[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0018] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0021] In existing thermal management units, the condenser is installed on one side of the fan inlet. However, the fan noise is mainly discharged to the outside from the fan outlet along the air outlet duct, resulting in a relatively high noise level in the thermal management unit. In addition, the drive components, such as the compressor, water pump, water-side plate evaporator, water pipes, refrigerant pipes, PTC heater, and control box, are also installed inside the air outlet duct. This causes the airflow blown by the fan to hit the aforementioned drive components, further increasing the wind noise of the thermal management unit.

[0022] To solve the above problems, such as Figs. 1 to 3As shown, this utility model provides a thermal management unit, including a bracket 1, a fan 2, a condenser 3, an air outlet duct 4, a static pressure duct 5, and a drive component 6. The drive component 6 can drive the flow of coolant in the thermal management unit. The fan 2 is installed on the side inside the bracket 1. The fan 2 is connected to the air outlet duct 4 through the static pressure duct 5. The air outlet duct 4 is connected to the outside. The condenser 3 is installed between the air outlet duct 4 and the static pressure duct 5. The drive component 6 is installed on the bracket 1 and is installed on the outside of the air outlet duct 4 and the static pressure duct 5.

[0023] The condenser 3 is placed on one side of the air outlet of the fan 2, and the fan 2 is installed at the front end of the static pressure pipe 5. This allows the noise generated on the side of the air outlet of the fan 2 to be intercepted by the condenser 3 and the static pressure pipe 5, preventing all the noise from dissipating to the outside along the air outlet pipe 4. This reduces the noise generated by the fan 2 itself in the thermal management unit. Furthermore, the drive component 6 is placed outside the static pressure pipe 5 and the air outlet pipe 4, so that the air in the static pressure pipe 5 and the air outlet pipe 4 will not encounter the obstruction formed by the drive component 6. This prevents the air blown out by the fan 2 from hitting the drive component 6 and generating unnecessary noise, further reducing the noise generated by the thermal management unit.

[0024] The fan 2 includes a frame 21 and blades 22. The blades 22 are rotatably mounted on the frame 21, and the frame 21 is mounted on an opening in the static pressure duct. A gap is left between the blades 22 and the inner side of the frame 21. The smaller the gap, the lower the noise of the fan 2. In this invention, the gap between the blades 22 and the frame 21 on the fan 2 is very small. The smaller the gap, the smaller the airflow generated between the fan 2 and the frame 21, and the lower the noise emitted by the fan 2 itself, thereby reducing the noise of the thermal management unit.

[0025] A first flow equalization shroud 7 is provided on one side of the air inlet of the fan 2. The first flow equalization shroud 7 is attached to one side of the bracket 1. The first flow equalization shroud 7 is provided with first vent holes, which are distributed in a matrix. A second flow equalization shroud 8 is attached to the bracket 1. The second flow equalization shroud 8 is located at one end of the air outlet of the air outlet duct 4. The second flow equalization shroud 8 is provided with second vent holes, which are distributed in a matrix.

[0026] By installing a first flow equalization shroud 7 and a second flow equalization shroud 8 on the bracket 1 on the air inlet side of the fan 2 and the air outlet side of the air outlet duct 4 respectively, on the one hand, the fresh air entering the fan 2 and the static pressure chamber can be dispersed through the first vent hole, so that the air entering the fan 2 will not have turbulence and vortex, thereby reducing noise. At the same time, the second flow equalization shroud 8 can also prevent turbulence and vortex from the outside air discharged from the air outlet duct 4, thereby reducing the noise after the air is discharged from the air outlet duct 4.

[0027] The bracket 1 of this utility model is a rectangular cube. The fan 2 and the air outlet are installed on two adjacent sets of sides of the bracket 1. The air outlet duct 4 is arc-shaped. The static pressure duct 5 has four sets of openings from top to bottom on the side near the bracket 1. The fan 2 is installed in the openings. The side of the static pressure duct 5, the side of the air outlet duct 4 and the bracket 1 form a placement area 11. The drive component 6 is placed in the placement area 11.

[0028] Since the air outlet direction of the air outlet duct 4 is perpendicular to the air inlet direction, the air outlet duct 4 is curved, which can reduce the noise of the airflow flowing through the air outlet duct 4. Since the volume of the bracket 1 is larger than the volume of the air outlet duct 4, the drive component 6 can be placed in the above-mentioned placement area 11, so that the space utilization rate of the bracket 1 is maximized, and the airflow generated by the drive component 6 and the fan 2 is separated, so as to avoid the airflow generated by the fan 2 from hitting the drive component 6 and generating unnecessary noise.

[0029] It should be noted that if the air intake direction and the air exhaust direction are in the same direction, then a straight air exhaust duct 4 is used, which makes the exhaust smoother and can reduce the noise of the airflow in the air exhaust duct 4.

[0030] The inner wall of the static pressure pipe 5 is equipped with resistive sound insulation cotton and sound-absorbing wedges. Since the noise of the fan 2 mainly occurs at the air outlet of the fan 2, the noise level inside the static pressure pipe 5 is the highest. By installing the sound insulation device of sound insulation cotton and sound-absorbing wedges, the noise inside the static pressure pipe 5 can be reduced to the minimum, thereby minimizing the noise generated by the thermal management unit. The noise reduction method of resistive sound insulation cotton and sound-absorbing wedges is existing technology and will not be described in detail here.

[0031] The condenser 3 is made of metal and has channels formed on it. The channels are distributed in a matrix. The airflow generated by the fan 2 flows through the channels. The structure of the condenser 3 can also serve as a flow equalization plate, so that the airflow blown out by the fan 2 can avoid turbulence and vortex before entering the air outlet duct 4, thereby reducing the noise when the airflow passes through the condenser 3 and reducing the noise generated by the thermal management unit.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
