ABSTRACT
During major part of the year, various climatic conditions, like heavy rain, extreme hot or
cold, make driving a two wheeler uncomfortable and prone to accidents. In order to prevent
such casualties we made a stiff casing in form of cabin with air conditioning within.
Making a covering for the driver and conditioning the air within it will not only protect
him/her from difficulty caused while driving due to adverse climate but it will also help
him/her concentrate better.
Use of refrigerants (Freon, ammonia…) can get maximum output but one of the major
disadvantage is harmful gas emission and global warming, this problem is overcome by using
thermoelectric module (Peltier effect). This technique will result in zero emissions.
As the cooling units are of small size, silent, contains no liquids or gases and have no moving
part hence a long life. It is very simple to control the rate of cooling by adjustment of the
current, the response to changes in the supply is very rapid, while reversal of the direction of
the current transforms a cooling units into a heater with COP in excess of unity.

INTRODUCTION
A thermoelectric (TE) cooler, sometimes called a thermoelectric module or
Peltier cooler, is a semiconductor-based electronic component that functions
as a small heat pump. By applying a low voltage DC power source to a TE
module, heat will be moved through the module from one side to the other.
One module face, therefore, will be cooled while the opposite face
simultaneously is heated. It is important to note that this phenomenon may be
reversed whereby a change in the polarity (plus and minus) of the applied DC
voltage will cause heat to be moved in the opposite direction. Consequently, a
thermoelectric module may be used for both heating and cooling thereby
making it highly suitable for precise temperature control applications.
We have fabricated frame on two wheeler made of hollow steel pipe and
provided covering with polystyrene covers and wind shield to minimize the
flow of air in the cabin, and we have also mounted Peltier cooler on to the
frame to provide comfort to passengers while riding.
METHODOLOGY
The chapter gives the information about the methodology being adapted to complete the
project. Starting from the testing of Peltier module assembly to fabrication of Peltier cooler ,
bike frame and their assembly.
3.1 Peltier cooler
The Peltier cooler is designed and fabricated as to meet the requirements in various
seasons. The fabrication and construction details are as follows:
Peltier cooler consist of:
2 Peltier modules used to cool the driver’s cabin and maintain the temperature.
2 Big heat sinks are used to remove the heat generated by Peltier.
3 Exhaust fans to create suction so that air entering the cooler strikes the cold fins
and then pulled out into cabin.
Peltier modules were stick to the big heat sinks on one side and with fins on the other
side with the help of thermal paste. After adding some epoxy the whole setup is fixed
to the wooden box with the help of 8 bolts.
We also attached aluminium sheets inside the cooler so that the cooling inside the
box is maintained.
Exhaust fans are mounted inside the cooler to force out the cool air within into the
cabin.
3.2 Frame
The frame is made up of circular hollow stainless steel pipe because they are best
suited in structural efficiency to resist various loading conditions.
Firstly the pipe is bend into the required geometrical shape, by measuring vehicle
dimensions and drivers comfort, from the shape obtained by modelling.
After bending cross members are attached to the main side members by welding.
After the shape is achieved the welding is made permanent.
Windproof and waterproof covering is cut in conjugate shape of frame and attached
to it with the help of nut and bolts.
Cooler is attached to the frame and then the whole frame cooler assembly is mounted
on the bike with the help of clamps and nut bolts.
Windshield is attached at the front portion in the end so as to minimize drag and air
leakage.
MODELLING AND ANALYSIS
The chapter shows the modelling of project done to virtually obtain the prototype of bike
frame that we were going to fabricate and also to check its reliability in real environmental
conditions it was tested on CAE software.
Modelling of project
After measuring the vehicle dimensions, handle swing and leg space of the passengers
modelling was done in CREO parametric software.
The isometric view of frame is shown below:
Fig. 4.1.1 Design in CREO
Analysis in Ansys Workbench
After proper preparation of model in CREO parametric software, model is imported into
Ansys(16.0) software and different analysis such as static structural , CFD were performed
and maximum stresses, deformation and pressure was obtained. Bumping load of 3000N was
applied at the frame body and fix support was applied at the frame ends. The values obtained
were compared with the theoretical values and factor of safety of 1.5 was obtained as ultimate
tensile strength of structural steel is 550MPa

FABRICATION
The Photographs of the Peltier cooler and fabrication of frame has been shown below. Also
the pictures shows the compatibility of two passenger’s comfortability in the two wheeler.
Fabrication of Peltier cooler
Complete assembly of Peltier modules with heat sinks and exhaust fans were made and the
all the devices were connected in parallel with a 12V D.C battery.

Fabrication of Bike Frame:
After the bending and welding of pipes and mounts, foldable transparent shed and
windshield was attached after which the Peltier cooler was mounted on the upper members.

Advantages of project
Provide comfort to the driver and passenger in two wheeler during adverse weather
conditions.
Prevention from loo winds, rain, dust etc.
High reliability which do not produce constraints while riding.
Temperature within the cabin is maintained for suitable driving atmosphere.
Comfortable atmosphere during winter as major problem during cold weather is cold
winds.
Foldable curtains are used so that during pleasant outer atmosphere curtains can be
folded and cooler can be switched off.
Good head space and leg room is being provided.
Battery is charged by alternator of battery hence power consumption by cooler is not a
problem.
Covering can also be made from fiber sheet for rigid side structure.
Solar panels can also be installed for battery charging.
Hot side of the Peltier can be used to provide warm air during cold seasons.
Wipers can be installed for rain.
Other means of cooling such as evaporation cooling can be used as Peltier is less
efficient and power consuming.
More packed and leak-proof covering can be fabricated for efficient cooling.
The cabin can also be heated and cooled simultaneously by means of vortex tube
refrigeration by making an arrangement of compressor that runs by bike battery
power.
Use of cooling and heating jackets-such as Peltier jackets and vortex tube air jackets
can also be used for providing comfort in adverse weather conditions
Refrigeration by expansion of air or throttling of gas can also be used.
