Description
Title: New Shroud Design for Engine Cooling Applications [0001] The present disclosure relates to electric DC brush motors. The present disclosure relates in particular to protected electric DC brush motors exposed to different environment conditions that are used for example in cooling systems of motor vehicles.
[00021 Electric DC (direct current) brush motors have a wide range of applications in modern technology. One particular application is the USC of electric DC brush motors for driving a fan of a car engine cooling system. These car engine cooling systems usually comprise a liquid/air heat cxchanger that is cooled by an air flow. In some instances the air flow is generated or accelerated using a fan drivcn by the DC brush motor. The electric DC Is brush motor is in many examples arranged in front or behind the heat exchanger. Similar cooling systems are used in electric vehicles or in hybrid vehicles. The electric DC brush motors are usually placed in the centre of the fan which is directly mounted on the shaft of the electric DC brush motor. Examples for these electric DC brush motors and their arrangement at the heat exchanger can be found in most of the cars distributed today.
[0003] Electric DC brush motors for these applications have to withstand a wide range of temperatures and air humidity and arc often exposed to dirt or dust conditions. The electric DC brush motors have to work reliably under these conditions over extended periods of time to avoid overheating of the car systems in hot conditions.
[0004] State of the art electric DC brush motors comprise a rotor with an armature and a commutator mounted on the shaft. The rotor is rotatably supported by usually one or two bearings inside a metal housing. The metal housing is made using a cylindrical shape and has usually a front end cover and a rear end cover closing the housing at its axial ends (one of the covers may be part of the housing). A stator is arranged inside the metal housing and a separated brush card is arranged at the rear end cover side holding the brushes that interact in use with the commutator.
[00051 Electric DC brush motors have to be cooled by an air flow due to the heat losses generated mainly by the armature. It is important to cool the brushes and the armature in a continuous manner. State of the art motors therefore comprise air inlet holes in the front cover to let a cooling air flow pass from the air entry holes over the brushes on the brush card and over the armature to exit holes at the rear cover. The term front cover defines the side of the electric DC brush motor, at which the fan is mounted onto the shaft. The front cover also corresponds to the driving direction of the car, when the fan is mounted behind the heat exchanger. The electric motor, the fan and the heat exchanger may also be mounted in the opposite direction. The fan generates and air flow for cooling the heat exchanger of the car cooling system. The air flow is also used for the internal cooling of the electric DC brush motor. In state of the art systems, the air flows for internal cooling and for cooling the heat exchanger flow in the same direction. In other words, the air flow generated by the fan is equally passed through the heat exchanger and through the electric motor.
[0006] Corrosion of electrical contacts and the brushes is considercd an important issue for reliability of the electric DC brush motor. The brushes, brush card metal parts and the commutator are directly exposed to air pollution, humidity and other environmental constraints.
[00071 It is an object of the present disclosure to improve electric DC brush motors. It is in particular an object to increase the reliability of electric DC brush motors for cooling systems.
Summary of the Invention
[0008J The present disclosure relates to a mount or shroud for supporting an electric motor. The mount or shroud comprises at least one first arm for supporting the electric motor and the at least one first arm comprises an air guiding channel for guiding air into or out of the housing. The mount or the shroud may be used with a conventional electric motor in a liquid cooling system of a vehicle and may be arranged in front of or behind a liquid/air heat exchanger.
[0009] Guiding air into the housing along the arm provides an air inlet or air pathway into the electric motor, which is independent of the cooling air passing through the heat exchanger and accelerated by the fan. The internal motor cooling air flow passing along the at least one arm may be separated from the external air flow cooling the heat exchanger. Clean air independent from the environment of the cooling system can thus be used for cooling thc electric motor which will increase live time of the electric motor.
