Chapter 1Introduction1.1 origin and importance.  Since today. Vaccine storage, water, blood, viruses, bacteria or sperm to run out of places it is necessary to maintain the proper temperature, as well as to collect evidence of the murders happened, including collecting evidence and existing life.There will be time limited and must be maintained at the proper temperature so it will be able to check who is the culprit. Faculty who make a device that is used to maintain these organisms have a relatively high price. Therefore, the invention invention called Mini refrigerator for keeping up with these credentials. prior to the scientific laboratory.1.2 objectives. 1.2.1 to design and build mobile fridge Thermo dielectric made of cells. 2.2 in order to test the functionality of mobile invention. 2.2 in order to guide the development of the mobile fridge more efficient.1.3 assumptions Mobile fridge Thermo dielectric made from cells. The actual work.1.4 the variables used in the study of mobile from the fridge thermostat dielectric cell. 2.2 the variable is the number of thermo-electric and dielectric cell. 1.4.2 variable is capable of cooling.  1.4.3 the control variable is the type of the battery Tester. The number of battery Battery tray1.5 scope of testing. 1.5.1 external and internal temperature of the fridge thermostat electronic tharik cell mobile phone from. 1.5.2 the timer to measure the internal temperature of the external. Every 2 minutes to 20 minutes.  1.5.3 duplicate experiments done 3 times average 1.5.4 test locations College physics lab school? Device used to measure temperature is 1.5.5 multimeter and digital types.1.6 definition workshop 1.6.1 refrigerator refrigerator means that mobile design created is made from stainless steel size.W x 7 cm x h = criticize x 7 cm x 7 cm Thermo sheet fitted dielectric and thermal. ++ 1.6.2 cooling capability is the ability to cause the temperature inside the refrigerator, mobile made out of thermo electronic tharik cell. Lower temperatures are cool and the outside. 1.6.3 thermostat electronic cell is tharik endothermic electronically by.It appears that when the forecasts place thia has electricity flowing through the two links, one is cool. The other one is hot. The cooling of these has been adapted and developed into many other formats. Like the use of semiconductor 1.6.4 Semiconductor is a semiconductor, two types of P-type semiconductor and semiconductor.The type N on ceramic components While the electric phankrasae from N to P-per-point temperature will decrease and the acting sucked the heat from the surrounding area, the heat will be taking to the electron and the efficiency thermal offset, depending on the quantity of electricity and the amount of N and P.1.7 benefits expected to be received 1.7.1. the mobile refrigerator from the thermostat to the tharik electronic medical and other tasks. 1.7.2 the scientific process can be applied by an apply process and knowledge of physics, science comes from the invention of the refrigerator, mobile electronic thermostat tharik.  1.7.3. the appropriate methods to help reduce the problem to keep the bacteria or evidence the vaccine investigations that require the proper temperatures. 1.7.4., refrigerator, mobile phone prices are to be used in the various tasks to maintain the proper temperature,1.8 the budget. Thermo plate dielectric 1.8.1, size 2 inch x2 inch 60 Watt maximum number of 200 baht per plate. 1.8.2 and up, payroll sheets of stainless steel soknat x 7 cm x 7 cm 7 cm number of 150 baht. 1.8.3 up battery and wires the amount 50 baht. The total amount of all 400 baht/Cabinet
