Embodiment Construction

[0028] figure 1 Shown is a cooling module 10, in particular for a vehicle air conditioning unit of a truck, with a fan 12 and a condenser 20, the fan having an air inlet 14 and an air outlet 16 and creating an air flow direction from the air inlet 14 to the air outlet 16 Air flow at 18, which can pass through said condenser bidirectionally, i.e. in two opposite air flow directions, for liquefaction of refrigerant for a vehicle air conditioning unit, said condenser having an air flow cross-section A 1 And arranged adjacent to the air outlet 16 downstream of the fan 12 . In this respect, it is expressly pointed out that terms such as “downstream” and “upstream” in the context of the present application always refer to the air flow direction 18 .

[0029] In this exemplary embodiment, the fan 12 comprises two axial fans and is driven by an electric motor, wherein the fan 12 provides a maximum static pressure difference of at most 300 Pa.

Abstract

The invention relates to a cooling module (10), in particular for a vehicle air conditioning system for trucks, having a fan (12) and a condenser (20), the fan having an air inlet (14) and an air outlet (16) and generating from Air flow in the air flow direction (18) from the air inlet (14) to the air outlet (16), the condenser can flow bidirectionally through the refrigerant used to liquefy the vehicle air conditioning system, the condenser (20) has an air Flow cross section (A 1 ) and is arranged so as to be adjacent to the air outlet (16) of the fan (12), with the air flow cross section (A 1 ) has a first partial cross-section (22) and a second partial cross-section (24) different from the first partial cross-section (22), wherein the air outlet (16) of the fan (12) is assigned exclusively to the first partial cross-section (22) and loading the first partial cross-section with the entire air flow of said fan (12) in the air flow direction (18), and wherein the second partial cross-section (24) can selectively move in the fan during operation of the fan (12) The air flow direction (18) of the fan (12) flows in and opposite to the air flow direction (18) of the fan (12). Furthermore, the invention relates to an assembly (28) for cooling a motor vehicle engine (30) with a cooling module (10) of this type.

Description

technical field [0001] The invention relates to a cooling module of a vehicle air-conditioning unit, in particular for a vehicle air-conditioning unit of a truck, having a fan which has an air inlet and an air outlet and generates a flow from the air inlet to the air outlet in the direction of air flow The air stream, and the condenser through which the air stream passes, are used to liquefy the refrigerant for the vehicle air conditioning unit. Furthermore, the invention also includes an assembly for cooling a motor vehicle engine, in particular a truck engine, which has a radiator fan, which has a fan inlet and a fan outlet and which can generate a flow from the fan in the direction of air flow. Inlet to ventilator outlet air retention; engine radiator through which air flows for cooling the coolant of a motor vehicle engine, said engine radiator having an airflow cross-section and arranged adjacent to a ventilator inlet of said radiator ventilator , and the condenser throu...
