Description

Helicopter short wing with condenser assembly

Technical field

The present invention relates to a helicopter air conditioning system, and in particular to a helicopter short wing with a condenser assembly.

Background technique

In recent years, helicopters have been increasingly used in rescue, law enforcement, agriculture, military, transportation and other fields. With the development of helicopters, the number of high-power electronic equipment on board is increasing day by day, and the requirements of passengers for cabin comfort and cooling of electronic equipment are increasing day by day. The importance of helicopter environmental control systems has become increasingly prominent. Moreover, foreign high-performance civilian and military helicopters are equipped with environmental control systems with relatively complete performance, so the domestic development of supporting helicopter environmental control systems is of great significance.

Compared with fixed-wing aircraft, helicopters fly at lower altitudes and at slower speeds, and do not require cabin pressurization. In addition, helicopter environmental control systems are generally installed on models that have been designed and produced. At the beginning of the design, most helicopters did not consider the compensation loss of the environmental control system, and the system weight and installation space were limited. Therefore, when designing the helicopter environmental control system, the system weight should be reduced as much as possible while improving the system efficiency.

It is understood that the existing air-conditioning and refrigeration systems of existing helicopters have shortcomings such as insufficient cooling capacity, bulky systems, and complicated installation. One of the reasons for insufficient cooling capacity is that the air flow organization on the condenser side is not smooth, the heat exchange area of the condenser is not fully utilized, and the heat exchange effect between the air and the condenser is poor.

Detailed ways

The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings:

The invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, components are exaggerated for clarity.

As shown in Figure 1, the present invention discloses a helicopter short wing with a condenser assembly, which includes a short wing body 1, a condenser 2, an air duct 3, a fan 4 and an anti-collision net 6;

The short wing body 1 is provided with a cavity and a partition that divides the cavity into an inner cavity and an outer cavity. The partition is provided with through holes for ventilation of the inner cavity and the outer cavity;

The shell of the short wing body 1 is provided with a through hole communicating with the outer cavity;

The anti-collision net 6 is provided at the through hole on the housing of the short wing body 1 to prevent foreign matter from entering the short wing body 1;

The air duct 3 is a cylinder with both ends open in the outer cavity, one end of which is fixedly connected to the shell of the short wing body 1, and the through hole on the shell of the short wing body 1 is included in it. inside; the other end is fixedly connected to the condenser 2;

The fan 4 is arranged in the air duct 3 and is fixedly connected to the shell of the short wing body 1, and is used to pass the air in the outer cavity through the condenser 2, the air duct 3, and the short wing body 1 shell in sequence. The through hole on the top discharges outward.
