APPARATUS FOR ADJUSTING TEMPERATURE OF EVAPORATION GAS TESTING DEVICE FOR VEHICLE

摘要

PURPOSE: An apparatus for adjusting a temperature of an evaporation gas testing device for a vehicle is provided to reduce installation cost by forming the apparatus using cooling water and pressurized air without using a cooler and a heater. CONSTITUTION: Cooling water is circulated through a cooling water tank(61). Cooling water contained in the cooling water tank(61) is circulated through a cooling/hot coil by means of a cooling water circulating pump(62). A cooling water feeding line(63) is provided to feed cooling water of the cooling water tank(61) into the cooling/hot coil. Cooling water contained in the cooling/hot coil(5) is returned into the cooling water tank(61) through a cooling water return line(64). Hot water is circulated through a hot water tank(65). A hot water circulating pump(66) is provided to circulate hot water through the cooling/hot coil. At least one vortex tube(69) is provided so as to feed low-temperature air into the cooling water tank(61). At least one vortex tube(69') is provided so as to feed high-temperature air into the hot water tank(65).
