Abstract
A shell-tube heat exchanger for recovering waste heat of an engine is used for absorbing the waste heat discharged by the engine, the absorbed heat is used for heating cold air entering a combustion chamber of the engine through a tube shell, mechanical equivalent of heat of the combustion chamber is increased, and output power of the engine is improved. An indispensable energy source is provided for a future engine oil saving technology. Finned tubes are formed by winding metal sheets on metal tubes and firmly welding the metal sheets on the metal tubes by high-frequency welding. When high-temperature exhaust gas discharged from the combustion chamber of the engine flows through inner walls of the finned tubes via a pipeline and flanges, heat is absorbed by the walls of the finned tubes and conducted to cold air flowing through outside the walls of the finned tubes, and the cold air medium flows between the tube shell of the heat exchanger and the finned tubes. The cold air flows into an air inlet system of the combustion chamber of the engine through the pipeline and the flanges after being heated.
Description
Affiliated technical field:
The present invention relates to a kind of engine exhaust heat and reclaim the shell heat exchanger apparatus, is the equipment that a kind of waste-gas heat of discharging by motor is absorbed specifically.
Background technique:
The motor of current use mostly is that the useless flue gas after the acting directly is discharged in the atmosphere, and this is a kind of energy waste.
Summary of the invention:
The present invention has designed a kind of engine exhaust heat to reclaim shell-and-tube heat exchanger for above deficiency, be used for realizing absorbing heat, and the heat that absorbs entered the cool air of engine chamber by the shell heating, and increase the mechanical equivalent of heat of firing chamber, improve engine output.For later engines fuel-economizing technology provides indispensable energy source.
In order to reach the order ground that addresses the above problem, engine exhaust heat reclaims shell-and-tube heat exchanger and comprises: inlet of cold air adpting flange, outer cover of heat exchanger, high-temperature flue gas import adpting flange, fin tube, dividing plate, low-temperature flue gas outlet adpting flange, the hot air outlet adpting flange.This engine exhaust heat reclaims shell-and-tube heat exchanger and can be circular, also can be other shapes.This fin tube is that sheet metal is wrapped on the metal tube, and firmly is welded on the metal tube with highfrequency welding.When the high-temp waste gas of engine chamber discharge flow through the fin tube inwall by pipeline and flange, heat was absorbed and conducts the cool air that flows through to the fin tube tube wall exterior by the fin tube tube wall, and this cool air media flow is between heat exchanger shell and fin tube.Flow to the engine chamber gas handling system by the flange pipeline after the cool air heating.
Brief Description Of Drawings:
Accompanying drawing is the sectional drawing that engine exhaust heat reclaims shell-and-tube heat exchanger.
Among the figure: 1, inlet of cold air adpting flange,
2, outer cover of heat exchanger,
3, high-temperature flue gas import adpting flange,
4, fin tube,
5, dividing plate,
6, low-temperature flue gas outlet adpting flange,
7, the hot air outlet adpting flange.
The high-temperature flue gas of discharging when engine chamber enters in the fin tube 4 via high-temperature flue gas import adpting flange 3, and heat is conducted to discharging on the tube wall of fin tube 4 and from low-temperature flue gas outlet adpting flange 6.Cool air enters in the outer cover of heat exchanger 2 via inlet of cold air adpting flange 1 and between the fin tube 4 time, with the exchange of absorbing heat of fin tube heat, heated air flows out via hot air outlet adpting flange 7 and enters into the motor suction system under dividing plate 5 effects.
Specific implementation method:
As shown in the figure: inlet of cold air adpting flange 1 is connected on the outer cover of heat exchanger 2, high-temperature flue gas import adpting flange 3 is connected on the outer cover of heat exchanger 2, low-temperature flue gas outlet adpting flange 6 is connected on the outer cover of heat exchanger 2, hot air outlet adpting flange 7 is connected on the outer cover of heat exchanger 2, fin tube 4 is connected on the dividing plate 5, and dividing plate 5 is connected on the outer cover of heat exchanger 2.
