TECHNICAL FIELD

[0001] The utility model relates to the technical field of energy storage converter test, concretely to a kind of temperature change adaptability testing device of energy storage converter. BACKGROUND

[0002] Energy storage converter is a kind of electronic device for converting the electric energy stored in energy storage system into usable electric energy. It can adjust and convert current and voltage as needed to realize the effective connection of energy storage system and power grid or other energy systems. Temperature change adaptability testing device is mainly used to evaluate the working performance and stability of energy storage converter under different temperature conditions. Since the working state of energy storage converter may change under different ambient temperatures, it is very important to test its temperature change adaptability to ensure the reliability and safety of the converter under extreme environments such as high temperature and low temperature.

[0003] At present, most energy storage converters are tested by test box, which usually uses heating sheet or heating device for high temperature test, so there are the following shortcomings: the heat inside the test box may not be evenly distributed around the energy storage converter when in use, which reduces the accuracy and reliability of test results. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of temperature change adaptability testing device of energy storage converter to solve the problem that the heat inside the test box may not be evenly distributed around the energy storage converter when in use, which reduces the accuracy and reliability of test results.

[0005] To achieve the above utility model purpose, the utility model adopts the following technical scheme: a kind of temperature change adaptability testing device of energy storage converter, including box door, the box door is rotatably connected on the outer wall front side of test box by hinge, the inside of test box is fixed with heat conduction plate, the bottom surface of heat conduction plate is fixed with heating sheet, the outer wall left side and right side of test box are respectively fixed with hot air blower, two hot air blowers are respectively communicated with test box and are fixed with air supply pipe, the inner wall left side and right side of test box are respectively detachably provided with flow guide box, two flow guide boxes are respectively provided with air inlet on the outside, two flow guide boxes are respectively provided with air outlet on the outside, the outer wall back side of left flow guide box and the outer wall front side of right flow guide box are respectively fixed with arc flow guide plate.

[0006] Preferably, two screw grooves are respectively provided on the inner wall left side and right side of the test box, two mounting plates are respectively fixed on the top surface and bottom surface of the two flow guide boxes, a screw hole is respectively provided on one side of the two mounting plates, a bolt is respectively screwed into the two screw holes, and the threaded end of the two bolts is respectively screwed into the two screw grooves.

[0007] Preferably, a connecting frame is fixed to the inner top surface of the test chamber, and a cooling plate is fixed inside the connecting frame.

[0008] Preferably, a cooling fan is fixed to the top surface of the test chamber, and a connecting pipe is fixed between the cooling fan and the test chamber.

[0009] Preferably, an observation port is provided on the front side of the door, and tempered glass is fixed inside the observation port.

[0010] Preferably, a sealing ring is fixed to the rear side of the door.

[0011] Compared with existing technologies, the temperature adaptability testing device for an energy storage converter that adopts the above technical solution has the following advantages:

[0012] First, during use, the operator opens the chamber door, places the energy storage converter to be tested on the heat-conducting plate, and then closes the door to ensure the sealing of the testing environment. The heating element is then activated, and heat is quickly and evenly transferred to the top of the converter via the heat-conducting plate, simulating a high-temperature environment to test the converter's operation under high-temperature conditions. Simultaneously, two hot air blowers are activated, and hot air is delivered into the air distribution box through the air supply pipes. The hot air flows evenly out from the air outlets and along the curved air distribution plate, forming a circulating hot air path to ensure that the heat inside the test chamber is evenly distributed around the energy storage converter. The combined use of the heat-conducting plate, heating element, hot air blowers, air supply pipes, air distribution box, and curved air distribution plate facilitates the circulation of heat inside the test chamber, ensuring even heat distribution around the energy storage converter and improving the accuracy and reliability of the test results.

[0013] Second, during use, the use of threaded grooves, mounting plates, and bolts facilitates the disassembly and assembly of the flow guide box and arc-shaped flow guide plate, simplifying the operation process and improving the maintainability and flexibility of the equipment. The use of the connecting frame in conjunction with the cooling elements helps to rapidly reduce the internal temperature of the test chamber, simulating a low-temperature environment to test the operating status of the energy storage converter under low-temperature conditions. This allows the testing device to cover a wider temperature range and meet more diverse testing needs.

