摘要:
The apparatus for the production of a thin strip core comprises a spool for winding a ribbon-like thin strip, a clamping device for clamping and moving the ribbon-like thin strip, a winding core driving device for causing the ribbon-like thin strip clamped by the clamping device to be wound in a prescribed length around a winding core, a cutting device for cutting the ribbon-like thin strip after the ribbon-like thin strip has been wound in the prescribed length around the winding core, a welding device for welding the trailing end of the wound thin strip cut off, a releasing device for releasing the connected wound thin strip, and a measuring device for taking the weight of wound thin strip released. This invention can produce the thin strip core quickly because all of the works involved in the production of the thin strip core are automatically carried out without requiring any manual operation. Further, it imparts a fixed weight to all of the wound thin strip of product owing to the procedure which comprises weighing each wound thin strip immediately after the wound thin strip is cut off and setting the number of plies of winding for the next wound thin strip in due consideration of the cycle of thickness of thin strip so that the next wound thin strip will assume the prescribed weight.

A heater for an air conditioner includes plural water tubes and plural refrigerant tubes which are arranged in parallel in an air flow direction. Therefore, the heater can heat air by using at least one of the heating sources while a pressure loss in the heater can be effectively reduced. For example, in a quick-heating mode, high-temperature refrigerant from a refrigerant cycle flows into the heater to heat the blown air, and low-temperature engine-cooling water from an engine bypasses the heater. In this case, thermal leakage from the refrigerant to the engine-cooling water is avoided.

A magnetic core comprises at least one layer of magnetic film composed of an amorphous alloy and an electrically insulating film made of polyimide. Powder materials having a property for alleviating mutual influence between the magnetic thin film and the insulating film during a heat treatment thereof are stuck to a surface of the magnetic film or the insulating film. The magnetic film and the electrically insulating film are alternately wound up in a predetermined shape with powder material interposed therebetween to thereby form a magnetic core.

A plate-type heat exchanger comprises a stack of flat fluid flow tubes each composed of a pair of confronting core plates joined to each other and defining a fluid flow pass therebetween, each of the core plates having an inlet hole for introducing a fluid into the fluid flow pass and an outlet hole for discharging the fluid from the fluid flow pass. Each core plate has a plurality of ribs on an inner wall surface thereof, the ribs on one of the pair of plates being held in contact with the confronting ribs on the other core plate. The ribs are present in the fluid flow pass between the joined core plates in every direction along the inner wall surface of each of the core plates. The fluid flow pass does not have any fluid passage free of ribs. Therefore, the heat exchanger has improved heat transfer efficiency, and the fluid flow tube is mechanically strong or highly resistant to pressure.

A heat-exchanging plate member has a pair of heat-exchanging plates, each of which has projection ribs and fluid passage forming portions arranged alternately. The pair of plates are connected to each other in a manner that the projection ribs formed in the plates, respectively, face outwardly with each other, and the projection ribs formed in one of the plates are connected to the fluid passage forming portions formed in the other of the plates, respectively, at a temperature where the strength of material is not lowered in a connecting process.
