DETAILED DESCRIPTION

[0031] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0032] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] Power equipment can be divided into external cooling and internal cooling according to the cooling method. External cooling equipment uses fans or natural ventilation to allow air to flow through the outside of the equipment to remove heat. Internal cooling equipment designs the key heat dissipation structure to be hollow, and passes liquid cooling medium inside the structure to remove heat from the inside of the equipment to achieve heat dissipation effect. The internal cooling system can be divided into water cooling and evaporative cooling according to the cooling medium. It has the material property that the specific heat capacity of the cooling medium is greater than that of air. During the cooling process, the cooling medium of the water cooling system remains in liquid state, while the cooling medium of the evaporative cooling system undergoes phase change at high temperature, boils and vaporizes, and removes heat through vaporization latent heat to achieve efficient cooling.

[0034] During the operation of power equipment, the equipment is subjected to combined mechanical, thermal and electrical stresses. Since the heat dissipation efficiency of the internal cooling system is higher than that of the air cooling method, the temperature of the internal cooling equipment is not only lower than that of the air cooling equipment, but the stress distribution it is subjected to is also significantly different from that of the air cooling equipment. During the operation of some equipment, rapid temperature changes often occur, causing the equipment to experience significant stress. After long-term operation, this hot and cold cycle process will cause damage to the equipment, and in severe cases may affect normal operation. In order to ensure the long-term safe and reliable operation of the equipment, it is necessary to conduct hot and cold cycle aging tests on the equipment to explore whether its performance meets the long-term operation requirements.

[0035] The heating methods of existing hot and cold cycle aging devices include directly connecting to voltage and current sources, hot air blowers or heating plates, etc., and the cooling methods include using fans to blow in external cold air, refrigeration plates, natural cooling, or using liquid nitrogen to simulate low-temperature environments, etc. The principle of the above cooling methods is to allow relatively low-temperature gas to flow through the surface of the test piece to take away heat, thereby cooling it down. There are also improvements to conventional hot and cold cycle aging devices in the prior art. For example, vertical partitions, fixed orifice plates, and movable orifice plates are added to the aging box to adjust the cooling speed of the fan and evenly cool the test piece; as another example, the prior art proposes a hot and cold cycle aging device that can automatically complete temperature control without human supervision; the prior art provides a multi-factor aging performance detection scheme including hot and cold cycle aging; the prior art adds ultraviolet aging detection or simulated light source devices based on hot and cold cycle aging according to the functional requirements of the equipment.

[0036] The existing patents for hot and cold cycle aging devices for power equipment have been optimized in terms of improving the cooling uniformity of test samples, achieving automatic temperature control, multi-factor aging and composite equipment functional requirements, but their cooling systems all dissipate heat and cool down the outside of the equipment, and have not optimized the cooling structure of the test device based on the cooling characteristics of internally cooled equipment.

[0037] For externally cooled power equipment, the cooling method of the hot and cold cycle aging device is similar to the cooling method of the equipment during actual operation, and can better simulate the actual working conditions. However, internally cooled equipment removes heat through the internal cooling medium, and the temperature and stress distribution are quite different from those of externally cooled equipment. If the existing hot and cold cycle aging device is used to perform aging tests on internally cooled equipment, it is difficult to better simulate the actual temperature changes and stress conditions of the internally cooled equipment, which in turn affects the judgment of the aging degree of the equipment and the ability to resist hot and cold cycle aging, and reduces the accuracy and effectiveness of the test. Therefore, for internally cooled power equipment, if the internal cooling system can be used to achieve cooling in the hot and cold cycle aging test based on its cooling characteristics, it will better simulate the actual working conditions and improve the accuracy of the test results.

