Description
TITLE
AIR COOLER WITH UNIQUE SYSTEM OF AIR DISTRIBUTION, AND AIR DEFLECTIONS
FIELD OF THE INVENTION
The invention relates to an air cooler system with a specific configuration wherein the deflectors at the exit of involutes and the motorized verticals louvers is able to give almost even distribution across the opening in the front panel. Further the invention also deals with the angular aesthetical curved surface and the configuration thereof which enables the air throw close to 98% of the width of the cooler.
BACKGROUND OF THE INVENTION
In air coolers generally there are systems which provides for normally a frame, air inlet, air outlet and a motor. This consists of housing and rectangular frame and a separator. The air enters the cooler from the air inlets flows through the cooler and in return does the air distribution. This mechanism is very common however in the process there are lots of impediments as loss of air distribution and air pockets are created which reduces the air cooling and the outcome of air coolers is not efficiently utilized.
The present invention is an attempt to meet the need of industry by providing an appropriate system in the air cooler mechanism in such a way that it increases air distribution evenly and at a rate of 98% at the width of the air cooler system.
OBJECTS OF INVENTION
It is one of the objects of the invention to have maximum air distribution with the help of configuration at the surface of the front panel on both vertical sides and the opening to help the air to change its direction and thereby achieving preferably air throw of at least not less than 98%o of the physical width of the air cooler.
It is yet another object of the invention to provide for a configuration of placing the deflectors at the exit of the involutes and behind the motorized/ manual vertical louvers is able to give
almost even air distribution across the opening in the front panel.
It is yet further object of the invention to provide for an effective system to overcome ineffective air pockets created in the air cooling system with the help of deflectors mounted at the exit help to divert the air throw evenly across the opening in the front panel and does not allow the ambient warm air to get sucked in. The fixed flanges added as separators on the vertical curved surfaces in the front panel further direct the air flow out of the front panel.
DETAIL DESCRIPTION
The invention is and more specifically described in reference to the accompany drawing and the description provided as below
Air distribution
A centrifugal fan is a mechanical device for moving air or other gases. The speed of air stream is increased with the rotating impellers. They use the kinetic energy of the impellers or the rotating blade to increase the pressure of the air stream which in turn moves them against the resistance caused by ducts, dampers and other components. Centrifugal fans accelerate air radically, changing the direction of the airflow. They are sturdy, quiet, reliable, and capable of operating over a wide range of conditions. At a constant fan speed, a centrifugal fan will pump a constant volume of air rather than a constant mass. This means that the air velocity in a system is fixed even though mass flow rate through the fan is not.
It has a fan wheel composed of a number of fan blades, or ribs, mounted around a hub. The hub turns on a driveshaft that passes through the fan housing. The air enters from the sides parallel to the fan blades and turns 90 degrees and accelerates due to centrifugal force as it flows over the fan blades and exits the fan housing resulting in air throw.
At a constant fan speed, the centrifugal fan pumps a constant volume of air which is almost evenly distributed across the opening outlet in the front panel. The angular aesthetical curved surface in the front panel on both vertical side and the opening in front further divides the air to change its direction. This configuration achieves air throw close to 98% of the physical width of the air cooler.
Angling and air positioning
The air entering the blower housing accelerates due to centrifugal force as it flows over the fan blades and exits the housing. At the involutes exit deflector 'A' of ht 138mm and width 60mm and deflector 'B' of ht 138mm and width 41.5mm are mounted at an angle with reference to the blower to achieve maximum deflection of air. Deflector 'A' is positioned at ½.5 distances between the involutes and the blower outer diameter and at an angle of 50.8 deg with reference to the blower centre. This deflector diverts the air towards the left side of the front panel. The min angle being 15 deg and Max being 100 deg with the height equals to the height of the involutes exit. Deflector 'B' is positioned at 1/4* distance between the involutes and the blower centre and at an angle of 30.5 deg with reference to the blower centre. This deflector diverts the air towards the right side of the front panel. The min angle being 5 deg and Max being 115 deg with the height equals to the height of the involutes exit. The width of the deflector is kept at 2/3rd of that of deflector A. These positions can be changed and additional deflectors added based on the airflow distribution required with reference to the opening in the front panel for air exit. This configuration of placing the deflectors at the exit of the involutes and behind the motorized / manual vertical louvers is able to give almost even air distribution across the opening in the front panel.
Air pockets
The involutes exit has been angled out to meet the opening in the front panel. The air throw is effective in the outward direction of rotation and this air throw reduces when the blower enters the involutes limiting the air throw up to 2/3rd of the opening of the involutes. Further extended involutes shroud limits the air throw to be directed out of the opening in the front panel. To overcome any in-effective air pockets created, deflectors mounted at the exit help to divert the air throw evenly across the opening in the front panel and does not allow the ambient warm air to get sucked in. Secondly minimal fixed flanges added as separators on the vertical curved surfaces in the front panel further direct the air flow out of the front panel.
SUMMARY OF INVENTION
It is one of the embodiments of the invention to provide for system on the front panel of the air cooling device whereby a configuration is design on both the sides and opening of the panel to achieve a air throw of not less than 98% across the width of the air cooler.
It is also another aspect of the invention whereby the deflector are configured at the exit of the involutes and behind lowness to give even distribution of air in the from the panel . The said deflectors also helps in providing an effective system to overcome in effective air pockets created in air cooling system.
