Abstract

A fan housing for a vehicle system includes a housing frame extending in a peripheral direction and penetrated by a connection opening for suctioning external air or external particles. A suctioned airflow or particle flow flows through the housing frame as a suction flow and in a direction of flow. Starting from the connection opening, a connection pipe extends in a direction outside the housing frame and a partition extends in a direction inside the housing frame.

First claim

The invention claimed is:

1. A cooling circuit for cooling an engine of a vehicle system, comprising:
a heat exchanger;
a connection pipe;
a fan housing including a housing frame defining a connection opening at a periphery in an upper region of the housing frame, the connection opening coupled to the connection pipe;
a fan disposed downstream of the connection opening and the heat exchanger, the connection opening disposed between the heat exchanger and the fan;
a first airflow of particles suctioned through the connection pipe and into the fan housing via the connection opening disposed at a first incline in a rear direction;
a second airflow of particles configured to flow through the heat exchanger and into the fan housing; and
a partition extending into the fan housing downstream of the first and second airflows, the partition separating the first and second airflows from one another at the periphery in the upper region of the housing frame, the partition including a substantially vertical free end disposed within the periphery in the upper region of the housing frame, the free end being sharp-edged;
wherein the connection pipe extends externally from the housing frame starting from the connection opening at the first incline opposite the first and second airflows and at a second incline in a peripheral direction.

2. A fan housing for a vehicle system, comprising:
a housing frame defining a connection opening at a periphery in an upper region of the housing frame for receiving suctioned particles;
a connection pipe fluidly coupled to the connection opening for suctioning particles therethrough, the connection opening disposed at a first incline in a rear direction;
a first airflow of particles suctioned through the connection pipe and into the housing frame via the connection opening, the first airflow flowing in a first flow direction;
a second airflow of particles configured to flow into the housing frame, the second airflow flowing in a second flow direction; and
a partition extending into the fan housing downstream of the first and second airflows, the partition separating the first and second airflows from one another at the periphery in the upper region of the housing frame, the partition including a substantially vertical free end disposed within the periphery in the upper region of the housing frame, the free end being sharp-edged;
wherein the connection pipe extends externally from the housing frame starting from the connection opening at the first incline opposite the first and second airflows and at a second incline in a peripheral direction.