[0038] In order to solve the above technical problems, Figure 1 and Figure 6 As shown, the present application provides an internal cooling equipment aging device, comprising:

[0039] The heat preservation box 1 comprises a box body 11 and a box door 12, wherein a first electromagnetic induction coil 112 is disposed on the side wall of the box body 11, and a second electromagnetic induction coil 120 corresponding to the first electromagnetic induction coil 112 is disposed on the box door 12;

[0040] An internal cooling device 3, the internal cooling device 3 is rotatably disposed in the heat preservation box 1, and a cooling liquid is provided in the internal cooling device 3, and the cooling liquid includes a plurality of induction coils 5;

[0041] When the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are powered on, a magnetic field 6 is formed. When the internal cooling device 3 rotates in the magnetic field 6, the multiple induction coils 5 float and move in the coolant and generate heat.

[0042] Specifically, the heat preservation box 1 includes a box body 11 and a box door 12, and the box door 12 is installed on the side wall of the box body 11, so that it is convenient to install the internal cooling device 3. A first electromagnetic induction coil 112 is provided on the side wall inside the box body 11, that is, the side wall opposite to the box door 12, and a second electromagnetic induction coil 120 is provided on the box door 12, so that the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are symmetrically arranged, so that a stronger magnetic field 6 can be generated. The first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are connected to a power source. After the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are powered on, a magnetic field 6 is formed between the two electromagnetic induction coils. After the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are powered off, the temperature inside the heat preservation box 1 drops. The internal cooling device 3 is rotatably arranged in the heat preservation box 1. After the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are energized, the internal cooling device 3 is located in the magnetic field 6. A coolant is provided in the internal cooling device 3, and a plurality of induction coils 5 are placed in the coolant. When the internal cooling device 3 rotates, the induction coil floats and moves in the coolant, thereby generating heat to heat the coolant. When the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are powered off, the temperature of the coolant drops, thereby being able to better simulate the actual temperature change and stress condition of the internal cooling device 3, thereby improving the judgment of the aging degree of the equipment and the ability to resist cold and hot cycle aging, and improving the test accuracy and effectiveness.

[0043] In some embodiments, Figure 1 , Figure 3 As shown, a coolant inlet 31 and a coolant outlet 32 ​​are provided on the side wall of the internal cooling device 3 .

[0044] Specifically, a coolant inlet 31 and a coolant outlet 32 ​​are provided on the side wall of the internal cooling device 3. The coolant inlet 31 and the coolant outlet 32 ​​can be symmetrically arranged on the left and right sides of the internal cooling device 3, or on the upper and lower sides of the internal cooling device 3. The coolant inlet 31 and the coolant outlet 32 ​​can also be arranged at will, and this application does not make any specific restrictions.

[0045] Exemplarily, the internal cooling device 3 can be any one of a rectangular, square, oblong, circular, elliptical, etc., which is not specifically limited in this application. In this application, a rectangular shape is taken as an example. A cavity for placing a coolant is provided in the internal cooling device 3, and a coolant inlet 31 and a coolant outlet 32 ​​are connected to the cavity.

[0046] In some embodiments, Figure 1 , Figure 3 As shown, the coolant inlet 31 and the coolant outlet are both provided with blocking members.

[0047] Specifically, after the coolant is poured into the cavity of the internal cooling device 3 , the coolant is sealed in the internal cooling device 3 by the blocking member, so as not to affect the rotation of the internal cooling device 3 during the test.

[0048] In some embodiments, Figure 4 , Figure 5 and Figure 8 As shown, the internal cooling device 3 is connected to a refrigeration system 4 via the coolant inlet 31 and the coolant outlet 32 ​​.

[0049] Specifically, in this embodiment, exemplarily, the coolant inlet 31 is arranged at the bottom of the internal cooling device 3, and the coolant outlet 32 ​​is arranged at the top of the internal cooling device 3. The coolant inlet 31 is connected to the water outlet of the refrigeration system 4 through the water inlet pipe 41, and the coolant outlet 32 ​​is connected to the return water port of the refrigeration system 4 through the water outlet pipe 42.

