Internal jet inpingement type shell and tube heat exchanger
This invention relates to an internal jet impingement type shell and tube heat exchanger in which the jet cooling tubes and the heating tubes in shell and tube heat exchanger are formed either as a staggered tube bundle or as a square tube bundle, and the orifices on each jet cooling tube are provided according to the arrangement of tube bundle. Thus, the heat transfer performance of jet impingement type shell and tube heat exchanger is remarkably enhanced.
1. An internal jet impingement type shell and tube heat exchanger, comprising the heating tubes and the jet cooling tubes are provided therein, wherein all said heating tubes and said jet cooling tubes are formed as a staggered tube bundle, the 1 st row being provided with jet cooling tubes which form triangular arrangement with the heating tubes of the 2 nd row, one jet cooling tube being interposed between every two heating tubes in the 3 rd , 5 th , 7 th . . . rows, each jet cooling tube being provided with orifices directing to each adjacent heating tube.
