PURPOSE: Provided is an environmental heat carrier for low temperature used in a heat pipe, which is not toxic and dose not cause abrasion against the heat pipe made of stainless, aluminium, copper, and soft steel. CONSTITUTION: The heat carrier is produced by mixing 88.5 to 89.5wt% of dimethyl ether, 8.5 to 9.5wt% of ethanol, 2.5 to 3.0wt% of ethylene glycol, and 1.0 to 1.5wt% of silicon oil for 20 minutes by using ultrasonic waves. The heat carrier can be used at a temperature of -40 to 70deg.C. Also, the heat carrier is liquid phase and odorless and has white color, nonionic property, and 6.5±0.5 of pH. |
