  • the joining partners can be crimped or crimped together at the joint in the warm state in the height and / or width and / or depth direction 17, 15, 16 of the heat exchanger. Welding of the joining partners, for example by means of transmission laser welding, or gluing is also possible.
  • Plastics and processes for the production of, in particular, cross-flow heat exchangers are advantageous, for example silane-modified and crosslinked high-density polyethylene (HDPE) or polypropylene (PP) being advantageous.
  • low viscose matrix polymers are advantageous, such as liquid crystalline polymers (LCP), ETPE, HDPE / GF compound, PP / GF coumpound.
  • LCP liquid crystalline polymers
  • ETPE liquid crystalline polymers
  • HDPE / GF compound PP / GF coumpound
  • the HDPE or PP can be crosslinked by silane crosslinking technology. This allows the Continuous use temperature of the crosslinked polymer matrix can be increased to about 160 ° C.
  • the crosslinking of HDPE or PP leads to a significant improvement in the material properties and in particular the mechanical properties, which significantly extends the application possibilities of these cost-effective polyolefin materials.
  • the cross-linked materials are characterized by an increased impact strength, improved heat distortion resistance, increased chemical resistance and high fillability.
  • Silane cross-linking is most important for producing cross-linked polymer:
  • free radicals are formed by the thermal decomposition of organic peroxides. This process takes place during material preparation.
  • the hydrogen atoms of polyethylene macromolecules are abstracted by the radicals.
  • HDPE and PP generation are practiced in a two-stage process.
  • Suitable fillers are inorganic fillers, such as. SiC: BeO; BN; Al 2 O 3 ; ZnO; B 4 O 3 ; Glass; SiO 2 , BP, MgO, AlN, carbon black, etc.
  • Surface treatment of the inorganic filler particle and the glass fiber is carried out by means of the coupling reagents, e.g. For example, titanic acid or alkyl silane.
  • thermoplastics takes place in the development phase in the form of a two-stage process.
  • the grafting of the organosilane is carried out on the polymer, in the second step then the dynamic compounding of the thermoplastics and filler particles.
  • VTMOS condensable vinyltrimethoxysilane
  • VTEOS vinyltriethoxysilane
  • HDPE / PP 100phr Silane VTMOS or VTEOS: 0.5 ⁇ 6 phr; preferably 2.3- 3.0 phr DCUP * (DHBP **): 0.05 -0.5 phr; preferably 0.1-0.2 phr Master Bach: Thermostabilizer (Iganox 1010) 0.1 phr + DBTL (dibutyltin dilaurate (0.1-5 phr, preferably 0.2-0.3 phr) *: Dicumyl peroxide **: 2, 5-Dmethyl-2,5-di (tert-butylperoxy) hexane
  • the gel content of the silane-crosslinked polymer is between 60-85%, for higher operating conditions between 85-98%.
