Combined equipment for heat-exchange Field of the art
The present industrial invention refers to the heat-exchange technology included in the International Classification F 24h.
State of the art
Heat exchange devices operating through heat radiation are well known, and heat-exchange devices operating under forced convection are known as well. In said forced convection equipment are employed exchangers with finned packs equipped with fans operated by electrical engines.
Recently, said equipment working under forced convection, originally conceived for winter heating, are employed also as air coolant in the summer season. In fact, by employing a cold fluid and dimensioning purposely the finned pack and the fan, a good cooling of the air during the summer season can be obtained.
Said cooling devices could be employed during the winter season also as heating fittings by making hot fluids circulate.
However, the operational noise of the fan represents a problem, especially at nighttime. Nevertheless, the fan can not be turned off because the finned pack, without convective ventilation, can not exchange enough heat to heat by working simply as a radiator.
The solution offered by the present invention allows to avoid the aforementioned problem and offers, with surprising simplicity, an optimal
comfort both during the summer season and the winter season.
Also, the present invention is affordable and can result into a item aesthetically suitable for any type of environment.
Furthermore, the operating of the invention can be programmed and modulated also for midseason weather, and represents a valuable aid for emergency situation during extreme heat or cold weather.
Description
The invention is now disclosed with reference to the schematic figures of the stylized drawings that are attached as a not limiting example.
Figure 1 represents schematically a combined heat-exchanger, in rest position, with the fan 3 turned off and without fluid circulation in the radiator 1 and in the convector 2.
Figure 2 represents the equipment in winter conditions with circulation of hot fluid in the pipe of the radiator 1 and with the fan 3 turned off.
Figure 3 represents the equipment in summer position with the circulation of cold fluid in the pipe of the convector 2 and with the fan 3 turned on.
Figure 4 represents the combined equipment in summer emergency position with the circulation of cold fluid in the pipes of both exchanger 1 and 2 and with the fan 3 turned on.
Figure 5 represents the combined equipment in winter emergency position with circulation of heating fluid in the pipes of both exchanger 1 and 2 with the fan 3 turned on.
Figure 6 represents the combined equipment in winter operational position with the circulation of heating fluid in the pipes of both exchanger 1 and 2 but with the fan 3 turned off, that is with the switch 4' open. In the figures each single detail is marked as follows:
1 indicates a heat-exchanger with radiant elements.
2 indicates a convection heat exchanger with finned pack.
3 indicates a fan next to the finned pack of the convection exchanger 2.
4 indicates the switch left open to turn off the electrical circuit of the fan 3. 4' indicates the closed switch to activate the electrical fan.
5 indicates the pipe for the circulation of the exchange fluid in the radiator 1.
7 indicates schematically the support structure of the combined heat-exchange equipment.
The clearness of the figures underlines the striking simplicity of realization and functioning of the combined heat-exchange equipment that constitutes the object of the present industrial invention.
It is clear that the functioning management can be controlled through radio devices especially programmed with instruments for the automatic control of the thermological parameters to grant the best indoor environmental conditions according to the changing weather conditions.
It is understood that the practical realization of the equipment object of the present invention can be performed with different forms of technical execution
which allow structural proportioning and dimensioning which can be adjusted to different technological and marketing needs.
It should be pointed out that the combined application of the heat-exchange equipment, whose operation entails the fan (3) operating noise and mild water condensation on the radiator (1) surface during hot weathers, would allow to endure emergency conditions in winter or summer times.
Upon disclosure of the main inventive characteristics of the present finding, any technician skilled in the art could realize by means of simple logical deductions and technical applications, without any inventive effort, equipment that can be derived by the present description and by the attached schematic drawings.
However, it is clear that such derived equipment will be considered part of the protection sphere of the present invention.
The inventive pivot of upon which the present invention is based and that constitutes the heuristic gradient characterizing the inventive step of the finding is the combination of the radiant element 1 with thermo-ventilator elements (2 e
3) with the goal of realizing a unified equipment which allows the summer cooling and the winter heating with thermal and acoustic comfort.
All kinds of equipment which will present the inventive characteristics as basically described, displayed and hereinafter claimed, will be considered as being part of the protection sphere of the present invention.
The core idea characterizing the present invention will be indicated in the following claim.
