Description

Technical Field

[0001] The utility model relates to the field of test platforms, in particular to an airway temperature rise simulation test platform. Background Art

[0002] Air ducts are used in the design and manufacture of some transformer cores and motor cores to provide air cooling. Since air ducts are in various forms, have diverse arrangements and distributions, and have different application environments (such as natural cooling and forced air cooling), the current design of air ducts is mostly based on mature application models and relies on the experience of engineers, making it difficult to directly provide the optimal solution for air duct design. After the air duct is designed, a temperature rise test is required to verify whether it meets the performance requirements.

[0003] The existing temperature rise test is to assemble the finished product according to the design plan and then conduct the temperature rise test. Its manufacturing cost and test cost are high and the efficiency is low. Therefore, it is necessary to design a test platform simulating the airway to test the airway heat dissipation. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a simulated airway temperature rise experimental platform to solve one or more problems in the prior art.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A simulated airway temperature rise experimental platform comprises a mounting frame, a simulation component and a fan, wherein the simulation component comprises a heating plate, a simulation part and a connecting part, wherein there are two heating plates, the simulation part is located between the two heating plates, the connecting part fixes the heating plate and the simulation part together and is detachably connected to the mounting frame, an airway is opened in the simulation part and passes through the upper and lower ends of the simulation part, the fan is located below the simulation component and the air outlet of the fan is aligned with the airway opening.

[0007] Through the above technical solution, the heating plate can be connected to an external power supply to simulate heat generation. The simulation part and the heating plate are detachably connected. By replacing different simulation components, heat dissipation tests can be carried out on different airway forms, arrangement distributions and structural parameters. Setting a fan can realize the function of simulating a forced air cooling environment, thereby completing the airway heat dissipation test comprehensively and at low cost.

[0008] Preferably, the connecting member comprises a screw and two clamps, the two clamps are respectively abutted against opposite sides of the two heating plates and are connected together by the screw, and both ends of the clamps are detachably mounted on the mounting frame.

[0009] Through the above technical solution, when it is necessary to test different airways, only the simulation parts need to be replaced without replacing the connecting parts and the heating plate, thereby further reducing the cost of the test.

[0010] Preferably, the mounting frame is provided with a plurality of straight slots for mounting the clamps, the length direction of the straight slots is parallel to the length direction of the screws for connecting the clamps, and the clamps are detachably connected to the mounting frame by bolts and the bolts pass through the corresponding straight slots.

[0011] Through the above technical solution, simulation components of different widths can be installed more flexibly to meet the test requirements of airways with a larger width range. When the fan is difficult to adjust its position, the simulation component can be moved to make one end of the airway face the air outlet of the fan.

[0012] Preferably, there are multiple connecting members, and the multiple connecting members are sequentially connected to the heating plate along the vertical direction, and any one of the connecting members can be detachably connected to the mounting frame.

[0013] Through the above technical solution, multiple connecting parts can enhance the clamping and fixing effect of the simulation component, reduce the occurrence of gaps between the heating plate and the simulation part in the simulation component, and reduce the impact on the heat dissipation test.

[0014] Preferably, it further comprises two support plates corresponding to the clamps one by one, wherein one end of the support plate is fixed on the clamp, and the other end of the support plate is provided with a bending portion, and the bending portion is located directly below the heating plate attached to the corresponding clamp.

[0015] Through the above technical solution, since the connector fixes the simulation component by clamping, and the simulation component has a large weight, the simulation component may slip. The support plate can support the sliding simulation component and reduce damage to the platform equipment.

[0016] Preferably, the mounting frame comprises an upper support plate and a lower support plate, the upper support plate is slidably arranged on the lower support plate along a vertical direction, the upper support plate and the lower support plate are fixed together by a locking member, and the connecting member is installed on the upper support plate.

[0017] Through the above technical scheme, the adjustability of the air duct height is achieved according to the change of the installation position of the upper support plate on the lower support plate. On the one hand, it can meet the installation of multiple models of fans and realize the function of simulating forced air cooling environment. On the other hand, it can also study the influence of the fan outlet distance on the air duct heat dissipation.

[0018] Compared with the prior art, the beneficial technical effects of the utility model are as follows: through the experimental platform, the heat dissipation of the airway under multiple working conditions can be simulated, the temperature and flow rate data of the characteristic points can be obtained, and the influence of the airway structure size, material selection and distribution arrangement on the heat dissipation effect can be analyzed, which is helpful for the iterative optimization of the airway design scheme and provides data support for the standardization of airway design.

