Definitions

  • the invention relates to heating equipment and is intended for space heating.
  • Known bimetallic radiator consisting of a steel pipe and aluminum fins / Patent for PO Sh 43245 from 02.16.97. Kl.23-03 /.
  • the disadvantage of this radiator is the great complexity of manufacturing, due to the fact that aluminum fins are obtained by pouring an aluminum alloy into a mold cavity around a steel pipe.
  • Another disadvantage is the low specific heat flux through a thick-walled steel pipe, which must withstand the pressure of the working fluid and whose thickness is 2.8 mm.
  • radiator consisting of a pipe and mounted on it longitudinal elements of the fins in the form of semi-cylindrical shells and rigidly connected with them longitudinal ribs / application _N93028354 MKP F24C 15/24 from 10.20.05. /
  • the disadvantage of this radiator is also a low specific heat flux through a thick-walled steel pipe, which must also withstand the pressure of the working fluid.
  • high precision manufacturing of the mating surfaces of the pipe and the inner cylindrical surface of the shell is required, which increases the complexity of its manufacture.
  • An object of the invention is to reduce the complexity of manufacturing, increasing the specific heat flux through the radiator.
  • the radiator consisting of the upper and lower collectors, the inner pipe and the fins, is equipped with a fins fastening device, consisting of at least two blocks interconnected by fasteners passing through the holes made in the fins.
  • FIG. 1 shows a general view of the radiator
  • FIG. 2 is a section A-A of FIG. 1
  • FIG. 3 is a section BB of FIG. 2.
  • the radiator consists of two collectors 1.
  • two bushings 2 inner pipe 3, fins 4, two blocks 5, fasteners in the form of bolts 6 and nuts 7.
  • This design of the radiator makes it possible to produce fins from sheet material, for example by stamping, which greatly simplifies the manufacturing process and reduces labor intensity, as well as to perform fins of complex shape and with a larger working surface, which leads to an increase in the specific heat flux through the radiator.
  • the pressure of the working fluid is completely transmitted through the walls of the inner pipe and through the fins to the pads - in the middle part along the height of the radiator, in the upper and lower parts - the pressure is transmitted from the inner pipe to the bushings.
  • the thickness of the inner pipe can be reduced from 2.8 mm to 0.5 mm or less.
  • a decrease in wall thickness leads to a decrease in thermal resistance and an increase in specific heat flux through the radiator. Due to the fact that the thin inner tube is constantly and with strong pressure pressed against the plastic aluminum fins, tight contact between them is achieved.
  • the device operates as follows.
  • the working fluid under pressure through the inlet of the manifold 1 enters the radiator. Further, moving along the inner pipe 3, it transfers heat to its walls. Due to the fact that the inner tube is pressed against the fins by the pressure of the working fluid, heat transfer from the walls of the inner tube to the fins occurs. Further, heat from the fins is transferred to the environment. Having passed through the inner pipe, the working fluid enters the manifold and exits the radiator through the outlet of the manifold.
  • the radiator is made as follows. Profiled sheets of fins 4 are obtained from stamping from sheet material, and holes are also made in the places where bolts 6 pass. On the inner tube 3 set sheets of fins.
  • pads 5 are installed on the assembled structure from two sides and tightened with bolts 6 and nuts 7. Then, from two sides: from the upper side and from the lower to the protruding ends of the inner pipe 3, put on the sleeve 2 and welding, connect the edges of the inner pipe with the sleeve, as well as the connection of the sleeve and pads. Then, a collector 1 is installed on each sleeve and the joint between them is scalded around the perimeter.
