With the development of phased array radar technology, TR components have tended to be miniaturized, multi-functional, high-power, etc. Usually, a phased array radar contains dozens or even hundreds or thousands of TR components, which undoubtedly puts higher requirements on the production and delivery of TR components.

During this period, if the TR component cannot be effectively cooled, the TR component is likely to be permanently burned out due to overheating. To avoid damage to the TR component, it can only be tested after the temperature of the TR component returns to the safe temperature range, and the test efficiency is low.

[0029] Embodiment:

[0030] As Figure 1 and Figure 2 shown, a test fixture for a TR component includes a liquid cooling plate 1 and a control board 2;

[0031] The liquid cooling plate 1 is provided with a test slot for placing the TR component 14 and a liquid cooling pipe 3 for cooling the TR component 14. The liquid cooling pipe 3 includes a coiled pipe section corresponding to the heat generating part of the TR component 14.

[0032] The control board 2 is arranged on the liquid cooling plate 1. When testing, the control board 2 is used to control the TR component 14.

[0033] The test fixture for the TR component reserves an installation space for the liquid cooling pipe 3 through the liquid cooling plate 1 and dissipates heat from the TR component 14 by means of liquid cooling. It can not only effectively improve the heat dissipation effect, but also avoid damage to the TR component 14 during long-term high-temperature testing. Therefore, the test fixture for the TR component can effectively improve the test efficiency. And for the situation where the local heat generation of the TR component 14 is large, the liquid cooling pipe 3 further increases the heat dissipation efficiency through the setting of the coiled pipe section, dissipates heat in time, and avoids damage to the TR component 14.

[0034] Furthermore, the TR component test fixture is also provided with a control board 2, which is used to provide power supply signals and control signals for the test of the TR component 14, realizing automated intelligent testing and reducing manual participation. At the same time, the control board 2 is also arranged on the liquid cooling plate 1, and the heat dissipated when the control board 2 works can also be taken away by the liquid cooling channel, avoiding overheating.

[0035] During operation, the staff installs the TR component 14 in the test slot and then connects the cables for signal transmission. The staff can then start the test through a control device such as a computer. After the test is completed, the cables are removed, the tested TR component 14 is taken off, and the TR component 14 to be tested is replaced to prepare for the next test.

[0036] In a possible implementation, a surrounding platform 4 that protrudes upward and has an opening is provided on the top surface of the liquid cooling plate 1. The top surface of the liquid cooling plate 1 is divided by the surrounding platform 4 into a test area inside the surrounding platform 4 and an additional area outside the surrounding platform 4. A detachable top plate 5 is provided on the surrounding platform 4. The test area, the surrounding platform 4, and the top plate 5 enclose a one-way open test slot, and the additional area and the surrounding platform 4 form a stepped surface for fixing.

[0037] Based on the above design, when placing and removing the TR component 14, the top plate 5 is removed from the surrounding platform 4 to make the top surface of the test slot open, facilitating the placement and removal of the TR component 14. The surrounding platform 4 not only encloses the test area but also forms a stepped surface together with the additional area, thus facilitating the connection of the TR component test fixture to other test equipment and further carrying out different tests, effectively expanding the usage range of the TR component test fixture and having better practicability.

[0038] For the liquid cooling pipe 3, the upward surrounding platform 4 ensures the thickness of the liquid cooling plate 1, and the design of the liquid cooling pipe 3, especially the coiled pipe section, is more flexible, which helps to ensure the heat dissipation effect of the liquid cooling pipe 3.

[0039] It is easy to understand that the height of the upward extension of the surrounding platform 4 is determined according to the thickness of the tested TR component 14.

[0040] Alternatively, the test area is configured as a downwardly concave trough structure, and the TR component 14 is inserted into the liquid cooling plate 1. At this time, a test slot adapted to the TR component 14 is also formed on the liquid cooling plate 1. However, when the liquid cooling plate 1 is configured in this scheme, the thickness of the liquid cooling plate 1 becomes thinner, the design of the liquid cooling pipe 3 is limited, and a stepped surface cannot be formed, resulting in a worse subsequent connection effect. Therefore, it is preferred that the liquid cooling plate 1 forms a test slot through the surrounding platform 4.

