BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiver / dryer integrated capacitor, and more particularly to a receiver / dryer integrated capacitor capable of improving the workability of assembling the receiver / dryer when mounting on a vehicle. .

[0002]

2. Description of the Related Art In recent years, it has been required to simplify the work of assembling various parts to a vehicle. Especially, cooling system parts (air conditioner parts) in the refrigeration cycle, such as condensers and receiver dryers, which are arranged in the front part of the engine room called the front end of the vehicle, are arranged in the limited space of the engine room and the fixing structure is also provided As a result, it is basically necessary to assemble them to the vehicle body, so it is not possible to assemble them into the engine in advance, and the need to simplify the assembly work in the engine room becomes stronger than other parts. ing.

However, in order to assemble air conditioner parts such as condensers and receiver dryers, fixing brackets, various pipes, connections of hoses and pipes, etc.
There is a problem that difficult work is required in a narrow space.

As a structure for integrating the receiver dryer and the capacitor, Japanese Patent Laid-Open No. 4-254171,
There is JP-A-5-87424.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and can greatly simplify the work of assembling a cooling system component such as a condenser and a receiver dryer into a vehicle. An object is to provide a dryer-integrated capacitor.

Further, the present invention eliminates the condenser and receiver dryer fixing brackets, integrates the fan and its shroud together, and further simplifies the connection work of the refrigerant hose and piping. The challenge is to provide.

It is another object of the present invention to provide a receiver / dryer integrated capacitor which can be assembled with a single fixing bolt.

[0008]

That is, the present invention is for fixing a receiver dryer to a fan shroud (fan fixing cover) without using a fixing bracket dedicated to the receiver dryer and the condenser. Focusing on forming a receiving part and providing a capacitor connector capable of connecting a condenser and a receiver dryer, a receiver dryer integrated type capacitor in which a receiver dryer is integrally assembled with a condenser of a refrigeration cycle, A fan shroud that pushes air into the condenser, a receiver dryer fixing receiving portion provided in the shroud, and an assembling through hole formed in the shroud, and the condenser and the receiver dryer can be connected. Capacitor And compactors, a receiver drier integrated capacitor and having a fixed bolt fixable to the capacitor and the receiver-drier through the capacitor connector.

By forming an inlet passage and an outlet passage for the refrigerant in the condenser connector, the hose and piping between the condenser and the receiver dryer can be omitted or simplified. This inlet passage is from the refrigerant pressure hose connected to the compressor to the condenser. As the outlet passage, there is a passage from the condenser to the receiver dryer or, in some embodiments, a passage from the receiver dryer to the refrigerant pressure hose on the expansion valve side.

By forming the receiver dryer fixing receiving portion at the header tank portion of the condenser, the receiver dryer does not cover the heat exchanging portion (tube portion) of the condenser, and the heat exchanging portion is not covered. There is no resistance to the air passing through.

The fan may be of a push type in which air can be pushed in the direction of the condenser. In addition, the fan is arranged in front of the condenser together with the shroud and the wind flow in front of the condenser is adjusted to adjust the receiver. It is possible to prevent the deterioration of the condenser cooling performance due to the turbulence of the wind caused by the dryer.

By integrally assembling the receiver / dryer integrated capacitor integrated with the fan and the shroud with the radiator of the engine, the assembling work can be further simplified.

In the receiver dryer integrated capacitor according to the present invention, the receiver dryer fixing receiving portion is provided in the shroud of the fan, and the capacitor and the receiver dryer are connected via the capacitor connector inserted in the assembly through hole formed in the shroud. Since it can be fixed by the fixing bolt, the work of assembling the fan and its shroud, condenser and receiver dryer to the vehicle can be greatly simplified. In particular, since the condenser and the receiver dryer can be integrally assembled with at least one fixing bolt, workability is good even in a narrow space of the engine room. In addition, before assembling the fan, shroud, condenser, receiver dryer, etc. before assembling into the vehicle and then assembling into the vehicle as one unit, the assembly work of the unit can be simplified. There is an advantage.

Furthermore, the exclusive fixing brackets for the receiver dryer and the condenser can be eliminated, and the cost can be reduced.
