Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2016/056349
Kind Code:
A1
Abstract:
This heat exchanger 10 is provided with an outer tube 11 of cubic shape, and an inner tube 12 of cylindrical shape formed inside the outer tube 11. An exhaust gas channel 12F is formed inside the inner tube 12. The exhaust gas channel 12F is formed so as to connect an exhaust gas inlet port 13 and an exhaust gas outlet port 14. In the outer tube 11, an air channel 11F is formed between the outer peripheral surface of the inner tube 12 and the inner peripheral surface of the outer tube 11. A resistor 17 is provided inside the inner tube 12. The resistor 17 is provided in the exhaust gas channel 12F, between the exhaust gas inlet port 13 and the exhaust gas outlet port 14. The resistor 17 is a partition plate having a plurality of passage holes and blocking the exhaust gas channel 12F. The resistor 17 throttles the exhaust gas channel 12F, increasing the internal pressure in the exhaust gas channel 12F.
