摘要
 
 为了配合实验室的建设，能够让更多的学生学习冰箱的原理及构造，并加强学生的动手能力，本次毕业设计，制作一个间冷式电冰箱电气控制的实验模拟台，使其具有间冷式电冰箱电气控制的功能。该模拟实验台用于教学示范，是让电冰箱的电气控制系统平面化，即把布置在冰箱内的电气元件分解出来，平铺在模拟实验板上，组成一个实验台，便于学生识认各元器件及接插元件，更好的掌握间冷式电冰箱的电气控制系统。
 在设计时，考虑到模拟台的安全性，风扇、电热丝等有安全隐患存在的器件在外面应该加以保护；因为电冰箱的电气控制是强电，为保证安全，用于制作机箱面板的材料采用PVC树胶板，防止触电，而且在电源处加了电源自动切断保护器，当学生实验漏电时，可以马上切断电源；在模拟台的平面布置方面考虑尽量合理些，一方面利于学生的实验，另一方面也利于老师的检查；模拟台的在设计的时候，考虑到当学生操作时可以清楚看到电路的哪部分器件是否接通，可在部分器件上加入发光二极管；为了增强学生的实际动手检查能力和维修能力方面，考虑是否可以加入一些常见的故障。

To tie in with the construction of the laboratory, so that more students can learn the principles of the refrigerator and structure, and enhance the practical ability of students, the graduation project, create a cool refrigerator electric control of the experimental simulation platform so that it will have inter - cool refrigerator electric control functions. The simulation model for use in teaching is to allow the electrical control system for refrigerator planarization, which is arranged in the refrigerator by the decomposition of the electrical components, flat panel in the simulation experiment, a test-bed for easy identification of students Meets inserts the part various components and a better grasp of cool refrigerator electrical control system.
In the design, simulation, taking into account the security of Taiwan, fans, electric wire and other security devices that exist on the outside should be protected; because the refrigerator is a strong electric control power, in order to ensure security for the production of chassis panel PVC materials used gum boards, to prevent electric shock, but also in the Department added a power supply automatically cut off the protective device, when the students experiment leakage can be immediately cut off the power supply; in a simulated layout of Taiwan to consider more reasonable as far as possible, on the one hand, help students experiments, on the other hand, in favor of the teacher's examination; simulation platform in the design of the time, taking into account the operation when the students can clearly see which part of the circuit device is connected, you can add some light-emitting diode device; in order to enhance student examine the actual capacity and maintenance capabilities, consider the possibility of adding some common faults.
