Title:
A cooling device of construction machinery
Document Type and Number:
Japanese Patent JP6136778
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve energy efficiency by effectively utilizing engine exhaust heat for cooling.SOLUTION: A thermoelectric conversion device 8, which performs heat absorption action absorbing exhaust heat of an engine and power generation action generating power with engine exhaust heat, is provided, and the engine exhaust heat is absorbed by the heat absorption action of the thermoelectric conversion device 8. While, a fan rotation frequency necessary for cooling is obtained from a power generation amount of the thermoelectric conversion device 8 corresponding to an engine exhaust heat amount, and a dynamo 3 is controlled so that the sum of the power generation amounts of the thermoelectric conversion device 8 and dynamo 3 is equal to power consumption of a fan motor 7 for rotating a fan with the necessary rotation frequency.