[0050] The refrigeration system 4 includes a first pressure sensor, a condenser, a coolant tank, and a second pressure sensor connected in sequence. The first pressure sensor is arranged at the coolant outlet 32, and the second pressure sensor is arranged at the coolant inlet 31. The first pressure sensor and the second pressure sensor cooperate to detect the flow rate of the cavity coolant in the internal cooling device, and can detect whether there is a blockage in the internal cooling device to improve the detection effect. The condenser is used to cool the coolant flowing out of the internal cooling device and then flow it into the coolant tank. A water regulating valve can also be set at the outlet of the coolant tank.

[0051] In some embodiments, Fig.10As shown, a temperature measuring element is provided on the outer wall of the internal cooling device. Specifically, for example, the temperature measuring element is a temperature sensor that can adjust the detection temperature during the detection of the internal cooling device, and can better simulate the actual temperature change and stress of the internal cooling device 3.

[0052] In some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the thermal insulation box 1 is provided with an installation component 2 for installing the internal cooling device 3, and the installation component 2 includes a supporting component and a tightening component 22. The supporting component is rotatably arranged at the bottom of the thermal insulation box 1, and the tightening component 22 is arranged at the top of the thermal insulation box 1, and the internal cooling device 3 is arranged between the supporting component and the tightening component 22.

[0053] Specifically, the internal cooling device 3 can be rotatably installed in the insulation box 1. Since the internal water cooling device needs to rotate in the magnetic field 6 when the coolant inside the internal cooling device 3 is heated, it is necessary to provide an installation component 2 for rotating the internal cooling device inwardly of the insulation box. The installation component 2 includes a support component and a tightening component 22. The support component is rotatably set at the bottom of the insulation box 1, and the tightening component 22 is set at the top of the insulation box 1. The internal cooling device 3 is set between the support component and the tightening component 22. That is to say, after the internal cooling device 3 is placed on the support component, it is tightened by the tightening component 22, which can ensure the stable installation of the internal cooling device 3.

[0054] In some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the support assembly includes a support frame 212 and a clamping assembly 21.

The support frame 212 rotates the device at the bottom of the insulation box 1, and the clamping assembly 21 is pulled out and set in the support frame 212. In this way, after the internal cooling device 3 is placed on the support frame 212, it can be clamped by the clamping assembly 21 to avoid the internal cooling device 3 from being displaced during the rotation process and rubbing against the box body 11 of the insulation box 1, which may cause damage to the equipment. The stability of the test can also be ensured.

[0057] Specifically, a first drive motor 211 is provided at the bottom of the outer wall of the thermal insulation box 1. The first drive motor 211 penetrates the thermal insulation box 1 and is connected to the support frame 212. The first drive motor 211 is used to drive the support frame 212 to rotate, and can drive the internal cooling device 3 on the support frame 212 to rotate, so that the internal cooling device 3 can be rotated in the magnetic field 6, thereby increasing the temperature of the internal cooling device 3 during the test process.

[0058] In some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, a bottom plate 110 is provided at the bottom of the thermal insulation box 1 , a slide groove 111 is provided on the bottom plate 110 , and a slide rod 217 corresponding to the slide groove 111 is provided at the bottom of the support frame 212 .

[0060] In some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the clamping assembly 21 includes a first clamping rod 214, a second clamping rod 215, a gear 2121 and a second driving motor 213. A cavity is provided inside the support frame 212, and the gear 2121 is rotatably arranged in the cavity. The second driving motor 213 is arranged on the side wall of the support frame 212, and the rotating shaft of the second driving motor 213 passes through the support frame 212 and is connected to the gear 2121. The first clamping rod 214 and the second clamping rod 215 symmetrically pass through the side wall of the support frame 212 and mesh with the gear 2121.

[0061] Specifically, the clamping assembly 21 includes a first clamping rod 214, a second clamping rod 215, a gear 2121 and a second drive motor 213. The rotating shaft of the second drive motor 213 passes through the side wall of the support frame 212 and is connected to the gear 2121. The first clamping rod 214 passes through the right side wall of the support frame 212 and extends into the cavity. A rack is provided on the upper end surface of the first clamping rod 214, and the rack is meshed with the gear 2121. A rack is provided on the lower end surface of the second clamping rod 215. The second clamping rod 215 passes through the support frame 212 and extends to the cavity to mesh with the gear 2121. The gear 2121 meshes with the two clamping rods. When the gear 2121 rotates, it can drive the two clamping rods to move in opposite directions, thereby achieving clamping. When the clamping assembly 21 clamps the internal cooling device 3, the stable installation of the internal cooling device 3 can be guaranteed.

