Abstract

A conventional radiator arrangement comprises a radiator fan, which provides an airflow through a radiator mounted behind the radiator fan. Conventional radiators are substantially quadrangular. In the most cases, the airflow in the corners of the radiators is very low. Thereby, the heat transferring surfaces located in the corners of a conventional radiator do not provide an effective cooling of a coolant flowing in the radiator. The radiator arrangement, according to the invention, comprises a radiator fan, which provides a radial airflow outwardly and a radiator having an annular extension around the periphery of the radial radiator fan. The radial radiator fan provides here a substantially uniform airflow in all radial direction through the annular radiator. Thereby, the coolant obtains an effective cooling at substantially all heat transferring surfaces in the annular radiator. Consequently, such an annular radiator requires a smaller space than a conventional quadrangular radiator having the same cooling capacity.

A radiator arrangement for a vehicle

A conventional radiator arrangement for cooling of a motor in a vehicle comprises a radiator fan, which provides an axial airflow through a radiator mounted behind the radiator fan. However, an axial fan provides an airflow within an area having a substantially circular extension in a plane perpendicular to an axial flow direction. Since conventional radiators are substantially quadrangular, the airflow in the corners of the radiators is very low. Consequently, the heat transferring surfaces in the corners of a conventional radiator do not provide an effective cooling of a coolant, flowing in the radiator.

The object of the invention is to provide a radiator arrangement in which substantially all heat transferring surfaces of the radiator provide an effective cooling of the coolant flowing in the radiator. According to the invention, the radiator arrangement comprises a radiator fan, which provides a radial airflow and a radiator having an annular extension around the periphery of the radial radiator fan. The radial radiator fan provides a substantially uniform airflow in all radial direction through the annular radiator. Thereby, the coolant obtains an effective cooling at substantially all heat transferring surfaces of the annular radiator. Consequently, such an annular radiator requires a smaller space than a conventional quadrangular radiator having the same cooling capacity.
