There is. It is considered that such a problem occurs for the following reason. That is, the heat of the high-temperature intake air is transmitted to the cooling water through the peripheral wall of the hollow body, and the heat first increases the temperature of the cooling water near the peripheral wall of the hollow body. The temperature of the flowing part does not rise so much.
In this state, the heat transfer coefficient from the intake air to the cooling water decreases. Then, when the cooling water flows linearly in the hollow body from the inlet side header toward the outlet side header, a portion having a high temperature near the peripheral wall of the hollow body in the cooling water and a portion having a low temperature in a central portion of the hollow body are included. Is not effectively stirred and reaches the outlet side header in this state, so that it is considered that sufficient cooling efficiency cannot be obtained.
