摘要
 
 為了配合實驗室的建設，能夠讓更多的學生學習冰箱的原理及構造，并加強學生的動手能力，本次畢業設計，制作一個間冷式電冰箱電氣控制的實驗模擬臺，使其具有間冷式電冰箱電氣控制的功能。該模擬實驗臺用于教學示范，是讓電冰箱的電氣控制系統平面化，即把布置在冰箱內的電氣元件分解出來，平鋪在模擬實驗板上，組成一個實驗臺，便于學生識認各元器件及接插元件，更好的掌握間冷式電冰箱的電氣控制系統。
 在設計時，考慮到模擬臺的安全性，風扇、電熱絲等有安全隱患存在的器件在外面應該加以保護；因為電冰箱的電氣控制是強電，為保證安全，用于制作機箱面板的材料采用PVC樹膠板，防止觸電，而且在電源處加了電源自動切斷保護器，當學生實驗漏電時，可以馬上切斷電源；在模擬臺的平面布置方面考慮盡量合理些，一方面利于學生的實驗，另一方面也利于老師的檢查；模擬臺的在設計的時候，考慮到當學生操作時可以清楚看到電路的哪部分器件是否接通，可在部分器件上加入發光二極管；為了增強學生的實際動手檢查能力和維修能力方面，考慮是否可以加入一些常見的故障。

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.
