Heat Exchanger Comprising a Tubular Element and a Heat Transfer Element

Abstract

The present invention relates to a heat exchanger (1) comprising a first flow passage (6) comprising a tubular element (2) comprising at least two tubular flow channels (4) separated by region (5) extending along a longitudinal Y-axis, for passage of a first medium, and a second flow passage (8) for passage of a second medium between tubular element and a heat transfer element (3). The tubular element comprises a first surface (A) comprising at least region and two bulging sections (7). The heat transfer element comprises a second surface (B) comprising at least region 5′ and two indentation, cavity or nest sections (17). The first surface and the second surface are adapted to contact each other and have a complementary shape such that the bulging sections of the first surface are in continuous contact with the indentation, cavity or nest sections of the second surface.

Description

FIELD OF THE INVENTION[0001]The present invention refers to a heat exchanger according to the characterized portion of claim 1 and a use of the heat exchanger in apparatus such as heating, ventilating, and air conditioning in buildings, heat radiators in engines, computers, heat absorbers and / or industrial coolers such as equipment for cooling transformers and power generators.BACKGROUND OF THE INVENTION AND RELATED ART[0002]Heat exchangers are utilized in a broad range of applications where it is necessary to transfer heat to or from a particular item or equipment, such as an air condition unit, booster or engine.[0003]A heat exchanger generally comprises an arrangement of channels forming a first flow passage and a first surface. A heat exchanger is further pro-vided with a plurality of heat transfer elements such as corrugated fins along and extending traverse to the length of the channels forming a second flow passage, whereby the fins provide a second surface. When the heat exc...
