Description

The invention relates to vehicles, and in particular to devices for ventilation of wagon bodies.

A known ventilation system of a van body of a vehicle, comprising an outlet ventilation device located on the rear panel of the body and an inlet ventilation device located on the front panel of the body, consisting of a body, a cover, a drainage system and a valve mechanism (RU patent No. 2104169).

The disadvantages of this device include:

- low degree of purification of the incoming air;

- significant dimensions of the actuator and drainage system, which reduce the usable volume of the box body;

- lack of forced ventilation;

- lack of remote control, which requires significant time costs for changing the intensity of the air supply.

The aim of the invention is to increase the degree of purification of the incoming air, reducing the overall dimensions of the system, increasing the convenience of controlling the system, as well as providing forced ventilation of the box body during parking and when the vehicle is moving at low speeds.

This goal is achieved by the ventilation system of the van body of the vehicle, comprising an outlet ventilation device located on the rear panel of the body and an inlet ventilation device located on the front panel of the body, each of which consists of a housing with drainage holes, an external grille with shutters, controlled an electromagnet and a system of servos, an electric fan, a replaceable filter element and an internal grill, allows for the supply and removal of moisture and particles free from moisture dust of air into the volume of the wagon body both when driving and when the vehicle is stationary, while it has smaller overall dimensions and does not reduce the internal usable volume of the wagon body.

In FIG. 1 shows a layout diagram of a ventilation system of a van; in FIG. 2 - inlet ventilation device in section; in FIG. 3 is a general view of the inlet ventilation device.

The ventilation system of the van body of the vehicle includes an output device for air mounted on the rear panel of the van body, and an input mounted on the front panel of the van body 1. The input and output devices are identical in their design. The ventilation device consists of a housing 2 with drainage holes 3, an external grill 4 with shutters 5 controlled by an electromagnet 6 and a servo system 7, an electric fan 8, a replaceable filter element 9 and an internal grill 10.

The system operates as follows.

The inlet ventilation device is located on the front panel of the body in the area where the high-pressure air pressure creates the greatest excess pressure; the output device is mounted in the rear of the body in the vacuum zone. Intensive purging of the internal volume of the van body takes place in the direction from the front panel to the rear. The ventilation intensity is changed by changing the areas of the inlet and outlet openings of the system due to the position of the blinds 5, controlled by an electromagnet 6 and servos 7. The replaceable filter element 9 is fixed using an internal grill 10 and prevents dust particles from entering the van body. Blinds 5, installed at a reciprocal angle to the incoming air flow, as well as drainage holes 3, made at a slope towards the outer panel of the van body, to prevent water droplets from entering the inner volume of the van body 1. When the vehicle is stationary, as well as when at low speeds, the ventilation of the internal volume of the van body is provided by electric fans 8 with a variable speed, which, like the electromagnet 6, are controlled by a remote control Established by either the cab of the vehicle, either directly in the vans. In addition, the control of the ventilation system of the van body can be carried out automatically, for example, when the climate control technology of the van body is turned on, the blinds 5 of the input and output devices are automatically closed.

The proposed device allows for the ventilation of the van body even during parking, to increase the degree of purification of the incoming air, to reduce the overall dimensions of the system, as well as to remotely control the intensity of the air flow.

Claims (1)
