Description

Technical Field

[0001] This utility model relates to the field of new energy equipment technology, specifically to a new energy testing cabinet. Background Technology

[0002] New energy generally refers to renewable and clean energy, as opposed to traditional energy sources such as coal, oil, and natural gas. Also known as unconventional energy, it refers to various energy forms other than traditional energy sources. New energy includes solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy, characterized by being green and low-carbon, without the risk of resource depletion, and with declining energy prices, making it a key area for future energy development. Currently, new energy is receiving increasing attention, and various new energy instruments and equipment are emerging in large numbers. Common examples include batteries, battery management systems, inverters, MPPT controllers, and on-board computer (OBC) systems. These devices need to withstand different scenarios during use (such as high temperature, low temperature, high pressure, humidity, dryness, or long-term high-load operation). During the production process of new energy equipment, functional testing is usually required to determine the equipment's operating status under different conditions and ensure that the product meets design requirements. Currently, when testing new energy equipment, it is usually placed inside a cabinet with a fixed shelf. During testing, the equipment is placed on the shelf. However, when conducting high-temperature tests, the cabinet is usually sealed, and the heat generated by the equipment itself is used to raise the temperature inside the cabinet. This method is time-consuming, inefficient, and difficult to control the temperature. Utility Model Content

Detailed Implementation

[0025] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1 to 6 This utility model provides a new energy testing cabinet, including a cabinet body 1, a bottom frame 2 disposed at the bottom of the cabinet body 1, and several uprights 3 vertically disposed on the bottom frame 2. The intervals between adjacent uprights 3 are equal, and a support component 4 for placing the product to be tested is disposed between two adjacent uprights 3. The number of uprights 3 can be set according to actual needs. In this embodiment, three uprights 3 are provided (i.e., forming two intervals for accommodating the support component 4). Several heating fan components 5 are disposed on the rear inner wall of the cabinet body 1, and at least one heating fan component 5 is disposed at the interval between adjacent uprights 3. The heating fan components 5 can heat the air inside the cabinet body 1, thereby increasing the internal temperature of the cabinet body 1, so that the new energy equipment under test can be tested at a preset temperature value.

[0028] like Figure 5As shown, the heating fan assembly 5 includes a first fan 51, a heating element 52 disposed on the first fan 51, and a housing 53 disposed on the first fan 51, the housing 53 surrounding the heating element 52. The heating element 52 includes an outer frame 521 and a heating element 522 disposed inside the outer frame 521, the outer frame 521 being disposed on the first fan 51. In this embodiment, the heating fan assembly 5 is positioned near the lower side. The first fan 51 blows air from the bottom of the cabinet 1 toward the heating element 52. The air passes through the heating element 52 and is heated. The heated air expands in volume and decreases in density. Under the combined action of buoyancy and the dynamic pressure of the first fan 51, it quickly rises to the top of the cabinet 1, achieving rapid heating of the interior of the cabinet 1 and bringing the internal temperature to the set value that meets the test conditions.

[0029] In this embodiment, multiple heating elements 52 are arranged side by side, and each heating element 522 is serrated. The serrated heating element 522 significantly increases the contact area with air, improving the overall heat exchange efficiency and shortening the heating time.

[0030] The bottom surface of the cabinet 1 is provided with several rollers 11 and several support feet 12. The support feet 12 are height adjustable. After the cabinet 1 is moved to a predetermined position using the rollers 11, the height of the support feet 12 can be adjusted so that the rollers 11 of the cabinet 1 are off the ground, thus preventing the cabinet 1 from moving.

[0031] The support assembly 4 includes a symmetrically arranged first support frame 41 and a second support frame 42, which are respectively mounted on two adjacent uprights 3. In this embodiment, both the first support frame 41 and the second support frame 42 have L-shaped cross-sections, allowing for support of the new energy equipment from both sides when it is placed. Multiple sets of the support assembly 4 can be arranged vertically to facilitate the simultaneous placement of multiple new energy devices.

[0032] The upright frame 3 includes a support frame 31 and at least two connecting rods 32 vertically disposed on the support frame 31. The sidewalls of the connecting rods 32 are evenly provided with a plurality of first connecting holes 33 along the vertical direction. The first support frame and the second support frame are disposed on the connecting rods of the upright frame. In this embodiment, the two connecting rods 32 correspond to the front and rear ends of the first support frame 41 and the second support frame 42, respectively, ensuring the stability of the connection.

