IPC: G01N27/409
Filed: 1983-07-13
Abstract: PURPOSE:To obtain an oxygen sensor which is made inexpensive by the reduction of a platinum amount, fast in rising and prevented from the lowering in life, by applying a platinum electrode only to the leading end of the oxygen sensor, and by allowing an electrode lead part to position in a side not contacted with a flame. CONSTITUTION:An inner surface side platinum electrode 2 and an outer surface side platinum electrode 3 are applied to the entire periphery of the leading end part of a sensor. Electrode lead parts 8, 9 to the connection part of the electrodes 2, 3 and lead wires 7 are provided to a part of the periphery of the sensor and extend linearly to the axial direction thereof. In this case, the sensor is arranged so as to prevent the electrode lead parts 8, 9 from contacting with a flame A. By this structure, the amount to be used of platinum is reduced to make the sensor inexpensive and the rising of the sensor also becomes fast. In addition, because the electrode lead parts are not contacted with a flame A, the same life as one, wherein the electrodes 2, 3 are applied to the entire periphery of a sensor, is obtained.

Further, groups of upright shaved parts 9, which lie in rows of the groups of the upright shaved parts 10, are arranged around the heat transfer pipe. The arrangement of a plurality of the cut-and-rised parts 9 and 10 on the flat fin 5 is equal to the state that a plurality of short fins stood in the direction of air flow on the flat fin 5. A thin temperature boundary layer is formed on each of said short fins, the air side heat transfer rate is remarkably improved due to the so-called leading edge effect.
