Description

Technical Field

[0001] This invention belongs to the field of heat transfer engineering technology for special vehicles, and specifically relates to an integrated fan volute. Background Technology

[0002] With the gradual application of hybrid powertrains in special vehicles and the increasing technical demands for flexible control of cooling fans in intelligent thermal management, the application of high-power cooling fans in special vehicles is becoming increasingly important. Since both the cooling fan and the engine exhaust (smoke) system are downstream of the vehicle's power unit cooling system, this further increases the space requirements for each component. Furthermore, high-power engines produce large exhaust volumes that are difficult to disperse into the air, significantly impacting the surrounding environment and the safety of personnel. Summary of the Invention

[0003] In view of this, the present invention provides an integrated fan housing that not only meets the space constraints of the power compartment of special vehicles, but also promotes the rapid diffusion of engine exhaust gas through the airflow generated by the cooling fan.

[0004] This invention is achieved through the following technical solution:

[0005] An integrated fan housing for cooling and exhaust gas dissipation of special vehicle engines includes: a fan housing body and two fans;

[0006] Peripheral equipment includes radiators and engine exhaust pipes;

[0007] The fan housing body has a frame structure, and two fans are arranged side by side inside the fan housing body; the heat sink is fixedly connected to the fan housing body and is opposite to the two fans, and the fans are used to dissipate the heat from the heat sink.

[0008] Two fan exhaust channels are arranged side by side between the two fans on the main body of the fan volute, and each fan exhaust channel is connected to the fan on the corresponding side;

[0009] An exhaust gas pipe channel is also provided between the two fans on the main body of the fan volute. The engine exhaust pipe is set along the exhaust gas pipe channel. The outlet of the exhaust gas pipe channel and the outlet of the fan exhaust channel are located on the same side of the main body of the fan volute.

[0010] The two fans rotate in opposite directions, so that the air generated by the two fans is discharged from the two fan exhaust channels in the same direction.

[0011] Furthermore, the outlet of the exhaust pipe channel and the outlet of the fan exhaust channel are located on the side of the fan volute body, which is called side A. The opening of each fan exhaust channel on side A is "L" shaped, and the horizontal parts of the "L" of the two fan exhaust channels are opposite each other, forming a U-shaped structure. The exhaust pipe channel is set within the space enclosed by the two "L" shaped fan exhaust channels.

[0012] Furthermore, the top surface of the fan housing body is provided with two fan mounting slots. The top of each fan mounting slot is a square opening for connecting with the heatsink. The bottom of each fan mounting slot is a cylindrical hole, and each fan is installed in the cylindrical hole. The top of the cylindrical hole is the fan air inlet.

[0013] Furthermore, peripheral equipment also includes fan motors;

[0014] The bottom of the cylindrical hole is provided with a fan motor mounting port, through which the fan motor is connected to the fan.

[0015] Furthermore, peripheral equipment also includes motor controllers;

[0016] A motor controller mounting port is provided in the middle of the bottom surface of the fan volute body, and the motor controller is connected to the fan volute body through the motor controller mounting port.

[0017] Beneficial effects:

[0018] (1) The integrated fan housing provided by the present invention, on the one hand, integrates the exhaust gas pipe channel on the fan housing, which can save space, improve space utilization, and meet the limited space requirements of the power compartment of special vehicles; on the other hand, in addition to removing the heat of the radiator and improving the heat dissipation efficiency, the air generated by the fan is discharged through the corresponding fan exhaust channel. The outlet of the exhaust gas pipe channel and the outlet of the fan exhaust channel are located on the same side of the main body of the fan housing. Therefore, the air discharged by the fan exhaust channel can quickly disperse the exhaust gas discharged by the exhaust gas pipe channel, effectively utilize the wind energy of the cooling fan, and reduce the impact of exhaust gas on the vehicle's surrounding environment and personnel.

[0019] (2) By setting the fan exhaust channel to an “L” shape and setting the exhaust pipe channel within the space enclosed by the two “L” shaped fan exhaust channels, the present invention can improve the space utilization of the fan volute body and further enable the exhaust gas discharged from the exhaust pipe channel to be quickly dispersed by the wind discharged by the fan.