[0041] As can be seen from the background art, the existing fixture has low test efficiency, which is not only due to the heat dissipation problem, but also related to the fact that the existing fixture only tests one TR component 14 at a time. Therefore, in a possible implementation, the test slot is divided into several sub-areas, each sub-area is used to connect a TR component 14, and correspondingly, several first positioning posts are provided in each sub-area, and several coil pipe sections are provided in the coil pipe section and are arranged in one-to-one correspondence with the sub-areas.

[0042] Based on the above design scheme, by partitioning the test slot, the number of measurements per time is increased, thereby improving the test efficiency. At the same time, the first positioning posts are arranged in the sub-areas to realize the positioning, installation and fixation of the TR component 14, ensure the accuracy of the installation of the TR component 14, and reduce the probability of disturbance of the TR component 14 during the test. Correspondingly, multiple coil pipe sections are also arranged in the coil pipe section of the liquid cooling pipe 3 to ensure the heat dissipation effect of each TR component 14.

[0043] Optionally, as Figure 1 shown, the four sub-areas are arranged in sequence along the length direction of the liquid cooling plate 1. Correspondingly, the first positioning posts, the second positioning posts and the relevant cables are also divided into four groups and are respectively connected to the corresponding TR components 14. It is easy to understand that those skilled in the art can arbitrarily increase or decrease the number of sub-areas, which will not be elaborated here.

[0044] Based on this, compared with the existing fixture, the TR component test fixture is integrated with the TR component 14, so as to be integrally transferred to different types of tests, such as high / low temperature test, vibration test, temperature-humidity-altitude test, etc. Connection and fixation can be achieved through the stepped surface, without additional connection of relevant equipment, and the test cost is lower. During the test process, the TR component test fixture is simple to operate, has high test efficiency, multiple test functions, low test cost, and better practicability.

[0045] For the TR component 14, during the test, the TR component 14 not only needs to be physically connected to the TR component test fixture, but also needs to be electrically connected to the TR component test fixture. Specifically, in a possible implementation, a connection slot located in the test area is provided on the liquid cooling plate 1, a detachable connection plate 6 is provided on the connection slot, and several second positioning posts and several installation areas are provided on the connection plate 6. The second positioning posts are distributed in the sub-areas and are used to fix the TR component 14, and the installation areas are arranged in one-to-one correspondence with the sub-areas, and connectors for electrical connection are provided on each installation area.

[0046] Based on the above design scheme, the connection slot not only provides an installation space for the connection plate 6, but also reserves an accommodation space for the setting of the remaining cables. The connection plate 6 is installed on the liquid cooling plate 1 by a detachable connection method such as screws. On the one hand, the connection plate 6 cooperates with the first positioning posts through the second positioning posts to increase the number of fixing points of the TR component 14, and on the other hand, it provides connectors for the TR component 14 through the installation areas to realize electrical connection.

[0047] It is easily understandable that, according to the type of the TR component 14, those skilled in the art can flexibly select the respective numbers of the first positioning post and the second positioning post, and set the first positioning post and the second positioning post at appropriate positions on the sub-region.

[0048] Optionally, the connector includes a low-frequency connector 7 and a first radio-frequency connector 8. The low-frequency connector 7 is used to connect the control board 2 and the TR component 14, and the first radio-frequency connector 8 is used to connect the test system and the TR component 14, and the first radio-frequency connector 8 is selected as a floating connector. Based on the above design solution, one end of the low-frequency connector 7 can be connected to the TR component 14 in a butt-joint manner, and the other end of the low-frequency connector 7 is connected to the control board 2, so as to provide a power supply signal and a control signal for the TR component 14 through the low-frequency connector 7.

[0049] Since the diameter of the radio-frequency cable is small, the diameter of the corresponding connector is also small. During the test process, especially during the vibration test, the connector is prone to damage, which not only reduces the test success rate, but also slows down the test efficiency and increases the test cost. Therefore, the first radio-frequency connector 8 is preferably a floating connector with a reserved margin, which can not only avoid damage during connection, but also reduce the probability of damage to the joint of the first radio-frequency connector 8 during the vibration test.

[0050] It is easily understandable that any suitable existing equipment can be selected for the test system, which will not be elaborated here.

[0051] Since the TR component 14 has multiple channels, and due to the different working states of the TR component 14, the same channel can be used for signal input or signal output. Then, in a possible implementation manner, a second radio-frequency connector 10 for connecting the test system and the TR component 14 is provided on the top plate 5. The second radio-frequency connector 10 is selected as a floating connector, and a wire clamp for fixing the test cable is provided on the top plate 5.

