Description

Technical Field

[0001] This utility model relates to the field of air-cooled heat dissipation technology, and in particular to a frequency converter for new energy vehicles. Background Technology

[0002] Currently, various electrical devices or units are equipped with control boards to regulate their operation. For example, in a multi-functional hot water unit, a control board is required to control and drive the various components. When the control board is operating, its numerous electronic components continuously generate heat. When the ambient temperature is high, this heat is highly detrimental to the normal and stable operation of the control board and the entire device or unit; for high-power equipment, the negative effects of heat generation are particularly pronounced.

[0003] Existing technologies mainly use two methods for heat dissipation: air cooling and water cooling. Air cooling has lower cost, better applicability, and is widely used in practice. However, it has poor heat dissipation effect and low efficiency in removing heat from inside the inverter housing. Furthermore, it is troublesome to clean and disassemble the heat sink later. Utility Model Content

A front cover plate, a rear cover plate, and side panels are respectively arranged below the mounting plate. An air inlet groove and mounting holes are respectively formed on the surface of the front cover plate. An exhaust groove is formed on the surface of the rear cover plate. Two side panels are respectively located on both sides of the mounting plate. Heat dissipation grooves and mounting slots are respectively formed on the surface of the side panels. A mounting platform is provided on the surface of the side panels. A pin post and heat sink are provided at the bottom of the mounting plate.

[0006] Preferably, the heat sink is located on the axis of the mounting plate, the mounting box is located on the side close to the rear cover, and the plurality of guide posts are symmetrically distributed with the axis of the mounting plate as the center.

[0007] Preferably, the limiting groove is located above the mounting box, the plurality of positioning holes are symmetrically distributed with the axis of the heat sink as the center, and the wire hole is located on the side close to the front cover plate.

The lower part of the mounting plate 1 is provided with a front cover plate 8, a rear cover plate 9, and a side panel 10. The surface of the front cover plate 8 is provided with an air inlet groove 11 and a mounting hole 12. The surface of the rear cover plate 9 is provided with an exhaust groove 13. The two side panels 10 are located on both sides of the mounting plate 1. The surface of the side panels 10 is provided with a heat sink groove 14 and a mounting slot 15. The surface of the side panels 10 is provided with a mounting platform 16. The bottom of the mounting plate 1 is provided with a pin post 17 and a heat sink 18.

[0020] The heat sink 2 is located on the axis of the mounting plate 1, the mounting box 3 is located on the side close to the rear cover plate 9, and multiple guide posts 4 are symmetrically distributed with the axis of the mounting plate 1 as the center.

[0021] Furthermore, multiple guide posts 4 facilitate the mounting of the controller housing above the mounting plate 1, with the heat sink 2 and mounting box 3 directly contacting the heat-generating electronic components.

[0022] The limiting groove 6 is located above the mounting box 3, and multiple positioning holes 5 are symmetrically distributed with the axis of the heat sink 2 as the center. The wire hole 7 is located on the side close to the front cover plate 8.

[0023] Furthermore, both the limiting groove 6 and the positioning hole 5 maintain the installation position of the electronic components, facilitating their fixation.

[0024] The mounting holes 12 are located on the outside of the air intake slot 11. Multiple mounting holes 12 are arranged in a circular array with the axis of the air intake slot 11 as the center. The air intake slot 11 is located in the middle of the circular area in the center of the front cover plate 8.

[0025] Furthermore, the mounting hole 12 facilitates the fixing of the cooling fan on the surface of the front cover plate 8, and the circular air intake slot 11 is adapted to the working range of the cooling fan.

[0026] The heat dissipation slot 14 is located on the side close to the mounting box 3. The surfaces of the two side panels 10 are provided with mounting slots 15. The two mounting slots 15 are symmetrically distributed with the axis of the side panel 10 as the center. The exhaust slot 13 is located in the square area in the center of the rear cover plate 9.

[0027] Furthermore, the heat dissipation slot 14 exhausts the air duct blocked by the mounting box 3 from the side, preventing air from being blocked on one side.

[0028] The heat sink 18 is located below the heat sink 2. Multiple heat sinks 18 are arranged along the axial direction of the mounting plate 1. Multiple heat sinks 18 are located on the outside of the mounting box 3. Multiple ejector pins 17 are located on the surface of the heat sink 18. The heat sink 18 has a triangular cross-section.

[0029] Furthermore, multiple heat sinks 18 increase the heat dissipation area, and the triangular cross-section of the heat sinks 18 enhances the stability of the heat sinks 18, improves the heat distribution of the heat sinks 18, and increases the heat dissipation efficiency.

[0030] By setting up heat sink 2 and mounting box 3, the heat generated by electronic components is transferred to heat sink 18 through mounting plate 1. The heat sink 18 has a triangular cross-section, which increases the heat dissipation area and improves heat distribution.

[0031] Working principle:

[0032] Before use, place the electronic components on top of the mounting box 3 and the heat sink. The limiting groove 6 on the top of the mounting box 3 and the multiple positioning holes 5 on the surface of the heat sink limit the electronic components. The wire harness of the electronic components passes through the wire hole 7 on the surface of the mounting plate 1. The multiple guide posts 4 on the top of the mounting plate 1 facilitate the assembly of the upper housing. The multiple heat sinks 18 on the bottom of the mounting plate 1 dissipate the heat of the electronic components through the mounting plate 1. The heat sink 18 has a triangular cross-section to improve heat dissipation efficiency. The multiple heat sinks 18 are all arranged along the axial direction of the mounting plate 1 to facilitate air circulation and remove the heat from the surface of the heat sink 18. The surface of the front cover plate 8 has a circular air inlet groove 11, and the surface of the rear cover plate 9 has a square air inlet groove 11. The exhaust groove 13 has a wide range and an increased area. Multiple mounting holes 12 are opened on the outer side of the air inlet groove 11 to facilitate the installation of a cooling fan on the surface of the front cover plate 8 to enhance the heat dissipation effect. External air enters from the air inlet groove 11 of the front cover plate 8 and drives the heat on the surface of multiple heat sinks 18 to be discharged from the exhaust groove 13. A heat dissipation groove 14 is opened on the side panel 10 near the mounting box 3. The mounting box 3 blocks the air flow from the air inlet groove 11 to the exhaust groove 13. The heat dissipation groove 14 facilitates the discharge of the hot air blocked by the mounting box 3 from the side. The mounting platform 16 on the surface of the side panel 10 facilitates the connection with the base. Multiple ejector pins 17 on the surface of the heat sink 18 improve the structural strength of the heat sink 18 and facilitate the demolding of the heat sink 18 during casting.
