Abstract

The invention solves the problem of heat exchanger bundle design, made of extruded profiles (1) with maintaining the outer circumference (V) to height (H) ratio in the range from 2.5 to 12, that means V/H = 2.5 ÷ 12, and maintaining the cross section area sum (F) to outer circumference (V) ratio in the range from 1 to 5, that means F/V = 1 ÷ 5, giving the form of flow slots (2) characterized by width (s) to height (h) ratio in the range from 0.005 to 0.1, that means s/h = 0.005 ÷0.1.

Description

  • The object of the present invention is a fired heat exchanger bundle, the most beneficial used in the hot water boilers or in flow heaters.
  • In the state of the art of engineering, were known different heat exchanger constructions. And for example, Buderus company utilize for heat exchanger closed stamped aluminium profiles, also aluminium tubes with outside ribs and helical channel inside and also utilizes the helically coiled thin wall aluminium tubes. The Viessmann company utilizes the heat exchangers made of corrugated stamped steel plates or heat exchangers cast from aluminium, with outer surface formed into cylindrical protrusions. Viessman and Giannoni companies manufacture heat exchangers with helical, flatten thin wall steel tubes.
  • The weak point of such solutions is complicated, multipart construction impeding assembly automation and as well significantly reducing reliability of the unit, which in turn cause high manufacturing and assembling costs and also utilization costs.
  • The aim of the solution according to the present invention is development of new heat exchanger bundle with elimination of weak points of known solutions of heat exchangers.
  • In the solution according to the present invention, fired heat exchanger bundle is made of extruded profiles with maintaining of the outer circumference ( V ) to height ( H ) ratio in the range from 2.5 to 12, that means V/H = 2.5 ÷12 and the cross section area sum ( F ) to outer circumference ratio ( V ) in the range from 1 to 5, that means F/V = 1 ÷ 5, receiving the flow slots ( 2 ) configuration with width ( s ) to height ( h ) ratio in the range from 0.005 to 0.1, that means s/h = 0.005 ÷0.1.
  • The solution of the fired heat exchange bundle according to the present invention eliminate the weak points of know solutions, reducing to the minimum number of heat exchanger elements and providing the higher operating reliability. Also were obtained significant material and technological simplification of bundle execution, which has significant influence on product manufacturing cost.
  • The vital advantage of the solution is construction scalability, giving the possibility of elastic adaptation to required parameters of chosen unit.
  • The subject of the present invention is presented on an execution example, on the enclosed figures on which fig. 1 presents the perspective view from heat exchanger bundle head, fig.2 presents the detail "A" of the heat exchanger bundle like on the fig.1, fig.3 presents the head view of one segment of heat exchanger bundle.
  • The fired heat exchanger bundle according to the present invention is made of extruded profiles 1 , in which are formed flow slots 2 and passage channels 3 . Extruded profiles maintains the outer circumference V to height H ratio in the range from 2.5 to 12, that means V/H = 2.5÷12 and maintains the cross section area sum F to outer circumference V ratio in the range from 1 to 5, that means F/V = 1 ÷ 5. Maintaining of such dimensional ratios allows formation of flow slots 2 characterized by width s to height h ratio in the range from 0.005 to 0.1, that means s/h = 0.005 ÷0.1.
