Description

Technical Field

[0001] The invention belongs to the field of automobile auxiliary instrument panel manufacturing, and in particular relates to a high-pressure and air volume system of a series reverse-rotating fan. Background Art

[0002] The car's console, also called the center channel, is generally abbreviated as CNSL. It is a very important component in interior design. Due to the limited space inside the car, the CNSL is usually made as small as possible to expand the space inside the car. Driven by electric vehicles, the space inside the car has been fully exploited, and the CNSL is often equipped with some usage scenarios to enrich the functions inside the car, such as storage needs. Therefore, the design requirements for the CNSL structure are further improved. However, due to the compact structure of the CNSL inside the car and the limited internal space, the heat dissipation duct is often complex in structure and has a high flow resistance. If the heat is not discharged smoothly and accumulates in the CNSL, it will lead to reduced product performance and even affect other CNSL products. Summary of the invention

[0003] The purpose of the present invention is to provide a high-pressure and air volume system with a series reverse fan, which solves the problem that the CNSL waste heat energy inside the car is difficult to discharge and avoids affecting the product performance.

[0004] To achieve the above-mentioned object of the invention, the technical solution of the present invention is as follows:

[0005] A series reverse fan high air pressure and air volume system is arranged in the heat dissipation air duct of the auxiliary instrument panel of an automobile, including a wind cover and a radiator, and also includes a series double axial flow fan assembly with two fans with opposite directions arranged in series. The series double axial flow fan assembly is connected to the radiator. The series double axial flow fan assembly draws air from one end away from the radiator, blows it toward the radiator, and then flows out from the other end away from the radiator. The wind direction inside the series double axial flow fan assembly always remains consistent.

[0006] The present invention designs a series reverse fan high air pressure and air volume system to form a strong airflow in a limited space by arranging two series double axial flow fan assemblies with fans rotating in opposite directions in series on the premise of compact CNSL structure. This design can not only achieve efficient air circulation in a limited space, but also significantly improve the uniformity of air flow and increase the air volume and pressure, thereby ensuring the efficiency and comfort of the system.

[0007] In the above-mentioned series reverse fan high air pressure and air volume system, the two fans with opposite directions are respectively a first fan and a second fan, the first fan and the second fan are connected to each other, and the number of blades of the first fan and the number of blades of the second fan are the same.

[0008] The main function of the present invention is to form a staggered airflow in a limited space, realize efficient air circulation, improve the uniformity of air flow, and increase the air volume and pressure. At the same time, the number of the first fan blades and the second fan blades is the same to ensure the stability of the air volume and wind direction, so as to further improve the air volume intensity inside the CNSL.

[0009] In the above-mentioned series reverse fan high air pressure and air volume system, the first fan is arranged close to the end surface of the radiator and the first fan blades rotate clockwise, and the second fan is arranged away from the radiator and the second fan blades rotate counterclockwise.

[0010] The first fan blade rotates clockwise, and the wind direction moves from away from the radiator to close to the radiator. The second fan blade rotates counterclockwise, and the wind direction moves from away from the radiator to close to the radiator. Fans rotating in opposite directions produce staggered airflows, which can reduce eddy currents and turbulence and improve air flow and uniformity. The first fan and the second fan of the present invention mutually enhance the kinetic energy of the airflow, and the coverage area is wider.

[0011] In the above-mentioned series reverse fan high air pressure and air volume system, the first fan blades and the second fan blades correspond one to one and are mirror images of each other.

[0012] The present invention ensures that the air inlet direction and the air outlet direction inside the series dual axial flow fan assembly are consistent by having the first fan blade and the second fan blade correspond to each other one by one and are mirror images of each other, so as to increase the airflow intensity in a limited space.

[0013] In the above-mentioned series reverse fan high air pressure and air volume system, the series dual axial flow fan assembly also includes a first fan fixed drive component respectively matched with the first fan and a second fan fixed drive component respectively matched with the second fan.

[0014] In order to facilitate installation and maintenance and to be applicable to as many environments and purposes as possible, the present invention separates the fixing and driving of the first fan from the fixing and driving of the second fan, so that the two fans can be inspected or replaced separately. In special scenarios, only one fan can be kept running.

[0015] Preferably, in order to further guide the airflow in the series reverse fan high air pressure and air volume system, the first fan fixed drive member and the second fan fixed drive member are both provided with guide surfaces, that is, the airflow in the CNSL is sucked into the system as much as possible to accelerate the heat circulation inside the CNSL.

