Description

Technical Field

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

[0002] The purpose of aging testing is to expose potential design defects, material flaws or manufacturing process problems in advance by simulating the product's working state under harsh conditions such as long time and high load, so as to make timely improvements, thereby effectively reducing the product's failure rate during user use and improving the product's overall quality and market competitiveness.

[0003] Traditional aging test equipment mostly uses air cooling to dissipate heat. However, with the rapid development of electronic technology, the power density of electronic equipment continues to rise, and the heat generated has increased significantly. Air cooling has limited heat dissipation efficiency. When faced with high heat flux density, it is difficult to dissipate heat quickly and effectively, resulting in excessively high temperatures inside the test equipment. This will not only affect the accuracy and stability of the test results, but may also damage the product under test due to overheating, thereby reducing test efficiency and increasing test costs.

[0004] In contrast, liquid cooling technology has gradually become an ideal choice for solving high heat flux density heat dissipation problems due to its excellent heat dissipation performance. Liquid has higher specific heat capacity and thermal conductivity than gas, and can absorb and carry away more heat.

[0005] However, the inventors have discovered that, when using existing liquid cooling, due to the use of heat exchange tubes for heat exchange, a certain amount of impurities are likely to accumulate on the inner and outer surfaces of the heat exchange tubes after long-term use. The increase in impurities not only easily leads to blockage of the heat exchange tubes, but also greatly affects the heat exchange efficiency, resulting in a decrease in the heat exchange efficiency of the heat exchange tubes after a period of use.

[0017] A testing method for a liquid-cooled aging tester, using the liquid-cooled aging tester described above, comprises the following steps: 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.

[0018] Compared with the prior art, the present invention has the following technical effects: The liquid cooling method effectively reduces the noise pollution of traditional air cooling, making the main body of the test machine quieter when in use. The design of the heat exchange tube, the heat sink, the synchronous plate and the first crescent pin changes the original heat sink fins into a reciprocating thread shape, which not only ensures the heat exchange efficiency of the heat exchange tube, but also enables the synchronization plate to reciprocate along the heat exchange tube through the rotation of the heat exchange tube. Then, with the cooperation of the first crescent pin, according to the characteristics of the reciprocating thread, the synchronization plate can be reciprocated along the heat exchange tube, and then cooperate with the first brush wire, so that during the heat exchange process of the heat exchange tube, the first brush wire can continuously and automatically clean the impurities on the surface of the heat exchange tube and the heat sink, effectively preventing the accumulation of impurities on the surface of the heat exchange tube and the heat sink, resulting in poor heat exchange efficiency. At the same time, the reciprocating motion of the synchronous plate can make the heat exchange liquid in the heat exchange tank flow, which fully improves the contact probability between the heat exchange liquid and the heat exchange tube and the heat sink, thereby improving the overall heat exchange efficiency. The design of the cleaning disc and the second brush wire can utilize the back and forth movement of the cleaning disc in conjunction with the second brush wire to achieve automatic cleaning inside the heat exchange tube, effectively preventing the accumulation of impurities on the inner wall of the heat exchange tube, thereby affecting the heat exchange efficiency.

[0019] The synchronous plate and the first brush wire can clean the outer wall of the heat exchange tube, and the cleaning disk and the second brush wire can clean the inner wall of the heat exchange tube. The combination of internal and external cleaning can effectively prevent the accumulation of impurities on the inner and outer walls of the heat exchange tube, ensuring that the heat exchange tube still has good heat exchange efficiency after being used for a period of time.

[0035] Example 1, please refer to Figure 1 , Figure 2 and Figure 3 , Figure 4 , Figure 5 A liquid-cooled aging test machine comprises a test machine body 1, wherein the test machine body 1 is provided with a liquid cooling tank, and a heat exchange box 2 is provided on one side of the test machine body 1, wherein the heat exchange box 2 is provided with a heat exchanger 21 for adjusting the temperature of the coolant in the liquid cooling tank, wherein the water inlet end of the heat exchanger 21 is connected with the water outlet end of the liquid cooling tank, and the water outlet end of the heat exchanger 21 is connected with the water inlet end of the liquid cooling tank, wherein the heat exchanger 21 comprises a regulating box 211 and a heat exchange pipe 213, wherein the regulating box 211 is provided with a water inlet tank 202, a heat exchange tank 201 and a water outlet tank 203 in sequence along the direction of water flow, wherein the heat exchange pipe 213 is multiple, and the heat exchange pipe 213 is rotatable It is arranged in the heat exchange groove 201, and the heat exchange groove 201 is provided with a heat exchange liquid, and the heat exchange tube 213 is provided with a fixedly connected heat sink 214 on the outside, and the heat sink 214 is in a reciprocating thread shape, and the heat exchange groove 201 is provided with a synchronization plate 212, and the synchronization plate 212 is provided with a plurality of adjustment holes for the heat sink 214 to pass through, and the inner wall of the adjustment hole is provided with a fixedly connected first crescent pin, and the heat exchange plate 214 is provided with a slide groove 2141 for matching and slidingly connecting the first crescent pin, and the inner wall of the adjustment hole is provided with a bendable first brush wire for cleaning impurities on the surface of the heat exchange plate 214 and the heat exchange tube 213. The synchronization plate 212 is porous, and the porous design can reduce the movement resistance of the synchronization plate 212 during the movement, and at the same time, it can better change the flow direction of the heat exchange liquid and improve the heat exchange efficiency.

