も既知である（特開平２−２９５９４号公報、特開昭６
３−２７３７９１号公報参照）。Conventional Technology For example, in a heat exchanger used in a condenser for a car air conditioner, a plurality of flat tubes are stacked in the thickness direction with fins interposed between them. It is widely known that headers each consisting of one hollow pipe are connected in communication (see Japanese Patent Laid-Open Publication No. 63-34466, etc.). Furthermore, a so-called laminated type header using a plurality of short header units sequentially connected in the length direction is also known (Japanese Patent Laid-Open No. 2-29594, Japanese Patent Laid-Open No. 6
3-273791).

向上を図ることは困難である。Problems to be Solved by the Invention However, for the flat tubes constituting the refrigerant passages of this type of heat exchanger, a multi-hole extruded material commonly referred to as a harmonica tube is used. As long as such a multi-hole extruded material is used, there are restrictions on manufacturing technology to reduce its thickness, and it is difficult to obtain a tube with a height lower than a predetermined value. Therefore, by increasing the distance between adjacent tubes to increase the heat transfer area (surface area of the fins) on the air side, and reducing the air passage resistance in the air circulation gap, we aim to further improve heat exchange performance. That is difficult.

By making the flat tube even thinner and keeping the tube height low, the heat transfer area on the air side is increased within the limited heat exchanger core area, and the air passage resistance in the air circulation gap is reduced. It is an object of the present invention to provide a so-called header type heat exchanger that can further improve heat dissipation performance.

熱交換器。As a means for solving the problem, the present invention has a structure in which a plurality of flat tubes are stacked in the thickness direction with fins interposed between them, and hollow headers are connected to both ends of each tube. In a heat exchanger composed of a plurality of short header units in which both headers are connected between adjacent tubes, each tube and the short header unit connected to both ends thereof are divided into two in the stacking direction. A heat exchanger characterized in that it is formed by stacking a pair of divided units made of integrally molded parts in a facing manner and joining and integrating them.
