HEAT-EXCHANGER

摘要

The invention concerns a heat-enchanger comprising at least one cross-flow heat-exchanger module (M) having two alternately attached sets of plates (1a, 1b). Each plate (1a, 1b) has internal channels (5a, 5b) for gas circulation which extend longidutinally, parallel and unidirectionally inside the plate (1a, 1b). The channels (5a, 5b) in one set of plates (1a, 1b) are aligned in the same direction and at a predetermined angle to the direction of alignment of the channels (5a, 5b) in the other set of plates (1a, 1b). According to the invention, a certain number of plates (1a, 1b) of said module have at least one opening (E), obtained in particular by cutting, which facilitates heat exchange between the gas streams. The invention is useful in ventilation or air-conditioning installations in enclosed spaces such as offices, cinemas, theatres, conference rooms, indoor stadia, private homes, apartment blocks, factories, etc.
