Problems solved by technology

In the past, the fuel thermal management technology adopted the fuel cooling mode with non-adjustable heat dissipation flow and the heat dissipation mode based on engine consumption. These two modes can only couple the flow in the same direction through the engine state, which will cause exhaustion under high consumption. Low thermal efficiency and insufficient heat removal capacity under low consumption conditions

Abstract

The invention provides a heat sink flow control method and device, and a storage medium. The method comprises steps that the temperature of each heat source system is obtained; when the temperature ofa target heat source system in each heat source system is not in a target preset scope of the target heat source system, the heat radiation flow is adjusted till the temperature of each heat source system is in the corresponding preset scope. The method is advantaged in that real-time dynamic control of the fuel heat sink flow is realized according to requirements of environmental control, hydraulic pressure and generator heat radiation is realized, heat radiation requirements of each system are not only met, but also an engine is made to consume high temperature hot oil as much as possible,and the fuel heat sink capacity is greatly improved.

Description

technical field [0001] Embodiments of the present invention relate to the electromechanical field, and in particular, relate to a heat sink flow control method, device and storage medium. Background technique [0002] The main function of the fuel thermal management system is to use fuel as the heat sink of the integrated thermal management system to dissipate heat from the environmental control system, hydraulic system, generator lubricating oil and other systems and ensure their use requirements, and at the same time control the intake fuel of the engine and auxiliary power unit. The temperature is within its acceptable range. [0003] Due to the large heat dissipation range of different systems under the whole use conditions, the whole machine heat dissipation threshold of the fuel system also changes from a narrow range value to a wide range value. In the past, the fuel thermal management technology adopted a fuel cooling mode with non-adjustable heat dissipation flow a...