DETAILED DESCRIPTION

[0022] A simulated airway temperature rise experimental platform, see Figure 1 , including a mounting frame, a simulation component 3 and a fan 4. Among them, the mounting frame includes an upper support plate 1 and a lower support plate 2. The lower support plate 2 is provided with a support leg 21, and the lower support plate 2 is supported on the ground by the support leg 21. The upper support plate 1 is located at one end of the lower support plate 2 away from the support leg 21, and the upper support plate 1 is slidably arranged on the end of the lower support plate 2 along the vertical direction. The upper support plate 1 and the lower support plate 2 are fixed together by a locking member. The simulation component 3 is detachably mounted on the upper support plate 1, and the fan 4 is located directly below the simulation component 3 and placed on the ground, and the air outlet of the fan 4 is vertically upward to align with the simulation component 3. By adjusting the fixed position of the upper support plate 1 on the lower support plate 2, the distance from the simulation component 3 to the ground can be changed to provide placement space for fans 4 of different models.

[0023] See also Figure 1 , Figure 2 , the simulation component 3 includes a heating plate 31, a simulation part 32 and a connecting part 33. There are two heating plates 31, and the simulation part 32 is located between the two heating plates 31. An air duct running through the upper and lower ends of the simulation part 32 is opened in the simulation part 32. The connecting part 33 connects the two heating plates 31 and the simulation part 32 located in the middle of the heating plates 31 together so that the heating plates 31 squeeze the simulation part 32. In addition, the connecting part 33 is detachably fixed to the upper support plate 1. When the connecting part 33 is fixed to the upper support plate 1, the air duct is vertically arranged, and the air outlet of the fan 4 is aligned with the air duct opening.

[0024] The connecting member 33 includes a screw 332 and two clamps 331. The two clamps 331 are respectively abutted on the opposite sides of the two heating plates 31 and connected together by the screw 332. Both ends of the clamps 331 can be detachably mounted on the mounting frame. A plurality of straight slots 11 for mounting the clamps 331 are provided on the top of the upper support plate 1. The length direction of the straight slots 11 is parallel to the length direction of the screw 332 for connecting the clamps 331. The clamps 331 are detachably connected to the mounting frame by bolts and the bolts pass through the corresponding straight slots 11. The upper support plate 1 also includes two support plates 5 corresponding to the clamps 331. One end of the support plate 5 is fixed on the clamp 331. The other end of the support plate 5 is provided with a bending portion 51. The bending portion 51 is located directly below the heating plate 31 abutting against the corresponding clamp 331.

[0025] There are multiple connecting members 33, and the multiple connecting members 33 are sequentially connected to the heating plate 31 along the vertical direction, and any connecting member 33 is detachably connected to the mounting frame. In this embodiment, there are three connecting members 33, and the three connecting members 33 are respectively fixed to the top, middle and bottom positions of the heating plate 31, and the connecting member 33 in the middle position of the heating plate 31 is fixed to the upper support plate 1.

[0026] The simulation part 32 includes two layers of airway surface medium and a plurality of stays. The airway surface medium is a plate selected according to the test object. For example, if the transformer core is tested, the airway surface medium is a silicon steel sheet used to constitute the transformer core. The stay is located between the two layers of airway surface medium and isolates the required airway between the two layers of airway surface medium. In addition, in order to facilitate the measurement of temperature, a plurality of thermocouples are pre-embedded by welding on the side of the airway surface medium facing the stay.

[0027] The manufacturing process of the entire simulation component 3 is as follows: place the clamp 331 on one side on the bottom layer, lay a layer of insulation on it, and then place the heating plate 31 on the insulation layer, and the insulation layer wraps the upper and lower end surfaces and outer surface of the heating plate 31. After evenly applying thermal grease on the inner side of the heating plate 31, a layer of airway surface medium is affixed, and then the airway position is divided on the airway surface medium. And according to the divided position, the support bar is fixed to the airway surface medium by gluing or other adhesives. Another layer of airway surface medium is placed on the formed airway, and after evenly applying thermal grease, another heating plate 31 is pressed on, and then a layer of insulation is laid on the heating plate 31. Finally, the clamp 331 and the screw 332 are used to connect and fix the simulation component 3 as a whole.

[0028] Working principle: According to the test parameter requirements, adjust the relative positions of the upper support plate 1 and the lower support plate 2 and fix them with fixing pins. Align the screw hole of the clamp 331 in the middle of the simulation component 3 with the straight slot 11 of the upper support plate 1, and then tighten it with bolts. Then install the support plate 5 to the clamp 331 connected to the upper support plate 1 with bolts to complete the construction of the experimental platform. After the installation is completed, the heating plate 31 is connected to an external power supply to simulate the temperature rise of the device. The above steps can be completed under natural convection conditions. For forced convection conditions, the fan 4 at the bottom of the simulation component 3 must be turned on. The temperature is read through a thermocouple, and the wind speed at different points is measured using an external anemometer probe inserted into the air duct. After the test is completed, when disassembling, you only need to remove the clamp 331, replace the simulation component 32, and then repeat the above steps to carry out the next set of tests.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
