Description
The invention relates to a heat exchanger intended for
a central heating boiler, which heat exchanger is designed as
a monocasting from substantially aluminum, the heat exchanger
comprising a number of walls which bound on one side a water-carrying
channel and on the other a burner space.
A central heating boiler comprising such heat exchanger
is known from practice and is for instance marketed by
applicant under the type indications W21c ECO and W28c ECO.
The maximal output of the known boiler is 21 kW and 28 kW
respectively. A particular advantage of the known boiler is
that it is particularly compact. The built-in depth of the
known boiler is for instance 350 mm. Another advantage of the
heat exchanger of the known boiler is that it is designed as
a monoblock casting, as a result of which the manufacture
thereof is relatively simple.
The output of a central heating boiler is inter alia
determined by the size of the burner that is used. In the
known boiler, the burner, which is substantially of
cylindrical design, is cantilevered at one end face thereof.
When a greater output is required, the length of the burner
could be increased. However, this leads to problems with
regard to the one-sided suspension of the burner. Moreover,
as a consequence hereof, the built-in depth of the central
heating boiler becomes too great.
Another possibility for increasing the output of the
known boiler is enlarging the diameter of the burner.
Although this is in itself possible, the amount of flue gas
to be discharged will then form a problem. The known boiler
comprises a single flue gas draft. In this single flue gas
draft the temperature of the flue gases must be reduced as
far as possible, so that as much heat as possible is
transferred from the flue gases to the water to be heated. In
order to arrive at a proper heat transfer, pins increasing
the heat-transferring surface extend in the flue gas draft.
To enable the larger amount of flue gas to be discharged, the
section of the flue gas draft would have to be enlarged. This
means that for a proper heat transfer to be maintained, the
pins increasing the heat-transferring surface would have to
be of a longer design. However, this is not possible, because
during the casting of the heat exchanger, the molten aluminum
flowing into the cavities for forming the pins has already
solidified before the end of the cavity is reached.
Consequently, the further elongation of the pins is not
possible due to problems in terms of casting technique. Due
to the above-described problems, it is not possible to merely
increase the diameter of the burner for increasing the output
of the central heating boiler.
The object of the invention is to provide a heat
exchanger intended for a central heating boiler having a
greater output than the known central heating boiler, the
intended heat exchanger being particularly compact and hence
suitable for a central heating boiler which, like the known
boiler, has a slight built-in depth.
To this end, the heat exchanger according to the
invention is designed as a monocasting from substantially
aluminum, the heat exchanger comprising a number of walls,
which walls bound on one side a water-carrying channel and on
the other a burner space and at least two parallel flue gas
drafts, which flue gas drafts extend from the burner space,
the burner space being intended for accommodating a burner,
the walls which bound the burner space and the flue gas
drafts being water-cooled in that the water-carrying channel
extends therealong, the water-carrying channel being of such
design that it can be formed with a single, one-piece core.
The heat exchanger being designed as a monocasting, it
can be manufactured in a relatively quick and efficient
manner. The presence of more than one flue gas draft enables
discharging a greater amount of flue gas, while the section
of the flue gas drafts can remain small, so that relative to
the flow-through section, a relatively large heat-transferring
surface is nevertheless obtained. Due to the
greater amount of flue gas that can be discharged, a larger
burner having a greater output can be used. Outputs up to
about 30 kW per flue gas draft are possible in the heat
exchanger according to the invention. Because the heat
exchanger according to the invention now involves parallel
flue gas drafts, preferably located side by side, the slight
built-in depth of the known central heating boiler can be
maintained. Hence, with the heat exchanger according to the
invention, a central heating boiler can be provided having a
greater output than the known central heating boiler while
the same degree of compactness is achieved, in particular
with regard to the built-in depth. As the walls which bound
the burner space and the flue gas drafts are water-cooled, an
optimal heat-transfer to the water to be heated is obtained,
while, moreover, the heat exchanger is cooled in an efficient
manner, so that it nowhere becomes overheated. The one-piece
core renders the manufacture of the core and the positioning
of the core in the mold relatively simple, so that the
manufacture of the heat exchanger is relatively simple as
well and, accordingly, can take place in an economically
favorable manner.