[0036] The liquid cooling method effectively reduces the noise pollution of traditional air cooling, making the test machine body 1 quieter when in use. The design of the heat exchange tube 213, the heat sink 214, the synchronization plate 212 and the first crescent pin changes the original heat sink fins into a reciprocating thread shape, which not only ensures the heat exchange efficiency of the heat exchange tube 213, but also enables the synchronization plate 212 to reciprocate along the heat exchange tube 213 through the rotation of the heat exchange tube 213 and the cooperation of the first crescent pin according to the characteristics of the reciprocating thread, and then The first brush wire is combined so that during the heat exchange process of the heat exchange tube 213, the first brush wire can continuously and automatically clean the impurities on the surface of the heat exchange tube 213 and the heat sink 214, effectively preventing the accumulation of impurities on the surface of the heat exchange tube 213 and the heat sink 214, which leads to poor heat exchange efficiency. At the same time, the reciprocating motion of the synchronization plate 212 can make the heat exchange fluid in the heat exchange tank 201 flow, which fully improves the contact probability between the heat exchange fluid and the heat exchange tube 213 and the heat sink 214, thereby improving the overall heat exchange efficiency.

[0037] In this example, see Figure 3 , Figure 5 , Figure 7 The regulating box 211 is provided with symmetrically distributed and fixedly connected regulating plates 215, and the regulating plates 215 divide the regulating box 211 into a water inlet tank 202, a heat exchange tank 201 and a water outlet tank 203. The regulating plate 215 is provided with a plurality of through holes that are rotatably and sealedly connected to the ends of the corresponding heat exchange tubes 213. The heat exchange box 2 is provided with a fixedly connected driving motor 218, and the output end of the driving motor 218 is connected to one or more of the heat exchange tubes 213 through a gear.

[0038] In this example, see Figure 7 , one of the heat exchange tubes 213 is provided with a first bevel gear 2183 fixedly connected and in a circular shape at the end thereof, the regulating box 211 is provided with a second bevel gear 2182 meshing with the first bevel gear 2183, the output end of the driving motor 218 is provided with an output shaft 2181, the output shaft 2181 is movable through the regulating box 211 and is fixedly connected with the second bevel gear 2182, and the output shaft 2181 is rotatably and sealedly connected with the regulating box 211. Through the cooperation of the first bevel gear 2183 and the second bevel gear 2182, the driving motor 218 drives the heat exchange tube 213 to rotate. Since the heat exchange tube 213 is rotatably connected to the regulating plate 215, coupled with the characteristics of the first crescent pin and the reciprocating thread, as long as one or more of the heat exchange tubes 213 rotate to drive the synchronous plate 212 to move, then the first crescent pin in the synchronous plate 212 can drive the other heat exchange tubes 213 to rotate, so that all the heat exchange tubes 213 can rotate synchronously.

[0039] In this embodiment, the heat sink 214 is provided with a plurality of heat sinks that cross the slide groove 2141, and the width of the heat sink does not affect the sliding of the first crescent pin. The design of the heat sink can fully increase the contact probability between the heat sink 214 and the heat exchange liquid, and improve the heat exchange efficiency. The heat sink 214 can also be porous.

[0040] In this embodiment, there are multiple heat sinks 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 sinks 214. The heat sinks 214 and synchronization plates 212 are designed to be multiple, thereby reducing the movement cycle of the synchronization plates 212. At the same time, the reciprocating motion of the multiple synchronization plates 212 can further improve the flow efficiency of the heat exchange fluid in the heat exchange tank 201, thereby improving the overall heat exchange efficiency.

