Abstract

PURPOSE:To enable attaching and detaching of a cooler as requested and stable running of a car by internally mounting a housing in which a refrigeration cycle unit of the cooler and the driving motor of a compressor in the opening provided on a dash panel so as to be attached and detached. CONSTITUTION:When a cooler housing 3 is mounted on the surface of a dash panel 1, a nipple is connected to the oil feed tube of a main engine and an exhaust manifold side, and a plug receptacle is also connected to the feed line of an engine room, a cooler is set in a movable state. Then, when the nipple and the plug receptacle are removed when not required and the flange section 3a of the cooler housing 3 is also removed from an opening 1a, an air intake duct for circulating inside air is closed. Furthermore, when the cooler housing 3 is removed and then the opening 1a is covered with a lid 6, the removal work of the cooler is completed. As a result, since a compressor is driven by an independent driving system, stable running can be obtained with little rotary variation and without any load variation resulting from the disconnection of a clutch.

However, in such a cooler, when the car is driven at high speed, the rotation speed of the compressor increases, which tends to overcool the vehicle interior, and conversely, a correspondingly large load is applied to the engine side. Furthermore, coolers are only used from mid-spring to mid-autumn at most, and are not used for about half of the year.

Therefore, the cooler is rather a nuisance during the cold season, and has a large effect on the weight of the vehicle.

Further, in this invention, since the compressor is driven by an independent drive system separate from the automobile engine, there is no rotational fluctuation of the compressor due to engine rotational fluctuation.
The cooler can be driven in a stable state at all times. On the other hand, on the engine side of the automobile, there is no load fluctuation due to clutch engagement and engagement, and stable driving can be achieved.