[00101 The at least one first arm may have a closed or tube-like cross section forming the air guiding channel. This enables a rigid structure of the at Icast one first arm for supporting the clcetric motor which can bc at the same timc used as a closed channel for guiding the air to or from the housing. While the air guiding channel in the at least one first arm can be used as an air inlet or an air ouflet. In order to reduce pollution of the electric motor and to provide clean and dry air to the ekctric motor, at least one first arm may in is particular be used as air inlet. The housing may further comprise an air outlet. The air outlet may be arranged in an end plate of the housing. The air outlet may be, for example arranged in the rear end plate of the housing, i.e. iii the at the high pressure side of the fan.
The internal motor cooling air flow may than exit the housing of the electric motor in direction of the extemal air flow generated by the fan.
[00111 Alternatively the air outlet in the housing may be arranged at the front end plate of the housing, i.e. the end plate facing towards the low pressure side of the fan. In this case the internal motor cooling air flow exits the housing of the electric motor in a direction opposite to the direction of the external air flow generated by the fan. The fan may comprise a ripped structure producing a depression or low pressure at the air outlets which evacuates the air out of the housing making use of the Venturi effect.
[00121 Alternatively or in addition the electric motor, the mount or shroud may comprise at least one second arm comprising an air outlet channel. The at least one second arm may Jo be used in addition to the air outlet in the front end plate or rear end plate of the housing.
[00131 Alternatively the housing may have no other opening and the at least one first arm may be used for air inlet while the at least one second arm is exclusively used for air outlet.
A sealed housing is obtained which may allow driving the electric motor in wet or in dirt or in dust conditions.
[0014] The expression at least one first arm intends that electric motor may be supported by one, two or more first arms which serve in parallel as air inlet. This allows adjusting the quantity of air transported towards the electric motor. The first arms are used as air inlet and the air usually leaves the electric motor through openings in the housing. It is, however, also possible to use one or more arm as air outlet. Generally air guiding channels, i.e. air inlet channek and air outlet channels can be arranged in the arms depending on the amount of air that should be transported toward and away from the electric motor.
[0015] The arms may be arranged substantially radially to a shaft of the electric motor.
One or more of the at least one first arm and/or the at least one second arm may also be arranged differently. For example a tangential arrangement of an arm with respect to the housing, i.e a lateral wall of the housing of the electric motor may influence the direction of the air inlet or air outlet into or out of the electric motor. Furthermore a tangentially arrangement of the arm may be useful in taking of momentums generated by the fan and electric motor when rotating.
[0016] The air guiding channel of the at least one first arm may comprise a filter for filtering air passing through the air guiding channel. This filter allows to further cleaning the air inserted into the electric motor.
[0017] The fiher may be in the form of at least one deflection inside the air guiding channel in particular a plurality of offset deflections forming a labyrinth have been shown to be very useful for filtering humidity, pollution and dust from the air passing through the air guiding channel. Plastics materials may be used for the at least one or more deflections.
The same plastics material may be used for forming the at least one first arm and/or the at least one second arm and the one or more deflections may be integrally formed inside the at least one first arm and/or the at least one second arm.
[0018] A galvanic electrode, in particular a galvanic anode may be arranged inside the air guiding channel. This galvanic electrode allows efficient cleaning of the air passing through the air guiding channel.
[0019] The housing of the electric motor, the mount or shroud may further comprise a drain for evacuating liquids from the inside of the housing. The drain may be arranged such that it is in the bottom side when the electric motor and the housing are mounted in the cooling system. This may be particular usefril in humid or wet conditions where the filtering and the plurality of deflections promote condensation of liquid at the walls which can then be transported to the outside using the drains.
[0020] The electric motor, the mount or shroud may be used in no cooling systems of a ear and may be placed in front of or behind known heat exchangers.
Detailed Description
[0021] The invention may be better understood when reading the following detailed description of examples implementing the invention which are given with respect to the attached figures in which [0022] Figure 1 shows an example of the arrangement of a electric motor driven fan in a cooling system of a ear; [0023] Figure 2 shows how an electric motor can be mounted in a shroud; [0024] Figure 3a to c show the assembled electric motor shroud arrangement; [0025] Figure 4a shows a cross section through the electric motor mounted in a shroud; and Figure 4b shows the electric motor 4a with a fan mounted thereon; and [0026] FigureS shows a possible design of a fan; Detailcd descrintion [0027] The fbllowing description describes examples of the invention and different aspects thereof in more detail. While several features of the present disclosure are implemented in the described examples, it is to be understood that the invention is not limited to those combinations and that a person skilled in the art will select those features that are appropriate for a specific application.
