BACKGROUND OF THE DISCLOSURE
Thermal Electric Generator cell can generates electrical power from heat. In
fact,
thermal electric generator cell has two sides that one side is connected to
source of
heat and the other side to a cold source. It generates electrical power when
heat flows
from hot side to cold side through the cell. The problem with thermal electric
generator
cell is that they do not generate large amount of power and they are
expensive. To get
more out put power it is needed to connect some thermal electric generator
cells in
serious or/and parallel. But cost of assembly of the cells together and
getting the
maximum power out of them is to high cause such as not precision dimensions in
cells.
In addition, thermal electric generators have not been used in some of the
main source
of heat waste so far.
Thermal electric generator cell is used in some applications in different
industries such
as vehicles, portable devices, aerospace and etc, but they have never used in
some
heat sources devices that are used in our life and unfortunately even the most
efficient
one has still low efficiency and they waste energy through heat from their
exhaust flue
or from their body. Some of these heat sources that are often overlook and
untapped
are furnaces, water heaters (includes boilers and water heater with tank &
tankless) and
ovens (bakery, pizza and heat treatment oven/furnace).
Therefore, this innovation is to solve above problems and introduce a new way
of
assembly of the thermal electric generator cells together and make a thermal
electric
generator power device that can reduce the cost of the device and the device
can be
suitable for using in all applications such as above applications. In
addition, this
innovation is to generate electrical power from some sources of heat that
never were
used in the past (above application).

Description
The invention relates to a device that can generate electrical power from heat
in any
thermal system applications such as furnaces, water heaters (includes boilers
and water
heater with tank & tankless) and ovens (bakery, pizza and heat treatment
oven/furnace). This devise is designed in a way that can reduce the
manufacturing cost
and increase efficiency and performance of Thermal Electric Generator Device.
Thermal electric generator cells have not been used in furnaces, water heaters
(includes boilers and water heater with tank & tankless) and ovens (bakery,
pizza and
heat treatment oven/furnace). In addition, the new design and manufacturing
method of
the thermal electric generator device has never been used on the above
applications
nor in any other industry or any other thermal system applications that
generate heats.
I have find a way to use thermal electric generator device in a way that the
cold side of
thermal electric generator cell can directly contact with water/coolant for
cooling down
and use hot exhaust flue or/and heat source to heat up the hot side of thermal
electric
generator cell. Using water in the new device not only reduce to manufacturing
cost, but
also increase the efficiency of thermal electric generator in furnaces, water
heaters
(includes boilers and water heater with tank & tankless) and ovens (bakery,
pizza and
heat treatment oven/furnace) or in any other source of heat in any other
applications in
different industry.
In this invention, below main components are used:
- Top housing
- Thermal electric generator cell
- Heat sink
- High temperature silicon
- Thermal past
Depends on the require output power from the thermal electric generator,
several
thermal electric generator cell can be used in one device by connecting the
cells to each
other in series or/and parallel.

The thermal electric generator cells Fig. 5 will be attached to each other
with applying of
high temperature silicon between the thermal electric generator cells 6 and 7.
In, fact by
attaching them to each other with silicon we make them as one piece of thermal
electric
generator and seal them together to prevent leaking water/coolant between the
thermal
electric cells. In addition, every single cell will have the ability to sit
perfectly on hot side
of aluminum regardless of any impact from the thickness of the other cells.
It is important that each thermal electric generator cell sits on the heat
sink Fig. 1 with
proper assembly force to assure proper connection between the heat sink and
the
thermal electric generator cell's hot side. By using spring Fig. 8 we can
achieve the
require assembly pressure. Therefore, for every cell one spring is used to
push every
cell down to the heat sink and provide the proper assembly force. Each spring
should sit
in the middle of the thermal cell 8 in Fig. 10 for better pressure
distribution. In fact, the
spring will be located between the thermal electric power cell Fig. 5 and top
housing Fig.
3 as it is 9 shown in Fig.12.
As it was mentioned in above, this device will be cool down directly with
water. It means
cold water will be flowing on the thermal electric cell's cold side. To do so,
cold water
will enter from 1 in Fig. 3 and exit from 3 in Fig. 3. Wall 5 in Fig.4 is
designed to
enhance cooling of the cells by dividing the top housing Fig. 3 to two
separate channels.
In fact, once the top housing Fig. 3 is assembled, the wall 5 will sits on to
the silicon 7
and seal and separate the top housing to two channels. Therefore cold water
enters
from 1 and flows down 10 and moves in direction of 11 to cool down all cells
12. Then
water reach to 13 and since at point 13 the wall 5 is cut as shown at 4 in
Fig.4 water will
move to the other channel and cools down the other cells in its direction to
exit from 3.
Thermal electric generator cells can be connected to each other in parallel
and series it
depends on the design and required output power. And the output wire will exit
from 2 in
Fig.3. All wiring should be hidden and sealed under silicon to prevent any
electric short
circuit

