[0026] In the field of chip testing, system-level testing (SLT) involves inserting semiconductor bare chips into a tester that simulates the real functions of the operating chip to verify its internal timing paths and functional interfaces. In order to meet the temperature requirements during testing, SLT needs to be equipped with a water circulation system to cool the system during the test. However, during use, the SLT test water circulation system has the problem of impurities blocking the water path. For this reason, it is necessary to regularly replace the cooling water and clean the water path.

[0027] The existing method of cleaning the water channel is to inject deionized water into the water channel and apply compressed gas to the water channel so that the water channel is filled with mixed water and gas to achieve the purpose of cleaning. However, when the mixed water and gas return to the refrigerator, they will boil violently in the water tank of the refrigerator, forming water splashes, which is easy to cause environmental pollution, damage the health of users, and increase the amount of deionized water used.

[0028] To this end, the embodiments of the present application provide a splash-proof device and an SLT test water circulation system to improve the current problem of easily causing environmental pollution, harming the health of users, and increasing the use of deionized water when cleaning the water channel of the SLT test water circulation system.

[0029] In order to make the objectives, technical solutions and advantages of the present application more clear, they are described in detail below with reference to specific drawings and embodiments.

[0030] Figure 1 A schematic structural diagram of a refrigerator provided in an embodiment of the present application is shown. Figure 2 A schematic structural diagram of a water splash prevention device provided in an embodiment of the present application is shown. Figure 3 A schematic structural diagram of a water-gas separation component provided in an embodiment of the present application is shown.

[0031] refer to Figure 1 The SLT test water circulation system provided in the embodiment of the present application includes a refrigerator 100, which has a water tank and a water tank water inlet 101, a cooling water outlet 102 and a cooling water return port 103 arranged in the water tank. The water tank water inlet 101 is used to inject cooling water into the water tank. The cooling water can be clean water that meets the water quality standard or an aqueous solution containing 15% ethylene glycol. The cooling water outlet 102 and the cooling water return port 103 are used to connect the two ends of the circulating water circuit respectively.

[0032] The process of cooling the SLT test water circulation system is as follows: start the refrigerator 100, the refrigerator 100 works and reduces the temperature of the cooling water in the water tank. The cooling water in the water tank flows into the circulating water circuit from the cooling water outlet 102 under the action of power. The cooling water absorbs system heat when passing through the circulating water circuit, and finally returns to the water tank from the cooling water return port 103 to achieve system cooling of the SLT.

[0033] The process of water channel cleaning in the SLT test water circulation system is as follows: deionized water is injected into the water tank, and compressed gas is applied to the circulating water channel to fill the circulating water channel with mixed water gas. The mixed water gas moves in the circulating water channel while cleaning the circulating water channel to achieve cleaning of the circulating water channel.

[0034] It should be understood that during the water cleaning process of the SLT test water circulation system, in order to avoid excessive air pressure in the water tank, the water tank water filling port 101 needs to be kept open. However, this will also cause water to splash out from the water tank water filling port 101.

[0035] refer to Figure 2 The SLT test water circulation system of the embodiment of the present application may further include a water splash prevention device 200. The water splash prevention device 200 is used to be arranged at the water tank water filling port 101 of the SLT test water circulation system to prevent water in the water tank from splashing out.

[0036] refer to Figure 2 Optionally, in the embodiment of the present application, the anti-splashing device 200 may include: a device body 210, a working channel 220 and a water-gas separation component 230. The device body 210 is used to connect with the water tank. The working channel 220 is arranged in the device body 210 from top to bottom, and the lower end of the working channel 220 is connected to the water tank water filling port 101 when the device body 210 is connected with the water tank. The water-gas separation component 230 is arranged in the working channel 220, and the water-gas separation component 230 is configured to limit the passage of splashing water so that it can flow back to the water tank.

[0037] According to the above-mentioned water splash prevention device 200, its water-gas separation component 230 can allow gas to be discharged through the working channel 220 to reduce the air pressure in the water tank and prevent the equipment from being damaged due to excessive air pressure inside the water tank. On the other hand, the water-gas separation component 230 can prevent splashing water from splashing out through the working channel 220 and falling on surrounding instruments, the ground or users, so that deionized water can be prevented from polluting the environment and damaging the health of users, and safety hazards can be reduced.

