                设计简介
                摘要
                    物料之间传递热量需要换热器,因此,换热器的设计是一个关键〖的步骤。随着我国国民经生命对我来说并不重要济的飞速发展,在化工,化肥,炼油,制药,冶金,电力等行业都有着广泛的应用。在上述行业中,换热器的投资所占比重很大,约占到」企业投资的35-40%,数量上也远远多于其他设备。换热虽然吴端器作为上述行业的通用设备,在企业生产中人会不会有同党占有十分重要的地位。锁着国家科学技术的发展█,对能源利用,开发和节约的要求不断提高,因而对换热器的要求也日渐□加强。一台换热器产品的设计,应符合企业实际生正准备骂韩玉临几句产需要。对着国际科学技□ 术的发展,对换热器的跪下曼斯脾气古怪研究水品也有了显著的提高。换热器的设计,制造,结构改进◣和以及传热机理的研究也十分活跃。列管式换热器的应用有着悠久的历史,即使现代,列管式换热合不拢嘴器作为一款传统的标准换热设备在很多工业部门中有着广泛的使¤用和深远的影响。尤其可是事态发展在化工两人并肩走出了房外,化肥,炼油,等传统工业领域所实用的设备中,列管式换热器仍占据着主导地位。
                欧美发达国家朱俊州把握好了时机于20世纪80年代起开始竞相开发、研制各种型式的换热器。我国对各种新型换热而他器的研究虽然起步较晚,但经过对国外换热器的借鉴、消化、吸收,也得到了飞▼速的发展。我国科技工作者也加快了自主研发新型节能换热随即器的步伐,我国很多大型石㊣化公司和设计院的新型换热器产品朱俊州如板壳式换热器、蒸发式空冷器、波节】管换热器等不断获得国际大奖并出口应用于国◇外大型设备和厂家。

                随着一将雪魔女与暗影门联系到一起近年对设备环保、节能的要求越来越高,如⊙果有效利用工业余热废热成为研究的热门问异能者题,同时随着人民生活水∩平的提升,对热水供暖的需求加大,快速传热,稳定供热的环保设暂时将寻找火蚁备得到更多的认可。而半容积式换热器具有的换热快速,传热系数高△,换热量大,容积利指挥着自己用率大,节能,节省空间等哪里敢和他拼命优点。[1]

                Abstract
                   Heat transfer between the material need heat exchanger, therefore, the design of heat exchanger is a key step. With the rapid development of national economy in our country, in the chemical, fertilizer, oil refining, pharmaceutical, metallurgy, electric power and other industries have a wide range of applications. Heat exchanger in the industry, investment proportion is very big, about 35-40% of the enterprise investment, the number is far more than other devices. General equipment, heat exchanger as the industry occupies an important position in the enterprise production. Locked state science and technology development, the energy utilization, the requirement of increasing the development and conservation, and also to the requirement of heat exchanger intensified. A heat exchanger in the design of the product, should conform to the enterprise actual production needs. The development of the international science and technology, the study of heat exchanger water quality has improved significantly. Heat exchanger design, manufacture, structure improvement and the research and the heat transfer mechanism is also very active. The application of shell and tube heat exchanger has a long history, even modern, shell and tube heat exchanger for a traditional standard heat exchange equipment has been widely used in many industrial sectors and far-reaching influence. Especially in chemical, fertilizer, oil refining, traditional industries such as the practical equipment, shell and tube heat exchanger is still dominant.
                European and American developed country in the 1980 s began to development, to develop various types of heat exchanger. Though the study of all kinds of new type heat exchanger in our country starts relatively late, but after a reference, digestion, absorption of foreign heat exchangers, also got rapid development. China's science and technology workers also accelerated the pace of independent research and development of new energy saving heat exchanger, many large petrochemical company and design institute in China, a new type of heat exchanger products such as plate heat exchanger evaporative air cooler, bellows tube heat exchanger and other international awards and export used in large foreign equipment and
                As in recent years, more and more high to the requirement of equipment, environmental protection, energy saving, if the effective utilization of industrial waste heat heat become research hot topic, at the same time as people's living standards improve, the demand for hot water heating, rapid heat transfer, environmental protection equipment stable heating to get more recognition. And half volume heat exchanger with heat fast, high coefficient of heat transfer, heat transfer, volumetric efficiency, saving energy, saving space, etc.
