To satisfy the ground support requirements of the airborne liquid cooling system for aircraft repair or airport-related training

a new kind of multifunction ground liquid cooling camion for military aircrafts was designed and developed. This camion comprises five main parts

namely power supply system

coolant circulation system

cooling and heating system (single-stage vapor compression refrigeration cycle and electrical heater)

electric control system

vehicle chassis

and body. Results showed that the functions of coolant supplementation to the liquid cooling camion

coolant internal circulation in the liquid cooling camion

coolant addition and drain for liquid cooling system on board

and hot/cold coolant external circulation from the liquid cooling camion to the liquid cooling system on board

are achieved in the sample liquid cooling camion. Moreover

the liquid cooling system satisfied the setting temperatures of 15 ℃ and 10 ℃ in the heating and cooling modes after 24 and 20 min

respectively. Accordingly

the environmental temperatures of heating and cooling were 5 ℃ and 30 ℃

whereas the coolant flow was 200 L/min for both modes

with a temperature fluctuation of ±0.5 ℃.
