Description

Has the fan component that is installed in the guard shield on the protector
Technical field
A kind of fan component of relate generally to of the present invention relates more specifically to a kind of fan component with the guard shield (shroud) on finger guard of being installed in (finger shield spare).
Background technique
Motor comprises diesel engine as known in the art, petrol engine, gaseous propellant engine and other motor, when work owing to fuel combustion produces heat.The circulation liquid coolant remains on motor in the safe operating range to take away heat from motor in motor.Be configured to receive and circulate for from freezing mixture, taking away heat, can using from the radiator of the freezing mixture of motor.Can make air pass radiator by the cooling fan suction air from the freezing mixture of the radiator of flowing through, to take away part heat.Freezing mixture to small part is cooled off and return engine in this way.
Usually the fan shroud that the blade that surrounds cooling fan is set between cooling fan and radiator is crossed radiator with the aid in guide air communication.In some conventional layout, described guard shield can be mounted to and make this guard shield move with radiator, and fan is mounted to this fan is moved with motor.This mounting arrangements structure can allow guard shield and fan to move relative to each other, and may require bigger allowance to prevent that guard shield from contacting with fan.That is to say that need big slit to prevent that the top of fan blade from contacting with fan shroud, described contact may damage one or more parts and/or produce noise between the top of fan blade and fan shroud.Because very big in the top and the gap between the fan shroud of fan blade, fan cooled efficient can reduce.
The U.S. Patent No. 4,552,160 (" ' 160 patent ") of authorizing people such as Speers discloses an example of the less cooling fan in gap between fan blade and fan shroud.Thereby ' 160 patent disclosures be configured to compensate relative movement between motor and the radiator and prevent fan and the contacted a kind of fan shroud structure of guard shield and configuration is installed.' 160 patents comprise a kind of motor, are installed in fan, the radiator on the motor and are connected to motor and the shroud structure of radiator.But radiator and motor mechanism cause relative movement.' 160 patents also comprise and a kind ofly are installed in the fan on the motor and are connected to motor and the shroud structure of radiator.Particularly, in a kind of form of implementation, the guard shield of ' 160 patents comprises glass fibre guard shield and ball sealing (bulbous seal).It is the end of rectangle basically that the glass fibre guard shield has, and this end is attached in the relative annular venturi portion.This venturi portion is secured on a plurality of supports that are installed on the motor.Described rectangle end or box-like outer shield are fixed on the ball sealing to adapt to the relative movement between motor and radiator.
The shroud structure of ' 160 patents is can be in fan blade and guard shield intermarginal to provide little gap.Yet this structure is vulnerable to unnecessary wearing and tearing.For example, when motor and radiator relative movement, ball sealing can not adapt to bigger motion, the situation very big as the torque of motor.In addition, this relative movement may cause the ball sealing friction and extrude from radiator and guard shield.In addition, because the guard shield of ' 160 patents need adapt to the relative movement of motor and radiator, so that the gap between fan blade and the shroud structure may be than hope is big.In addition, the complexity of parts, need hardware to fix parts and because relative movement and may make the cost of shroud structure improve and need to the wearing and tearing of parts to safeguard.
Disclosed fan component is intended to solve above-mentioned one or more problems.

Industrial applicibility
Disclosed fan component can be arranged in the machine of any heating, and can be used for various application.Particularly, fan component can allow the gap minimum between the venturi portion of fan top and fan shroud to reduce undesirable wearing and tearing and noise simultaneously.The following describes the work of fan component 118.
When machine 100 work, motor 102 can produce heat and need cooling.Heat is delivered to freezing mixture from motor 102 but the freezing mixture percolation is crossed motor 102.Leave motor 102, freezing mixture can pass heat exchanger 116.Circulation time in the pipe of freezing mixture in heat exchanger 116, the configuration of heat exchanger 116 can promote from freezing mixture environment heat transfer towards periphery.Fan 200 can produce the air-flow that passes heat exchanger 116, the heat transfer of auxiliary freezing mixture during the pipe in freezing mixture passes heat exchanger 116 thus.The air-flow that is passed heat exchanger 116 by fan 200 suction can contact with the outer surface of the pipe that is loaded with freezing mixture of heat exchanger 116.Freezing mixture is cooled at least in part by this way, and return engine 102 then.
Fan shroud 202 can help steering flow to pass heat exchanger 116.As shown in Figures 2 and 3, the size of the venturi portion 400 of fan shroud 202 and shape can be configured to make between venturi portion 400 and the fan top 220 and keep less clearance.With such gap, can extract more air by fan 200, improve fan efficiency thus.Because fan 200 and fan shroud 202 can not relative movement, fan top 220 contacts damage and/or the noise that fan shroud 202 causes during operation so fan component 118 can reduce.The layout of fan component 118 can be favourable, because the design of simplifying can be easier to assembling and cost of production is minimized.Particularly, wherein fan shroud 202 via finger shield spare 204 be fixedly attached to mounting structure 206 and mounting structure 206 also regularly the layout of supports fans 200 can reduce tolerance stack (that is the manufacturing tolerances of the parts of combination).
It should be apparent to those skilled in the art that under the situation that does not deviate from scope of the present invention and can make various modification and modification fan component of the present invention.Under the situation of considering specification and disclosed fan component being put into practice, other form of implementation is conspicuous to one skilled in the art.Illustrate and described embodiment only as example, actual range of the present invention is then limited by following claim and equivalent thereof.
