Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a cooling system and a vehicle. Background Technology

[0002] The engine control unit (ECU) primarily functions in data storage, data conversion, actuator control, waveform conversion, and calculation. As the control and communication center for various electronic control systems in a vehicle, its stability directly impacts the vehicle's driving stability, fuel economy, safety, and comfort. With the increasing maturity of advanced electronic technology and its widespread application in automobiles, automotive engine ECUs are becoming increasingly complex. If an ECU fails, the vehicle will be unable to start, unable to drive normally, and may even experience risks such as loss of control or fire. Therefore, the safety requirements for engine ECUs are very high.

[0003] When the ECU is located in the harsh conditions of the engine compartment, heat insulation and cooling are the primary issues to be addressed to ensure the normal operation of the ECU, given the high temperature inside the engine compartment. Utility Model Content

[0004] In view of this, the present invention provides a cooling system and vehicle to solve the problem of how to insulate and cool the engine control unit located in the engine compartment.

[0005] In a first aspect, this utility model provides a cooling system for cooling a control module; the cooling system includes:

[0006] The protective box has a protective chamber and a cooling chamber inside; the control module is located in the protective chamber; the protective box includes a first plate, which is located between the protective chamber and the cooling chamber; the protective box also includes an air inlet and an air outlet, which are respectively connected to the cooling chamber.

[0007] The cooling pipe has one end connected to the air outlet and the other end adapted to connect to the engine's air intake pipe.

[0008] Beneficial effects: The cooling system provided by this embodiment of the invention, by setting up a protective box, forms a protective chamber and a cooling chamber within the protective box; the control module is placed in the protective chamber, and the cooling pipe is connected to the engine's intake pipe, thereby satisfying the cooling of the control module while also providing safety protection for the control module, preventing mud, dust, or water from entering the control module. This ensures that the control module is in a good working environment, making its operation more stable and reliable.

[0009] In one alternative implementation, the first plate has a partially through-hole formed with an opening, and the control module is disposed in at least a portion of the opening.

[0010] Beneficial effects: Since the first plate is located between the protection chamber and the cooling chamber, and an opening is formed through a portion of the first plate, and at least a portion of the control module is located in the opening, the airflow flowing through the cooling chamber can come into contact with the control module, allowing the control module to be directly cooled, thus improving the heat dissipation effect of the control module.

[0011] In one alternative embodiment, the protective box further includes a sealing gasket, which is disposed around the opening and abuts against the control module and the first plate.

[0012] Beneficial effects: By surrounding the opening with a sealing gasket and abutting between the control module and the first plate, the opening can be completely closed after the control module and the first plate are tightly installed, and the gaps are also sealed, thereby blocking the connection between the protection chamber and the cooling chamber at the opening and preventing impurities, dust and other contaminants from entering the protection chamber.

[0013] In one alternative implementation, the protective box includes:

[0014] The air intake cooling cover and the protective cover are interlocked and merged to form a protective chamber.

[0015] The first plate is formed on the air intake cooling cover plate, which also includes a second plate. The second plate is disposed on the side of the first plate away from the protective chamber, and the second plate and the first plate together enclose the cooling chamber.

[0016] In one alternative embodiment, the air inlet is located above the protective box, which is suitable for guiding airflow into the cooling chamber in a vertical direction.

[0017] Beneficial effects: By placing the air intake above the protective box, the airflow enters the cooling chamber in a vertical direction. This allows the air intake to be further from the ground after the cooling system of this embodiment is installed in the engine compartment, resulting in better air quality and reducing the entry of mud, dust, or water.

[0018] In one optional embodiment, the first plate and / or the second plate are provided with at least one first drain hole, which is connected to the cooling chamber.

[0019] The first plate and / or the second plate are also provided with at least one second drain hole, which is connected to the cooling chamber.

[0020] The second drain hole is located below the first drain hole along the height direction.

[0021] In one alternative embodiment, the first plate and / or the second plate are further provided with a sedimentation tank, which is disposed in the height direction opposite to the first drain hole and opposite to the second drain hole, and the sedimentation tank is adapted to be inclined toward the second drain hole.

[0022] Beneficial effects: To prevent dust or mud accumulation inside the protective box, this embodiment incorporates a drainage structure within the box. Along the gas flow path, the first drainage hole is positioned upstream of the second drainage hole. This allows for priority drainage from the first drainage hole, while the second drainage hole, positioned vertically below the first, can further drain dirt if the first hole cannot completely remove it, ensuring a clean environment inside the protective box.

[0023] In one optional embodiment, the cooling system further includes: an air filter housing adapted to install an air filter element; the air filter housing has a control module cooling air inlet, the other end of a cooling pipe is connected to the control module cooling air inlet, and the control module cooling air inlet is located upstream of the air filter element along the airflow direction.

[0024] Beneficial effects: By adding an additional cooling pipe to the front end of the air filter housing, the control module is placed in a protective box with a cooling chamber connected to the cooling pipe. This allows the airflow entering the engine intake pipe to cool the control module. Furthermore, the other end of the cooling pipe is connected to the control module's cooling air inlet, which is positioned upstream of the air filter along the airflow direction. This prevents mud, dust, and other contaminants flowing through the cooling pipe from polluting the engine intake pipe, ensuring the engine draws in clean air.

