Radiant module for a heating device for rooms, and method to produce said radiant module

Abstract

Radiant module and relative method of production, for a heating device for rooms, comprising two heat-conductor plates, respectively first and second, associated with each other to define a central portion inside which a heated heat-carrying fluid flows. The first heat-conductor plate comprises lateral walls which develop from the central portion away from the second heat-conductor plate, to define a channel inside the radiant module which develops and narrows from the lower part of the radiant module towards its upper part and through which a flow of heated air is accelerated and guided.

Description

FIELD OF THE INVENTION[0001]The present invention concerns a radiant module for a device, such as for example a mobile heat radiator, used to heat rooms. In particular, the radiant module comprises two heat-conductor plates associated with each other to define a central portion inside which a heated heat-carrying fluid is made to flow. The present invention also concerns a method to produce said radiant module.BACKGROUND OF THE INVENTION[0002]In the field of heating, heating devices are known, such as for example heat radiators, comprising one or more radiant modules, connected to each other and communicating hydraulically.[0003]Each radiant module comprises two metal plates, normally welded to each other in sealed manner, which define a central portion, more or less extensive with respect to the width of the plate.[0004]The central portions are normally connected hydraulically with each other by means of upper and lower collectors.[0005]A diathermic oil, heated by means of one or m...

AI Technical Summary

Benefits of technology

The present invention is a radiant module used in a device for heating rooms. It has two heat-conductor plates that are associated with each other to define a central portion where a heated fluid flows. The module has lateral walls that develop from the central portion and create a channel for the air to flow upwards and accelerate, resulting in a high-speed heat exchange with the ambient air and reducing the time for heating a room. The method for producing the module involves coupling the plates and shaping the first plate to create the channel. The invention also includes a heating device comprising multiple radiant modules.

Problems solved by technology

Known radiant modules therefore have the disadvantage that, due to extensive and unguided diffusion into the environment, the flow of heated air has a relatively low speed, with the consequence that the speed of heat exchange with the ambient air is reduced, which entails a low heating efficiency.

However, both these documents disclose channels that have a passage section substantially constant along their entire height, so no effect of increasing speed of the heated air can be obtained with these solutions.