[0033] Both the first support frame 41 and the second support frame 42 are provided with waist-shaped holes that match the first connecting hole 33. Fasteners pass through the waist-shaped holes to connect the first support frame 41 / second support frame 42 to the corresponding first connecting hole 33. One or more waist-shaped holes can be provided to facilitate adjustment of the vertical position (i.e., adjusting the distance between two adjacent support components 4) or the front-back position according to different new energy equipment.

[0034] The new energy testing cabinet also includes drawers 7, which are connected to the support component 4. The number of drawers 7 can be set according to specific needs, and drawers 7 can be used to place new energy equipment whose size is smaller than the support range of the support component 4.

[0035] The front side of the upright frame 3 is also provided with a limiting strip 8 that cooperates with the drawer 7. The limiting strip 8 is arranged vertically and has several second connecting holes 81 arranged vertically on it. The limiting strip 8 is located on the front side of the support frame 31 of the upright frame 3, so as to... Figure 2 Taking the left side of the interval as an example, this interval is defined as the placement area. The limiting strip 8 is provided on both the left and right sides of the placement area, so that the left and right sides of the drawer 7 can be limited. The second connecting hole 81 is used to fix the drawer 7. In this embodiment, the front sides of the drawer 7 are provided with connecting parts, and the connecting parts are also provided with waist-shaped holes. The drawer 7 can be locked to the limiting strip 8 by fasteners, so as to prevent the drawer 7 from moving back and forth.

[0036] Second fans 6 are installed on the rear wall of the cabinet 1 near both the top and bottom. In this embodiment, two second fans 6 are installed near the bottom, and three second fans 6 are installed near the top. The lower fans are for air intake, and the upper fans are for air exhaust. Of course, the number and position of the fans are not limited in specific implementations; for example, the fans near the bottom can also be installed on the bottom surface of the cabinet 1. During high-temperature testing, the second fans 6 can introduce low-temperature external air and exhaust high-temperature internal air to quickly regulate the internal temperature of the cabinet 1, preventing it from becoming too high and ensuring that the internal temperature of the cabinet 1 meets the testing requirements. During other tests, the second fans 6 can quickly dissipate heat from the inside of the cabinet. In specific implementations, multiple temperature sensors can also be installed in different areas inside the cabinet 1 to monitor the internal temperature and adjust the heating fan assembly 5 or the second fans 6 in a timely manner according to temperature changes to achieve heating or cooling.

[0037] The cabinet 1 is also provided with a wiring port 13 near the bottom of the rear wall. The cabinet 1 is also provided with adapter board, control circuit board and power adapter and other devices required in the testing process. The new energy equipment under test can be connected to external testing devices through the connecting wire and adapter board.

[0038] The cabinet 1 has ventilation holes 14 on its side wall. In practice, a sliding plate is also provided at the ventilation holes 14. The sliding plate can close the ventilation holes 14 during high-temperature testing to reduce internal heat dissipation.

[0039] Example 2

[0040] This utility model provides a new energy testing cabinet, comprising a cabinet body 1, a bottom frame 2 disposed at the bottom of the cabinet body 1, and several uprights 3 vertically disposed on the bottom frame 2. The spacing between adjacent uprights 3 is equal, and a support assembly 4 for placing the product to be tested is disposed between two adjacent uprights 3. Several heating fan assemblies 5 are disposed on the rear inner wall of the cabinet body 1, with at least one heating fan assembly 5 corresponding to the spacing between adjacent uprights 3. The heating fan assemblies 5 can heat the air inside the cabinet body 1, thereby increasing the internal temperature of the cabinet body 1, allowing the new energy equipment under test to be tested at a preset temperature value.

[0041] The heating fan assembly 5 includes a first fan 51, a heating element 52 disposed on the first fan 51, and a housing 53 disposed on the first fan 51, the housing 53 enclosing the heating element 52. The heating element 52 includes an outer frame 521 and a heating element 522 disposed inside the outer frame 521, the outer frame 521 being disposed on the first fan 51. In this embodiment, the heating fan assembly 5 is positioned near the lower side. The first fan 51 blows air from the bottom of the cabinet 1 toward the heating element 52. The air passes through the heating element 52 and is heated. The heated air expands in volume and decreases in density. Under the combined action of buoyancy and dynamic pressure of the first fan 51, it quickly rises to the top of the cabinet 1, achieving rapid heating of the interior of the cabinet 1 and bringing the internal temperature to the set value that meets the test conditions.