[0028] Figure 1 shows a front part of a car in which an electric fan 9 is held by a shroud behind a heat exchanger 105. The ear 100 has a driving direction 101 and all directions given herein will refer to the driving direction 101 of the car. The heat exchanger 105 of a cooling system is arranged in front of a motor block 104. The cooling system and the evaporator 105 may be a water based cooling system as known in the art. Any other refrigerant may be used instead of water. The heat exchanger 105 may be an air/liquid heat exchanger that is cooled by an external air flow 102 which may arise when the car is moving. This external air flow 102 crosses the air liquid heat exchanger 105 and cools the liquid inside the heat exchanger 105. II' the air flow generated by the movement of the vehicle 100 is not sufficient, a fan 9 may be actuated in order to accelerate the external air flow 102. The fan 9 may be arranged behind the heat exchanger 105 in the external air flow 102, as shown in the example of Figure 1. In other words the external air flow 102 first passes the heat exchanger 105 and subsequently the fan 9. The fan is driven by an electric motor 10 which holds the fan on its shaft. A shroud structure 560 holds the electric motor and thereby the fan 9 in place and provides some protection from the turning fitn 9.
This structure is known in the art and used in many vehicles. While the further description refers to this particular arrangement of the heat exchanger 105, fan 9, electric motor 10 and shroud 560, other arrangements are possible as well. For example the fan 9 and the electric motor 10 can be arranged on the front side of the heat exchanger 105 thus blowing the air through the heat exchanger, and/or the heat exchanger, fan and electric motor can be arranged differently with respect to the driving direction 101 of the ear 100.
[00291 Figure 2 shows an exploded view of a shroud or mount 500 into which an electric motor 10 can be mounted. The mount 500 comprises a sealing ring 510 for sealing a portion of the electric motor 10 to the mount 500 as will be explained later. The mount or shroud 500 comprises a motor reception portion 510. The motor reception portion 510 has a substantially circular shape and is adapted to locate the electric motor 10. The electric motor may have fixation means 86 by which the electric motor 10 can be held in place inside the mount or shroud 500. The mount or shroud 500 further comprises a shroud or motor cover 580 and a plurality of arms 556, 558. In the example shown four arms 556, 558 are provided with different shape and arrangement on the motor reception portion 510.
Other number, different angles and/or arrangement of the arms 556, 558 may be used in accordance with the requirements of the specific application.
[0030] The electric motor 10 shown in Figure 2 may be an electric motor as known in the art. The electric motor 10 may be a DC brush motor. The electric motor comprises a is housing 50 with a cylindrical lateral wall 54. The housing 50 further comprises a base or front cover 52 attached to the later wall 54. The front cover 52 has a central opening for the shaft 29 of the electric motor and a plurality of air outlet holes 528. The housing is closed by a rear cover 80. The rear cover comprises air inlet holes 82.
[00311 The electric motor 10 is placed inside the motor receiving portion 510 of the shroud/mount 500 and the mount can be closed by air sealing ring 505. The air sealing ring 505 may also be used for positioning, fixing and holding the electric motor 10 in place. In this case a fixation of the electric motor into the motor reception portion 510 of the shroud 500 can be avoided, economising one assembly step.
[0032] If the electric motor and the sealing ring 505 are mounted to the motor reception portion 510 of the shroud 500, the electric motor 10 is fixedly held in place. The rear cover and a rear portion of the lateral wall are enclosed in the motor reception portion 510 sealed with a sealing ring 505. Due to the air-tight motor cover 580 of the shroud 500 an air inlet volume is formed between the motor cover 580 and the rear cover 80. The arms 556, 558 comprise air guiding channels 557 through which air can be guided inside the volume generated by the motor reception portion, the motor cover 580 and the electric motor 10. All cooling air entering the electric motor 10 through air inlet holes 82 passes through the arms 556, 558.
