<p>PURPOSE:To prevent high voltage leakage in paint coating, paint is heated while maintaining insulation from heaters by use of outer cylinders and internal working fluid which is electrically isolated by insulating material. CONSTITUTION:An internally vacuum heat transfer pipe 5 containing a small amount of working fluid consists of outer container pipes of insulating material such as ceramic pipes which is internally lined with capillary wick, the pipes being attached at one ends to sheath heaters connected to power supply, and at the other ends to built-in paint pipes. This heat pipe 5 is used to heat paint. The inlet side of paint pipes is connected to the paint container 7 via the paint pump 6, and the outlet side is to the spray gun 8, through the paint circulating pumps, respectively. All the paint routes 10 form the paint container to spray gun, including the route built in the heat pipe, and route containing the circulating pump are electrically insulated from ground.</p> |
