[0035] In response to the problems existing in the current technology, combined with Figure 1-6 A battery testing chassis includes a chassis shell 1 and a circuit board 2 disposed inside the chassis shell 1, wherein the circuit board 2 is electrically connected to an external battery through a connector 3.

[0036] The circuit boards 2 are configured as N, and are arranged in three layers. Each circuit board 2 is fixed by a single heat sink 5.

[0037] The heat sink 5 is configured with an inverted triangle shape, and the circuit board 2 is fixed inside the heat sink 5 with the inverted triangle shape.

[0038] The chassis shell 1 is fixedly provided with three fixing plates 6, and the three sets of circuit boards 2 and the three sets of heat sinks 5 are respectively set on the three fixing plates 6;

[0039] Three sets of cooling fans 7 are provided on one side wall of the chassis shell 1, wherein the cooling fans 7 correspond to the heat sink 5 so that the airflow generated by the cooling fans 7 when they are started can pass through the heat sink 5 of the U-shaped heat dissipation structure.

[0040] Specifically, by fixing the circuit board 2 to the heat sink 5 with the U-shaped heat dissipation structure, when the cooling fan 7 is turned on, the airflow of the cooling fan 7 passes through the surface of the heat sink 5 and the circuit board 2, effectively increasing the heat dissipation area and dissipating heat on both sides of the circuit board 2, resulting in better heat dissipation effect.

[0041] The circuit board 2 can be configured with multiple groups (multi-layers) of cooling fans 7 to provide individual cooling for each layer. Even if multiple circuit boards 2 are configured, heat dissipation can be effectively achieved.

[0042] In some specific embodiments, the heat sink 5 includes an inverted plate 8 and heat dissipation fins 9. The heat dissipation fins 9 are distributed on the outer sides of both ends of the inverted plate 8, and the heat dissipation fins 9 near the fixed plate 6 are abutted and fixed to the fixed plate 6.

[0043] Specifically, the arrangement of the convex plate 8 effectively increases the heat dissipation area of ​​the radiator 5, thereby further enhancing the heat dissipation effect of the area inside the convex plate 8. In addition, the heat dissipation fins 9 arranged at both ends of the convex plate 8 further increase the heat dissipation area and improve the heat dissipation effect.

[0044] In some specific embodiments, the upper and lower sidewalls of the inner side of the shaped plate 8 are provided with corresponding strip grooves 10, and the upper and lower ends of the circuit board 2 are respectively embedded in the two strip grooves 10.

[0045] Specifically, by setting a corresponding strip groove 10 on the inner side of the shaped plate 8, the circuit board 2 can be placed directly inside the strip groove 10 for direct contact, which can improve the heat dissipation effect of the circuit board 2 to a certain extent when the heat sink 5 dissipates heat. The circuit board 2 can also be further fixed in the strip groove 10 by glue or bolts.

[0046] In some specific embodiments, the inner sides of both ends of the shaped plate 8 are thickened, and a plurality of strip-shaped gaskets 11 and shaped gaskets 12 are provided on one side wall of the shaped plate 8. The shaped plate 8 is fixed on the fixing plate 6 by pressing the strip-shaped gaskets 11 through the shaped gaskets 12 and the shaped plate 8 in sequence with bolts.

[0047] Specifically, to facilitate fixing the C-shaped plate 8 to the fixing plate 6, multiple strip-shaped gaskets 11 are used to increase the fixing area of ​​the C-shaped plate 8 and improve the fixing stability. The C-shaped gaskets 12 are used to squeeze the strip-shaped gaskets 11 to fix the C-shaped plate 8.

[0048] In some specific embodiments, the plurality of heat dissipation fins 9 are arranged in parallel and face the cooling fan 7.

[0049] Specifically, this facilitates more even heat dissipation among multiple heat dissipation fins 9 when the cooling fan 7 starts.

[0050] In some specific embodiments, the upper surface of the chassis shell 1 is provided with an inclined surface, the connector 3 is disposed on the inclined surface, and the inclined surface is also provided with a plurality of first heat dissipation holes 13, which can correspond to the position of the uppermost circuit board 2.

[0051] Specifically, during heat dissipation, gas flows through the first heat dissipation hole 13. Since the connector 3 is also located on the inclined surface, the gas flow speed at the connector 3 location is increased, thereby improving the heat dissipation effect of the connector 3.

[0052] In some specific embodiments, a detachable baffle 14 is provided on one side of the chassis shell 1, and a second heat dissipation hole 15 is provided on the baffle 14. The second heat dissipation hole 15 can correspond to the circuit board 2 except for the uppermost circuit board 2.

[0053] Specifically, since the circuit board 2 is divided into three layers, the second heat dissipation hole 15 on the baffle 14 allows air to circulate through the lower two layers of the circuit board 2, thereby improving heat dissipation.

[0054] In some specific embodiments, the two uppermost fixing plates 6 are connected to the chassis shell 1 at the end near the cooling fan 7 via a support plate, and are alternately arranged with multiple sets of cooling fans 7.

[0055] In some specific embodiments, a control unit 16 is also included, which is disposed on the two uppermost fixing plates 6 and between the cooling fan 7 and the heat sink 5.

[0056] Specifically, a control unit 16 (which is an existing component, such as a controller, microcontroller, or PLC) is installed on the support plate. When the circuit board 2 is cooled, the control unit 16 can also be cooled.

[0057] In some specific embodiments, the two sides of the fixing plate 6 are fixed to the outer casing 1 of the chassis by angle irons 16, so as to securely fix the fixing plate 6.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
