A fan and a heat exchanger are provided in a housing. To achieve a compact construction and a greater air capacity, the fan is a radial-flow fan having a rectangular air outlet opening. The heat exchanger is disposed at one of the end faces of the fan, and the air inlet side of the heat exchanger is disposed at an angle to the axis of the fan. At least one air-guiding member is provided between the delivery conduit of the fan and the inlet side of the heat exchanger. The air-guiding member changes the flow of air emerging from the opening of the fan into an approximately right-angled or rectangular flow profile having a width corresponding to the width of the heat exchanger, with the flow striking the inlet side of the heat exchanger at an acute angle. | |