[0020] (3) The bottom center of the fan volute body of the present invention is also provided with a motor controller mounting port, which further realizes the utilization of the space of the fan volute body and thus improves the space utilization rate. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] This embodiment provides an integrated fan housing for heat dissipation and exhaust gas discharge in special vehicle engines. See attached diagram. Figure 1 It includes the fan volute body 1 and two fans 6;

[0027] Peripheral equipment includes radiators, fan motors, motor controllers, and engine exhaust pipes;

[0028] The fan housing body 1 is a frame structure, and two fans are arranged side by side inside the fan housing body 1; the heat sink is fixedly connected to the fan housing body 1 and is opposite to the two fans. The fans are used to remove the heat from the heat sink and improve the heat dissipation efficiency.

[0029] Two fan exhaust channels 2 are arranged side by side between the two fans 6 on the fan volute body 1, and each fan exhaust channel 2 is connected to the fan 6 on the corresponding side.

[0030] A waste gas exhaust pipe channel 5 is also provided between the two fans 6 on the fan volute body 1. The engine exhaust pipe is set along the waste gas exhaust pipe channel 5. The outlet of the waste gas exhaust pipe channel 5 and the outlet of the fan exhaust channel 2 are located on the same side of the fan volute body 1.

[0031] The two fans 6 rotate in opposite directions, so that the air generated by the two fans 6 is discharged from the two fan outlet channels 2 in the same direction.

[0032] In this embodiment, on the one hand, integrating the exhaust pipe channel 5 into the fan volute saves space, improves space utilization, and meets the space constraints of the compact power compartment of special vehicles; on the other hand, in addition to removing heat from the radiator and improving heat dissipation efficiency, the fan 6 generates air that is discharged through the corresponding fan exhaust channel 2. The outlet of the exhaust pipe channel 5 and the outlet of the fan exhaust channel 2 are located on the same side of the fan volute body 1, so the air discharged through the fan exhaust channel 2 can quickly disperse the exhaust gas discharged through the exhaust pipe channel 5, reducing the impact of exhaust gas on the vehicle's surrounding environment and personnel.

[0033] Let the mounting surface of the heat sink on the fan volute body 1 be the top surface, and the surface opposite the top surface be the bottom surface;

[0034] The top surface of the fan housing body 1 is provided with two fan mounting slots. The top of each fan mounting slot is a square opening for connecting with the heatsink. The bottom of each fan mounting slot is a cylindrical hole, and each fan 6 is installed in the cylindrical hole. The top of the cylindrical hole (the top is the intersection of the cylindrical hole and the square opening) is the fan air inlet 7, and the bottom of the cylindrical hole is provided with a fan motor mounting port 3. The fan motor is connected to the fan 6 through the fan motor mounting port 3. The square opening and the cylindrical hole are smoothly connected.

[0035] In one specific embodiment, the outlet of the exhaust pipe channel 5 and the outlet of the fan exhaust channel 2 are located on the side of the fan volute body 1, which is designated as side A. Two or more fan exhaust channels can be provided on side A to improve heat dissipation efficiency. In this specific embodiment, four fan exhaust channels are provided.

[0036] In one specific embodiment, the opening of each fan exhaust channel 2 on the side A is "L" shaped, and the horizontal portions of the "L" of the two fan exhaust channels 2 are opposite to each other, forming a U-shaped structure;

[0037] The exhaust gas pipe channel 5 is set within the space enclosed by the two "L"-shaped fan exhaust channels 2;

[0038] By setting the fan exhaust duct 2 to an "L" shape and placing the exhaust pipe 5 within the space enclosed by the two "L" shaped fan exhaust ducts 2, the space utilization rate of the fan volute body 1 can be improved on the one hand, and the exhaust gas discharged from the exhaust pipe 5 can be quickly dispersed by the wind discharged from the fan 6 on the other hand.

[0039] The bottom center of the fan volute body 1 is also provided with a motor controller mounting port 4 for connecting to the motor controller, thereby further realizing the utilization of the space of the fan volute body 1. Without affecting the original airflow field, the fan, drive motor, motor controller and exhaust pipe are highly integrated, thereby improving the space utilization rate.

[0040] Working principle:

[0041] The motor controller controls the start and stop of the corresponding fan by controlling the corresponding fan motor. When the fan rotates, air enters the fan from the fan inlet 7 and is then discharged from the fan outlet 2, carrying away the heat from the radiator. At the same time, the engine exhaust pipe is set along the exhaust pipe channel 5. The outlet of the exhaust pipe channel 5 and the outlet of the fan outlet channel 2 are located on the same side of the fan volute body 1. The air discharged from the fan outlet channel 2 quickly disperses the exhaust gas discharged from the engine exhaust pipe.

[0042] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
