Abstract
PURPOSE: To improve heat exchange performance by a method wherein a sectional area of a passage for a fluid to heat in a heat exchanger working on an engine exhaust heat is widened downstream, a rate of flow is increased to improve heat transfer at the upper stream but decreased to reduce pressure loss at the downstream.
CONSTITUTION: A plurality of guides 32 are arranged in parallel in a frame 30 of a heat exchanger 34 in such manner as will have the intervals widened in accordance as a fluid to heat comes downstream, an they are extended alternately from longitudinal ends. According to this constitution, the fluid fed from a supply port 19A is minimized for the quantity of flow at the upper stream side and thus flows at high speed to a turbulent flow, thereby bringing a high heating performance; the fluid is then increased for the quantity of flow in accordance as it comes downstream and thus flows at low speed, thereby minimizing a pressure loss. Heat exchange performance can therefore be improved.