[0025] In one alternative embodiment, the protection box further includes a wiring harness conduit connected to the protection chamber, the wiring harness conduit being adapted to lead out the connection harness of the control module.

[0026] Secondly, this utility model also provides a vehicle, comprising:

[0027] The vehicle body, which includes an engine compartment;

[0028] The control module is located in the engine compartment;

[0029] And as mentioned above, the cooling system has a control module located within it.

[0030] Since the vehicle includes a cooling system, it has the same effect as a cooling system, so it will not be elaborated on here. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0049] The engine control unit (ECU) primarily functions in data storage, data conversion, actuator control, waveform conversion, and calculation. As the control and communication center for various electronic control systems in a vehicle, its stability directly impacts the vehicle's driving stability, fuel economy, safety, and comfort. With the increasing maturity of advanced electronic technology and its widespread application in automobiles, automotive engine ECUs are becoming increasingly complex. If an ECU fails, the vehicle will be unable to start, unable to drive normally, and may even experience risks such as loss of control or fire. Therefore, the safety requirements for engine ECUs are very high.

[0050] As an electronic component, the ECU needs to be adaptable to any installation location within a vehicle and possess strong resistance to harsh environments such as heat radiation, humidity, and vibration. Furthermore, since cars operate in various environments worldwide, the ECU requires a wider temperature range to operate within. When the ECU is located in the harsh conditions of the engine compartment, heat insulation and cooling are paramount to ensuring its proper functioning due to the high temperatures within the compartment. Related technologies involve placing the ECU within the engine's intake manifold, thus cooling it simultaneously with the intake air. However, in harsh environments, the air entering the engine's intake manifold may contain mud, dust, or water, which can easily damage the ECU.

[0051] The cooling system provided in the embodiment of this utility model includes a protective box 1, which contains a protective chamber 119 and a cooling chamber 118. The control module 2 is placed in the protective chamber 119, and the cooling pipe 3 is connected to the engine's intake pipe. This system not only cools the control module 2 but also provides safety protection for it, preventing mud, dust, or water from entering the control module 2.

[0052] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0053] According to an embodiment of the present invention, a cooling system is provided for cooling the control module 2; the cooling system includes:

[0054] The protective box 1 has a protective chamber 119 and a cooling chamber 118 inside it; the control module 2 is disposed in the protective chamber 119; the protective box 1 includes a first plate 1101, which is disposed between the protective chamber 119 and the cooling chamber 118; the protective box 1 also includes an air inlet 111 and an air outlet 112, which are respectively connected to the cooling chamber 118.

[0055] The cooling pipe 3 is connected at one end to the air outlet 112 and at the other end to the engine's air intake pipe.

[0056] The protective box 1 in this embodiment is internally divided into two chambers: a protective chamber 119 and a cooling chamber 118, and the two chambers are close to each other. The two chambers can be separated by a plate; for example, in this embodiment, a first plate 1101 is disposed between the protective chamber 119 and the cooling chamber 118. Alternatively, the two chambers can be at least partially connected; for example, an opening 117 can be provided on the first plate 1101 to ensure the heat dissipation effect of the control module 2. The form of the opening 117 will be described in detail below.

[0057] Since the protective chamber 119 and the cooling chamber 118 are close to each other, when the airflow passes through the cooling chamber 118, it can simultaneously carry away the heat of the protective chamber 119, thereby achieving the effect of cooling and heat dissipation.

[0058] The air inlet 111 and the air outlet 112 are respectively connected to the cooling chamber 118. The cooling pipe 3 is connected at one end to the air outlet 112 and at the other end to the engine's intake pipe. Thus, under the guidance of the engine's intake fan, the airflow can enter through the air inlet 111, and after passing through the cooling chamber 118, it can be discharged through the air outlet 112.

[0059] In some embodiments, combined with Figure 1 As shown, the cooling system also includes: an air filter housing 4, which is suitable for installing an air filter element; the air filter housing 4 has a control module cooling air inlet 41, the other end of the cooling pipe 3 is connected to the control module cooling air inlet 41, and the control module cooling air inlet 41 is located upstream of the air filter element along the airflow direction.

[0060] In this embodiment, an additional cooling pipe 3 is added to the front end of the air filter housing 4, and the control module 2 is placed in the protective box 1 with a cooling chamber 118. The cooling chamber 118 is connected to the cooling pipe 3, thereby utilizing the air entering the engine intake pipe to cool the control module 2.

[0061] Furthermore, the other end of the cooling pipe 3 is connected to the cooling air inlet 41 of the control module, and the cooling air inlet 41 of the control module is located upstream of the air filter along the airflow direction, thereby preventing mud, sand, dust and other contaminants flowing through the cooling pipe 3 from polluting the engine intake pipe and ensuring that the engine can draw in clean air.

