[In Russian. / En russe.]

Author(s) : CERNJAK B. M.

Type of article: Article

Summary

THE AUTHOR STUDIES THE EFFECT OF SPEED ON THE HEAT EXCHANGE, THROUGH THE DEFICIENT ZONES OF THE INSULATED BODY AND ON ITS HEAT BALANCE. THE STUDIES WERE MADE USING A THERMAL CONTROL PROCEDURE. THE AUTHOR EXPLAINS THE OPERATING PRINCIPLE OF THE INFORMATION-MEASUREMENT SYSTEM FOR THE SELECTION AND THE PROCESSING OF DATA AS FOR THE TEMPERATURES RECORDED UNDER OPERATING CONDITIONS. IT WAS ESTABLISHED THAT WHEN INCREASING THE TRUCK SPEED BY 40 KM/HR, THETHERMAL LOSSES IN THE FAULTY ZONE INCREASE BY 8-10% AND IN THE DOOR AREA BY 15-20%. THE OVERALL HEAT TRANSFER COEFFICIENT INCREASES BY 10% WITHOUT FAN AND 12% WITH TWO FANS AND AN INCREASE IN SPEED UP TO 80 KM/HR.
