14 Equipment for Heat Exchange
14个热交换设备
A wide variety of equipment is available for conducting heat exchange.一个是各种各样的设备进行热交换。
①Commercial units range in size form very small, double-pipe heat exchangers, with less than 1 ft2 of heat transfer surface, to large, air-cooled units called fin-fan heat exchangers because they consist of tubes with external peripheral fins and fans to force air past the tubes.
①商业单位的尺寸范围的形式非常小，双管换热器，小于1传热表面平方英尺到大，风冷机组称为鳍帆式换热器，因为它们与外部周边鳍片和风扇来管组成部队的空军过去的管。
Finned area in a single unit is as large as 20,000 ft2. By far the most common units are shell-and-tube heat exchangers, which come in a variety of configurations in sizes from 50 to 12,000 ft2.
翅片在一个单位面积高达二点〇万平方英尺大。目前为止，最常见的单位是壳管式换热器，这在不同的配置，尺寸从50到一点二〇〇万平方英尺来。


For specialized applications, compact heat exchangers are challenging shell-and-tube units.
对于专门的应用程序，紧凑式换热器是具有挑战性的壳管式单位。
Double-Pipe Heat Exchangers双管式换热器
Figure 14.1 Double-pipe heat exchangers: (a) single unit;
图14.1双管换热器：（一）单一单位;
(b) hairpin unit（二）发卡单位
A typical double-pipe units is shown in Figure 14.1a.② In its simplest form, it consists of an inner straight pipe of circular cross section, concentric to and supported within an outer straight pipe by means of packing glands. One stream flows through the inner pipe, while the other stream flows countercurrently through the annular passage between the outer wall of the inner pipe and the inner wall of the outer pipe. When more heat transfer area is need, return bends and heads are used with additional pipes to build a hairpin unit, as shown in Figure 14.1b. Hairpin units are available in sizes up to about 200 ft2 of heat transfer area, and are competitive with shell-and-tube exchangers to at least 100 ft2. To prevent sagging of the inner pipe with a resulting distortion of annular cross section, pipe length is limited to 20 ft. Therefore, a 200-ft2 unit of 3-in.-diameter inner pipes requires 10 hairpin connections. When one stream is at high temperature and/or high pressure, and/or is corrosive, it is passed through the inner pipe. ③If the other stream is a gas, longitudinal fins can be added to the outside surface of the inner pipe to help balance the inner and outer heat transfer resistances. If crystallization occurs from a liquid stream flowing through the inner pipe, scrapers can be added inside that pipe to prevent buildup of crystals on the inner wall. Double-pipe exchangers are not recommended for use in boiling or vaporization services.
一个典型的double-pipe单位被显示在图14.1a。②它最简单的形式,它由一个内在的直线管路圆形截面和支持,同心外层直管内采用填料密封垫。一个流流经内管流的流动,而另countercurrently通过环形通道之间的内管外壁及内部墙上的外管。当更多的热交换面积是需要的,返回弯曲并头采用附加管道单位建立一个发夹,如图14.1b。发夹单位可在尺寸约200平方尺的热交换面积,也很有竞争力与shell-and-tube换热器,至少100平方尺。防止下垂的内管产生的扭曲与环形横截面上管长度被限制到20英尺。因此,200-ft2 3-in.-diameter单位内部管道需要10个发夹固定连接。当一个人流则是在高温和/或高压,和/或颇具腐蚀性,它是通过内管。③如果其他流是一种气体,纵向翅可以加内管的外表面,有助于平衡的内部和外部的换热电阻。如果结晶发生从液体流流经内管,铲运机可补充内,管线上,以杜绝积聚晶体内墙上。Double-pipe器不推荐用滚水内或汽化服务。

