Problems solved by technology

[0010] However, since the position of the refrigerant passage hole cannot be recognized from the outside when the assembly is assembled to manufacture the evaporator, it is possible to longitudinally incorporate the resistance plate into the assembly in the opposite direction.
Therefore, the effect of making the refrigerant flow through all the heat exchange tubes in a uniform amount can hardly be obtained, and there is a possibility that the cooling performance of the evaporator is greatly impaired

Abstract

A heat exchanger (1), comprising: a heat exchange core (4) composed of a plurality of heat exchange tubes (9), a refrigerant inlet header (5) arranged toward one end of each heat exchange tube, and a refrigeration A refrigerant outlet header (6), and a refrigerant inflow header (7) and a refrigerant outflow header (8) disposed toward the other end of each heat exchange tube. The interior of the outlet header on which some of the heat exchange tubes are joined to communicate with the space (6b) is divided into two spaces (6a, 6b) by a flow-dividing resistance plate (26). A plurality of refrigerant circulation holes (27A-27D) having different shapes and / or sizes are formed in the resistance plate (26). The outlet headers have markings (28A-28D) on the outer surface for identifying the location of the refrigerant flow holes (27A-27D) and representing the shape and / or size of said holes. The heat exchanger exhibits high heat exchange performance when used as an evaporator.

Description

[0001] Cross References to Related Applications [0002] This application was filed pursuant to 35 U.S.C. §111(a) and was filed under 35 U.S.C. §119(e)(1) on August 25, 2003 and March 24, 2004, respectively, under 35 U.S.C. §111(b) ) filing date benefits of provisional applications No. 60 / 497338 and No. 60 / 555706 filed. technical field [0003] The invention relates to a heat exchanger, in particular to a heat exchanger used as an evaporator in a motor vehicle air conditioner, ie a refrigeration cycle installed in a motor vehicle. [0004] The downstream side of the air to pass through the airflow gap between each pair of adjacent heat exchange tubes ( figure 1 and 10 the direction indicated by the arrow X, and image 3 and 11 The right-hand side of ) is referred to herein and in the appended claims as "front" and the opposite side is referred to as "rear". Background technique [0005] Hitherto, so-called stacked-plate evaporators are widely used as motor vehicle evapo...