Thermal paste needs to be used to compromise any flatness imperfection between
the
heat sink and thermal electric generator cells.
A way of assembly of the thermal electric generator device Fig. 11 is to apply
thermal
grease on heat sink and on the thermal electric power cells (hot side). Place
the thermal
electric power cells (hot side) on heat sink Fig. 10. Note, before placing the
cells on heat
sink we should apply high temperature silicon 6 between the thermal electric
cells 9 to
make sure cells are attached to each other and they are sealed. After placing
the cells
on the heat sink we place spring 8 on top of every cell as shown in Fig. 10.
And then
place the top housing Fig. 3 on top of assembled components Fig. 10.
Every thermal electric generator device Fig. 11 can be installed as a single
device on
above mentioned heat source or we can attach a few of single thermal electric
generator device to each other in different shapes like square, rectangle,
triangle or etc
for instance Fig. 14. And install them on furnaces, water heaters (includes
boilers and
water heater with tank & tankless) and ovens (bakery, pizza and heat treatment
oven/furnace). In fact, the hot exhaust gas can enter from 14 in Fig. 15 and
heat up the
devices and then exit from 15 in Fig. 16.
Use of the thermal electric generator device in water heater/boiler;
As show in Fig. 18, the thermal electrical generator power device 24 (refer to
Fig. 14 &
11) will be installed where the hot exhaust flue travels 18 to out of water
heaters. In fact,
the exited hot exhaust flue will enters from 14 and it exits from 15 (refer to
Fig. 15 &16).
This will heat up the full thermal electrical generator power 17. The cold
water (city
water) will enter into the full thermal electrical generator power 20 to cool
down the unit
and then exit from the thermal electrical generator power device 21 and it
goes to the
water heater device 19. The thermal electrical generator power device warms up
the
water before water goes into water heater/boiler and then the water
heater/boiler use
the incoming hot water hot it up and then water will exit from the water
heater 22 for
use.

Use of the thermal electrical generator devices in furnace;
As show in Fig. 19, the thermal electrical generator power 24 (refer to Fig.
14 & 11) will
be installed where the hot exhaust flue travels 25 to out of the furnace. In
fact, the
exited hot exhaust flue will enters from 14 and it exits from 15 (refer to
Fig. 15 &16).
This will heat up the thermal electrical generator power device 24. For
cooling down the
full thermal electrical generator Power unit 24 we need to use a closed
cooling system.
It means water/coolant will travels between of the thermal electrical
generator device 24
and cooling radiator 30. In fact, water/coolant will be pumped 27 from the
radiator 30
through pipe 26 to the thermal electrical generator device unit 24. And then
the
water/coolant goes back to the radiator 30 through pipe 28 to be cool down by
the
radiator.
The radiator should be installed in the furnace where the furnace sucks cold
air into the
furnace (intake vent) 29. In fact the radiator should be installed where the
cold air enters
into the furnace from 29 and furnace heats the cold air and the cold will exit
from 23.
This will cool down the radiator without adding any other fan.
Use of the thermal electrical generator device in oven/heat treatment furnace;
As show in Fig. 20, the thermal electrical generator device 31 (refer to Fig.
14 & 11) is
installed on the hot exhaust vent in ovens /heat treatment furnace 33. In
fact, hot
exhaust flue travels 32 to out of the oven/heat treatment furnace. The exited
hot
exhaust flue will enters from 14 and it exits from 15 (refer to Fig. 15 &16).
This will heat
up the heat sink in thermal electrical generator device 31. In addition, a
single thermal
eclectic generator power device can be installed on the body of oven/heat
treatment
furnace as shown in Fig. 20, if the body is enough hot. To do so, heat sink of
the
thermal electric generator device should contact the body of the oven/heat
treatment
furnace 33.
For cooling down the thermal electrical generator devices 33 &31 we need to
use a
closed cooling system. It means water/coolant will travels between the thermal
electrical
generator devices 33 & 31 and cooling radiator 34. In fact, water/coolant will
be pumped
36 from the radiator 34 through pipe 37 to the thermal electrical generator
power
CA 3019290 2018-10-01
devices 33 & 31. And then the water/coolant goes back to the radiator 34
through pipe
35 to be cool down by the radiator. A fan can be used to cool down the
radiator 34 if it is
required.