[0062] In some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the lifting assembly includes a cylinder 221 and a top plate 222, wherein the cylinder 221 is arranged on the top outside the heat preservation box 1, and the top plate 222 is located inside the heat preservation box 1, and the cylinder 221 penetrates the heat preservation box 1 and is rotatably connected to the top plate 222.

[0063] Specifically, the lifting assembly is used to place the internal cooling device 3 on the support assembly and tighten it, which can ensure the stable installation of the internal cooling device 3. The lifting assembly is arranged on the top of the heat preservation box 1, and the lifting assembly includes a cylinder 221 and a top plate 222. The cylinder 221 is arranged on the top outside the heat preservation box 1, and the cylinder rod penetrates the heat preservation box 1 and is connected to the top plate 222. The cylinder 221 controls the top plate 222 to move up and down, which can tighten the internal cooling device 3 and further limit the internal cooling device 3.

[0064] In some embodiments, Figure 5 As shown, a refrigeration pipeline 13 is provided in the heat preservation box 1 , and the refrigeration pipeline 13 is connected to a refrigeration system 4 .

[0065] Specifically, for example, a plurality of refrigeration pipes 13 (not shown in the figure) are wound around the inner wall of the insulated box 1, and the inlet and outlet of the refrigeration pipes 13 are arranged through the side wall of the insulated box 1, and are connected to the refrigeration system 4 through the coolant inlet and outlet pipes to achieve cooling of the inside of the insulated box 1. The specific refrigeration system 4 is consistent with the refrigeration system 4 of the above embodiment, and will not be described in detail here.

[0066] In this embodiment, after the internal cooling device 3 is filled with coolant, the coolant is sealed in the cavity of the internal cooling device 3 through the sealing member. Then, during the test, the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are energized to form a magnetic field 6, so that the internal cooling device 3 rotates in the field, and the induction coil 5 in the internal cooling device 3 floats in the coolant to generate heat, heating the coolant, thereby achieving heating of the temperature during the internal cooling device test. After the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are powered off, the refrigeration pipeline 13 in the heat preservation box 1 is refrigerated by the refrigeration system 4, and the temperature in the heat preservation box 1 is reduced, thereby achieving cooling of the temperature during the internal cooling device test. Therefore, the hot and cold cycle test during the test of the internal cooling device 3 is achieved through the magnetic field 6 and the refrigeration system 4.

[0068] Specifically, when the internal cooling device 3 needs to be heated, the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are energized (the energization method can be Fig.10 The heating power supply is turned on, wherein the heating power supply line passes through the insulation box and is connected to the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 to realize the power supply to the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120), when the first drive motor 211 drives the first gear 2111 to rotate, the first gear 2111 drives the second gear 2112 to rotate, the second gear 2112 drives the bearing 2113 to rotate, the bearing 2113 drives the support frame 212 to rotate, and the support frame 212 drives the internal cooling device 3 to rotate, thereby realizing the internal cooling device 3 to rotate in the magnetic field 6, when it is necessary to perform a cooling test on the internal cooling device 3, the refrigeration system 4 is turned on, the coolant in the refrigeration system 4 is circulated, and a cooling cycle test is performed, and the first drive motor 211 can be stationary at this time. Therefore, the internal cooling device 3 can be tested for hot and cold cycles, so as to better simulate the actual temperature changes and stress conditions of the internal cooling device 3, thereby improving the judgment of the aging degree of the equipment and the ability to resist hot and cold cycle aging, and improving the test accuracy and effectiveness.