[0042] In this embodiment, multiple heating elements 52 are arranged side by side. In this embodiment, the heating element 522 is S-shaped instead of serrated. This shape reduces the contact area with air, but can appropriately increase the space for air circulation and increase the circulation volume per unit time.

[0043] The bottom surface of the cabinet 1 is provided with several rollers 11 and several support feet 12. The support feet 12 are height adjustable. After the cabinet 1 is moved to a predetermined position using the rollers 11, the height of the support feet 12 can be adjusted so that the rollers 11 of the cabinet 1 are off the ground, thus preventing the cabinet 1 from moving.

[0044] The support assembly 4 includes a symmetrically arranged first support frame 41 and a second support frame 42, which are respectively mounted on two adjacent uprights 3. In this embodiment, both the first support frame 41 and the second support frame 42 have L-shaped cross-sections, allowing for support of the new energy equipment from both sides when it is placed. Multiple sets of the support assembly 4 can be arranged vertically to facilitate the simultaneous placement of multiple new energy devices.

[0045] The upright frame 3 includes a support frame 31 and at least two connecting rods 32 vertically disposed on the support frame 31. The sidewalls of the connecting rods 32 are evenly provided with a plurality of first connecting holes 33 along the vertical direction. The first support frame and the second support frame are disposed on the connecting rods of the upright frame. In this embodiment, the two connecting rods 32 correspond to the front and rear ends of the first support frame 41 and the second support frame 42, respectively, ensuring the stability of the connection.

[0046] Both the first support frame 41 and the second support frame 42 are provided with waist-shaped holes that match the first connecting hole 33. Fasteners pass through the waist-shaped holes to connect the first support frame 41 / second support frame 42 to the corresponding first connecting hole 33. One or more waist-shaped holes can be provided to facilitate adjustment of the vertical position (i.e., adjusting the distance between two adjacent support components 4) or the front-back position according to different new energy equipment.

[0047] The new energy testing cabinet also includes drawers 7, which are connected to the support component 4. The number of drawers 7 can be set according to specific needs, and drawers 7 can be used to place new energy equipment whose size is smaller than the support range of the support component 4.

[0048] The front side of the upright frame 3 is also provided with a limiting strip 8 that cooperates with the drawer 7. The limiting strip 8 is arranged vertically and has several second connecting holes 81 arranged vertically on it. The limiting strip 8 is located on the front side of the support frame 31 of the upright frame 3, so as to... Figure 2 Taking the left side of the interval as an example, this interval is defined as the placement area. The limiting strip 8 is provided on both the left and right sides of the placement area, so that the left and right sides of the drawer 7 can be limited. The second connecting hole 81 is used to fix the drawer 7. In this embodiment, the front sides of the drawer 7 are provided with connecting parts, and the connecting parts are also provided with waist-shaped holes. The drawer 7 can be locked to the limiting strip 8 by fasteners, so as to prevent the drawer 7 from moving back and forth.

[0049] Second fans 6 are installed on the rear wall of the cabinet 1 near both the top and bottom. In this embodiment, two second fans 6 are installed near the bottom, and three second fans 6 are installed near the top. The lower fans are for air intake, and the upper fans are for air exhaust. Of course, the number and position of the fans are not limited in specific implementations; for example, the fans near the bottom can also be installed on the bottom surface of the cabinet 1. During high-temperature testing, the second fans 6 can introduce low-temperature external air and exhaust high-temperature internal air to quickly regulate the internal temperature of the cabinet 1, preventing it from becoming too high and ensuring that the internal temperature of the cabinet 1 meets the testing requirements. During other tests, the second fans 6 can quickly dissipate heat from the inside of the cabinet. In specific implementations, multiple temperature sensors can also be installed in different areas inside the cabinet 1 to monitor the internal temperature and adjust the heating fan assembly 5 or the second fans 6 in a timely manner according to temperature changes to achieve heating or cooling.

[0050] The cabinet 1 is also provided with a wiring port 13 near the bottom of the rear wall. The cabinet 1 is also provided with adapter board, control circuit board and power adapter and other devices required in the testing process. The new energy equipment under test can be connected to external testing devices through the connecting wire and adapter board.

[0051] The cabinet 1 has ventilation holes 14 on its side wall. In practice, a sliding plate is also provided at the ventilation holes 14. The sliding plate can close the ventilation holes 14 during high-temperature testing to reduce internal heat dissipation.
