A heat exchanger, as mounted on the outdoor unit or indoor unit of an air conditioner system, is formed with a plurality of passages for a refrigerant. To this heat exchanger, there is connected a refrigerant distributor for distributing the refrigerant to the individual passages or for collecting the distributed refrigerant. This refrigerant distributor is constructed by soldering two corrugated plate members to form a refrigerant conduit between the corrugations. Before these plate members are soldered, the refrigerant conduit is either partially constricted to form a throttle portion or partially bulged to form a filter portion by fitting a filter member in the bulging portion when the plate members are soldered. Thus, the refrigerant distributor can set the diversion of the refrigerant to a predetermined ratio by the simple device while reducing the space and lowering the cost.

In a high-rigidity structure made of sheet metal, in order to prevent increases of vibrations and noises owing to deterioration of the rigidity caused by decreasing the thickness of the sheet-metal, ribs having a height 10 times or more larger than the sheet-metal thickness are formed on bent portions of the sheet-metal structure, corrugated continuous grooves having two or more crest portions are formed on a surface of each of the bent portions on a smaller-radius side, and concave/convex sections corresponding to the continuous grooves are formed on side surfaces of each of the ribs which connect a larger-radius side and the smaller-radius side.

An embedded-type handle assembly may have its lock bars arranged either horizontally or vertically. In the assembly: a shaft 9 is rotatably inserted in a cylindrical bearing portion 8 of a casing 1; a link plate 18 has a circular hole 16 through which the link plate 18 is mounted on the shaft 9 in an insertion manner; a lock bar 20 has its base-end portion connected with one end 19 of the link plate 18 through a pivot 27; a lock bar 23 has its base-end portion connected with the other end 22 of the link plate 18 through a pivot 28; the link plate 18 has a follower surface 25 in a side surface of the other end portion 22, the surface 25 being pushed by the operating-foot plate 5 of the handle 2; and, the link plate 18 has a follower projection 26 in a side surface of its intermediate portion, the projection 26 being pushed by the operating-foot plate 5 of the handle 2.