[0062] Combination Figure 1 As shown, the air filter housing 4 may also include an air filter dirty pipe 42, and the control module cooling air inlet 41 and the air filter dirty pipe 42 are arranged side by side at the upstream position of the air filter element.

[0063] The cooling system provided in this embodiment of the invention includes a protective box 1, which contains a protective chamber 119 and a cooling chamber 118. The control module 2 is housed within the protective chamber 119, and the cooling pipe 3 is connected to the engine's intake pipe. This system not only cools the control module 2 but also provides safety protection, preventing environmental contaminants such as mud, dust, or water from entering the control module 2. This ensures the control module 2 operates in a suitable environment, making its operation more stable and reliable.

[0064] In this embodiment, the control module 2 may include an engine control unit (ECU), an air conditioning system control module, a body control system control module, a braking system control module, a transmission control module, etc.

[0065] In some embodiments, combined with Figure 2 As shown, the first plate 1101 has a partially through-hole forming an opening 117, and the control module 2 is disposed in at least a portion of the opening 117.

[0066] Since the first plate 1101 is disposed between the protection chamber 119 and the cooling chamber 118, and an opening 117 is formed through the first plate 1101, and at least a portion of the control module 2 is disposed in the opening 117, the airflow flowing through the cooling chamber 118 can come into contact with the control module 2, so that the control module 2 can be directly cooled, thereby improving the cooling effect of the control module 2.

[0067] In some embodiments, combined with Figure 3 , Figure 4 As shown, the protective box 1 also includes a sealing gasket 21, which is disposed around the opening 117 and abuts against the control module 2 and the first plate 1101.

[0068] By surrounding the opening 117 with a sealing gasket 21 and abutting between the control module 2 and the first plate 1101, the opening 117 can be completely closed after the control module 2 and the first plate 1101 are tightly installed. The gaps are also sealed, thereby blocking the communication between the protection chamber 119 and the cooling chamber 118 at the opening 117 and preventing impurities, dust and other contaminants from entering the protection chamber 119.

[0069] The sealing gasket 21 can be made of a soft material, such as rubber or foam.

[0070] In some embodiments, combined with Figure 4 As shown, the protective box 1 includes:

[0071] The air intake cooling cover 11 and the protective cover 12 are interlocked and merged to form a protective chamber 119.

[0072] The first plate 1101 is formed on the air intake cooling cover 11. The air intake cooling cover 11 also includes a second plate 1102. The second plate 1102 is disposed on the side of the first plate 1101 away from the protective chamber 119, and the second plate 1102 and the first plate 1101 together enclose the cooling chamber 118.

[0073] In this embodiment, the second plate 1102 and the first plate 1101 can be integrally formed to jointly constitute the air intake cooling cover 11.

[0074] In some embodiments, combined with Figure 1 As shown, the air inlet 111 is located above the protective box 1, which is suitable for guiding the airflow into the cooling chamber 118 in the vertical direction.

[0075] By positioning the air intake 111 above the protective box 1, airflow enters the cooling chamber 118 in a vertical direction. This allows the air intake 111 to be further from the ground after the cooling system of this embodiment is installed in the engine compartment, resulting in better air quality entering the air intake 111 and reducing the entry of mud, dust, or water.

[0076] In some embodiments, combined with Figure 6 , Figure 7 As shown, the first plate 1101 and / or the second plate 1102 are provided with at least one first drain hole 113, and the first drain hole 113 is connected to the cooling chamber 118.

[0077] The first plate 1101 and / or the second plate 1102 are also provided with at least one second drain hole 116, which is connected to the cooling chamber 118.

[0078] The second drain hole 116 is located below the first drain hole 113 along the height direction.

[0079] In some embodiments, the first plate 1101 and / or the second plate 1102 are further provided with a sedimentation tank 115. The sedimentation tank 115 is disposed in the height direction below the first drain hole 113 and above the second drain hole 116. The sedimentation tank 115 is adapted to be disposed at an angle toward the second drain hole 116.

[0080] To prevent dust or mud from accumulating inside the protective box, this embodiment includes a drainage structure inside the protective box 1. Specifically, the first drainage hole 113 and the second drainage hole 116 are both connected to the cooling chamber 118.

[0081] Along the gas flow path, the first drain hole 113 is positioned relatively upstream of the second drain hole 116. This allows for priority draining using the first drain hole 113, while the second drain hole 116 is positioned relatively below the first drain hole 113 along the height direction. When the first drain hole 113 cannot completely drain the gas, the second drain hole 116 can further drain the gas, ensuring a clean environment within the protective box 1.

[0082] Specifically, the sedimentation tank 115 is connected to a second sewage discharge channel 114, which is recessed relative to the lower surface of the main body of the second plate 1102, and a second sewage discharge hole 116 is disposed in the second sewage discharge channel 114.

[0083] In some embodiments, combined with Figure 4 , Figure 5 As shown, the protection box 1 also includes a wire harness conduit 221, which is connected to the protection chamber 119, and the wire harness conduit 221 is adapted to lead out the connection wire harness 22 of the control module 2.
