Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to an aluminum die-casting controller box for a new energy vehicle. Background Art

[0002] With the increasing urgency of energy and environmental issues, the rapid development of new energy vehicles is the trend of the times. The motor controller is a key component in new energy vehicles, and the IGBT module is the core device of the motor controller. The radiator is an important part of the control system of new energy vehicles, and is responsible for cooling and dissipating the IGBT module (insulated gate bipolar transistor). Generally, the current flowing through the IGBT is large, and the switching frequency is high, resulting in large losses in the IGBT device. If the heat cannot be dissipated in time, it is easy to cause the IGBT module to heat up and be damaged, causing the vehicle to fail to control during driving. Therefore, it is particularly important to use a reasonable heat dissipation system to operate within a reliable temperature range.

[0003] Most existing new energy vehicle controller boxes are equipped with cooling water channel structures to dissipate heat, but most of the new energy vehicle controller boxes are closed, which easily generates a lot of heat during operation, and most of the heat does not have good heat dissipation holes to evacuate. Utility Model Content

[0007] In addition, a preferred structure is that the dust and water blocking mechanism includes a fixing ring, a dust plate is connected to the top of the fixing ring, and an extended convex ring is installed on the outside of the bottom of the fixing ring.

[0008] In addition, a preferred structure is that a plurality of connecting rods are installed at equal distances on the top of the extending protruding ring, and a waterproof cover is connected to the top of the extending protruding ring through the connecting rods, and the diameter of the waterproof cover is larger than the diameter of the extending protruding ring.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4The aluminum die-cast controller box of a new energy vehicle includes a controller box 1. A box cover 11 is arranged on the top of the controller box 1. A plurality of heat dissipation holes 111 are opened at equal distances on the top of the box cover 11. A fixing ring 2 is fixedly installed on the outside of the heat dissipation hole 111 on the top of the box cover 11, and a dust and water-proof mechanism 3 is arranged on the outside of the fixing ring 2 on the top of the box cover 11. The dust and water-proof mechanism 3 and the box cover 11 are connected and fixed by a plurality of fixing bolts 4. It is worth noting that the specific structure, connection method and working method of the controller box 1 and the box cover 11 are all prior arts, which do not belong to the main technical problems solved in the present technical scheme. Therefore, they are not elaborated in the present technical scheme. At the same time, the diameter of the heat dissipation hole 111 gradually increases from the bottom to the top.

[0021] Meanwhile, the dust and water blocking mechanism 3 comprises a fixing ring 312 , the top of which is connected with a dust plate 31 , and an extending convex ring 311 is installed outside the bottom of the fixing ring 312 .

[0022] In addition, a plurality of connecting rods 32 are installed at equal distances on the top of the extending protruding ring 311 , and a waterproof cover 33 is connected to the top of the extending protruding ring 311 through the connecting rods 32 . The diameter of the waterproof cover 33 is larger than the diameter of the extending protruding ring 311 .

[0023] Furthermore, a plurality of mounting holes 3111 are formed at equal intervals on the top of the extending protruding ring 311 and between adjacent connecting rods 32 .

[0024] Furthermore, the top of the waterproof cover 33 is inclined from the center to the outside, and a limiting groove is provided at the bottom of the waterproof cover 33, and the limiting groove is inclined from the center to both sides.

[0025] Furthermore, a water retaining ring 331 is provided at the bottom of the waterproof cover 33 and outside the extended protruding ring 311 .

[0026] In this embodiment, the heat dissipation holes 111 can increase the air flow between the inside and outside of the controller case 1, and the heat generated by the controller case 1 during operation can be evacuated to a certain extent, thereby reducing the temperature inside the controller case 1. At the same time, since the diameter of the heat dissipation holes 111 gradually increases from the bottom to the top, it is beneficial for the heat in the controller case 1 to be discharged out of the controller case 1 faster, and the flow resistance of the air when passing through is reduced, so that the cavity can flow out more smoothly, thereby enhancing its heat dissipation efficiency.

[0027] At the same time, the dustproof plate 31 of the dustproof and water-blocking mechanism 3 can prevent dust and fine particles in the air from entering the controller case 1 along the heat dissipation through-hole 111, and the waterproof cover 33 and the fixed ring 2 of the dustproof and water-blocking mechanism 3 can prevent liquid and moisture on the top from entering the controller case 1 along the heat dissipation through-hole 111, and the bottom of the waterproof cover 33 is located on the outside of the extended convex ring 311 and a water retaining ring 331 is provided. When water drips downward along the inclined surface of the waterproof cover 33, the water retaining ring 331 prevents the water from overflowing along the bottom of the waterproof cover 33.

[0028] In the utility model, the heat dissipation holes 111 can increase the air flow between the inside and outside of the controller case 1, and the heat generated when the controller case 1 is in operation can be evacuated to a certain extent, thereby reducing the temperature inside the controller case 1. At the same time, the dust and fine particles in the air can be prevented from entering the controller case 1 through the heat dissipation holes 111 through the dust and water blocking mechanism 3 and the fixing ring 2, and the liquid and moisture on the top can be prevented from entering the controller case 1 through the heat dissipation holes 111.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