According to a further elaboration of the invention,
intended for increasing the efficiency of a central heating
boiler, comprising a heat exchanger according to the
invention, each flue gas draft of the heat exchanger may
comprise two opposite walls having pins extending
substantially perpendicularly thereto, which pins enlarge the
heat-transferring surface and extend into the relevant flue
gas draft.
The invention also relates to a central heating boiler
comprising a heat exchanger according to the invention. It is
a matter of course that such central heating boiler has the
advantages mentioned hereinabove in respect of the heat
exchanger.
Further elaborations of the invention are described in
the subclaims and will hereinafter be specified on the basis
of an exemplary embodiment, with reference to the
accompanying drawings.
Fig. 1 shows an exemplary embodiment of the heat
exchanger 1 according to the invention. As is clearly
visible, the heat exchanger 1 is designed as a monocasting
substantially from aluminum. The heat exchanger comprises a
number of walls 2, 3, 4, which walls bound on one side a
water-carrying channel 5 and on the other a burner space 6
and two parallel flue gas drafts 7, 8. The flue gas drafts 7,
8 extend from the burner space 6. The burner space 6 is
intended for accommodating a burner. The walls 2, 3, 4
bounding the burner space 6 and the flue gas drafts 7, 8 are
water-cooled in that the water-carrying channel 5 extends
therealong. The water-carrying channel 5 is of such design
that it can be formed with a single, one-piece core 9, shown
in Fig. 3. Each flue gas draft 7, 8 comprises two opposite
walls 2, 3 having pins 10 extending substantially
perpendicularly thereto, which pins enlarge the heat-exchanging
surface and extend into the relevant flue gas
draft 7, 8. The flow system of the water-carrying channel can
be considered to be a series connection of a number of
parallel channel parts. In explanation thereof, I refer to
Fig. 3, which, it is true, shows the core by means of which
the water-carrying channel is formed, but which can also be
considered to be a representation of the water-carrying
channel itself. Water coming from a central heating pipe
system enters the heat exchanger adjacent its bottom side at
the location of arrow R. From there, it continues its path in
a feed-in part 5a of the water-carrying channel 5. Adjacent
the rear of the heat exchanger 1, the channel 5a divides into
two separate channel parts 5b, 5c. Such division is clearly
shown in Fig. 2. Located in channel 5b is a partition 11
which forces the hot water to flow forwards again to
subsequently rise again and flow back towards the rear again.
From the rear, the water then flows in a common channel part
5d which separates the two flue gas drafts 7, 8 from each
other. In the channel 5d, too, a partition 12 is located,
which provides that the water first flows forwards and then
upwards, to subsequently flow to the rear again, enabling the
water to divide again from there and flow to two following
separate subchannels 5b' and 5c'. This process repeats itself
again, after which the water flows, via 5b''' and 5c''', into
a common channel 5E, whence the water flows to the inlet A of
the central heating pipe system. With such embodiment of the
water-carrying channel 5, it is effected that all walls of
the flue gas drafts and the burner space are water-cooled, so
that an optimal efficiency is obtained and all parts of the
heat exchanger remain sufficiently cooled. To effect an easy
cleaning of the flue gas drafts and a proper accessibility of
the burner space 6, this burner space 6 and the flue gas
drafts 7, 8 are accessible from at least one side S. The side
S is clearly indicated in Fig. 2. Fig. 2 also clearly shows
that the water-carrying channel 5 has a substantially m-shaped
section, viewed in a direction perpendicular to a
horizontal cross-sectional plane II-II located at the level
of the flue gas drafts 7, 8.
It is readily understood that the invention is not
limited to the exemplary embodiment described, but that
various modifications are possible within the framework of
the invention. For instance, the heat exchanger may comprise
three or more flue gas drafts, and instead of a cylindrical
burner room 6, a burner space having a different shape may be
used.
