Definitions

  • the invention relates to a tube heating body consisting of two single-walled supporting tubes with a smooth surface, fitted with a system of crosswise situated interconnecting holes in the wall of the supporting tubes, to which are by their ends the single-walled interconnecting tubes with a smooth surface crosswise assigned, while the interiors of the supporting tubes and the interconnecting tubes are interconnected.
  • a tube heating body is a heating body consisting of two supporting tubes with a smooth surface, i.e. a surface without ribs, while the supporting tubes are along their length in the walls fitted with a system of crosswise situated interconnecting holes, to which are the interconnecting tubes with a smooth surface, i.e. a surface without ribs, assigned crosswise to the supporting tubes.
  • the interior of the supporting tubes is interconnected by hollows in the interconnecting tubes, thus the circulation of a heating medium is made possible.
  • the interconnecting and the supporting tubes are mutually positioned perpendicularly.
  • welded or soldered tube heating bodies which are produced in the manner that a line of holes is made in the supporting tubes, which in their turn are of any shape and size of the cross section, where the holes can have an inward turned flange to improve the bearing power of the future joint with the interconnecting tubes.
  • a system of interconnecting tubes prepared with convenient shape and size of their cross section with respect to the supporting tubes while each of the interconnecting tubes can be on both ends for example conical frustum shaped. Consequently each of the interconnecting or the supporting tube is welded or soldered separately or the both ends of the interconnecting tubes are inserted into the above mentioned holes in the supporting tubes, while a structure of the tube heating body is formed, which is secured e.g. by using spot welding or welding fixture to hold the entire built-up body together. Consequently there is welding or soldering of particular joints of the supporting or the interconnecting tubes of this built-up tube heating body carried out.
  • a common disadvantage of the known tube heating bodies and methods of their production consists in that the manual welding or soldering induces low manufacturing productivity.
  • a machine welding or soldering either sequential for each joint or mass for all joints of one body at once, there is a higher to high manufacturing productivity that is hard paid by the necessity to use expensive and relatively complex welding or soldering machinery demanding higher operating and repairing costs increasing the manufacturing costs.
  • Another disadvantage of the background art consists in that there is not a way without specialized and sophisticated technological devices to weld or solder any material combinations, while in consideration of connecting mutually crosswise oriented tubes it is also difficult on a relatively small contact surface or even only in a contact line to guarantee the desired quality of the joint, which in its turn has to meet required bearing power and particularly high impermeability and repeated heating and cooling resistance associated with repeated expansion and contraction of heating body parts.
  • a fin heating body for a hot water distance heating system with upper supply of a heat transfer fluid into a system of heating elements made of aluminium or aluminium base alloys.
  • the body consists of two parallel carrying bodies in which there are connecting tubes constructed, between which heating elements made of extruded section are arranged.
  • the elements consist of a heat transferring tube, which is from the front side fitted with a cross rib with a front longitudinal plate, while the heat transferring tube is from the back side fitted with a back plate.
  • the heating body fitted with a pair of supporting ribs.
  • the supporting bodies In the axis of the heat transferring tube, there are connecting holes made in the supporting bodies leading into the connecting tubes, which are interconnected with the ends of the heat transferring tubes using the interconnecting tubes fixed by anaerobic bonds based bonded joints in the connecting holes and in the heat transferring tubes.
  • the supporting bodies are on the front side fitted with heat transfer plates.
  • the supporting bodies are further fitted with bearing grooves, by which they are fixed on the supporting ribs of the heating elements.
  • the back plate of the heating element is divided along longitudinal plane of symmetry of the heat transferring tube in two halves between which there is a hanging groove formed.
  • the disadvantage of this arrangement consists in considerable shape complexity of particular parts of the heating body, which requires use of sophisticated manufacturing technologies of particular parts of the heating body.
  • Another disadvantage of this arrangement is the necessity of connection of particular parts of the heating body using only a long interconnecting tube, by which a large contact surface of connected components and expected bearing power and impermeability of the bonded joint is reached. This imposes higher demands on manufacturing of points of connection and on overall construction of the entire body.
