FR2511123A1 - Air heat exchanger for domestic fire-place - has horizontal and vertical air boxes with air guide vanes - Google Patents

Abstract

The heat exchanger consists of a hearth plate (1) with integral guide vanes (3) on the underside, a vertical backplate (2) with similar guide vanes at the back and a distribution discharge duct (6) directing warm air to the room. The hearth and backplate interlock at the corner (5) and form an air duct (4) through which the underflow fresh air flows. The vanes are orientated to direct air to the centre, which is the hottest zone. Fan assistance can be added and additional ductwork provided to serve adjacent rooms.

Description

DESCRIPTION.

- Air circulation heat flecuperator. The heat recovery unit places this in an old or new chimney. By circulating air in the device it passing through the fins heats and exits: through orifices placed on each side of the chimney and provides a gain of heat that is not in a chimney not equipped, this hot air can even be sent to other rooms using a blower, thus increasing the volume of heated air.

from the fireplace.

- The horizontal part Fiy 1 is placed on the hearth floor of the fireplace and is set 5cm in relation to it. It is necessary to create an air duct so that it arrives on the front of the appliance.

- The vertical part fig 2 this places above the orifice of the horizontal part and the hot air outlet element fig 3 above and diffuses the air on each side of the chimney. When a fire is made in the chimney, the cast iron heats up, the air which passes through the appliance is slowed down on the one hand by the horizontal fins (3) and brought back by the fins inclined at 450 (43 towards the center of the device where there is the greatest concentration of heat, this gives a higher efficiency, we can also increase this efficiency by passing more air with a blower.

I - the recirculating air heat recovery unit includes a
smooth floor plate I) and a decorated vertical plate t 2)
to which are connected fins E 3 3 and Ç 4 1 and with in
framing [5] all in one piece.

2 - this heat recovery unit is characterized in that the fins
are flat and dimension 5 X 5 cm and 1 cm thick and that they
are placed horizontally E 3) and other at 45% E 4) 3 - heat recovery unit is characterized in that it is made of cast iron
and in three elements including two heating elements C fig I) and
E Fig Z 3 and an air ducting element (fig 3) with hot air outlet 5 6)
This appliance can be manufactured in large quantities because it can be placed in an existing chimney as well as in a new one.
