Abstract

Invenţia se referă la un schimbător de căldură, care are ca fluide de lucru amestecul apă - antigel şi aer. Schimbătorul de căldură, conform invenţiei, este format din nişte tuburi dispuse într-o placă de bază, fiecare tub având o formă de picătură de apă, şi fiind prevăzut cu nişte aripioare plane. Tuburile au un capăt bombat şi un capăt ascuţit, unghiul de la capătul ascuţit fiind cuprins între 35 şi 60 grade, iar raportul dintre lungimile axelor este cuprins între 2,28 şi 1,36.
