摘要： A heat exchanger includes fins (111) having a plurality of sets of two louvres (111c) substantially triangular in shape which are formed in such a manner that the distance from a flat plate portion (111a) increases progressively downstream in the gas flow direction. The two louvres (111c) of each set are arranged inwardly slanted along the gas flow direction, so that a vertical swirl is generated to draw the gas flow between the louvres (111c). The gas flowing in the vicinity of the flat plate portion (111a) and the gas flowing in the vicinity of a vertical plate portion (111b) are thus accelerated. As a result, the heat conductivity of the gas and the fins (111) is improved and the particulate matter attached on the surface of the fins (111) can be blown off, thereby preventing the clogging of the fins (111).

摘要： Exhaust gases enter the heat exchanger at an entry (141) and leaves at an exit (142). Cooling water enters through a pipe (151) and leaves through a second pipe (152). The exhaust gases and cooling water pass along parallel interleaved passages and the exhaust gas channels contain fins (111) to aid heat transfer. The fins are more widely spaced downstream than upstream but not more than twice as widely spaced.

摘要： The heat exchanger has a core area (130) for effecting heat exchange between first and second fluids and containing multiple small pipes (120) forming an internal through passage for the first fluid. The small pipes form several spaces (112) between them. Ribs (111) are arranged in a space between adjacent pipes, in order to facilitate heat exchange between the first and second fluids. A core housing (143) contains the core area and forms a second through passage, which contains the several spaces through which the second fluid flows. A flow guide component (113) in the second through passage prevents the second fluid by-passing the several spaces between adjacent small pipes. The first fluid is a coolant and the second fluid is the exhaust gas from an internal combustion engine.

摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger with high pressure resistance.
SOLUTION: The heat exchanger includes: flat tubes 10 superposed on each other; an inlet header part 50 connected to one end parts of the respective flat tubes 10 and having an inflow port 53 for making cooling water flow in from outside; an outlet header part 60 connected to the other end parts of the respective flat tubes 10 and having an outflow port 63 for making cooling water flow out to outside; inserts 70, 80 arranged in both end parts in the superposing direction of the flat tubes 10 and connected to the inlet header part 50 and the outlet header part 60; and ribs 71, 81 formed by bending both end parts of the respective inserts 70, 80 outwardly. The height of the ribs 71, 81 is set to gradually increase from the inlet header part 50 side to a portion near the longitudinal direction central part of the insert 70, 80 and gradually decrease from the portion near the longitudinal direction central part of the insert 70, 80 toward the outlet header part 60 side.

摘要： PROBLEM TO BE SOLVED: To prevent lowering of cooling capacity of an EGR cooler. SOLUTION: A guide protruding portion 120b for directing a cooling flow of water which has flowed into a cooling water passage 120 from a cooling water communicating path 120a, is provided at a diagonal portion in the passage 120, opposite to the diagonal portion wherein the path 120a is provided. Thus, the diagonal portion opposite to the diagonal portion wherein the path 120a is provided, can be prevented from becoming a dead water region (stagnant pool). Accordingly, in the diagonal portion opposite to the diagonal portion wherein the path 120a is provided, cooling water can be prevented from being boiled, thereby preventing the cooling capacity of the EGR cooler from being drastically lowered.
