Description

Technical Field

[0001] The present invention belongs to the technical field of aging test machines, and particularly relates to a liquid-cooled aging test machine and a method thereof. Background Art

[0002] Aging tests aim to simulate the working conditions of products under severe conditions such as long time and high load, so as to expose potential design defects, material flaws or manufacturing process problems in advance for timely improvement, thereby effectively reducing the failure rate of products during user use and enhancing the overall quality and market competitiveness of products.

[0003] Traditional aging test equipment mostly adopts air-cooled heat dissipation. However, with the rapid development of electronic technology, the power density of electronic devices has been continuously climbing, and the generated heat has increased significantly. Due to the limited heat dissipation efficiency of air-cooled heat dissipation, it is difficult to quickly and effectively dissipate heat when facing high heat flux density, resulting in too high temperature inside the test equipment. This will not only affect the accuracy and stability of test results, but also may damage the product under test due to overheating, thereby reducing the test efficiency and increasing the test cost.

[0004] In contrast, liquid-cooling technology has gradually become an ideal choice for solving the heat dissipation problem of high heat flux density due to its excellent heat dissipation performance. Liquids have a higher specific heat capacity and thermal conductivity than gases, and can absorb and carry away more heat.

[0005] However, the inventor found that when the existing liquid cooling is in use, due to the heat exchange method using heat exchange tubes, after long-term use, a certain amount of impurities are likely to accumulate on both the inner and outer surfaces of the heat exchange tubes. The increase in impurities not only easily causes blockage of the heat exchange tubes, but also the increase in impurities greatly affects the heat exchange efficiency, resulting in the problem of decreased heat exchange efficiency after the heat exchange tubes are used for a period of time.

[0006] Therefore, research and improvement are carried out on the existing structure and deficiencies, and a liquid-cooled aging test machine and a method thereof are provided, in order to achieve a more practical purpose. Summary of the Invention

[0012] Preferably, multiple heat dissipation grooves crossing the chute are provided on the heat dissipation plate. The width of the heat dissipation grooves does not affect the sliding of the first crescent pin.

[0013] Preferably, cleaning discs that can move back and forth and are used for cleaning the inner walls of the heat exchange tubes are provided inside the heat exchange tubes.

[0016] Preferably, a first water pump fixedly connected is provided in the heat exchange box.

A heat dissipation hole is further provided on one side of the test machine main body.

[0018] A test method for a liquid-cooled aging test machine, using the above-mentioned liquid-cooled aging test machine, includes the following steps:

[0019] S1 During the test, the coolant cooled by the heat exchanger in the heat exchange box is sent to the water inlet end of the liquid cooling tank. The cooled coolant is conveyed to the position that needs to be cooled in the test machine main body through the diversion of the liquid cooling tank for heat exchange and cooling, and then flows back to the heat exchanger through the drainage end of the liquid cooling tank for re-heat exchange and cooling, so that the coolant can circulate and cool down.

[0020] S2 When the coolant passes through the heat exchange tubes in the heat exchanger, control the rotation of the heat exchange tubes. Since the heat dissipation plates are in a reciprocating thread shape and multiple heat exchange tubes all pass through the same synchronous plate, the synchronous plate cannot rotate. Therefore, the rotation of the heat exchange tubes can realize the reciprocating movement of the synchronous plate on the heat exchange tubes through the first crescent pin, so that the first brush wire can reciprocate to clean the surface of the heat exchange tubes, preventing the accumulation of impurities on the surface of the heat exchange tubes and affecting the heat exchange efficiency of the heat exchange tubes.

[0021] Compared with the prior art, the present invention has the following technical effects:

[0022] The liquid cooling method effectively reduces the noise pollution during traditional air cooling, making the main body of the testing machine quieter during use. The design of the heat exchange tubes, heat dissipation plates, synchronous plates, and first crescent pins changes the original heat dissipation fins into reciprocating threaded shapes. This not only ensures the heat exchange efficiency of the heat exchange tubes but also enables the synchronous plates to reciprocate along the heat exchange tubes through the rotation of the heat exchange tubes and the cooperation of the first crescent pins according to the characteristics of the reciprocating threads. Then, in cooperation with the first brush filaments, during the heat exchange process of the heat exchange tubes, the first brush filaments can continuously and automatically clean the impurities on the surfaces of the heat exchange tubes and the heat dissipation plates, effectively preventing the accumulation of impurities on the surfaces of the heat exchange tubes and the heat dissipation plates, which may lead to poor heat exchange efficiency. At the same time, the reciprocating movement of the synchronous plates can make the heat exchange liquid in the heat exchange tank flow, fully increasing the contact probability between the heat exchange liquid and the heat exchange tubes and the heat dissipation plates, thereby improving the overall heat exchange efficiency;

[0023] The design of the cleaning disk and the second brush filaments can utilize the reciprocating movement of the cleaning disk and cooperate with the second brush filaments to achieve automatic cleaning inside the heat exchange tubes, effectively preventing the accumulation of impurities on the inner walls of the heat exchange tubes, which may affect the heat exchange efficiency.

