Abstract
The utility model discloses a LNG fuel air feed turbocharging system's backward flow formula heat exchanger for car, the seamless pipeline, heat transfer fin and the return bend that move including the liquid steam flow, the liquid steam flow moves the pipeline has a plurality of compound modes respectively with the hookup return bend, after using the mode of brazing hookup, forms the liquid steam flow and moves the backward flow formula heat exchanger of compriseing following current, crossing current, three kinds of modes of water conservancy diversion. The utility model has the characteristics of heat exchange efficiency is high, liquid - the vapour conversion performance is good, system's pressure boost is stable, the operation is reliable, can wide application in car LNG fuel turbocharging system's heat exchanger manufacturing.
Description
Technical field
The utility model relates to the heat exchanger assembly of automobile LNG fuel air feed pressure charging system, particularly relates to a kind of reverse-flow type heat exchanger combining structure of automobile LNG fuel pressure boost system.
Background technology
The automobile works fine performance of LNG fuel air feed pressure charging system heat exchanger assembly is the important leverage for adopting the car steering of LNG fuel to provide sufficient power.Existing automobile LNG fuel air feed pressure charging system heat exchanger assembly, all adopt the form of flat flow combining structure, this easily brings the phenomenons such as heat transfer effect is poor, liquid gasification is not enough, pressure transient, affects normal work and the operation of engine during running car.
Summary of the invention
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, provides a kind of automobile LNG fuel air feed pressure charging system heat exchanger, makes it have the features such as heat exchange efficiency is high, liquid-vapour conversion performance is good, system boost is stable, reliable.
The technical solution of the utility model is for this reason, the automobile reverse-flow type heat exchanger of LNG fuel air feed pressure charging system, comprise many seamless pipelines, it is characterized in that: many seamless pipelines are a reverse-flow type heat exchanger by the series connection of multiple bend pipe head and the tail, and be wound around in the outside of seamless pipeline or be set with fin, wherein seamless pipeline and bend pipe adopt the mode of soldering to weld.
Further improvement is: described seamless pipeline is more than four, and corresponding bend pipe is no less than three.
Further improvement is: the seamless pipeline arrangement after assembling fin adopts the spread pattern be parallel to each other, and head and the tail series connection is integrated.
Beneficial effect:
The reverse-flow type heat exchanger of automobile LNG fuel air feed pressure charging system of the present utility model, possess that heat exchange efficiency is high, liquid-vapour conversion performance is good, system boost is stablized, reliable advantage, be specially adapted to the application function requirement of automobile LNG air feed pressure charging system, effectively improve operation stability and the functional reliability requirement of automobile LNG fuel air feed pressure charging system, the manufacture application of each series automobiles LNG fuel air feed pressure charging system can be widely used in.
Seamless pipeline is more than four and is conducive to radiating effect.
Seamless pipeline arrangement after described assembling fin adopts the spread pattern head and the tail series connection be parallel to each other to be integrated.
Change Liquid Flow mode (labyrinth principle) by the combination of bridge piece, strengthen flow resistance, slow down flowing velocity, improve heat exchange pressurized effect; Forming liquid steam flow moves as backflow (labyrinth) formula fluid interchange; Be conducive to liquid vapour fluid interchange process in seamless pipeline, liquid vapour is made up of following current, crossing current, water conservancy diversion three kinds of modes, change the type of flow of gas-liquid, strengthen flow resistance, slow down flowing velocity, improve heat exchange pressurized effect.