[0038] In addition, since the working channel 220 is arranged from top to bottom, the deionized water can flow back to the water tank after being blocked by the water-gas separation component 230. In this way, the need to continue to inject deionized water into the circulating water circuit due to the loss of deionized water can be avoided, which is beneficial to saving the use of deionized water and reducing cleaning costs.

[0039] refer to Figure 2 Optionally, in the embodiment of the present application, the device body 210 may be a tubular structure. In other words, the lumen of the device body 210 is the working channel 220. This arrangement can simplify the structure of the anti-splash device 200 and reduce costs.

[0040] Optionally, in the embodiment of the present application, the device body 210 may be a straight tube structure.

[0041] Optionally, in the embodiment of the present application, the device body 210 may be a curved tube structure. It should be understood that in order to avoid loss of deionized water due to water accumulation in the working channel 220, the device body 210 should avoid bending up and down.

[0042] refer to Figure 2 Optionally, in the embodiment of the present application, the device body 210 may be provided with a connection portion 211, the connection portion 211 is located at the lower end of the working channel 220, and the connection portion 211 is used to connect with the water tank water inlet 101. This arrangement can realize the connection between the device body 210 and the water tank, and can facilitate the alignment of the working channel 220 and the water tank water inlet 101 to ensure the connection sealing performance.

[0043] Optionally, in the embodiment of the present application, the connection portion 211 and the water tank water inlet 101 can be connected by a screw connection or a clamping connection. Preferably, the connection portion 211 and the water tank water inlet 101 are connected by a threaded connection. In this way, the water tank water inlet 101 can be connected to the connection portion 211 by means of the original threaded structure, without the need to set an additional connection structure at the water tank water inlet 101, which is conducive to simplifying the structural design and reducing costs.

[0044] Optionally, in the embodiment of the present application, the connection part 211 and the device body 210 may be an integral structure. This arrangement can improve the connection strength between the connection part 211 and the device body 210 and ensure the reliability of the structure.

[0045] refer to Figure 2 , optionally, in an embodiment of the present application, the working channel 220 may include a first working section 221 and a second working section 222. The first end of the first working section 221 is connected to the water tank water inlet 101, the second end of the first working section 221 is connected to the second working section 222, and the caliber of the first working section 221 is smaller than the caliber of the second working section 222. This arrangement can reduce the speed of deionized water, thereby reducing the impact of low deionized water on the internal structure. Specifically, when deionized water flows from the first working section 221 into the second working section 222, as the caliber of the second working section 222 becomes larger, the speed of the deionized water decreases, and the impact force of the deionized water on the internal structure of the second working section 222 (such as: gas-water separation component, etc.) is reduced, thereby reducing the risk of damage to the device.

[0046] Optionally, in the embodiment of the present application, in the installed state, the axis of the working channel 220 may coincide with the vertical direction.

[0047] Optionally, in the embodiment of the present application, in the installed state, the axis of the working channel 220 may have an angle with the vertical direction. For example, the angle between the axis of the working channel 220 and the vertical direction may be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75° or 80°, etc. It should be understood that the angle between the axis of the working channel 220 and the vertical direction may be specifically selected according to actual needs and is not limited to the above angle values.

[0048] refer to Figure 2 and Figure 3 Optionally, in the embodiment of the present application, the water-gas separation component 230 may include a baffle, and the baffle includes a plate body 231 and a vent hole 232 disposed on the plate body 231. That is, the baffle may be a mesh structure. In a specific implementation, the vent hole 232 is used to allow gas to pass through so that it can be discharged through the working channel 220. The plate body 231 is used to block deionized water so that the deionized water can flow back into the water tank along the working channel 220. This arrangement can prevent deionized water from splashing out from the water tank water inlet 101.

[0049] refer to Figure 3 Optionally, in the embodiment of the present application, the air holes 232 can be evenly distributed on the entire baffle.

[0050] refer to Figure 3 Optionally, in the embodiment of the present application, the air holes 232 may be evenly distributed in a local position of the baffle. For example, the air holes 232 may be distributed in a middle area or an edge area of ​​the baffle.

