[0002] A water-cooled plate heat exchanger is a device for transferring heat from a hot fluid to a cold fluid to meet specified process requirements;

[0003] New energy electric vehicles need to use water-cooled plates to dissipate heat from the batteries, which generate a large amount of heat during operation. The water-cooled plate is generally composed of a flow channel plate, a flat plate, and a connecting pipe. During production, the composite layer of the flow channel plate needs to be sprayed with solder.

[0004] During the brazing process of the liquid cooling plate, if the brazing temperature is too high and the composite layer is too thick, the brazing filler may accumulate in the flow channel after brazing, causing the flow channel to be blocked. The existing flow channel blockage detection method generally uses X-RAY detection, which has a high working time and can only be used for sampling inspection. It cannot directly detect the product after brazing, which may cause defective products to flow into the client and cause major product quality problems. SUMMARY

[0005] The purpose of the present application is to provide a liquid cooling plate inner block detection device and a detection method thereof.

[0039] Step two: test the inner plug of the liquid cooling plate by sleeving the cannula 62 on one connecting pipe of the liquid cooling plate, and leaving the other connecting pipe unsealed, and lifting the connecting pipe to move the limiting plate to the position between the two openings of the gas guide channel.

[0040] Step three: the inflation timing device timing time: 5-30s, the product is set to 100-400kpa, the gas extracted by the inflation pump 41 flows into the flow channel of the connecting pipe through the inflation pipeline 42 and the air guide channel, whether the floating ball 52 rises is observed, if the floating ball 52 rises, it proves that the flow channel is blocked, the gas flows into the leakage detection assembly 5 through the one-way air flow component 43, the air flow flows out from the bottom to the top, driving the floating ball 52 to rise, the inflation pump 41 starts after the digital keyboard 23 sets the inflation time, and stops automatically after the inflation time reaches the time set by the digital keyboard 23;

[0041] Step four: the floating ball 52 does not rise, and whether the alarm 32 rings and the gas detection qualified indicator lamp 21 is red is observed, and the alarm 32 rings and the gas detection qualified indicator lamp 21 is red, which indicates that the flow channel is in a smooth state, and the gas pressure in the inflation pipeline 42 cannot reach the set value;

[0042] Step five: manually place the connecting pipe for exhaust to feel whether there is air flow, after the air flow is exhausted, the exhaust connecting pipe is blocked by the plug, whether the alarm 32 stops ringing and the gas detection qualified indicator lamp 21 is green is observed, and whether the liquid cooling plate is bulging, leaking and appearing weld is observed, if one of the above problems appears, it is scrapped, and if the above problems do not appear, it is placed on the turnover car for transportation.

[0045] The button 22 is used to control the inflation pump 41 to start, and the digital keyboard 23 is used to set the inflation time of the inflation pump 41. The air pressure detection assembly 3 includes a real-time air pressure detection table 31, an alarm 32, an air pressure setting table 33 and an air pressure adjusting switch 34. The real-time air pressure detection table 31 and the alarm 32 are arranged horizontally and side by side on the top of the detection backboard 1. The air pressure adjusting switch 34 is connected with the air pressure setting table 33 and used to adjust the air pressure setting value. The real-time air pressure detection table 31, the air pressure setting table 33 and the alarm 32 are connected on the connecting circuit board through wires. The air pressure value in the inflation assembly 4 obtained by the real-time air pressure detection table 31 is compared with the set air pressure value of the air pressure setting table 33 on the comparator on the circuit board. If the air pressure value in the inflation assembly 4 is less than the set value of the air pressure setting table 33, the alarm 32 will alarm because the set value is not reached.

[0046] The inflation assembly 4 includes an inflation pump 41, an inflation pipeline 42 and a one-way air flow component 43. The inflation pump 41 and the one-way air flow component 43 are assembled on the detection backboard 1 by bolts. The pipe opening of the inflation pump 41 is connected with one end of a multi-way pipe. The remaining two ends of the multi-way pipe are connected with the inflation pipeline 42 and the one-way air flow component 43 respectively. The inflation pipeline 42 is connected with the inflation air detection connector 6.

[0047] When the flow channel is not blocked, the gas of the inflation pump 41 flows out from the inflation pipeline 42, and the one-way air flow component 43 limits the gas to flow into the leakage detection assembly 5.

