A joining method of an aluminum member to a dissimilar metal member excluding copper by brazing or soldering through the use of a brazing filler metal or a solder for aluminum member; in which a plating composed of a metal voluntarily selected from copper, aluminum, zinc, lead, silicon, cadmium, tin and an alloy having major component of two or more kinds of them, is previously applied on a surface of joined portion of the dissimilar metal member, the plated joined portion of the dissimilar metal member is dipped in a molten brazing filler metal or a molten solder and ultrasonic vibration is given to the joined portion to stick the brazing filler metal or the solder to the joined portion, and a brazing or a soldering is carried out thereafter.

Joining method of aluminum member to dissimilar metal member

A heat-pipe device for transferring heat generated by a heat-generating element, having at least one heat-pipe body which is an extrudate of plate-like configuration made of aluminum or its alloy, the heat-pipe body including a planer-structure portion which has on one side thereof a flat face to which the heat-generating element is directly fixed, the heat-pipe body further including a plurality of passage-defining portions which protrude from the other side of the planer-structure portion and extend parallel to, and apart a predetermined distance from, each other, each passage-defining portion having therein a flow passage which is fluid-tightly charged with a working fluid for transferring the heat generated by the heat-generating element. Also is disclosed a heat-sink device for cooling a heat-generating element, having at least one heat-pipe body including a planer-structure portion and a plurality of passage-defining portions. The heat-sink device may further have a header pipe, and the heat-pipe body may be bent to form a box-like configuration such that the longitudinal ends of flow passages within the passage-defining portions are open in a communication passage within the header pipe. The heat-sink device may further have a first and second header pipe, and the heat-pipe body may be disposed vertical such that the flow passages run in a horizontal direction and are open in a first and second communication passages within the first and second header pipes.

Heat-pipe device and heat-sink device

An evaporator for refrigerators and the like, comprising a sheet and at least one refrigerant flow passage assembly which includes a multi-passage unit having a plurality of parallel flow passages, an inlet header pipe connected to the inlet openings of the flow passages and an outlet header pipe connected to the outlet openings of the flow passages. The sheet which carries on one surface thereof the passage assembly or assemblies is bent to form a rectangular box-like structure of a cooler for a freezing chamber formed in the refrigerators.