在课堂上，他能积极主动思考问题并尽快给出解决方法。工程经济学需要分析核算的内容很多，他经常能比其他同学更快的给出正确的结果，有很强的分析和计算能力。结课考试，他获得了88.8的良好成绩，在班中排第四名（共42人）。另外，他个性十分积极乐观，乐于助人并很有公益心和责任感。因为每次见到他，总是满脸洋溢着自然的微笑。他主动担任课代表，帮助我收集和分发同学们的作业，课间总是主动擦黑板。在课间，我还时常看到他耐心的帮助同学解答难题，或者和周围很多同学有说有笑，关系非常融洽。
In the classroom, he always thought issues actively and found solution for them as soon as possible. The curriculum, Engineering Economics, requires analyzing and accounting a lot of contents, he often got correct results faster than other students, indicating his strong analytical and calculating power. In the final exams of this curriculum, he received a good result of 88.8 points, ranked the fourth in his class (42 students). In addition, his personality is very positive and optimistic, helpful, and full of public welfare spirit and sense of responsibility. Whenever I saw him, his face was always filled with a natural smile. He served as the curriculum representative initiatively, helped me collect and distribute the exercise books, cleaned blackboard actively. Between classes I often saw that he was answering questions for classmates with patience or chatting and laughing with many classmates, appearing very cordial relationship.
再次对他深入了解是由于他的毕业论文，那是2008年6月时我担任商学院毕业论文评审组组长，他的论文指导老师向我推荐指导，说他的论文很好的把理论和实际相结合，具有新颖性和独创性，我读后感觉果然如此。他表现出很强的创造力和敏锐的洞察力，能够利用所学理论知识分析当时发生的东航返航事件，并就此展开研究和提炼出自己的观点，展现出他严谨的学术态度和优异的研究潜质。后来，他的论文被评为只有1%的学生（共21087人）才有资格获得的校优秀论文，这也充分说明了他的创作和研究能力。而这一切是在他领导9名论文小组成员都顺利完成毕业论文并有两名获得优秀（>90分，共100分）的情况下完成，这期间需要不断和组员沟通，然后及时向导师反馈问题并提出自己的解决方法或建议，展现了他强烈的责任感、领导才干、良好的沟通和团队工作能力。
A better understanding of him was due to his dissertation, it was in June 2008 when I served as the Head of Dissertation Evaluation Team of the Business School, his dissertation was recommended to me by his dissertation tutor, saying: “This dissertation well combines theory with practice, has certain novelty and originality,” and I felt it was really the case. He demonstrated strong creativity and keen insight, and was able to use his theoretical knowledge to analyze the “Return flight” incident occurred in China Eastern Airlines, and conduct a study and summarize its own points of view, showing his rigorous academic attitude and excellent research potential. Eventually, his dissertation was evaluated the University’s excellent dissertation, which is granted to only 1% of the students (a total of 21087 students). It fully showed his creativity and research capabilities. Furthermore all this was realized under the conditions where all the 9 members of a team led by him successfully complete their dissertations and two of them received “excellent” evaluation (above 90 points in a total of 100 points). It needs for constant communication with his team members, and feeding back problems timely to tutor and proposing his own solutions or suggestions, so that demonstrating his strong sense of responsibility, leadership ability, good communication and team working abilities.

The dry salted meat products all adopt the method for a long time the traditional steam drying method, invest big, can take a large conventional energy, looking for a new type of drying method is very urgent. This paper studies two way to dry salted meat quality of influence. Through the determination of oven of three different drying temperature (45 ℃ 、55 ℃ 、65 ℃), under the sample water activity, peroxide value and acid value, and paint drying rate curve, and, in doing so, for further research of the solar drying law provides the basis. This paper studies show that when the oven drying, temperature for 50 ℃-60 ℃, dry effect is the best; When using the solar energy is dry, sunny weather for about a day can get finished product, dry the effect is good.

The drying method preserved meet products has long been the traditional steam drying, which demands large amounts of investment and conventional energy. Therefore, search for a new drying method is urgent. In this paper, the effect of two drying methods on the quality of preserved meat products were studied. The water activity, peroxide value and acidicity value of samples at different drying temperature (45℃、55℃、65℃) in oven were measured, and the drying rate curve was drwan. These evidences provide basis for further study of the laws of drying using solar energy. The results showed that the optimum drying effect was obtained at 50℃-60℃ when oven was used; the final product could be ottained in around one day in the fine weather when using solar energy for drying.

The traditional method to dry the salted meet production has long been the adoption of steam, which requires a large investment and costs much ordinary energy, so it has become most urgent to search a new way for drying. This article studies the different affections to the qualities of the meat production between two drying methods. By measuring the specimens' Aw,Peroxide Value and Acid value in three varying drying temperatures（45℃、55℃、65℃） in three different ovens, and drawing out their relavant curves of drying speed, we maneged to provide the basis for the deeper research of the regularity of the solar energy drying mothed.The research of this article shows that when adopting the oven for drying practice in the temperature 50℃-60℃, it has the best effect; When adopting the solar energy, the finished products can be produced within one day, and the effect is fine.
