Description

Technical Field

[0001] This application belongs to the field of sheet metal manufacturing technology, specifically a wind tunnel sheet metal. Background Technology

[0002] Currently, sheet metal housings used as control boxes have one air inlet and one air outlet. Many components need to be installed inside the sheet metal housing, mainly including IGBT module slots, capacitor banks, motherboards, etc. In order to maximize space utilization, traditional sheet metal housings only have one air inlet and one air outlet, and the shape and size of the air inlet and air outlet are relatively small, resulting in extremely poor heat dissipation. This is because the air volume is small, and the area through which the air flows inside the sheet metal housing is insufficient, resulting in limited heat removal. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a wind tunnel sheet metal system. This system utilizes partitions and supports within the sheet metal housing, along with two air inlets and outlets on the side wall of the sheet metal housing. This design facilitates the installation of parts within the sheet metal housing and ensures that the sheet metal housing receives sufficient heat dissipation. It solves the problems of insufficient airflow area and insufficient air volume in current sheet metal housings, which lead to poor heat dissipation.

A plurality of supports are provided on the inner bottom surface of the sheet metal shell, with the length line of each support perpendicular to the right side wall of the sheet metal shell. A gap exists between the support and the inner side wall of the sheet metal shell, or a predetermined gap exists between the support and the partition.

[0006] Preferably, the support is a rib, the height of which is lower than the height of the partition, and there is a preset gap between the rib and the partition.

[0007] Preferably, the support is a rib, the height of which is lower than the height of the partition, and there is a preset gap between the rib and the sheet metal shell.

[0008] Preferably, the protrusions are provided on the left half of the inner bottom wall of the sheet metal shell, and a capacitor bank slot is provided on all the protrusions located between the partition and the front side wall of the sheet metal shell, with a preset gap between the bottom of the capacitor bank slot and the inner bottom wall of the sheet metal shell.

[0009] Preferably, all the protrusions located between the partition and the rear side wall of the sheet metal shell are provided with an IGBT module slot, and there is a preset gap between the bottom of the IGBT module slot and the inner bottom wall of the sheet metal shell.

[0011] Preferably, the protruding rib is provided with a through hole, and the axis of the through hole is perpendicular to the right side wall of the sheet metal shell.

[0012] Compared with the prior art, this application has the following beneficial effects:

[0013] This application adopts a method of setting up partitions and supports inside the sheet metal shell, along with two air inlets and outlets on the side wall of the sheet metal shell, to design a wind tunnel sheet metal.

[0019] like Figure 1-4As shown, a wind tunnel sheet metal structure includes a sheet metal shell 1. The sheet metal shell 1 has a bottom wall and four side walls that are sealed to each other. All four side walls are sealed to the bottom wall. A partition 2 is provided on the left half of the inner bottom wall of the sheet metal shell 1. The partition 2 is parallel to the front side wall of the sheet metal shell 1. A first air outlet 3 and a second air outlet 4 are provided on the right side wall of the sheet metal shell 1. The first air outlet 3 is located between the rear side wall of the sheet metal shell 1 and the partition 2. The second air outlet 4 is located between the front side wall of the sheet metal shell 1 and the partition 2. A first air inlet 5 corresponding to the first air outlet 3 and a second air inlet 6 corresponding to the second air outlet 4 are provided on the left side wall of the sheet metal shell 1. A plurality of supports are provided on the inner bottom surface of the sheet metal shell 1. The length line of the supports is perpendicular to the right side wall of the sheet metal shell 1. There is a gap between the supports and the inner side wall of the sheet metal shell 1 or a predetermined gap between the supports and the partition 2.

[0020] In this embodiment, in order to make full use of the internal space of the sheet metal shell 1, the left half of the inner bottom wall of the sheet metal shell 1 is equipped with an IGBT module 11 and a capacitor bank 12. The IGBT module is installed between the partition 2 and the rear side wall of the sheet metal shell 1, while the capacitor bank is installed between the partition 2 and the front side wall of the sheet metal shell 1. When setting it up, it is preferable that the first air inlet 5 and the first air outlet 3 are coaxial, and the second air inlet 6 and the second air outlet 4 are coaxial. The first air inlet 5 and the second air inlet 6 are located on both sides of the partition 2. When dissipating heat, the air entering at the first air inlet 5 leaves the sheet metal shell 1 from the first air outlet 3. The air entering at the first air inlet 5 is used to dissipate heat for the IGBT module 11, while the air entering at the second air inlet 6 is used to dissipate heat for the capacitor bank 12. The control board 13 is located on the right side wall of the sheet metal housing 1, between the first air outlet 3 and the second air outlet 4. This allows the air entering through the second air inlet 6 and the first air inlet 4 to simultaneously carry away the heat generated on the control board 13, thus improving heat dissipation efficiency. The support is designed so that the IGBT module 11 and capacitor bank 12 installed inside the sheet metal housing 1 form gaps with the inner bottom wall of the sheet metal housing 1. This allows the air entering the sheet metal housing 1 to make full contact with the IGBT module 11 and capacitor bank 12, thereby dissipating heat from them. The gap between the support and the inner side wall of the sheet metal housing 1, or the preset gap between the support and the partition 2, allows the air entering the sheet metal housing 1 to quickly exit through the first air outlet 3 or the second air outlet 4, further improving heat dissipation efficiency.

[0021] As a preferred embodiment, the support is a ridge 7, the height of which is lower than the height of the partition 2, and a predetermined gap exists between the ridge 7 and the partition 2. This arrangement of the ridge 7 allows it to have more contact surface with the IGBT module 11 or capacitor bank 12, resulting in more stable support.

[0022] As a preferred embodiment, the support is a rib 7, the height of which is lower than the height of the partition 2, and there is a preset gap between the rib 7 and the sheet metal shell 1.

[0023] As a preferred embodiment, the protrusions 7 are located on the left half of the inner bottom wall of the sheet metal shell 1. All the protrusions 7 located between the partition 2 and the front side wall of the sheet metal shell 1 share a common capacitor bank slot 8. A predetermined gap exists between the bottom of the capacitor bank slot 8 and the inner bottom wall of the sheet metal shell 1. This design of the capacitor bank slot 8 allows the capacitor bank 12 to be installed within it, facilitating installation and enabling preliminary positioning of the capacitor bank 12 before the positioning pins are used to position it. During manufacturing, it also facilitates placing the capacitor bank 12 into the sheet metal shell 1 as one workstation, and then positioning it using the positioning pins as the next workstation, thereby improving assembly efficiency.

[0024] As a preferred embodiment, all the protrusions 7 located between the partition 2 and the rear sidewall of the sheet metal shell 1 are provided with an IGBT module slot 9, and there is a preset gap between the bottom of the IGBT module slot 9 and the inner bottom wall of the sheet metal shell 1. The IGBT module slot 9 is provided to facilitate the installation of the IGBT module 11.

[0025] As a preferred embodiment, the height of the partition 2 is equal to the height of the side wall of the sheet metal shell 1. This arrangement allows the partition 2 to divide the left side of the sheet metal shell 1 into two halves, and also provides sufficient area on the partition 2 to install auxiliary parts.

[0026] As a preferred embodiment, the protruding rib 7 is provided with a through hole 10, the axis of which is perpendicular to the right side wall of the sheet metal shell 1. By providing the through hole 10, the protruding rib 17, while serving as a support, reduces its impact on airflow within the sheet metal shell 1 and minimizes its obstruction of heat dissipation.