[0024] The synchronous plates and the first brush filaments can clean the outer side walls of the heat exchange tubes, and the cleaning disk and the second brush filaments can clean the inner walls of the heat exchange tubes. Through the combination of internal and external cleaning, the accumulation of impurities on the inner and outer walls of the heat exchange tubes is effectively prevented, ensuring that the heat exchange tubes still have good heat exchange efficiency after being used for a period of time.

[0040] Example 1, please refer to Figure 1 、 Figure 2 and Figure 3 、 Figure 4 、 Figure 5 , a liquid-cooled aging tester, including a tester main body 1. A liquid-cooling tank is provided inside the tester main body 1, and a heat exchange box 2 is provided on one side of the tester main body 1. A heat exchanger 21 for adjusting the temperature of the coolant in the liquid-cooling tank is provided inside the heat exchange box 2. The water inlet end of the heat exchanger 21 is communicated with the water outlet end of the liquid-cooling tank, and the water outlet end of the heat exchanger 21 is communicated with the water inlet end of the liquid-cooling tank. The heat exchanger 21 includes an adjustment box 211 and heat exchange tubes 213. The adjustment box 211 is sequentially provided with a water inlet tank 202, a heat exchange tank 201, and a water outlet tank 203 along the direction of water flow. There are multiple heat exchange tubes 213, and the heat exchange tubes 213 are rotatably arranged in the heat exchange tank 201. A heat exchange liquid is provided in the heat exchange tank 201. A heat dissipation plate 214 fixedly connected is provided on the outer side of the heat exchange tube 213. The heat dissipation plate 214 is in a reciprocating thread shape. A synchronization plate 212 is provided in the heat exchange tank 201. Multiple adjustment holes for the heat dissipation plate 214 to pass through are provided on the synchronization plate 212. First crescent pins fixedly connected are provided on the inner walls of the adjustment holes. Sliding grooves 2141 for matching with the first crescent pins are provided on the heat dissipation plate 214. First brush wires that can be bent and are used for cleaning impurities on the surfaces of the heat dissipation plate 214 and the heat exchange tubes 213 are provided on the inner walls of the adjustment holes. The synchronization plate 212 is porous. The porous design can enable the synchronization plate 212 to reduce the movement resistance during movement and at the same time better change the flow direction of the heat exchange liquid, improving the heat exchange efficiency.

[0041] The liquid cooling method effectively reduces the noise pollution during traditional air cooling, making the main body 1 of the testing machine quieter during use. The design of the heat exchange tube 213, the heat dissipation plate 214, the synchronization plate 212, and the first crescent pin changes the original heat dissipation fins into a reciprocating thread shape. This not only ensures the heat exchange efficiency of the heat exchange tube 213 but also enables the heat exchange tube 213 to rotate. With the cooperation of the first crescent pin and according to the characteristics of the reciprocating thread, the synchronization plate 212 can reciprocate along the heat exchange tube 213. Then, in cooperation with the first brush wire, during the heat exchange process of the heat exchange tube 213, the first brush wire can continuously and automatically clean the impurities on the surfaces of the heat exchange tube 213 and the heat dissipation plate 214, effectively preventing the accumulation of impurities on the surfaces of the heat exchange tube 213 and the heat dissipation plate 214, which may lead to poor heat exchange efficiency. At the same time, the reciprocating movement of the synchronization plate 212 can make the heat exchange liquid in the heat exchange tank 201 flow, fully improving the contact probability between the heat exchange liquid and the heat exchange tube 213 and the heat dissipation plate 214, thereby improving the overall heat exchange efficiency.

[0042] In this embodiment, please refer to Figure 3 、 Figure 5 、 Figure 7 As shown in the figure, symmetrically distributed and fixedly connected adjusting plates 215 are provided in the adjusting box 211. The adjusting plates 215 divide the adjusting box 211 into a water inlet tank 202, a heat exchange tank 201, and a water outlet tank 203. A plurality of through holes that are rotationally and sealingly connected to the ends of the corresponding heat exchange tubes 213 are provided on the adjusting plates 215. A fixedly connected driving motor 218 is provided in the heat exchange box 2. The output end of the driving motor 218 is connected to one or more of the heat exchange tubes 213 through gears.

