'Radiator cooling fan' everybody familiar with it, automobile, water dispenser, refrigerator, air conditioner, air purifier, car and so on internal will exist.
The word 'radiator cooling fan, however, is only a general designation and of all kinds of cooling fan, radiator cooling fan of the specific categories you know about it.
Here are - by possessing the cooling cooling fan manufacturer
Chi automotive air conditioning technology bring you more in-depth understanding of 'radiator cooling fan'.
'Radiator cooling fan' is the basic classification according to the mode of power supply: dc supply is called heat dc cooling fan, communication power supply ac cooling cooling fan, these are the foundation, as you all know, today is mainly to introduce the basis it in and out of the air flow divided by the different classification.
The main points, the following four types of the first category, shaft diaspora fan shaft diaspora hot fan blade pushing air in the same direction as the axis (
Parallel to the direction)
Similar to the impeller and the propeller shaft diaspora heat fan, it at work, the vast majority of the flow of air flow parallel to the axis, in other words, is along the axis direction.
Axis diaspora hot fan when the inlet air flow is 0 static pressure free air, the minimum power consumption.
As the air flow back pressure rises when running power consumption will increase.
Axis diaspora hot fan is usually served on the racks to electrical and electronic equipment, sometimes integration on the motor, because of the axis diaspora thermal structure is compact, can save a lot of space, easy installation at the same time, so widely used.
The main advantages are: high flow rate, medium wind pressure, satisfy the general environment of heat dissipation.
The second type, tubular turbine blower fan, it can be called a cross flow cooling fan, it can produce the wind flow of large area, usually used for large surface cooling equipment.
This cooling fan inlet and vent are perpendicular to the axis.
Tubular fan is to use a longer barrel shaped fan impeller, the round barrel the calibre of the blades are great, because of big diameter, to guarantee the overall on the basis of air circulation using low speed, thereby, reduce the noise caused by the high-speed operation.
More used in the elevator, air conditioning, car etc equipment.
Main advantages are: low flow rate, low air pressure, the cooling area is large.
The third kind, mixed flow fans, mixed diaspora hot fan also called diagonal flow cooling fan, the mixed diaspora fan and shaft diaspora hot look from the appearance is no different, in fact, mixed diaspora hot fan inlet is along the axis, but outgassing is along the diagonal direction of the axis and vertical axis.
This cooling fan because of blade and conical casing said, so the air pressure is higher, under the same size and other comparable performance, compared with the shaft diaspora heat fan, centrifugal cooling fan noise is lower.
Main advantages are: high flow rate and the relatively high wind pressure, in order to achieve better cooling effect of the fourth class, centrifugal fan centrifugal cooling fan, blade air moving in a direction perpendicular to the axis phase (
Flow, inlet is along the axis direction, and the gas is perpendicular to the axis direction.
In most cases, the use of shaft diaspora thermal cooling effect can be attained, however, sometimes you rotate it 90 degree if need air discharge or need larger wind pressure, must choose centrifugal cooling fan.
Strictly speaking, fans are belong to the centrifugal cooling fan.
Main advantages are: to change the flow of wind, limited flow rate, high wind pressure.
Above is the radiator cooling fan structure classification, believe everybody through this article has been to 'the classification of the radiator cooling fan 'yourself, if you have not understand, please pay attention to' YiRongChuan '.
More radiator cooling fan knowledge in it, wen ling chi automotive air conditioning manufacturing co. , LTD is dedicated to r&d radiator cooling fan, dc cooling fan, cooling fan, dc fan cooling fan peng brand merchants, radiator cooling fan with complete specifications and product, more than ten years experience in Taiwanese r&d, free proofing, directly or indirectly from two days out of the sample.