[0016] In the above-mentioned series reverse fan high wind pressure and air volume system, the radiator also includes a semiconductor heat exchange unit, which is arranged on the lower bottom surface of the radiator, and the wind cover includes a cover net, which is arranged on the outside of the series double axial flow fan assembly.

[0017] The present invention integrates the space inside the CNSL and the working principle of the heat exchanger, and arranges a series dual axial fan assembly on one side of the radiator to efficiently let the outside air flow in and thus discharge the hot air. However, in order not to affect the operation of the semiconductor heat exchange unit, the semiconductor heat exchange unit is arranged on the bottom surface of the radiator to prevent the airflow of the series dual axial fan assembly from directly affecting the operation of the radiator.

[0018] In the above-mentioned series reverse fan high air pressure and air volume system, a flow gap is arranged between the air cover and the top of the radiator, and the air cover is arranged to open toward the lower bottom surface.

[0019] By setting a flow gap between the wind hood and the top of the radiator, efficient circulation of air in the system is further ensured; and the wind hood opened toward the lower bottom surface is provided to give the semiconductor heat exchange unit as much working space as possible and also reduce possible heat accumulation.

[0020] Furthermore, a heat dissipation gap is provided between the series-connected dual axial-flow fan assembly and the bottom surface of the radiator.

[0021] Furthermore, the wind shield is arranged parallel to two side surfaces of the radiator and gradually away from the radiator from top to bottom.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] (1) The present invention designs a series reverse fan high air pressure and air volume system. Under the premise of a compact CNSL structure, a series double axial flow fan assembly with two fans in opposite directions is arranged in series to form a strong airflow in a limited space. This design can not only achieve efficient air circulation in a limited space, but also significantly improve the uniformity of air flow and increase the air volume and pressure, thereby ensuring the efficiency and comfort of the system.

[0024] (2) The main function of the present invention to connect two fans in series with opposite rotation directions is to form staggered airflow in a limited space, realize efficient air circulation, improve the uniformity of air flow, and increase the air volume and pressure. At the same time, the number of the first fan blades and the second fan blades is the same to ensure the stability of the air volume and wind direction, so as to further improve the air volume intensity inside the CNSL; the first fan blades and the second fan blades correspond to each other one by one and are mirror images of each other to ensure that the air intake direction and the air outlet direction inside the series dual axial flow fan assembly are consistent, so as to increase the airflow intensity in the limited space.

[0025] (3) In order to facilitate installation and maintenance and to be applicable to as many environments and uses as possible, the present invention separates the fixing and driving of the first fan and the second fan, so that the two fans can be inspected or replaced separately. In special scenarios, only one fan can be kept running. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Specific implementation modes are listed below to further explain the technical solution of the present invention in detail.

[0034] like Figure 1 As shown, this embodiment provides a series reverse fan high air pressure and air volume system, which is arranged in the heat dissipation air duct of the auxiliary instrument panel of the automobile, and includes a wind cover 1, a radiator 2, and a series double axial flow fan assembly 3 in which two fans with opposite directions are arranged in series. Among them, the wind cover 1 includes a cover net 11, and the cover net 11 is arranged outside the series double axial flow fan assembly 3; the wind cover 1 is arranged toward the lower bottom surface opening, and the wind cover 1 is arranged parallel to the two side surfaces of the radiator 2 and gradually away from the radiator 2 from top to bottom.

[0035] like Figure 2 As shown, the radiator 2 also includes a semiconductor heat exchange unit 21, which is arranged on the lower bottom surface of the radiator 2. In this embodiment, the semiconductor heat exchange unit 21 is provided with sufficient working space by providing a downwardly opening wind hood and the semiconductor heat exchange unit 21 arranged on the lower bottom surface of the radiator 2, and the semiconductor heat exchange unit 21 located on the lower bottom surface and the series dual axial flow fan assembly 3 are neither connected nor arranged facing each other, so they will not affect each other's working efficiency during operation. In addition, the end of the wind hood 1 close to the semiconductor heat exchange unit 21 is not covered by the hood net 11 and is provided with a hood net gap 12, so as to further provide the semiconductor heat exchange unit 21 with sufficient working space.

[0036] Combination Figure 3As shown, the radiator 2 includes a plurality of fins 22, which are coaxially arranged with the series dual axial fan assembly 3, so that the series dual axial fan assembly 3 can take away the waste heat between the plurality of fins 22 as much as possible. The series dual axial fan assembly 3 is connected to the radiator 2, and the series dual axial fan assembly 3 sucks air from one end away from the radiator 2, blows it toward the radiator 2, and then flows out from the end away from the radiator 2, and the wind direction inside the series dual axial fan assembly 3 is always kept consistent.