[0043] In this embodiment, please refer to Figure 7 As shown in the figure, a fixedly connected and annular first bevel gear 2183 is provided at the end of one of the heat exchange tubes 213. A second bevel gear 2182 that meshes with the first bevel gear 2183 is provided in the adjusting box 211. An output shaft 2181 is provided at the output end of the driving motor 218. The output shaft 2181 movably passes through the adjusting box 211 and is fixedly connected to the second bevel gear 2182, and the output shaft 2181 is rotationally and sealingly connected to the adjusting box 211. Through the cooperation of the first bevel gear 2183 and the second bevel gear 2182, the driving motor 218 drives the rotation of the heat exchange tube 213. Since the heat exchange tube 213 is rotationally connected to the adjusting plate 215, and combined with the characteristics of the first crescent pin and the reciprocating thread, as long as the rotation of one or several of the heat exchange tubes 213 can drive the movement of the synchronization plate 212, the first crescent pin in the synchronization plate 212 can drive the rotation of the other heat exchange tubes 213, realizing the synchronous rotation of all the heat exchange tubes 213.

[0044] In this embodiment, a plurality of heat dissipation grooves penetrating through the sliding grooves 2141 are provided on the heat dissipation plate 214, and the width of the heat dissipation grooves does not affect the sliding of the first crescent pin. The design of the heat dissipation grooves can fully increase the contact probability between the heat dissipation plate 214 and the heat exchange liquid, improving the heat exchange efficiency. Among them, the heat dissipation plate 214 can also be porous.

[0045] In this embodiment, there are a plurality of heat dissipation plates 214 on each heat exchange tube 213, and the number of synchronization plates 212 in the heat exchange tank 201 is the same as that of the heat dissipation plates 214. By adopting a design with multiple heat dissipation plates 214 and synchronization plates 212, the movement period of the synchronization plate 212 can be reduced. At the same time, the reciprocating movement of multiple synchronization plates 212 can further improve the flow efficiency of the heat exchange liquid in the heat exchange tank 201, thereby improving the overall heat exchange efficiency.

[0046] In this embodiment, please refer to Figure 2 , a first water pump 23 fixedly connected is provided in the heat exchange tank 2. The water outlet end of the first water pump 23 is communicated with the water inlet tank 202, and a water inlet pipe 22 is provided at the water inlet end of the first water pump 23. The water inlet pipe 22 is communicated with the water outlet end of the liquid cooling tank. One end of the water outlet tank 203 is provided with a communicating water outlet pipe 27, and the water outlet pipe 27 is communicated with the water inlet end of the liquid cooling tank. A filter 28 for filtering the passing liquid is provided on the water outlet pipe 27. A compressor 25 for cooling the passing liquid is provided in the heat exchange tank 2, and a second water pump 24 is also provided in the heat exchange tank 2. One end of the heat exchange tank 201 is provided with a communicating first pipe 29, and the other end of the heat exchange tank 201 is provided with a communicating second pipe 26. The first pipe 29 is communicated with the water inlet end of the second water pump 24. The water outlet end of the second water pump 24 is communicated with the water inlet end of the compressor 25. The water outlet end of the compressor 25 is communicated with the second pipe 26. The compressor 25 can cool the heat exchange liquid. Such a design can enable the heat exchange liquid to continuously cool the coolant. The addition of the filter 28 can timely collect the impurities in the coolant, effectively preventing the circulation of impurities.

[0047] In this embodiment, please refer to Figure 1 , a test chamber 12 is provided on the test machine main body 1. A placement plate 13 for placing the item to be tested is provided in the test chamber 12, and a test door 11 that can be opened and closed is provided at the inlet of the test chamber 12. A heat dissipation hole 14 is also provided on one side of the test machine main body 1.

[0048] As a feasible implementation manner, please refer to Figure 5 、 Figure 6, a cleaning disk 216 that can move back and forth and is used to clean the inner wall of the heat exchange tube 213 is provided in each of the heat exchange tubes 213. A second brush wire that can be bent and is used to clean the inner wall of the heat exchange tube 213 is further provided on the outer side of the cleaning disk 216. The design of the cleaning disk 216 and the second brush wire can utilize the back-and-forth movement of the cleaning disk 216 and cooperate with the second brush wire to realize the automatic cleaning inside the heat exchange tube 213, effectively preventing the accumulation of impurities on the inner wall of the heat exchange tube 213, thereby affecting the heat exchange efficiency.

