Description

Technical Field

[0001] This utility model relates to the technical field of intake system components for internal combustion engines, and in particular to an electronic throttle valve with a cooling system. Background Technology

[0002] Internal combustion engines typically include a throttle valve, located upstream of the intake manifold and connected to the intake pipe after the turbocharger. It controls the amount of air entering the engine cylinders, and the effectiveness of the electronic throttle directly impacts fuel combustion performance, vehicle power, and ride comfort. Because the intelligent electronic throttle is located after the turbocharger, the turbocharger-output gas is delivered directly to it without cooling. In this case, the temperature of the gas entering the electronic throttle is extremely high, reaching up to 200°C under high engine load. At such high temperatures, temperature-sensitive electrical components in ordinary electronic throttles, such as the circuit board and motor, are prone to failure. Furthermore, prolonged exposure to high temperatures reduces the flexibility of the throttle valve shaft, potentially leading to jamming. Therefore, ordinary electronic throttles cannot withstand prolonged use at high temperatures. Utility Model Content

The intelligent actuator 1 includes a brushless motor. The gear assembly rotates under the drive of the brushless motor, and the valve shaft 202 can rotate under the drive of the gear assembly. Therefore, the valve shaft... 202 drives valve 203 to rotate, thereby controlling the opening degree of valve 203. The intelligent actuator 1 includes an actuator housing 101, within which a first cooling system is installed. A second cooling system is installed within the valve seat 201. The second cooling system includes an upper cooling chamber 204 and a lower cooling chamber 205. The upper cooling chamber 204 is located above the valve hole 200, and the lower cooling chamber 205 is located below the valve hole 200. The upper and lower cooling chambers 204 are connected by an external connecting pipe 206. The intelligent actuator 1 can drive the motor according to EECU commands via the CAN bus to ensure the valve reaches a certain position. The actuator status can also be fed back via the CAN bus, and internal parameters can be diagnosed via messages, such as diagnostics or temperature checks. The intelligent actuator 1 is existing technology and will not be described in detail here.

[0027] like Figure 1 and Figure 4 As shown, the first cooling system includes a first coolant inlet 1011, a first internal cold zone channel 1012 and a first coolant outlet 1013 connected in sequence. A first inlet pipe connector 1015 is fixedly installed at the first coolant inlet 1011 and a first outlet pipe connector 1016 is fixedly installed at the first coolant outlet 1013.

[0028] like Figure 4 As shown, the first internal cold zone passage 1012 includes a longitudinal passage 10121 and two oppositely arranged transverse passages 10122, which are arranged in a U-shape.

[0029] The coolant enters from the first inlet pipe joint 1015, passes through the first internal cold zone channel 1012, and flows out from the first outlet pipe joint 1016. Figure 4 The direction of the S-shape indicates the direction of coolant flow. The primary cooling system prevents high temperatures from affecting the normal operation of the electrical components of the intelligent actuator.

[0030] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the lower cooling chamber 205 of the valve seat includes a lower cooling inlet hole 2051, a first annular cooling channel 2052 and a lower cooling outlet hole 2053 connected to each other. The upper cooling chamber 204 of the valve seat includes an upper cooling inlet hole, a second annular cooling channel 2042 and an upper cooling outlet hole 2043 connected to each other. The lower cooling outlet hole 2053 is connected to the upper cooling inlet hole through an external connecting pipe 206.

[0031] A second inlet pipe connector 2054 is fixed at the lower cooling inlet hole 2051. The two ends of the external connecting pipe 206 are respectively provided with a lower end connector 2061 and an upper end connector 2062. The lower end connector 2061 is fixedly installed at the lower cooling outlet hole 2053, the upper end connector 2062 is fixedly installed at the upper cooling inlet hole, and a second outlet pipe connector 2044 is fixedly installed at the upper cooling outlet hole 2043.

[0032] Coolant enters the lower cooling chamber 205 of the valve seat from the second inlet pipe connector 2054, then enters the upper cooling chamber 204 of the valve seat through the external connecting pipe 206, and exits from the second outlet pipe connector 2044. The second cooling system can prevent high temperatures from affecting the normal operation of the electronic throttle valve shaft and avoid electronic throttle valve failure due to high temperatures.

[0033] like Figure 2 As shown, the valve seat 201 includes a valve seat body 2011, an upper cover 2012 and a lower cover 2013. The upper cover 2012 is fixedly connected to the valve seat body 2011 by bolts, and the lower cover 2013 is fixedly connected to the valve seat body 2011 by bolts.

[0034] Both the lower cooling chamber 205 and the upper cooling chamber 204 of the valve seat are located on the valve seat body 2011.

[0035] The maximum operating temperature of a regular throttle body without water cooling is 110°C. The electronic throttle body with a cooling system in this application can operate at a maximum temperature of 230°C, which can greatly reduce the impact of high temperature environment on electronic throttle body and avoid electronic throttle body failure due to high temperature.