[0037] A circulation gap (not shown in the figure) is provided between the wind cover 1 and the top of the radiator 2 to ensure air circulation of the radiator 2. A heat dissipation gap 34 is provided between the series dual axial flow fan assembly 3 and the bottom surface of the radiator 2. The heat dissipation gap 34 cooperates with the cover net gap 12 and the opening surface of the wind cover 1 to ensure that the radiator 2 exchanges heat with as much high-temperature airflow as possible. The radiator 2 is in direct contact with the wind cover 1 to guide the flow direction of the airflow. The series dual axial flow fan assembly 3 is connected to the radiator 2 to dissipate heat for the semiconductor heat exchange unit 21.

[0038] like Figure 4 and Figure 5 As shown, the series dual axial flow fan assembly 3 includes two fans with opposite directions: a first fan 31 and a second fan 32, the first fan 31 and the second fan 32 are connected and arranged, and the number of the first fan blades 311 and the second fan blades 321 are the same, and also includes a first fan fixed driving member 312 respectively matched with the first fan 31 and a second fan fixed driving member 322 matched with the second fan 32. The first fan fixed driving member 312 and the second fan fixed driving member 322 are both provided with a guide surface 33.

[0039] In order to facilitate installation and maintenance and to be applicable to a variety of environments and purposes as much as possible, the fixing and driving of the first fan 31 and the fixing and driving of the second fan 32 in this embodiment are separately set, that is, the system sets the first fan 31 and the second fan 32 in a dual-axis manner on the basis of series connection. Therefore, the rotational wind direction of the two fans can be adjusted according to the actual scenario, and the two fans can be separately repaired or replaced. In special scenarios, only one fan can be kept in operation. The first fan fixed drive member 312 and the second fan fixed drive member 322 are both provided with guide surfaces 33 to further guide the airflow in the series reverse fan high air pressure and air volume system, that is, to suck the airflow in the CNSL into the system as much as possible to accelerate the heat circulation inside the CNSL.

[0040] The first fan 31 is arranged close to the end surface of the radiator 2 and the first fan blade 311 rotates clockwise instantaneously, and the second fan 32 is arranged away from the radiator 2 and the second fan blade 321 rotates counterclockwise. The first fan blade 311 rotates clockwise instantaneously, and the wind direction moves from away from the radiator 2 to close to the radiator 2, and the second fan blade 232 rotates counterclockwise, and the wind direction moves from away from the radiator 2 to close to the radiator 2. Fans rotating in opposite directions produce staggered airflows, which can reduce eddy and turbulent phenomena and improve air fluidity and uniformity. The first fan 31 and the second fan 32 of the present invention mutually enhance the kinetic energy of the airflow and cover a wider range.

[0041] In order to further improve the airflow stability and air volume intensity of the high air pressure and air volume system of the series reverse fan, the present embodiment has the same number of the first fan blades 311 and the second fan blades 321, and the first fan blades 311 and the second fan blades 321 correspond to each other one by one and are mirror images of each other. For the two fans that are reversed in series, no matter whether the first fan blades 311 rotate clockwise or counterclockwise when the first fan 31 is working, the second fan blades 321 of the second fan 32 are always the mirror image structure of the first fan blades 311, keeping the first fan 31 and the second fan 32 rotating in opposite directions, but the air inlet direction is consistent with the air outlet direction.

[0042] The working principle of the present invention is as follows: the series reverse fan high air pressure and air volume system is arranged in the heat dissipation duct of the CNSL, the radiator 2 and the semiconductor heat exchange unit 21 arranged on the lower bottom surface of the radiator 2 exchange the waste heat in the CNSL, and at the same time, the series double axial fan assembly 3 coaxially arranged with the multiple heat sinks 22 dissipates heat for the semiconductor heat exchange unit 21 and circulates air in the heat dissipation duct, the second fan blades 321 rotate counterclockwise to suck the external cold air flow into the heat dissipation duct and send air to the first fan 31, and the first fan blades 311 rotate clockwise to blow the cold air flow into the multiple heat sinks 22 of the radiator 2. Since the air outlet directions of the first fan 31 and the second fan 32 are the same, the waste heat air flow flows out from the other side of the series double axial fan assembly 3 to the outside of the heat dissipation duct.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
