Abstract

PURPOSE:To make it possible to reduce the welded parts, to easily manufacture the heat exchanger at inexpensive cost and further to reduce the amount of leaked water by forming header parts so that they are integrally assembled on both right and left sides of each of first and second fluid flowpaths. CONSTITUTION:Oil flows through a first fluid flowpath A and air flows through a second fluid flowpath B. Both flowpaths A and B are disposed so that the fluids flow in a rectangularly intersecting manner, and on both right and left sides of the heat exchanger 1 header parts 2 and 2 are integrally formed. The first fluid flowpath A is formed by flat plates 3 and 3 disposed at both up and down sides and having fluid passage holes 4 and 4 at both right and left ends, a first fluid flowpath forming annular member 5 having outer peripheries of the substantially the same shape as the flat plate, and inner fins 6 made of an aluminum extrusion die material. The second fluid flowpath B is formed by flat plates 3 and 3 having fluid passage holes 4 and 4, a pair of spacers 7 and 7, and corrugated fins 8. Fluid passage holes 9 and 9 communicating with fluid passage holes 4 and 4 of up and down flat plates 3 and 3, are formed in both right and left spacers 7 and 7.

BACKGROUND OF THE INVENTION In recent years, aluminum laminated heat exchangers have been widely used as large oil coolers. In this heat exchanger, a first fluid flow path through which oil passes and a second fluid flow path through which air flows in a direction perpendicular to the first fluid flow path are separated by a flat plate and are arranged vertically alternately. However, in conventional heat exchangers, the tubes constituting the first fluid flow path and the fins housed in the second fluid flow path between the tubes are joined together by vacuum brazing, Other fluid introduction headers, discharge headers, fluid introduction pipes, discharge pipes, and the like have been manufactured by joining together, for example, by argon welding. However, such a conventional heat exchanger has a large number of welding points, and therefore manufacturing thereof is very troublesome and time-consuming, requires skill in welding, and has a high manufacturing cost. In addition, since there are many welding points, liquid leakage is likely to occur due to poor welding, and there is also the problem that so-called spatter (aluminum pieces) generated when welding headers etc. enters the heat exchanger, impairing the performance of the heat exchanger.

Purpose of the Invention The present invention solves the above-mentioned problems, and by forming the header part so as to be integrally incorporated on both the left and right sides of the first and second fluid flow paths, there are very few welded parts, and therefore the manufacturing process can be simplified.

It is an object of the present invention to provide a heat exchanger that can be freely and extremely easily designed to form parallel flows or countercurrent flows, and that can improve heat exchange performance.
