Abstract

Cooler consists of a heat exchanger with diverging inlet for the hot fluid and means for cooling the hot fluid flowing through the passage. Specifically, the diverging inlet is tubular and at an angle of pref. 5 degrees. Specifically, the passage for the hot fluid flow is a centrally located tubular structure and the means for cooling the hot fluid flowing through it consists of a cooling chamber fitted around it.