[0052] Based on the above design solution, on the one hand, the number of radio-frequency connectors is increased to facilitate meeting the test requirements of different types of TR components 14, and on the other hand, the cables can be connected in different directions, which is more convenient for connection and avoids the cables being too concentrated. It is easily understandable that the first radio-frequency connector 8 and the second radio-frequency connector 10 are preferably of the same type.

[0053] It is easily understandable that, according to the type of the TR component 14, those skilled in the art can flexibly select the TR component test fixture corresponding to the number of radio-frequency connectors. Correspondingly, the TR component test fixture is set in multiple models for testers to select, so as to improve the test success rate and efficiency.

[0054] In addition, the cable is fixed by a cable clamp to avoid entanglement of cables. In tests that require movement of the test fixture for the TR component, such as vibration tests, the probability of damage to related components such as cables and connectors is effectively reduced, and the success rate and efficiency of the test are improved.

[0055] Preferably, a protective pad 9 is provided on the bottom surface of the top plate 5. Based on this, the appearance of the TR component 14 is protected from damage by the protective pad 9, especially during vibration tests, ensuring the integrity of the appearance of the TR component 14.

[0056] In a possible implementation, the two ends of the liquid cooling pipe 3 are respectively configured as a liquid inlet 301 and a liquid outlet 302, and the liquid cooling pipe 3 is connected to the liquid cooling system through the liquid inlet 301 and the liquid outlet 302. Based on the above design, any suitable commercially available model can be selected for the liquid cooling system. Connectors for connection are provided at the liquid inlet 301 and the liquid outlet 302 respectively, and the connectors are detachably arranged on the liquid cooling plate 1 to improve the convenience and stability of connection. Further, according to the different TR components 14 to be tested, the position and shape of the coiled pipe section are flexibly changed to achieve the best heat dissipation effect.

[0057] In a possible implementation, a power supply interface 11 and a control interface 12 are provided on the liquid cooling plate 1, and the power supply interface 11 and the control interface 12 are connected to the outside through an adapter. Based on the above design, any suitable existing models can be selected for the power supply interface 11, the control interface 12, and the adapter, and the present utility model does not make any restrictions on this.

[0058] Optionally, as Figure 2 shown, an opening is provided on the side surface of the liquid cooling plate 1 to facilitate the setting of the adapter, so that the power supply interface 11 and the control interface 12 are respectively connected to the outside through the adapter.

[0059] In a possible implementation, a control switch electrically connected to the TR component 14 is provided on the control board 2. When there are several TR components 14, several control switches are provided and are arranged in one-to-one correspondence with the control signals required by the TR component 14. Based on the above design, the number of control switches is the same as that of the TR components 14, so as to correspond one-to-one and transmit signals to the corresponding TR components 14 to achieve automated testing.

[0060] It is easy to understand that any suitable existing switch can be selected as the control switch. The control board 2 is also provided with functional modules such as a power supply, a processor, and an isolation driver to complete the function of the control board 2 for testing the TR component 14. Optionally, in a practical and feasible solution, the power supply selects a power control circuit, the processor selects an FPGA (Field Programmable Gate Array), the control switch selects a CMOS (Complementary Metal Oxide Semiconductor) switch, and the control board 2 is also provided with an isolation driver to achieve electrical isolation between circuits and improve the safety of the control board 2.

[0061] Optionally, as Figure 2 shown, the bottom surface of the liquid cooling plate 1 is provided with a mounting groove adapted to the control board 2 and a bottom plate 13 for closing the mounting groove. When the control board 2 is arranged in the mounting groove, the bottom plate 13 is fixed on the bottom surface of the liquid cooling plate 1 and closes the mounting groove to protect the control board 2.

[0062] Based on the above TR component test fixture, a TR component test system is introduced in this embodiment. The TR component test system includes the above-mentioned TR component test fixture.

[0063] Based on this, according to different test experiments, the TR component test system selects any suitable functional module, connects the TR component test fixture and completes the corresponding test, and the functional module can select any suitable existing device, with a wide selection range and good practicability.

[0064] The above specific embodiments have further detailed the purpose, technical solution and beneficial effects of the present invention. It should be understood that the above is only the specific embodiment of the present invention and is not used to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