[0069] Furthermore, the first rotary joint 2114 is, for example, a rotary joint of an agricultural high-pressure spraying pipe. The first rotary joint 2114 is arranged in the bearing 2113 to achieve a hot and cold cycle test. When a heating test is required, the first rotary joint 2114 will not affect the rotation of the internal cooling device 3.

[0071] Specifically, the lifting assembly is used to place the internal cooling device 3 on the support assembly and tighten it, which can ensure the stable installation of the internal cooling device 3. The lifting assembly is arranged on the top of the heat preservation box 1, and the lifting assembly includes a cylinder 221, a mounting plate 223 and a top plate 222. The mounting plate 223 and the top plate 222 are rotatably connected, and the top plate 222 faces the internal cooling device 3. The cylinder 221 is arranged on the top outside the heat preservation box 1, and the cylinder rod passes through the heat preservation box 1 and is connected to the mounting plate 223. The cylinder 221 controls the mounting plate 223 and the top plate 222 to move up and down, which can tighten the internal cooling device 3 and further limit the internal cooling device 3. When the internal cooling device 3 rotates, the top plate 222 rotates relative to the mounting plate 223, thereby ensuring the stable rotation of the internal water-cooled device. A through hole is provided between the mounting plate 223 and the top plate 222, and a second rotary joint 412 is provided in the through hole. A bearing 2113 can be provided between the second rotary joint 412 and the mounting plate 223 and the top plate 222, so as to ensure that the mounting plate 223 and the top plate 222 rotate relative to the second rotary joint 412. In this way, when the internal cooling device 3 rotates, the second rotary joint 412 does not affect the rotation of the device.

[0072] Example 1

The cooling liquid inlet 31 and the cooling liquid outlet 32 ​​of the internal cooling device 3 are blocked by parts, and then the internal cooling device 3 is placed on the support frame 212 in the thermal insulation box 1, and the first motor is driven. The first motor drives the two clamping rods to clamp the internal cooling device 3, and then the door 12 of the thermal insulation box 1 is closed. When performing a heating test, the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are energized, and the second motor is driven. The second electric drive supports the frame 212 to rotate, so that the induction coil 5 in the internal cooling device 3 floats in the cooling liquid, thereby heating the cooling liquid and realizing the heating test. If the cooling test is realized, the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 can be powered off to restore the cooling of the cooling liquid.

[0074] Example 2

The second motor drives the support frame 212 to rotate, so that the induction coil 5 in the internal cooling device 3 floats in the coolant, thereby heating the coolant and realizing the heating test. If a cooling test is to be realized, the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 can be de-energized, and the coolant inlet and outlet of the internal cooling device 3 are connected to the refrigeration system 4, so that the coolant of the internal cooling device 3 is refrigerated, and a cooling test is realized. Thus, a hot and cold cycle test is realized.

[0076] Example 3

[0077] like Figure 1-3As shown in Figures 5-6, the cavity of the internal cooling device 3 to be tested is filled with coolant, and the induction coil 5 is placed.

When performing a heating test, the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are energized, and the second motor is driven. The second motor drives the support frame 212 to rotate, so that the induction coil 5 in the internal cooling device 3 floats in the coolant, thereby heating the coolant and realizing the heating test. If a cooling test is to be realized, the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 can be powered off, and the refrigeration system 4 in the insulation box 1 is turned on. The refrigeration pipeline 13 on the side wall of the insulation box 1 is refrigerated to realize external refrigeration of the internal cooling device and realize the cooling test. A hot and cold cycle test is realized.

When performing the heating test, the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 are energized, and the second motor is driven, and the second motor drives the support frame 212 to rotate, so that the induction coil 5 in the internal cooling device 3 floats in the coolant, thereby heating the coolant and realizing the heating test. If the cooling test is realized, the first electromagnetic induction coil 112 and the second electromagnetic induction coil 120 can be powered off, and the operation of all motors can be stopped, and the refrigeration system 4 can be turned on. The refrigeration system 4 circulates and refrigerates the coolant in the cavity of the internal cooling device 3, which can better play a refrigeration test. The hot and cold cycle test is realized.
