Embodiment Construction

[0033]In order to solve the problem of heat-induced damage to heating instruments inside long-endurance aircraft, this invention designs a light-weight and efficient thermal control device, which transfers the heat from the heat source to the heat storage device composed of phase-change materials through a dredging heat transfer method , absorb and store the heat of self-heating equipment through phase change endothermic. Formulate the material selection and structure of the directional heat conduction scheme, the material selection and structure of the heat storage scheme, and the structural form between the heat transfer and heat storage components, and use theoretical analysis and numerical simulation methods to establish a thermal control model and optimize the efficiency of dredging , and finally design a complete set of lightweight and high-efficiency thermal control device.

Abstract

The invention relates to a transmitting-centralized heat management device for heating instruments of a long-endurance aircraft. The transmitting-centralized heat management device comprises transmitting channels and a centralized heat storage device. The centralized heat storage device comprises a plurality of heat storage units. Each heat storage unit comprises a base body and a framework distributed in the base body. The base body is composed of shape-stabilized phase-change materials. The framework is provided with a plurality of external interfaces located on the outer surface of the base body and a conduction pathway located in the base body, and received heat is transmitted to the base body through the framework. The transmitting channels are made of directional heat conduction materials or heat pipes and connected with heating sources and the external interfaces. The heat storage units made of various materials are arranged, each heat storage unit is made of different heat storage materials, and thus heat distribution and optimization are achieved. A large quantity of latent heat can be absorbed by the shape-stabilized phase-change materials, temperature rise is small after heat absorption, and the self weight is low; the appearances of the heat storage units are not changed after phase changing, and the whole centralized heat storage device is stable in structure. A novel approach is provided for heat dissipation of the aircraft.

Description

technical field [0001] The invention relates to a dredging-centralized thermal management device for long-endurance aircraft heating instruments and equipment, and belongs to the technical field of thermal management. Background technique [0002] Due to the rapid increase of the flight time of the aircraft, the heat generated by the flight control computer, battery pack and other instruments and equipment in the cabin continues to accumulate, which will eventually cause the temperature of the instruments and equipment to exceed the allowable value and fail to work normally. In addition, the long-term aerodynamic heating of the outer surface of the missile weapon will cause the temperature of the load-bearing shell to rise continuously, resulting in the continuous rise of the air temperature in the inner cavity, which adds unfavorable conditions to the heat dissipation of the equipment. The traditional fin-type passive heat dissipation method needs a good external heat dissi...