[0049] In this embodiment, please refer to Figure 5 , Figure 6 , a second reciprocating thread 2131 is provided on the inner wall of the heat exchange tube 213, and a positioning rod 217 that is fixedly connected and prism-shaped is provided in the middle of each heat exchange tube 213. Both ends of the positioning rod 217 are fixedly connected to the inner wall of the corresponding adjustment box 211. The cleaning disk 216 is slidably connected to the positioning rod 217. The cleaning disk 216 is porous, and a second crescent pin that is fixedly connected and matches the corresponding second reciprocating thread 2131 is provided on the outer side of the cleaning disk 216.

[0050] Due to the characteristics of the second reciprocating thread 2131, since the heat exchange tube 213 is in a rotating state while the positioning rod 217 is in a fixed state, and at the same time the cleaning disk 216 can only reciprocate on the positioning rod 217, under the action of the second crescent pin, when the heat exchange tube 213 rotates, the cleaning disk 216 can reciprocate in the heat exchange tube 213, realizing the back-and-forth movement of the cleaning disk 216.

[0051] In this embodiment, the cleaning disk 216 is porous. The porous design of the cleaning disk 216 enables the coolant to change the movement trajectory inside the heat exchange tube 213 when passing through the cleaning disk 216, thereby increasing the contact probability between the coolant and the heat exchange tube 213 and improving the overall heat exchange efficiency.

[0052] In this embodiment, multiple second reciprocating threads 2131 can also be provided. The number of cleaning disks 216 corresponds to the number of second reciprocating threads 2131. By increasing the number of second reciprocating threads 2131, the number of cleaning disks 216 is increased, so that the porous cleaning disks 216 can change the flow trajectory of the coolant more frequently and improve the heat exchange efficiency.

[0053] The synchronous plate 212 and the first brush wire can clean the outer side wall of the heat exchange tube 213, and the cleaning disk 216 and the second brush wire can clean the inner wall of the heat exchange tube 213. Through the combination of internal and external cleaning, the accumulation of impurities on the inner and outer walls of the heat exchange tube 213 is effectively prevented, ensuring that the heat exchange tube 213 still has good heat exchange efficiency after being used for a period of time.

[0054] A testing method for a liquid-cooled aging tester, using the above-mentioned liquid-cooled aging tester, includes the following steps:

[0055] During the test of S1, the coolant cooled by the heat exchanger 21 in the heat exchange tank 2 is sent to the water inlet end of the liquid cooling tank. The cooled coolant is transported to the position that needs to be cooled in the tester main body 1 through the diversion of the liquid cooling tank, and heat exchange and cooling are carried out on it. Then, it flows back to the heat exchanger 21 through the drain end of the liquid cooling tank for re-heat exchange and cooling, so that the coolant can circulate and cool down;

[0056] When the coolant passes through the heat exchange tubes 213 in the heat exchanger 21, the rotation of the heat exchange tubes 213 is controlled. Since the heat dissipation plates 214 are in a reciprocating thread shape, and at the same time, multiple heat exchange tubes 213 all pass through the same synchronous plate 212, the synchronous plate 212 cannot rotate. Therefore, the rotation of the heat exchange tubes 213 enables the synchronous plate 212 to reciprocate back and forth on the heat exchange tubes 213 through the first crescent pin, so that the first brush wire can reciprocate back and forth to clean the surface of the heat exchange tubes 213, preventing the accumulation of impurities on the surface of the heat exchange tubes 213 and affecting the heat exchange efficiency of the heat exchange tubes 213.

8. A testing method for a liquid-cooled aging tester, using the liquid-cooled aging tester according to any one of claims 1 to 7, characterized in that: The following steps are involved: During the S1 test, the coolant in the heat exchange box that has been cooled by the heat exchanger is sent to the water inlet of the liquid cooling tank. The cooled coolant is transported to the position that needs to be cooled in the main body of the test machine through the diversion of the liquid cooling tank, and then returns to the heat exchanger through the drainage end of the liquid cooling tank for another heat exchange and cooling, so that the coolant can circulate and cool down; S2 When the coolant passes through the heat exchange tube in the heat exchanger, the heat exchange tube is controlled to rotate. Since the heat sink is in a reciprocating thread shape and multiple heat exchange tubes pass through the same synchronous plate, the synchronous plate cannot rotate. Therefore, the rotation of the heat exchange tube can be achieved through the first crescent pin, so that the synchronous plate can reciprocate on the heat exchange tube, so that the first brush wire can reciprocate to clean the surface of the heat exchange tube to prevent impurities from accumulating on the surface of the heat exchange tube and affecting the heat exchange efficiency of the heat exchange tube.
