire hole 21, with the water inlet 23 and the water outlet 24 both located between the two sealing grooves 26. In another example, the water inlet 23 and the water outlet 24 are coaxially arranged.
[0092] To further improve installation efficiency and accuracy, see Figure 1 、 Figures 10 to 12 As shown, an anti-foolproof plane 111 is provided on the inner wall of one end of the mounting hole 11, and a cutout plane 25 is provided at a position of the sensor holder 2 corresponding to the anti-foolproof plane 11. The anti-foolproof plane 111 forms an asymmetric structure located within the mounting hole 11, which limits the circumferential position of the sensor holder 2 when inserted, that is, limits the sensor holder 2 to be inserted only at a set relative position. When the sensor holder 2 is installed in place, the cutout plane 25 is parallel and tightly attached to the anti-foolproof plane 111.
[0093] To further improve installation efficiency and accuracy, see Figure 1 、 Figures 10 to 15As shown, mounting hole 11, located at one end of the heated surface of the heat and pressure measuring plate 1, is provided with an annular protrusion 112 extending toward the center of mounting hole 11. Anti-fouling surface 111 is located on the inner side of annular protrusion 112. Sensor base 2 is divided into three sections along the axial direction of wire hole 21: a limiting section 27, a mounting section 28, and a lead section 29. The diameter of limiting section 27 is smaller than that of mounting section 28, and the outer circumference of limiting section 27 matches the inner shape of annular protrusion 112. The end of mounting section 28 abuts against annular protrusion 112 in the axial direction of mounting hole 11, thus limiting the axial position of sensor base 2. The end face of limiting section 27, facing away from mounting section 28, is flush with the heated surface of heat and pressure measuring plate 1, thus limiting both the circumferential and axial positions of sensor base 2.
[0094] In order to improve the reliability of the fixation of the sensor base 2 and prevent the sensor base 2 from moving when high-pressure water is supplied, based on the example with the annular protrusion 112, see Figures 13 to 15 As shown, one end of the mounting section 28 connected to the lead section 29 is flush with the surface of the heat and pressure measuring plate 1, and the lead section 29 extends out of the heat and pressure measuring plate 1. The diameter of the lead section 29 is smaller than the diameter of the mounting section 28. Figure 16 and Figure 17 As shown, on the end surface of the heat and pressure measuring plate 1 facing away from the heated surface, a threaded blind hole 19 is provided around each mounting hole 11. Each mounting hole 11 is also provided with a corresponding fixing plate 3. The fixing plate 3 has a fixing hole at one end and a sleeve hole at the other end. The sleeve hole has a diameter larger than that of the lead segment 29 and smaller than that of the mounting segment 28. The sleeve hole is sleeved over the lead segment 29 and pressed against the mounting segment 28. Screws 4 are passed through the fixing holes and connected to the threaded blind hole 19 to tighten the fixing plate 3. The fixing plate 3 compresses the sensor base 2 and cooperates with the annular protrusion 112 to achieve axial positioning of the sensor base 2, improving the securement of the sensor base 2. In embodiments having annular protrusion 112, with the anti-foolproofing flat surface 111 located inside the annular protrusion 112, and with the fixing plate 3, the annular protrusion 112, the fixing plate 3, the anti-foolproofing flat surface 111, and the cutout flat surface 25 cooperate to improve both installation efficiency and accuracy and securement of the sensor base 2.
[0095] It should be noted that the process holes 100 (see Figure 5 and Figure 8 As shown), it is a channel for the processing drill / tool to pass through and the material to be discharged, and it will be blocked after the processing is completed (see Figure 18 Of course, this is just one of the processing methods used in this embodiment. It can also be processed by 3D printing or two plates are processed separately and then connected to form an internal cooling channel, and then welded and fixed.
[0096] Example 2
[0097] like Figure 18 and Figure 19 As shown, this second embodiment provides a water-cooled integrated heat flow and pressure measurement device. The base can adopt any of the bases described in the first embodiment. A measuring portion is installed on each sensor seat 2, and a pressure measuring tube is installed at each pressure measuring hole 18, so that the device can be used to measure the heat flow and pressure on the model surface. In one example, the heat flow sensor is a circular foil heat flow sensor. The measuring portion includes a constantan sheet 5 and a signal line 6. One end of the signal line 6 is inserted into the wire hole 21. The constantan sheet 5 is located at the end of the signal line 6 and is in close contact with the signal line 6. The constantan sheet 5 is flush with the heated surface of the heat and pressure measuring plate 1. The structure and installation of the pressure measuring tube can be based on existing technologies and will not be described in detail here.
[0098] In summary, compared with the prior art, the heat measuring and pressure measuring plate and each sensor seat are individually connected to the water inlet and outlet pipes, and after the connection, each sensor seat is installed on the heat measuring and pressure measuring plate through a flange structure. The base of the water-cooled integrated heat flow and pressure measuring device provided by the present invention is newly designed with a cooling channel structure, and the structures of the heat measuring and pressure measuring plate and the sensor seat are redesigned. The sensor seat itself is part of the cooling channel, so that the two can share a set of water inlet and outlet pipes, and there is no need to connect the inlet and outlet pipes to the sensor seat separately, which greatly reduces the number of inlet and outlet pipes and reduces the risk of leakage of a large number of pipe joints. It can then use high-pressure water cooling to improve the cooling efficiency and achieve long-term steady-state measurement of high heat flow. In addition, it also improves the installation efficiency of the sensor, while reducing the volume, so that more sensors can be arranged per unit area, thereby improving the measurement accuracy of the measuring device.
[0099] Any details not described in detail in the present invention are common knowledge or prior art.
[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.

In the absence of a conflict of solutions, the various technical features mentioned in each embodiment can be combined in any manner to form other implementation methods that can be understood by those skilled in the art.
[0101] In addition, without departing from the scope of the present invention, the technical solutions described in the aforementioned embodiments may be modified, or some of the technical features thereof may be replaced by equivalents, without causing the essence of the corresponding technical solutions to depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