[0051] Optionally, in the embodiment of the present application, the aperture of the air vent 232 is not greater than 4 mm. For example, the aperture of the air vent 232 may be 1 mm, 2 mm, 3 mm, or 4 mm, etc. It should be understood that the aperture of the air vent 232 may be specifically selected according to actual needs and is not limited to the above aperture values.

[0052] Optionally, in an embodiment of the present application, there are multiple baffles, and the multiple baffles are arranged at intervals along the axial direction of the working channel 220. This arrangement can improve the effect of gas-water separation and ensure the reliability of the gas-water separation component. Specifically, deionized water will pass through the vents when it surges or splashes and continue to splash outward. However, deionized water will experience energy loss when passing through the vents, thereby reducing the speed of the deionized water. Therefore, by setting up multiple baffles, the speed of the deionized water can be reduced layer by layer, and ultimately the deionized water cannot pass through the blocked vents 232. In addition, compared with the setting method of a single baffle, by setting up multiple baffles, multiple baffles can share the impact force of the deionized water, thereby reducing the impact force received by each baffle, which can reduce the material requirements for the baffles and help reduce costs.

[0053] refer to Figure 2 and Figure 3 Optionally, in the embodiment of the present application, the baffle includes a first baffle 230a, a second baffle 230b and a third baffle 230c, and the first baffle 230a, the second baffle 230b and the third baffle 230c are arranged at intervals along the axial direction of the working channel 220, the first baffle 230a is located on the side of the second baffle 230b close to the water tank water inlet 101, and the third baffle 230c is located on the side of the second baffle 230b away from the water tank water inlet 101. When the deionized water passes through the air holes 232 of the first baffle 230a, the speed of the deionized water will be reduced, and when the deionized water passes through the air holes 232 of the second baffle 230b, the speed of the deionized water will be further reduced, so that the deionized water can not finally pass through the air holes 232 of the third baffle 230c.

[0054] Optionally, in the embodiment of the present application, one of the multiple baffles can be disposed at the lower end of the working channel 220, that is, the position where the working channel 220 is connected to the water tank water inlet 101. In this way, the deceleration position of the deionized water can be moved forward, thereby reducing the splash height of the deionized water as much as possible, which is conducive to reducing the length of the working channel 220 and the number of baffles used.

[0055] refer to Figure 2 Optionally, in the embodiment of the present application, the baffle may further include a fourth baffle 230d, and the fourth baffle 230d is located in the connecting portion 211. It should be understood that since the lower end of the working channel 220 belongs to the first working section 221, the radius of the fourth baffle 230d should be appropriately reduced compared to the baffle arranged in the second working section 222 to meet the installation requirements.

[0056] refer to Figure 3 Optionally, in the embodiment of the present application, the air holes 232 of two adjacent baffles can be staggered. For example, the air holes 232 on the first baffle 230a are located at the rear edge of the first baffle 230a (eg Figure 2 The air vent 232 on the second baffle plate 230b is located at the front edge of the second baffle plate 230b (eg, Figure 2The air holes 232 on the third baffle plate 230c are located in the middle of the third baffle plate 230c. This arrangement can further reduce the flow rate of deionized water, thereby improving the effect of gas-water separation. Specifically, since the air holes 232 of two adjacent baffle plates are staggered, the deionized water needs to turn when passing through the air holes 232 of the next baffle plate, such as: the deionized water passing through the first baffle plate 230a needs to turn to the front edge position of the second baffle plate 230b before passing through the second baffle plate 230b, and the deionized water passing through the second baffle plate 230b needs to turn to the middle position of the third baffle plate 230c before passing through the third baffle plate 230c. Each turn will cause energy loss of the deionized water, thereby reducing the flow rate of the deionized water.

[0057] Optionally, in the embodiment of the present application, the baffle plate may be provided with a reflux hole 233, which is used to allow splashing water to flow back. This arrangement can avoid local water accumulation in the working channel 220. Specifically, when the baffle plate has an angle with the horizontal direction, a groove can be formed between the baffle plate and the working channel 220, and the groove can accumulate deionized water so that it cannot flow back. By providing the reflux hole 233 at the position of the baffle plate corresponding to the bottom of the groove, the above problem can be avoided.

[0058] One or more embodiments of this specification are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification should be included in the scope of protection of this application.

[0059] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