[0041] In this example, see Figure 2 A fixedly connected first water pump 23 is provided in the heat exchange box 2, and a 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, and the water inlet pipe 22 is communicated with the water outlet end of the liquid cooling tank, and a connected water outlet pipe 27 is provided at one end of the water outlet tank 203, and the water outlet pipe 27 is communicated with the water inlet end of the liquid cooling tank, and a filter 28 for filtering the liquid passing through is provided on the water outlet pipe 27, a compressor 25 for cooling the liquid passing through is provided in the heat exchange box 2, and a second water pump 24 is also provided in the heat exchange box 2, a connected first pipe 29 is provided at one end of the heat exchange tank 201, and a connected second pipe 26 is provided at the other end of the heat exchange tank 201, 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, and 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 enables the heat exchange liquid to continuously cool the cooling liquid. The addition of the filter 28 can collect impurities in the cooling liquid in a timely manner, effectively preventing the circulation of impurities.

[0042] In this example, see Figure 1 The testing machine body 1 is provided with a testing cavity 12, the testing cavity 12 is provided with a placing plate 13 for placing the tested object, and the entrance of the testing cavity 12 is provided with an openable and closable testing door 11, and one side of the testing machine body 1 is also provided with a heat dissipation hole 14.

[0043] As a possible implementation, see Figure 5 , Figure 6The heat exchange tube 213 is provided with a cleaning disc 216 that can move back and forth and is used to clean the inner wall of the heat exchange tube 213. The outer side of the cleaning disc 216 is also provided with a second brush wire that can be bent and is used to clean the inner wall of the heat exchange tube 213. The design of the cleaning disc 216 and the second brush wire can utilize the back and forth movement of the cleaning disc 216 and cooperate with the second brush wire to achieve 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.

[0044] In this example, see Figure 5 , Figure 6 A second reciprocating thread 2131 is provided on the inner wall of the heat exchange tube 213, and a fixedly connected and prismatic positioning rod 217 is provided in the middle of the heat exchange tube 213. Both ends of the positioning rod 217 are respectively fixedly connected to the inner walls 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 fixedly connected and matching with the corresponding second reciprocating thread 2131 is provided on the outer side of the cleaning disk 216.

[0045] Through the characteristics of the second reciprocating thread 2131, since the heat exchange tube 213 is in a rotating state and the positioning rod 217 is in a fixed state, and 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 on the heat exchange tube 213, thereby realizing the back and forth movement of the cleaning disk 216.

[0046] In this embodiment, the cleaning disk 216 is porous. The porous design of the cleaning disk 216 can change the movement trajectory of the coolant in the heat exchange tube 213 when the coolant passes through the cleaning disk 216, thereby increasing the contact probability between the coolant and the heat exchange tube 213, thereby improving the overall heat exchange efficiency.

[0047] In this embodiment, the second reciprocating thread 2131 can also be set to multiple, and the number of the cleaning disks 216 corresponds to the second reciprocating thread 2131. By increasing the number of the second reciprocating threads 2131, the number of cleaning disks 216 is increased, so that the porous cleaning disk 216 can change the flow trajectory of the coolant more frequently, thereby improving the heat exchange efficiency.

[0048] The synchronization plate 212 and the first brush wire can clean the outer 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. By combining the 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.

[0049] A testing method for a liquid-cooled aging tester, using the liquid-cooled aging tester described above, comprises the following steps: During the S1 test, the cooling liquid in the heat exchange box 2 after being cooled by the heat exchanger 21 is sent to the water inlet end of the liquid cooling tank. The cooled cooling liquid is transported to the position in the test machine body 1 that needs to be cooled through the diversion of the liquid cooling tank, and is subjected to heat exchange and cooling. Then, it flows back to the heat exchanger 21 through the drainage end of the liquid cooling tank for another heat exchange and cooling, so that the cooling liquid can circulate and cool. S2 When the coolant passes through the heat exchange tube 213 in the heat exchanger 21, the heat exchange tube 213 is controlled to rotate. Since the heat sink 214 is in a reciprocating thread shape, and multiple heat exchange tubes 213 pass through the same synchronization plate 212, the synchronization plate 212 cannot rotate. Therefore, the rotation of the heat exchange tube 213 can be achieved through the first crescent pin, so that the synchronization plate 212 can reciprocate on the heat exchange tube 213, so that the first brush wire can reciprocate to clean the surface of the heat exchange tube 213 to prevent impurities from accumulating on the surface of the heat exchange tube 213 and affecting the heat exchange efficiency of the heat exchange tube 213.

10. A testing method for a liquid-cooled aging tester, using the liquid-cooled aging tester according to any one of claims 1 to 9, 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.
