Abstract

The solution falls within the household, space or air conditioning heating system and relates to flexible lamellas for heat transfer, consisting of two longer walls connected by one shorter wall (7), characterized in that on the shorter wall (7) are formed radius surfaces (1) identical to the diameter of the pipes (2) of the register and on the free ends of the two longer walls (5j are formed both negative radius surfaces (3) and positive radius surfaces (4) for mutual support after being slid onto the pipes (2) of the register and closing the profile thus formed. The front and rear walls of the flexible lamella are provided with horizontal recesses (6) on the front wall for the cold air inlet and on the rear wall for the heated air outlet. Another possibility of flexible connection by prestressing between the pipes (2) of the register is a flexible lamella formed as a whole with a break (9) in one place.

Description

The present invention relates to flexible lamellas for heat transfer. The flexible lamellas can be used for a flexible connection with the thermocirculation profile, thus allowing the transfer of heat into the space, for example, in radiators for heating buildings or in refrigeration.

Known embodiments of the heat transfer elements between the thermocirculating profile and the jacket or slats are made as clips, sleeves, stabbing clips, tensioning and pressure springs. These structural elements increase the thermal bridge when the thermocirculation profiles come into contact with the heat transfer surfaces and the heat transfer is not sufficient and there is a considerable loss in the use of thermal energy.

The above-mentioned disadvantages largely eliminate the flexible lamellas according to the invention, the essence of which is that the lamellas are flexibly pushed into the thermocirculation profile under prestressing. The flexible lamellas for heat transfer consist of two longer walls with horizontal embossments connected by one shorter wall. Radius surfaces equal to the diameter of the register tubes are created on the shorter wall and negative radius surfaces and positive radius surfaces are created at the free ends of the two longer walls. These flats close the profile formed in this way when supported against each other after insertion into the register tube.

By the elastic connection of the heat-exchanging surfaces of the flexible lamellas to the thermocirculating profile which is inside the radiator, an increased heat transfer from the thermocirculating profile to the heat-exchanging surfaces - the flexible lamellas is achieved by means of which radiation and convection of warm air into the space. The hot water radiators formed by the flexible lamellas of the present invention exhibit an increased heat output over the known types of radiators with reduced weight. This progress and the higher effect which results in increased heat output must be seen in the fact that the flexible lamellas ensure constant contact with the thermocirculation profile filled with the heat transfer substance.

BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in more detail in the accompanying drawings, in which Fig. 1 shows a flexible lamella before insertion between register tubes. Giant. 2 shows the flexible lamella already inserted between the register tubes. Giant. 3 illustrates horizontal embossments. Giant. 4 shows the direction of air flow in the recesses. Giant. 5 shows the flexible lamella as a whole with one break. Giant. 6 shows horizontal embossments. Giant. 7 illustrates the direction of air flow in the indentations.

The flexible lamellas are made up of a shorter wall 7 on which radial surfaces 1 equal to the diameter of the register tubes 2 are formed. On the other shorter wall 8 of the lamella, two elastic radius surfaces 3 are formed in one lamella and two elastic surfaces 4 positive are made in the other lamella. On the longer walls 5, horizontal embossments 6 are made which serve on the front wall for the entry of cold air and the rear embossments for the exit of the heated air. The second variant of the flexible lamella is formed as a whole with the break 9 in one place. The break has no end thrust pads. When pulling to the required preload, the boom parts of the flexible plate overlap. The flexible lamellae are slid between the tubes 2 and then together with the tubes 2 contracted to the desired bias before welding with the inlet and outlet tubes 2.

For technology without welding, it is possible to assemble the tube register from tubes screwed into 90 ° branches and insert the lamellas between the tubes and shrink them to the required preload using radiator nipples similar to the removal of steel or cast iron elements.
