Collective heating unit, especially for electric heater

Abstract

 The invention solves the question of heating unit and is characterized by having a planar barrier 6 placed above the heating body 1, with planar barriers 6 being alternatively shorter than or sectional in relation to the heating body 1.

Description

[0001] The subject of invention is the collective heating unit, especially for electric heater.

[0002] Known is the heating unit from the description of invention No. WO95/02952, where the electric heating system has a resistance heating body in form of a massive body e/g a tube or plate. The body, made of semi-conducting material, is the carrying part for the heated object or it leads the said heated object. Resulting from this are vast contact surfaces to transmit the heat and high efficiency.

[0003] The matter of the invention is, that the collective heating unit composed of individual heating units with proper heating bodies is characterized by every single heating unit having planar barrier separated from heating body by free space, and single heating units are placed above each other.

[0004] The heating body is longitudinal heating lead with thermo-insulating material.

[0005] The planar barrier is longitudinal.

[0006] The planar barrier is shorter than the associated heating body.

[0007] The planar barrier is longer than the associated heating body.

[0008] The planar barrier is sectional related to longitudinal heating body.

[0009] The materials insulating the heating lead are based on the mica.

[0010] The planar barrier is in form of an angled section placed at the heating body.

[0011] According to the invention, the collective heating unit allows for the barrier-defined flow of the air, heated in the free space, thus making decidedly higher the efficiency of heating plants.

[0012] The subject of the invention has been visualized in the example shown on the drawing, where fig. 1 shows en face the single heating unit, fastened to the panel wall, fig. 2 shows the cross section of the single heating unit under fig. 1, fig. 3 shows perspective view of the heating lead with thermo-insulating screen, fig. 4 shows the joint of thermo-insulating plates along with heating lead, fig. 5 shows perspective view of the collective heating unit with various single heating units placed on the wall of an electric heater below each other.

[0013] According to the invention, the collective heating unit is composed of single heating units, each of which itself has the proper heating body 1, being e/g a spiral heating lead 2, sheltered by thermo-insulating material 3. The thermo-insulating material 3 are four mica thermo-insulating plates 4. The thermo-insulating plates 4 are fastened with each other by joints 5.

[0014] The heating unit has a planar barrier 6, separated from the heating body 1 by free air space 7.

[0015] Advantageous is placing of angled section being the planar barrier 6 parallel to the heating body 1.

[0016] Planar barriers 6 may be sectional to the heating body 1, with additional free air spaces 8 emerging between barriers 6.

[0017] According to the invention, the single heating units may be fastened above each other, alternatively with use of the sectional planar barrier 6 and the barrier 6 shorter than the heating body 1. The single heating units fastened such way constitute the collective heating unit for the electric heater with high heating efficiency.