[0048] The one-way air flow component 43 includes a one-way shell 431, a one-way pipe 432, a sealing plate 434, an extension rod 435 and a spring 436. The one-way shell 431 is arranged on the detection backboard 1. A partition plate 437 is arranged inside the one-way shell 431 and is divided into a left cavity and a right cavity.

[0049] The middle part of the partition plate 437 is a through slot. The sealing plate 434 is arranged in the right cavity. A sealing ring is sleeved on the edge of the sealing plate 434. The two ends of the extension rod 435 are connected with the sealing plate 434 and the inner wall of the one-way shell 431 respectively. The sealing plate 434 is connected with the partition plate 437 through the sealing ring and covers the slot of the partition plate 437. The spring 436 is sleeved on the extension rod 435. The two ends of the spring 436 are connected with the sealing plate 434 and the inner wall of the one-way shell 431 respectively.

[0050] One pipe opening of the multi-way pipe is communicated with the left cavity. The right cavity is communicated with one end of the one-way pipe 432.

[0051] With the setting that the sealing plate 434 is pressed by the spring 436, in the state that the flow channel is open, the gas flow can flow out of the flow channel, and the elasticity of the gas flow pressing the sealing plate 434 is smaller than the elasticity of the spring 436 supporting, so that the spring 436 pushes the sealing plate 434 against the partition plate 437, and the slot hole of the partition plate 437 covers and seals. If the flow channel is blocked, the gas flow acts on the sealing plate 434, and pushes the sealing plate 434 to move along the telescopic rod 435, and the gas flow flows into the bottom of the flowmeter 51 through the right cavity.

[0052] The leakage detection assembly 5 includes the flowmeter 51, the floating ball 52 and the suspension rope 53, the bottom end of the flowmeter 51 is communicated with the other end of the one-way pipe 432, and the floating ball 52 is fixed with the top wall of the flowmeter 51 through the suspension rope 53.

[0053] The upward flowing process of the gas flow drives the floating ball 52 to float upward, which proves that the flow channel is blocked, and whether there is leakage can be directly observed by the upward floating of the floating ball 52.

[0054] The inflation gas detection connector 6 includes a connector body 61, a plug pipe 62, an upper sealing ring 63, a lower sealing ring 64, a guide column 65, a supporting ring 66 and a reset spring 67, the connector body 61 is a tubular member with one end closed and one end open, the plug pipe 62 is connected with the middle part of the connector body 61 to form a “T” shape, and the inner wall of the plug pipe 62 is provided with the upper sealing ring 63 and the lower sealing ring 64.

[0055] The supporting ring 66 is arranged in the plug pipe 62 above the upper sealing ring 63, one end of the guide column 65 is fixed on the connector body 61, the other end of the guide column 65 passes through the through hole in the middle part of the supporting ring 66, a limiting plate is sleeved on the guide column 65, the limiting plate is connected with the inner wall of the connector body 61 through the reset spring 67, and the limiting plate also abuts against the supporting ring 66.

[0056] The guide column 65 is also provided with a gas guide channel, and two openings of the gas guide channel are located on the side peripheral surface of the guide column 65.

[0057] When the plug pipe 62 is sleeved on the connecting pipe, the upper sealing ring 63 and the lower sealing ring 64 are in contact with the outer wall of the connecting pipe, the sealing of the connection is increased by double sealing, and when the plug pipe 62 is sleeved on the connecting pipe, the limiting plate is lifted along the guide column 65 by the extrusion of the connecting pipe, after the limiting plate is lifted to be in contact with the supporting rod in the connector body 61, the limiting plate is position-limited and cannot be further moved, then the limiting plate is located between the two openings, the gas in the connector body 61 enters the plug pipe 62 along the gas guide channel, and then is discharged into the flow channel, so that the detection of the internal blockage is realized.

[0058] When the plug pipe 62 and the connecting pipe are separated, the reset spring 67 pushes the limiting plate to move, so that the separation is realized, and the problem that the gas is sprayed to cause the objects to splash and cause danger is avoided when the plug pipe 62 and the connecting pipe are separated.

[0059] Working principle: The gas detection equipment is modified. Before gas detection, the connector body 61 is used to inflate the product inlet connection pipe with the insertion pipe 62, and the hand is used to detect whether the gas outlet connection pipe is discharged, and whether the floating ball 52 on the leakage detection assembly 5 rises is observed. If the floating ball rises, the product flow channel is blocked. Otherwise, the flow channel of the liquid cooling plate is blocked. The effect of 100% rapid detection of product flow channel blockage is achieved.
