The heat exchange apparatus is substantially tubular in shape and is provided with a divergent inlet section having an angle of divergence less than 10*, and preferably 4* to 7*.，下面是Cooling apparatus and process专利的具体信息内容。
1. A heat exchange apparatus comprising: a divergently shaped inlet section for the flow of hot fluid therethrough configured with a total divergence angle between 4* and 7*; a downstream section for the flow of hot gases passing from the inlet section which downstream section extends from the downstream end of the inlet section and has a constant crosssectional area equal to the cross-sectional area of the downstream end of the divergently shaped inlet section; means for cooling the hot fluid flowing through the heat exchanger apparatus; whereby the flow of the hot gases is substantially turbulencefree during the passage thereof through the heat exchange apparatus.
2. The apparatus of claim 1 wherein the total angle of divergence of the inlet section is 5*.
3. The apparatus of claim 1 wherein the passage for the flow of hot fluid is a centrally disposed tubular structure and the means for cooling the hot fluid flowing therethrough is a cooling chamber arranged therearound.
4. The apparatus of claim 1 wherein the passage for the flow of hot fluid is a centrally disposed tubular structure and the means for cooling the hot fluid flowing therethrough is comprised of an annular array of tubes arranged in direct contact with the outer surface of the centrally disposed chamber.
5. The apparatus of claim 4 further comprising cooling manifolds at each end of the heat exchanger and wherein the annular array of tubes arranged in direct contact with the surface of the centrally disposed chamber communicate with the manifolds.
6. The apparatus as in claim 5 where the cooling manifolds arranged to communicate with the annular array of tubes are toroidal in configuration.
7. The apparatus as in claim 3 wherein the cooling chamber has a coolant inlet located in proximity to the inlet of the centrally disposed chamber for hot fluid and an outlet located in proximity to the outlet of the centrally disposed chamber for hot fluid.
8. The apparatus of claim 7 wherein the cooling chamber surrounds the entire centrally disposed chamber for hot fluid.
9. The apparatus of claim 1 wherein the passage for the flow of hot fluid is annular.
10. The apparatus of claim 9 wherein the increase in cross-sectional area of the divergent inlet section is equivalent to the increase in cross-sectional area per unit length of a conical pipe having an angle of divergence of 5*.
11. The apparatus of claim 9 wherein the means for cooling the hot fluid flowing through the annular passage is a cooling passage arranged concentrically with and interiorly of the inner wall of the annular passage.
12. The apparatus of claim 11 wherein the cooling passage arranged concentrically with and interiorly of the inner wall of the annular passage is Comprised of a tubular central cooling chamber arranged axially in the heat exchanger, which central cooling chamber has an inlet at one end and an outlet at the opposite end; an annular cooling chamber defined by the outer wall of the tubular central chamber and the inner wall of the annular hot fluid passage; and communication means between the tubular central chamber and the annular cooling chamber.
13. The apparatus of claim 12 wherein the diverging inlet for the annular hot fluid passage is defined by a cone extending from the end of the inner wall of the annular hot fluid passage near the hot fluid inlet and a converging wall surrounding the cone, which converging wall extends from the outer wall of the annular hot fluid passage to the hot fluid inlet.
14. The apparatus of claim 13 wherein the cone has an angle of 25* to 30* and the converging wall extending from the outer wall of the annular hot fluid passage surrounding the cone has an angle of 20* to 25*.
15. The apparatus of claim 9 wherein the cone has an angle of 25* to 30* and the converging wall extending from the outer wall of the annular hot fluid passage surrounding the cone has an angle of 20* to 25*.
16. The apparatus of claim 14 further comprising cooling means arranged around the outer wall of the annular hot fluid passage.
17. The apparatus of claim 16 wherein the cooling means arranged around the outer wall of the annular hot fluid passage is a cooling chamber.
18. The apparatus of claim 17 further comprising cooling fins extending from the outer wall of the annular hot fluid passage into the outer cooling chamber.