  • Last but not least disadvantage of this body is that it can be used for more purposes only in a very limited configuration, such as, except for heating, for e.g. in textile drying in households, which is in principle limiting the use of this solution in households.
  • the invention intends to propose such tube heating body made from mutually perpendicularly arranged tubes with a smooth surface, which would lead to decrease of manufacturing costs and increase of manufacturing productivity ensuring high variability of uses.
  • a tube heating body consisting of two single-walled supporting tubes with a smooth surface, fitted with a system of crosswise situated interconnecting holes in the wall of the supporting tubes, to which are by their ends the single-walled interconnecting tubes with a smooth surface crosswise assigned, while the interiors of the supporting tubes and the interconnecting tubes are interconnected, whose principle consists in that the supporting tubes and the interconnecting tubes are connected by bonded joints, which makes the manufacturing easier and the manufacturing costs decrease.
  • the interconnecting holes are smooth and the ends of the interconnecting tubes are of a shape of a conical frustum, where its larger base is of a larger diameter than the diameter of the interconnecting holes and the smaller base is of a smaller diameter than the diameter of the interconnecting holes and the interconnecting tubes are by their ends inserted in the interconnecting holes in the supporting tubes, where the ends of the interconnecting tubes are bonded with the supporting tubes.
  • This embodiment is easy and reliable.
  • the interconnecting holes are fitted with built-in recess with an inner wall and the ends of the interconnecting tubes and the inner walls of the built-in recess of the interconnecting holes are mutually adjusted in the view of shape and size, while the ends of the interconnecting tubes are inserted in the interconnecting holes, where they are bonded together with the inner walls of the built-in recess of the interconnecting holes.
  • This embodiment makes possible the use of lower grade bonds, because a larger contact surface of bonded components leads to an improved bearing power and durability of bonded joints.
  • interconnecting adapters which makes possible to form several transition effects between the supporting and the interconnecting tubes and also enables, as the case may be, to eliminate possible difficulty to connect the supporting and the interconnecting tubes directly by bonding, because it is possible for this purpose to use such interconnecting adapter material, which can be easily connected by bonding to the both supporting and interconnecting tubes.
  • the interconnecting adapters are by bonded joints fixed at the ends of the interconnecting tubes and also at the same time on the supporting tubes and if they comprise a hollow interconnecting interior of the interconnecting tubes through the interconnecting holes in the supporting tubes with the interior of the supporting tubes.
  • interconnecting adapters are on the supporting tubes fixed by bonded joints.
  • the interconnecting adapters are on their side adjacent to the supporting tubes fitted with a bearing surface shaped as a reverse to the opposite wall of the supporting tube, which is an easy and reliable solution.
  • the interconnecting adapters are on their side adjacent to the supporting tubes fitted with a protrusion, by which they are situated in the interconnecting holes in the supporting tubes.
  • the advantage of the solution according to the invention consists in that it is possible to use the bonding technology with all positive effects in such specific heating body as the tube heating body is, where it is not possible by engineering practice to reach the required or expected size of the contact surface of the connected components, because through the crosswise holes in the supporting tubes there are connected components that are mutually perpendicular and moreover, these components are thin-walled. Considering the diameters it is not possible even by inward built-in recess in the crosswise holes in the supporting tubes to reach by engineering practice in the field of bonding the required or expected size of the contact surface of the connected components. One can reach only a slight enlargement of the connected surface by the means of recess.
  • connecting adapters does not enable to reach by engineering practice in the field of bonding the required or expected size of the contact surface of the connected components, because aesthetic considerations play a role, which with respect to appearance demands do not allow to use the connecting adapters for enlargement of connected surfaces to the size required or expected by engineering practice in the field of bonding. Also with regard to flow capacity of a heating medium through the heating body there cannot be used the devices interfering deep into the hollow of the supporting tubes.
  • the stress on the bonded joints of the tube heating body is specific when owing to the changes in temperature of the heating body comes to thermal dilatations, when as a consequence of arrangement of the tube heating body while its irregular continuous heating, the crosswise holes in the supporting tubes diminish while the interconnecting tubes and eventual connecting adapters expand.
