Heat Transfer System

換 熱 系 統

一般介紹

換熱器（英語：heat exchanger），是將熱流體的部分熱量傳遞給冷流體的設備，使流體溫度達到工藝流程規定的指標的熱量交換設備，又稱熱交換器。材質一般有碳錳鋼、不銹鋼、鋯、鎳基（哈氏、蒙乃爾、因康鎳）合金及其它復合材料。

設備組成

常用列管換熱器主要是由殼體、傳熱管束、管板、折流板和管箱等部件組成。

工作原理

溫度不同的兩種流體在被壁面分開的空間里流動，通過壁面的導熱和流體在壁表面對流，兩種流體之間進行換熱。

應用領域

換熱器是化工、石油、動力、食品及其它許多工業部門的通用設備，在生產中占有重要地位。在化工生產中換熱器可作為加熱器、冷卻器、冷凝器、蒸發器和再沸器等，應用更加廣泛。

主要特點

  ●傳熱效率高，處理量大，能源利用率高。
  ●耐高溫高壓，耐腐蝕，適用介質廣泛。

General Introduction

Heat exchanger is a heat transfer equipment that transfers part of the heat from the hot fluid to the cold fluid to reach the fluid temperature specified in the process flow. The material is generally carbon manganese steel, stainless steel, zirconium, nickel based (Hastelloy, Monel, Inconel) alloy and other composite materials.

Composition

shell, tube bundle, tube sheet, folding plate, tube box and other components

Operational Principle

Two fluids with different temperatures flow in a space separated by the wall, and heat exchange occurs through the thermal conduction of the wall and the convection of the fluid on the wall surface.

Applicatioin

Heat exchanger is a general equipment in chemical,energy, food and many other industrial sectors, which occupies an important position in the production lines. In chemical production, heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler,etc.

Characteristic

  ●High transfer efficiency, high processing capacity, and high energy utilization rate
  ●High temperature and pressure resistance, corrosion resistance, wide application

  ●Simple structure, cost-effective, easy for repair and clean

  ●Hard structure, continuous operation, safe and reliable

Code Applied

GB、ASME

Type

hairpin, tube-shell, plate-type, double-pipe, spiral-plate, etc

Scope & Capability

thermal calculation, structure design, stress analysis, manufacture, modular construction of heat transfer system, maintenance, spare parts, etc
