[0031] The following is combined with Figures 1-4 This application is described in further detail.

[0032] The embodiments of the present application disclose a water-cooled adjustable testing tool.

[0033] A water-cooled, adjustable test fixture is used to secure a TR assembly 6, with several grooves defined on its sidewalls. The fixture comprises a cooling base 1 and a slide bed 2. The cooling base 1 incorporates a cooling unit 3, while the slide bed 2 slidably engages the cooling base 1. The slide bed 2 is secured to the cooling base 1 via a locking unit 4. A clamping unit 5 is provided on the slide bed 2, which presses the TR assembly 6 against the slide bed 2.

[0034] Before testing the TR assembly 6, different models of slider beds 2 are selected based on the size of the TR assembly 6. The slider beds 2 are placed on the cooling seat 1 and locked to the cooling seat 1 using the locking unit 4. A heat-conducting medium is then filled between the slider beds 2 and the cooling seat 1. The TR assembly 6 is then placed on the slider bed 2 and pressed against the slider bed 2 using the pressing unit 5. During the TR assembly 6 test, the large amount of heat generated by the TR assembly 6 is quickly transferred to the slider bed 2 and then to the cooling seat 1 via the heat-conducting medium. The heat is then dissipated by the cooling unit 3 inside the cooling seat 1, thereby reducing the possibility of heat accumulation in the TR assembly 6 and facilitating heat dissipation from the TR assembly 6.

[0035] The cooling base 1 is generally rectangular in shape, with a placement slot defined at its bottom, the slot of which is secured by screws. The cooling unit 3 is a liquid cooling tube placed within the placement slot, in contact with the inner wall of the placement slot. Both the liquid inlet and outlet of the liquid cooling tube extend through the slot wall. Coolant flows through the liquid cooling tube, exchanging heat and cooling the TR assembly 6. In this embodiment, the coolant is water. To maximize the contact surface between the liquid cooling tube and the slot wall, the liquid cooling tube is arranged in a serpentine pattern.

[0036] A slide groove 11 is provided on the top of the cooling seat 1 , and the slide bed 2 is placed inside the slide groove 11 . The slide bed 2 and the slide groove 11 are slidably matched, and the slide bed 2 is preliminarily positioned by the inner wall of the slide groove 11 .

[0037] A guide groove 13 is provided at the bottom of the inner wall of the slide groove 11 along the length direction of the slide groove 11, and a guide rail 22 is integrally formed at the bottom of the slide bed 2 to slide with the guide groove 13. When the slide bed 2 moves, the inner wall of the guide groove 13 guides the slide bed 2 through the guide rail 22.

[0038] The slider bed 2 is provided with a number of mounting holes 21. In the embodiment of the present application, the heat-conducting medium is thermal grease, which can be injected between the slider bed 2 and the cooling seat 1 through the mounting holes 21, thereby increasing the contact area between the heat-conducting medium, the slider bed 2 and the cooling seat 1, and improving the distribution uniformity of the heat-conducting medium.

[0039] At the same time, the heat-conducting medium is located between the slider bed 2 and the cooling seat 1 and also has a certain lubricity, which facilitates the sliding of the slider bed 2 on the cooling seat 1 .

[0040] In the embodiment of the present application, the TR assembly 6 is provided with three grooves, and the pressing unit 5 is also provided with three grooves, and the grooves of the pressing unit 5 and the TR assembly 6 are adapted to each other.

[0041] The pressing unit 5 includes a mounting block 51 , a pressing head 52 and a first bolt 53 .

[0042] The mounting block 51 is located on the top of the slider bed 2, and the mounting block 51 fits closely to the slider bed 2. The pressing head 52 is located on a side of the mounting block 51 close to the TR assembly 6, and the pressing head 52 and the mounting block 51 are integrally formed.

[0043] To facilitate the compression of the TR assembly 6 by the compression head 52, a sloped surface is provided at the bottom of the compression head 52, near the TR assembly 6. The distance between the sloped surface and the slider bed 2 gradually increases as the mounting block 51 extends toward the TR assembly 6. A first bolt 53 penetrates the mounting block 51 and is threadedly engaged with the adjacent mounting hole 21. The bolt head of the first bolt 53 presses the mounting block 51 against the slider bed 2.

[0044] When tightening the TR assembly 6, the tightening head 52 is gradually inserted into the groove of the TR assembly 6, and the bottom inclined surface of the tightening head 52 contacts the inner wall of the groove of the TR assembly 6 to adapt to the grooves of different depths of the TR assembly 6. Then, the first bolt 53 is passed through the mounting block 51, and the first bolt 53 is threadedly connected to the mounting hole 21, and the threaded head of the first bolt 53 presses the mounting block 51 onto the slide bed 2.

[0045] In order to facilitate the threaded connection between the first bolt 53 and the mounting hole 21, an adjustment groove 511 is opened on the top of the mounting block 51. The adjustment groove 511 passes through the mounting block 51. The screw of the first bolt 53 is placed inside the adjustment groove 511 and slides with the adjustment groove 511 to increase the range of motion of the first bolt 53.

[0046] Several groups of connecting holes 12 are provided on the two opposite vertical groove walls of the slide groove 11 along the length direction of the slide groove 11. In the application embodiment, four groups of connecting holes 12 are provided on each vertical side wall of the slide groove 11, and each group of connecting holes 12 includes two connecting holes 12.

[0047] There are a plurality of locking units 4, each of which is matched with each group of connecting holes 12. The specific number of locking units 4 can be adjusted according to the size of the slider bed 2. In the embodiment of the present application, there are six locking units 4.

[0048] Each locking unit 4 includes a locking block 41 and a second bolt 42 .

[0049] A locking rod 411 is integrally formed at the bottom of the locking block 41. The locking block 41 and the locking rod 411 are arranged in a T shape as a whole, and two locking holes 412 are opened on the locking block 41. The two locking holes 412 correspond to the two connecting holes 12 of each group of connecting holes 12 one by one.

[0050] There are two second bolts 42 , and the two second bolts 42 correspond to the two locking holes 412 in a one-to-one manner. The second bolts 42 are threadedly connected to the connecting holes 12 .

[0051] When fixing the slider bed 2 to the cooling seat 1, the locking rod 411 is inserted into the adjacent mounting hole 21, and then the second bolt 42 is rotated so that the second bolt 42 passes through the connecting hole 12 and the locking hole 412. Thus, the slider bed 2 is fixed to the cooling seat 1, and the convenience of fixing the slider bed 2 to the cooling seat 1 is improved.

[0052] The implementation principle of a water-cooled adjustable test fixture in the embodiment of the present application is as follows: before testing the TR assembly 6, a suitable slider bed 2 is selected according to the size of the TR assembly 6, and the slider bed 2 is slidably matched with the cooling seat 1 through the guide rail 22. Then, the locking rod 411 is inserted into the mounting hole 21, and the second bolt 42 is threadedly connected to the connecting hole 12, so that the second bolt 42 passes through the locking hole 412, completing the installation of the slider bed 2. Then, the clamping block is placed inside the groove of the TR assembly 6, and the first bolt 53 is threadedly connected to the adjacent mounting hole 21 through the adjustment waist groove 511, so that the TR assembly 6 is pressed against the slider bed 2 through the clamping block, completing the fixation of the TR assembly 6. When testing the TR assembly 6, the heat dissipated by the TR assembly 6 is quickly transferred from the slider bed 2 to the thermal grease, and then transferred to the cooling seat 1 through the thermal grease for heat dissipation, thereby reducing the temperature of the TR assembly 6.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
