Definitions

  • the invention relates to a method for producing heat exchangers from aluminum or alloy aluminum plates, mainly for use as a vehicle radiator.
  • the task of the various radiator systems is that they remove the superfluous heat from the surroundings of heat development (e.g. from the combustion chamber of engines), among other things, so that the thermal state of the components and the lubricants of the engine remain at a constant level, and thereby a temperature of the components exposed to thermal stress is achieved, which is equally optimal in terms of economy, energy and wear resistance.
  • the base material of the heat exchangers and the radiator of the vehicles was copper for a long time.
  • development has started in two directions: on the one hand, the aim is to increase the amount of heat falling on the unit volume of the radiator, for example by increasing the heat exchange area, on the other hand, in order to save energy and protect the environment, s reduce by using aluminum coolers of smaller weight. This is because aluminum is lighter and cheaper than copper, and at the same time it is lighter and has better thermal conductivity than steel.
  • the use of aluminum in the heat exchangers of the automotive industry has only begun in recent times, although in the aircraft after World War II some light metal structures satisfying the requirements for reducing the weight appeared.
  • the building up of the water pipes by water pressure has the disadvantage that the water must then be evaporated from the water pipes, and expensive auxiliary tools must be used for the water pipes with different cross sections.
  • the production of the water pipes made from a band by interlocking is very labor-intensive, and the second method mentioned is also no less complicated.
  • the radiator surface-increasing fins are attached to the water pipes produced in this way with mechanical connection or by soldering.
  • the object of the invention is to elaborate a method which substantially simplifies and accelerates the production of heat exchangers from aluminum or alloyed aluminum plates, and thereby enables productive and cheap mass production.
  • the invention is based on the knowledge that the individual elements of the heat exchanger can also be made from two coincident parts if the connection of the two parts can be carried out by a cheap and fast method.
  • the latter is mainly granted through the knowledge of the possibility of aluminum soldering, as well as through the appearance of new adhesives.
  • the object is achieved according to the invention in that the lower and upper liquid collector serving as the base material of the heat exchanger and the aluminum or alloy aluminum plate, as well as at least one connecting cavity forming this connecting tube, are pressed, two pressed pieces configured in this way with their hollow sides facing each other with an inseparable connection are connected to a heat exchanger member, and the individual heat exchanger members are also fastened to one another along the side surface of their liquid collector with an inseparable connection.
  • the press pieces forming the individual heat exchanger members are expediently soldered to one another, but the connection of the press pieces can may also be carried out by gluing.
  • the surfaces of the connecting pipes during the pressing are formed with ribbing which increases the surface area.
  • two uniform pressing pieces are juxtaposed with their hollow sides, but are fastened to one another in a position rotated by 180 ° relative to one another.
  • This solution is e.g. used when the surface of the pipeline describes a wavy line.
  • the heat exchanger members described above are glued together according to the invention. Such a solution is also conceivable that the connection of the heat exchanger elements is carried out using a solder with a melting point different from the solder used for connecting press pieces.
  • FIG. 1 shows a side view of the pressing piece which forms one half of the heat exchanger element produced according to the invention
  • FIG. 2 shows a section of the upper part of a heat exchanger according to the invention consisting of three interconnected heat exchangers
  • Fig. 3 is a top view of the construction shown in Fig. 2.
  • the upper and lower liquid collectors 1 and 2 form a coherent cavity with the connecting pipe 3 connecting these parts, which in one work process can be made into an aluminum or alloyed aluminum plate or into one Aluminum strip is pressed.
  • Lamellae 4 are formed from the non-pressed edges of the plate.
  • the press piece designed in this way is soldered along the surface of the fins 4 to another press piece of a similar design, and expediently so that the two press pieces are connected with their hollow sides opposite one another in a position rotated by 180 ° relative to one another.
  • heat exchanger elements 5 with an increased cooling surface are produced, the corrugated connecting tubes 3 and on the upper and lower part each have their own liquid collector, as can be seen from FIG. 2.
  • the connecting pipes 3 can also be straight.
  • the lined up heat exchanger elements 5 according to the type described above give the full scope of the heat exchanger.
  • the individual heat exchanger elements 5 are connected to one another along the side surface 6 of the liquid collector 1, 2, expediently by gluing, possibly by soldering.
  • the lower and upper liquid collector spaces of the individual heat exchanger elements 5 are provided with openings on their two side surfaces 6, as a result of which the cooling liquid 7 can flow through the heat exchanger elements 5.
  • Fig. 3 the direction of flow of the air flowing through the heat exchanger members is designated by the reference number 8.
  • Sockets can expediently be attached to the side surface of the heat exchanger elements by gluing or possibly by soldering.
  • the heat exchangers designed in this way can already be combined with the known frame so that they can be attached to the corresponding part of a car as a cooler.
  • the heat exchangers produced according to the invention can also be used for oil coolers for electrical transformers, freezers for refrigerators, calorifers, etc.