[0014] Third, during use, the air cooler delivers cool air into the test chamber through connecting pipes, working synergistically with the cooling coils to simulate a wind-cooled environment. This not only enhances the realism of the test environment but also improves the comprehensiveness of the test. The observation port, combined with tempered glass, provides a clear viewing window for personnel to observe the changes in the energy storage converter during the test in real time. When the chamber door is closed, the sealing ring fits tightly against the frame of the test chamber, effectively preventing heat leakage and the intrusion of cold air from the outside. This not only ensures the stability and consistency of the test environment but also improves the accuracy and reliability of the test. Attached Figure Description

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, a temperature adaptability testing device for an energy storage converter includes a door 1, which is rotatably connected to the front of the outer wall of a test chamber 2 via a hinge. A heat-conducting plate 3 is fixed inside the test chamber 2, and a heating element 4 is fixed to the bottom surface of the heat-conducting plate 3. Hot air blowers 5 are fixed to the left and right sides of the outer wall of the test chamber 2, and air supply pipes 6 are fixedly connected to the two hot air blowers 5 and the test chamber 2, respectively. Air guide boxes 7 are detachably provided on the left and right sides of the inner wall of the test chamber 2, and air inlets 8 and air outlets 9 are respectively opened on the outer sides of the two air guide boxes 7. Arc-shaped air guide plates 10 are fixed to the rear side of the outer wall of the left air guide box 7 and the front side of the outer wall of the right air guide box 7, respectively.

[0022] During use, the staff first opens the chamber door 1, then places the energy storage converter to be tested on the heat conduction plate 3, and then closes the chamber door 1 to ensure the sealing of the test environment. At this time, the heating element 4 is activated, and the heat is quickly and evenly transferred to the top of it through the heat conduction plate 3 to simulate a high-temperature environment to test the working state of the energy storage converter under high-temperature conditions. At the same time, the staff activates two hot air blowers 5, and the hot air is sent into the interior of the guide box 7 through the air supply pipe 6. The hot air flows out evenly from the air outlet 9 and flows along the arc-shaped guide plate 10 to form a circulating hot air path, ensuring that the heat inside the test chamber 2 is evenly distributed around the energy storage converter.

[0023] The combined use of heat-conducting plate 3, heating element 4, hot air blower 5, air supply pipe 6, flow guide box 7, and arc-shaped flow guide plate 10 facilitates the circulation of heat inside the test chamber 2, enabling the heat to be evenly distributed around the energy storage converter, thereby improving the accuracy and reliability of the test results.

[0024] like Figures 1-4 As shown, two threaded grooves 11 are respectively opened on the left and right sides of the inner wall of the test box 2. Mounting plates 12 are fixed on the top and bottom surfaces of the two flow guide boxes 7 respectively. Threaded holes 13 are opened on one side of the two mounting plates 12 respectively. Bolts 14 are threadedly connected in the two threaded holes 13 respectively. The threaded ends of the two bolts 14 are respectively connected to the internal threads of the two threaded grooves 11.

[0025] In use, the use of the threaded groove 11, mounting plate 12 and bolt 14 makes it easy for staff to disassemble and assemble the flow guide box 7 and the arc-shaped flow guide plate 10, which not only simplifies the operation process, but also improves the maintainability and flexibility of the equipment.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a connecting frame 15 is fixed on the top surface inside the test chamber 2, a cooling chip 16 is fixed inside the connecting frame 15, a cooler 17 is fixed on the top surface of the test chamber 2, and a connecting pipe 18 is fixed between the cooler 17 and the test chamber 2.

[0027] In use, the connection frame 15, in conjunction with the cooling element 16, facilitates the rapid reduction of the internal temperature of the test chamber 2, simulating a low-temperature environment to test the operating status of the energy storage converter under low-temperature conditions. This allows the test device to cover a wider temperature range and meet more diverse testing needs. The air cooler 17 delivers cold air into the test chamber 2 through the connecting pipe 18, working synergistically with the cooling element 16 to simulate a wind-cooled environment. This not only enhances the realism of the test environment but also improves the comprehensiveness of the test.

[0028] like Figure 1 and Figure 2As shown, an observation port 19 is provided on the front side of the door 1, and a tempered glass 20 is fixed inside the observation port 19. A sealing ring 21 is fixed on the rear side of the door 1.

[0029] During use, the observation port 19, in conjunction with the tempered glass 20, provides a clear viewing window for personnel, enabling real-time observation of the changes in the energy storage converter during the testing process. When the chamber door 1 is closed, the sealing ring 21 fits tightly against the frame of the test chamber 2, effectively preventing heat leakage and the intrusion of cold air from the outside. This not only ensures the stability and consistency of the testing environment but also improves the accuracy and reliability of the test.
