Background technique
Coolant liquid circulates in engine-cooling system as thermal medium, absorbs extra heat in engine and warm
Degree increases, and flow out rear portion from engine water outlet reduces by heat exchanger temperature, and another part is still heat without cooling
Medium.The different coolant liquid of two parts temperature with suitable temperature enters engine after mixing in regulating valve, maintains engine
In suitable temperature, hot and cold medium completes heat transfer in internal heat exchanger, and thermal medium (coolant liquid) temperature reduces, cold medium
(cooling water) temperature increases, and cold medium after outer screw machine cooling device cooling down again by being recycled.
Cooling water is supplied by outer screw machine cooling-cycle device, and coolant liquid then recycles between engine and heat exchanger
Flowing, since the engine endurance test time is long, engine temperature is higher, and lacking or exhausting just not can guarantee for coolant liquid is started
Machine works under optimum state of temperature, and test is caused to interrupt or influence test result.