[0033] Figure 3a shows a top view with assembled shroud 500 with electric motor 10 in viewing direction from the heat exchanger 105 or fan 9. The arms 556, 558 can be arranged in different angles at the motor reception portion 510 of the shroud 500 as illustrated in Figure 3. The arms 556 can be radially arranged with respect to the shaft of the electric motor 10. The arms 558 can also be arranged at an angle with respect to the radial axis.
[0034] Air outlet holes 528 are visible and will be explained in more detail below.
[0035] Figure 3b shows the assembled shroud 500 in a perspective view showing the motor cover 580 and Figure 3c show the same view as Figure 3b with a transparent motor cover 580 and thus sowing air inlet openings 82 provided in the rear cover 80 of the electric motor 10.
[0036] The shroud or motor reception unit 500 may thrther comprise a drain 590 which is arranged in the lower side of the motor reception portion, when the shroud and the electric motor are mounted in a vehicle 100. The drain 590 may serve for evacuating liquids from the inside of the electric motor 10 or the seal volume between the motor receiving portion 510 and the sealing ring 505.
[0037] Figure 4a shows a cross section through the shroud 500 and the electric motor 10 of the previous Figures. The electric motor 10 is placed inside the reception portion 510 of mount!shroud 500 leaving an air gap between the motor cover 580 and the rear cover 80 of the electric motor 10. The arms 556 are fluidly connected to this air gap by an opening 557 allowing an internal cold air flow to pass through the arms 556 behind the rear cover 80 and into the gap between the rear cover 80 and the motor cover 580 of the shroud 500. Air inlet openings 82 are provided in rear cover 80 of the electric motor 10 which provide access to the inside of the electric motor from the gap. Cold air C of the internal air flow enters the inside of the motor 10 through this air inlet openings 82 and passes over brushes 66 and an armature 34 towards the air outlet holes 528 in the front cover or base 52 of the bowl shape portion 50. As indicated in Figure 4a, the air outlet holes 528 face towards the side in which the fan 9 is arranged on shaft 29 and thus opposite to the direction of the external air flow 102 if the fan is arranged behind the heat exchanger as shown in Figure 1.
[0038] Figure 4b shows the electric motor 10 and shroud 500 of Figure 4a with a fan 9 mounted on the shall 29. The fan 9 has an inner housing 91 with a lateral wall 913 of substantially cylindrical shape and a fan front cover 918. A plurality of cooling ribs or motor cooling blades 92 is arranged inside the inner housing 91 of the fan. When the electric motor and consequently the fan 9 is rotating, the cooling ribs 92 generate a depression and an air flow out of the inner housing 91. Alternatively or in addition, the external flow 102 generates a depression by the well-known Venturi effect which evacuating the hot air H and the inner flow out of the itmer housing 91. Fan blades 93 are provided on the outside of the inner housing 91 to generate or accelerate the external air flow 102.
[0039] Figure 5 shows the fan 9 in more detail. The blades 93 arc fixed between the inner housing 91, in particular between the lateral wall of the inner housing 91 and an outer ring 95. While the Figure 5 and 4b show cooling ribs 92 for generating a depression and transporting the air from the air outlet holes 528 to the outside, the cooling ribs 92 may be omitted and the depression may be simply generated by the bypassing air flow 102 based on the Venturi effect.
[0040] It should be understood that the examples of the present disclosure given up are purely illustrative and that features described in an example can be combined in any way with example known with respect to other examples. For example a person skilled in the art may combine the arms with shroud 500 of Figure 2 are vice versa. Furthermore the orientation for the brushes 66 inside the electric motor 10 may be swapped facing to rear cover 80 as shown in Figures 2 to 4b or facing towards the fan. Other features can also be combined or used separately.
