Abstract: An outdoor cooling unit in a vehicle air-conditioning apparatus is configured such that the angle between a normal line to a suction plane of a suction portion and a normal line to a discharge plane of a discharge portion is acute and such that air inside a housing flows in a substantially checkmark-shape, substantially V shape or substantially U shape. In the outdoor cooling unit, a blade of an axial fan is configured such that a chord center line formed by connecting chord central points from an inner circumferential end to an outer circumferential end of the blade and projecting the connected chord central points on a plane containing a rotating shaft is convexly curved toward the downstream side over the entire area in the radial direction.

Abstract: To enhance the positioning accuracy between primary members and auxiliary members without need of latch parts such as rivets, an insertion frame structure includes: a pair of primary members having L-shaped cross-sections and placed with the L shapes facing to each other symmetrically; and several auxiliary members having angular U-shaped cross-sections between the primary members. The primary members and the auxiliary members are joined at latch portions. The latch portions of the primary members have clearance-shaped latch holes. The latch portions of the auxiliary members have convex portions to be inserted into the latch holes. Each latch hole has a clearance with a larger dimension than a plate thickness t of the auxiliary members, and continuously from the clearance, a clearance with a dimension smaller than the plate thickness t of the auxiliary members.

Abstract: Provided is an air-conditioning apparatus for vehicle including a main frame capable of being assembled without increasing the number of parts and the number of processes. An air-conditioning apparatus for vehicle includes a casing divided into an indoor chamber and an outdoor chamber by a partition plate, the casing including a cover placed on a top thereof, and a refrigeration cycle device placed across the indoor chamber and the outdoor chamber in the casing. Each of side plates, serving as side surfaces of the indoor chamber and the outdoor chamber, of the casing is extruded in one piece of aluminum.

Abstract: An assembling method of a vehicular air-conditioning apparatus including various equipment, which is required for air-conditioning a vehicle, mounted in a vehicular-air-conditioner frame on a production line includes modularization of, among the various equipment, at least a compressor, an indoor heat exchanger, and an outdoor heat exchanger off the production line, and, further, modularization of a refrigeration cycle by connecting the above modules with refrigerant pipes off the production line, as well as incorporating the modularized refrigerant cycle into assembly work on the production line as a refrigerant cycle module.

Abstract: A heat exchanger for a vehicle air-conditioner includes a plurality of fins arranged parallel to one another and a plurality of heat transfer tubes extending parallel to one another through the fins. The fins are cut by a corrugated cutter from a band material having through-holes through which the heat transfer tubes are to extend. A row pitch Dp of the heat transfer tubes is expressed as “Dp=C+D+2W+28 for 0<?<D+W” where C is the thickness of the cutter, D is the outside diameter of the heat transfer tube, W is the width of a fin collar flange projecting outwards from the tip of a fin collar extending from the edge of each of the through-holes to one side of each of the fins, and 6 is the clearance between the cutter and the fin collar flange.

Abstract: A management system for vehicle air-conditioning and a method of managing the same are provided. Changes of a temperature in a vehicle from various environmental information, between a standard for showing a comfortable environment in the vehicle and actual environment information, are recognized to identify abnormalities occurring in components at an early stage and to appropriately judge the necessity and urgency of maintenance. A management system of vehicle air-conditioning includes an air-conditioning controller that predicts abnormalities of components of the refrigeration cycle by comparing a temperature in the vehicle obtained when the refrigeration cycle is actually driven with a preset temperature in the vehicle that constitutes a standard.
