and panels thereto.
Background Art
[0002] United States patent No.
US 8,468,846 discloses a system and a method for indirect evaporative cooling and for two stage
evaporating cooling having a module and a cartridge. International patent application
publication No.
WO2011/074005 discloses a pre-cooling system and method for pre-cooling air having adiabatic cooling
means.
[0003] United states patent No.
US 6,385,987 discloses heat exchanger for cooling and a pre-cooler for turbine intake air conditioning
having heat exchanger plates.
[0004] In disclosed cooling systems a water is used to intensify a cooling process. In the
mean time use of water reduces life of cooling system elements. Therefore, a protection
system for the cooling devices or heat exchangers should be designed.
Summary of the Invention
[0005] Aim of the invention is reached by developing a protection panel for adiabatic pre
cooling system to be installed on a heat exchanger or a cooling device. The protection
panel comprises a profiled frame, flat frame, a net and a cell panel which are arranged
on each other creating sandwiched protective panel.
[0006] The profiled frame is designed from at least four profiles and the profiles are connected
to each other by angles forming a the profiled frame. Preferably, the profiled frame
is of rectangular shape. It can be made in any other shape to be able to fit to any
heat exchanger. The flat frame is designed from at least four flat bars and is configured
to be attached to the profiled frame.
[0007] The net comprises holes, where a width of each hole is in the range of 4 mm to 100
mm and a height of each hole is in range of 4 mm to 16 mm. More preferably, the width
of each hole is in the range of 6 mm to 20 mm and a height of each hole is in range
of 6 mm to 20 mm.
[0008] The cell panel comprises cells, where a cell diameter of each cell is in the range
of 1000 µm to 7000 µm, more preferably in the range of 1500 µm to 3500 µm.
[0009] The protective panel in assembled state comprises the profiled frame as a base, where
the net is installed, which is followed by the cell panel and above the cell panel
another net is placed forming a sandwiched panel, wherein the flat frame is attached
to the sandwiched panel in order to secure the formed protective panel. After that
all panels are attached together by means of attachment members. All elements of the
panel are secured together by means of attachment members. The attachment members
can be bolts and washers. Instead of bolts and washers, clips can be used.

[0012] A protective panel
1 comprises a flat frame
5, a profiled frame
2, a cell panel
8 and two nets
6 (see Fig. 7). The flat frame
5 comprises four flat bars
6 (see Fig. 2), that are connected together by means of four angles
4. The result is rectangular flat frame
5 (see Fig. 1). A profiled frame
2 is formed in a similar way. The profiled frame
2 is created by connecting together four profiles
3 by means of four angles
4. In the result a rectangular profiled frame
2 is created (see Fig. 3). The next step includes assembling of the panel
1. The net
6 is laid in the profiled frame
2. The a cell panel
8 is added and then covered by another net
6 and above all the flat frame is attached. Therefore, a sandwiched protective panel
1 is created. To secure all said elements a attachment members are used. As attachments
member bolts
9A and washers
9B are used (see Fig. 7). When the panel
1 is assembled it is installed on a cooling device
10 (see Fig. 8). Beforehand, separate panels
1 can be attached together creating one large protective panel (see Fig. 6).
[0013] In another embodiment instead of bolts
9A and washers
9B, clips
9C are used.
[0014] While the inventions have been described with reference to certain embodiments, it
will be understood by those skilled in the art that various changes may be made and
equivalents may be substituted without departing from the scope of the invention.
Therefore, it is intended that the inventions not be limited to the particular embodiments
