SU1645802A1 - Heat exchanger - Google Patents

Abstract

The invention relates to a power system, can be used to cool the circulating water of industrial enterprises and power plants and allows to increase the efficiency of heat exchange. The heat exchanger comprises a housing 1 with inlet and outlet pipelines 2, 3 with a cooled heat carrier. The coolant with the help of a ring collector 5 is distributed along a series-connected horizontal sections 7 of a zigzag tubular array. Vertically ribbed heat pipes 10 are installed between sections 7. The evaporative zone of pipe 10 is installed inside the underlying section 7, and its condensation zone adjoins to upper section 7 through a heat insulating gasket. Heated coolant (for example, cold air) flows from below through channels 9 and cools the coolant to sections 7. 2 ill. AT

Description

The invention relates to a power system and can be used to cool the circulating water of industrial enterprises and power plants.

The purpose of the invention is to increase the efficiency of heat transfer.

In FIG. 1 shows a heat exchanger, general view; in FIG. 2 - installation of a heat pipe.

The heat exchanger includes a housing 1 with a supply pipe 2, the discharge pipes 3 with a cooled coolant, such as water. The pipeline 2 (with hot water) is connected to the central riser 4 with an annular collector 6. In the housing 1 there is a zigzag pipe matrix having horizontal sections located in tiers and interconnected by elements 6 7. The latter are connected to the collectors

8. In the lower part of the housing 1 there are channels (windows) 9 for supplying a heating medium, for example air. In the upper part of the housing 1 there is a channel for air exhaust (not shown). Between the horizontal sections 7 vertically installed heat pipes 10 with ribs 11, filled with low-boiling intermediate coolant. The evaporation zone 12 of the pipe 10 is installed inside the section 7 of the lower tier. The condensation zone 13 of the pipe 10 is adjacent through a heat-insulating gasket 14 to the section 7 of the upper tier. A blind partition 15 is installed under the tube matrix and its central part.

The coolant to be cooled, for example hot water, is distributed via a collector 5 along a zigzag pipe matrix into sections connected in series 7. The water is exposed to the cooling effect of air entering the housing 1 from the bottom up. Using vertically mounted finned coarse coarse 10 provides additional heat removal from the fluid sequentially passing through sections 7.
