Description

Fan motor assembly
Technical field
Present invention relates in general to fan motor assembly, more specifically, relate to the fan motor assembly of the fan that comprises two or more settings adjacent one another are.
Background technique
In recent years, high side circuitry has been installed in the electrical equipment, and these electrical equipments can produce a large amount of heats.Electrical equipment has been equipped with a plurality of fans usually and has come active heat removal.
Still in recent years, wish that electrical equipment has the size that reduces, minimize its size so that electrical equipment may be designed to be.As a result, the space that is used to hold fan motor assembly also is restricted.
Fan comprises the lead that is used for to its power supply.When a plurality of fans place in the shell of electrical equipment, be set to the periphery cabling of the lead of the fan farther at the fan that is set to more close power supply apart from power supply.Yet, consider the efficient layout of other assemblies in the electrical equipment shell, the size that must reduce fan housing (housing) is to guarantee to be used for the space of lead.Usually, when reducing fan housing size big or small, also reduced the size in air channel.Thereby, reduced the size of blast fan, this has caused deterioration air-flow and the cooling characteristics of fan.
Summary of the invention
In order to overcome the problems referred to above, the preferred embodiments of the present invention provide a kind of fan motor assembly, and this fan motor assembly comprises a main fan and at least one secondary fan.The lead that connects described at least one secondary fan and external power supply at the air inlet side of main fan or the surperficial upward wiring of air outlet side, is drawn main fan then.
According to another preferred embodiment of the invention, each fan all comprises and is positioned at the outer position of air-flow path and is positioned at the air outlet side of fan or the lip part of air inlet side.
According to another preferred embodiment of the invention, the lead that connects main fan and external power supply is drawn main fan, is tied together with the lead of secondary fan simultaneously.
Because above-mentioned particular structure does not need to guarantee to be used for the space of conductor loop around the fan motor assembly cabling.Therefore, do not need to reduce the Inner Dimension of outer cover or the outside dimensions of impeller.As a result, fan motor assembly can be installed in the restricted clearance, keeps suitable air-flow and cooling characteristics simultaneously.
When describing the preferred embodiments of the present invention, be used to explain the position relation between each parts and the word of direction, as upper and lower, left and right, upwards, downwards, top and bottom, represent that just the position in the accompanying drawing concerns and direction.These words do not represent to be installed in position component relation and the direction in the physical device.
