Abstract

PURPOSE:To prevent leaking of sound generated outside by employing a double shall structure of inlet and outlet intake headers where the front and rear sides of a heat exchanging section are covered with plate-shaped bodies forming a header for cooling water. CONSTITUTION:Header bodies 12 and 13 are both a double shell structure respectively comprising outer shells 12a and 13a and inner shells 12b and 13b. A space for proofing sound is formed between the outer shells 12a and 13a and the inner shells 12b and 13b. Hot intake air enters a header 11 on the side of an outlet for suction via an intake port 16 and flows upward inside the header being dispersed to each flat pipe 2 to be discharged at an intake outlet 15 via the inside of a header 10 on the side of an outlet for suction. On the other hand, a cooling water enters a header 20 on the side of an inlet for cooling water via a cooling water supply port 21. Thereafter, with actions of middle headers 24, 25 and 26 and bars 7 and 8, the cooling water flows through a zigzag path P and enters a header 22 on the side of an outlet for cooling water to be discharged at a discharge port 23. Thus, a hot intake is cooled down by the cooling water flowing through a cooling water passage section 5 when flowing through the flat pipe 2.

The reason why such a problem occurs is considered to be due to the following reasons. In other words, the heat possessed by high-temperature intake air is
This heat is transmitted to the cooling water through the peripheral wall of the hollow body, and first the temperature of the cooling water near the peripheral wall of the hollow body increases, but the temperature of the portion of the cooling water flowing through the center of the hollow body does not become so high. In this state, the heat transfer coefficient from intake air to cooling water decreases. And the cooling water
If the cooling water flows in a straight line from the inlet header to the outlet header in the hollow body, the high temperature part near the peripheral wall of the hollow body and the low temperature part in the center of the hollow body will not be effectively stirred. , it reaches the outlet side header in this state, so it is considered that sufficient cooling efficiency cannot be obtained.
